Abstract
Description
Technical Field
[0001] This utility model relates to the field of equipment connection cable technology, and in particular to an easy-to-install and identify connection cable assembly. Background Technology
[0002] Cable assemblies are devices used to connect equipment to each other or between equipment circuits. Traditional cable assemblies have a relatively simple structure, but they suffer from problems such as unclear directional selection at the installation ends and inconvenience. Summary of the Invention
[0003] To address the aforementioned technical problem of unclear installation orientation, this utility model provides an easily installable and identifiable connector assembly.
[0004] The technical solution of this utility model is as follows:
[0005] An easy-to-install and identifiable connector assembly includes a wire harness with square copper contacts and O-type copper contacts at both ends. Each square and O-type copper contact includes a connecting part and a fixing part. The head of the connecting part is square or O-shaped. The fixing part includes a retainer and a retaining strip. The retainer has a retaining strip at the rear and there is a gap between the retainer and the retaining strip. The square copper contact is covered with a sheath b, and the O-type copper contact is covered with a sheath a. The connecting part has a round hole.
[0006] The card holder and card strip are arc-shaped, with the height of the card strip greater than the height of the card holder and the width of the card strip greater than the width of the card holder.
[0007] The inner wall of the card holder is provided with three protruding strips.
[0008] The inner wall of the sheath b is provided with a limiting step, and a limiting inclined wall is provided in front of the limiting step. The locking strip is located between the limiting step and the limiting inclined wall.
[0009] The wire harness is provided with a sleeve.
[0010] The top of the card strip is chamfered and has a V-shaped cross-section, while the card seat has a U-shaped cross-section.
[0011] The technical solution of this utility model has a novel structure and a clever and simple design. The square copper contacts and O-type copper contacts at both ends are easy to distinguish and identify. Moreover, the sheath b of the square copper contacts and the sheath a of the O-type copper contacts are not the same in shape. Sheath a and sheath b not only help to fix the wire harness and the two types of copper contacts, but also play a role in flame retardancy. The clips of the two types of copper contacts play a role in fixing the wire harness. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example
[0017] like Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, an easy-to-install and identifiable connecting wire assembly includes a wire harness 4. The wire harness 4 has a square copper contact 1 and an O-type copper contact 6 at both ends. The square copper contact 1 and the O-type copper contact 6 each include a connecting part and a fixing part. The head of the connecting part is square or O-shaped. The fixing part includes a retainer 2 and a retaining strip 7. The retainer 2 has a retaining strip 7 at its rear, and there is a gap between the retainer 2 and the retaining strip 7. The square copper contact 1 is covered with a sheath b9, and the O-type copper contact 6 is covered with a sheath a5. The connecting part has a round hole.
[0018] The card holder 2 and the card strip 7 are arc-shaped, with the height of the card strip 7 being greater than the height of the card holder 2 and the width of the card strip 7 being greater than the width of the card holder 2.
[0019] The inner wall of the card holder 2 is provided with three protruding strips 8.
[0020] The inner wall of the sheath b9 is provided with a limiting step 10, and a limiting inclined wall 11 is provided on the front side of the limiting step 10. The locking strip 7 is located between the limiting step and the limiting inclined wall 11.
[0021] The wire harness 4 is provided with a sleeve 3.
[0022] The top of the card strip 7 is chamfered and has a V-shaped cross-section, while the card seat 2 has a U-shaped cross-section.
[0023] When in use, the exposed parts of the square copper contact 1 and the O-type copper contact 6 are easy to distinguish, and the sheaths a5 and b9 are also different in shape. In restricted installation scenarios, there will be no confusion. The sheaths a5 and b9 are connected in the middle, which not only installs the wire harness and fixes the connection, but also plays a role in flame retardancy, making it safer and more reliable.
