Description

The present invention relates to a connector.

The following patent document discloses an invention relating to a method for adjusting the impedance of a terminal and its structure. This terminal is provided inside the connector, and the contact portion is partially cut out when viewed from the contact surface side. This reduces the capacitance of the contact portion of the terminal, making it possible to increase the impedance of the contact portion.

Japanese Patent Application Laid-Open No. 11-339921

However, in the configuration disclosed in the above patent document, the contact portion of the terminal is partially cut out when viewed from the contact surface side, so when mated with another connector, it is not possible to ensure a sufficient contact area with the terminal of the mating connector (connection target), which may result in an inability to ensure electrical continuity. Therefore, the above prior art has room for improvement in this regard.

The present invention takes the above facts into consideration and aims to obtain a connector that has excellent connection reliability with the connection object and can increase the impedance of the contact part at the terminal.

The connector according to the first aspect comprises a housing having a terminal having a contact portion that electrically contacts a connection object, a fitting portion that fits with the connection object along a fitting direction, and a terminal accommodating portion that accommodates the terminal with the contact surface of the contact portion exposed, and the terminal has a thin plate portion formed in a portion that includes at least a part of the contact portion and whose thickness dimension is set smaller than the thickness dimension of the other portion. Note that the "contact portion" refers to a portion that has a "contact surface" on one side in the thickness direction.

In the first aspect, the connector includes a housing having a fitting portion that fits with the connection object, and the housing is provided with a terminal accommodating portion that accommodates a terminal. The contact portion of the terminal electrically contacts the connection object at a contact surface exposed from the terminal accommodating portion. Here, the terminal has a thin plate portion formed in a portion including at least a part of the contact portion, and the dimension in the thickness direction is set smaller than the dimension in the thickness direction of the other portion. Since the cross-sectional area of the thin plate portion when cut along the thickness direction is reduced compared to the other portions of the terminal, it is possible to increase the impedance of at least a part of the contact portion. In addition, since the cross-sectional area of the thin plate portion is reduced while suppressing the reduction in the dimension of the contact surface of the terminal in the direction perpendicular to the fitting direction and perpendicular to the thickness direction (hereinafter simply referred to as the "width direction"), it is possible to increase the impedance of at least a part of the contact portion while ensuring the contact area when the terminal electrically contacts the connection object.

In the connector according to the second aspect, the terminal extends along the mating direction, and the thin plate portion is formed in a range from at least the entire area of the contact portion to the tip of the terminal. The tip of the terminal means the end of the terminal that is located on the tip side of the contact portion.

In the second aspect, the terminal extends along the mating direction, and the thin plate portion is formed at least in the range from the entire contact portion to the tip of the terminal. This reduces the cross-sectional area perpendicular to the extension direction of the terminal over a wide range, and increases the impedance over the entire contact portion.

The connector according to the third aspect is the first or second aspect, in which the terminal has a press-fit portion that is press-fitted into a press-fitted portion that constitutes part of the terminal accommodating portion of the housing, and the thin plate portion is formed in an area other than the press-fit portion.

In the third aspect, the thin plate portion is formed in an area other than the press-fit portion, so the thickness of the press-fit portion of the terminal is not reduced. This prevents the bending rigidity of the press-fit portion from decreasing, and prevents the press-fit portion from deforming when the terminal is pressed into the press-fit portion, which can cause the terminal to shift out of position relative to the terminal accommodating portion and ultimately the housing.

The connector according to the fourth aspect is any one of the first to third aspects, in which the terminal accommodating portion of the housing is formed with a receiving portion that abuts against a part of the back surface of the thin plate portion, which is the surface opposite the contact surface side of the thin plate portion in the thickness direction, and a non-contacting portion is provided that faces and is spaced apart from the part of the back surface of the thin plate portion other than the part.

In the fourth aspect, the receiving portion formed in the terminal accommodating portion of the housing abuts against a part of the back surface of the thin plate portion, which is the surface opposite the contact surface side of the thin plate portion in the thickness direction. In addition, the non-contact portion provided in the terminal accommodating portion of the housing faces and is spaced apart from the other part of the back surface of the thin plate portion. This forms an air layer between the other part of the back surface of the thin plate portion and the non-contact portion of the terminal accommodating portion. The air layer has a lower dielectric constant than the housing, so this air layer can increase the impedance in the thin plate portion.

The connector according to the fifth aspect is the fourth aspect of the third aspect, in which the non-contact portion is located closer to the press-fit portion than the receiving portion and has an inclined portion that is inclined toward the press-fit portion at a portion connected to the receiving portion and away from the back surface of the thin plate portion.

In the fifth aspect, the non-contact portion is located closer to the press-fit portion than the receiving portion and has an inclined portion at a portion where it connects to the receiving portion, and this inclined portion is inclined away from the back surface of the thin plate portion toward the press-fit portion. Therefore, when the terminal is moved along the extension direction of the terminal accommodating portion to the press-fit portion, near the non-contact portion, and near the receiving portion in this order in order to attach the terminal to the terminal accommodating portion, even if the tip side of the terminal abuts against the inclined portion, the inclined portion acts as a guide to allow the back surface of the thin plate portion of the terminal to abut against the receiving portion. In other words, when the terminal is attached to the housing, it is possible to prevent the terminal from buckling due to the tip side of the terminal getting caught near the boundary between the receiving portion and the non-contact portion.

As described above, the present invention has the excellent effect of providing excellent connection reliability with the connection object and increasing the impedance of the contact portion of the terminal.

First Embodiment
A first embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG.

In the following explanation, the arrow X shown in each figure indicates the front direction of the connector, the arrow Y indicates one side in the connector's width direction (right side), and the arrow Z indicates the upward direction of the connector. Furthermore, unless otherwise specified, the terms front-to-back, up-down, and width (left-to-right) refer to front-to-back in the front-to-back direction of the connector, up-down in the up-to-down direction of the connector, and width (left-to-right) in the connector's width direction (left-to-right). These directions are unrelated to the directions of the connector when in use. Additionally, some symbols may be omitted in each figure to make the drawings easier to read.

(overall structure)
1, a connector 10 according to this embodiment is a so-called plug, and includes a housing 12 and a plurality of terminals 14, with the lower side fixed to a circuit board (not shown). The connector 10 can be mated in the Z direction with a socket (not shown) as a connection object. In this embodiment, the mating direction Z coincides with the up-down direction of the connector 10, and in the following description, the mating direction Z may be referred to as the "up-down direction". Also, the "mating direction of the connector 10" will be abbreviated to "mating direction".

(housing)
The housing 12 is formed in a generally rectangular tubular shape (roughly rectangular parallelepiped shape), and is, for example, composed of an upper housing 12A and a lower housing 12B that constitutes the lower side of the upper housing 12A. The housing 12 is made of an insulating material such as synthetic resin. The left-right dimension of the housing 12 can be changed as appropriate depending on the number of terminals 14.

The upper component housing 12A has a peripheral wall portion 30 that defines a fitting hole 18 that is open upward and extends in the left-right direction. As shown in FIG. 2, the lower portion of the peripheral wall portion 30 is connected by the bottom wall 18A, and a central wall portion 20 protrudes upward from the center of the bottom wall 18A. The peripheral wall portion 30, the bottom wall 18A, and the central wall portion 20 that define the fitting hole 18 form a fitting portion 16 that fits with the socket (connection object) along the fitting direction. As shown in FIG. 1, the central wall portion 20 extends in the left-right direction, and both left and right ends of the central wall portion 20 are spaced apart from the peripheral wall portion 30.

A plurality of upper grooves 22A are formed on the front and rear surfaces of the central wall portion 20 shown in FIG. 4, aligned at equal intervals in the left-right direction. The upper grooves 22A form the upper portion of the terminal accommodating portion 22 that accommodates the terminal 14, and extend in the vertical direction. The terminal accommodating portion 22 also has a press-in hole 22B formed contiguous to the lower side of the upper groove 22A as a press-in portion, and this press-in hole 22B is formed penetrating the bottom wall 18A (see FIG. 2) in the vertical direction.

The upper groove 22A has a cross-sectional shape perpendicular to the longitudinal direction that opens outward in the front-rear direction with a pair of left and right side holding surfaces 22AA as side walls and a bottom holding surface 22AB that connects the inner ends of the pair of left and right side holding surfaces 22AA in the left-right direction. Note that the inner side in the front-rear direction refers to the inner direction in the front-rear direction of the central wall portion 20, and the outer side in the front-rear direction refers to the outer direction in the front-rear direction of the central wall portion 20. The dimension from one side holding surface 22AA to the other side holding surface 22AA is approximately the same as the width dimension of the contact surface 14A of the terminal 14.

In the upper groove 22A, the terminal 14 is arranged with the contact surface 14A on the upper and lower sides exposed to the outside, and the contact portion 14X of the terminal 14, which will be described later, is arranged to electrically contact the mating terminal (not shown) provided in the socket. The contact portion 14X and the mating terminal are abutted against each other in the front-to-rear direction.

The bottom holding surface 22AB has an upper receiving portion 22AC, a lower receiving portion 22AD, and an inclined portion 22AE as receiving portions. The upper receiving portion 22AC constitutes the upper portion of the bottom holding surface 22AB. On the other hand, the lower receiving portion 22AD is provided below the upper receiving portion 22AC and is positioned on the inner side in the front-to-rear direction of the central wall portion 20 relative to the upper receiving portion 22AC.

The inclined portion 22AE is provided between the upper receiving portion 22AC and the lower receiving portion 22AD. This inclined portion 22AE is formed to connect the lower end of the upper receiving portion 22AC and the upper end of the lower receiving portion 22AD, and specifically, it is inclined from the lower end of the upper receiving portion 22AC downward (toward the press-fit hole 22B) toward the inside in the front-to-rear direction of the central wall portion 20.

In addition, a recess 22AF is formed on the bottom holding surface 22AB. The recess 22AF is formed in a concave shape that opens outward in the front-rear direction with a pair of left and right recess side surfaces 22AG and a recess bottom surface 22AH as a non-contact portion that connects the front-rear inner ends of the pair of recess side surfaces 22AG in the left-right direction, and is formed in approximately the center of the bottom holding surface 22AB in the left-right direction. In other words, the bottom holding surface 22AB is formed in a pair on the left and right sides sandwiching the recess 22AF, and each abuts on the left and right (width) ends of the back surface 14G (see FIG. 3), which is the surface opposite the contact surface 14A side of the terminal 14 in the thickness direction. The depth of this recess 22AF, i.e., the dimension in the front-rear direction, is shallower (smaller) on the lower receiving portion 22AD side than on the upper receiving portion 22AC.

The lower end of the recess 22AF in the mating direction is located at an arbitrary position corresponding to the press-fit hole 22B in the bottom holding surface 22AB (not shown). On the other hand, the upper end of the recess 22AF in the mating direction is located below the tip guide portion 14E of the terminal 14, which will be described later. In other words, the recess 22AF is configured so that it cannot be seen from the outside when the terminal 14 is accommodated in the terminal accommodating portion 22.

(Terminal)
As shown in Fig. 4, the terminals 14 are manufactured by punching out a conductive metal plate into a predetermined elongated shape with the fitting direction Z as the longitudinal direction, and constitute a pair of front and rear terminal rows ( not shown). The front and rear terminal rows are configured such that a plurality of terminals 14 are arranged at equal intervals in the left-right direction with the thickness direction of the terminals 14 oriented along the front-rear direction. The plurality of terminals 14 in the front terminal row and the plurality of terminals 14 in the rear terminal row are formed to have the same shape, but are arranged in a posture opposite to each other in the front-rear direction (not shown). The plurality of terminals 14 in the front terminal row are provided on the front side of the central wall portion 20 of the fitting portion 16, and the plurality of terminals 14 in the rear terminal row are provided on the rear side of the central wall portion 20 of the fitting portion 16.

Each terminal 14 is held in the terminal accommodating portion 22 and has a contact portion 14X of the terminal 14 located in the upper groove 22A of the terminal accommodating portion 22, a press-in portion 14B provided below the contact portion 14X and pressed into the press-in hole 22B, a connection portion 14C (see FIG. 2) extending downward from the end of the press-in portion 14B opposite the contact portion 14X and further bent outward in the front-to-rear direction to be fixed to the circuit board, and a general portion 14D located between the contact portion 14X and the press-in portion 14B. Note that in FIG. 4, the terminal 14 is partially omitted in order to make the inside of the terminal accommodating portion 22 easier to understand.

The contact surface 14A of the contact portion 14X is formed in a generally planar shape that is continuous with the front-rear outer surface of the press-fit portion 14B, the front-rear outer surface of the general portion 14D, and the front-rear outer surface of a portion of the connection portion 14C. The width dimension of the general portion 14D between the contact portion 14X and the press-fit portion 14B is set smaller than the width dimension of the contact surface 14A. At the upper side of the contact portion 14X, i.e., at the tip of the upper portion of the terminal 14, a tip guide portion 14E is formed so that the width and thickness dimensions decrease toward the upper side.

(Thin plate part)
As shown in Fig. 3, the terminal 14 is formed with a thin plate portion 14F. The thin plate portion 14F is formed in the vicinity of the press-fit portion 14B of the terminal 14 and in the range from the upper side (general portion 14D) of the press-fit portion 14B to the tip guide portion 14E (i.e., the range including the entire area of the contact portion 14X), and the dimension in the thickness direction is set to be smaller than the dimensions in the thickness direction of other portions. A thin plate portion back surface 14F1, which is the surface of the thin plate portion 14F opposite to the contact surface 14A side in the thickness direction, is disposed on the inner side in the thickness direction of the terminal 14 than other portions of the back surface 14G of the terminal 14.

As shown in FIG. 5, a portion of the thin plate portion back surface 14F1 is in contact with the upper receiving portion 22AC of the bottom holding surface 22AB. Specifically, the area from the portion of the back surface 14G of the thin plate portion 14F corresponding to the tip guide portion 14E to the portion near the upper side of the general portion 14D is in contact with the upper receiving portion 22AC. The upper groove 22A of the terminal accommodating portion 22 is provided with a side non-contact portion 22AZ that faces the other portion of the thin plate portion back surface 14F1 at a distance below the upper receiving portion 22AC. The recess bottom surface 22AH (see FIG. 4) described above also faces the other portion of the thin plate portion back surface 14F1 at a distance.

The side non-contact portion 22AZ is located below the upper receiving portion 22AC (closer to the press-fit hole 22B (see FIG. 4)) and has the aforementioned inclined portion 22AE at a portion where it connects to the upper receiving portion 22AC, and the inclined portion 22AE is inclined downward (toward the press-fit hole 22B) toward the side away from the thin plate back surface 14F1. In other words, the side non-contact portion 22AZ is formed by the inclined portion 22AE and a part of the lower receiving portion 22AD. A space SA is formed between the side non-contact portion 22AZ and the lower portion of the thin plate back surface 14F1.

(Functions and Effects of the First Embodiment)
Next, the effects of this embodiment will be described.

In this embodiment, as shown in FIG. 1, the connector 10 includes a housing 12 having a mating portion 16 that mates with a socket (connection object), and a terminal accommodating portion 22 that accommodates the terminal 14 is provided in the central wall portion 20 of the mating portion 16, as shown in FIG. 4. The terminal 14 electrically contacts the socket at the contact surface 14A exposed from the terminal accommodating portion 22 and has a thin plate portion 14F. The thin plate portion 14F is formed in a portion including the contact portion 14X, and the thickness dimension is set smaller than the thickness dimension of the other portions. Therefore, the cross-sectional area of the thin plate portion 14F of the terminal 14 when cut along the thickness direction is reduced compared to the other portions of the terminal 14, and the impedance of the contact portion 14X can be increased. In addition, the thin plate portion 14F reduces the cross-sectional area while suppressing the reduction in the width dimension of the contact surface 14A of the terminal 14, so that it is possible to increase the impedance of the contact portion 14X while ensuring the contact area when the terminal 14 electrically contacts the socket, and to prevent the socket from getting stuck in the reduced width portion of the terminal 14 and being unable to ensure electrical continuity. As a result, the connector 10 of this embodiment has excellent connection reliability with the socket (connection object) and can increase the impedance of the contact portion 14X of the terminal 14.

The terminal 14 extends along the mating direction, and the thin plate portion 14F is formed in the range from the area including the entire contact portion 14X to the tip guide portion 14E. This reduces the cross-sectional area perpendicular to the extension direction of the terminal 14 over a wide range, and increases the impedance in the range from the area including the entire contact portion 14X to the tip guide portion 14E.

Furthermore, because the thin plate portion 14F is formed in an area other than the press-fit portion 14B, the thickness of the press-fit portion 14B of the terminal 14 is not reduced. This prevents the bending rigidity of the press-fit portion 14B from decreasing, and therefore prevents the press-fit portion 14B from deforming when the terminal 14 is pressed into the press-fit hole 22B, causing the position of the terminal 14 to shift relative to the terminal accommodating portion 22 and ultimately the housing 12.

The upper receiving portion 22AC formed in the upper groove 22A of the housing 12 shown in FIG. 5 abuts against a part of the thin plate back surface 14F1. The recess bottom surface 22AH (see FIG. 4) and the side non-contact portion 22AZ provided in the upper groove 22A of the housing 12 face the thin plate back surface 14F1 at a distance from the other parts of the thin plate back surface 14F1. This forms an air layer between the recess bottom surface 22AH (see FIG. 4) and the side non-contact portion 22AZ of the upper groove 22A and the part of the thin plate back surface 14F1. The air layer has a lower dielectric constant than the housing 12, so this air layer can increase the impedance of the thin plate portion 14F.

Furthermore, the side non-contact portion 22AZ is located below the upper receiving portion 22AC (the press-fit hole 22B (see FIG. 2) side) and has an inclined portion 22AE at a portion where it connects to the upper receiving portion 22AC, and this inclined portion 22AE is inclined toward the side away from the thin plate portion back surface 14F1 toward the downward side (the press-fit hole 22B (see FIG. 2) side). Therefore, when the terminal 14 is moved from the downward side along the extension direction of the terminal accommodating portion 22 to the press-fit hole 22B (see FIG. 2), the vicinity of the side non-contact portion 22AZ, and the vicinity of the upper receiving portion 22AC in this order in order to attach the terminal 14 to the terminal accommodating portion 22, even if the tip guide portion 14E of the terminal 14 abuts against the inclined portion 22AE, the inclined portion 22AE acts as a guide so that the thin plate portion back surface 14F1 of the terminal 14 can abut against the upper receiving portion 22AC. In other words, when the terminal 14 is attached to the housing 12, the terminal 14 is prevented from buckling due to the tip guide portion 14E of the terminal 14 getting caught near the boundary between the upper receiving portion 22AC and the side non-contact portion 22AZ.

In this embodiment, the general portion 14D shown in FIG. 4 has a smaller width dimension than the contact portion 14X, forming a gap between the general portion 14D and the side holding surface 22AA and increasing impedance. On the other hand, the width dimension of the contact portion 14X is not reduced, so the contact area when the contact surface 14A comes into contact with the socket can be secured.

Second Embodiment
Next, a connector according to a second embodiment of the present invention will be described with reference to Figures 6 and 7. Note that the same components as those in the first embodiment and the like are designated by the same reference numerals and the description thereof will be omitted.

The connector 60 according to the second embodiment has the same basic configuration as the first embodiment, but is characterized in that a step is formed on the contact surface 62A side of the terminal 62.

(overall structure)
That is, as shown in Fig. 6, the connector 60 according to this embodiment is a so-called plug, and is configured to include a housing 64 and a plurality of terminals 62, and the lower side is fixed to a circuit board (not shown). The connector 60 can be fitted in a socket (not shown) as a connection object in the Z direction. In this embodiment, the fitting direction Z coincides with the up-down direction of the connector 60, and in the following description, the fitting direction Z may be referred to as the "up-down direction". Also, the "fitting direction of the connector 60" will be abbreviated to "fitting direction".

(housing)
The housing 64 is formed in a generally rectangular tubular shape (roughly rectangular parallelepiped shape). The housing 64 is made of an insulating material such as synthetic resin. The left-right dimension of the housing 64 can be changed as appropriate depending on the number of terminals 62.

The housing 64 is provided with a fitting portion 66 that is generally similar to the fitting portion 16 (see FIG. 1) of the first embodiment. The fitting portion 66 is configured to include a central wall portion 70 that protrudes upward from the center of a bottom wall 68 that is generally similar to the bottom wall 18A (see FIG. 2) of the first embodiment. The central wall portion 70 is generally configured similarly to the central wall portion 20 (see FIG. 4) of the first embodiment. A plurality of upper grooves 72A are formed on the front and rear surfaces of the central wall portion 70, and are arranged at equal intervals in the left-right direction. The upper grooves 72A form the upper portion of the terminal accommodating portion 72 that accommodates the terminal 62 and extend in the vertical direction. The terminal accommodating portion 72 also has a press-fit hole 22B formed continuously below the upper groove 72A.

The upper groove 72A has a cross-sectional shape perpendicular to the longitudinal direction that is open outward in the front-to-rear direction and is made up of a pair of left and right side holding surfaces 22AA as side walls, and a planar bottom holding surface 72AA that connects the inner ends of the pair of left and right side holding surfaces 22AA in the left-to-right direction. In addition, a recess 22AF is formed in the bottom holding surface 72AA.

In the upper groove 72A, the terminal 62 is arranged with the contact surface 62A on the upper and lower sides exposed to the outside, and a contact portion 62X (described later) of the terminal 62 is arranged, which is in electrical contact with a mating terminal (not shown) provided in the socket. The contact portion 62X and the mating terminal are in contact with each other in the front-to-rear direction.

(Terminal)
As shown in Fig. 7, the terminals 62 are manufactured by punching out a conductive metal plate into a predetermined elongated shape with the fitting direction Z as the longitudinal direction, and constitute a pair of front and rear terminal rows (not shown). The front and rear terminal rows are configured such that the multiple terminals 62 shown in Fig. 6 are arranged at equal intervals in the left and right direction with the thickness direction of the terminals 62 oriented along the front-rear direction. The multiple terminals 62 in the front terminal row and the multiple terminals 62 in the rear terminal row are formed to have the same shape, but are arranged in opposite orientations in the front-rear direction. The multiple terminals 62 in the front terminal row are provided on the front side of the central wall portion 70 of the fitting portion 66, and the multiple terminals 62 in the rear terminal row are provided on the rear side of the central wall portion 70 of the fitting portion 66.

Each terminal 62 is held in the terminal accommodating portion 72 of the fitting portion 66, and has a contact portion 62X of the terminal 62 located in the upper groove 72A of the terminal accommodating portion 72, a press-in portion 14B extending downward from the contact portion 62X and pressed into the press-in hole 22B, a connection portion 14C (see FIG. 2) extending downward from the end of the press-in portion 14B opposite the contact portion 62X and further bent outward in the front-to-rear direction to be fixed to the circuit board, and a general portion 62D located between the contact portion 62X and the press-in portion 14B. Note that in FIG. 6, the terminal 62 is partially omitted in order to make the inside of the terminal accommodating portion 72 easier to understand.

The width of the general portion 62D between the contact portion 62X and the press-fit hole 22B is set smaller than the width of the contact surface 62A. In addition, a tip guide portion 62E is formed on the upper side of the contact portion 62X, i.e., on the tip of the upper portion of the terminal 62, so that the width and thickness dimensions decrease toward the upper side.

(Thin plate part)
As shown in Fig. 7, the terminal 62 is formed with a thin plate portion 62B. As shown in Fig. 6, the thin plate portion 62B is formed in the vicinity of the press-fit hole 22B of the terminal 62 and in the range from the upper side of the press-fit hole 22B (general portion 62D) to the tip guide portion 62E, and the dimension in the thickness direction is set to be smaller than the dimension in the thickness direction of other portions. The surface of the thin plate portion 62B on the contact surface 62A side is disposed on the inner side in the thickness direction of the terminal 62 than the surface facing the same side in the press-fit portion 14B, and a step is formed on the contact surface 62A side of the terminal 62. On the other hand, the back surface 62C (see Fig. 7) of the terminal 62 is formed in a flat shape.

A part of the thin plate portion back surface 62B1 (see FIG. 7), which is the surface on the opposite side in the thickness direction from the contact surface 62A of the thin plate portion 62B, is in contact with the bottom holding surface 72AA, which serves as a receiving portion in the upper groove 72A. As a result, a space SB is formed between the part other than the thin plate portion back surface 62B1 (see FIG. 7) and the recess bottom surface 22AH of the recess 22AF.

(Actions and Effects of the Second Embodiment)
Next, the operation and effects of the second embodiment will be described.

The above configuration is similar to the connector 10 of the first embodiment except that a step is formed on the contact surface 62A side of the terminal 62, so the same effects as the first embodiment can be obtained. In addition, the bottom holding surface 72AA of the housing 64 is flat in correspondence with the back surface 62C of the terminal 62, which has no step, making it easier to manufacture.

(Supplementary explanation of the embodiment)
In the first and second embodiments described above, the thin plate portions 14F, 62B are formed in the range from the vicinity of the press-fit portion 14B of the terminals 14, 62 to the tip guide portions 14E, 62E, but the thin plate portions may be provided in part of the contact portions 14X, 62X, or in a portion including part of the contact portions 14X, 62X.

In addition, the thin plate portions 14F, 62B are formed in areas other than the press-fit portion 14B of the terminals 14, 62, but are not limited thereto and may be formed in areas including the contact portions 14X, 62X and the press-fit portion 14B.

Furthermore, the general portions 14D and 62D are set to have a smaller width dimension than the thin plate portions 14F and 62B, but are not limited to this setting.

Furthermore, the lower end position of the upper receiving portion 22AC of the first embodiment described above may be set higher than the position shown in FIG. 5. In that case, the space SA becomes larger, and the impedance of the contact portion 14X can be further increased.
