Fig. 1 and 2 provide an improved cable clamp, the cable clamp 10 being composed of a connection base 11 and a connection element 13. The connecting base 11 is provided with a buckle 12, and the buckle 12 is configured to extend along a direction departing from the connecting base 11 and is clamped with a through hole arranged on the bracket to fixedly connect the connecting base 11. The bracket is arranged in the air conditioner shell or is a component of the air conditioner shell. The connecting element 13 is rotatable relative to the connecting base 11. The connecting element 13 has a guide 14, the guide 14 being at least partially spaced from the connection base 11. The cross section of the guide 14 can be designed as a substantially optimum arc or as a rounded rectangle. The guide portion 14 of the connecting member 13 or a portion (for example, the upper half portion of the major arc) of the guide portion 14 of the connecting member 13 and the connecting base 11 are arranged in parallel up and down with a predetermined interval therebetween with respect to the longitudinal direction of the connecting base 11, and the guide portion 14 and the connecting base 11 commonly hold the cable inserted from the predetermined interval. The utility model provides a cable anchor clamps 10 can ensure on the one hand that the cable that penetrates from setting for the interval can pull in a flexible way and remove, and the position of the operating personnel of being convenient for adjustment cable avoids kinking, and on the other hand can be earlier be fixed in the support with connecting base 11 under the prerequisite that need not to use the screwdriver, is difficult for dropping, and after-sale installation is more convenient, in addition, through buckle 12 fixed connection base 11, can also reach the purpose of repeated installation and dismantlement, and cable anchor clamps 10's rate of reuse is higher. The fastening of the set spacing is preferably effected by means of a catch provided on the connection base 11, by means of which the connection element 13 is limited, and the operator can also add, if necessary, a bolt reinforcement, without limitation.

The connection base 11 and the connection element 13 may be integrally formed through an injection molding process, or may be detachably pivotally connected. The latter will be described in detail below.

The stable connection of connecting base 11 and support is the first step of accomplishing the cable installation, in order to ensure the high accuracy cooperation between the two and connect the compactness, the utility model discloses design the buckle very much. The catch comprises at least one jaw, exemplified by jaws 12-11. As shown in fig. 3-5, jaws 12-11 include jaw arms 15 and jaw ends 19.

Compared with a straight arm, the tapered arm can allow larger deformation amount and has better structural strength on the premise that the section area of one end close to the connecting base 11 is the same. A jaw end 19 is formed at the free end of the jaw arm 15, i.e. the end remote from the connection base 11. The jaw end 19 has a snap-in end face 16, which snap-in end face 16 is in contact with the holder in the assembled state, so that the connection base 11 is attached to the holder. The included angle between the clamping end face 16 and the claw arm 15 is larger than or equal to 90 degrees. The angle between the clamping end face 16 and the jaw arm 15 can be designed according to the frequency of removal of the cable clamp. The jaw end 19 is further designed with a guide end surface 17, and the included angle between the guide end surface 17 and the jaw arm 15 is less than or equal to 30 degrees, so that the installation by an operator is convenient. In order to avoid stress concentration at the root of the claws 12 to 11 and breakage during assembly or disassembly, it is preferable to provide rounded corners having a radius equal to or larger than half the width of the claw arm 15 at the positions of the claw arm 15 and the connection base 11.

To evenly carry the load and avoid deformation of the bracket, as shown in fig. 1, in an alternative embodiment. The catch comprises a first jaw 12-11 and a second jaw 12-12. The first jaw 12-11 has a first snap-in end surface and the second jaw 12-12 has a second snap-in end surface. The first jaw 12-11 and the second jaw 12-11 are spaced apart from each other and are juxtaposed along a length of the connection base 11 (as indicated by arrow L in fig. 1), and the first and second engagement end surfaces extend away from each other (as indicated by arrows D1 and D2 in fig. 1).

Alternatively, in another alternative embodiment, as shown in FIG. 7, a plurality of catches 12 are provided. The plurality of clips 12 are arranged in parallel with a predetermined interval therebetween along the longitudinal direction of the connection base 11. Each catch comprises a first jaw 12-21 and a second jaw 12-22, the first jaw 12-21 having a first catch end face and the second jaw 12-22 having a second catch end face. The first claws 12 to 11 and the second claws 12 to 11 are spaced apart from each other at a predetermined interval and arranged side by side in the width direction of the coupling base 11 (as indicated by arrows W in fig. 7). The first and second snap end faces extend away from each other (as indicated by arrows D1 and D2 in fig. 7).

The connection base and the connection element may be detachably pivotally connected by means of a pivot or hinge provided at one end of the connection base (as shown at 18 in fig. 7), in such a way that the connection element can be adapted to a plurality of connection bases. As shown in fig. 6 and 7, the connection base includes a first connection base 11-1 and a second connection base 11-2, wherein the first connection base 11-1 is provided with a first snap 12-1, the first snap 12-1 includes at least two jaws (as shown by 12-11 and 12-12 in fig. 6), the jaws 12-11 and 12-12 have a set interval therebetween and are juxtaposed in a length direction (as shown by an arrow L in fig. 6) of the first connection base 11-1. The second connecting base 11-2 is provided with at least two second buckles 12-2; the second buckles 12-2 are spaced apart from each other and arranged in parallel along the length direction (as indicated by an arrow L in fig. 7) of the second connection base 11-2; the second buckle 12-2 includes at least two jaws 12-21 and 12-22, the jaws 12-21 and 12-22 having a set interval therebetween and being juxtaposed in a width direction (as indicated by an arrow W in fig. 7) of the second coupling base 11-2, and one of the first coupling base 11-1 and the second coupling base 11-2 is detachably pivotally coupled to the connection member. By adopting the structure, a plurality of through holes can be formed in different positions of the bracket in advance, and field installation personnel can select one of the first connecting base 11-1 and the second connecting base 11-2 for installation according to the field construction requirement or the strength required by cable installation.
