Description

  The present invention relates to a short-circuit connection cap that forms a closed circuit in a non-fitted state of an object to be connected.

  There is a case where a connection object such as an expansion board is connected to a connector fixed to the board to expand the function of the electric device. Such a connector can be used even in a non-fitted state of the connection object, or the connection object in the fitting state may be removed and another connection object may be fitted. In addition, this connector includes a plurality of terminals arranged to face each other, and in a non-fitted state where the connection object is not connected to the connector, the terminals are brought into conductive contact to form a closed circuit that is short-circuited. When the connection object is fitted, the closed circuit is opened, and a new function can be added by forming another circuit by conducting contact with the terminal (for example, Patent Document 1).

JP-A-53-133790

  The connector has a plurality of terminals each having a contact portion for connection with a connection object and an elastic arm that elastically supports the contact portion, and these are arranged in a pair so as to face each other. The contact portions of these terminals are supported by elastic arms so as to protrude toward the other terminal side, and in a non-fitted state with the connection object, they contact each other to form a closed circuit. And at the time of a fitting operation | work, a connection target presses a terminal, a connection target enters between contact parts, and another circuit is formed by conducting contact with a connection target in the said contact part. Therefore, it is necessary to provide the terminal with a structure for short-circuit connection, such as a pressed part or an elastic arm pressed by the connection object. Therefore, there is a problem that it is necessary to provide the connector with a terminal having a complicated structure as compared with a normal terminal having only a contact portion that is in conductive contact with the connection object.

  The present invention has been made to solve the above problems. That is, an object of the present invention is to provide a short-circuit connection cap that can easily form a closed circuit in a non-fitted state of a connection object even for a connector that does not have a structure for short-circuit connection.

The present invention that achieves the above object is configured as follows.
That is, the present invention has a mounting portion that holds a housing of a connector that includes a plurality of connector terminals, and a cover portion that is provided at an insertion port of a connection object of the connector provided in the housing, the cover portion being A short-circuit connection cap including a short-circuit connection terminal that is in conductive contact with the one connector terminal and the other connector terminal is provided.

  By providing a short-circuit connection terminal that is in conductive contact with multiple connector terminals at the same time, a closed circuit can be formed in a non-fitted state with a connection object by simply mounting the connector terminal without a connector terminal having a structure for short-circuit connection. It can be set as the cap for short circuit connection to form. Further, according to the present invention, since the short-circuit connection cap can be attached to the connector simply by holding the housing with the mounting portion, a closed circuit can be easily formed.

  The cover part of the present invention may have an insertion wall inserted into the insertion port of the housing, and the insertion wall may have a holding part for holding the short-circuit connection terminal.

  By doing so, the insertion wall can reinforce the short-circuit connection terminal inserted in the insertion port of the housing. Therefore, even if the short-circuit connection terminal is pressed from the connector terminal, the short-circuit connection terminal can be held so as not to be separated from the connector terminal.

  The short-circuit connection terminal of the present invention may have a contact portion that is in electrical contact with the connector terminal on the plate surface of the flat metal plate.

  By carrying out like this, compared with the case where a contact part is provided in plate | board thickness surfaces (surface orthogonal to a plate surface), such as a fracture surface of a metal plate, a contact part of a wider area can be provided. Therefore, for example, even when the connector terminal is misaligned with respect to the short-circuit connection terminal or the connector terminal is provided at an unintended position due to a manufacturing error of the connector, such misalignment over a wide plate surface, etc. Therefore, the contact portion can maintain the conductive contact.

  The terminal for short-circuit connection according to the present invention may have a first contact portion and a second contact portion that are in conductive contact with two connector terminals adjacent in the arrangement direction.

  In this way, even with respect to a connector having a plurality of connector terminals arranged so as to be in conductive contact by being sandwiched from both sides with respect to the connection object, it is arranged so as to be in conductive contact only from one side. Even a connector having a plurality of connector terminals can be mounted. Further, even when the connector terminals are arranged in a complicated manner such as a staggered arrangement, they can be mounted. Therefore, a highly versatile short-circuit connection cap can be obtained.

  The cover part of the present invention may cover the insertion port.

  By doing so, it is possible to prevent foreign matter from entering the fitting chamber of the connector. Therefore, it is possible to achieve both the formation of a closed circuit in a non-fitted state with the connection object and the suppression of the decrease in connection reliability due to the foreign matter coming into contact with the connector terminal.

  The cover part of the present invention may have a projecting part projecting outward from the housing.

  By carrying out like this, it can remove from a connector easily by hooking a finger | toe on a protrusion part. Therefore, it is possible to provide a short-circuit connection cap that can be easily attached and detached.

  According to the short-circuit connection cap of the present invention, it is possible to easily form a closed circuit between the connector terminal and the substrate without providing a special terminal in a non-fitted state of the connection object.

  Hereinafter, a preferred embodiment of the short-circuit connection cap of the present invention will be described with reference to the drawings. The short-circuit connection cap 1 of this embodiment is used by being attached to a connector 2. In this specification, the short direction connection cap 1 will be described with the width direction as the X direction, the front-rear direction as the Y direction, and the height direction of the short connection cap as the Z direction. In the state where each short-circuit connection cap 1 is attached to the connector 2, the connector 2 side in the height direction Z is referred to as “lower side”, and the short-circuit connection cap 1 side is described as “upper side”. However, these descriptions do not limit the method of using the short-circuit connection cap 1.

Embodiment [FIGS. 1-14]:
[Cap for short-circuit connection]
The short-circuit connection cap 1 includes a cap housing 5 and a short-circuit connection terminal 4. The short-circuit connection terminal 4 is in conductive contact with the connector terminal 3 of the connector 2 to form a closed circuit.

[Cap housing]
The cap housing 5 is made of an insulating resin and has a substantially rectangular parallelepiped shape. Moreover, the cap housing 5 has the cover part 6 and the mounting part 7, as shown in FIGS.

  The cover portion 6 is provided so as to cover the insertion port 8a3 of the connector housing 8 in a state where the short-circuit connection cap 1 is attached to the connector 2. The cover part 6 has projecting parts 6a that project further along the width direction X than the side wall parts 7c of the mounting part 7 to be described later on both ends in the width direction X. When the short-circuit connection cap 1 is attached to the connector 2 and then removed from the connector 2, the removal work can be easily performed by hooking a finger or the like on the protruding portion 6a. Therefore, the attachment work of the connection object to the connector 1 can be easily performed.

  Moreover, since the cap housing 5 has the cover part 6, even if it is the state which removed the connection target object from the connector 2, it can prevent a foreign material from entering into the fitting chamber 8a2. Therefore, a decrease in connection reliability of the connector 2 can be suppressed. Moreover, the cover part 6 has the flat adsorption | suction part 6b between protrusion part 6a, 6a. Therefore, it is possible to provide the short-circuit connection cap 1 that can cope with automatic mounting.

  The mounting portion 7 extends downward from the cover portion 6 and includes an insertion wall 7d, a front wall portion 7a, a rear wall portion 7b, and a side wall portion 7c.

  7 d of insertion walls are extended in the lower surface of the cover part 6 from the approximate center in the width direction X and the front-back direction Y toward the lower side. The insertion wall 7d is plate-shaped and has a plate surface along the XZ plane. On the rear side of the insertion wall 7d and at one end in the width direction X, a holding portion 7d1 for the short-circuit connection terminal 4 is provided. By adopting such a configuration, the insertion wall 7d can reinforce the short-circuit connection terminal 4. Therefore, even if the insertion terminal 7 is strongly pressed from the connector terminal 3, the short-circuit connection terminal 4 is not deformed plastically and is electrically connected to the connector terminal 3. You can keep in touch.

  The front wall 7a is provided on the front side of the insertion wall 7d, and the rear wall 7b is provided on the rear side of the insertion wall 7d. And each has a plate surface along the XZ plane.

  One side wall part 7c is arrange | positioned at the both ends in the width direction X of the front wall part 7a and the rear wall part 7b, and has connected them. A locking portion 7 c 1 along the height direction Z is provided at a substantially center in the front-rear direction Y of the side wall portion 7 c and is locked to the connector housing 8. Thus, the short-circuit connection cap 1 can be easily attached to the connector 2.

[Short-circuit connection terminal]
The short-circuit connection terminal 4 is fixed to the rear surface of the insertion wall 7d. The short-circuit connection terminal 4 is a conductive metal plate having a substantially trapezoidal cross section, and is provided by punching and bending the metal plate. And as shown in FIG. 9, FIG. 10, it has the fixing | fixed part 4b with respect to the insertion wall 7d of the cap housing 5, the guide part 4c, and the contact part 4a.

  One fixing portion 4b is provided above and below the contact portion 4a, and is fixed to the holding portion 7d1 of the insertion wall 7d. By having such a fixing portion 4b, even if the connector terminal 3 of the connector 2 is pressed against and contacts the contact portion 4a, the short-circuit connection terminal 4 is securely fixed so as not to be detached from the cap housing 5. Yes.

  The guide part 4c is connected to the fixed part 4b and is provided to be inclined toward the upper side and the rear side. Thereby, the connector terminal 3 is guided by the guide part 4c, and can reach the contact part 4a smoothly.

  The contact portion 4a has a flat plate shape and has a plate surface along the XZ plane. In the width direction X, it has such a length that it can contact the connector terminals 3A and 3B arranged adjacent to each other. The contact portion 4a is connected to the guide portion 4c, and is provided so as to protrude toward the terminal portion 3c side of the connector terminal 3 in a state where the contact portion 4a is attached to the connector 2 from the insertion wall 7d. By doing so, the connector terminal 3 can be easily contacted. Moreover, since the contact pressure with respect to the connector terminal 3 can be raised simultaneously, it can carry out the conductive contact with the terminal part 3c more reliably. Thus, the first contact portion 4a1 provided in the contact portion 4a is in conductive contact with the terminal portion 3c of the connector terminal 3A, and the second contact portion 4a2 is in conductive contact with the terminal portion 3c of the connector terminal 3B. Since the contact portion 4a has such contact portions 4a1 and 4a2 on a flat plate surface, the terminal portion 3c of the connector terminal 3 is displaced with respect to the short-circuit connection terminal 4 or is in conductive contact at an unintended position. Even so, the wide contact portion 4a allows the displacement and the like, and can maintain the conductive contact.

〔connector〕
The connector 2 to which the short-circuit connection cap 1 of this embodiment is attached includes a connector housing 8 and a plurality of connector terminals 3 as shown in FIGS. The connector housing 8 is made of an insulating resin and has a substantially box shape having a connector main body 8a having a fitting chamber 8a2 and a fixing portion 8b for the substrate P. The connector main body 8a has a terminal accommodating portion 8a1, and a plurality of terminal accommodating portions 8a1 are arranged in parallel along the width direction X. One connector terminal 3 is accommodated and held in the terminal accommodating portion 8a1. An insertion port 8a3 for a connection object (not shown) communicating with the fitting chamber 8a2 is disposed on the upper surface of the connector body 8a.

  The connector terminal 3 has a board connecting part 3a, a base end part 3b, and a terminal part 3c. The board connecting portion 3a is soldered to the board. The base end portion 3 b is connected to the board connecting portion 3 a and is fixed to the connector housing 8. The terminal portion 3c extends upward from the base end portion 3b, and is in electrical contact with the connection object in the fitting chamber 8a2. In the present embodiment, as the “connector terminal”, the terminal portion 3 c includes the front terminal 3 c 1 and the rear terminal 3 c 2, and the connector terminal 3 having high connection reliability is exemplified. However, even if the short-circuit connection cap 1 of this embodiment is a connector other than the connector 2 as long as it is a connector having a plurality of connector terminals 3, it can be mounted.

〔how to use〕
The short-circuit connection cap 1 is aligned with the insertion port 8a3 of the connector 2. The front wall portion 7 a, the rear wall portion 7 b, and the side wall portion 7 c of the short-circuit connection cap 1 are arranged along the outer surface of the connector main body 8 a of the connector 2. By attaching the short-circuit connection cap 1 to the connector 2 as it is, the insertion wall 7 d and the short-circuit connection terminal 4 enter the fitting chamber 8 a 2 of the connector 2.

  At that time, two connector terminals 3 provided on one end side in the width direction X and arranged adjacent to each other are in contact with the guide portion 4c and guided to the contact portion 4a of the short-circuit connection terminal 4 (FIG. 13). , FIG. 14). Thereafter, the insertion wall 7d of the short-circuit connection cap 1 is sufficiently inserted into the fitting chamber 8a2 of the connector 2, and the locking portion 7c1 of the side wall portion 7c is provided in the connector housing 8 of the connector 2 ( The mounting operation is completed by locking with respect to (not shown). Thus, the short-circuit connection terminal 4 is brought into conductive contact with the two connector terminals 3 to form a closed circuit connecting the substrate P, one connector terminal 3A, the short-circuit connection terminal 4 and the other connector terminal 3B. it can. Thereafter, when the connector 2 and the connection object are fitted, the short-circuit connection cap 1 is removed from the connector 2. By doing so, the connector terminal 3 and the short-circuit connection terminal 4 are separated from each other, and the closed circuit can be opened.

  Here, the connector terminals 3 are arranged in a staggered manner like the connector 1, and the connector terminals 3 facing each other via the fitting chamber 8a2 are displaced from each other in the arrangement direction (the width direction X in this embodiment). In such a case, a short-circuit connection terminal having a complicated three-dimensional shape is necessary in order to electrically connect the opposing connector terminals 3 to each other. In this case, it is difficult to manufacture the short-circuit connection terminal, and more metal material is required. In contrast, the short-circuit connection terminal of the present embodiment has a plate surface along the XZ plane as described above, and two adjacent connector terminals 3A arranged along the arrangement direction of the connector terminals 3. , 3B is in conductive contact. Therefore, the connector terminal 3A, 3B is conductively connected to form a closed circuit only by having a plate surface having a length that allows the contact portion 4a to be in conductive contact with the adjacent connector terminals 3A, 3B in the width direction X. Can do. By using such a short-circuit connection terminal 4, in addition to the connector 1, for example, FPC (Flexible printed circuits), FFC (Flexible flat cable), and the like are connectors to be connected, and a plurality of connector terminals 3 are to be connected. Even if it is arranged so as to be in conductive contact only from one side with respect to an object, the closed circuit cap 1 of the present embodiment can be attached to form a closed circuit. Thus, according to this embodiment, it can be set as the cap 1 for short circuit connection with higher versatility.

  Thus, according to the short-circuit connection cap 1 of the present embodiment, a closed circuit can be easily formed even for the connector 2 that does not include a connector terminal having a complicated shape for forming a closed circuit.

Variation of the embodiment:
The short-circuit connection cap 1 of the present embodiment has been described as an example having the short-circuit connection terminal 4 that is in conductive contact with the connector terminals 3A and 3B arranged adjacent to each other. On the other hand, it can also be set as the short-circuit connection terminal 4 which carries out conductive contact with the connector terminals 3A and 3B arranged oppositely via the fitting chamber 8a2. Moreover, it can also be set as the short circuit connection terminal 4 which carries out conductive contact with the connector terminal 3A and 3B which adjoins through the connector terminal 3 and the other structure with which the connector 1 is provided.
