Problems solved by technology

[0006] The first object of the present invention is to provide a riveted ignition switch and its manufacturing method in order to solve the difficult operation during riveting in the manufacturing process of the riveted ignition switch, and also prone to misplacement and missing placement. Simplify the operation procedures during riveting, and effectively avoid the problems of misplacement and omission, so as to reduce labor costs and improve the pass rate of products
[0007] The second purpose of the present invention is to solve the problems of the manufacturing process of the riveted ignition switch that it is difficult for the operator to place the reflow strips during injection molding, and the multiple reflow strips are easy to be placed in the wrong position or direction, or even missed. A riveted ignition switch and its manufacturing method, which not only facilitates the placement of the return bar during injection molding, but also effectively avoids misplacement and missed placement of the return bar, thereby helping to reduce labor costs and improve the pass rate of products

Embodiment 1

[0034] Embodiment 1: as figure 1 As shown, a riveted ignition switch includes an injection-molded support 1, five copper return strips 2 embedded in the support as inserts, and three elastic strips riveted on the upper side of the return strip by rivets 4. The contact piece 3 is provided with a raised contact 31 on the elastic contact piece, and each return bar includes a connection terminal 21, the head of the rivet is located on the lower side of the return bar, and the upper end of the riveting column of the rivet is riveted on the elastic contact piece. on the upper surface.

[0035] In order to facilitate riveting, the elastic contact piece includes a roughly rectangular riveting portion 32 , and a riveting hole is provided on the riveting portion, and the riveting column of the rivet passes through the riveting hole of the riveting portion. Preferably, we can set two riveting through holes on each riveting part; or, connect the riveting parts of two adjacent elastic con...

Embodiment 2

[0041] Embodiment 2: a kind of manufacturing method of riveting type ignition switch as described in embodiment 1, comprises the steps:

[0042] a. Install the support molding mold used to form the ignition switch support on the injection molding machine, put the reflow strip as an insert into the injection mold in the split mold state, each reflow strip includes a terminal, and reflow Corresponding riveting holes are set at the place where the strip needs to be riveted with the elastic contact piece;

[0043] b. Clamp the injection mold and start injection molding, so as to obtain a semi-finished product including a support and a return bar, the return bar is embedded in the support, and a first punching through hole is formed on the support of the semi-finished product;

[0044] c. Put the connecting gasket connected as a whole through the lower connecting strip into the lower mold of the riveting die for positioning, and the riveting hole of the connecting gasket is interfe...

Abstract

The invention discloses a riveting-type ignition switch and a manufacturing method. The ignition switch comprises a support seat, a backflow bar which is embedded into the support seat and is providedwith a wiring terminal, and an elastic contact piece which is riveted to the upper side of the backflow bar. The elastic contact piece comprises a riveting part which is riveted to the backflow bar,and a rivet is sleeved by connecting gaskets which are attached to the lower side of the backflow bar. Lower connecting bars are respectively disposed between the connecting gaskets, and the positions, corresponding to the lower connecting bars, of the supporting seat are provided with two first punching through holes. Upper connecting bars are disposed between the adjacent riveting parts in an integrated manner, and the positions, corresponding to the upper connecting bars, of the supporting seat are provided with two second punching through holes. During riveting, the integrated elastic contact piece and the integrated connecting gaskets and the rivet are placed in a riveting die. After riveting, the adjacent parts of the lower connecting bars and the connecting gaskets are punched through the punching technology, and the adjacent parts of the upper connecting bars and the riveting parts are punched, thereby obtaining an applicable product. According to the invention, the productionefficiency is improved, the manual cost is reduced, and the improvement of the processing quality is facilitated.

Description

technical field [0001] The invention relates to the technical field of engine ignition switch manufacturing, in particular to a riveted ignition switch and a manufacturing method that are beneficial to realize automatic production. Background technique [0002] The engine ignition switch is an essential component of the car. There are many structural forms of the existing engine ignition switch. One of the common engine ignition switches includes a plastic support, and several return bars and For the elastic contact piece of the movable contact, the return bar is embedded in the support, one end of the return bar is provided with a terminal, and the other end of the return bar is connected with the elastic contact piece. [0003] This kind of engine ignition switch is usually manufactured by the following process: firstly, the plastic support is formed by injection molding process. During injection molding, the copper return strip is integrally formed on the support as an in...
