[0024] The present application embodiment provides a cable clamp, referring to Figure 1-Figure 3 , including: a snap-in assembly 10 for snapping in a first cable; at least one snap-in socket 20, the snap-in socket 20 being provided with a snap-in groove 201 for snapping in a second cable; a snap-in buckle 210 being provided at one end of the snap-in socket 20, and a snap-in groove 202 detachably matched with the snap-in buckle 210 being provided at the other end of the snap-in socket 20 and the snap-in assembly 10.

[0025] In this embodiment, the clamping assembly 10 is used to clamp the first cable. The clamping seat 20 and the clamping assembly 10, as well as the clamping seat 20 and the clamping seat 20, can be detachably connected with the clamping slot 202 through the buckle 210. The number of the clamping seats 20 can be flexibly determined according to the number of the second cables. When the number of the second cables is one, one clamping seat 20 is installed on the clamping assembly 10 through the detachable structure of the buckle 210 and the clamping slot 202, and the second cable is clamped in the clamping slot 201; when the number of the second cables is multiple, multiple clamping seats 20 are assembled in sequence through the buckle 210 and the clamping slot 202, so that the cable clamp can be adaptively adjusted according to the laying quantity requirements of the second cables, reducing the number of cable clamps used to reduce the laying cost.

[0026] By utilizing the structure of the buckle 210 and the card slot 202, the card seat 20 can be horizontally expanded on the card assembly 10, or another card seat 20 can be horizontally expanded on the card seat 20, so that the number of card slots 201 is horizontally increased, and the card assembly 10 and the card seat 20 are modularly combined according to the number of second cables actually laid, and the structure of the cable fixture is flexibly adjusted. When the number of second cables needs to be reduced, the card seat 20 away from the card assembly 10 can be removed from the adjacent card seat 20, and the operation is simple.

[0027] Furthermore, the body of the holder 20 may be in a rectangular parallelepiped shape, and the opening of the wire slot 201 is located at one end surface of the holder 20. The cable is usually a flexible cylinder, and the surface of the wire slot 201 may be arc-shaped to adapt to the shape of the second cable.

[0028] The buckle 210 and the slot 202 on the card holder 20 are respectively located on both sides of the axis of the wire slot 201, and the arrangement direction of the buckle 210 and the slot 202 is perpendicular to the extension direction of the wire slot 201. Figure 2 A buckle 210 is provided at the left end of the card holder 20 , a card slot 202 is provided at the right end of the card holder 20 , a wire card slot 201 is located between the buckle 210 and the card slot 202 , and an opening of the wire card slot 201 faces upward.

[0029] It should be noted that the directions "left" and "right" in the embodiments of this application specification refer to Figure 1 and Figure 2 The X-axis direction in the above diagram refers to the “up” and “down” directions. Figure 1 and Figure 2 The Z-axis direction.

[0030] As an optional implementation, refer to Figure 2 and Figure 3 The buckle 210 includes a first clamping portion 2110 and a second clamping portion 2120 ; the clamping slot 202 includes a first slot body 2021 matched with the first clamping portion 2110 and a second slot body 2022 matched with the second clamping portion 2120 .

[0031] In this embodiment, the first clamping portion 2110 and the second clamping portion 2120 can be arranged in sequence along the extension direction of the wire clamping slot 201; compared with one clamping portion, two clamping portions can increase the connection strength between the clamping seat 20 and the clamping assembly 10 or the connection strength between the clamping seats 20 and the clamping seats 20.

[0032] As an optional implementation, refer to Figure 2 and Figure 3 The first clamping portion 2110 extends outward from the body of the card holder 20 , and the end of the first clamping portion 2110 faces the body of the card holder 20 .

[0033] The extension direction of the first clamping portion 2110 is consistent with the opening direction of the wire clamping slot 201. The first clamping portion 2110 may be L-shaped. When the first clamping portion 2110 is embedded in the first slot 2021, the end of the first clamping portion 2110 may hook the clamping assembly 10 to prevent the first clamping portion 2110 from being separated from the first slot 2021.

[0034] As an optional implementation, refer to Figure 2 and Figure 3 The surface of the card holder 20 close to the first clamping portion 2110 is the mounting surface 203 , the mounting surface 203 is an arc-shaped surface, and the center of curvature of the mounting surface 203 is far away from the first clamping portion 2110 .

[0035] In this embodiment, the opening size of the wire slot 201 is smaller than the diameter of the second cable. When the second cable is inserted into the wire slot 201, the second cable will squeeze the card holder 20 to cause deformation. The mounting surface 203 is an arc surface, so that the stress concentration generated on the mounting surface 203 when the card holder 20 is deformed is small, thereby preventing the card holder 20 from breaking. The mounting surface 203 can be co-centered with the wire slot 201, so that when the card holder 20 is deformed, the deformation direction of the mounting surface 203 is consistent with the deformation direction of the inner side surface of the wire slot 201.

[0036] The body of the holder 20 , the first clamping portion 2110 , and the second clamping portion 2120 may be integrally formed and made of a material having elastic deformation capability.

[0037] The second clamping portion 2120 is greater than the length of the first clamping portion 2110 in the left-right direction. When the buckle 210 is matched with the clamping slot 202 , the second clamping portion 2120 first enters the second slot 2022 , and then the first clamping portion 2110 enters the first slot 2021 .

[0038] The distance between the opening of the first slot 2021 and the bottom surface of the card holder 20 is smaller than the distance between the end of the first clamping portion 2110 and the bottom surface of the card holder 20. When the card holder 20 is connected to the clamping assembly 10, the card holder 20 can be pressed to deform to the left at the installation surface 203, so that the first clamping portion 2110 is close to the bottom surface of the card holder 20, so that the first clamping portion 2110 can smoothly enter the opening of the first slot 2021. It should be noted that the bottom surface of the card holder 20 here refers to the end surface of the card holder 20 away from the opening of the wire clamping slot 201.

[0039] When removing the buckle 210 from the slot 202, the snap assembly 10 or the socket 20 can be manually pried to increase the opening of the slot 202, so that the limit block 220 can be separated from the limit slot 21201, and the part of the snap assembly 10 or the socket 20 that cooperates with the first snap portion 2110 can be separated from the first snap portion 2110, thereby removing the buckle 210 from the slot 202.

[0040] As an optional implementation, a cross-sectional area of ​​the second clamping portion 2120 gradually decreases from the main body of the clamping seat 20 toward the end of the second clamping portion 2120 .

[0041] In this embodiment, reference Figure 2 The cross-sectional area of ​​the second clamping portion 2120 refers to the cross-sectional area of ​​the second clamping portion 2120 in the XOY plane. The second clamping portion 2120 is in a sharp angle shape. When the second clamping portion 2120 is inserted into the second slot 2022, the surface of the second clamping portion 2120 gradually abuts against the slot wall of the second slot 2022 from loose to tight.

[0042] As an optional implementation, refer to Figure 2 and Figure 3 The second clamping part 2120 is provided with a limiting groove 21201, and the clamping assembly 10 and the clamping seat 20 are both provided with a limiting block 220 that cooperates with the limiting groove 21201. After the limiting block 220 cooperates with the limiting groove 21201, the second clamping part 2120 can be prevented from being separated from the second slot body 2022.

[0043] The reason why the limiting groove 21201 is provided on the second clamping part 2120 instead of the limiting block 220 is that the portion of the second clamping part 2120 corresponding to the limiting groove 21201 has a larger size in the vertical direction, and the limiting groove 21201 has a smaller effect on the strength of the second clamping part 2120. However, the portion of the clamping base 20 corresponding to the second slot body 2022 has a smaller thickness. If the limiting groove 21201 is provided on the clamping base 20, the limiting groove 21201 will be connected to the second slot body 2022, resulting in a reduced strength of the portion of the clamping base 20 corresponding to the second slot body 2022, which is prone to fracture.

[0044] As an optional implementation, refer to Figure 2 and Figure 3 The surface of the second clamping portion 2120 away from the first clamping portion 2110 is the first contact surface 21202 , and the notch of the limiting groove 21201 is located on the first contact surface 21202 ; the extending direction of the limiting groove 21201 obliquely intersects with the first contact surface 21202 .

[0045] In this embodiment, the first contact surface 21202 is a flat surface, and the first contact surface 21202 is parallel to the bottom surface of the card holder 20. The shape of the limit block 220 is similar to a hook, and the limit groove 21201 extends obliquely toward the end of the second clamping portion 2120, so that the length direction of the limit block 220 is arranged at an angle with the first contact surface 21202, and the angle is an acute angle. Compared with the extension direction of the limit groove 21201 being perpendicular to the first contact surface 21202, the limit groove 21201 and the limit block 220 in this embodiment cooperate to further improve the clamping strength of the limit groove 21201 and the limit block 220.

[0046] As an optional implementation, refer to Figure 2 and Figure 3 The surface of the second clamping portion 2120 close to the first clamping portion 2110 is a second contact surface 21203 . The second contact surface 21203 is an arc-shaped surface, and the center of curvature of the second contact surface 21203 is far away from the first contact surface 21202 .

[0047] In this embodiment, in the same card holder 20, the second slot body 2022 is located at the lower right corner of the wire clamping slot 201. Since the wire clamping slot 201 is an arc-shaped slot, the side wall of the second slot body 2022 close to the wire clamping slot 201 is an arc-shaped surface, and the arc-shaped surface and the inner side surface of the wire clamping slot 201 can be co-centered. Therefore, the second contact surface 21203 is designed as an arc-shaped surface so that the second clamping portion 2120 and the second slot body 2022 cooperate with each other.

[0048] As an optional implementation, refer to Figure 2The card assembly 10 is provided with at least one group of symmetrically distributed card slots 202; after a group of card seats 20 are connected to the card assembly 10, the end surfaces of a group of card seats 20 away from the opening of the card slot 201 abut against each other.

[0049] In this embodiment, a pair of slots 202 are arranged on the clamping assembly 10 along the vertical direction. When the two clamping seats 20 are connected to the clamping assembly 10 through the buckle 210 and the slots 202, the bottom surfaces of the two clamping seats 20 abut against each other, so that the two clamping seats 20 can support each other after clamping the second cable. The clamping slot 201 of the lower clamping seat 20 opens downward, and the second cable on the lower clamping seat 20 has a tendency to break away from the clamping slot 201 downward. The second cable breaking away from the clamping slot 201 will cause the right end of the clamping seat 20 to deform, and then cause the bottom surface of the clamping seat 20 to bend and deform, and the bending direction is away from the opening direction of the clamping slot 201. At this time, since the bottom surfaces of the two clamping seats 20 abut against each other, the upper clamping seat 20 can limit the bending of the bottom surface of the lower clamping seat 20. Therefore, the abutment of the two clamping seats 20 can prevent the second cable from breaking away from the clamping slot 201 to a certain extent.

[0050] It should be noted that the left end of the socket 20 is the end where the buckle 210 is located, and the right end of the socket 20 is the end where the slot 202 is located. The strength of the right end of the socket 20 is less than the strength of the left end of the socket 20, so in the process of the second cable detaching from the cable slot 201, the right end of the socket 20 is more likely to deform than the left end.

[0051] The card assembly 10 is provided with two card slots 202 in the Z-axis direction so as to longitudinally expand the card holder 20 on the card assembly 10 . The number of card slots 202 on the card assembly 10 can be determined according to the dimensions of the card assembly 10 and the card holder 20 in the Z-axis direction.

[0052] As an optional implementation, refer to Figure 3 A positioning block 230 and a positioning groove 204 are provided at the end of the card holder 20 away from the wire clamping groove 201 , and the positioning block 230 of the card holder 20 can be embedded in the positioning groove 204 of another card holder 20 .

[0053] In this embodiment, on the same card holder 20, the connection direction of the buckle 210 and the card slot 202 is parallel to the positioning block 230, so that when the card holder 20 is installed or disassembled with the card connection assembly 10 or another card holder 20, the cooperation between the positioning block 230 and the positioning slot 204 will not restrict the movement of the card holder 20.

[0054] When the two card holders 20 on the upper and lower sides are in contact with each other, the positioning block 230 of one card holder 20 is embedded in the positioning groove 204 of the other card holder 20, so that the two card holders 20 will not deflect around the X axis. In addition, the positioning block 230 increases the thickness of the bottom of the card holder 20, thereby preventing the bottom of the card holder 20 from bending and deforming. It should be noted that the bottom of the card holder 20 refers to the part of the card holder 20 close to the bottom surface of the card holder 20, especially the part between the bottom of the card slot 201 and the bottom surface of the card holder 20.

[0055] The above description is only an optional embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
