Description
Technical Field
The utility model belongs to the technical field of binding post for the cable, specifically speaking is a binding post that can eliminate stress.
Background
The connecting terminal is a common accessory product for realizing the connection of electric and cable, and is industrially divided into the category of connectors. In the cable construction production, the conducting cables of the cables with the voltage of more than 10KV are connected and fixed by adopting the wiring terminals.
At present, the connection mode of a single-core cable of 10kV or more is directly in compression joint with a copper nose, and then the installation surface of the copper nose is connected with the copper bar installation surface in a hole-to-hole mode. However, in the actual construction process, the 10kV single-core cable is thick and hard, so that the hole fixing is difficult to realize after direct compression joint, and the problem of large stress can be caused even if the cable is reluctantly fixed. For this reason, the existing terminal structure for cables is yet to be further improved.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome not enough among the prior art, provide a but binding post of stress relief, have simple structure, fixed convenience of cable crimping and characteristics such as effectual with the stress relief, can extensively be used for technical field such as power cable construction.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a wiring terminal capable of eliminating stress comprises a clamp, wherein a crimping terminal is arranged inside the clamp; the crimping terminal is of a cylindrical structure, and a pressure head is arranged at the top of the crimping terminal; the fixture is fixed on the copper bar, and the copper bar is fixedly connected to the insulating plate.
As an improvement, the clamp consists of two square plates made of brass and is provided with two bolts for connecting and fixing.
As an improvement, the inside of the jig is provided with a cylindrical through hole for placing and fixing the crimp terminal.
As an improvement, the top end of the pressure head is provided with a fillet, and an arc groove is arranged below the fillet.
As an improvement, the diameter of the indenter is 30% to 50% larger than the diameter of the crimp terminal.
As an improvement, the clamp is fixed on the copper bar through a buckle structure.
As an improvement, the crimping terminal is made of red copper and machined by a lathe.
The utility model discloses the beneficial effect who gains does: a wiring terminal capable of eliminating stress has the characteristics of simple structure, convenient cable crimping and fixing, good stress eliminating effect and the like; the cable is connected to the crimping terminal in a crimping mode through the crimping terminal with the pressure head structure, and then is fixedly connected through the two-piece type brass clamp, so that the cable is more convenient to connect and fix, the hole aligning difficulty is avoided, and meanwhile the problem of the connection stress of a single-core cable of 10kV or more is effectively solved; the rounded corners and the arc grooves are arranged at the top end of the pressure head, so that thick and hard cables can be conveniently sleeved, and the installation efficiency of construction is improved; in addition, the crimping terminal made of red copper is machined by a lathe, so that the strength and the size precision of the crimping terminal are improved, and the service life of the wiring terminal is prolonged.
Drawings
Fig. 1 is a schematic structural diagram of the terminal capable of eliminating stress according to the present invention.
In the figure: 1. anchor clamps, 2, crimping terminal, 3, pressure head, 4, copper bar, 5, insulation board, 6, bolt.
Detailed Description
The present invention will be described in further detail with reference to the following drawings and embodiments: as shown in fig. 1, the terminal capable of eliminating stress of the present invention includes a clamp 1, wherein a crimping terminal 2 is disposed inside the clamp 1; the crimping terminal 2 is of a cylindrical structure, and a pressure head 3 is arranged at the top of the crimping terminal; the fixture 1 is fixed on the copper bar 4, and the copper bar 4 is fixedly connected to the insulating plate 5.
Further, the clamp 1 is composed of two square plates made of brass and is provided with two bolts 6 which are fixedly connected; specifically, the bolt 6 fixedly connects the two brass square plates through a thread tapped inside the clamp 1, and fixes the crimping terminal 2 inside the clamp; further, the jig 1 is provided inside with a cylindrical through hole for placing and fixing the crimp terminal 2; specifically, cylindrical through-hole comprises two square boards, and is more specific, cylindrical through-hole forms through machining earlier, and rethread line cutting becomes two square boards half to guarantee that through-hole diameter size is accurate.
Furthermore, a fillet is arranged at the top end of the pressure head 3, and an arc groove is arranged below the fillet, so that a thick and hard cable can be conveniently sleeved, and the installation efficiency of construction is improved; furthermore, the diameter of the pressing head 3 is 30% -50%, preferably 35% -45% larger than that of the crimping terminal 2, so that the material cost is reduced while the crimping terminal 2 is prevented from sliding off.
Further, anchor clamps 1 is fixed in through buckle structure on the copper bar 4, it is concrete, adopt the recess buckle mode to fix to it is more convenient, swift to install.
Further, the crimping terminal 2 is made of red copper and is machined through a lathe, so that the strength and the size precision of the crimping terminal are improved, and the service life of the wiring terminal is prolonged.
The utility model discloses a binding post that can eliminate stress has simple structure, the fixed convenience of cable crimping and characteristics such as effectual with the stress relief, through adopting the structure that sets up two formula brass anchor clamps 1 of halving, cooperates red copper's crimping terminal 2 simultaneously, adopts the crimping mode to be connected through the crimping terminal 2 with 10kV single core cable and red copper, is connected with brass anchor clamps 1 again to the difficult and connection stress problem of connecting of 10kV single core cable has been solved.
Finally, it should be noted that the above-mentioned list is only a specific embodiment of the present invention. Obviously, the present invention is not limited to the above embodiments, and many variations are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the present invention should be considered as within the scope of the present invention.
