1227581 发明, description of the invention (the description of the invention should state: the technical field to which the invention belongs, the prior art, the content, the embodiments, and the drawings)

I: The technical field of the inventor J Field of the invention The present invention relates to coaxial connectors and cutting devices. More specifically, 5 relates to coaxial connectors mounted on circuit boards and cutting them. Switch off device.

L · U [Learning details] At present, electronic devices, such as mobile phones and laptops, are becoming more and more miniaturized and parts are densely arranged. For example, the coaxial connector 100, which is conventionally installed using general surface mounting technology, is an internal coaxial connector, as shown in Figures 13 (a) & (b), and includes a pair of contact portions. It can be in contact with the contact part of the corresponding external connector (not shown) and is electrically connected to each other, an insulator 107 supporting the contact part 103 such as «11, etc., and a metal case 15 for housing the insulator 丨 07 1〇1. The housing 101 has a substantially cylindrical connecting section portion 101a, which is connected to the corresponding external connector, and the contact portions 103, 103, and the contact portions 1G3 are installed near the center position. The 1G3 bifurcated tip is substantially U-shaped. The contact portion 103 is provided with a sub-signal transmitted in a signal terminal 105 and the signal terminal 105 is connected to a conductive pad of 20 on the circuit board. Since the flux and solder used to mount the coaxial connector 电路 on the circuit board may reduce the electrical transmission properties by blocking the contact portion 103, the bottom portion of the contact portion 103 is slightly bent to form a gap 120, It is used to prevent the flux and solder from moving up with the contact portion. Here, 1227581 发明, description of the invention The co-solvent is used to chemically clean an oxide film on a metal surface for welding and improving welding. The gap 120 has a function of forming a solder pin at the position where the coaxial connector 100 is soldered to the circuit board. In addition, the contact portion 103 is opposite to one of the tip ends 106 of the signal terminal 105, and is arranged in a recess 1009 formed on the bottom of the insulator 107 so that the contact portion 103 can be fixed to the insulator 107. A pair of ground terminals 11 and 11 are provided on the left and right sides of the casing 101, which are connected to the ground pad on the circuit board and can be grounded. [Problems to be solved] The above-mentioned conventional coaxial connector 100 with surface mounting technology only has two ground terminals 110, 110, one on the right and the other on the left, which are connected to the ground pad on the circuit board. Thereby, in addition to having a limited grounding property for high frequency waves, the gaps 12 and 15 are formed at the bottom of the contact portion 03 to prevent the flux and the solder from moving upward to form the solder at the soldering position. The foot has a spring function, and in order to fasten the contact portion 103, the bending slave is formed longer, and the push-in section is formed deeper; however, when the corresponding outer connector is connected, the contact portion 1 〇3 The bottom chest can be moved down (in the direction of arrow A), and sometimes it may be left or right misaligned. When the bottom portion 103a of the contact portion 103 is moved, not only the contact portion 103 may be deformed, but also the signal terminal 105 may be detached from the coil or the coil itself may be detached from the circuit board. In addition, a problem may arise in that the contact section of the contact portion of the corresponding external connector becomes unstable. On the other hand, the longer the tip H) 6, the worse the electrical transmission properties. Therefore, the tip should be made as short as possible. As shown in Figure 13 (b), the conventional coaxial connector 100 prevents a section of the housing 101 from contacting the insulator. When the corresponding external connector is connected, as the corresponding external connector is connected, it will A force is applied to the section and a weakened section is generated so that the casing 101 may be deformed. In the case of connectors such as Rong, if the circuit board is pushed sharply or something hits the circuit board and a force is applied to the coaxial connector 100, this force will be directly placed on the signal terminal 1 〇5 and the contact surface may be damaged so that the signal terminal 105 may be detached from the circuit board or the pad may be detached from the 104 circuit board. In addition, the coaxial connector itself may be detached from the circuit board. In the case of FPC, this phenomenon is more intense. In the case where the connectors are connected, even when the device is to be removed by using the device, the conventional coaxial connector does not have a hook portion for the device to hold, and if the device is forced, When separated, the operator's hand or 15 device may touch the conductive part of the circuit board and the signal terminal 105 may be deformed. The present invention can cope with these problems and an object thereof is to provide a coaxial connector which can strengthen the high-frequency grounding performance and prevent the contact portion from moving when the corresponding connector is connected. 2 In addition, the object of the present invention is to provide a coaxial connector in which the mounting strength can be improved so that the coaxial connector mounted on the circuit board cannot be easily detached. In addition, the object of the present invention is to provide a coaxial connector, which can prevent the signal terminal from being detached from the circuit board and prevent 1227581 from being detached from the circuit board. The invention describes the contact position and the contact portion of the corresponding connector fixed. In addition, an object of the present invention is to provide a coaxial connector, wherein even when the connected coaxial connector is removed using a device, an operator's hand or the device will not destroy the communication terminal and provide the purpose.

L " 5ST] [Preferred embodiment of the present invention] 1227581 发明 Description of the invention In the following, the embodiment of the coaxial connector of the present invention will be described in detail with reference to the drawings. Fig. 1 (a) is a top plan view of the first embodiment of the coaxial connector according to the present invention. Fig. 1 (_ is a side plan view viewed from arrow A, and Fig. 1 (c) is a bottom view. Plan view. Fig. 2 is a cross-sectional view of the coaxial connector shown in Fig. 5 and Fig. 5, and Fig. 2 (b) is a side cross-sectional view of the same connector connected to a corresponding external connector. The coaxial connector 1 described in the drawing is a surface-mounted type, that is, a coaxial connector of a type of SMT, and as can be seen in FIG. 2 (b), it is mounted on the FPC (flexible printing) Circuit) board 3. The circuit board 3 10 may be -PCB (printed circuit is reversed), which is a rigid board type "or the above-mentioned FPC with specific elasticity, and other users. In addition, in the drawing, -Corresponding external connection H 50 is mounted on -PCB 6G ±, and # can also be mounted on-FPC board. The coaxial connector 丨 is formed with _ contact portion 13, which is in contact with a contact portion 53 of the external connector 50. For contact and electrical connection, an insulator 17 made of synthetic 15 resin to hold the contact portion 13, and a metal case 11 to accommodate the insulator 17. The case u has The cylindrical connecting section 11a on the real f is connected to the corresponding outer connector 50, and in the middle of the connecting section 11a, the contact section 13 with u-shaped ends can be placed inside to stand upright The contact portion 13 is provided with a signal terminal 15 at an end portion 20 on a side portion of the circuit board 3, and an electronic signal can be transmitted through the signal terminal ^ and the signal terminal 15 and a conduction on the circuit board 3 Pad connection. The housing Η accommodates the insulator 17 so that the bottom of the substantially cylindrical connecting section portion iia contacts the insulator 17. In this way, when the corresponding outer connector 50 is connected, even if due to the connection effect, Apply a force to the connecting section 12 1227581 发明, invention description 11a, since the connecting section 11a is held by the insulator 17, the housing 11 will not deform. In addition, because the connecting section 丨 丨& It is in contact with the insulator 17 and held by it, so a positioning mechanism can be set on the connecting section 11a and the insulator 17. 5 10 15 20 To prevent the refining agent and fresh tin from moving upwards, bend it slightly A bottom 12 a of the contact portion 13 is formed with a gap 12 in the contact. The bottom portion 13a of the portion 13. Except when a ridge is formed on the soldered portion when the far coaxial connector 1 is mounted on the circuit board, the gap 12 allows the contact portion 13 to move in and thereby the elastic function can improve the correspondence. The contact effect of the connector. And the opposite end 16 of the contact portion 13 and the signal terminal 15 is bent to a slight height. The end 16 is held by a holder 19 which is the upper surface of the recessed hole 18 and the recessed hole. A depression 18 is formed on the inner surface of the insulator 17 above and below the space where the contact portion 13 is placed. As a result, the contact 胄 13 can be held by the insulator 17. In addition, as shown in FIGS. 8 (a) and (b), the recessed hole 18 has a narrow opening on the inner surface of the insulator 17 and a wide space therein. Due to this feature, and in the case of being connected to the corresponding connector 50, the contact portion 13's end 16 can be fastened and held when it is inserted into the recess 18), so the contact portion 13 can be prevented from being left Or right * justified. The end 16 is bent to have a slight height, which is located near the inner surface side, so that compared with a conventional coaxial connector, the stub is smaller and the electric transmission property can be improved. To the left and right, the main ground terminals 20, 20 and the secondary ground terminal 21 are formed in order to be grounded by the connection connected to the circuit board. The main ground terminal 20 is formed at a relative position with respect to the body 11 and protrudes from the bottom section of the cylindrical casing u. 13 1227581 发明, description of the invention The main ground terminals are in contact with the ground pads, and their ends are bent upwards. The main ground terminals 20 are designed to be used for grounding at the contact portions with the contact pads. The upper surfaces of the main ground terminals 20 are the hooks 20a. When the coaxial connector is to be removed from the corresponding external connector 50, the pressing section of the device 40A, 40B, 40C, 40D, 40E is used. 41, 41 can be hooked 10 15 20

The case 11 causes the secondary ground terminals 21 to be arranged along a circle centered on the center of the case 11. In this embodiment, the four secondary ground terminals 21 are located at 90 degrees each. The number of such secondary ground terminals 21 to be set up does not limit the number, and since there are two primary ground terminals 20, at least a secondary ground terminal is required. As in this embodiment, there should be four Secondary ground terminal 21. Of course, it is also possible to set up more secondary ground terminals 21; placed with the largest possible surface area, it needs to be connected to such ground pads. These grounding grounds also need to be installed so that they cover the large surface area of the circuit board 3, so that they can be connected with the main grounding terminals with large surface areas.

The ground terminal 21 should be in contact. In this way, since the coaxial connector maintains the same distance to the housing u when mounted on the circuit board 3, no load is concentrated on any of these primary or secondary ground terminals 2 (), 2ι, and The coaxial connector 1 can be tightened with a si wire. In addition, the ends of the secondary ground terminals 21 are designed to have large contact portions in contact with the ground 塾 on the circuit board, and therefore, compared with the conventional coaxial connector, the coaxial connector has better grounding to high frequency. performance. By forming in this way, the ground terminals 20, 21 can be effectively prevented from being separated from the ground planes and the ground planes from the circuit board 3. The secondary ground terminals 21 do not have to be located directly on the center of the housing u 14 1227581 发明, the invention description circle, the ground pads on the circuit board 3 may be located near the circle and located on the circle The main and cut ground materials 2G, 21 meet, so that it can also be located on a circle centered on the shell 11. 5 10

The end of the terminal 21 to be grounded is located beyond the signal terminal: 5 wide outside. As indicated in the first figure, this signal ... 5 is located in a dotted line connecting the end of the terminal 21 to be grounded. Because of this feature, when the 5 car connector 1 is connected to the pin connector 5g, even if the circuit board is shaken by 3 forks or something collides and a force is applied to the coaxial connector $, the force will be located in the mysterious Waiting for one person to ground the terminal 21 without applying it directly to the signal terminal can prevent the signal terminal 15 from detaching from the pad and the pad from detaching from the circuit board.

On the one hand, ‘coaxial connector 1 is to be mounted on the circuit board 3. In addition to SMT, bumps can also be used. The second embodiment shown in Figs. 3 (a) and 3 (b) is mounted on the circuit board 3 i by using bumps. Here, FIG. 3 (b) is a side plan view of the coaxial connector ι using these bumps, and FIG. 3 (b) is a bottom plan view thereof. As shown in Fig. 3, the second embodiment of the coaxial connector 1 has substantially spherical solder bumps 25 which are located at seven positions along the bottom surface of the housing 11. With these bumps, the coaxial connector 1 is grounded and mounted on the circuit board 3 ±. In addition, a signal terminal 15 is in contact with the ground pad on the circuit board 3 by using a solder bump 25 as in the case of 20. In addition to the solder bumps described above, the bumps may be formed of a metal such as copper and gold and of course they may be used. The other forming parts are the same as those of the first embodiment, and therefore detailed descriptions are omitted. Figures 4 (a) and (b) show a coaxial connector with an extension type, in which the ground 15 1227581 发明, description of the invention Terminals 27, 27 are inserted into the through holes (not shown) on the circuit board 3 and grounded.

The third embodiment of the coaxial connector has a ground terminal 27 protruding downward from seven positions along the bottom surface of the casing, and is mounted on the circuit board 3. Similarly, a signal terminal 15 is formed to protrude downward from the bottom of the casing 11 and is installed to be inserted into a perforation (not shown) on the circuit board 3. The other configurations are similar to those of the first embodiment, so detailed descriptions thereof are omitted. The above-mentioned first embodiment (SMT type), second embodiment (bump type) 10, and third embodiment (protrusion type) are not necessarily included separately and can be combined. Figure 5 (a) shows the bottom plan view of the merged type of bump type and SMT type. When the coaxial connector shown in FIG. 5 (a) has two main ground terminals 20 and five secondary ground terminals 21, the number is one more than the first embodiment, and each of them is mounted on the circuit board 3. A signal terminal 15 is mounted on the electric circuit board 3 by a bump. In this state, the signal terminal 15 is located inside the housing u, so that even when a load is applied when the coaxial connector 丨 is connected to the corresponding external connector 50, this load will be applied to the secondary ground Terminal 21, but not directly applied to this signal terminal 15. Figure 5 (b) shows the bottom plan view 20 of the merged version of the extension type and the SMT type. When the coaxial connector 1 shown in FIG. 5 (b) has two main ground terminals 20 and five secondary ground terminals 21, and each of them is mounted on the circuit board 3, the number terminal 15 is formed from the casing 11 The bottom is convex, and the coaxial connector 1 is installed by inserting the protruding portion into a through hole (not shown) formed on the circuit board 3. 16 1227581 发明, description of the invention Fig. 6 (a) shows the bottom plan view of the combined type of the protruding type and the convex type. When the coaxial connector shown in FIG. 6 (a) has solder bumps 25 at seven positions along the round bottom surface of the casing 11, so that the casing n can be grounded and mounted on the circuit board On 3, a signal terminal 15 is formed to protrude from the bottom of the 5 housing 11, and the coaxial connector is installed by inserting the protruding portion into a through hole (not shown) formed on the circuit board 3. Inside. Fig. 6 (b) shows the bottom plan view of the combined type of the bump type and the projected type. When the coaxial connector j shown in FIG. 6 (b) has ground terminals 27, 27, it protrudes downward at seven positions along the round bottom surface of the housing U, and 10 is installed by these methods A signal terminal 15 is mounted on the circuit board 3 by a bump. Figure 6 (c) shows the bottom plan view of the combined version of the SMT type and the extension type. The coaxial connector i shown in FIG. 6 (c) has ground terminals 27, 27, which protrude downward at seven positions along the circular bottom surface of the housing 11, and are mounted on the On the circuit board 3, a signal terminal 15 is mounted on the circuit board 3 by smt. Figure 6 (d) shows the bottom plan view of the combined version of the SMT type and the bump type. The coaxial connector 1 shown in Figure 6 (d) has a fresh tin bump 25 along the // V body 11 There are seven positions on the round bottom surface, and the housing Η can be grounded and shaken on the circuit board 3 by these two methods. A signal terminal 15 is mounted on the circuit board 3 by SMT. The bump type solder bump 25 and the penetration type ground terminal 38 are not limited to seven, but can be formed more. Coupling type 51 coaxial connector! The other structure is the same as the first embodiment. 17 1227581 玖, description of the invention As shown in Figure 7 (a) and (b), the bottom surface Ua of the housing u can be used as a ground terminal and connected to the circuit Ground pad on board 3. Although the coaxial connector in this embodiment uses a substantially c-shaped bottom surface Ua as a ground terminal, it is connected to a connection section (ground pad 5) of the circuit board 3. Here, Fig. 7 (a) is a bottom plan view of the SMT type using these bottom surfaces as ground terminals, and Fig. 7 (1 >) is a bottom plan view of a 4% dimer type. The coaxial connector in this embodiment connects almost the entire bottom surface 11a of the casing u to the ground pad; therefore, the bonding strength can be made stronger and the performance of the ground 10 can be improved. If a signal terminal 15 is installed by SMT to prevent the bottom from moving downward when the corresponding external connector 50 is connected to the coaxial connector, it is preferable to form a protrusion on the bottom ⑸ of the contact portion 13 contacting the circuit board 3.体 14。 Body 14. In this way, the misalignment of the contact portion 15 due to the connection and disconnection of the corresponding external connector 50 can be prevented; therefore, the contact between the contact portion 13 and the contact portion 53 of the corresponding external connector 50 can be stabilized. position. (Refer to FIG. 2 (b)) 〇 In addition to forming the convex body 14 as described above, the movement of the contact portion 13 can also be provided by the gap 20 12 between the bottom portion 13 a of the contact portion 13 and the circuit board 3. The clamping portion 30 is prevented, and the contact portion can be prevented from moving when the corresponding external connector is connected or disconnected. As shown in FIG. 9 (b), the coaxial connector M is formed as the same main body continuous portion where the clamping portion 30 projects downward from the bottom as the insulator 17.

Between plates 3. In this way, the contact position of the contact portion between the bottom portion 13a of the contact portion 13 and the contact portion 53 of the corresponding external connector 50 (refer to FIG. 2 (b)). As long as the clamping portion is accommodated in the gap 12 between the bottom portion ⑸ of the contact portion 13 and the circuit board 3 and prevents the contact portion 13 from moving, it can be broken when it is bent. In addition, the inflammation holding portion 3G may be separated from the insulator 17 and inserted into the gap 12 during connection. 10 15 20 Now, a device for cutting the connection between the coaxial connector of the present invention and the corresponding external connector 50 will be described in detail. As shown in one of Fig. 10A, the device 40A is formed with a flat plate handle 43 and a double fork pushing section 4M1 is provided at the end. This device 4GA's secrets 4i, 4i are hooked on the hooks on the upper surface of the main ground terminals 20, pulled upward (refer to Figure 10), cut off the connection between the two and move Except for the coaxial connector, the device 働 also has a double pressing section 4Mm, which is bent at a direction almost perpendicular to a flat plate handle 43.筮], the device 4c shown in Fig. 10 (c) outside the bow When the width of the circuit board 3 is known 戋 仏, ,, and ° 、 values and has a suitable shape, it is

So far, the inner-shaft connector mounted on the circuit board has been described in detail, but, of course, it is not limited to this connection n > but can be applied to the corresponding external connector. [Effects of the present invention] The coaxial connector of this & month has at least three ground terminals, which are connected to the housing and are located at or near a circle I centered in the center of the housing.

‘You have the effect of a gentleman’ can improve the high-frequency grounding performance. The _shaft connector installed on the circuit board is not easy to detach from the circuit board, and it can strengthen the installation. In addition, since almost the entire bottom surface of the housing will be engaged with the grounding mats and the coaxial connector is mounted on the circuit board and grounded on the circuit board, it has the following effects to improve high frequency The grounding performance of the coaxial connector mounted on the circuit board is not easy to detach from the circuit board, and the mounting strength can be improved. Since the main ground terminals 20 and the secondary ground terminals 21 are grounded with a large surface area, the ground pads also have a large surface area, so that they have the effect of effectively preventing the ground terminals and the ground Alignment, and the separation of the ground pads from the circuit board.
