Abstract

The utility model relates to an improved type power-supply plug, comprising a terminal seat, a terminal, and conducting wires, and is characterized in the fastening structure of the terminal and the terminal seat, wherein, the catch hook of the inner side of the terminal seat is sprung to be clamped into the punch hole of the back end of the terminal; the barrier sheet on the back end of the terminal is abutted on the back-wall face of the terminal seat to make the terminal seat and the terminal wedged fastening and preliminarily fixed. In processing, a routine of fixing with plastic cement can be omitted. The terminal forms a hollow cylinder shape, and is formed by the stamping and folding of a metal plate. The utility model has the advantages of material saving and high work efficiency.

Description

Attaching plug

The utility model relates to the attaching plug of electrical appliance, mainly is the internal structure of improving plug.

The attaching plug of electrical equipment, though the description difference, it constitutes all terminal and terminal base.The terminal base appropriate location is equipped with terminal hole.Conventional plug inner box processing mode, be with terminal tentatively be inserted in ejection formation die needed in, after waiting to squeeze the dried solid moulding of the plastic rubber material of injecting in the mould, terminal promptly is coated on the terminal hole of terminal base, again with plastic rubber material ejection formation program, plastic rubber material squeezed penetrates in the box body die holder, plastic rubber material do after solid the plug box body.The plug of this structure because terminal is to be inserted in terminal hole, when plastic cement penetrates operation, is made comparatively difficulty, and terminal position also easily goes out error.

The purpose of this utility model is to improve the defective of above-mentioned plug, provides a kind of terminal to combine attaching plug firm, easy to process with terminal base, to improve the quality of products and working (machining) efficiency.

The technical solution of the utility model is: terminal is located in the terminal base, and lead links to each other with terminal.Establish terminal hole on the terminal base, the terminal hole medial margin is provided with to pull and colludes; A perforation is established in the terminal rear end, perforation reverse side lateral margin has catch, after terminal inserts terminal hole, pulling, colluding upsprings snaps in the perforation of terminal tails, catch on the terminal props up the terminal base rear wall, and terminal penetrates program with plastic cement again after preliminary like this fixing, make plastic rubber material clad terminal seat rear surface, form the plug box body of a firm combination.

Terminal is a hollow cylindrical, and collapsing with the metallic plate punching press forms, and terminal has a longitudinal seam.

The more conventional plug of the utility model has following superiority: 1. combines, do not need with the plastic cement extrusion molding terminal to be coated in the terminal hole of terminal base earlier because of terminal and terminal base are that chimeric clip is preliminary, thus easy to process, and terminal combines with terminal base firmly; 2. terminal is a hollow cylinder, and the available metal plate strikes out the continuous terminal plate fast, collapse terminal.Than the solid cylinder terminal, can save the man-hour of terminal distribution, save material, improve working (machining) efficiency.

Below in conjunction with description of drawings structure of the present utility model and embodiment.

Fig. 8 implements 2 finished product appearing diagram.

Please see Figure shown in 2, attaching plug includes terminal base 21, terminal 22, and terminal base is equipped with 2 terminal holes 211, and the terminal hole medial margin is respectively established one and pulled and collude 213,2 preformed holes 212 are arranged between the two-terminal hole, and the terminal base rear wall is provided with 2 interlayers 210 shown in two vertical poles 214 or Fig. 6 b.Terminal 22 ends are established a perforation 228, and perforation reverse side lower edge has washed off catch 227.Terminal is a hollow cylindrical, processes as shown in Figure 4, and collapsing by the quick punching press of shape with metallic plate forms.

Figure 3 shows that the fixing of terminal, earlier terminal is inserted terminal hole 211 respectively, 213 tool elasticity are colluded in pulling of terminal hole inboard, the perforation 228 of terminal ends is through pulling when colluding, pulling to collude just to snap in to form in the perforation 228 fixes, and terminal ends catch 227 props up the terminal base rear surface simultaneously, and terminal and terminal base are tentatively fixing, be combined into one (as shown in Figure 5), then lead 31 placed in the angle of two vertical poles 214 (or between two interlayers 210 shown in Fig. 5 a).

Behind the preliminary connecting shaping of above-mentioned member, again terminal base 21 is fixed in the box body die holder, squeeze and inject plastic rubber material.Preformed hole 212 on the terminal base 21 helps plastic rubber material and does expanding with heat and contract with cold in the solid process.Finished product as shown in Figure 6.

Above-mentioned box body is looked the plug specification in country variant or area and is selected difform mould for use.

Embodiment 2, as Fig. 7, shown in Figure 8, and this kind plug end stroma 21 no vertical pole 214 or interlayers 210, structure is simpler, and terminal structure is the same.

The feature of this utility model also can be used for making 3 n pin package ns.The equalization that the Fan Yiben creation characteristic is done changes or the equivalence design, all belongs to the protection range of this patent.

Claims

1, a kind of attaching plug comprises terminal base [21], terminal [22], lead [31], and terminal is positioned at the terminal hole [211] of terminal base, and lead links to each other with terminal, of the present utility model being characterised in that: terminal hole [211] medial margin is provided with to pull and colludes [213]; There is a perforation [228] terminal [22] rear end, and perforation reverse side lateral margin has catch [227]; After terminal inserts terminal hole [211], pull and collude [213] and snap in the perforation [228] of terminal, catch [227] props up the terminal base rear surface.
