Abstract

The utility model relates to a wiring holder, which is clamped and connected by a fixed current conducting component arranged on the end of the screw. The wire holder is connected with a bracket, a circuit board, and a clamping board through screw bolts and screw nuts. The internal part of the circuit board is provided with a joint made of copper; the joint is a circular tube which is provided with a boss on the upper end; the middle of the boss is provided with an opening; the opening point is manufactured with a screw, and the screw point is screwed with a half-round head screw. Compared with the existing product, the wiring holder has the advantages of convenient operation and safe usage, and the wiring holder can eliminate the defects of large contact resistance of the existing product, easy generation of the oxidizing layer, the generation of the heating, combustion, etc.

Description

Junction block

The utility model relates to two above conductive electric wires and clamps the device that connects to realize or to keep to be in contact with one another, particularly a kind of with tip of screw fixedly electric-conductor the clamping connection,

Junction block is a kind of series of products, by the quantity that connects lead can be divided into the two wires, three-way ... multiple kind, can be divided into 16 peaces, 30 peaces, 60 peaces, 100 Anduo County kind specification again by electric current, it is the electric device that a kind of use has a large capacity and a wide range, existing junction block is made up of support, terminal block, clamping plate, screw rod, nut etc., lead is pressed on the last plane of terminal block with button-headed screw and pad, and last plane is surrounded by the steel pad.Such structure, electric current is by the steel pad by the copper lead, flow to another copper lead again, exist twice bronze medal one steel contact, the resistance at contact-making surface place is big, easily produce oxide skin, influence operate as normal, contact-making surface must be pressed very tightly in addition, and lead will be installed on screw, increased the screwing force of exposed length of lead and screw, made operation also inconvenient.

The purpose of this utility model is that a kind of contact of design is good, easy to operate junction block.

The purpose of this utility model realizes by following proposal, at the middle part of terminal block, embeds a joint made of copper, and joint is a upper end band boss, and the pipe of opening is arranged in the middle of the boss, and opening part is shaped on screw thread.It is fixed that the diameter of bore of pipe can come according to the diameter of wire of determining by current specification, and the screw thread place is screwed into button-headed screw and is used for compressing lead.

Accompanying drawing 1 is a structural representation of the present utility model.1 is support among the figure, and 2 is clamping plate, and 3 is terminal block, and 4 is joint, and 5 is button-headed screw, and 6 is cover plate, and 7 is nut, and 8 is packing ring, and 9 is screw rod.

Provide of the present utility model specifying in conjunction with the accompanying drawings.

The agent structure of the utility model junction block is by terminal block 3, clamping plate 2 and support 1, and by bolt 9, nut 7 and packing ring 8 are formed by connecting, the quantity of terminal block can be 2,3,4 ..., assembly forms as required.In terminal block, be embedded with joint 4, it can die casting in the terminal block of the system of moulding, it is mainly to contact conducting element, employing brass is made, it is shaped as the pipe just like the upper end band boss shown in the figure, opening is arranged in the middle of the boss, opening part is shaped on screw thread, and there is button-headed screw 5 at the screw thread place, inserts the lead that needs connection in the endoporus of pipe, so it is fixed that the diameter of endoporus can come according to the diameter of wire of determining by current specification, generally be slightly larger than diameter of wire, behind the lead patchhole, tighten button-headed screw 5 again, to compress lead, cover cover plate 6 at last.

The utility model junction block is compared with existing product to have easy to operately, uses safety Reliably, owing to improved the contact structures of lead, eliminated the contact resistance of existing product Easily produce oxide layer and cause heating, the shortcomings such as burning greatly.

Claims

1. junction block, it is made up of bolt, the nut of support, terminal block, clamping plate and connection, it is characterized in that setting-in one copper joint in terminal block, joint is the pipe of a upper end band boss, in the middle of the boss opening is arranged, opening part is shaped on screw thread, and the screw thread place is screwed with button-headed screw.
