Abstract

A connecting terminal comprises a plastic sleeve (1) and a hollow iron conductive tube (2) which is penetrated in the sleeve, wherein wires can be penetrated in the conductive tube (2). The characteristic is that the edge position (24) of the conductive tube which is contacted with the wires is adopted with composite copper material. The conductive tube which is used to connect wires in the utility model adopts the composite material, namely that the whole conductive tube adopts iron material, and the part on the edges of the conductive tube which is contacted with the wires adopts partial composite copper material, thus the whole conductive tube which adopts iron material has high strength and low cost, and the contact part with the wires which adopts the copper material has conductivity property. The conductive tube adopts the composite copper material, and replaces the copper piece structure which is originally punched, therefore which has high reliability on conductivity copper material part and free dropping copper, saves cost when the punching difficulty is reduced, and is more suitable to be produced in batch.

Description

A kind of binding post

Technical field

The utility model relates to a kind of binding post that is used to connect the electric equipment conductor wire.

Background technology

In order to save cost, the binding post of traditional employing integral type copper pipe structure, change into now in the contact tube bottom and be lined with copper conducting strip, the contact tube body part then adopts ferrous material, if any the patent No. is that the Chinese utility model " structure of the terminal board of improvement " of ZL200420058417.5 discloses a kind of such binding post, and its contact tube is the irony structure, and its bottom is made as circular-arc, it is copper structure that inner root edge is equipped with a conducting strip, can save copper material like this.But copper current-conducting piece is to pass through die process in the above-mentioned patent, utilize the mode of punching press that conducting strip and contact tube are riveted together, the copper conducting strip of this technology mode is loosening easily, poor reliability, and the punching press difficulty is big, has increased production cost again from another point of view.Therefore, await to do further improvement.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of conduction reliability height, technology simple relatively binding post at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this binding post, include the irony contact tube of plastic sleeve and hollow, conductor wire can be located in the described contact tube, it is characterized in that: described contact tube adopts the complex copper material at the root edge position that contacts with conductor wire.

Described sleeve has more piece, and forms a plastics communicating pipe that multichannel is through, and every joint sleeve is being provided with two and can holding the threaded hole that bolt/screw is passed of symmetry all, and sleeve adopts plastics, can play the effect to external insulation and protection contact tube.

Described contact tube is being provided with the screwed hole that can supply described bolt/screw to pass with the corresponding position of described threaded hole, when installation and removal, can be with bolt/screw through threaded hole up and down turn in screwed hole, and then compress or loosen conductor wire in the contact tube.

Compared with prior art, advantage of the present utility model is: the contact tube that connects conductor wire has adopted novel composite material, it is the whole ferrous material that adopts of contact tube, and adopt local compound copper material in the part of what lead contact of contact tube root edge, so, contact tube is whole because adopt iron material, and intensity height, cost are low, and in the contact that contacts with conductor wire partly because used copper material, have conductivity; Because adopted compound copper material, replaced original stamping forming copper sheet structure again, conduction copper material position reliability height, the copper difficult drop-off has been saved cost when reducing the punching press difficulty, be more suitable for producing in enormous quantities.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1～binding post shown in Figure 4, it comprises the plastics communicating pipe (present embodiment only provides two joint sleeves wherein) that has more piece sleeve 1 and connect, and irony contact tube 2 with hollow channel 21, wherein, every joint sleeve 1 is with square siphunculus 11, all being provided with two on the sleeve 1 symmetrically can cooperate with screw 3, threaded hole 13 with protruding neck 12, correspondingly, two screwed holes 22 that on each contact tube 2, have threaded hole 13 correspondences of two and this joint sleeve 1, each screwed hole 22 top has boss 23, conductor wire can insert in the hollow channel 21 of contact tube, and available screw 4 compresses through the conductor wire that threaded hole 12 and screwed hole 21 will penetrate in the contact tube 2; And the bottom of contact tube 2 is curved, and the contact tube 2 whole main ferrous materials that adopt have adopted the complex copper material as conducting strip 4 at the root edge position 24 that described contact tube contacts with conductor wire.

In use, as long as conductor wire is inserted in the hollow pipeline of contact tube, conductor wire is pressed on the position that is compounded with copper product of described contact tube root edge with screw, then promptly can constitute the conducting of power supply or signal, in order to prevent the conductor wire mutually noninterfere in the adjacent screwed hole, also be provided with stamping forming catch 5 at the medium position of contact tube.Because replaced original needs to be stamped into the copper sheet structure of electrically conducting contact position with compound copper material in the contact tube, conducting position is more reliable, the copper difficult drop-off, thus guaranteed the reliability of line work.

Claims

1, a kind of binding post, include plastic sleeve (1) and be located in the interior hollow irony contact tube (2) of sleeve, conductor wire can be located in the described contact tube (2), it is characterized in that: described contact tube (2) adopts the complex copper material at the root edge position (24) that contacts with conductor wire.

2, binding post as claimed in claim 1 is characterized in that: described sleeve (1) has more piece, and forms a plastics communicating pipe that multichannel is through, every joint sleeve (1) all symmetry be provided with two threaded hole (13).

3, binding post as claimed in claim 2 is characterized in that: described contact tube (2) has screwed hole (21) with the corresponding position of described threaded hole (13).
