Abstract

PURPOSE:To reduce the number of structural parts of a connector, and also to make an interconnection between circuit substrates simultaneously with mounting the connector onto each of the circuit substrates by planting female and male terminals respectively in their relevant block bodies, and then making such structure that the two block bodies can be united with each other via the relevant terminals. CONSTITUTION:Each of male terminals 5 is arranged across an engaging block 8 and a fixed block 9 both of which construct a male-side block 2, and contact portions 10 are respectively mounted into the block 8 while terminal legs 11 are respectively mounted into the block 9, and the contact portions and the terminal legs are conjoined via bent portions 12. Each of fork terminals 7 mounted into an engaging body is connected in a cross shape to the male terminal 5, and the male terminal can slide even if printed circuit boards 17a, 17b are interconnected in proximity to or at a distance from each other via a connector so that the terminal 5 and the terminal 7 may always keep mutual contact conditions. In this manner, the two substrates can be interconnected simultaneously by mounting the connector onto each of the circuit substrates so as to cope with the dimensional dislocation of the connector due to an error in installing it, and further so as to reduce the number of structural parts of the connector.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a circuit board connector capable of horizontally connecting a pair of circuit boards.

2. Prior Art The structure of a conventional connector of this type is shown in FIGS. 5 and 6.

A conventional connector of this kind consists of three or more block bodies, as shown in FIG. 5, in which 51 is a plug pin body and 52 is a socket housing. circuit board 53
When connecting horizontally between A and another printed circuit board 53b, the plug pin body 51 is fixed to the two circuit boards 53a and 53b with solder, and inserted into the connection terminal holes provided at both ends of the socket housing 52. This purpose is achieved by inserting and mounting the plug pin bodies 54 implanted on the plug bottle body 51, respectively. FIG. 6 shows a plug pin body 51 and a socket housing 52 having a different shape from those in FIG.

Problems to be Solved by the Invention However, with the conventional connector having the above configuration, it is necessary to insert the socket housing after fixing the two printed circuit boards at the required positions, which requires a long process. In addition to the large number of connectors, it is difficult to connect them automatically, and the number of parts that make up the connector is large, making it difficult to assemble and increasing costs.

The present invention solves these conventional problems,
It is an object of the present invention to provide an excellent connector that has a small number of component parts and that allows connection between boards at the same time as mounting the connector on a circuit board.

Means for Solving the Problems In order to achieve the above object, the present invention provides a female side block in which a terminal made of a thin metal plate formed into a fork shape at one end and connected to one circuit board at the other end is implanted. and a male side block body in which a terminal made of an elastic U-shaped thin metal plate is implanted, one end of which is connected to the fork-shaped portion of the terminal and the other end of which is connected to the other circuit board, The structure is such that two block bodies can be integrally connected through their terminals.

According to the present invention, since the female terminal and the male terminal are implanted in each block body, the number of parts can be reduced, and at the same time when the connector is attached to the circuit board, two It is possible to connect several circuit boards.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 4. FIG. 1 shows 3 according to one embodiment of the present invention.
FIG. 2 is a perspective view of a connector assembly 1 of the connector assembly 1, which is composed of a male side block body 2 a female side block body 3;
The male block body 2 is composed of a male insulator 4 and a male terminal 5, and the female block body 3 is composed of a female insulator 6 and one or more fork terminals 7. Fig. 2 is a partially fragmented perspective view of the female block body 3, Fig. 3 is a sectional view of the male block body 2 and female block body 3 in a fitted state, and Fig. 4 is a male block body. 2 and a female block body 3 are fitted together. FIG. In FIG. 1, the male terminal 5 is inserted between the fitting block body 8 and the fixed block body 9 that constitute the male block body 2, and one end on the opposite side of the contact portion 10 is inserted into the fitting block body 8. , one end on the opposite side of the terminal leg 11 is attached to the fixed block body 9. The bent portion 12 connecting one end on the opposite side of the contact portion 10 and one end on the opposite side of the terminal leg 11 is formed by two thin partitions 13 each provided between the fitting flock body 8 and the fixed block body 9. The partition portions 13 are provided in parallel to each other, and the purpose of this partition portion 13 is to connect the fitting block body 8 and the fixed block body 9, and to insulate the male terminals 5 from each other. It does not restrict movement. Further, in the female block body 3, a large tapered portion 15 is provided at the upper edge of the terminal insertion opening 14, so that the tip of the contact portion 10 of the male terminal 5 can be easily inserted. Next, in FIG. 2, a fork terminal 7 having a fork-shaped contact portion 16 is implanted in the female block body 3 so as to connect with the male terminal 5 in a cross shape when the male terminal 5 is inserted. the direction in which the male terminal 5 is inserted into the terminal insertion opening 14;
That is, the cross-shaped longitudinal opening is longer than the width of the contact portion 10 of the male terminal 5, and furthermore, the cross-shaped opening in the longitudinal direction is longer than the width of the contact portion 10 of the male terminal 5.
By opening one side, the male terminal 5 can slide in the direction of the arrow as shown in FIG. 3, even if the two printed circuit boards 17a and 17b are connected closely. Since the connector can be moved with ease, no excessive force is applied to the connector structure. Furthermore, as described above, even when the printed circuit boards 17a and 17b are connected slightly apart in the connection direction, since the contact portion 10 of the male terminal 5 is provided wider than the female contact portion 16, the male side terminal 5 and the female terminal 7 always maintain a contact state, and the electrical connection is never broken. Next, as shown in Figure 4,
When mating the connector, if the male block body 2 and the female block body 3 become blurred in the direction of the arrow, that is, in the direction of 90 degrees with respect to the connection direction of the printed circuit board 17a17b, the male terminal 5 may be bent. The portion 12 and the partition portion 13 have flexibility and absorb stress caused by the above-mentioned deviation.
No excessive force is applied to the printed circuit board, connector structure, terminals, etc.

Effects of the Invention As is clear from the embodiments described above, according to the connector of the present invention, the connector is composed of two block bodies each having a terminal embedded therein, and the connector can be mounted on two printed circuit boards or the like at the same time. Two circuit boards can be connected, and dimensional deviations due to installation errors between the two circuit boards can be absorbed, making it compatible with automatic assembly.Furthermore, costs can be reduced by reducing the number of parts that make up the connector. This will give you the effect that you can do it.
