Description

Technical Field

[0001] The invention belongs to the field of conductive connection devices in electrical components, and in particular relates to a cable connection structure. Background Art

[0002] In the field of smelting, the line from the transformer to the heating element is called a high current line, and flexible cables are often required in this line to compensate for equipment vibration or movement. Traditional cable installation methods are basically divided into horizontal and vertical methods. In the horizontal installation method, the cable has better force resistance, and the connection method often adopts a ferrule structure. In the vertical installation method, due to the cable's own gravity and equipment movement, the connection point is subjected to greater force, and a flange connection method is often used.

[0003] Traditional cable installation methods have the following main disadvantages:

[0004] (1) The use occasions are single. For occasions that require both horizontal installation and vertical installation, it is necessary to prepare both the ferrule structure and the flange connection structure, resulting in a wide variety of cable connectors and high management costs for manufacturers.

[0005] (2) The water seal positioning effect is poor and the probability of water leakage is high.

[0006] (3) The flange connection structure is bulky and occupies a large space. Summary of the invention

[0007] In view of this, the purpose of the present invention is to provide a cable connection structure, which can realize the cable being firmly connected to the conductive copper tube in a horizontal or vertical state with only one connection method, thereby facilitating cable interchange and organizing production, and reducing the types and management costs of spare parts for manufacturers.

[0008] In order to achieve the above object, the present invention provides the following technical solutions:

[0009] A cable connection structure comprises a conductive copper tube, a cone sleeve, an inner cone cap and an inner cone connector; a force-bearing groove is provided on the outer peripheral surface of one end of the conductive copper tube around the circumference of the copper tube.

[0010] The cone sleeve has two outer cone surfaces, and the two end heads of the cone sleeve correspond to the upper bottom circle of the truncated cone where the two outer cone surfaces are located. A force-bearing clamping ring is provided on the inner wall surface of the cone sleeve. The cone sleeve is sleeved on the conductive copper tube and its force-bearing clamping ring is correspondingly embedded in the force-bearing clamping groove of the conductive copper tube.

[0011] One end of the inner cone cap has an inner cone hole, which is sleeved on the conductive copper tube and its inner cone hole corresponds to the outer cone surface of the cone sleeve away from the end of the conductive copper tube, and the other end of the inner cone cap corresponds to the outer periphery of the other outer cone surface of the cone sleeve.

[0012] One end of the inner cone connector also has an inner cone hole, and the end of the conductive copper tube with a cone sleeve extends into the inner cone connector. The inner cone connector and the other end of the inner cone cap are detachably connected, and the inner cone hole of the inner cone connector corresponds to the other outer cone surface on the cone sleeve.

[0013] Furthermore, along the axial direction, through grooves are opened on the cone sleeve and penetrate to both ends of the cone sleeve, so that the cone sleeve forms an open ring structure.

[0014] Furthermore, the cone sleeve is divided into two independent parts, an upper sleeve and a lower sleeve, and both the upper sleeve and the lower sleeve are C-shaped structures.

[0015] Furthermore, along the axial direction, a plurality of opening grooves are arranged facing each other from both ends of the cone sleeve to the middle of the cone sleeve, and the opening grooves arranged facing each other do not penetrate each other.

[0016] Furthermore, the force-bearing clamping ring is located in the middle of the cone sleeve, and the opening grooves arranged opposite to each other are arranged on both sides of the force-bearing clamping ring.

[0017] Furthermore, the opening groove is a U-shaped groove.

[0018] Furthermore, the end of the inner cone cap that matches the inner cone connector is internally provided with threads, and the outer circumference is a polygonal column structure.

[0019] Furthermore, an outer peripheral surface of the end of the inner cone connector having the inner cone hole is provided with an external thread.

[0020] Furthermore, a plurality of sealing ring grooves are provided on the inner cone connector at the rear of the inner cone hole.

[0021] The beneficial effects of the present invention are:

[0022] This connection structure can be installed horizontally or vertically. The force-bearing clamp ring on the cone sleeve is tightly buckled in the force-bearing clamp groove of the conductive copper tube. When installed vertically, the cable connector transfers the force to the force-bearing clamp groove through the force-bearing clamp ring and acts on the conductive copper tube. It has good force, reliable connection, convenient assembly and disassembly, simple and compact structure, and wide application occasions. The adoption of this structure ensures the reliability of water-tight positioning and reduces the probability of water leakage. It reduces the types of cable connectors, facilitates production organization, and reduces the types and management costs of spare parts of manufacturers.

The objectives and other advantages of the present invention can be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] See also Figure 1 to Figure 6 , is a cable connection structure, including a conductive copper tube 1, a cone sleeve 2, an inner cone cap 3 and an inner cone connector 4; a force-bearing groove 101 is provided on the outer circumferential surface of one end of the conductive copper tube 1 around the circumference of the copper tube; the cone sleeve 2 has two outer cone surfaces, namely, outer cone surface Ⅰ201 and outer cone surface Ⅱ202, and the two end faces of the cone sleeve 2 correspond to the upper bottom circle of the truncated cone where the two outer cone surfaces are located (that is, the bottom circle with a smaller diameter on the truncated cone), and a force-bearing clamping ring 203 is provided on the inner wall surface of the cone sleeve 2, and the cone sleeve 2 is sleeved on the conductive copper tube 1 and its force-bearing clamping ring 203 is correspondingly embedded in the force-bearing groove 101 of the conductive copper tube 1. One end of the inner cone cap 3 has an inner cone hole 301, and the inner cone cap 3 is mounted on the conductive copper tube 1 and its inner cone hole 301 corresponds to the outer cone surface Ⅰ201 on the cone sleeve 2 away from the end of the conductive copper tube, and the other end of the inner cone cap 3 (also the end connected to the inner cone connector 4) is corresponding to the outer periphery of the outer cone surface Ⅱ202 on the cone sleeve; one end of the inner cone connector 4 also has an inner cone hole 401, and the end of the conductive copper tube 1 on which the cone sleeve 2 is mounted extends into the inner cone connector 4, and the inner cone connector 4 and the connecting end of the inner cone cap 3 are detachably connected and the inner cone hole 401 of the inner cone connector 4 corresponds to the outer cone surface Ⅱ202 on the cone sleeve 2.

[0037] In this connection structure, the cone sleeve 2 is sleeved on the outer surface of the conductive copper tube 1, and the force-bearing clamping ring 203 is clamped into the force-bearing clamping groove 101. One end of the conductive copper tube 1 is sleeved into the inner cone cap 3, and the other end is inserted into the inner cone connector 4. The inner cone cap 3 is a hollow structure, and the inner cone connector 4 is also a hollow structure. The inner cone cap 3 has a thread 302 inside the end that matches the inner cone connector 4, and correspondingly, the outer peripheral surface of the end with an inner cone hole 401 on the inner cone connector 4 is provided with an external thread 402. The inner cone cap 3 and the inner cone connector 4 are connected correspondingly through threads. When tightened, the inner cone cap 3 and the inner cone connector 4 internal cone surface correspondingly press the outer cone surface Ⅰ201 and the outer cone surface Ⅱ202 on the cone sleeve 2, so that the cone sleeve 2 hugs the conductive copper tube 1, and the force-bearing clamping ring 203 and the force-bearing clamping groove 101 are firmly connected. Preferably, the outer periphery of the end of the inner cone cap 3 that matches the inner cone connector 4 is set to be polygonal, so that the inner cone cap 3 of this section forms a columnar structure, which is convenient for turning the inner cone cap.

[0038] The connection structure is flexible in disassembly and installation, and has a firm and reliable connection. It can be applied to various installation forms such as horizontal and vertical, and is convenient for cable interchange and production organization.

[0039] The specific form of the cone sleeve 2 is: along the axial direction, the cone sleeve 2 is provided with through grooves 204 that penetrate to both ends of the cone sleeve 2. The through grooves 204 can form an open ring structure for the cone sleeve, and the cone sleeve 2 can be installed and clamped correspondingly by expanding and contracting the mouth.

[0040] There is another variation of the cone sleeve 2, that is, the cone sleeve 2 is divided into two independent parts, an upper sleeve 205 and a lower sleeve 206, wherein both the upper sleeve 205 and the lower sleeve 206 are C-shaped structures. This structure is equivalent to having two through grooves to equally cut the cone sleeve 2 into two parts, and the upper sleeve 205 and the lower sleeve 206 are clamped on the outer surface of the conductive copper tube 1, and the force-bearing clamping ring 203 is clamped into the force-bearing clamping groove 101. This structural form is more convenient for installation and is a preferred embodiment.

[0041] In this solution, the cone sleeve 2 is a truncated cone-shaped hollow structure, which is evenly divided into two parts. Along the axial direction, each part is provided with a plurality of opening grooves 207 from both ends of the cone sleeve 2 to the middle of the cone sleeve 2. The opening grooves here are U-shaped grooves. The opening grooves 207 arranged opposite to each other do not intersect each other. The force-bearing clamping ring 203 is located in the middle of the cone sleeve 2, and the opening grooves 207 arranged opposite to each other are arranged on both sides of the force-bearing clamping ring 203. The opening grooves 207 facilitate holding the conductive copper tube 1 tightly after being stressed.

[0042] Preferably, the inner cone connector 4 is provided with a plurality of sealing ring grooves 403 behind the inner cone hole 401. The sealing ring grooves 403 can be embedded with sealing rings to achieve sealing between the conductive copper tube 1 and the inner cone connector 4.

[0043] The connection structure can be installed horizontally or vertically. The force-bearing clamp ring 203 on the cone sleeve 2 is tightly buckled in the force-bearing clamp groove 101 of the conductive copper tube 1. When installed vertically, the cable connector transfers the force to the force-bearing clamp groove through the force-bearing clamp ring 203 and acts on the conductive copper tube. The force-bearing structure is good, the connection is reliable, the structure is simple and compact, and the application occasions are wide. The use of this structure ensures the reliability of water-tight positioning and reduces the probability of water leakage. It also reduces the types of cable connectors, which is convenient for organizing production.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
