Abstract
The utility model relates to a tensile-resistant anti-looseness connector which comprises a connector housing, wherein, at least two groups of conical surface wire pressing structures for clamping a cable force-bearing part are arranged in a taper hole section in a cable channel of the connector housing which is near to a cable inlet end, each conical surface wire pressing structure is formed by matching an internal inserting sleeve and an external inserting sleeve of coaxial taper sleeves, the opposite surfaces of the internal and the external adjacent taper sleeves are matched with each through conical surfaces which are in the same taper direction, and a pushing part for providing the axial pushing force for the taper sleeve is arranged at the large-diameter end of each taper sleeve. The tensile-resistant anti-looseness connector has compact structure, can save raw materials, save cost, and facilitate transportation and use.
Description
Technical field
The utility model relates to a kind of stretching resistance anti-loose connector.
Background technology
At present, adopt afterbody that one taper hole is set mostly in the stretching resistance field of connectors at connector, corresponding inserted one tapered sleeve in the taper hole, be used to press from both sides the load spare of establishing cable between the conical surface of taper hole and tapered sleeve corresponding matching, the bigger diameter end of tapered sleeve is provided with a swivel nut with the connector shell bolt, can provide a corresponding axial pressing force for tapered sleeve by screwing swivel nut.Adopt this mode simple in structure, the load spare of cable compresses between the conical surface that cooperatively interacts reliably, has played good anti-loose effect.But, still there is weak point in this kind mode, because the length of the pulling force that this kind connector is resisted and the taper hole that cooperatively interacts and tapered sleeve has corresponding relation, promptly the length that cooperatively interacts of taper hole and tapered sleeve is long more, the pulling force that connector is resisted is big more, and anti-loose ability is strong more.When satisfying cable incoming line size, prolong the length that cooperates the conical surface, then the external diameter of connector shell and tapered sleeve also increases accordingly, and the external diameter increase of connector shell and tapered sleeve bigger diameter end directly causes the connector volume to increase, and quality increases.This certainly will increase production cost, also is unfavorable for transportation and use simultaneously.
The utility model content
The purpose of this utility model provides a kind of compact conformation, and production cost is low, is convenient to the stretching resistance anti-loose connector that transports and use.
For achieving the above object, the utility model adopts following technical scheme: a kind of stretching resistance anti-loose connector, comprise connector shell, be provided with at least two groups in the taper hole section in the cable passage of the close cable lead-in wire terminal of described connector shell and be used to press from both sides the conical surface pressuring line structure of establishing cable load spare, described conical surface pressuring line structure is to be cooperated by sleeve inside and outside the coaxial tapered sleeve to constitute, the opposite face of inside and outside two adjacent tapered sleeves is with the identical cone match of taper direction, and the bigger diameter end of each tapered sleeve is provided with the part that holds out against that axial pressure is provided for tapered sleeve.
The taper direction of described every group of conical surface pressuring line structure is identical.
The cone angle scope of described every group of conical surface pressuring line structure is 4 °～12 °.
The stretching resistance anti-loose connector of such scheme is provided with two groups or more and is used to press from both sides the cone structure that cooperatively interacts of establishing cable load spare, like this can be under the situation that does not increase connector length, the conical surface length that has extended and cooperatively interacted is taken off pulling force for connector provides enough big loosening.Stretching resistance anti-loose connector compact conformation of the present utility model saves material, and saves cost and is convenient to transportation and use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Stretching resistance anti-loose connector of the present utility model shown in Figure 1, comprise connector shell 3, be provided with the cable passage in the connector shell 3, the stage casing of cable passage is provided with first taper hole, cable passage near the first taper hole bigger diameter end is a screwed hole, tapered sleeve 5 of corresponding plug-in mounting in first taper hole is spirally connected in the screwed hole one and holds out against swivel nut 2, holds out against between swivel nut 2 and tapered sleeve 5 opposing end faces and is folded with a packing ring 4.Be provided with one in the tapered sleeve 5 along its axially extended second taper hole, second taper hole is identical with the taper direction of first taper hole, and the cone angle scope of first taper hole and second taper hole is 4 °～12 °, correspondence is fitted with cone 6 in second taper hole, the endoporus that holds out against swivel nut 2 is a screwed hole, be bolted with one in this screwed hole and hold out against part 1, hold out against part 1 and press closer on the end face with cone 6.
Stretching resistance anti-loose connector of the present utility model in use, at first the cable inlet of cable 8 from connector shell 3 penetrated in the connector shell 3, the back segment of the load spare 7 of the cable of the cable sheath that will exhume out then is folded between the conical surface that first taper hole and tapered sleeve 5 cooperatively interact, again folding behind the leading portion of load spare 7 is folded in afterwards between the conical surface that second taper hole and cone 6 cooperatively interact, screw respectively more at last and hold out against swivel nut 2 and hold out against part 1, the load spare 7 of cable 8 is among the roof pressure of bipyramid face, has guaranteed the anti-loose reliability of connector stretching resistance.The utility model is not limited only to two groups of conical surfaces folders that cooperatively interact and establishes conical surface folder that load spare cooperatively interacts more than 7, two groups and establish load spare 7 and also belong to protection range of the present utility model.
Claims (3)
