Abstract

The utility model relates to a main circuit switch, which comprises a pair of mutually symmetrical contact heads (6) and conductive plates (1) connected to the rear part of the contact heads (6). The utility model is characterized in that the contact heads (6) is formed after multiple pairs are stacked. Each pair of contact heads (6) are sheathed on connecting posts (2) which are perpendicular to the planes of the contact heads; both ends of an annular clamping spring are respectively connected to each pair of contact heads (6); the connecting post (2) is mutually fixedly connected with a conductive plate (1). Because two original conductive plates are turned into one conductive plate, the resistance is diminished; the electric loss is also diminished; the heat generation of the conductive plate can be reduced.

Description

The main circuit connector

The utility model relates to a kind of circuit connector.

In the prior art, circuit connector is made up of the contact of a pair of lip and the pair of conductive plate that is connected with described a pair of contact.Because the pair of conductive board plane is superimposed together, the conductive plate heating not only wastes energy but also be prone to accident when therefore having electricity to circulate in contact.

The main circuit connector that provides a kind of caloric value little is provided the purpose of this utility model.

The technical solution of the utility model is: a kind of main circuit connector, comprise symmetrical a pair of contact and be connected in the conductive plate at described contact [6] rear portion, described contact is made up of after stacking many, described every pair of contact is enclosed within on the joint pin perpendicular to the contact plane, be connected with the two ends of annular spring on described every pair of contact respectively, described joint pin and a conductive plate are fixedly connected.

The utility model compared with prior art has following advantage:

Because original two conductive plates are become a slice conductive plate, so resistance decreasing, electrical loss also diminishes, and can reduce the heating of conductive plate.Be connected with the two ends of jump ring on the every pair of contact, make contact have better elastic, insert repeatedly at plug that the back contact mechanical deformation can not occur between the contact, can prolong its useful life.

The utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing 1 is a structure front view of the present utility model;

Accompanying drawing 2 is the left view of accompanying drawing 1; Wherein:

[1]. conductive plate; [2]. joint pin; [3]. jump ring; [4]. rivet; [5]. the spline plug-in unit; [6]. contact; [7] binding post hole;

Embodiment: referring to accompanying drawing 1 and accompanying drawing 2, a kind of main circuit connector, comprise symmetrical a pair of contact [6] and be connected in the conductive plate [1] at described contact [6] rear portion, described contact [6] is made up of after stacking many, generally stacks to good with three pairs, four pairs contacts.Described every pair of contact [6] is enclosed within on the joint pin [2] perpendicular to the contact plane, is connected with the two ends of annular spring [3] on described every pair of contact [6] respectively, and the two ends of described jump ring [3] are connected jump ring [3] by rivet [4] with joint pin [2].Described joint pin [2] is fixedly connected with a conductive plate [1].The preceding facial planes of described conductive plate [1] is perpendicular to the axial line of joint pin [2], rear portion plane torsion 90 degree of described conductive plate [1], make this rear portion plane parallel in the axial line of joint pin [2], when rear portion conductive plate [1] was connected with lead by being inserted in binding post on the binding post hole [7] like this, the safe distance between other adjacent conductive plate can be guaranteed.The rear portion of described conductive plate [1] has binding post hole [7].Be inserted with spline plug-in unit [5] in the breach on the described joint pin [2], described spline plug-in unit [5] also is inserted in the breach of described contact [6], and described spline plug-in unit [5] can stop contact [6] to rotate.
