Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment: a kind of connector for terminated high voltage electrical cables, as shown in Figure 1, including connector and reeve connector
The junction of two internal high-tension cables 9, high-tension cable 9 and connector is arranged with fixing clasp 7.
As shown in Fig. 2, connector includes the shell 1 of inner hollow, high-tension cable 9 protrudes into shell 1 from one end of shell 1
It is interior, shielding part 3 is fixed on the internal perisporium of shell 1, shielding part 3 is the cylindrical metal thin slice being attached on 1 internal perisporium of shell.Shell
It is further fixed on the insulation shell 8 positioned at 3 inside of shielding part in 1, is equipped with the terminal protruded into for high-tension cable 9 inside insulation shell 8
Slot is also housed within the connecting terminal 2 that one end is crimped on the inner conductor of high-tension cable 9 in terminal groove, and high-tension cable 9 is in terminal groove
It is interior to be in close contact with connecting terminal 2, and it is not susceptible to loose phenomenon.
One end that high-tension cable 9 is put in shell 1 is arranged with shielding connector 4, and shielding connector 4 is to lead in step-like
Electric metal piece shields 4 sets of connector one end in 9 periphery of high-tension cable and closely connect with the shielded layer of high-tension cable 9, and shielding connects
One end that fitting 4 extends outward is contacted with the shielding part 3 in shell 1, the shielded layer for making high-tension cable 9 and the shielding in shell 1
Part 3 comes into full contact with, and reduces influence of the electrical interference to connector reliability.
Periphery of 4 sets of the shielding connector in high-tension cable 9 tightens the crimp 5 for being cased with circular ring shape, and crimp 5 compresses shielding
To apply first to high-tension cable 9, radially inwardly on the one hand power, the setting of crimp 5 make to shield connector 4 and high pressure connector 4
The shielded layer of cable 9 comes into full contact with, and shielding properties is more preferable, on the other hand can clamp high-tension cable 9, is not easy high-tension cable 9
Loosen thus can be able to maintain with connecting terminal 2 and well contact.
Periphery of the high-tension cable 9 at the port holes of shell 1, which squeezes, is packed with sealing element 6, and sealing element 6 sets for periphery wall
There is the sealing ring of arc fin.The setting of sealing element 6 can prevent extraneous grease, dust from passing through between shell 1 and high-tension cable 9
Gap enters in the shell 1 of connector, improves the reliability of connector；In addition, sealing element 6 is extruded in the port holes of shell 1
After interior, capable of applying second to high-tension cable 9, radially inwardly power, high-tension cable 9 are just not easy out of shell 1 port holes sliding
Out, make the mounting structure of high-tension cable 9 and sealing element 6 more firm.
In conjunction with shown in Fig. 1 and Fig. 3, the port holes outer sheath of shell 1 is equipped with fixing clasp 7, and fixing clasp 7 includes being set in
Interior snap ring 71 on the outside of the port holes of shell 1 and the outer snap ring 72 on high-tension cable 9 is covered, 71 one of outer snap ring 72 and interior snap ring
Molding, and the cross-sectional area of outer snap ring 72 is less than the cross-sectional area of interior snap ring 71.Outer snap ring 72 is by shell 1 to high-tension cable 9
The radial force of port holes inner part application inwardly is put in, interior snap ring 71 is located at the part outside port holes to high-tension cable 9 and applies court
Interior active force makes high-tension cable 9 be not easy to be pulled out along its axial direction, to make between high-tension cable 9 and connecting terminal 2 not
Easily there is loose phenomenon, the reliability of connector is higher.
With reference to Fig. 3, limit card slot 711, the notch direction of limit card slot 711 and high-tension cable 9 are offered on interior snap ring 71
Plug orientation, integrally formed with buckle 11 on the periphery wall at 1 port holes of shell, fixing clasp 7 is mounted on 1 port holes of shell
After periphery, the buckle 11 on shell 1 is put in the limit card slot 711 of interior snap ring 71, makes the mounting structure of fixing clasp 7 more
It is firm, and then ensure the fastness of connection structure between high-tension cable 9 and shell 1.
Offer two notches 712 positioned at 711 two sides of limit card slot on interior snap ring 71, the opening direction of notch 712 with
The opening direction of limit card slot 711 is opposite.Notch 712 can be such that interior snap ring 71 becomes in the structural strength of 711 vicinity of limit card slot
It is low, it deforms the interior snap ring 71 near limit card slot 711 relatively easily, is imported in limit card slot 711 convenient for buckle 11.
Buckle 11 is equipped with oblique surface 111, in the process that interior snap ring 71 is packed into shell 1 along the axial direction of port holes
In, it is more convenient, it is not easy internal snap ring 71 and causes to damage.
The course of work and principle: after high-tension cable 9 is put in connector shell 1, crimp 5 applies high-tension cable 9
First radially inwardly power, sealing element 6 apply high-tension cable 9 while playing gap between 1 port holes of sealing shell and high-tension cable 9
Add the second radially inwardly power, fixing clasp 7 applies third radially inwardly power to high-tension cable 9 by shell 1 and sealing element 6, leads to
The mode that high-tension cable 9 is fixed in excessive heavy dressing power is able to maintain high-tension cable 9 with connecting terminal 2 and contacts good, raising
The reliability of connector.In addition, shielding connector 4 contacts the shielded layer of high-tension cable 9 with the shielding part 3 in shell 1, prevent
Only high-tension cable 9 emits electrical interference or prevents electrical interference from entering in high voltage cable, further improves the reliability of connector.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
