The base member 20 is fixed to the terminal board 11 by screws 25 . The base member 20 is composed of a pair of locking plates 21 and 21' located at the upper and lower parts, respectively, and the wire positioning sections 22 and 22' are adjacent to the locking plates 21 and 21', respectively.

The clamping members 23 and 23 ′ fix the power cord 100 on the terminal board 11 . The splint members 23 and 23' include joint sections 23a and 23a' locked in the locking plates 21 and 21', and structural holes 23b and 23b' opposite to the joint sections 23a and 23a'.

The conventional cord clamp assembly described above clamps the power cord 100 in the following manner.

First, the joint sections 23a and 23a' of the splint members 23 and 23' are respectively locked in the locking plates 21 and 21', so that the wire clamp 100 is in the state of being fixed in the positioning sections 22 and 22', and then, the screw Through the combination holes 23b, 23b', the splint members 23 and 23' are fixed on the base member 20. Therefore, the power cord 100 is securely clamped by the clamping plate members 23 and 23' without being separated therefrom.

However, in the conventional wire clamp assembly, the clamping plate members 23 and 23' are in a state of being separated from the base member 20 before being fixed by screws. In this way, the assembly process of the splint parts 23 and 23' is very troublesome, and there is even a defect that the components to be assembled will be lost before assembly. In addition, since the base member 20 and the splint members 23 and 23' are temporarily assembled before installing the compressor in an air conditioner, refrigerator, etc., in order to house the power cord 100, the splint members 23 and 23' should be disassembled from the base member 20. down.

The object of the present invention is to provide a wire clip assembly which has a simple structure, is easy to assemble and prevents possible loss of components.

Above-mentioned object is achieved by wire clamp assembly according to the present invention, and it comprises a base member; Clamping plate, is connected on this base member by a coupling device to support power cord; And a pre-assembled device, makes clamping plate by The combination device is not separated from the base member before coupling.

The base member includes a corresponding support portion that cooperates with the guide portion to define the power cord securing portion therebetween. The leading part is longer than the supporting part by at least one diameter of the power cord. The guide portion is preferably in the shape of a hollow cylinder.

According to the present invention, since the splint and the base are in a pre-assembled state, the splint will not be separated from the base. Furthermore, since the clamping process is performed in a state where the head portions of the clamping plate members are respectively inserted into the guide portions of the base member, the assembly process becomes very convenient.

The above objects and advantages will be more apparent by describing the preferred embodiment of the present invention with reference to the accompanying drawings, in which:

Figure 1 is an exploded perspective view of a common wire clip assembly;

Figure 2 is an exploded perspective view of the cable clamp assembly according to the preferred embodiment of the present invention;

Figure 3 is a perspective view of the wire clamp assembly in an assembled state according to the preferred embodiment of the present invention;

Figure 2 shows a wire clamp assembly according to a preferred embodiment of the present invention.

As shown, the wire clip assembly according to the preferred embodiment of the present invention includes a base member 40, splint members 43 and 43' coupled with the base member 40, and a pre-assembled device.

The pre-assembled device comprises guide portions 42 and 42', and head portions 43b and 43b'. The guide portions 42 and 42' protrude from the base member 40, respectively. The head portions 43b and 43b' are formed on the sides of the main body portions 43c and 43c' of the clamping plate members 43 and 43', respectively.

The guide portions 42 and 42' are hollow cylinders with longitudinal openings. The longitudinal openings are formed with a pair of protrusions 42a and 42a' at their ends, respectively.

The diameter of the head portions 43b and 43b' is slightly smaller than the diameter of the guide portions 42 and 42'. The head portions 43b and 43b' are inserted into the guide portions 42 and 42'. The connection portions 43d and 43d' connect the head portions 42b and 43b' with the main bodies 43c and 43c' of the jaw members 43 and 43'. The connection portions 43d and 43d' have a width smaller than the longitudinal opening width of the guide portions 42 and 42'. Also, the width of the connection portions 43d and 43d' is greater than the distance between the protrusions 42a and 42a' formed on the longitudinal opening. Thus, when the head portions 43b and 43b' are inserted into the guide portions 42 and 42', the connection portions 43d and 43d' pass through the longitudinal openings of the guide portions 42 and 42'.

In addition, the base member 40 has support portions 41 and 41' protruding therefrom. Support portions 41 and 41' cooperate with respective guide portions 42 and 42' to define respective power cord positioning portions 44 and 44' therebetween. The guide portions 42 and 42' are longer than the support portions 41 and 41' by at least one diameter of the power cord 100. As shown in FIG.

After being inserted into the guide parts 42 and 42', the head parts 43b and 43b' are free to move in the longitudinal direction of the guide parts 42 and 42'. However, since both sides of the connecting parts 43d and 43d' are blocked by a pair of protrusions 42a and 42a', the connecting parts 43d and 43d' are formed between the main bodies 43c and 43c' and the head parts 43b and 43b of the clamping plate members 43 and 43'. ', the ridges 42a and 42a' are formed at the guide portions 42 and 42' and the longitudinal openings, so that the head portions 43b and 43b' are not separated from the guide portions 42 and 42'. Preferably, the connecting portions 43d and 43d' and the protrusions 42a and 42a' of the guide portions 42 and 42' are chamfered so that the head portions 43b and 43b' can be smoothly inserted into the guide portions 42 and 42'.

In addition, corresponding intervals can be formed between the supports 43a and 43a' on the splint parts 43 and 43' disposed in the guide parts 42 and 42' and the support parts 41 and 41' of the base part 40, respectively, and the support 43a and the support part 41 Or the width of each interval between the support 43a' and the support portion 41' is equivalent to the diameter of at least one power cord.

The power cord 100 is disposed in the positioning portions 44 and 44' of the base member 40 through corresponding gaps between the support portions 41 and 41' and the support portions 43a and 43a'. Screws 45 are passed through holes in the heads 43b and 43b' to couple the base member 40 to the terminal block 31. As shown in FIG. Accordingly, the power cord 100 is clamped by the wire positioning portions 44 and 44' of the base member 40 and the clamping plate members 43 and 43'. The support portions 41 and 41' prevent the power cord 100 from being disengaged from the wire positioning portions 44 and 44' along the length direction of the splint members 43 and 43'.

As mentioned above, the splint part is in a pre-assembled state with the base part, and the splint part will not be separated from the base part. Moreover, since the power cord is in a clamped state, the head of the splint member is inserted into the guide portion, so assembly is facilitated.

Although the invention has been particularly described with reference to a preferred embodiment, those skilled in the art will understand that various changes in construction and components may be made without departing from the spirit and scope of the invention as defined by the appended claims.
