Embodiments of the present invention will be described below with reference to the drawings. The present invention is roughly divided into a plurality of (three in the drawing) elongated rectangular parallelepiped supports 1 shown in FIG. 1 and a plurality of terminal pins 2 arranged in a row on each of the supports. As shown in FIGS. 2 and 3, the storage case 3 is configured to store the plurality of supports in a joined state.

First, the support 1 will be described. The shape of one support 1 is a rectangular parallelepiped made of synthetic resin as shown in FIG. The portions 11 are alternately formed in the longitudinal direction, and the concave portions 10 on one side face have a symmetrical positional relationship with the convex portions 11 on the other side face. The lateral widths of the concave portion 10 and the convex portion 11 do not need to be all the same, but at least the concave portion 10 and the convex portion 11 formed in a symmetrical positional relationship on both sides of the support have the same width. It is necessary to be.

As shown in FIG. 5, a locking hole 101 having a square front shape is formed at the center of the concave portion 10 of the support body 1, and a square front shape is formed at the center of the convex portion 11. A locking projection 111 is formed. The locking projection 111
The engaging protrusion 101 can be fitted into the engaging hole 101 of the concave portion 10 of the other support body 1 that is adjacently joined in a surface contact state by pressing, and the outer shape of the engaging protrusion and the inner shape of the engaging hole are fitted. It is molded into the same shape that can be combined. Specifically, the locking projection 11
1 has a front surface having an inclined surface 111a formed toward the lower surface. Due to the inclined surface, both side surfaces 111b have a trapezoidal shape rising vertically from the front end surface of the projection 11, and the upper surface 111c Has a planar shape that rises vertically from the front end face of the projection. The locking hole 101 has an inclined surface 111a formed on the inclined surface 111a of the locking projection 111 at the same inclination angle toward the lower surface, and the ceiling surface and both inner side surfaces 101b of the locking hole are locked. The projection 11 has a shape capable of making surface contact with both side surfaces 111b, 111b and the upper surface 111c.

Therefore, when the supports 1 are in contact with and joined to other adjacent supports, the concave portions 10 and the convex portions 1
In the state in which 1 and 1 are fitted, simultaneously, the locking hole 101 and the locking projection 111 are also in a state of being engaged.

Next, the terminal pins 2 will be described. The plurality of terminal pins 2 penetrate the support 1 vertically and are arranged in a row as shown in FIG. As is well known, there are both male and female types of terminal pins 2. The male type terminal pins are simply long and flat, but the shape of the female type terminal pins is shown in FIG. As shown, a bent portion is formed from the intermediate portion 21 to the front end portion 22, and the rear end portion has forked portions 23, 23. FIG. 7 shows a state in which the female terminal pins 2 are pressed into the support 1.

Next, the storage case 3 will be described.
As shown in FIGS. 2 and 3, concave portions 31 and convex portions 32 into which the concave portions 10 and the convex portions 11 of the support body 1 can be fitted are formed on both inner wall surfaces. A locking hole 33 for locking the locking projection 111 on the side surface of the support 1 is formed,
Above the locking hole at the opening edge of the storage case, a guide inclined surface 31a for facilitating locking of the locking projection is formed. In the lower half of the inside of the storage case 3, a forked portion 2 of the terminal pin 2 is formed in a lattice shape.
A storage part 34 for inserting the storage case 3 or 23 is formed. At both ends of the storage case, mounting holes 35,
35 are formed.

Therefore, a method for manufacturing and assembling the connector according to the present invention will be described.

The terminal pins 2 are press-fitted (or inserted) in a row in one support 1 to complete one support as shown in FIG. 4, and when the press-fitting of the terminal pins is completed, a plurality of support pins are formed. The body is fitted while pressing the concave portions 10 and the convex portions 11 on the mutual side surfaces from the outside, and
1 and the locking holes 101 are fitted to complete a plurality of rows of supports as shown in FIG. At this time, the protrusions 11 of the support 1

Is fitted into the storage case 3 shown in FIG. 2 while being inserted from the top opening. At this time, the inclined surface 111 a of the locking projection 111 of the projection 11 of the support 1 is guided by the guiding inclined surface 31 a of the storage case 3 and locked in the locking hole 33.

As described above, when the supports 1 are joined to other adjacent supports, the concave portions 10 and the convex portions 11 on the mutually opposing surfaces are fitted as shown in FIG. The stop hole 101 and the locking projection 111 of the projection are also engaged. Therefore, it is possible to prevent the support members 1 from being separated from each other due to upward displacement, and to receive a force that shifts in the longitudinal direction due to an external force.
The rising surface and the falling surface on both sides of the concave portion 10 and the convex portion 11 of each support body 1 fitted together further form the inner side surface 101b of the locking concave portion 101 and the side surface 111 of the locking projection 111.
By joining with b, this longitudinal displacement is prevented.
In the support 1, the entire surface of the concave portion 10 and the convex portion 11 is joined to the entire surface of the concave portion 10 and the convex portion 11 on the side surface of the adjacent support, and furthermore, the locking projecting from the convex portion. Protrusion 1
11 is a locking hole 101 of the concave portion 10 to which the outer peripheral surface is fitted.
, One side of the joining surface of the supports 1... Does not open unexpectedly, so that the terminal pins 2 of one support 1 are connected to the terminal pins of the other support. Can be prevented from coming into contact with. Further, the plurality of supports 1 in the joined state
Are stored in the storage case 3, the locking projections 111 of the projections 11 are guided by the inclined surface 31a of the storage case and engage with the locking holes 33 of the case. Therefore, not only can the supports 1... Be prevented from falling out of the storage case 3, but also the longitudinal displacement between the plurality of supports 1 and the storage case 3 can be prevented.

[0017]

According to the present invention, since a row of terminal pins is implanted in each support, the support can be formed by injection molding as in the prior art, and the terminal pins are press-fitted. Even if the support is not damaged, by joining a plurality of the supports, it is possible to realize multi-rows of terminal pins, and to cope with high-performance electronic equipment, and to reduce the space efficiency inside the electronic equipment. Can be enhanced. In addition, since the supports are joined to each other via the concave portion, the convex portion, the locking protrusion, and the locking hole, the joined state can be firmly maintained, and the lateral displacement between the joined supports is completely reduced. Is prevented. The plurality of supports can be stored in the storage case so as not to be easily detached. Further, since all the supports can be injection-molded into the same shape, the same mold can be used, and the manufacturing cost can be reduced.
