Description

  The present invention relates to a connector that is attached to an end portion of a board on which an electronic component such as an LED is mounted and connects the boards.

  Conventionally, when a plurality of boards are connected to each other so that the mounting surfaces of electronic components and the like are on the same plane, a male connector and a female connector are attached to the end portions of the boards, respectively. The boards are connected to each other by fitting the side connector and the female side connector (for example, see Patent Document 1).

Utility Model Registration No. 3092610

  However, when connecting the connectors attached to the ends of the boards as described above, it is difficult to directly grip and fit the connectors, so the connectors on each board are connected while holding each board. There is a need. For this reason, a reaction force at the time of connector fitting is applied to the joint portion between the connector terminal and the substrate, and there is a problem in that the solder at the joint portion is easily peeled off and the joint strength is easily lowered.

  The present invention has been made in view of the above problems, and the object of the present invention is to provide a reaction force at the time of connector fitting between the terminal and the board even when connected to the mating connector in a state of being attached to the board. It is an object of the present invention to provide a connector that can be easily connected without adding to the joint portion.

In order to achieve the above object, the present invention provides a connector body that is attached to an end portion of a board and is connected to a mating connector attached to an end portion of another board to connect the boards to each other. provided so as to be movable in the direction, a slide member movable externally operated, held by the slide member, and a pair of male terminals and female terminals connected to the substrate, the same configuration of the mating connector and the connector body The ends of the connectors are brought into contact with each other , and the sliding members of each connector are moved toward each other connector so that the male and female terminals of each connector protrude from one end of the connector body and are connected to each other .

As a result, the male terminal and the female terminal protrude from one end of the connector main body and the female terminal and the male terminal of the mating connector project by moving one end of the connector main body to the mating connector and moving the slide member toward the mating connector. Therefore, even when connecting to the mating connector while attached to the board, there is no need to hold the board to fit the connectors together, and the reaction force when the connector is fitted is a male terminal and a female terminal. It does not add to the junction between the substrate and the substrate. In this case, the male terminal and the female terminal of each connector are connected to each other by abutting one end of the mating connector and the connector body having the same configuration, so the boards can be connected with one type of connector. There is no need to use two types of connectors consisting of a male connector and a female connector.

According to the present invention, even when connecting to the mating connector in a state of being attached to the board, it is not necessary to hold the board and fit the connectors together, so that the connection work can be easily performed. At that time, since the reaction force at the time of connector fitting is not applied to the joint between the terminal and the board, it is possible to prevent the peeling of the joint with the board and the decrease in the joint strength, and to improve the connection reliability. You can also plan. In this case, since it is possible to connect the boards with one type of connector, there is no need to use two types of connectors consisting of a male connector and a female connector. For example, three or more boards are attached by attaching connectors to both ends of the board. Even when connected in series, connectors having the same configuration can be used, and the connectors used for connecting the substrates can be shared.

  In the connector configured as described above, the locking portion 3e of the second slide member 3 is locked in the second locking hole 1b on the rear side of the connector body 1 as shown in FIG. The first and second slide members 2 and 3 are locked in a state where they are moved rearward of the connector main body 1. In that case, the male terminal 4 and the female terminal part 2b (female terminal 5) are accommodated in the connector body 1 so as not to protrude outside from the front end of the connector body 1. Further, when the operation portion 3b of the second slide member 3 is pressed forward and the first and second slide members 2 and 3 are moved forward, the male terminal 4 and the female terminal as shown in FIG. The portion 2b (female terminal 5) protrudes from the front end of the connector body 1 to the outside, and the locking portion 3e of the second slide member 3 locks in the first locking hole 1a in the front of the connector body 1, The first and second slide members 2 and 3 are locked in a state where they are moved forward of the connector body 1. At that time, the movement of the slide members 2 and 3 with respect to the connecting portions 4e and 5e of the male terminal 4 and the female terminal 5 is performed by deforming the movable portions 4d and 5d to extend in the front-rear direction as shown in FIG. Absorbed.

  In the connector, the connection portions 4e and 5e of the male terminal 4 and the female terminal 5 and the fixing members 1c of the connector body 1 are soldered to the conductive pattern (not shown) of the substrate 10, respectively, as shown in FIGS. As shown in FIG. 2, the substrates 10 are connected to each other by being attached to the end of the substrate 10 and connected to a mating connector of the same configuration attached to the other substrate 10. In this case, as shown in FIG. 17, when the front ends of the connector bodies 1 of each connector body are butted together, the male terminal 4 of one connector and the female terminal portion 2b of the other connector face each other, and the female terminal of one connector Since the portion 2b and the male terminal 4 of the other connector face each other, as shown in FIG. 18, the operation portion 3b of the second slide member 3 of each connector is pressed, and the first and second slide members 2 and 3 are moved. Move them closer together. Thus, the male terminal 4 of one connector is inserted into the insertion port 2c of the female terminal portion 2b of the other connector and connected to the female terminal 5 of the other connector, and the female terminal portion 2b of one connector is inserted. The male terminal 4 of the other connector is inserted into the opening 2c and connected to the female terminal 5 of one connector. In other words, since the connectors are fitted together by moving the first and second slide members 2 and 3 of each connector, it is not necessary to hold the board 10 and fit the connectors together. At that time, since the front ends of the connector main body 1 of each connector are abutted with each other, for example, the operation portion 3b of each connector can be easily pressed between the thumb and index finger of one hand, and the first and first The pressing force for moving the two slide members 2 and 3 is not applied to the substrate 10 from the connector body 1.

  As described above, according to the present embodiment, one end of the connector body 1 is abutted with the mating connector, and the first and second slide members 2 and 3 are moved toward the mating connector. Since the female terminal 5 protrudes from one end of the connector body 1 and is connected to the female terminal 5 and the male terminal 4 of the mating connector, it is not necessary to hold the respective boards 10 and connect the connectors to each other. Can be easily performed. At that time, since the reaction force at the time of connector fitting is not applied to the joint portion between the male terminal 4 and the female terminal 5 and the substrate 10, the peeling of the solder at the joint portion with the substrate 10 and the decrease in the joint strength are prevented. It is possible to improve connection reliability.

  In addition, since the mating connector of the same configuration and one end of the connector body 1 are butted together and the male terminal 4 and the female terminal 5 of each connector are connected to each other, the substrates 10 can be connected to each other with one type of connector. it can. This eliminates the need to use two types of connectors consisting of a male connector and a female connector. For example, even when three or more substrates 10 are connected in series by attaching connectors to both ends of the substrate 10, all connectors having the same configuration are used. It is possible to use a common connector for connection between the substrates 10.

  Furthermore, since the movable portions 4d and 5d that can be deformed in the moving direction of the slide members 2 and 3 are provided between the contact portions 4a and 5a of the male terminal 4 and the female terminal 5 and the connection portions 4e and 5e, the substrate The movement of the contact portions 4a and 5a with respect to the connection portions 4e and 5e fixed to 10 can be absorbed by the deformation of the movable portions 4d and 5d, which is extremely advantageous for the configuration in which the slide members 2 and 3 are moved.

  Further, when the slide members 2 and 3 move to a position where the male terminal 4 and the female terminal 5 are connected to the female terminal 5 and the male terminal 4 of the mating connector, the locking portion 3e of the second slide member 3 is connected to the connector body. 1 so that the slide members 2 and 3 are locked with respect to the connector main body 1 so that the slide members 2 and 3 are connected to the connector main body after the connector is fitted. It is possible to reliably maintain the connection state between the connectors without moving backward.

  In the above embodiment, the slide member is formed by the first and second slide members 2 and 3 which are separate from each other. However, a slide member made of an integral part may be used.

  In the above embodiment, the movement of the slide members 2 and 3 with respect to the connection portions 4e and 5e of the male terminal 4 and the female terminal 5 is absorbed by the deformation of the movable portions 4d and 5d. The terminals divided on the slide members 2 and 3 side and the substrate 10 side are connected by a flexible conductor such as a lead wire, or the divided terminals slide while contacting each other. By doing so, you may make it absorb the movement of each slide member 2 and 3 with respect to the terminal by the side of the board | substrate 10. FIG.
