[Problem that the idea aims to solve]

By the way, such conventional floating type connectors are installed in separate instru- ments. Since the insulator is manufactured using a Two types of molds are required, which increases the cost of the molds and the overall cost of the product. There are issues such as: Also, if the two insulators have different shapes, one If there is a shortage of insulators, it will be impossible to assemble the connector, which will hinder work efficiency. Was.

0004 Furthermore, the contacts used in this floating type connector are The flexible part has flexibility when floating, and is designed to be flexible when press-fitted. In order to have a certain degree of resistance, the float floats in the X and Y directions are The lining was a little stiff.

[0005] Therefore, the challenge of this invention is to create a flow that is low cost and has excellent floating properties. Our goal is to provide connecting connectors.

[0006]

[Means to solve the problem]

According to the present invention, a pair of insulators and a the pair of insulators includes a flat contact that intersects the contact. Floating connectors that are engaged with each other for relative movement in a plane In this case, the above pair of insulators have the same shape at least when assembled. and each of the pair of insulators is fitted with the contact. A main body portion having a bottom portion formed with an insertion hole for insertion and retention, and a wall portion erected from the bottom portion. , and an insulator wall portion hanging from the main body portion, The data wall portion locks and accommodates the main body portion in a relatively movable state, and The contact is inserted between the insertion hole of one insulator and the other insulator, leaving the flexible part. The flexible part is inserted into and held in the insertion hole of the insulator, respectively, and the flexible part is The floor is configured such that the contact press-fitting portion is separated from the contact press-fitting portion. You can get a connecting connector.

【Example】

1-3 illustrate a floating connector according to an embodiment of the present invention. This flow In the mating connector, the insulator connects the main body part 1, which is the mated part, and this It has a shape that allows the main body part 1 to be accommodated on the lower side so as to be movable in the X direction and the Y direction shown in FIG. It consists of four wall parts 4 that define a recess. The main body part 1 has a rectangular bottom part 1a and the bottom part It consists of four walls 1b standing upright from the top. Contact 2 is attached to the bottom 1a. An insertion hole 7 for insertion is formed. Each wall portion 1b has a loose fitting shape in an engagement hole 5 which will be described later. An engaging protrusion 3 is formed that engages in this state. At the bottom of this main body part 1, there are The separated wall portions 4 are integrally molded.

[0008] The wall portion 4 is located at a position corresponding to the engaging protrusion 3 of the main body portion 1 when assembled. Engagement holes 5 are formed in the respective positions. The size of this engagement hole 5 is such that it accommodates the engagement protrusion 3. and when the engaging protrusion 3 is floating, the inside of the engaging hole 5 is viewed in the X direction shown in FIG. It is necessary that the dimensions are such that it can be moved in the Y direction.

[0009] Figure 4 shows the contact 2 used in the floating connector shown in Figures 1 to 3. FIG. This contact 2 has a tongue-shaped connection side part (connection side tongue part) 10. and a tongue-shaped fitting press-fitting side part (fitting press-fitting side tongue part) 11, which are connected. They are integrally connected at part 8. This connecting part 8 gives flexibility This is the part for. The connection side tongue piece 10 is provided with a connection part parallel to and apart from the connection part. A tongue piece part 9 is formed which is separated from the fitting press-fitting side tongue piece part 11.

0010 Next, we will explain how to assemble a floating connector using each of these parts. . The above insulators are stacked facing in the same direction. In addition, these inputs When the Schreiters are stacked and combined, both are in the X direction and It is relatively movable in the Y direction. That is, as can be seen from Figure 3(b) , the main body part 1 which becomes the lower insulator is a wall surface which becomes part of the upper insulator. It is adapted to move within the section 4 to some extent in the pitch direction and/or width direction.

[0011] The contact 2 is press-fitted from the wire connection side of the insulator and fixed. Main body part 1 Since the upper and lower insulators have the same size, the width of the insertion hole 7 formed in the bottom 1a of the If the fitting side press-fitting side portion 11 is allowed to pass through, press-fitting will not be possible. this Therefore, the contact size is larger than that required for inserting the contact into one side of the insertion hole 7. The insertion portion 6 with a large size is formed in advance. Then, the dimensions of the insertion hole 7 can be adjusted so that the contact It can be set to the dimensions that will be press-fitted. That is, as shown in FIG. 5(a), Pass the fitting side press-fit part 11 of the contact through the insertion part 6 of the lower insulator and insert it into the upper part. It is located just in front of the insertion part 6 of the insulator. With this predetermined dimension inserted , the contact 2 is forcibly moved toward the insertion hole 7 as shown in FIG. 5(b). child After that, it is further pushed in the insertion direction as shown in FIG. 5(c). Then, the contour The actuator 2 is press-fitted into the insertion hole 7.

0012 Push contact 2 into the insulator in the above condition, but at this time, the flange The flexible connecting part 8 is bent, and the tongue pieces 9, which are press-fitting parts on both sides, are on the fitting side. It abuts against the press-fitting part 11, and the fitting side and the wire connection side can be press-fitted at the same time.

[0013] As above, after assembling the insulator and assembling contact 2, Break off the excess wall part 4 of the insulator (the shaded part in Figure 2) Remove by cutting or cutting.

[0014]

[Effect of the idea]

As explained above, according to the present invention, two insulators of one type of shape are used. Since they can be stacked one on top of the other, only one type of mold is needed for insulator molding. , it is possible to achieve a significant reduction in manufacturing costs. Also, the same applies when assembling. Since parts of one shape are used, work may be delayed due to a shortage of one part. I've never been.

[0015] In addition, in the floating connector of this invention, the connector can be made flexible. (connection part 8) and press-fitting part (tongue part 9) are separated, flexibility is improved. The height increases and the floating becomes soft. Therefore, when installing the wiring section and the connector, The load on the connected board is reduced, and the performance as a floating connector is improved. It is possible to improve the quality of the final product.
