Description
Technical field
The utility model relates to a kind of cable locking heads.
Background technique
Integrated form controller is the maincenter of vehicle high-pressure system in electric car, is mainly used for the high-tension current of vehicle
It is assigned to different high voltage electric units, so that electric drive motor, steering, air compressor machine and DCDC work are provided, it is whole to guaranteeing
Vehicle reliability service plays central role.Integrated form controller is connect by power high-voltage line with execution unit, and power is provided, and is executed
Component, which goes wrong, to need repairing when replacing, and often relates to the dismounting of power high-voltage wiring harness.High-voltage wiring harness and integrated form control at present
The locking of device processed connects as shown in Figure 1, the conducting wire in cable 3 is connect with the terminals in controller 1, and then locking head 2 screws
In cable perforation on controller housing, so that cable 3 is locked on the controller.Specifically, the structure of locking head 2
As shown in Fig. 2, including locking nut 20, the two sides of locking nut 20 are provided with the first thread segment 21 and the second thread segment 22, the
One thread segment 21 is used to perforate with cable and connect, and the end face of locking nut 20 perforated towards cable can be with line upon connection
The hole of cable perforation is installed with tail portion nut 23 along the second thread segment 22 along sealing is compressed, which can will be outside cable
Skin holds sealing tightly.
However, using this locking connection type when taking out stitches more have inconvenience.When taking out stitches, need to unscrew tail portion by spanner
Nut 23 from controller so that dismantle cable, since tail portion nut 23 is not only screwed with the second thread segment 22, and also and cable
Crust is held tightly, and do not unscrew tail portion nut 23 toward contact when taking out stitches just will revolve between the first thread segment 21 and cable perforation
Pine, as shown in figure 3, result in locking head 2 to remove from controller 1 together with cable 3 in this way, at this time again by tail portion nut 23 from
It is just more inconvenient to remove on second thread segment 22, causes very burden to the process of taking out stitches.
Utility model content
The purpose of this utility model is to provide a kind of cable locking head, take out stitches inconvenience to solve existing locking head
The problem of.
The cable locking head of the utility model includes locking nut and tail portion nut, and the both ends of locking nut are respectively equipped with
One thread segment and the second thread segment, locking nut inside are equipped with axial through bore, and tail portion nut spinning is on the second thread segment, locking
It is convex along holding out against that the end face backwards to tail portion nut of nut is equipped with hole that is axially extending, being used to perforate with cable when in use
It rises.
The cable locking head of the utility model is convex when sealing locking nut screwing along compression with the hole of cable perforation
The hole perforated with cable is played along holding out against, in addition to screwing power at the first thread segment between locking nut and hole edge, also passes through protrusion
Biggish frictional force is generated between cable perforation, in this way when dismantling tail portion nut, can be guaranteed in tail portion nut from second
When unscrewing on thread segment, locking nut is still perforated with cable locking connection, can easily realize cable and tail portion nut it
Between disassembly.
Further, in order to increase frictional force of the hole of locking nut and cable perforation between, the protrusion has multiple
And it is arranged circumferentially around the axis of locking nut.
In order to avoid protrusion and the sealing structure in cable perforation interfere, the protrusion is located at the hexagonal of locking nut
Position.
Protrusion structure type can there are many, it is preferable that it is described protrusion be spur structure, screwing locking nut in this way
When, locking nut and the hole that cable is perforated are tighter along what is be engaged.
Specifically, spur structure is located at the hexagonal position of locking nut, and spur structure can be the back of processing locking nut
The arc spur rearwardly reserved when the end face of nut.

Specific embodiment
The embodiments of the present invention is described further with reference to the accompanying drawing.
The embodiment of the cable locking head of the utility model, as shown in Fig. 4 ~ 5, including locking nut 20, locking nut 20
Two sides be respectively equipped with the first thread segment 21 and the second thread segment 22, be equipped with inside locking nut 20 axially through the first screw thread
The axial through bore of section 21 and the second thread segment 22.Wherein, it is installed with tail portion nut 23 on the second thread segment 22, tail portion nut 23
Inside is again provided with axial through bore.
In use, cable passed through from the axial through bore of tail portion nut 23 and locking nut 20 and in connecting part
Terminals connection, locking nut 20 locks connection with to the cable perforation on connecting part by the first thread segment 21, and passes through
The gasket of its end face 200 and the hole of cable perforation at, which compresses, to be sealed；Then tail portion nut 23 is screwed, tail portion spiral shell can be passed through
Cap 23 holds cable tightly, ensure that the sealing of cable tail portion.
Locking nut 20 is additionally provided with protrusion 201 on the end face 200 of tail portion nut 23, is tightened on by locking nut 20
When in cable perforation, protrusion 201 can be pressed on the hole of cable perforation along upper, to increase locking nut 20 and cable perforates it
Between coupling mechanism force.
Specifically, there are six protrusions 201, and it is respectively at the hexagonal position of locking nut 20, it is preferable that protrusion is spur
Structure, spur structure arc spur reserved when can be the end face 200 of processing (turning or milling) locking nut.
In this way, when sealing locking nut screwing along compression with the hole of cable perforation, the hole of protrusion and cable perforation
Along holding out against, in addition to screwing power at the first thread segment between locking nut and hole edge, also by being produced between protrusion and cable perforation
Raw biggish frictional force can guarantee in this way when dismantling tail portion nut when tail portion nut is unscrewed from the second thread segment, lock
Tight nut, which is still perforated with cable, locks connection, can easily realize the disassembly between cable and tail portion nut.
Certainly, the cable locking head of the utility model is not limited in above-mentioned embodiment.
Such as in other embodiments, protrusion can be the protrusion or hemisphere jut or taper spur etc. of end-tooth shape；
For the locking nut of hexagonal, raised number may be three or two, and at the angle in locking nut；Alternatively,
Not in the case where interference seal, protrusion can also be located at position between the two corners of hexagon locking nut.
