[0017] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments. Example
[0020] Please see Figure 1 - Figure 4 The first embodiment of this utility model This embodiment provides an internally locking, pluggable, self-locking connector, including: Plug housing 7; Spring 8 is located at the bottom of the plug housing 7; Male rubber core 9 is located at the bottom of spring piece 8; Male needle core 10, which is located at the bottom of male adhesive core 9; Wire clip 11, which is located at the bottom of male pin core 10; Long nut 12, which is located at the bottom of wire clamp 11; The socket housing 6 is located on the left side of the long nut 12; The female core 5 is located on the top of the socket housing 6; The female needle core 4 is located on top of the female rubber core 5; The core fixing cover 3 is located on the top of the female needle core 4.
[0021] For example, the top of the core fixing cover 3 is provided with a beveled nut 2, and the top of the beveled nut 2 is provided with a hexagonal nut 1.
[0022] The assembly relationship between the plug and the socket is shown, with the upper and lower positions of components such as hexagonal nut 1, beveled nut 2, and rubber core fixing cover 3 marked, as well as the left and right mating relationship between long nut 12 and socket housing 6.
[0023] Highlight the fifth thread on the outside of the socket housing 6, as well as the mounting positions of the bevel nut 2 and the hexagonal nut 1, to illustrate the layout of the external locking structure.
[0024] The internal wire clamping groove of the wire clamp 11 is shown in detail, as well as its connection with the male pin core 10, illustrating the specific structure for fixing the wire.
[0025] Enlarged details of the connection between the female pin core 4 and the female rubber core 5 show how the female pin core is fixed to the top of the female rubber core and its relative position to the socket housing 6.
[0026] The nesting relationship between the male pin core 10 and the male adhesive core 9 is shown, as well as their installation status inside the wire clamp 11, demonstrating the layered design of the male terminal conductive structure.
[0027] For example, the top of the inner side of the long nut 12 is provided with a first thread, the outer side of the bottom of the spring piece 8 is provided with a second thread, and the three male rubber cores 9, the male needle core 10 and the wire clamp 11 are fixed in the long nut 12 by the two first threads and the second threads.
[0028] Furthermore, the snap-fit and nesting design The latches on both sides of the spring 8 engage with the socket of the plug housing 7, and when inserted into the socket, they cooperate with the locking groove inside the socket to form a double mechanical lock.
[0029] The male core 9 is set outside the male needle core 10, and both are located inside the wire clamp 11. The nested structure expands the wire connection space and improves contact stability.
[0030] For example, a third thread is provided on the top of the outer side of the socket housing 6, and a fourth thread is provided on the inner side of the core fixing cover 3. The two female cores 5 and the female pin core 4 are fixed to the inner side of the socket housing 6 by the threaded connection between the two third threads and the fourth threads.
[0031] Furthermore, threaded connection systems The first thread of the long nut 12 engages with the second thread of the spring 8, connecting and fixing the male core 9, male pin core 10, and wire clamp 11 in series to form the core conductive structure of the plug.
[0032] The third thread of the socket housing 6 is connected to the fourth thread of the core fixing cover 3 to fix the female core 5 and the female pin core 4, ensuring the stability of the female end structure.
[0033] The fifth thread on the socket housing 6 is used to install the bevel nut 2 and the hex nut 1, thereby achieving external locking of the entire socket.
[0034] For example, a fifth thread is provided on the outer side of the socket housing 6 and at the bottom of the third thread, and two bevel nuts 2 and hexagonal nuts 1 are fitted on the surface of the socket housing 6.
[0035] Furthermore, the wire connection: the wire clamp 11 clamps the wire, and the nested structure of the male rubber core 9 and the male pin core 10 increases the wire interface area, reduces contact resistance, and improves the stability of current transmission.
[0036] Structural fixation: The female core 5 and the female needle core 4 are connected to the fourth thread of the core fixing cover 3 through the third thread on the outside of the socket housing 6, ensuring the stability of the female end structure and avoiding poor contact due to vibration and other factors.
[0037] During use, the insertion phase Socket section: Press the female pin core 4 into the female rubber core 5, then align the female pin core 4 and female rubber core 5 assembly with the positioning groove of the socket housing 6 and insert it. Align the rubber core fixing cover 3 with the thread of the socket housing 6 and screw it in. Align the beveled nut 2 with the thread of the socket housing 6 and screw it in to the bottom. Similarly, align the hexagonal nut 1 with the thread of the socket housing 6 and screw it in to the appropriate position.
[0038] Plug part: Align and position the spring 8 and press it into the plug housing 7. Assemble and press the male pin 10 into the hole of the male rubber core 9. Align the assembled male rubber core 9 and male pin core 10 with the slot of the wire clamp 11 and assemble them. Align the assembled male rubber core 9, male pin core 10 and wire clamp 11 with the slot of the plug housing 7 and assemble them together into the plug housing 7 and the spring 8. Align the long nut of the wire clamp 11 with the internal threads of the assembled plug housing 7, spring 8, male rubber core 9, male pin core 10 and wire clamp 11 and screw it in.
[0039] Finally, connect the assembled plug to the socket.
[0040] Self-locking phase When the plug is inserted into place, the spring 8 is compressed by the internal structure of the socket and undergoes elastic deformation. The latches on both sides of the spring 8 will engage with the locking groove of the socket housing 6 to achieve mechanical self-locking and prevent the plug from being accidentally pulled out.
[0041] The first thread on the inner side of the long nut 12 engages with the second thread on the bottom of the spring 8 to fix the rubber core and the wire clamp 11, thereby enhancing the stability of the internal structure of the plug.
[0042] In summary, by adopting this modular design with an overall structure, damaged components can be replaced accordingly, thus reducing maintenance costs. The internal self-locking mechanism facilitates disassembly, preventing issues caused by prolonged external interference that could prevent disassembly. Furthermore, the use of larger connection cable interfaces improves the connection stability and transmission performance of the wiring harness. Example
[0043] Please see Figure 5 This is the second embodiment of the present utility model.
[0044] For example, snaps are provided on both sides of the surface of the spring 8, and the plug housing 7 is fixedly installed to the spring 8 through the socket.
[0045] Furthermore, the components are removable: each component is connected by threads such as the first to fifth threads and snap-fit connections. When a component is damaged, the corresponding part can be directly disassembled and replaced without the need for the entire component to be scrapped, thus reducing maintenance costs.
[0046] For example, the male rubber core 9 is sleeved on the outside of the male needle core 10, and the two male rubber cores and the male needle core are located inside the wire clamp 11.
[0047] Furthermore, the anti-jamming design: the internal self-locking structure avoids the disassembly difficulties caused by oxidation and corrosion after long-term use of traditional external threads, and can be easily disassembled by rotating the nut.
[0048] During use, the unlocking phase During disassembly, rotate the hexagonal nut 1 and the beveled nut 2 to release the locking force on the socket housing 6. At the same time, pull the plug outward, and the spring 8 will be elastically reset under force, and the buckle will disengage from the locking groove to achieve quick unlocking.
[0049] In summary, by adopting this modular approach with an overall structure, damaged parts can be replaced accordingly, thus reducing maintenance costs.
