Abstract

The utility model discloses a thread wiring terminal hardware which includes a compression fixing plate, a bolt and a compression plate. The compression fixing plate is provided with a sawtooth-shaped tooth; the thread wiring terminal hardware is fixed by the sawtooth-shaped tooth of the compression fixing plate by being embedded into a plastic insulating substrate. The bolt and the compression fixing plate are connected together by the technique of riveting and pressing the compression fixing plate; therefore, the bolt can only freely rotate relatively to the compression fixing plate and around the central shaft of the compression fixing plate, but can not move relatively to the compression fixing plate and along the direction of the central shaft of the compression fixing plate, thereby achieving the goal that the head of the bolt can rotate freely, vertically and downwards without falling off.

Description

Screw-type binding post hardware

Technical field

The utility model relates to a kind of binding post hardware, relates in particular to a kind of screw-type binding post hardware.

Background technology

Generally speaking, the screw-type binding post all is to utilize moving up and down of bolt to drive tension disc crimping lead.The drawback of this kind structure is: require the head vertical-horizontal of bolt to face down when product is equipped with, therefore, when bolt unclamps lead, often, bolt thread cause bolt to drop because withdrawing from tension disc fully, when particularly the user used electric screwdriver to finish the locking wire operation, the defective that bolt drops was just more obvious.

Summary of the invention

The purpose of this utility model is the problem that exists at existing screw-type binding post hardware, provides a kind of bolt head that the drop screw-type binding post hardware of phenomenon of bolt can vertical any horizontal plane take place around its central shaft rotation.

For achieving the above object, the utility model adopts following technical scheme:

A kind of screw-type binding post hardware comprises:

The line ball fixed head has a base plate, has a unthreaded hole on the base plate; Extended upward two side plates from the base plate both sides, had the latch that is used for the line ball fixed head is bumped into insulating body on the side plate, the surface of described line ball fixed head has the plating top layer;

Tension disc has screwed hole on it, its surface has the plating top layer; And,

Screw comprises head and thread rod part, and wherein, described thread rod part matches with tension disc after passing the unthreaded hole of described line ball fixed head, and has the radially flange of expansion at the terminal part of thread rod part;

Preferably, the terminal process riveted joint of described shank of screw portion has the radially flange of expansion.

Preferably, described line ball fixed head prolongs a side of its base plate, extends a U type groove by a changeover portion to the direction that is parallel to base plate and is lower than base plate.

Preferably, the latch on two side plates of described line ball fixed head is a zigzag.

Preferably, described tension disc, its screwed hole is positioned at the geometric center of tension disc, at the upper surface of tension disc, have a convex around the screwed hole, and screw thread extends to whole convex always.

Preferably, described tension disc is in the outstanding semiellipse type projection of oriented its lower surface of its edge.

Preferably, described tension disc is square, and semiellipse type projection lays respectively at the edge on four limits of tension disc.

Preferably, described bolt has the plating top layer.

Usefulness of the present utility model: on the one hand, in the time of can preventing effectively that bolt from withdrawing from the tension disc screw thread, the phenomenon that bolt drops takes place from the line ball fixed head; On the other hand, has stronger anticorrosive property.

Fig. 2 is a full sectional view of the present utility model;

Fig. 3 is the utility model working state schematic representation.

Embodiment

The utility model comprises line ball fixed head 1, tension disc 2 and bolt 3 as shown in Figure 1; Wherein,

Line ball fixed head 1, its surface are coated with electroplates the top layer, guarantees good electric conductivity and antiseptic property, and described line ball fixed head comprises:

Can be square base plate 11, have a unthreaded hole on the base plate, be connected with bolt;

The base plate both sides extend upward two side plates 12, have latch on the side plate 12, and latch can be zigzag, by latch line ball fixed head 1 are bumped in the insulating body, fixing whole screw-type binding post hardware; And,

Line ball fixed head 1 have a side from base plate by a changeover portion to being parallel to base plate, and the U type groove 13 that the direction that is lower than base plate is extended, utilize the bottom land plane in this U type groove outside, can contact effectively, guarantee electrical equipment energising conducting with the shell fragment of electric component.

Tension disc 2 can be square plate, can punching press on it forms the convex 21 of a circle, is drilled with the screwed hole that cooperates with bolt 3 at the center of convex, and (as depicted in figs. 1 and 2), convex 21 can increase effective contact length of bolt 3 and tension disc 2; Can distinguish punching press to the outstanding semiellipse type projection 22 of its lower surface in the edge on four limits of tension disc 2, use semiellipse type projection 22 to compress lead, can effectively prevent its wire dropping, the surface of tension disc is coated with electroplates the top layer, reaches anticorrosion purpose.

As shown in Figure 2, bolt 3, pass the unthreaded hole of line ball fixed head 1, cooperate with the screwed hole of tension disc, threaded rod end 5 (as shown in Figure 2) by riveting bolt 3, guarantee that line ball fixed head and bolt are in axial location, in addition, because line ball fixed head 1 has been bumped in the insulating body by its zigzag latch, thereby make bolt 3 with respect to line ball fixed head 1 when 4 rotations of its central shaft, can not move along its central shaft 4 directions with respect to line ball fixed head 1, promptly bolt can not come off from the line ball fixed head.The thread segment of bolt 3 is coated with electroplates the top layer, reaches anticorrosion purpose.

Screw-type binding post hardware described in the utility model is when work, by bolt 3 rotations tension disc 2 is moved to base plate 11 directions of line ball fixed head 1 along the central shaft 4 of bolt 3, by its half elliptic projection lead 6 is clamped (as shown in Figure 3), and finish current delivery by electroplating the top layer.
