Abstract

The utility model discloses a probe for the connector of a main circuit in a switch device. The probe has a conductive row and movable probe pieces installed relatively. Both ends of a C-shaped spring is in compression joint on the movable probe pieces installed relatively; a filler block is clamped by one pair of or a plurality of pairs of movable probe pieces. The tail of the movable probe pieces is in compression joint on two sides of the conductive row. The utility model has small heat generation and low temperature rise. Each pair of movable probe pieces can synchronously offset, and can not generate dieback phenomenon when spliced with static probes. Electrical faults are uneasy to generate.

Description

The contact that the main circuit connector is used

The utility model relates to the connector in a kind of power switchgear.

Moving contact in the switchgear often and fixed contact inserts, pull action, and this just requires moving contact can satisfy the foozle of fixed contact, can be good fit with fixed contact.The moving contact of at present domestic laminated structure commonly used, the moving contact sheet of its symmetric arrangement adopts " C " shape spring to keep resilient clamp power, is used for clamping static contact.In the rear end of moving contact sheet is to adopt by pin and busbar ways of connecting, or adopts the connected mode of activity obvolvent that turns on the busbar.Make the activity within the specific limits of moving contact sheet, just must or turn and leave the gap between the axle at moving contact sheet and pin, cause contact resistance big, caloric value be big, and temperature rise easily causes electric fault.Many during when adopting simultaneously to the moving contact sheet, nonsynchronous skew easily takes place, cause when patching the dieback phenomenon might take place with fixed contact.

The purpose of this utility model is to provide a kind of heating little, and adopts and manyly can guarantee simultaneous bias during to the moving contact sheet, and the contact that the main circuit connector of dieback phenomenon is used can not take place.

In order to achieve the above object, the technical solution of the utility model is: the contact that a kind of main circuit connector is used, have busbar and moving contact sheet to adorning, the two ends of one " C " shape spring are crimped on the moving contact sheet of adorning, one pad is clamped by one or more pairs of moving contact sheets, and the afterbody of moving contact sheet of dress is crimped on two sides of busbar.

After adopting said structure, owing to set up pad, pad is clamped by one or more pairs of moving contact sheets, pad plays the balance pivot effect, not only can control openings of sizes to the moving contact sheet front end of dress, and can guarantee each to moving contact sheet energy simultaneous bias, patching Shi Buhui generation dieback phenomenon with fixed contact.Simultaneously, because moving contact sheet afterbody is crimped on two sides of busbar, like this when fixed contact inserts moving contact sheet front end, can strut and have the prestressed moving contact sheet of certain spring front end, then because the effect that fulcrum reach and spring pressure increase compresses busbar more, and the contact zone does not have the gap, heating is little during use for the afterbody of moving contact sheet, temperature rise is low, is difficult for causing electric fault.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Figure 14 is that the utility model installs Contact Cover additional and is contained in schematic diagram on the carriage.

As shown in Figure 1, 2, the contact that main circuit connector of the present utility model is used has busbar (1) and the moving contact sheet (4) to adorning, and the two ends of one " C " shape spring (2) are crimped on the moving contact sheet of adorning (4).One pad (3) is clamped by three pairs of moving contact sheets (4), according to the size of operating current, also can adopt a pair of moving contact chip architecture, or two pairs, four the equity many to structure.The afterbody of moving contact sheet (4) is crimped on two sides of busbar (1).

Shown in Figure 10,11,12,13, the utility model also has a pair of Contact Cover (5) to dress when using, and the outside portion of the moving contact sheet (4) of dress is inlaid in the mounting groove (5-3) in the Contact Cover (5).Boss (5-1) on the Contact Cover (5) of dress is inserted in the connecting hole (1-1) of busbar (1).Has semi-circular boss (5-2) on the Contact Cover (5) to dress, semi-circular boss (5-2) inserts in the connecting hole (1-2) of busbar (1), and rivet (6) passes the cylindrical cavity that semi-circular boss (5-2) is contained, to the Contact Cover (5) of dress be riveted together with busbar (1), also can be without rivet (6), and tighten with hoop in Contact Cover (5) periphery.

Shown in Fig. 3,4,5, have two strip holes (2-1) on the side face of " C " shape spring (2) in the utility model, and as shown in Figure 1, 2, a pair of moving contact sheet (4) inserts respectively in these two strip holes (2-1), forms a clip shape.Shown in Fig. 6,7, the outside portion of moving contact sheet (4) has groove (4-1), and as shown in Figure 1, 2, two ends of " C " shape spring (2) are crimped on the groove (4-1).

Shown in Fig. 8,9, some blocks (3-1) are arranged on the pad (3), each keeps interfloor distance to being separated by block (3-1) between the moving contact sheet (4) shown in Fig. 2,11.Shown in Figure 10,11,12,13, the one side of pad (3) is resisted against on the side (5-7) of agproximation plate (5-6) of Contact Cover (5), and another side is resisted against on isolation bar (5-4) lower surface (5-5) in the Contact Cover (5), and this makes pad (3) keep the location.
