Abstract

The utility model designs a bus wire connector that joint units can be connected with each other by the bus wire connector and the joint points are fully shielded, insulated, sealed and protected after connecting. The bus wire connector has compact and reasonable structure, and superb expansibility together with excellent insulating property and discharge current capability. The utility model comprises bus wires and bus wire copper rods. The bus wires are engaged on the body of the bus wire copper rod and both exerted ends of the bus wire copper rod equals in size, thereby forming the bus wire connector. The bus wires are made from rubber insulating materials and equipped with a reasonably designed stress cone inside, thereby evenly distributing complexly distributive electric field, which have excellent performances and long service life. The bus wire copper rod is equipped with spring sensing finger (watch chain), and with excellent elasticity and large contact face, thereby guaranteeing the discharge current capability of the electrical conductor.

Description

Bus tie

Technical field:

The utility model relates to the link-bus tie of a kind of cable distribution system center tap body unit.

Background technology:

The quality of connection of cable distribution system center tap body unit directly influences the fail safe and the reliability of cable distribution system hanging net operation.The fittings body unit is the rubber prefabricated component of tyre closed metal structure, for conveniently splicing and ensuring the quality of products, requires to splice on the level ground.After the splicing of fittings body unit, should guarantee its compact conformation, reasonable, the necessary full-shield in junction, all insulation, hermetically sealed, full protection, simultaneously, the insulation property and the through-current capability that also should have good autgmentability, excellence, so the structural design of bus tie is one of key that influences cable distribution mass of system quality, but existing technology is difficult to address this problem.

Summary of the invention:

The purpose of this utility model is to change the deficiencies in the prior art part, design a kind of bus tie, the fittings body unit can splice by it, fittings body unit after the splicing, it connects part full-shield, all insulation, hermetically sealed, full protection, compact conformation, reasonable, autgmentability is fabulous, has excellent insulation property and through-current capability simultaneously.

For achieving the above object, the technical scheme that the utility model provides is: mainly include bus and bus copper rod, bus is set on the barred body of bus copper rod, and two exposed junction area of bed equities of bus copper rod just form bus tie, and bus adopts the rubber insulation material manufacturing, in the stress cone of appropriate design is arranged, evenly the electric field of complex distributions, excellent performance, long service life; Spring touch finger (watch chain) is housed on the bus copper rod, good springiness, contact-making surface is big, has guaranteed the through-current capability of conductor.

After the utility model adopts said structure, the connection of fittings body unit is among full-shield, all insulation, hermetically sealed, the full protection, simplified the connectivity problem of fittings body unit greatly, compact conformation, reasonable, autgmentability is fabulous, have excellent insulation property and through-flow performance simultaneously, guaranteed the stable, safe and reliable of cable distribution system.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model

Accompanying drawing 2 is applied to the structural representation that the fittings body unit connects for the utility model

Accompanying drawing 3A, accompanying drawing 3B are that the utility model is applied to the schematic appearance that the fittings body unit connects

Embodiment:

Below in conjunction with a preferred embodiment and accompanying drawing thereof the utility model is described further.

As shown in Figure 1, present embodiment mainly includes bus 1 and bus copper rod 2, bus copper rod 2 is passed bus 1, equity two ends size, just form bus tie (seeing shown in the accompanying drawing 1), bus 1 adopts the manufacturing of special silicone rubber insulating material, in the stress cone of appropriate design is arranged, spring touch finger 3 (watch chain) is housed on the bus copper rod 2.After the utility model was taked above structure, the fittings body unit had fabulous autgmentability.

See shown in accompanying drawing 2, accompanying drawing 3A, the accompanying drawing 3B, when the fittings body unit need splice, utilize orientation tool, earlier bus tie A is inserted in the connecting hole of one of them fittings body unit B, install to the position, then another fittings body unit C being aimed at bus tie A cover is loaded into, utilize the flange hole on fittings body unit B, the C metal shell at last, with screw 4 two fittings body unit are close to together and (see shown in accompanying drawing 2, accompanying drawing 3A, the accompanying drawing 3B, represent two fittings body unit having connected among Fig. 2, and be reserved with the expansion connector; Fig. 3 A, 3B have represented the outside drawing of two fittings body unit having connected).Connect a fittings body unit if desired again, repeat aforesaid operations and get final product.

The embodiment of the above only is preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; so all equivalences of doing according to shape of the present utility model, structure and principle change, and all should be covered by within the protection range of the present utility model.
