Description

Technical Field

[0001] The invention belongs to the technical field of connectors, and in particular relates to a combined wire clamping accessory and a connector. Background Art

[0002] The existing wire clamp accessories have the following processing methods:

[0003] (1) Figure 1 As shown, the wire clip is directly riveted to the connector housing, but this assembly method has the disadvantages of having many parts, high assembly cost, and difficult to control riveting quality.

[0004] (2) The wire clamp is directly machined on the connector housing through machining, but this method is suitable for housings machined by turning and milling, but not for thin-walled parts machined by stamping.

[0005] Therefore, there is a need for a wire clamping structure that is easy to process and assemble, has low requirements on the structure of the parts themselves, and can adapt to the use needs of parts of different thicknesses. Summary of the invention

[0006] The invention provides a combined wire clamping accessory, which enables the wire clamp to be assembled quickly and reliably through the cooperation of a locking ear on the wire clamp and a locking hole at the rear of an accessory housing.

[0007] The purpose of the present invention and the technical problem to be solved are achieved by adopting the following technical solutions. According to a combined wire clamp accessory proposed by the present invention, it includes an accessory housing 1 and at least two wire clamps, the wire clamp includes an arc-shaped limiting portion 7, a plate-shaped connecting portion 8 located at both ends of the limiting portion, and a locking ear 10 connected to the bottom of one of the connecting plates 8 through a cantilever 9, and the rear of the accessory housing 1 is provided with at least two locking holes with rectangular cross-sections distributed around the wire outlet hole, and the locking ear 10 can enter the corresponding locking hole when the wire clamp is tilted, and is stopped and limited by the inner wall of the locking hole when the wire clamp is straightened.

[0008] The purpose of the present invention and the solution to its technical problems can be further achieved by adopting the following technical measures.

[0009] The aforementioned combined wire clamp accessory has two wire clamps, which are respectively engaged with the first locking hole 5 and the second locking hole 6 distributed on both sides of the wire outlet hole through the locking ears 10, and the cross-sections of the limiting parts of the two wire clamps are semicircular.

[0010] In the aforementioned combined wire clamping accessory, the first locking hole 5 and the second locking hole 6 are staggeredly distributed on both sides of the wire outlet hole, so that the limiting parts 7 of the two wire clamps are arranged opposite to each other to form an arc structure for limiting the outer circumference of the cable.

[0011] In the aforementioned combined wire clamp accessory, the first locking hole 5 and the second locking hole 6 are point-symmetrically distributed on both sides of the accessory shell with the center of the wire outlet hole as the symmetry center, and the adjacent edges of the two are located on the same straight line passing through the symmetry center, so that when the assembly is completed, there is a very small gap between the connecting parts of the two wire clamps.

[0012] In the aforementioned combined wire clamp accessory, the connecting portion 8 is connected and locked with the connecting portion 8 of another wire clamp through a locking piece thereon. When the connecting portion 8 is locked by the locking piece, the limiting portion realizes a sheathing clamping of the cable sheath.

[0013] The aforementioned combined wire clamp accessory, the locking part includes a locking screw 4 and a nut, and the connecting part 8 is provided with a locking hole 11 for the locking screw 4 to pass through, so that after the wire clamp is assembled, the relatively arranged connecting parts 8 can be connected together by the locking screw 4 and the nut, so that the limiting part 7 can clamp the outer periphery of the cable.

[0014] The aforementioned combined wire clamping accessory, the locking ear 10 is located at the end of the cantilever 9 and both ends protrude from the cantilever 9, the rear end surface of the protruding part is used to stop and limit with the inner wall of the locking hole on the accessory shell, and the length and thickness of the cantilever 9 are slightly smaller than the locking hole, which can realize the small size floating of the locking ear in the locking hole, and also ensure the reliable positioning of the locking ear in all directions.

[0015] The aforementioned combined wire clamp accessory has a guiding structure on one side of the front end of the locking ear 10 close to the limiting portion 7, and the guiding structure can reduce the projection length of the locking ear 10 in the locking hole and guide the locking ear 10 into the locking hole when the wire clamp is in an inclined state with the connecting plate with the locking ear 10 arranged at the bottom.

[0016] In the aforementioned combined wire clamp accessory, the guide structure is chamfered or rounded, and the setting of the chamfered or rounded corners reduces the difficulty of the locking ear 10 entering the locking hole in an inclined state, thereby achieving rapid and reliable assembly of the wire clamp.

[0017] The aforementioned combined wire clamp accessory has an arc-shaped guide structure, and has an arc-shaped guide structure extending from the front end surface to the rear end surface on the side of the locking ear 10 facing the limiting portion 7. This can reduce the projection size of the locking ear at the locking hole in an inclined state while ensuring the size of the stop surface at the rear fixed end of the locking ear and the inner wall of the locking hole. This can reduce the difficulty of the locking ear 10 entering the locking hole in an inclined state, thereby achieving rapid and reliable assembly of the wire clamp.

[0018] Compared with the prior art, the present invention has obvious advantages and beneficial effects. By means of the above technical solution, the present invention can achieve considerable technical advancement and practicality, and has wide industrial utilization value, and has at least the following advantages:

[0019] The present invention innovatively designs a rectangular locking hole on the accessory shell and a locking ear structure on the wire clamp. The length of the locking ear is longer than the length of the rectangular locking hole. The locking ear can be inserted into the rectangular hole of the accessory shell in an inclined state and can be stuck. In this way, after the left and right wire clamp locking ears are installed in the rectangular locking holes of the accessory shell, the wire clamp can be fixed left and right and up and down.

[0020] The combined wire clamping accessory of the present invention has the characteristics of simple structure and convenient assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation method, structure, characteristics and effects of the combined wire clamping accessory proposed by the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0045] See also Figure 1-8 , which is a schematic diagram of the structure of each part of the combined wire clamping accessory of an embodiment of the present invention, the combined wire clamping accessory includes an accessory shell 1 and a first wire clamp 2 and a second wire clamp 3 arranged at the rear of the accessory shell 1, wherein the first wire clamp 2 and the second wire clamp 3 are respectively engaged with the first locking hole 5 and the second locking hole 6 on the rear end surface of the accessory shell 1 through the locking ears 10 thereon, thereby realizing assembly and fixation at the rear of the accessory shell 1.

[0046] The first wire clamp 2 and the second wire clamp 3 both include an arc-shaped limiting portion 7 and a plate-shaped connecting portion 8 located at both ends of the arc-shaped limiting portion 7, wherein the arc-shaped limiting portion 7 is used to radially limit the outer circumference of the cable, and a locking piece is provided on the plate-shaped connecting portion 8 for connecting and locking with the connecting portion of another wire clamp, thereby realizing the connection and locking of the relatively arranged first wire clamp 2 and second wire clamp 3, so that the first wire clamp 2 and second wire clamp 3 can realize radial surrounding limiting of the outer circumference of the cable.

[0047] In this embodiment, the locking member is a locking screw 4 and a nut, and the connection part is provided with a locking hole 11 for the locking screw 4 to pass through. When the cable needs to be limited, the locking screw 4 is sequentially passed through the locking hole 11 on the connection part on one side of the first wire clamp 2 and the second wire clamp 3 and the locking screw 4 is locked by the nut, so that the connection parts of the first wire clamp 2 and the second wire clamp 3 on this side are close to each other; then another locking screw is passed through the locking hole on the connection part on the other side of the first wire clamp 2 and the second wire clamp 3, and the locking screw is locked by the nut. By adjusting the position of the nuts on the two locking screws, the relatively arranged connection parts of the first wire clamp 2 and the second wire clamp 3 are close to each other, and then the limiting parts on them are close to each other to press the cable sheath.

[0048] In other embodiments of the present invention, the locking member may also be a locking rope or other structures capable of connecting the interconnected wire clamp connecting parts together.

[0049] In this embodiment, the first locking hole 5 and the second locking hole 6 are staggered and distributed on both sides of the outlet hole at the rear of the accessory housing, and both are rectangular holes. In this embodiment, the first locking hole 5 and the second locking hole 6 are point-symmetrically distributed on both sides of the accessory housing with the center of the outlet hole of the accessory housing as the symmetry center, so that the first wire clamp 2 adapted and locked with the first locking hole 5 through the locking ear and the second wire clamp 3 adapted and locked with the second locking hole 6 through the locking ear are relatively distributed on the accessory housing. Preferably, the opposite sides of the first locking hole 5 and the second locking hole 6 are located on the same straight line passing through the symmetry center.

[0050] The locking ears 10 of the first wire clamp 2 and the second wire clamp 3 are both located below one of the connecting parts 8, and the locking ears 10 are connected and fixed to the connecting part 8 through a cantilever 9 formed by extending downward from the bottom of the connecting part 8. The locking ears 10 are located at the end of the cantilever 9, and the length of the locking ears 10 (along the distribution direction of the two locking holes) is greater than the length of the locking hole adapted thereto, and the thickness is less than the width of the locking hole adapted thereto. The length (along the distribution direction of the two locking holes) and the width of the cantilever 9 are both less than the length and width of the locking hole, so that when the wire clamp is deflected, the locking ears 10 can enter the corresponding locking holes on the accessory housing 1 in an inclined state, and when the wire clamp is turned straight, the locking ears 10 can be stopped and limited by the locking holes, so that they cannot escape from the locking holes, thereby realizing a reliable connection between the wire clamp and the accessory housing.

[0051] Since the length of the locking ear 10 is relatively long, both ends thereof protrude the cantilever 9, and the end surface of the rear end of the protruding part is perpendicular to the cantilever 9, and can be stopped and limited by the inner wall of the locking hole on the accessory housing. The end (left end) of the locking ear 10 protruding from the cantilever 9 and close to the limiting portion 7 is defined as the first end, and the end (right end) away from the limiting portion is defined as the second end. When the locking ear 10 is installed in the locking hole, the locking ear 10 is in an inclined state with the first end on top and the second end on the bottom. Preferably, in order to enable the locking ear 10 to be smoothly installed in a locking hole of smaller size in an inclined state and reduce the size of the opening at the rear of the accessory housing, a guide structure 12 is provided on one side (the front end edge of the first end) of the front end of the locking ear 10 of the present invention close to the limiting portion 7. The guide structure 12 can reduce the projection length of the locking ear 10 in the locking hole in the inclined state, and can guide the locking ear 10 into the corresponding locking hole when the wire clamp is in an inclined state with the connecting portion without the locking ear 10 on top. Preferably, the guide structure 12 is chamfered or rounded. In this embodiment, the surface of the locking ear 10 facing the other connecting portion is an arc surface, but it is not limited to this. The corner of the rear end of the locking ear close to the limiting portion is also rounded or chamfered. That is, the locking ear 10 of the present invention has an arc-shaped guide structure 12 extending from the front end surface 13 to the rear end surface 14 on the side facing the limiting portion 7. The arc-shaped guide structure 12 effectively reduces the projection length of the locking ear in the direction of the locking hole in the inclined state, thereby enabling the fast assembly of the locking ear.

[0052] In this embodiment, the first wire clamp 2 and the second wire clamp 3 have exactly the same structure and are integrally formed, and the first locking hole 5 and the second locking hole 6 have the same size.

[0053] In other embodiments of the present invention, a plurality of locking holes are evenly distributed around the wire outlet hole at the tail of the accessory housing 1, and each locking hole is connected to a tail clip through a locking ear. When adjacent tail clips are connected and locked through the connecting part, the above-mentioned tail clips jointly realize radial limitation of the outer circumference of the cable.

[0054] The present invention further provides a connector having the above-mentioned combined wire clamping accessory, wherein the housing of the connector is integrated with the accessory housing 1 of the above-mentioned combined wire clamping accessory or connected to the accessory housing 1 through a connecting piece.

[0055] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with the profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
