End is C-shaped ring.
The utility model, which further improves, to be, when use state, is further included double threaded screw, is threaded through elbow-type head
On insulating sleeve, and double threaded screw passes through broadening formation through-hole and is sleeved in terminal body.
The utility model, which further improves, to be, the middle part of the double threaded screw is equipped with the shaft shoulder, the shaft shoulder and broadening formation
Through hole contact.
The utility model, which further improves, to be, which is made of T2 copper product.
The utility model, which further improves, to be, the surface of the terminal body is coated with one layer of tin metal.
The utility model, which further improves, to be, it is logical that broadening formation through-hole can replace with the circle in conventional type terminal
Gasket is added in hole.
The utility model has following beneficial technical effect:
In product installation, after conventional type terminal is crimped with cable completion, when separable connector is pressed into insulating sleeve,
The cooperation of diameter progressive screw and terminal is it is possible that leftward or rightward eccentric situation under the weight bearing of cable.The utility model mentions
A kind of ring network cabinet elbow-type head horn mouth terminal supplied, the broadening formation terminal are then not in such situation when product is installed.
Broadening formation terminal center and double threaded screw central coaxial, therefore increase the contact area of broadening formation terminal and double threaded screw
(passage section), can be increased current-carrying capacity, reduce the fever of terminal, it is ensured that connect after installation reliable.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 3 and Figure 4, a kind of ring network cabinet elbow-type head broadening formation terminal provided by the utility model, including terminal
Ontology 1, and the broadening formation through-hole 2 in terminal body 1 is provided with perpendicular to the axial direction of the terminal body 1.Wherein, the terminal
The overall structure of ontology 1 is in Y type, is C-shaped ring in one end opposite with the broadening formation through-hole 2 opened up in the terminal body 1.Make
It further include double threaded screw 3 when with state, the middle part of the double threaded screw 3 is equipped with the shaft shoulder, is threaded through the insulating sleeve 6 of elbow-type head
On, and double threaded screw 3 passes through broadening formation through-hole 2 and is sleeved in terminal body 1, the shaft shoulder and broadening formation of double threaded screw 3
It is contacted at through-hole 2.
Preferably, which is made of T2 copper product, and surface is coated with one layer of tin metal.
Parameters variation carries out following illustrate before and after being retrofited below for certain unit 10kV separable connector with terminal:
If conventional type terminal 7 and the contact area of cored screw 3 are about 1, after the installation of 10kV separable connector
375mm2, as depicted in figs. 1 and 2.
2, the contact area of remodeling rear terminal and cored screw 3 is about 472mm2(150mm2)、460mm2(300mm2), because
This increases the contact area (passage section) of terminal Yu cored screw 3, can be increased current-carrying capacity, reduces the fever of terminal, such as
Shown in Fig. 3 and Fig. 4.
4, when product is installed, after conventional type terminal 7 is crimped with cable completion, separable connector is pressed into insulating sleeve
When 6, due to being provided with circular through hole 4, the cooperation of double threaded screw 3 and terminal is it is possible that the left or to the right under the weight bearing of cable
Eccentric situation, as shown in Figure 5.Terminal after remodeling is then not in such situation when product is installed.Make terminal center with
3 central coaxial of double threaded screw, it is ensured that connected reliably after installation, avoid the abnormal heating of setting-up eccentricity, as shown in Figure 6.
It 5, can also be in terminal because terminal inner hole can not be modified for the terminal that installation (crimping) is completed
Inner hole increases gasket 5, and effect is consistent with the terminal after remodeling, as shown in Figure 7 and Figure 8.
