Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to an adjustable wire harness installation connector tail clip isolator. Background Art

[0002] At present, in the manufacturing of wire harnesses, connectors have become a convenient, fast and highly reliable component widely used in the aerospace field. After the pins and sockets of the connector are crimped or welded, the wire harness is fixed by the tail clip. However, when the wire harness number is large, the wire harness at the tail clip is affected by the pressure of the tail clip, and the center of the wire harness section at the tail clip is not coaxial with the center of the wire harness at the pin and socket, which may cause the pin and socket in the connector to be tilted due to force, further leading to problems such as pin withdrawal when the plug and socket are plugged in.

[0003] In most cases, existing connector harnesses are simply fixed with tail clips during installation. When the pins and sockets in the connector are tilted due to force, various flame-retardant insulating tapes and other auxiliary materials are used to thicken the wire diameter in a winding manner so that the center of the cross-section of the harness at the tail clip is coaxial with the center of the harness at the pin and socket, and the harness is not subjected to stress in other directions. There are no standard components to deal with the above problems, so an adjustable harness installation connector tail clip isolator is needed to meet people's needs. Utility Model Content

[0012] The beneficial effects of the utility model are:

[0013] In the utility model, the space between the first positioning groove and the second positioning groove is adjusted and changed through the rotational connection between the first isolator and the second isolator, so that the isolator can be adapted to wire harnesses of different specifications, thereby making the center of the cross section of the wire harness in the groove coaxial with the center of the cross section of the wire harness at the pin hole, and the wire harness is not subjected to stress in other directions, preventing the connector contact from being tilted due to force.

[0014] In the utility model, the spline shaft is switched back and forth in the first isolator and the second isolator, so that the first isolator and the second isolator are separated and connected. When the knob is pressed, the connecting shaft pushes the spline shaft to separate from the first isolator, the spring is compressed, and the knob is turned, so that the connecting shaft drives the spline shaft to rotate, thereby driving the second isolator to rotate for angle adjustment. When the pressing stops, the elastic force of the spring causes the spline shaft to move upward, and the spline shaft moves partly from the second isolator to the first isolator, thereby realizing the connection between the second isolator and the first isolator, and then realizing the locking after adjustment, thereby improving the stability of wire harnesses of different specifications after locking.

[0024] Through the rotational connection between the first isolator 3 and the second isolator 4, the space between the first positioning groove 10 and the second positioning groove 11 is adjusted and changed, so that the isolator can be adapted to wiring harnesses of different specifications, so that the center of the cross-section of the wiring harness in the groove is coaxial with the center of the cross-section of the wiring harness at the pin hole, and the wiring harness is not subjected to stress in other directions, preventing the connector contact from being tilted by force. The spline shaft 7 switches back and forth in the first isolator 3 and the second isolator 4, so that the first isolator 3 and the second isolator 4 are separated and connected. When the knob 9 is pressed, the connecting shaft 8 pushes the spline shaft 7 to separate from the first isolator 3, the spring 6 is compressed, and the knob 9 is turned, so that the connecting shaft 8 drives the spline shaft 7 to rotate, thereby driving the second isolator 4 to rotate for angle adjustment. When the pressing stops, the elastic force of the spring 6 causes the spline shaft 7 to move upward, and the spline shaft 7 moves partly from the second isolator 4 to the first isolator 3, thereby realizing the connection between the second isolator 4 and the first isolator 3, and then realizing the adjusted locking, thereby improving the stability of wiring harnesses of different specifications after locking.

[0027] Specifically, in the present embodiment, a second spline groove 14 is provided on the second isolator 4. The second spline groove 14 has the same specifications as the first spline groove 13, and its depth is greater than that of the first spline groove 13. The lower part of the spline shaft 7 is adapted in the second spline groove 14, providing sufficient space for the downward pressing of the spline shaft 7, thereby realizing complete separation of the spline shaft 7 from the first spline groove 13.

[0028] Specifically, in this embodiment, a spring groove 15 is opened on the bottom end of the second spline groove 14, and one end of the spring 6 is connected to the spring groove 15 to provide space for compression of the spring 6, so that the depth of the second spline groove 14 can provide movement space for the spline shaft 7.
