Examples

With reference to fig. 1 to 7, the present embodiment provides a quick-fit cable joint, including: body 100, locking piece 200, locking cover 300 and cable jacket 400. The body 100 is tubular, one end of the body is a mounting end, the other end is a fastening end, specifically, the mounting end is provided with at least one retaining portion 110, the locking element 200 is sleeved on the body 100 and can move along the axis of the body 100, and the body 100 is configured to be fixed to an external component 600 (e.g., an equipment housing) by the cooperation of the locking element 200 and the retaining portion 110. The locking cover 300 is movably sleeved at the fastening end; a plurality of elastic teeth 120 are uniformly distributed at the fastening end, and each elastic tooth 120 is enclosed to form an annular space; the cable jacket 400 is disposed in the annular space, and the cable jacket 400 is configured to press or release the elastic teeth 120 by the locking cover 300, thereby achieving switching between a clamping state and a releasing state.

Preferably, the cable jacket 400 is made of an elastic sealing material (e.g., silicone rubber, etc.), and when the cable jacket 400 is in the clamped state, one end of the cable jacket is abutted against the locking cover 300, and the other end of the cable jacket is abutted against the body 100, so that the cable jacket 400 and the body 100, and the cable jacket 400 and an external cable are all in a sealed state.

In this embodiment, the body 100 can be mounted and dismounted on the same side of the outer member 600. For example, an operator may insert the mounting end of the body 100 into the mounting hole of the outer member 600 from the front side or the outside of the outer member 600, so that the positioning portion 110 passes through the mounting hole and is engaged with the mounting hole, at this time, the locking member 200 and the positioning portion 110 are respectively located at the inner side and the outer side of the mounting hole, and the locking member 200 moves toward the positioning portion 110, thereby clamping the outer member 600 from the inner side and the outer side in cooperation with the positioning portion 110. During the dismantlement, with the locking piece 200 towards the direction removal of keeping away from button portion 110 to loosen outer part 600, and pull out button portion 110 from the mounting hole along the direction of keeping away from outer part 600, thereby realize this ready-package cable joint's homonymy dismouting, with the drawback that dismouting operation needs both sides to go on among the solution prior art, compare with prior art, the cable joint of homonymy dismouting, can improve the efficiency that the dismouting connects.

On the basis of the above embodiments, in an alternative embodiment of the present invention, the locking cover 300 and the locking piece 200 are both connected to the body 100 by screw threads. When the locking cover 300 is screwed in the direction close to the elastic teeth 120, the elastic teeth 120 are pressed tightly, and the corresponding cable jacket 400 is in a clamping state; alternatively, the locking cap 300 is unscrewed away from the elastic teeth 120, and the elastic teeth 120 are released, so that the corresponding cable jacket 400 is in a released state. The locking element 200 is rotated towards or away from the retainer 110 to correspondingly adjust the distance between the locking element 200 and the retainer 110 to clamp outer members 600 of different thicknesses.

Preferably, the locking cap 300 is connected by the first screw thread 130 of the body 100, and the locking element 200 is connected by the second screw thread 140 of the body 100; wherein, the first thread 130 and the second thread 140 have different rotation directions. For example, the first threads 130 are right-hand threads and the second threads 140 are left-hand threads. The threads with different rotation directions can prevent the locking cover 300 from loosening when the locking part 200 is rotated, or the locking part 200 from loosening when the locking cover 300 is rotated, which leads to the problem of incapability of screwing. And the thread direction is opposite, and when one of the two pieces is rotated, the other piece can be synchronously screwed.

Preferably, the locking element 200 is in the form of a nut. The locking piece 200 can be clamped by tools such as a wrench and the like to rotate, and the installation is convenient. In other embodiments, the locking element 200 may be other shapes, regular or irregular, such as triangular, quadrilateral, etc.

In another embodiment, an annular seal 500 is disposed between the locking element 200 and the capture portion 110. The annular sealing member 500 is preferably a sealing gasket which is sleeved on the body 100 and is pressed and sealed with the outer member 600 through the locking member 200 during assembly, so that external liquid (such as water) is prevented from entering the inner part of the equipment shell, and the use safety of the cable is improved.

On the basis of the above embodiment, in an optional embodiment of the present invention, the retaining portion 110 is protruded from the peripheral sidewall of the body 100, and the body 100 is provided with a notch 111 at least along a part of the periphery of the retaining portion 110, so that the retaining portion has elasticity at least partially, so as to facilitate the insertion of the mounting end into the assembling hole of the outer member 600.

Further, the buckling parts 110 are distributed along the axial center array of the body 100, wherein the buckling parts 110 are provided with guiding positions 112 and abutting positions 113; the guide bits 112 are gradually inclined in the assembling direction of the body 100; the abutment sites 113 are arranged horizontally for abutment against the outer member 600. When assembling, the retainer 110 is slid into the assembly hole of the outer member 600 along the guide direction 112, and when the locking element 200 is locked, the abutment 113 abuts against the outer member 600, thereby clamping the outer housing. In other embodiments, three, four, five, etc. buckling portions 110 may be provided, and preferably, in this embodiment, four buckling portions 110 are provided, so that on one hand, the stress on the mounting end is balanced and stable, and on the other hand, the mold structure of the molding body 100 can be simplified, so as to improve the production efficiency and reduce the product cost. It should be noted that the hole diameter of the mounting hole of the outer member 600 should be larger than the outer diameter of the mounting end and smaller than the outer circumference of the abutting portion 113 so that the retaining portion 110 can abut against the outer member 600.

In particular, the positioning portion 110 is further provided with a vertical position 114, which is connected with the abutting position 113 and the guiding position 112 in a stepped manner, and the outer circumference of the vertical position 114 is not greater than the outer circumference of the body 100. The locking device is suitable for the condition that the guiding position 112 is long, so as to prevent the problem that the buckling part 110 is bent or broken due to the fact that the guiding position 112 is outwards turned along the axial center of the body 100 when the locking element 200 is screwed and locked.

In another embodiment, the body 100 and the positioning portion 110 are integrally formed, so that the number of parts constituting the quick-assembly cable connector is reduced, the installation is more convenient, and the production cost is saved. Preferably, polyamide material is selected for injection molding, so that the body 100 has characteristics of temperature resistance, corrosion resistance and the like.

Above only the utility model discloses an it is preferred embodiment, the utility model discloses a scope of protection not only limits in above-mentioned embodiment, and the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
