a stop collar for electrical connector cable spacing comprising: the spacing body, spacing body both ends all are provided with and press from both sides tight sheath, and the one end of pressing from both sides tight sheath free end is provided with the locking pin, and the other end of free end is provided with the locking hole.

As the preferred scheme, the stop collar adopts an integrated structure.

Preferably, the limiting sleeve is made of elastic materials.

Preferably, the inner wall of the clamping sheath is provided with a limiting piece for preventing the cable from sliding along the central shaft.

Preferably, the distance body is provided with a weight-reducing through hole.

As the preferred scheme, the locking pin comprises a connecting body, a pin cylinder body is arranged on the connecting body, a guide body is arranged at the free end of the pin cylinder body, a guide inclined plane is arranged on the side face of the guide body, the base angle of the guide body is set to be an R angle, an avoiding cavity is arranged in the pin cylinder body, and an included angle between the pin cylinder body and the connecting body is set to be the R angle.

As the preferred scheme, the locking hole comprises a connecting body, a locking through hole is arranged in the connecting body, and a guide inclined plane is arranged at the front end of the locking through hole.

Preferably, the locking pins at two ends of the spacing body are arranged vertically and oppositely and horizontally and oppositely.

Has the advantages that: the utility model provides a pair of a stop collar for electric connector cable interval, stop collar adopt integral type rubber construction, simple structure, and easy to assemble dismantles. Can effectively carry out spacingly to the cable interval to the wobbling plug of automobile body when the operation.

Detailed Description

The present invention will be further described with reference to the following specific embodiments.

Example 1:

as shown in fig. 1, a spacing sleeve for an electric connector cable spacing is provided, wherein one end of a spacing body 1 is provided with a first clamping sheath 2, the other end of the spacing body 1 is provided with a second clamping sheath 3, one end of the outer side of the free end of the first clamping sheath 1 is provided with a left locking pin 4, and one end of the inner side of the free end of the first clamping sheath 1 is provided with a left locking hole 5; one end of the outer side of the free end of the second clamping sheath 3 is provided with a right locking hole 6, and one end of the inner side of the free end of the second clamping sheath 5 is provided with a right locking pin 7.

Example 2:

the stop collar adopts the integrated into one piece structure of rubber material, is provided with in the body of interval and subtracts heavy through-hole 8.

Example 3:

as shown in fig. 2-3, the locking pin includes a connecting body 101, a pin cylinder 102 is disposed on the connecting body 101, a guide body 103 is disposed at a free end of the pin cylinder 102, a guide inclined surface 104 is disposed on a side surface of the guide body 103, a base angle of the guide body 103 is set to be an R angle 105, an avoiding cavity 106 is disposed in the pin cylinder 102, and an included angle between the pin cylinder 102 and the connecting body 101 is set to be the R angle 105.

The locking hole comprises a connecting body 101, a locking through hole 107 is arranged in the connecting body 101, and a guide inclined plane 104 is arranged at the front end of the locking through hole 107.

Example 4:

the left locking pin of the first clamping sheath is vertically opposite to the right locking pin of the second clamping sheath, and the left locking pin and the right locking pin of the second clamping sheath are oppositely arranged in the horizontal direction.

Example 5:

the inner walls of two sides of the clamping sheath are symmetrically provided with limiting pieces 9, and each side is at least provided with two limiting pieces which are arranged up and down.

Example 6:

as shown in fig. 4, during installation, the limiting sheet is clamped into the notch of the corrugated pipe to be limited, and the clamping sheath is wound along the outer side of the corrugated pipe. After the clamping sheath is wound, the left (right) locking pin is inserted into the left (right) locking hole, the front side of the locking pin is provided with a guide inclined plane for convenient positioning, and the front end of the locking pin is provided with an avoidance cylindrical cavity for ensuring that the locking pin has enough shrinkage allowance when being inserted into the locking hole. After the locking pin is locked in place, the guide body at the front end of the locking pin can be restored to the original shape to achieve the locking purpose.

Because left (right) locking pin, left (right) locking hole are relative from top to bottom in vertical direction, at the structure of horizontal direction side-to-side reversal, the slipknot structure has one end all the time to lock when receiving external force along cable axial direction to provide reaction force and make the slipknot of relative one side also can lock, thereby guarantee that the position of stop collar can not take place to remove, the spacing piece is for 2 upper and lower 4 increases spacing intensity of group. The locking structure is a movable buckle type, and is convenient to mount and dismount.

As shown in fig. 5, during disassembly, the locking pin can be pulled out only by applying an external force along the left (right) locking pin, the bottom angle of the guide body of the locking pin is in an R-angle transition, so that stress concentration can be reduced, and the locking pin is ensured to have enough strength to avoid damage when pulled out. After the locking pin is loosened, the clamping sheath is made of rubber materials, has elasticity, does not need to be manually pulled, and can be automatically loosened and reset. The distance body is consistent with the clamping sheath in material, and the shock absorption and buffering effects can be achieved when the plug collides with the cable to swing.

The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
