Description

Technical Field

[0001] This utility model belongs to the field of wire harness connection technology, and more specifically, it relates to a quick-operation wire harness connector connection and installation device. Background Technology

[0002] As the core carrier for transmitting electrical energy and control signals in an electrical system, the reliability of the wire harness connection directly determines the operational stability and safety of the entire electrical system. As a key component for realizing detachable connections between wire harnesses and electrical components, and between wire harnesses themselves, the quality of the wire harness connector connection is the core link in ensuring the transmission performance of the wire harness. Whether the connector connection is firm and whether the contact is good can affect the accuracy of signal transmission and the efficiency of power transmission.

[0003] Based on existing technology, it has been found that the design of existing wire harness connectors has some shortcomings: First, most existing wire harness connectors use a common plug-in structure. Although this plug-in structure is convenient for connection and installation, its pull-out resistance is poor. In daily use, the wire harness will inevitably be subjected to external forces such as pulling, vibration or impact. At this time, the plug-in structure is prone to loosening or even completely detaching, which will directly lead to the interruption of the wire harness connection. Secondly, the connection stability of existing wire harness connectors tends to decrease over time. Under long-term environmental influences, the contact pressure between the connector and the pin or socket will gradually decrease, leading to loose connections. This increases contact resistance, causing power loss and abnormal signal transmission. Solving this problem requires regular manual inspection and maintenance, which increases labor costs and workload. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model relates to a quick-operation wire harness connector connection and installation device. This addresses the issue that most existing wire harness connectors use a common plug-in structure. While this structure facilitates connection and installation, its pull-out resistance is poor. During daily use, wire harnesses inevitably experience external pulling, vibration, or impact, which can easily cause the plug-in structure to loosen or even completely detach, directly leading to interruption of the wire harness connection. Furthermore, the connection stability of the wire harness connector tends to decrease over time. Under long-term environmental influences, the contact pressure between the connector and the pin / socket gradually decreases, leading to loosening of the connection. This increases contact resistance, causing power loss and abnormal signal transmission. Solving this problem requires regular manual inspection and maintenance, which increases labor costs and workload.

[0005] In a first aspect, this utility model provides a quick-operation wire harness connector connection and installation device, achieved by the following specific technical means: A quick-operation wire harness connector connection and installation device, comprising: Housing A; Housing A has a square structure, and the front side of Housing A is joined with Housing B; The mounting groove inside Housing A is threadedly connected to the shaft, and the front side of the shaft is inserted into the mating groove inside Housing B, and the fixing block at the outer end of the shaft is inserted into the connecting groove in the mating groove. The fixing block is located at the end of the connecting groove. A connector A is inserted inside Housing A, and the connector A passes through the shaft. A connector B is inserted inside Housing B, and the connector A passes through the mating groove.

[0006] Furthermore, a mounting groove is provided in the middle of housing A, and threads are provided inside the mounting groove. Slots are provided on both sides of the outer side of housing A.

[0007] Furthermore, a mating groove is provided in the middle of the interior of the shell B, and L-shaped connecting grooves are provided on both sides of the inner wall of the mating groove.

[0008] Furthermore, side grooves are provided on both sides of the housing B. A telescopic block is slidably installed inside the side groove through a spring. The end of the telescopic block can extend out from inside the side groove, and the spherical structure at the end of the telescopic block engages with the slot.

[0009] Furthermore, movable grooves are provided inside the housings A and B. The movable grooves in housings A and B are respectively penetrated by connectors A and B, and a top ring is slidably installed inside the movable groove by means of a spring. The top ring extends from both sides of the movable groove.

[0010] Furthermore, a circular through groove is provided inside the shaft, and fixing blocks are symmetrically arranged at both ends of the front side of the shaft.

[0011] Furthermore, connector A and connector B are inserted into each other, and a fixing ring is fixedly installed on the outer end of connector A and connector B. The fixing ring is located in the movable groove and is in contact with the top ring.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In this device, a shaft is threaded onto housing A, and telescopic blocks are installed at both ends of housing B. When inserting the wire harness connector, the shaft is inserted into the mating groove and rotated 90°. The fixing block at its outer end can then engage deep into the L-shaped connecting groove, forming a limit along the axial direction of the shaft. At the same time, the telescopic block in the side groove of housing B, under the action of the spring, has its spherical end engaged in the slot of housing A, restricting the relative rotation between housing A and housing B. This double locking structure can effectively fix housing A and housing B, thereby ensuring the stable connection of connector A and connector B, effectively resisting external pulling and vibration impact, avoiding wire harness connection interruption, and significantly improving the fixing effect of wire harness connection.

[0013] 2. In this device, a top ring is movably installed in the movable grooves inside housing A and housing B. Under the action of a spring, the top ring continuously abuts against the fixed rings of connector A and connector B, providing a constant clamping force to the mating surfaces of the connectors and ensuring tight contact. Even if the connectors become loose under long-term vibration, temperature cycling, or slight external force, the top ring can push the fixed rings with the springs to automatically reset the connectors and keep them in a tight-fitting state. This automatic compensation clamping structure does not require manual operation, which not only saves labor costs but also achieves long-term stability of the wire harness connector connection.
