Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for manufacturing a jack for a modular connector used for connecting a telephone.

[Background Art 1] As shown in FIG. 8, this type of modular connector jack is connected by diagonally protruding one end of a plurality of wires 2 on the inner wall surface of a cylindrical hashing 9 made of synthetic resin. , α portion 5 is formed, and each contact and ζ portion 5 are introduced into a plurality of grooves formed from the front surface to the side surface of the plug to be inserted in the direction of the arrow, and are penetrated into the grooves. The wire is constructed so as to come into contact with the contact piece, and the method for manufacturing this gloss is to insert the square wire 2 into each insertion hole 12 from the direction of the arrow in the figure, and then bend the contact portion 5 diagonally. , or to prevent the foil from coming out, bend the contact portion 5 and the connecting terminal MS3 as shown in Figure 9, or insert the terminal at an angle as shown in Figure 10 to reduce the number of bends. 5 or the insertion hole 12 and the wire 2
Various attempts have been made to prevent looseness between the housings, such as dividing the housing 9 into two as shown in FIG.
In any of the methods shown in FIGS. 8 to 10, it is not easy to insert the wire 2, and there is play between the wire 2 and the insertion hole 12. In the method shown in FIG. 2
There was a problem in that it was not easy to hold.

In addition, as a countermeasure, a method of integrally molding the wire 2 and the housing 9 can be considered, but the number of wires 2 is 2.
Because there are various specifications such as book, 4 pieces, and 6 pieces,
There is a problem in that it is necessary to prepare a mold for each, which increases the equipment cost.Also, the number of contacts is all U-made with the maximum number required, and unnecessary contact parts 5 are cut off according to the specifications. The problem with this method is that the product cost is rather high when the number of contacts is small.

[Object of the Invention] The present invention has been made in view of the above-mentioned problems, and its purpose is to enable the integral molding mold to be used in common for various specifications having different numbers of contacts, and to achieve this. To provide a method for manufacturing a shutter of a modular connector with a simple process and low equipment cost.

[Disclosure of the Invention] Accordingly, the method of the present invention is to connect a metal hoop with one end connected to the substrate 1 via the connection terminal portion 3, and each end connected to the substrate 1 via the connecting portion 4 that communicates with each other. A step of punching out a plurality of wires 2 from a substrate 1 made of material, a step of cutting between the connecting portion 4 and the substrate 1 and bending the wires 2 upward at a predetermined point, and connecting terminal portions 3 of the wires 2 and contacts A process of integrally molding the synthetic resin housing 9 on a part other than the part 5, a process of cutting off the connecting part 4 from the wire 2 and bending the contact part 5 diagonally downward, and a process of cutting the connecting terminal part 3 from the board 1. Therefore, in the punching process, the unnecessary wire 2 is cut out, leaving the base end 3a of the connecting terminal part 3, according to the specifications.

[Function] According to the above configuration, even if the specifications of the contact and α numbers are different, the base end portions 3a of the connecting terminal portion 3 are always provided in the required maximum number during integral molding, so that the upper and lower molds are This prevents the formation of cracks in the gap formed between the joints of A and B, and the wire insertion hole on the side of the joint 5 is made of an upper mold to avoid the wire 2 being bent upward. Since the slide core C is divided into two parts, only the slide core C needs to be connected, and a plurality of them need only be prepared according to the specifications of the number of contacts, and in the end, it is possible to correspond to various specifications of five points of contact at extremely low cost.

[Example 1] Fig. 1 and Fig. tItJ2 show a plan view and a side view of each step of the method of the present invention, and Fig. 1 (a) shows a metal 7
- The process of punching out a plurality of wires 2 from a substrate 1 made of plastic material with both ends of each wire connected to the substrate 1, with one end of each wire 2 connected to the substrate 1 via a connecting terminal portion 3. However, the other end is connected to the substrate 1 via a connecting portion 4 that connects the wires 2 to each other. Actually, in this state, gold plating is applied to the contact portion 5, that is, the portion surrounded by the broken line in FIG. Note that 6 is the capacitor connection hole, 7゜8
is a positioning hole. Next, in figure (b), the connecting part 4
and the substrate 1 are cut, and the wire 2 is bent upward at a predetermined location. At this time, since the tip of the wire 2 is integrated with the connecting portion 4, the bending operation is extremely easy. Next, as shown in FIG. 1E, a housing 9 is integrally molded from synthetic resin on a portion of the wire 2 other than the connecting terminal portion 3 and the contact portion 5.

At this time, if only the upper and lower molds A and B are used, the wire 2 protruding upward will get in the way of the upper mold A, so a slide core C is used on one side of the wire 2. In Figure 2(d), after the connecting part 4 is cut off from the tip of the wire 2, the contact part 5 protruding from the stepped part of the housing 9 is bent diagonally downward, and further in Figure (e), The connection terminal part 3 is the board 1
The jack shown in FIGS. 3 to 5 is completed. In FIG. 5, 10 is a stopper with which the tip of the plug comes into contact, 11 is an engagement step of the plug attachment/detachment lever, and C is the slide core portion.

Now, Figure @1 to Figure ft55 explain the case where the number of contacts is 6, but depending on the user's specifications,
The required number of contacts may be four or two. In that case, of course, it is necessary to reduce the cost of materials and plating, so the number of wires 2 must be reduced. Figures 6 and 7 show cases where the number of contacts is 4 and 2, respectively. This figure shows the punching process of , and corresponds to Figure 1(a). In each figure, unnecessary wires are cut off leaving only the base end 3a of the connecting terminal portion, according to specifications. This is to save the material tube and to prevent the unnecessary connection terminal part 3 from getting in the way of the wiring.The reason why the base end part 3a is left is to make the upper and lower molds A and B common for each specification. This is because if this part is also removed because it is used, a gap will be created in the gap that will be left behind. Also, regarding the wire insertion hole that is no longer needed on the 1'7 section 5 side, as shown in Fig. fjS2 (c), only the slide core C used to avoid the wire 2 bent upward is inserted. It can be replaced according to the change in the number of contacts.

[Effects of the Invention] As described above, in the 91'tL method of the Moziera type connector according to the present invention, unnecessary wires are removed from the base end of the connecting terminal portion in the step of punching out the wires from the metal 7-ply material. Since this part is removed by leaving a part of the mold, it is possible to prevent the formation of cracks in the gap formed between the upper and lower molds at this part when integrally molding the housing with synthetic resin. This has the effect of using a common mold for each specification, making it possible to adopt an integrated molding method with a simple process, high processing accuracy, and no wobbling of the contact at a low cost. It has advantages.
