Abstract

The utility model relates to a binding post of an electrical equipment, in particular to a loose core rivet type binding post used on a storage battery, which comprises a binding post and a loose core shaft, and adopts the design structure that: the binding post is an L-shaped terminal board be bending edges, the end part of a bent plate at one side thereof is semicircular, and a bent plate at the other side thereof is rectangular, and a columniform rivet body that is formed by stamping and stretching, connected with the bent plates into a whole and provided with a center hole is arranged on a semicircular side plate; and the loose core shaft consists of a shaft body much longer than the terminal board and a head part of which the diameter d is larger than that of the shaft body, and a dividing body of the head part and the shaft body is formed by a breaking body of which the diameter is smaller than that of the shaft body. The utility model has the advantages that: 1. the binding post is easy in installation and use and excellent in conductivity when in use, and the tensile property is greatly improved, and 2. the height sameness can be ensured when using a plurality of binding posts.

Description

Self-plugging rivet type binding post

Technical field

The utility model relates to a kind of binding post of electric equipment, is a kind of self-plugging rivet type binding post that is used on the storage battery specifically.

Background technology

The binding post that uses on the existing battery cell case is made up of conventional rivets, lug plate usually.Owing to adopt to divide body structure, there is poor electric conductivity, easily loose or dislocation, sealing property is bad and cause battery to reduce greatly useful life, even to no effect, also needs follow-up welding simultaneously, causes problems such as its use cost height, efficient are low, weak effect.

Summary of the invention

The purpose of this utility model is improved the problems referred to above exactly, and a kind of self-plugging rivet type binding post is provided, and the electric conductivity of storage battery is improved, and use cost is low, efficient is high, effective.

For achieving the above object, technical solution of the present utility model is finished as follows: a kind of self-plugging rivet type binding post is made up of binding post, the axle of loosing core, its project organization is: binding post is the terminal block that a flanging becomes " L " shape, the end of one side flap is that semi-circular shape, opposite side flap are rectangular-shaped, and a cylindrical rivet body that is linked to be an integral body, band centre bore through punching stretch formation and flap is arranged on semi-circular shape Side plate; The axle of loosing core is by constituting than the much longer axis body of terminal block with greater than the head of axis body diameter d, and the boundary portion of head and axis body is by constituting than the little fracture portion of its axis body diameter.

The center-hole diameter D of the axis body diameter d=rivet body of the above-mentioned axle of loosing core, they are stationary fits.

The material of above-mentioned binding post, the axle of loosing core is a metallic object.

The beneficial effects of the utility model are: have easy dress, handy when 1, using, the more important thing is that the sealing and the electric conductivity that can guarantee battery are good, 2, in the time of with a plurality of binding post, can guarantee height homogeneity, 3, use the pull resistance of back product also can be greatly enhanced.

Embodiment

As shown in Figure 1, 2, 3, the utility model is made up of binding post 1, the axle 2 of loosing core, binding post 1 is the terminal block 11 that a flanging becomes " L " shape, the end of one side flap 111 is that semi-circular shape, opposite side flap 112 are rectangular-shaped, and a cylindrical rivet body 12 that is linked to be an integral body, band centre bore 121 through punching stretch formation and flap 111 is arranged on semi-circular shape Side plate 111; The axle 2 of loosing core is by constituting than the much longer axis body 21 of terminal block 11 with greater than the head 22 of axis body 21 diameter d, and the boundary portion of head 22 and axis body 21 is by constituting than the little fracture portion 23 of its axis body 21 diameters.The loose core center-hole diameter D of axle axis body 21 diameter d=rivet body 12 of 2, they are stationary fits.

The material of above-mentioned binding post 1, the axle 2 of loosing core is a metallic object.

During use, self-plugging rivet type binding post is put into the wiring hole of battery 3, extract out from rivet body hole 121 with the hand riveter axle 2 of will loosing core, the distortion of rivet body 12 ends is fixed on rivet body 12 on the wiring hole of battery 3, sees Fig. 4.
