Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial wire harness technology, specifically to an industrial wire harness that is convenient for inspection and maintenance. Background Technology
[0002] With the continuous improvement of automation and intelligence in modern industry, industrial equipment places higher demands on the reliability and ease of maintenance of electrical connections. As a key component in industrial equipment for transmitting electrical signals and power, the performance of industrial wire harnesses directly affects the stable operation and safety of the entire system. Especially in complex industrial environments, wire harnesses not only need to have excellent electrical connection performance, but also need to facilitate on-site plugging and unplugging operations and subsequent inspection and maintenance to meet the needs of equipment maintenance and upgrades.
[0003] Most existing industrial wire harnesses use a direct-plug connection structure, which relies primarily on friction between the plugs for connection and fixation. While this design is simple and has low manufacturing costs, it has several drawbacks. First, friction-based connections are prone to loosening due to vibration, temperature changes, or external forces during long-term use, leading to poor contact or even disconnection, affecting the normal operation of the equipment. Second, the lack of effective guidance and locking mechanisms during insertion and removal makes misalignment or incomplete connection more likely, increasing maintenance difficulty and the risk of failure. Furthermore, friction-based connections lack precise control over insertion and removal forces, often requiring considerable force during operation, increasing the workload of maintenance personnel and hindering frequent disassembly and assembly.
[0004] Therefore, existing direct-plug industrial wire harnesses still have significant shortcomings in ensuring connection stability and ease of operation. There is an urgent need for an industrial wire harness connection solution that is structurally sound, reliably locked, and easy to inspect and maintain, in order to improve the overall performance and user experience of industrial wire harnesses.

The center of the plug groove is provided with connection male heads that are adapted to the connection holes on both sides, and the connection male heads and connection female heads are electrically connected.
[0011] As a preferred technical solution of this utility model, two semi-circular guide protrusions are provided on the upper and lower groove walls inside the insertion groove, and two guide grooves are provided on the front and rear sides of the insertion protrusion, with the guide protrusions and guide grooves being compatible.
[0012] As a preferred technical solution of this utility model, a number of anti-slip grooves are evenly provided on the outer side of the cap.
[0013] As a preferred embodiment of this utility model, wires are installed on the end faces of the socket and connector that are away from the plug-in end face.
[0014] Compared with the prior art, this utility model provides an industrial wire harness that is convenient for inspection and maintenance, and has the following beneficial effects:
[0015] This industrial wire harness significantly improves the ease and convenience of insertion and removal operations through a rationally designed and compact inspection and maintenance mechanism between the connector and the plug. The precise fit between the guide protrusion and guide groove effectively prevents misalignment and incomplete insertion during the connection process, ensuring accuracy and smoothness in every connection. The locking protrusion and locking groove, combined with the internal rotating shaft and screw cap threaded locking structure, achieve a secure lock after insertion, preventing loosening or detachment due to vibration or external force, greatly improving the stability and safety of the connection.
[0016] Furthermore, the anti-slip groove design on the screw cap improves the user's grip during operation, making the insertion and removal actions more effortless and precise, conforming to ergonomics, and reducing operator fatigue and the risk of misoperation. The snap-fit protrusion ring stably fixes the rotating shaft, ensuring the reliable operation of the locking mechanism, further enhancing the durability and service life of the entire connection structure.
[0017] In summary, this industrial wire harness design balances structural rationality with ease of operation. Multiple guiding and locking mechanisms ensure accurate and secure connections during insertion and removal, significantly improving connection stability and safety. Its user-friendly anti-slip cap design and reliable internal locking components make insertion and removal operations easier and smoother, greatly reducing the operational difficulty and workload for maintenance personnel. This wire harness structure not only meets the high reliability and stability requirements of industrial environments but also greatly facilitates subsequent inspection and maintenance, improving the overall equipment's operating efficiency and service life, demonstrating broad application prospects and promotional value.

[0031] Please see Figure 1-5 An industrial wire harness that is easy to inspect and maintain is characterized by a structure designed between the plug socket 1 and the plug connector 2 to facilitate inspection and maintenance, ensuring reliable and detachable connection, and facilitating subsequent maintenance and repair.
[0032] The connector 1 is provided with a connector groove 11 for receiving the connector protrusion 21 of the connector 2. A locking protrusion 13 is provided at the center of the connector groove 11, and a threaded locking hole 14 is provided at the center of the locking protrusion 13 for cooperating with the locking component 25 inside the connector 2 to ensure a firm connection.
[0033] The plug protrusion 21 on the plug end face of the plug connector 2 has a locking groove 24 in the center, which cooperates with the locking protrusion 13 on the plug seat 1 to ensure the firmness and safety of the plug connection.
[0034] A locking component 25 is installed inside the connector 2, which is rotatably mounted inside the connector 2 via a rotating shaft 252. The front end of the rotating shaft 252 is located inside the locking groove 24 and engages with the thread in the threaded locking hole 14. The rear end of the rotating shaft 252 extends out of the connector 2 and mates with the rotating cap 251. The rotating cap 251 is provided with an anti-slip groove 2511 to facilitate a firm grip by the user during rotation.
[0035] A snap-fit protrusion ring 253 is provided in the middle section of the rotating shaft 252. This protrusion ring is used to rotate and snap into the inside of the plug 2 to ensure the stability and reliability of the rotating shaft.
[0036] The plug protrusion 21 has connection holes 22 on both sides of the plug end face, and the holes are equipped with connection females 23. In the plug groove 11, there are also connection males 12 on both sides of the plug groove. These males 12 are electrically connected to the females 23 to realize the electrical connection between the plug socket 1 and the plug 2.
[0037] Two semi-circular guide protrusions 15 are respectively provided on the upper and lower groove walls inside the insertion groove 11, and two guide grooves 26 are also provided on the front and rear sides of the insertion protrusion 21. These guide protrusions 15 and guide grooves 26 cooperate with each other to ensure that the insertion protrusion 21 can be smoothly inserted into the insertion groove 11 during the insertion process, and to prevent incomplete insertion or misalignment.
[0038] Wires are installed on the end faces of both the socket 1 and the connector 2 away from the plug end face to ensure the smoothness and stability of the electrical connection.
[0039] Working principle
[0040] First, align the insertion protrusion 21 on the connector 2 with the insertion groove 11 on the connector 1, ensuring that the guide groove 26 on the insertion protrusion 21 and the semi-circular guide protrusion 15 in the insertion groove 11 cooperate to avoid misalignment or incomplete insertion. Then, smoothly insert the front end of the insertion protrusion 21 into the insertion groove 11, so that the connecting female head 23 inside the connector 2 contacts the front ends of the connecting male heads 12 on both sides of the connector 1. Next, rotate the cap 251 at the rear end of the connector 2. The anti-slip groove 2511 on the cap 251 facilitates gripping, driving the internal rotating shaft 252 to rotate. This causes the locking thread 254 at the front end of the rotating shaft 252 to screw into the threaded locking hole 14, thereby tightening and closing the remaining gap between the connector 2 and the connector 1 through a spiral screwing motion, achieving a complete insertion operation. During disassembly, rotate the cap 251 in the opposite direction, and then use a spiral lifting method to separate the closed end face between the connector 2 and the socket 1. Then, the socket 1 and the connector 2 can be easily pulled apart. The entire connection and disassembly process is reasonably structured and easy to operate, ensuring the reliability of industrial wire harness connections and facilitating subsequent inspection and maintenance.
