Description

Technical Field

[0001] The utility model relates to the technical field of cable couplings, in particular to a spring-clip type cable penetration coupling. Background Art

[0002] The cable crossing coupling is a tool used in the middle of the downhole oil pipe connection. Its function is to connect the front and rear oil pipes and fix and protect the accompanying cable.

[0003] The structure of the existing cable crossing coupling is to open a groove on the outside of the tool, and the cable is inserted into the groove to achieve a fixing effect when in use. The other is a C-ring type fixation, in which a straight groove is opened on the coupling body. After the cable crossing coupling is connected to the oil pipe, the cable is placed in the coupling groove. After the C-ring fixes the cable, the C-ring is fastened to the coupling with screws. First, there are problems such as long processing cycle, complex internal structure of the groove, and high cost. Second, there is the problem of using screws to fasten the C-ring, and there is a problem of the screw falling off during use. Once the screw falls off, the entire oil pipe may be scrapped, which poses a great safety hazard and cost problem. Utility Model Content

[0004] To this end, an embodiment of the utility model provides a spring-type cable crossing coupling to solve the problems of potential safety hazards and high costs in the prior art due to the complex and unstable structure of the fixed cable.

[0005] In order to achieve the above-mentioned purpose, the embodiment of the utility model provides the following technical solutions: a spring-type cable crossing coupling, comprising a coupling body for connecting an oil pipe, wherein a positioning assembly for fixing a cable is provided outside the coupling body;

[0006] The positioning assembly includes three embedding grooves, which are all arranged outside the coupling body, and the top and bottom ends of the embedding grooves are each provided with a through hole communicating with the coupling body, and the through hole is connected with the embedding groove;

[0007] The top and bottom ends of the three embedding grooves are sleeved with retaining springs, which are sleeved on the outside of the coupling body. A connecting hole is opened on one side of the coupling body close to the retaining spring, and the connecting hole is connected with the through hole and the embedding groove.

[0008] Furthermore, hook feet are installed on the sides of the two ends of the retaining spring that are close to each other, the two hook feet are arranged inside the same through hole, and the sides of the two hook feet that are far away from each other are in contact with the inner wall of the through hole. Through the snap connection between the hook feet and the through hole, the retaining spring can be fixed and limited to prevent the retaining spring from rotating, thereby ensuring the stability of the retaining spring when fixing the cable.

[0009] Furthermore, the thickness of the retaining spring is smaller than the depth of the connecting hole. By setting the thickness of the retaining spring to be smaller than the depth of the connecting hole, the outermost part of the retaining spring will not contact the outside, thereby preventing the retaining spring from being damaged by external equipment.

[0010] Furthermore, the three embedding grooves are evenly distributed in a circular array with the center of the coupling body as the center. The provision of the three embedding grooves can facilitate multi-faceted installation according to cable layout requirements, thereby improving the flexibility of the workers in installing the cables.

[0011] The utility model embodiment has the following advantages:

[0012] Through the tightening effect of the retaining spring, the cable installed in the embedded groove can be fixed and limited, and then the retaining spring can be fixed with the help of the engagement connection between the hook foot and the through hole, avoiding the retaining spring from rotating and the cable from being misplaced and separated, thereby ensuring the stability of the retaining spring when fixing the cable, thereby achieving the effects of simple structure, low cost and convenient operation, thereby improving installation efficiency, shortening processing cycle and reducing use cost.

People familiar with the technology can easily understand other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Refer to the instruction manual Figure 1-3 The utility model provides a spring-clip cable crossing coupling, comprising a coupling body 1 for connecting an oil pipe, wherein a positioning assembly for fixing a cable is arranged outside the coupling body 1;

[0021] like Figure 1-3 As shown, the positioning assembly includes three embedding grooves 2, which are all opened on the outside of the coupling body 1, and the top and bottom ends of the embedding grooves 2 are each provided with a through hole 3 connected to the coupling body 1, and the through hole 3 is connected to the embedding groove 2; the top and bottom ends of the three embedding grooves 2 are each sleeved with a retaining spring 4, and the retaining spring 4 is sleeved on the outside of the coupling body 1, and a connecting hole 5 is opened on the side of the coupling body 1 close to the retaining spring 4, and the connecting hole 5 is connected to the through hole 3 and the embedding groove 2.

[0022] Hook feet 6 are installed on the sides of the two ends of the clamping spring 4 that are close to each other. The two hook feet 6 are arranged inside the same through hole 3, and the sides of the two hook feet 6 that are far away from each other are in contact with the inner wall of the through hole 3. Through the snap connection between the hook feet 6 and the through hole 3, the clamping spring 4 can be fixed and limited to prevent the clamping spring 4 from rotating, thereby ensuring the stability of the clamping spring 4 when fixing the cable.

[0023] like Figure 2 As shown, the thickness of the retaining spring 4 is smaller than the depth of the connecting hole 5. By setting the thickness of the retaining spring 4 to be smaller than the depth of the connecting hole 5, the outermost part of the retaining spring 4 will not contact the outside, thereby preventing the retaining spring 4 from being damaged by external equipment.

[0024] like Figure 1-3 As shown, the three embedding grooves 2 are evenly distributed in a circular array with the center of the coupling body 1 as the center. The arrangement of the three embedding grooves 2 can facilitate multi-faceted installation according to cable layout requirements, thereby improving the flexibility of the workers in installing the cables.

[0025] The provision of three embedded grooves 2 can facilitate the staff to perform multi-faceted installation according to the cable layout requirements, thereby improving the flexibility of the staff in installing the cable, and the staff can smoothly insert the cable into the embedded groove 2 without bending the cable too much, thereby improving the convenience of the staff in installing the cable;

[0026] Afterwards, the retaining spring 4 is nested in the connecting hole 5 outside the coupling body 1, so that the retaining spring 4 can limit and fix the cable placed in the embedding groove 2 to avoid the cable from being separated from the embedding groove 2. The retaining spring 4 can enhance the connection stability and tightness between the retaining spring 4 and the coupling body 1 by means of the engagement of the two hook feet 6 with the through hole 3, prevent the retaining spring 4 from rotating during use, and ensure the stability of the retaining spring 4 in fixing the cable. The overall structure is simple, the cost is low, and the operation is convenient, which can effectively improve the installation efficiency, thereby effectively shortening the processing cycle and reducing the cost of use.

[0027] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
