Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a connection mechanism for cables with braided layers. Background Technology

[0002] With the rapid development of the semiconductor industry, the actual power used in chip manufacturing, chip testing, and chip packaging is increasing. The demand for high-power radio frequency transmission cables is growing daily. Conventional high-power cable wiring methods include... Figure 1 As shown, the cable's braided layer is primarily compressed using the clamps and the beveled surface of the main body. Then, the cable sheath is secured by an O-ring at the tail end, or the clamps hold the cable at a single point, thus fixing the overall position of the cable.

[0003] However, this conventional wiring method causes the braided layer to become tangled, resulting in metal wires inserting into the cavity during wiring. Furthermore, as the cable braid is screwed into the main body, the tangled braid will unravel due to friction and concentrate in one place, generating tensile force and thus damaging the braid. All of these factors affect the voltage withstand capability, requiring personnel to repeatedly confirm the installation. Utility Model Content

[0004] This invention provides a connection mechanism for cables with braided layers, which can protect the overall structure and performance of the cable and ensure the holding force of the connection mechanism on the cable.

[0005] To solve the above-mentioned technical problems, the present invention provides a connection mechanism for cables with braided layers, comprising: a wire clamp and a screw sleeve. The wire clamp has a first mounting hole axially, one end of the cable is disposed in the first mounting hole, and a fixing ring extends from the end of the wire clamp near the main body. A fixing groove is provided on the outer side of the fixing ring. The braided layer of the cable is folded around the end face of the fixing ring and covers the fixing groove. A retaining ring is provided on the fixing groove, and the retaining ring fixes the braided layer covering the fixing groove to the fixing ring.

[0006] The screw sleeve is fitted onto the tail of the wire clamp so that the tail of the wire clamp is clamped onto the surface of the outer sheath of the cable.

[0007] Preferably, the fixing ring includes a lower limit part, a side pressing part, and an upper fixing part. The lower limit part is located on the outer side of the braided layer, the side pressing part is located at the end face of the fixing ring, and the upper fixing part is located on the outer side of the fixing ring. A fixing groove is formed on the upper fixing part. The side pressing part cooperates with the main body to axially compress and fix the braided layer. The lower limit part is used to limit the movement space of the braided layer, and the upper fixing part is used to support and contact the folded braided layer.

[0008] Preferably, the side pressing part is vertically arranged, and the inner cavity of the main body has a vertically arranged platform surface that cooperates with the side pressing part. The folded part of the woven layer is located between the side pressing part and the platform surface of the main body, and the side pressing part and the platform surface are mutually squeezed.

[0009] Preferably, a first transition portion is provided between the lower limit portion and the side pressure portion, and a second transition portion is provided between the side pressure portion and the upper fixing portion.

[0010] Preferably, the diameter at the lower limit is smaller than the diameter of the first mounting hole, so that a blocking part is formed between the side of the lower limit and the first mounting hole. The blocking part matches the cross section of the outer sheath of the cable to limit the outer sheath and does not affect the passage of the braided layer.

[0011] Preferably, the tail of the clamp includes multiple clamping plates for clamping the cable, with a deformation gap between adjacent clamping plates, and a clamping tooth assembly extending from the side of the clamping plate near the first mounting hole. The screw sleeve and the clamping plate are pressed together to make the multiple clamping plates move toward the cable in the first mounting hole, while the clamping tooth assembly presses against the outer sheath of the cable.

[0012] Preferably, the threaded sleeve has a second mounting hole that allows the cable to pass through. The threaded sleeve is fitted onto the wire clamp through the second mounting hole. The tail of the second mounting hole gradually narrows to form a conical cavity. When the threaded sleeve is assembled, the conical cavity and the clamping plate are pressed together so that the ends of the multiple clamping plates close to the conical cavity are pulled together and pressed onto the outer sheath by the clamping teeth.

[0013] Preferably, the clamping tooth assembly includes a first clamping tooth, a second clamping tooth, and a third clamping tooth arranged in sequence. The third clamping tooth is arranged at the tail of the clamping clamp plate. When the clamping tooth assembly does not press on the cable, the distance between the first clamping tooth, the second clamping tooth, the third clamping tooth and the outer sheath of the cable gradually increases.

[0014] Preferably, the outer edge of the clamp is provided with external threads, and the threaded sleeve and the main body are provided with internal threads.

[0015] The beneficial effects of this utility model are as follows: the braided layer of the cable is folded and wrapped around the fixing ring, so that the braided layer is evenly distributed on the outer surface of the fixing ring and is fixed to the fixing ring by the retaining ring, so that the braided layer cannot be displaced, thereby fixing the position of the cable; at the same time, the folded braided layer is axially squeezed between the fixing ring and the main body, thereby further fixing the position and making full contact with the main body; furthermore, the surface of the outer sheath of the cable is clamped by the screw sleeve, thereby further fixing the position of the cable.

[0035] Example:

[0036] like Figure 2 As shown, the cable includes a conductor 11, an insulation layer 12 wrapped around the conductor 11, a braided layer 13 covering the insulation layer 12, and an outer sheath 14 wrapping the braided layer 13.

[0037] refer to Figures 2-5 A connection mechanism for a braided cable includes a clamp 2 and a screw sleeve 3. The clamp 2 has a first mounting hole 21 axially, into which one end of the cable can be inserted. The clamp 2 has a fixing ring 4 coaxial with the first mounting hole 21 at one end near the main body 6. A fixing groove 46 is formed on the outer surface of the fixing ring 4. The braided layer 13 of the cable is folded around the end face of the fixing ring 4 and covers the fixing groove 46. A retaining ring 5 is engaged in the fixing groove 46. The retaining ring 5 has a certain elasticity and engages and fixes the braided layer 13 covering the fixing groove 46 to the fixing ring 4, thereby fixing the position of the cable through the braided layer 13. The screw sleeve 3 is sleeved on the tail of the clamp 2 so that the tail of the clamp 2 is clamped on the surface of the outer sheath 14 of the cable, thereby assisting in fixing the position of the cable through the clamping force of the tail of the clamp 2 on the cable.

[0038] refer to Figures 2-5 The cable is stripped to the required size, that is, the outer sheath 14 of the cable is stripped to expose the braided layer 13. The stripped cable is then passed through the first mounting hole 21 into the cable clamp 2. The braided layer 13 of the cable is then folded over and wrapped around the fixing ring 4. The folded braided layer 13 covering the fixing groove 46 is then used to fix this part of the braided layer 13 directly onto the fixing groove 46, thereby fixing the cable to the fixing ring 4 through the braided layer 13, thus stabilizing the position of the cable.

[0039] refer to Figures 2-5The fixing ring 4 includes an integrally formed lower limit part 41, a side pressing part 42, and an upper fixing part 43. The lower limit part 41 is located on the inner wall of the fixing ring 4 and distributed on the outer side of the braided layer 13. The side pressing part 42 is located on the end face of the fixing ring 4. The upper fixing part 43 is located on the outer side of the fixing ring 4. The fixing groove 46 is formed on the upper fixing part 43. The braided layer 13 is clamped in the fixing groove 46 by the retaining ring 5 and does not have any directional displacement. It is evenly distributed on the surface of the upper fixing part 43, which not only protects the cable braided layer 13, but also increases the number of contact points between the cable braided layer 13 and the main body 6, making the contact more sufficient. The side pressing part 42 cooperates with the main body 6 to axially compress the braided layer 13 located at the side pressing part 42, thereby fixing the position of the braided layer 13. In order to facilitate and more stably compress the braided layer 13, the side pressing part 42 is vertically arranged. The inner cavity of the main body 6 is provided with a vertically arranged platform surface 61 that cooperates with the side pressing part 42. The folded part of the braided layer 13 is located between the side pressing part 42 and the platform surface 61 of the main body 6, and the side pressing part 42 and the platform surface 61 compress each other, thereby fixing the braided layer 13 located between the side pressing part 42 and the platform surface 61 of the main body 6 and making the braided layer 13 in effective contact with the main body 6.

[0040] refer to Figure 2 and Figure 3 The lower limit part 41 is used to limit the movement space of the braided layer 13 to prevent the braided layer 13 from having too much movement space and being easily tangled or displaced. The upper fixing part 43 is used to support and fully contact the folded braided layer 13.

[0041] refer to Figure 2 and Figure 3 To further limit the cable in the clamp 2, the diameter (d) of the lower limit 41 is smaller than the diameter (D) of the first mounting hole 21, thus forming a blocking part 411 between the side of the lower limit 41 and the first mounting hole 21. The difference between the diameter of the lower limit 41 and the diameter of the first mounting hole 21 is not greater than the thickness of the outer sheath 14. Thus, the blocking part 411 matches the cross-section of the outer sheath 14 of the cable and does not affect the passage of the braided layer 13. In addition, the blocking part 411 restricts the maximum position of one end of the cable into the first mounting hole 21, thereby limiting the degree of freedom of the cable in the clamp 2. This makes the cable more stable in the clamp 2 and also prevents the braided layer 13 of the outer sheath 14 exposed by the stripped cable from being affected by the axial displacement of the cable, thus affecting the durability of the braided layer 13.

[0042] refer to Figure 4 and Figure 5In order to further improve the durability of the braided layer 13, increase its service life, and reduce the wear of the braided layer 13, a first transition portion 44 is formed between the lower limit portion 41 and the side pressure portion 42, and a second transition portion 45 is formed between the side pressure portion 42 and the upper fixing portion 43. The first transition portion 44 and the second transition portion 45 can be rounded corners.

[0043] refer to Figures 2-5 The tail of the clamp 2 includes multiple clamping plates 22 for clamping the cable. There is a deformation gap between adjacent clamping plates 22, so as to provide space for the clamping plates 22 to close together. The clamping plates 22 have clamping teeth extending from the side near the first mounting hole 21. The screw sleeve 3 is pressed and engaged with the clamping plates 22 so that the multiple clamping plates 22 move toward the cable in the first mounting hole 21 and the clamping teeth press against the outer sheath 14 of the cable.

[0044] refer to Figures 2-5 The threaded sleeve 3 has a second mounting hole 31 that allows the cable to pass through. The threaded sleeve 3 is fitted onto the clamp 2 through the second mounting hole 31 and is threaded into the clamp 2. Specifically, the outer edge of the clamp 2 has an external thread, and the threaded sleeve 3 has an internal thread. For the connection between the clamp 2, the threaded sleeve 3, and the body 6, the body 6 also has an internal thread. Therefore, the threaded sleeve 3 and the body 6 are connected to the external thread on the clamp 2, so that when the threaded sleeve 3 is tightened, the end face of the threaded sleeve 3 abuts against the end face of the body 6. The tail of the second mounting hole 31 gradually narrows to form a conical cavity 311. The conical cavity 311 serves to guide the clamping plate 22 to retract and contract. When the screw sleeve 3 is tightened, the conical cavity 311 and the end of the clamping plate 22 are pressed together to make the ends of the multiple clamping plates 22 close to the conical cavity 311 retract and contract each other, thereby pressing on the outer sheath 14 through the clamping tooth assembly. In order to facilitate a smoother release of the pressure between the screw sleeve 3 and the clamping plate 22, a contact protrusion 224 can be extended in the contact area between the clamping plate 22 and the screw sleeve 3.

[0045] refer to Figures 3-5The clamping tooth assembly includes a first clamping tooth 221, a second clamping tooth 222, and a third clamping tooth 223 arranged sequentially. The third clamping tooth 223 is located at the tail of the clamping clamp plate 22. Therefore, the second clamping tooth 222 is located between the first clamping tooth 221 and the third clamping tooth 223, and there is a gap between the first clamping tooth 221, the second clamping tooth 222, and the third clamping tooth 223. When the clamping tooth assembly does not press on the cable, the distance between the first clamping tooth 221, the second clamping tooth 222, the third clamping tooth 223 and the cable outer sheath 14 gradually increases. That is, the first clamping tooth 221, the second clamping tooth 222, and the third clamping tooth 223 are arranged at different heights. When the clamping clamp plate 22 is tilted to press on the cable outer sheath 14, the force is distributed to three points, so that the clamping clamp plate 22 can both clamp the cable and not damage it. Because the clamping plate 22 is inclined to press the cable outer sheath 14, if the three clamping teeth are in a horizontal plane in the free state, the force will be applied to the contact point of the last clamping tooth, while the force applied by the latter two clamping teeth will be smaller, which will lead to local concentration of force and damage to the cable.

[0046] Operation process: Strip the cable to the required size to expose the braided layer 13. Insert the stripped cable into the first mounting hole 21 of the clamp 2 until the cross-section of the outer sheath 14 abuts against the blocking part 411 of the fixing ring 4. Then, fold the braided layer 13 that has passed through the fixing ring 4 outward around the fixing ring 4, and make the braided layer 13 evenly distributed on the outer surface of the fixing ring 4. Then, use the retaining ring 5 to tighten the braided layer 13 in the fixing groove 46. Then, rotate the clamp 2 containing the cable into the main body 6. The fixing ring 4 with the braided layer 13 wrapped in it is pressed against the platform surface 61 of the main body 6 by the side pressure part 42, so that the braided layer 13 is in effective contact with the main body 6. Through the cooperation with the retaining ring 5, the braided layer 13 cannot be displaced in any direction and is evenly distributed on the surface of the fixing ring 4. This protects the braided layer 13 of the cable and increases the number of contact points between the braided layer 13 and the main body 6, making the contact more thorough. Finally, rotate the screw sleeve 3 onto the clamp 2 until the screw sleeve 3 fits into the body 6. During this process, the clamping plate 22 will contract as guided by the slope of the conical cavity 311 inside the screw sleeve 3. During the contraction, the clamping plate 22 will press against the outer sheath 14 of the cable in a slope shape. By using clamping teeth of different heights, the force is distributed to the three clamping teeth when the outer sheath 14 is pressed at an angle, so as to both clamp the cable tightly and not damage the cable.

[0047] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
