Abstract

The utility model belongs to a low-voltage power transmission and distribution device and relates to a bus plug structure for branch lines of an illuminating bus, in particular to a plug pin of the illuminating bus. The plug pin of the illuminating bus comprises a pair of contact sheets, the rear ends of which are fixedly connected into a whole by a connecting plate, the two contact sheets and the connecting plate are punched and molded by a conductive sheet; the front sections of the two contact sheets spread outwards, thus forming an inserting and connecting groove as the inserting and matching section for being connected with the bus conductor, the cross sections of the contact sheets are of an arc shape which arches inwards; the middle sections of the two contact sheets are attached to each other and are opened with a through hole which penetrates through the two contact sheets, and a U-shaped spring wire runs through the through hole and is clamped at the outside of the front sections of the two contact sheets. The plug pin of the illuminating bus has simple structure and convenient manufacturing, by being matched with the spring wire and the arc part of the contact sheets, steady contact pressured can be supplied to the inserting and matching part of the contact sheets and the bus conductor, and the device can prevent the contact sheets from deforming, and the reliability of conductive contact can be increased.

Description

Illumination bus plug base pin

Technical field

The utility model belongs to the low pressure equipment for power transmission and distribution, relates to a kind of bus plug construction of the busbar branches wiring that is used to throw light on, and specifically is a kind of illumination bus plug base pin.

Background technology

Illumination bus plug is to be used to throw light on the device of busbar branches wiring, and it generally comprises housing and is installed in pin on the housing, and it is conductively connected by pin and bus-bars conductor and touches.Existing bus plug base pin is general to rely on the elasticity of leading pin conductor itself to guarantee to conduct electricity the contact pressure of contact, contacts unreliablely because of the distortion of conductor causes easily, influences the normal operation of equipment.

Summary of the invention

Technical problem to be solved in the utility model is, provides that a place is simple in structure, not yielding, the high illumination bus plug base pin of conduction contact reliability.

Illumination bus plug base pin of the present utility model includes a pair of contact, and the rear end of contact is connected to one by connecting plate, and two contacts and connecting plate are by a conductive sheet stamping-out and moulding; The leading portion of two contacts outwards opens the formation inserting groove, cooperates section as the grafting that is connected with bus-bars conductor, and the cross section of contact is the arc that arches upward to the inside; Fitting mutually in the stage casing of two contacts, and has a through hole that runs through two contacts, has the spring silk of a U-shaped to pass described through hole and be clipped in the outside of two contact leading portions.

Also extend one section installation sheet on the described connecting plate, have on the installation sheet and be used for the installing hole that is connected with plug casing or inner conductor.

The utility model is simple in structure, easily manufactured, by cooperating of spring silk and contact arch section, can provide the stable pressure that contacts to the contact and the grafting mating part of bus-bars conductor, can prevent the contact distortion, has improved the reliability of conduction contact.

Perspective view when Fig. 4 is the utility model embodiment and bus-bars conductor grafting.

The specific embodiment

As shown in Figure 1-Figure 3, comprise among the embodiment of the present utility model a pair of contact 1, connect two contacts connecting plate 2, form by extended installing plate 3 of connecting plate and the spring silk 4 that is clipped in the contact both sides.Described contact 1, connecting plate 2 and installing plate 3 are as a whole, and it is by a conductive sheet stamping-out and moulding.Contact 1 rear end connects by connecting plate 2; The contact leading portion outwards opens and forms the inserting groove of pegging graft and cooperating with bus-bars conductor, and the cross sectional shape of contact leading portion is an arc; Two contact stage casings fit and have through hole 5, and the spring silk 4 of U-shaped passes from through hole and is pressed in the arc-shaped recess part of two contact leading portions from the outside.

As shown in Figure 4, when the utility model and bus-bars conductor 6 socket connections, the arc surface of contact 1 inboard is pressed on the bus-bars conductor, and spring silk 4 is again from outer side compression two contacts.
