Abstract

The utility model provides a four-contact-point spring-type contact connecting component, being composed of a group of spring pieces and a group of contact pieces; each contact piece is an L shape and is arranged in a guide-track groove corresponding to a wire connecting terminal; the wire connecting terminal is fixed with a bottom shell; each spring piece is an incurve shape and is fixed in a hole corresponding to a wire connecting terminal box; the spring pieces are spliced with the contact pieces, and bulges at the top ends of the spring pieces are connected with a circuit board, and the wire connecting terminal box is fixed with the circuit board and an upper cover at the same time, and the circuit board is not fixed independently by a bolt. The spring pieces are movably matched with the contact pieces in a splicing way. Compared with the prior art, four contact points on each spring piece are conducted with the contact pieces, therefore, the connecting component has better communicating and electric-conducting performance compared with the traditional component with two contact points; the site installation is carried out without any tools, plugging is direct, the splicing is reliable and the installation is convenient, thus being maintained and preserved.

Description

Spring contact coupling assembling

Technical field

The utility model belongs to electric contact coupling assembling technical field, especially for the contact coupling assembling of electric equipment products such as the manual fire alarm call point in the fire protection alarm system, module, fire hydrant button.

Background technology

At present at fire protection alarm system product such as manual fire alarm call point, module, its electrical lead wire connects the spring connector assembly that adopts 2 contact contacts usually in the fire hydrant button, as ZL03273129.9, it is to be fixed on the cushion socket that constitutes in the corresponding groove seat with U type spring leaf to be plugged on the spring plug-in unit, because two contact (i.e. 2 contact contacts) respectively about U type spring leaf with the spring plug-in unit, in this mode as 2 contacts all do not contact, then with wiring board on just be electrically connected and can't realize, cause the above-mentioned fire protection alarm system product can not Normal Alarm.

Summary of the invention

The utility model provides patching of a kind of 4 contacts safe and reliable spring contact coupling assembling.Realize that the technical scheme that above-mentioned purpose adopts is: a kind of spring contact coupling assembling comprises one a group of spring leaf and a winding contact.Each contact chip is the L type, and in the binding post corresponding guide rail of packing into the groove, binding post and drain pan are fixed; The top of each spring leaf curves four submissile reeds toward in, there is the projection (hereinafter to be referred as interior curved spring leaf) that is connected with wiring board at the center of spring leaf, is fixed in the corresponding hole of binding post box.Contact chip and spring leaf are pegged graft, and the projection at the top of spring leaf is connected with wiring board, and the binding post box is fixed with wiring board, loam cake simultaneously, and wiring board is no longer fixing separately with screw.

In the described spring leaf connector assembly, the quantity of spring leaf and contact chip is decided according to the actual requirements, and spring leaf is the plug-in type activity with contact chip and cooperates.

The utility model is compared with prior art: every group of spring leaf has four contacts and contact chip conducting, has good connection electric conductivity; On-the-spot installation is not by any instrument, and directly plug is pegged graft reliably, and is easy for installation, is convenient to safeguard, maintain.

Description of drawings:

Below in conjunction with Figure of description the utility model is further described.

Fig. 1 is a profile of the present utility model.

Fig. 2 is that Fig. 1 is along A-A cutaway view.

Fig. 3 be interior curved spring leaf schematic diagram, wherein Fig. 3 a is a front view, Fig. 3 b is a vertical view, Fig. 3 c is a left view.

Fig. 4 is the schematic diagram of L type contact chip, and wherein Fig. 4 a is a front view, and Fig. 4 b is a vertical view, and Fig. 4 c is a left view.

The content that Reference numeral is represented among the figure is respectively:

1, loam cake; 2, drain pan; 3, binding post box; 4, interior curved spring leaf; 5, binding post; 61, guide-track groove; 6, L type contact chip; 7, wiring board; 8, the projection at spring leaf top; 9, the triangle of the back taper type at spring leaf top

Embodiment:

The utility model generalized section as shown in Figure 1 there is shown to be and bends spring leaf 4 and a L type contact chip 6 in one that patches shape.Each spring leaf 4 is interior bendings, packs in the binding post box 3 corresponding square holes with the riveted joint form, and binding post box 3 and wiring board 7, loam cake 1 are fixing; Each L type contact chip 6 is packed in the binding post 5 corresponding guide rail grooves 61, and fixing with drain pan 2; L type contact chip 6 is pegged graft with spring leaf 4.Fig. 1 bottom is the state of do not pack into spring leaf 4 and contact chip 6, shows the correlation of binding post 5 and guide-track groove 61.

Fig. 3 is the view of the interior curved spring leaf 4 in the binding post box of not packing into, a H type opening is arranged at the top of interior curved spring leaf 4, the H type has the rectangular preiection 8 of one group of contour symmetry and the triangle 9 of 8 back taper types in two ends up and down simultaneously, and the projection 8 at the top of interior curved spring leaf 4 is connected with wiring board 7; The triangle 9 of back taper type is used for spring leaf 4 and is fixed on binding post box 3 better, and the bottom of spring leaf 4 will utilize self elasticity of spring leaf that L type contact chip 6 is stepped up.Fig. 2 as seen, about in the present embodiment there being the square hole of terminal board 3, symmetry up and down, corresponding in curved spring leaf 4 also be about, the front and back symmetry, L type contact chip vertically is connected with spring leaf 4, laterally can be connected with external power line, be a kind of good connected mode.Since spring leaf 4 be about, the front and back symmetry, correspondingly, contact chip 7 also be about, the front and back symmetry, shown in Fig. 4 c, L type contact chip 6 is the contact chip of shape such as alphabetical L, pegs graft respectively for two that L type contact chip extends upwardly among Fig. 4 a and enters per 2 spring leafs (shown in Fig. 3 c) of spring leaf 4, and then spring leaf has 4 contacts and contact chip conducting, as long as there is a contact to connect, just can realize electric grafting function.

This spring connector assembly is made up of one a group of spring leaf 4 and a corresponding winding contact 6, is mutually to patch to cooperate and 4 contact contacts, as long as a contact can contact, just can make above-mentioned fire protection alarm system product Normal Alarm.The quantity of spring leaf 4 and contact chip 6 can be provided with flexibly according to wiring board 7 function needs.
