Description

[Detailed description of the invention] This invention relates to a connector that connects wiring wires and printed circuit boards on a printed wiring board, for example, and allows the connector to be used freely even if the pitch of the pins of the connector and the other party to be connected are slightly different. The purpose is to enable insertion and connection.

A conventional connector of this type has a shape as shown in FIGS. 1 and 2, and the adjacent connecting portions a and a' are connected to each other by the shape of the connecting portion that connects them. The pitch p between a and a' is fixed, and there is a drawback that it cannot be used if there is a difference of 0.2 am in the pitch of the inserted pin.

FIG. 3 is a perspective view specifically showing the connector shown in FIG. 1 and the pins to which it connects.

a' is the connecting part, b is the connecting part, and e t e' is the connecting part a.

A wiring wire electrically connected to a', and d.

d' is a pin that is inserted into the connection plug holder (not shown) of the connection part a j a' for electrical connection, and these pins d and d' are planted on the insulating base e and printed. It is mounted on a wiring board, etc.

This invention is intended to eliminate the above-mentioned drawbacks of the prior art and will be explained by the embodiment shown in FIGS. 4 and 5.

As shown in FIG. 4, the connecting parts 1 and 1' made of synthetic resin that are adjacent to each other in parallel to each other are connected to the two connecting parts 2 and 2' that are approximately parallel to each other in the upper and lower directions. ', and these connecting parts 2, 2' have grooves 3 and grooves 3 at opposing positions in their central parts, respectively.
A notch 4 is provided on the opposite side of the root, and a groove 5 is provided on the outside of the root and a notch 6 is provided on the inside to connect each connecting portion 1, 1' and each connecting portion 2, 2'. It is provided as shown.

The state shown in FIG. 4 is the case where the pitch p between the connecting portions 1 and 1' is the widest.

FIG. 5 shows that by bending the concave groove 3 and notch 4 at the center of the connecting parts 2, 2' outward (in the vertical direction in the figure), the connecting parts 1, 1' can be closed as shown in the figure. , the pitch p can be narrowed while maintaining the parallel state.

In this way, by making use of the ingenious shape of the connecting parts 2, 2' and the elasticity of the plastic material, the connecting parts 1, 1' can maintain a parallel state and the distance between them can be expanded and contracted.
Even if there is a difference between the pitch of the connecting pins and the pitch of the connecting portion, this can be fully tolerated, and it is possible to insert and connect each other without deteriorating the electrical connection state.

In addition, although the above-mentioned embodiment described a connector consisting of a pair of connecting parts, it goes without saying that this invention can be applied to a connector configured with two or more connecting parts, and the configuration shape of the connecting parts can also be applied. is not limited to this embodiment.As described above, this invention includes a plurality of synthetic resin connecting parts 1 and 1' arranged almost parallel to each other, and these connecting parts 1 and 1'. at least a pair of substantially parallel connecting parts 2 integrally molded between the connecting parts and connecting them;
2', and in order to make the connecting parts 2, 2' bendable and expandable, a recess (in the example By providing a connector with grooves 3 and notches 4, and grooves 5 and 6), the connector can be bent freely even if the pitch of the pin to be inserted into the connection part differs depending on the manufacturer. The connector of this invention can be used for insertion connection, and since the connection parts are maintained in a parallel state, the electrical connection condition will not be deteriorated, and therefore connections with slightly different bin pitches can be used. It has the advantage of expanding the commonality of pins.

Claims (1)

[Scope of utility model registration request] The connection consists of a plurality of connecting parts made of synthetic resin that are arranged adjacent to each other in parallel to each other, and at least one pair of almost parallel connecting parts that are integrally molded between these connecting parts and connect them. A connector characterized in that a concave portion is provided in the intermediate portion of the connecting portion and the root portion between the connecting portion and the connecting portion so that the portion can be bent and expanded.
