Abstract
The utility model discloses a three hole aluminum alloy binding post, including casing and elastic element, the casing both ends are equipped with a cable opening, the upper end of casing is equipped with two screw holes, be equipped with a cable opening No. two that run through whole casing in the middle of two screw holes, be equipped with elastic element on the screw hole, elastic element and casing pass through the cooperation fixed connection between the screw thread. The utility model aims at providing a can prevent to take place not hard up because cable junction time has been of a specified duration easily to and prevent that binding post from taking place oxidation, sclerosis still circular telegram not good, the not good three hole aluminum alloy binding post of electric shock because operating time has lasted after easy.
Description
Technical Field
The utility model relates to a binding post field especially relates to a three hole aluminum alloy binding post.
Background
The connecting terminal is used for conveniently connecting the wires, and is actually a section of metal sheet sealed in insulating plastic, both ends of the metal sheet are provided with holes for inserting the wires, and screws are used for fastening or loosening, for example, two wires are connected at times and disconnected at times, and then the two wires can be connected by using the terminal and disconnected at any time without welding or winding the two wires together, so that convenience and rapidness are realized.
The conventional wiring terminal is generally a two-hole wiring terminal, the service performance is not high, the conventional wiring terminal is made of zinc alloy, the price is high, the joint electrifying efficiency is low, hardening is easy to occur after a period of use, and the service life and the practicability are low.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a: in order to solve the above problems, a three-hole aluminum alloy terminal is proposed.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a three hole aluminum alloy binding post, includes casing and elastic element, its characterized in that, the casing both ends are equipped with a cable opening, the upper end of casing is equipped with two screw holes, be equipped with a cable opening No. two that run through whole casing in the middle of two screw holes, be equipped with elastic element on the screw hole, elastic element and casing pass through the cooperation fixed connection between the screw thread.
Preferably, the three-hole aluminum alloy wiring terminal is characterized in that a pressing block is arranged at the lower end of the elastic element.
Preferably, the three-hole aluminum alloy wiring terminal is characterized in that a spring is arranged between the upper end of the pressing block and the shell.
Preferably, the three-hole aluminum alloy terminal is characterized in that the housing and the elastic element are both made of aluminum alloy materials.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:
1. the utility model discloses wholly adopt aluminum alloy material to make, compare in zinc alloy, the aluminum alloy price is lower to aluminum joint circular telegram efficiency is faster, and the effect of electrocution is better, and the aluminum alloy still has difficult sclerosis, the difficult characteristics of oxidation, very big improvement binding post's life.
2. The utility model discloses elastic element is the helicitic texture in the middle of for, mutually supports with the screw hole and the compact heap of casing, can play the effect of fastening to it in cable junction to directly set up the spring at casing and compact heap, the screw thread takes place easily not hard up in long-time, but after adding and establishing the spring, the spring can play the compensatory action to the screw thread, has improved binding post's practicality and life.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1 to 3, a three-hole aluminum alloy wiring terminal includes a housing 1 and an elastic element 2, and is characterized in that two ends of the housing 1 are provided with a first cable opening 5, the upper end of the housing 1 is provided with two threaded holes 3, a second cable opening 4 penetrating through the entire housing 1 is arranged between the two threaded holes 3, the threaded holes 3 are provided with the elastic element 2, and the elastic element 2 and the housing 1 are fixedly connected by matching between threads.
The elastic element 2 shown in fig. 1 and 2 is provided with a pressing block 6 at the lower end thereof for fastening the cable when the cable is connected.
A spring 7 is arranged between the upper end of the pressing block 6 and the shell 1 as shown in fig. 1 and 2, and can compensate the thread after the thread is worn, so that the service life of the connecting terminal is prolonged.
As shown in fig. 1 to 3, the housing 1 and the elastic element 2 are both made of an aluminum alloy material, and compared with a zinc alloy, the aluminum alloy material has the advantages of being not easy to harden, not easy to oxidize, high in current carrying capacity, high in torsion and the like, so that the service life of the wiring terminal is greatly prolonged.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
