Abstract
The utility model belongs to the cable accessory field and especially relates to a hollow self-cooling branch-cable special-purpose wiring terminal, comprising a tube part, a board part and a transition part, wherein the tube part and the board part are connected by the transition part. A tube inner hole is mounted inside of the tube part. A board hole is disposed on the board part. The branch-cable special-purpose wiring terminal is characterized in that a ventilating opening is arranged on the transition part and communicates the ventilating opening with an environment, a conductor is mounted in the tube inner hole, and a distance between a hole wall of the tube inner hole and conductor external diameter is 0.3-0.5 mm. The utility model provides the hollow self-cooling branch-cable special-purpose wiring terminal which is simple in a structure and is easy to manufacture and popularize.
Description
Technical field
The utility model belongs to the electric cable accessories field, relates in particular to a kind of cable connecting terminal.
Background technology
Binding post is a kind of in low-voltage power system, and cable is connected with equipment end to continue the electric cable accessories of conduct power, is widely used in the industries such as illumination, communication, security protection.At present, the self cooling branch cable of hollow does not have special-purpose cable connecting terminal, because traditional cable connecting terminal adopts sealing crimping form, and the self cooling branch cable of hollow can produce certain heat in galvanization, traditional cable connecting terminal can't satisfy the required inner ventilation requirement of the self cooling branch cable of hollow, the cooling rate of the self cooling branch cable of hollow that slowed down; In addition, the conductor diameter of the self cooling branch cable of hollow is greater than the conductor diameter of traditional cable, in actual use, gap between the pipe orifice hole wall of the conductor of the self cooling branch cable of hollow and binding post is larger, contact area is less, the self cooling branch cable of hollow produces superheating phenomenon easily, and therefore, the self cooling branch cable of hollow is difficult to support the use with traditional cable connecting terminal.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of hollow self cooling branch cable special wiring terminal, comprise pipe section, board, transition part, described pipe section be connected board and connect by described transition part, described pipe section inside is provided with pipe orifice, be provided with plate hole on the described board, it is characterized in that: described transition part is provided with ventilating opening, described ventilating opening is in communication with the outside described pipe orifice, be placed with conductor in the described pipe orifice, the distance between the hole wall of described pipe orifice and the described conductor diameter is 0.3-0.5mm.
The internal diameter of described ventilating opening is 9-13mm.
The beneficial effects of the utility model are: set up ventilating opening on the transition part, ventilating opening is in communication with the outside pipe orifice, is convenient to circulation of air, promotes the self cooling branch cable of hollow to ventilate, and accelerates the self cooling branch cable cooling of hollow; Hole wall and the distance between the conductor diameter of pipe orifice are 0.3-0.5mm, reduce the internal diameter gap of conductor diameter and binding post, have alleviated the superheating phenomenon that produces because contact area is less between binding post and the conductor.It is a kind of simple in structure that the utility model provides, and is easy to make the self cooling branch cable special wiring terminal of hollow of popularization.
Description of drawings

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Among the figure, 1-pipe section, 2-board, 3-transition part, 4-pipe orifice, 5-plate hole, 6-ventilating opening, 7-conductor.
Embodiment
Shown in Fig. 1-2, pipe section 1 is connected with board by transition part 3 connections, pipe section 1 inside is provided with pipe orifice 4, be provided with plate hole 5 on the board 2, transition part 3 is provided with the ventilating opening 6 that internal diameter is 9-13mm, ventilating opening 6 pipe orifice 4 is in communication with the outside is placed with conductor 7 in the pipe orifice 4, the distance between the hole wall of pipe orifice 4 and conductor 7 external diameters is 0.3-0.5mm.
Make use-case
Shown in Fig. 1-2, during use cable being pressed construction requirement processes, cable conductor 7 is inserted in the pipe orifice 4 of pipe section 1, aluminium hydraulic pressed connecting pipe section 1, after crimping is finished, the link of equipment and board 2 closely are connected by bolt, ventilating opening 6 is in communication with the outside pipe orifice 4, promote the self cooling branch cable of hollow to ventilate, accelerate the self cooling branch cable cooling of hollow, distance between the hole wall of pipe orifice 4 and conductor 7 external diameters is 0.3-0.5mm, reduces the internal diameter gap of conductor 7 external diameters and binding post, has alleviated the superheating phenomenon that produces because contact area is less between binding post and the conductor 7.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
