[0029] The following will describe in detail the specific implementation of the present utility model with reference to the accompanying drawings. It should be understood that the specific implementation described herein is only for the purpose of illustration and explanation of the present utility model, and is not intended to limit the present utility model.

[0030] It should be noted that the "first", "second" and similar terms used in the present utility model do not indicate any order, quantity or importance, but are only used to distinguish different parts. Words such as "including" or "comprising" mean that the elements before the word cover the elements listed after the word, and do not exclude the possibility of also covering other elements.

[0031] Combined with Figure 1 As shown, a connector provided by an embodiment of the present utility model includes a panel housing 2, a connector housing 1 sleeved on the panel housing 2, and a fixing bracket for fixing a plastic connector. The fixing bracket includes a first fixing bracket 3 and a second fixing bracket 4 corresponding to each other in the vertical direction. The first fixing bracket 3 is arranged inside the connector housing 1 and is used to fix the wire end of the plastic connector. The second fixing bracket 4 is arranged inside the panel housing 2 and is used to fix the board end of the plastic connector.

[0032] The panel housing 2 cooperates with the connector housing 1 to jointly form the external structure of the connector.

[0033] As a key component for connecting circuits or signals, the wire end and board end of the plastic connector correspond to each other in the vertical direction. Through the precise design and installation of the fixing bracket, seamless docking and stable connection between the two are achieved. This design not only improves the overall performance of the connector but also simplifies the installation and disassembly process.

[0034] In some embodiments, the fixing bracket can be designed as a modular component, providing modules of various sizes and shapes for selection to adapt to different specifications and types of plastic connectors, thereby improving the versatility and flexibility of the product.

[0035] In some embodiments, the first fixing bracket 3 is detachably arranged inside the connector housing 1, and the second fixing bracket 4 is detachably arranged inside the panel housing 2.

[0036] In some embodiments, the panel housing 2, connector housing 1, and fixing bracket can be made of materials with certain strength and stability, such as metal materials. Preferably, the surface of the connector can be subjected to anti-corrosion treatment, such as using an anti-rust coating or plating, etc., to ensure the service life and performance stability of the connector in a humid environment.

[0037] In some embodiments, the connector housing 1 is provided with guiding features, and the panel housing 2 is provided with guiding mating features that cooperate with the guiding features. The use of the guiding features and guiding mating features ensures the precise alignment of the connector housing 1 and the panel housing 2 during the assembly process, preventing misalignment or offset.

[0038] It can be understood that the guiding features and guiding mating features can be any suitable structures known to those skilled in the art, as long as it is ensured that the guiding mating features can closely cooperate with the guiding features or form an effective sealing interface after assembly to prevent the intrusion of external substances such as water and dust.

[0039] Furthermore, the connector housing 1 and the panel housing 2 are set as a detachable modular structure, enabling components such as the guiding features and guiding mating features to be replaced or upgraded individually.

[0040] Combined Figure 1 and Figure 2 As shown, a control rod 11 and a linear groove 12 penetrating inside and outside are provided on the connector housing 1 of the present utility model. The control rod 11 is rotatably mounted on the connector housing 1, and a fixing member 21 that can be inserted into the linear groove 12 is provided on the panel housing 2. When the control rod 11 rotates, the fixing member 21 cooperates with the control rod 11 to lock the connector housing 1 and the panel housing 2 in a mutually aligned state together.

[0041] Specifically, when the connector housing 1 is sleeved on the panel housing 2, the two are in a position close to each other but not completely locked, a rotatable control rod 11 is installed on the connector housing 1, and a linear groove 12 is designed at the corresponding position of the control rod 11 to penetrate the connector housing 1, and the linear groove 12 extends to the bottom edge of the connector housing 1. A fixing member 21 matching the linear groove 12 is designed on the panel housing 2, and the fixing member 21 can be a slider, a pin or other forms of mechanical parts, and its shape and size allow it to smoothly enter the linear groove 12. When the fixing member 21 enters the linear groove 12, the control rod 11 begins to rotate. The rotation design of the control rod 11 enables it to affect the fixing member 21 in the linear groove 12 in a way, which can be by setting other mechanical mechanisms on the control rod 11, thereby driving the fixing member 21 to move in the linear groove 12 along the guide path of the linear groove 12 in the linear groove 12 in a direction away from the bottom edge of the connector housing 1, thereby achieving a secure locking of the connector housing 1 and the panel housing 2. It can be understood that this locking position is usually determined by the rotation angle of the control rod 11 and the specific design of the length of the linear groove 12.

[0042] In some embodiments, multiple corresponding control rods 11, linear grooves 12 and fixing members 21 may be provided, and multiple control rods 11 and multiple linear grooves 12 are provided on different sides of the connector housing 1, and multiple fixing members 21 are provided on different sides of the panel housing 2.

[0043] The connector provided by the utility model makes the connection between the connector housing 1 and the panel housing 2 flexible and easy to operate by designing the matching mechanism of the control rod 11, the linear groove 12 and the fixing member 21. The rotation of the control rod 11 can directly drive the movement of the fixing member 21 in the linear groove 12, so that the connector housing 1 and the panel housing 2 are automatically locked or unlocked when the control rod 11 is rotated, which greatly simplifies the assembly and disassembly process and improves work efficiency. The fixing frame provides stable support and positioning for the plastic connector, and indirectly promotes the rapid disassembly and assembly between the connector housing 1 and the panel housing 2. When the control rod 11 rotates and unlocks the fixing member 21, since the fixing frame has ensured the stable position of the plastic connector, the user can more easily separate or reassemble the connector housing 1 from the panel housing 2.

[0044] In some embodiments, in combination Figure 1 , Figure 4 as well as Figure 5 As shown, a first mounting groove 13 is arranged around the inner wall at the connection between the connector housing 1 and the first fixing frame 3, and a first sealing gasket 5 matching the size thereof is arranged in the first mounting groove 13. A second mounting groove 22 is arranged around the bottom of the panel housing 2 near the edge, and a second sealing gasket 6 matching the size thereof is arranged in the second mounting groove 22.

[0045] It is understandable that the material of the gasket can be selected according to the changes in the usage environment of the connector, such as high-temperature resistant or corrosion-resistant materials.

[0046] In some embodiments, a special adhesive is used to fix the gasket to the installation groove to enhance the stability of the gasket and prevent displacement or detachment during use.

[0047] In some embodiments, a mechanical locking structure, such as a snap or a screw, can also be set to firmly fix the gasket in the installation groove, improving the reliability and durability of the seal.

[0048] Furthermore, a guiding structure, such as an inclined plane or a chamfer, is provided at the edge of the installation groove to facilitate the smooth installation of the gasket and reduce friction and damage during installation.

[0049] In this embodiment, when the control lever 11 is pulled to close and lock the connector housing 1 and the panel housing 2, the gasket is squeezed to play a role in waterproofing and dustproofing. By preventing the intrusion of external contaminants, the gasket effectively extends the service life of the internal components of the connector and reduces the maintenance and replacement costs caused by failures such as corrosion and short circuits. In addition, the elastic buffering characteristic of the gasket can absorb the energy generated when the connector is subjected to vibration or impact, reducing the influence of these external factors on the internal structure of the connector, thereby maintaining the stability and reliability of the connection. The tight fit of the gasket helps to prevent loosening between the connector housing 1 and the panel housing 2, especially after long-term use or multiple insertions and extractions, and still maintains a good connection state. The gasket can also reduce friction and wear during the insertion and extraction of the connector.

[0050] In some embodiments, as Figure 1 shown, a threaded hole for the cable to pass through for connecting with the plastic connector wire end is provided on the connector housing 1. A sealing ring 8 and a matching nut 9 are provided on the threaded hole, that is, the nut 9 is tightened to squeeze the sealing ring 8 to play a role in locking the wire harness and sealing and waterproofing.

[0051] It is understandable that the material of the sealing ring 8 can be selected according to the type of the cable and the working environment (such as temperature, humidity, chemical substances, etc.).

[0052] In some embodiments, a mechanism for quick locking and unlocking is provided on the nut 9, such as a spring-loaded quick-locking nut 9 or a rotary mechanism with lever assistance, to improve the installation and disassembly efficiency.

[0053] Furthermore, in order to reduce the wear of the cable, wear-resistant parts, such as plastic bushings or rubber gaskets, are added at the part where the cable contacts the threaded hole.

[0054] In some embodiments, combining Figure 4 andFigure 5 As shown, a guiding groove 14 is provided on the inner wall of the connector housing 1, and a guiding block 23 is provided on the panel housing 2 which is inserted into and cooperates with the guiding groove 14. The cooperation between the guiding groove 14 and the guiding block 23 enables the connector to move along a predetermined trajectory during the assembly process, avoiding misalignment or inclination, and playing a role in preventing incorrect insertion. In addition, after the guiding block 23 is inserted into the guiding groove 14, it not only plays a role in positioning and stabilizing, but also becomes a part of the reinforcing structure of the connector housing 1 due to its own structural characteristics. Similar to a reinforcing rib, when the connector is subjected to external forces, it can disperse and resist these forces, thereby enhancing the structural strength and rigidity of the entire connector.

[0055] In some embodiments, the guiding groove 14 can be provided with a straight groove or a multi-directional groove (such as an arc shape, a spiral shape, etc.) to adapt to panel housings 2 with different shapes and installation angles.

[0056] Preferably, specific shapes, sizes or marks are provided on the guiding groove 14 or the guiding block 23.

[0057] In some embodiments, there are multiple mutually cooperating guiding grooves 14 and guiding blocks 23. The multiple guiding grooves 14 and the multiple guiding blocks 23 are respectively evenly spaced on the connector housing 1 and the panel housing 2.

[0058] In some embodiments, in combination Figure 1 and Figure 6 As shown, a guiding screw 7 is provided between the connector housing 1 and the panel housing 2. The guiding screw 7 passes through the fixing frame and is respectively fixed at the corresponding positions of the connector housing 1 and the panel housing 2, ensuring the precise alignment and stable connection between the connector housing 1 and the panel housing 2, as well as between the first fixing frame 3 and the second fixing frame 4, reducing the error during the assembly process, and improving the accuracy and reliability of the connection.

[0059] Preferably, multiple guiding screws 7 are provided between the connector housing 1 and the panel housing 2 for multi-point fixing.

[0060] Preferably, the guiding screw 7 is set to be adjustable. By adjusting the tightening degree or length of the guiding screw 7, it can adapt to panel housings 2 with different thicknesses or sizes, improving the flexibility and adaptability of the connection.

[0061] In some embodiments, in combination Figure 7 As shown, the control rod 11 includes two rotating parts 111. The two rotating parts 111 are rotatably connected to the left and right side surfaces of the connector housing 1. When the control rod 11 includes two rotating parts 111, they can be operated simultaneously or separately to lock the connector housing 1 and the panel housing 2. The two rotating parts 111 may provide different locking forces or locking directions during the locking process, thereby enhancing the connection stability between the connector housing 1 and the panel housing 2.

[0062] Preferably, in order to prevent the rotating member 111 from rotating excessively or not reaching the proper position, a limiting mechanism is provided on the rotating member 111. The limiting mechanism can ensure that the rotating member 111 stops rotating when it reaches the predetermined position, thereby improving the accuracy and reliability of locking.

[0063] In some embodiments, the two rotating members 111 are arranged to rotate synchronously, that is, when one of the rotating members 111 is operated, the other rotating member 111 will also rotate simultaneously.

[0064] Specifically, an arc-shaped notch 113 penetrating the rotating member 111 is provided on the rotating member 111. A straight end 1131 extending along the vertical direction is provided at the bottom end of the arc-shaped notch 113, and the straight end 1131 corresponds to the straight groove 12.

[0065] In this embodiment, the arc-shaped notch 113 is semi-circular or of a similar shape, and its opening direction faces the straight end 1131 so as to cooperate with the fixing member 21 on the panel housing 2. When the connector housing 1 is guided and sleeved on the panel housing 2, when the control rod 11 rotates to a specific position, the fixing member 21 simultaneously enters the straight groove 12 and the straight end 1131 corresponding to the straight groove 12. When the control rod 11 continues to rotate, the fixing member 21 enters the arc-shaped notch, and the arc-shaped notch drives the fixing member 21 to continue moving upward along the straight groove 12. When the control rod 11 rotates to the final position, the fixing member 21 is completely locked in the straight groove 12, thereby realizing the tight connection between the connector housing 1 and the panel housing 2. When it is necessary to disassemble the connector housing 1 and the panel housing 2, only the control rod 11 needs to be rotated in the reverse direction.

[0066] Furthermore, the control rod 11 further includes a rotating handle 112. The two ends of the rotating handle 112 are respectively fixedly connected to the two rotating members 111. The design of the rotating handle 112 enables the user to drive the control rod 11 to rotate more easily.

[0067] It can be understood that the shape and structure of the rotating handle 112 can be any suitable shape and structure, and the material of the handle can be selected from soft materials with good grip feeling such as rubber and silica gel to increase the friction with the hand.

[0068] Furthermore, as Figure 3 shown, on one side of the connector housing 1 adjacent to the side surface where the rotating member 111 is installed, an inclined surface 15 inclined towards the inside of the connector housing 1 is provided to avoid the rotating handle 112. The setting of the inclined surface 15 provides sufficient avoidance space for the rotating handle 112 to prevent the handle from interfering with or colliding with other parts of the connector housing 1 when the control rod 11 is rotated.

[0069] It is understandable that the inclination angle of the inclined plane 15 can be adjusted according to actual needs. The junction of the inclined plane 15 and other parts of the connector housing 1 adopts a smooth transition structure to reduce stress concentration and wear caused by acute angles or mutations, and at the same time avoid sharp corners from scratching users.

[0070] In some embodiments, as Figure 6 shown, a plurality of first mounting grooves 31 for fixing the wire ends of the plastic connector are provided in the middle part of the first fixing frame 3, and second mounting grooves 32 for mounting the ground wire terminals are provided on the left and right sides of the first fixing frame 3; a plurality of third mounting grooves 41 for fixing the board ends of the plastic connector are provided in the middle part of the second fixing frame 4, and fourth mounting grooves 42 for mounting the ground wire terminals are provided on the left and right sides of the second fixing frame 4.

[0071] The first mounting groove 31 is located in the middle part of the first fixing frame 3 and is used to fix the wire ends of the plastic connector; while the third mounting groove 41 is located in the middle part of the second fixing frame 4 and correspondingly fixes the board ends of the plastic connector. This ensures a stable connection of the connector in both horizontal and vertical directions. The mounting grooves are designed to be standardized, allowing for quick and accurate installation and fixation of the plastic connector without additional adjustment or calibration steps, thus improving production efficiency and assembly accuracy.

[0072] A plurality of first mounting grooves 31 and third mounting grooves 41 are respectively provided. The plurality of first mounting grooves 31 and the plurality of third mounting grooves 41 correspond one by one. The plastic connector can freely switch the mounting position and the number of PINs, and can install plastic connectors of different quantities, types and specifications according to actual needs, providing good flexibility and scalability to meet the requirements of different application scenarios.

[0073] The second mounting grooves 32 and the fourth mounting grooves 42 are respectively provided on the left and right sides of the first fixing frame 3 and the second fixing frame 4 for mounting the ground wire terminals, ensuring the stable fixation of the ground wire terminals and improving the reliability and safety of the electrical connection.

[0074] In summary, compared with the existing technology, the connector provided by the present utility model has the following beneficial effects:

[0075] First, through the assembly of multiple components to form an integral connector, the connection of the present utility model can effectively prevent misinsertion and the entry of external moisture, improving the stability and reliability of the product.

[0076] Second, the connector of the present utility model adopts a combined modular housing design, making docking and disassembly simple. Compared with traditional connectors, the connector of the present utility model does not require complex disassembly steps, saving time and labor costs.

[0077] III. The connector of the present utility model adopts a modular design and can assemble different components according to different requirements, providing a more flexible usage method.

[0078] As a new type of connector, the connector provided by the present utility model has the characteristics of waterproof, anti-misinsertion, quick disassembly, etc., can meet the market demand, and has broad market prospects and application prospects in the fields of electronic devices, communication devices, industrial devices, etc.

However, the present utility model is not limited thereto. Within the technical concept scope of the present utility model, various simple modifications can be made to the technical solutions of the present utility model, including combining each specific technical feature in any suitable way. To avoid unnecessary repetition, the present utility model will not separately describe various possible combination methods.
