Description

Technical Field

[0001] This utility model relates to the field of wire harness connector technology, and in particular to a wire harness connector for power distribution control equipment. Background Technology

[0002] Connectors, also known as plugs and sockets, are components that electronic engineers frequently encounter. They are mainly used to connect two or more active devices to achieve the transmission of current or signals. In power distribution cabinets, electrical components such as incoming power supplies, outgoing circuits, circuit breakers, and contactors need to be connected. Wire harness connectors ensure stable current transmission and prevent overheating, arcing, or even malfunctions caused by poor contact.

[0003] Currently, wire harness connectors in power distribution control equipment generally use a socket and plug snap-fit ​​method to achieve electrical connection. However, the existing snap-fit ​​structure has obvious drawbacks: the snap-fit ​​structure, with its simple snap-fit ​​design, is easy to quickly plug and unplug, but when subjected to external force, the connection is prone to separation, causing the socket and plug to loosen or even break, seriously threatening the stability of circuit operation; the snap-fit ​​structure can ensure a stable connection, but its separation requires precise pressing of the small snap-fit ​​mechanism, which not only requires high operational precision but also requires a certain amount of external force. In scenarios with a large number of connectors in the power distribution cabinet, frequent operation can easily cause hand fatigue and pain. In addition, regardless of the snap-fit ​​structure, when the data cable is subjected to external force, it will affect the connection with the plug, further increasing the risk of connection failure. Based on the above problems, this application proposes a wire harness connector for power distribution control equipment. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wire harness connector for power distribution control equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a wire harness connector for power distribution control equipment, including a socket and a plug, the plug being pluggable into the right end of the socket, with slots provided at the top and bottom of the right end of the socket, and snap-fit ​​plates fixedly installed in both slots, and U-shaped pluggable plates fixedly installed at the top and bottom of the left side of the plug, the two pluggable plates being inserted into the two slots at the right end of the socket and engaging with the corresponding snap-fit ​​plates, a fixing ring being fixedly installed on the outer wall of the socket, and a rotating ring being rotatably installed inside the fixing ring and fitted onto the socket, with two slots on both sides of the rotating ring's sidewall, a fixing tube being installed at the right end of the plug, and a data cable connected to the plug being inserted into the fixing tube, the right end of the fixing tube being fitted with an anti-pull component.

[0006] Optionally, the right side of the rotating ring is fitted onto the connection between the socket and the plug, and the positions of the two slots on the rotating ring are offset from the positions of the two plate slots on the right end of the socket. The rotating ring can be rotated at an angle greater than 30° to align the positions of the two slots on its side wall with the positions of the two plate slots on the right end of the socket. Grooves are provided at the top and bottom of the inner wall of the rotating ring, and limit blocks are provided in the two grooves. A first spring is fixedly connected between the two limit blocks and the corresponding grooves. Limit slots are provided at the top and bottom of the outer wall of the socket. The end of the two limit blocks that extends out of the groove is spherical, and the spherical ends of the two limit blocks can be respectively engaged in the two limit slots on the outer wall of the socket.

[0007] Optionally, the snap-fit ​​plate is made of deformable plastic material. The outer wall of the snap-fit ​​plate is flush with the outer wall of the socket. The inner wall of the snap-fit ​​plate has equally spaced slots, and the bottom of the inner wall of the snap-fit ​​plate has a snap block that matches the slots.

[0008] Optionally, fixing blocks are installed on both sides of the inner wall of the fixing ring, and semi-circular positioning rods are fixedly installed between the top and bottom of the two fixing blocks. Slider blocks are fixedly installed at the top and bottom of the left end of the rotating ring. The two sliders are slidably sleeved in the middle position of the two positioning rods, and second springs are sleeved on the two positioning rods at both ends of the sliders.

[0009] Optionally, the anti-pull component includes a sleeve, a third spring, and a threaded ring. The sleeve is movably fitted onto the right end of the fixed tube, and the right end of the sleeve has an X-shaped slit. The third spring is fitted onto the fixed tube, and the two ends of the third spring are respectively fixedly connected to the left end of the sleeve and the right end of the plug. The diameter of the opening at the right end of the sleeve is adapted to the data cable, and four sets of rubber pads are evenly and fixedly installed on the inner wall of the opening at the right end of the sleeve. The threaded ring is threaded onto the sleeve.

[0010] Optionally, the right end of the socket is provided with an annular sealing groove, and the left end of the plug is fixedly installed with a sealing ring that matches the sealing groove, and the sealing ring is tightened and inserted into the sealing groove.

[0011] The beneficial effects of this utility model are:

[0012] The plug is inserted into the slot on the left side of the socket via a connector plate on the right end. The connector plate deforms by pressing the locking plate. When the locking block on the connector plate engages with the locking slot on the locking plate, the connector plate is fully embedded in the slot. The inner wall of the rotating ring on the socket fits tightly against the outer wall of the locking plate, thus the locking plate keeps the connector plate in the slot and prevents it from detaching. To separate the socket and plug, the rotating ring is rotated to align the groove on its side wall with the slot on the socket. Then, by moving the plug, the connector plate can press the locking plate and detach it from the slot. The rotating ring not only increases the stability of the engagement between the locking plate and the connector plate, but its right end, located at the connection between the socket and the plug, also protects the connection. Compared to common connectors, this design offers higher connection stability, and separating the socket and plug only requires rotating the rotating ring, eliminating the need for pressing with fingers.

[0013] When the rotating ring rotates, the two sliders at the left end of the rotating ring slide on the two positioning rods inside the fixed ring. The sliding of the sliders pulls and compresses the second springs on both sides. The limiting block in the groove of the inner wall of the rotating ring will disengage from the limiting groove on the outer wall of the socket. After the socket and plug are connected or disconnected, the rotating ring is released. Under the elastic force of the second spring, the rotating ring can be reset, so that the inner wall of the rotating ring fits against the outer wall of the snap-fit ​​plate.

[0014] The anti-pull component protects the connection between the data cable and the plug. The plug has a spare data cable inside. By twisting the threaded ring, it moves to the right on the sleeve. The compression of the threaded ring ensures that the rubber pad on the inner wall of the right end of the sleeve makes full contact with the data cable, forming a stable friction fixation. When the data cable is pulled, it drives the sleeve to move to the right on the fixed tube. This rightward movement stretches the third spring. The elastic deformation of the third spring effectively buffers the pulling force, preventing external force from directly acting on the connection between the data cable and the plug. This protects the vulnerable connection point and significantly improves the durability and reliability of the wire harness connector. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please see Figures 1-8 This utility model provides a technical solution: a wire harness connector for a power distribution control device, including a socket 1 and a plug 2. The plug 2 can be inserted into the right end of the socket 1. Slots 5 are provided at the top and bottom of the right end of the socket 1, and snap-fit ​​plates 6 are fixedly installed in both slots 5. U-shaped insertion plates 7 are fixedly installed at the top and bottom of the left side of the plug 2. The two insertion plates 7 can be inserted into the two slots 5 at the right end of the socket 1 and engage with the corresponding snap-fit ​​plates 6. A fixing ring 8 is fixedly installed on the outer wall of the socket 1. A rotating ring 9 is rotatably installed inside the ring 8 and sleeved on the socket 1. Two slots 10 are opened on both sides of the side wall of the rotating ring 9. A fixing tube 18 is installed on the right end of the plug 2. A data cable 19 connected to the plug 2 is inserted into the fixing tube 18. An anti-pull component is sleeved on the right end of the fixing tube 18. The rotating ring 9 can constrain the snap-fit ​​plate 6 after it is engaged, so that the snap-fit ​​plate 6 can be stably engaged with the plug plate 7. The anti-pull component on the right end of the plug 2 can prevent external force from directly acting on the connection between the data cable 19 and the plug 2.

[0027] like Figure 1 , Figure 2 and Figure 7As shown, the right side of the rotating ring 9 is fitted at the connection between the socket 1 and the plug 2, and the positions of the two slots 10 on the rotating ring 9 are offset from the positions of the two plate slots 5 on the right end of the socket 1. The rotating ring 9 can be rotated at an angle greater than 30° so that the positions of the two slots 10 on its side wall are aligned with the positions of the two plate slots 5 on the right end of the socket 1. Grooves are provided at the top and bottom of the inner wall of the rotating ring 9, and limit blocks 11 are provided in the two grooves. A first spring 12 is fixedly connected between the two limit blocks 11 and the corresponding grooves. Limit grooves 13 are provided at the top and bottom of the outer wall of the socket 1. The end of the two limit blocks 11 that extends out of the groove is set as a ball, and the ball end of the two limit blocks 11 can be respectively engaged in the two limit grooves 13 on the outer wall of the socket 1.

[0028] The inner wall of the rotating ring 9 is tightly fitted to the outer wall of the snap-fit ​​plate 6. The snap-fit ​​plate 6 cannot deform due to the constraint of the rotating ring 9. Therefore, the plug plate 7 cannot detach from the slot 5 due to the constraint of the snap-fit ​​plate 6. When separating the socket 1 and the plug 2, the groove 10 on the side wall of the rotating ring 9 is aligned with the slot 5 on the socket 1 by rotating the rotating ring 9. At this time, the plug 2 is pulled, and the plug plate 7 can press the snap-fit ​​plate 6 in the same way, so that it can detach from the slot 5 without external force, thereby realizing the separation of the socket 1 and the plug 2.

[0029] By engaging the limiting block 11 with the limiting groove 13, the angle of the rotating ring 9 can be positioned so that the rotating ring 9 can be in a position that squeezes and constrains the snap-fit ​​plate 6, and is not prone to angular rotation.

[0030] like Figure 3 and Figure 4 As shown, the snap-fit ​​plate 6 is made of deformable plastic. The outer wall of the snap-fit ​​plate 6 is flush with the outer wall of the socket 1. The inner wall of the snap-fit ​​plate 6 has equally spaced slots. The bottom of the inner wall of the plug plate 7 has a locking block that matches the slot. The plug plate 7 at the right end of the plug 2 is inserted into the slot 5 at the left end of the socket 1. The plug plate 7 deforms by pressing the snap-fit ​​plate 6. When the locking block on the plug plate 7 and the slot on the snap-fit ​​plate 6 engage with each other, the plug plate 7 can be completely embedded in the slot 5.

[0031] like Figure 2 and Figure 8As shown, fixing blocks 15 are installed on both sides of the inner wall of the fixing ring 8. Semi-circular positioning rods 16 are fixedly installed between the top and bottom of the two fixing blocks 15. Slider blocks 14 are fixedly installed at the top and bottom of the left end of the rotating ring 9. The two sliders 14 are slidably sleeved in the middle position of the two positioning rods 16. Second springs 17 are sleeved on the two positioning rods 16 and at both ends of the sliders 14. When the rotating ring 9 rotates, the two sliders 14 on the left end slide on the two positioning rods 16 in the fixing ring 8. The sliding of the sliders 14 pulls and compresses the second springs 17 on both sides. After the socket 2 and plug 1 are connected or disconnected, the rotating ring 9 is released. Under the elastic force of the second springs 17, the rotating ring 9 can be reset, so that the inner wall of the rotating ring 9 fits against the outer wall of the snap-fit ​​plate 6.

[0032] like Figure 5 and Figure 6 As shown, the anti-pull assembly includes a sleeve 20, a third spring 21, and a threaded ring 22. The sleeve 20 is movably fitted onto the right end of the fixed tube 18, and an X-shaped slit is opened at the right end of the sleeve 20. The third spring 21 is fitted onto the fixed tube 18, and its two ends are respectively fixedly connected to the left end of the sleeve 20 and the right end of the plug 2. The diameter of the opening at the right end of the sleeve 20 is adapted to the data cable 19, and four sets of rubber pads 23 are evenly and fixedly installed on the inner wall of the opening at the right end of the sleeve 20. The ring 22 is threaded onto the sleeve 20. The anti-pull component provides enhanced protection for the connection between the data cable 19 and the plug 2. When the data cable 19 is subjected to external tension, the tension is transmitted to the sleeve 20 through the data cable 19. This causes the sleeve 20 to slide to the right along the fixed tube 18 and stretch the third spring 21. The elastic deformation of the third spring 21 absorbs the tension energy, preventing the instantaneous tension from acting directly on the welding or crimping parts of the data cable 19 and the plug 2, thereby effectively protecting the connection from external damage.

[0033] like Figure 3 and Figure 4 As shown, the right end of the socket 1 is provided with an annular sealing groove 3, and the left end of the plug 2 is fixedly installed with a sealing ring 4 that matches the sealing groove 3. The sealing ring 4 is tightened and inserted into the sealing groove 3. Through the insertion of the sealing ring 4 into the sealing groove 3, the connection between the socket 1 and the plug 2 can be sealed and waterproofed.

[0034] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
