Description

Technical Field

[0001] The present invention relates to the technical field of cables, and in particular to a connection mechanism and an assembly method for cables with a braided layer. Background Art

[0002] With the rapid development of the semiconductor industry, the actual power used in chip manufacturing, chip testing, and chip packaging is getting higher and higher. The demand for high-power RF transmission cables is increasing day by day. Conventional high-power cable wiring connection methods are as follows: Figure 1 As shown, the cable braiding layer is compressed by using the inclined surface of the wire clamp and the main body, and then the cable outer sheath is clamped by an O-ring at the tail end or the wire clamp is used to hold the wire at a single point, thereby fixing the position of the cable as a whole.

[0003] However, this conventional wiring method will cause the braided layer to be scattered, resulting in metal wires being inserted into the cavity during the wiring process. In addition, as the cable braid is screwed into the main body, the scattered braid will be scattered due to friction and concentrated in one place to generate pulling force, thus destroying the braid. All these will affect the voltage resistance, causing personnel to repeatedly confirm the installation. Summary of the invention

[0004] A first aspect of the present invention provides a connection mechanism for a cable having a braided layer, which can protect the overall structure and performance of the cable and ensure the holding force of the connection mechanism on the cable.

[0011] Preferably, the tail of the wire clamp includes a plurality of clamping plates for clamping the cable, a deformation gap is left between adjacent clamping plates, a clamping tooth group extends from one side of the clamping plate close to the first mounting hole, and the screw sleeve is squeezed and fitted with the clamping plate so that the plurality of clamping plates are moved toward the cable in the first mounting hole and the clamping tooth group is pressed on the outer sheath of the cable.

[0012] Preferably, the screw sleeve is provided with a second mounting hole through which the cable can pass, and the screw sleeve is mounted on the wire clamp through the second mounting hole.

[0047] Example:

[0048] like Figure 2 As shown, the cable includes a conductor 11 , an insulating layer 12 surrounding the conductor 11 , a braided layer 13 covering the insulating layer 12 , and an outer sheath 14 wrapping the braided layer 13 .

[0049] refer to Figure 2-Figure 5 , a connection mechanism for a cable with a braided layer, comprising: a wire clamp 2 and a screw sleeve 3, the wire clamp 2 axially opens a first mounting hole 21, one end of the cable can be inserted into the first mounting hole 21, the wire clamp 2 is extended with a fixing ring 4 coaxial with the first mounting hole 21 at one end close to the main body 6, a fixing groove 46 is opened on the outer surface of the fixing ring 4, the braided layer 13 of the cable is folded around the end surface of the fixing ring 4 and covers the fixing groove 46, a clamping ring 5 is clamped on the fixing groove 46, the clamping ring 5 has a certain elastic force, the clamping ring 5 clamps and fixes the braided layer 13 covering the fixing groove 46 on 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 wire clamp 2 so that the tail of the wire clamp 2 is clamped on the surface of the outer sheath 14 of the cable, thereby auxiliary fixing the position of the cable through the clamping force of the tail of the wire clamp 2 on the cable.

[0050] refer to Figure 2-Figure 5, strip the cable according to the required size, that is, peel off the outer sheath 14 of the cable to expose the braided layer 13, insert the stripped cable into the wire clamp 2 through the first mounting hole 21, and then fold the braided layer 13 of the cable and wrap it around the fixing ring 4, the braided layer 13 folded and wrapped around the fixing ring 4 covers part of the fixing groove 46, and then use the clamp 5 to directly fix this part of the braided layer 13 on the fixing groove 46, so that the cable is fixed on the fixing ring 4 through the braided layer 13, thereby stabilizing the position of the cable.

[0051] refer to Figure 2-Figure 5 The fixed ring mouth 4 includes an integrally formed lower limit portion 41, a side pressure portion 42 and an upper fixing portion 43. The lower limit portion 41 is located at the inner wall of the fixed ring mouth 4 and distributed on the outside of the braided layer 13. The side pressure portion 42 is located at the end surface of the fixed ring mouth 4. The upper fixing portion 43 is located on the outer surface of the fixed ring mouth 4. The fixing groove 46 is opened on the upper fixing portion 43. The braided layer 13 is clamped in the fixing groove 46 by the clamping ring 5 without any directional displacement and is evenly distributed on the surface of the upper fixing portion 43, which not only protects the cable braided layer 13 but also increases the contact points between the cable braided layer 13 and the main body 6, and the contact is more sufficient. The side pressure portion 42 cooperates with the main body 6 to axially squeeze the braided layer 13 at the side pressure portion 42 and thus fix the position of the braided layer 13. In order to conveniently and more stably squeeze the braided layer 13, the side pressure portion 42 is vertically arranged, and a vertically arranged platform surface 61 cooperating with the side pressure portion 42 is provided in the inner cavity of the main body 6. The folded part of the braided layer 13 is between the side pressure portion 42 and the platform surface 61 of the main body 6, and the side pressure portion 42 and the platform surface 61 squeeze each other, thereby fixing the braided layer 13 between the side pressure portion 42 and the platform surface 61 of the main body 6 and making the braided layer 13 effectively contact with part of the main body 6.

[0052] refer to Figure 2 and Figure 3 The lower limit portion 41 is used to limit the activity space of the braided layer 13 to prevent the braided layer 13 from having too much activity space and being easily entangled or displaced. The upper fixing portion 43 is used to bear and fully contact the folded braided layer 13.

[0053] refer to Figure 2 and Figure 3In order to further limit the cable in the wire clamp 2, the diameter (d) at the lower limit portion 41 is smaller than the diameter (D) of the first mounting hole 21, so that a blocking portion 411 is formed between the side of the lower limit portion 41 and the first mounting hole 21, and the difference between the diameter of the lower limit portion 41 and the diameter of the first mounting hole 21 is not greater than the thickness of the outer sheath 14, so that the blocking portion 411 matches the cross-section of the outer sheath 14 of the cable and does not affect the passage of the braided layer 13, and then the maximum position of one end of the cable extending into the first mounting hole 21 is limited by the blocking portion 411, thereby limiting the freedom of the cable in the wire clamp 2, so that the cable is more stably placed in the wire clamp 2, and can also prevent the braided layer 13 of the outer sheath 14 exposed by the stripping from affecting the durability of the braided layer 13 due to the random axial displacement of the cable.

[0054] refer to Figure 4 and Figure 5 In 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.

[0055] refer to Figure 2-Figure 5 The tail of the wire clamp 2 includes a plurality of clamping plates 22 for clamping the cable, and a deformation gap is left between adjacent clamping plates 22, so as to provide space for the clamping plates 22 to be retracted together. A clamping tooth group extends from one side of the clamping plate 22 close to the first mounting hole 21, and the screw sleeve 3 is squeezed and matched with the clamping plate 22 so that the plurality of clamping plates 22 are moved toward the cable in the first mounting hole 21 and the clamping tooth group is pressed on the outer sheath 14 of the cable.

[0056] refer to Figure 2-Figure 5 The screw sleeve 3 is provided with a second mounting hole 31 through which the cable can pass. The screw sleeve 3 is sleeved on the wire clamp 2 through the second mounting hole 31 and is threadedly matched with the wire clamp 2. Specifically, the outer edge of the wire clamp 2 is provided with an external thread, and the screw sleeve 3 is provided with an internal thread. In order to connect the wire clamp 2, the screw sleeve 3, and the main body 6, the main body 6 is also provided with an internal thread. Therefore, the screw sleeve 3 and the main body 6 are connected to the external thread on the wire clamp 2 together, so that when the screw sleeve 3 is tightened, the end face of the screw sleeve 3 abuts against the end face of the main body 6. The tail of the second mounting hole 31 gradually narrows to form a tapered cavity 311, which serves to guide the clamping clamp 22 to retract and shrink. When the screw sleeve 3 is assembled, the tapered cavity 311 and the end of the clamping clamp 22 are squeezed and matched to make the ends of the multiple clamping clamps 22 close to the tapered cavity 311 retract and shrink to each other, thereby being pressed on the outer sheath 14 through the clamping tooth group. In order to facilitate smoother extrusion and release between the screw sleeve 3 and the clamping clamp 22, a contact protrusion 224 can be extended in the contact area between the clamping clamp 22 and the screw sleeve 3.

[0057] refer to Figure 3-Figure 5 The clamping tooth group includes a first clamping tooth 221, a second clamping tooth 222, and a third clamping tooth 223 which are arranged in sequence. The third clamping tooth 223 is arranged at the tail of the clamping clamping plate 22, so the second clamping tooth 222 is 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 group does not press 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 clamping plate 22 tilts to press the cable outer sheath 14, the force is dispersed to three points, so that the clamping clamping plate 22 can clamp the cable without damaging the cable. Because the clamping clamp 22 is made to press the cable outer sheath 14 in a sloped shape, if the three clamping teeth are in a horizontal plane in a free state, the force will be applied to the contact point of the last clamping tooth, while the force applied by the two rear clamping teeth will be smaller, resulting in local concentration of force and damage to the cable.

[0058] Operation process: strip the cable according to the required size and expose the braided layer 13, insert the stripped cable into the first mounting hole 21 of the wire clamp 2 until the cross section of the outer sheath 14 abuts against the blocking portion 411 of the fixed ring 4, then fold the braided layer 13 passing through the fixed ring 4 around the outside of the fixed ring 4, and make the braided layer 13 evenly distributed on the outer side of the fixed ring 4, and then tighten the braided layer 13 in the fixing groove 46 through the clamp 5, and then rotate the wire clamp 2 with the cable into the main body 6, and squeeze the braided layer 13 on the platform surface 61 of the main body 6 through the side pressure portion 42 of the fixed ring 4, and make the braided layer 13 effectively contact with part of the main body 6, and through the cooperation with the clamp 5, the braided layer 13 cannot be displaced in any direction and is evenly distributed on the surface of the fixed ring 4, thereby protecting the braided layer 13 of the cable and making the contact points between the braided layer 13 and the main body 6 more and more sufficient. Finally, the screw sleeve 3 is rotated and installed on the wire clamp 2 until the screw sleeve 3 fits with the main body 6. During this process, the clamping plate 22 will shrink along with the guidance of the slope of the conical cavity 311 inside the screw sleeve 3, and in the process of shrinkage, the clamping plate 22 will be pressed on the outer sheath 14 of the cable in a slope shape, and the clamping teeth with different heights will disperse the force to the three clamping teeth when obliquely pressing the outer sheath 14, so that the cable can be clamped without damaging the cable.

[0059] The present invention also discloses an assembly method for a connection mechanism having a braided cable, comprising the following steps:

[0060] a. Provide a connection mechanism;

[0061] b. Providing a cable having at least a braided layer 13;

[0062] c. Strip the cable until the braided layer 13 is exposed;

[0063] d. Insert the stripped cable into the first mounting hole 21 of the wire clamp 2;

[0064] e. Fold the braided layer 13 of the cable around the fixed ring 4;

[0065] f. Use the clasp 5 to snap the folded braided layer 13 into the fixing groove 46 and fix it;

[0066] g. Install the wire clamp 2 into the main body 6;

[0067] h. Squeeze the fixed ring 4 and the main body 6;

[0068] i. Put the screw sleeve 3 onto the wire clamp 2;

[0069] j. Squeeze the screw sleeve 3 against the clamping plate 22 at the tail of the wire clamp 2 and make the clamping plate 22 clamp the cable.
