Description

Technical Field

[0001] This application relates to the field of electrical component technology, and more particularly to the field of power connector technology, specifically to a connector. Background Technology

[0002] DC connectors typically consist of a male connector (male plug) and a female connector (female socket). The male connector uses a metal electrode protruding from its plastic tip to insert into the female socket's hole, achieving connection and conductivity. However, this connection has poor reliability. Frequent insertion and removal, coupled with wear on both the male and female connectors, can reduce interference and lead to connection failure. Furthermore, external impacts can deform the metal electrodes, damaging either the male or female connector. Utility Model Content

[0016] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of this application, including various details to aid understanding. These should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this application. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0017] like Figures 1-4 As shown, the connector according to an embodiment of this application includes a male plug 1, a female connector 2, a pawl 4, and a ratchet 3. The male plug 1 includes a first insulating portion 11 and a first electrode 12, the first electrode 12 protruding from the outer surface of the male plug 1. The female connector 2 includes a second insulating portion 21 and a second electrode 22. The second insulating portion 21 has a socket, and the second electrode 22 is located inside the socket. A portion of the first insulating portion 11 is rotatably fixed inside the socket by means of an axis about the socket, so as to facilitate electrical connection between the first electrode 12 and the second electrode. The ratchet 3 is connected to the first insulating portion 11, and the pawl 4 is connected to the second insulating portion 21, and the pawl 4 engages with the ratchet 3.

[0018] According to the connector of this application embodiment, by setting a portion of the first insulating part 11 to rotate around the axis of the socket to fix it inside the socket of the second insulating part 21, the electrical connection of the first electrode 12 and the second electrode 22 is ensured. At this time, when the male plug 1 and the female connector 2 are subjected to external impact, the portion of the first insulating part 11 located inside the socket is subjected to radial pressure instead of the first electrode 12. Since the first insulating part 11 has higher strength than the first electrode 12, the first electrode 12 and the interfering second electrode 22 are less prone to bending deformation and damage. Simultaneously, after a portion of the first insulating part 11 is fixed in the socket, the pawl 4 on the second insulating part 21 engages with the ratchet 3 of the first insulating part 11, thereby preventing the first insulating part 11 from rotating in the opposite direction around the axis of the socket, effectively preventing the male plug 1 from accidentally disengaging from the female connector 2, resulting in high reliability of the connection between the male plug 1 and the female connector 2.

[0019] It should be noted that the outer contour of the first insulating part 11 is cylindrical, and the first insulating part 11 is fixed in the socket by rotating clockwise around the axis of the socket.

[0020] In some embodiments of this application, such as Figures 1-4 As shown, the outer peripheral surface of the first insulating part 11 is provided with an external thread, and the inner peripheral surface of the insertion hole is provided with an internal thread, and the internal thread and the external thread are threadedly engaged.

[0021] That is, the first insulating part 11 and the second insulating part 21 are connected by threads, which makes the connection between the two convenient and reliable. Moreover, the structure of the first insulating part 11 and the second insulating part 21 is simple and the manufacturing cost is low.

[0022] Specifically, when the first insulating part 11 rotates clockwise relative to the second insulating part 21 to gradually screw into the socket, when it is felt that the first insulating part 11 can no longer rotate, the first insulating part 11 abuts against the bottom surface of the socket. At this time, it means that the first insulating part 11 is screwed into place, and the electrical connection between the first electrode 12 and the second electrode 22 is highly reliable.

[0023] It should be noted that the first insulating part 11 and the second insulating part 21 can also be rotatably engaged. For example, a first protrusion is provided on the inner circumferential surface of the socket, and a second protrusion is provided on the outer circumferential surface of the first insulating part 11. With the second protrusion and the first protrusion arranged at intervals along the circumference of the socket, the first insulating part 11 is inserted into the socket, and then the first insulating part 11 is rotated to move the second protrusion to the side of the first protrusion away from the opening of the socket, thus completing the connection between the first insulating part 11 and the second insulating part 21.

[0024] In some embodiments of this application, the first electrode 12 is a hollow cylinder and the second electrode 22 is a cylinder. The first electrode 12 is adapted to be inserted into the socket and fitted with the second electrode 22.

[0025] Therefore, during the threaded engagement of the first insulating part 11 and the second insulating part 21, the second electrode 22 can also be rotatably inserted into the through hole formed by the first electrode 12. The electrical connection between the first electrode 12 and the second electrode 22 and the connection between the first insulating part 11 and the second insulating part 21 do not interfere with each other, and the electrical connection between the first electrode 12 and the second electrode 22 is more reliable.

[0026] like Figures 1-3 As shown, the length of the first electrode 12 is greater than or equal to the length of the second electrode 22, the through hole formed by the first electrode 12 is a circular hole, and the second electrode 22 is inserted into the circular hole of the first electrode 12.

[0027] In some embodiments of this application, the ratchet 3 is located on the side of the external thread facing away from the first electrode 12, and the teeth of the ratchet 3 protrude from the outer peripheral surface of the first insulating part 11. The insertion hole includes a first hole segment 211 and a second hole segment 212 arranged along its axial direction. The second hole segment 212 is open at one end facing away from the first hole segment 211. The inner peripheral surface of the first hole segment 211 is provided with an internal thread. The diameter of the second hole segment 212 is larger than the diameter of the first hole segment 211. A stepped surface is formed at the connection between the first hole segment 211 and the second hole segment 212. The free end of the pawl 4 is located inside the second hole segment 212 and its orthographic projection along the axial direction of the insertion hole coincides with the orthographic projection of the stepped surface.

[0028] This ensures that the first insulating part 11 will not interfere with the pawl 4 during the engagement of the external and internal threads, and also ensures that the pawl 4 will mesh with the ratchet 3 after the engagement of the external and internal threads is completed, thereby preventing the first insulating part 11 from rotating counterclockwise relative to the second insulating part 21, resulting in high reliability of the connection between the male plug 1 and the female plug 2.

[0029] Specifically, such as Figures 1-4 As shown, the ratchet 3 is arranged coaxially with the first insulating part 11. The diameter of the first insulating part 11 is equal at any position. The outer diameter of the ratchet 3 is larger than the diameter of the first hole section 211 and smaller than the diameter of the second hole section 212. The ratchet 3 is clearance-fitted into the second hole section 212. The pawl 4 can elastically deform outward along the radial direction of the second hole section 212 to disengage from the ratchet 3, thereby facilitating the separation of the male plug 1 and the female plug 2. Furthermore, after the external thread of the first insulating part 11 is engaged with the internal thread at the first hole section 211, the ratchet 3 is spaced apart from the stepped surface.

[0030] In some embodiments of this application, the outer peripheral surface of the second insulating part 21 is provided with a relief groove 213 that communicates with the second hole segment 212, and the free end of the pawl 4 can move into the relief groove 213 through elastic deformation.

[0031] This allows the pawl 4 to disengage from the ratchet 3, making it easier for the male plug 1 and female connector 2 to separate. It also effectively reduces the diameter of the second hole section 212 and the outer diameter of the second insulation part 21, resulting in a smaller connector size and lower cost.

[0032] For example, such as Figure 3 and Figure 4 As shown, the thickness of the pawl 4 gradually decreases towards its free end, and the fixed end of the pawl 4 is connected to the side of the clearance groove 213.

[0033] It should be noted that the pawl 4 can also be pivotally connected to the second insulating part 21, and an elastic element is connected between the pawl 4 and the second insulating part 21, which presses the pawl 4 against the ratchet 3. The elastic element includes, but is not limited to, a compression spring or a torsion spring.

[0034] In some embodiments of this application, the clearance groove 213 extends circumferentially along the second hole segment 212, and a portion of the pawl 4 protrudes from the outer peripheral surface of the second insulating portion 21.

[0035] This makes it easy for the user to pull the pawl 4 away from the ratchet 3 by the part of the pawl 4 that protrudes from the outer peripheral surface of the second insulating part 21, so as to separate the first insulating part 11 and the second insulating part 21. The disassembly of the male plug 1 and the female connector 2 is easy.

[0036] For example, the middle part of the pawl 4 or the portion near the free end protrudes from the outer peripheral surface of the second insulating part 21, and the fixed end of the pawl 4 is connected to the opposite end of the clearance groove 213 along the circumferential direction of the second hole section 212.

[0037] In some embodiments of this application, the connector further includes a paddle 5, one end of which is connected to the pawl 4, and the other end of which protrudes from the outer peripheral surface of the second insulating portion 21.

[0038] That is, the pawl 4 can be disengaged from the ratchet 3 simply by moving or pulling the lever 5, thereby separating the first insulating part 11 and the second insulating part 21. Moreover, the lever 5 is easier for the user to hold, making the separation operation of the male plug 1 and the female connector 2 more convenient.

[0039] For example, the paddle 5 is connected to the middle or a portion near the free end of the pawl 4. The paddle 5 can be fitted against the outer peripheral surface of the second insulating part 21, or it can be bent to cover the clearance groove 213 to prevent impurities from entering the clearance groove 213. The outer surface of the paddle 5 may be provided with anti-slip texture.

[0040] In some embodiments of this application, at least one of the first insulating part 11 and the second insulating part 21 is a plastic part.

[0041] That is, the first insulating part 11 and / or the second insulating part 21 are integrally formed, so that at least one of them has a simple structure, high strength and low cost, and the external thread and internal thread are easy to process on the first insulating part 11 and the second insulating part 21 respectively.

[0042] In some embodiments of this application, the ratchet 3 and the first insulating part 11 are integrally formed. That is, the ratchet 3 can also be a plastic part, and the ratchet 3 and the first insulating part 11 are integrally injection molded, which reduces the manufacturing cost of both.

[0043] Alternatively, the ratchet 3 can be pre-embedded in the first insulating part 11. In this case, the ratchet 3 can be made of a higher strength material, such as a metal part. In this case, the ratchet 3 can be pre-injected into the first insulating part 11 to make the connection between the two high.

[0044] In some embodiments of this application, the pawl 4 is embedded in the second insulating portion 21.

[0045] That is, the pawl 4 is a metal part, which is pre-injected onto the second insulating part 21 to ensure high connection strength between the two. This arrangement also facilitates the elastic bending of the pawl 4 relative to the second insulating part 21, so as to facilitate the separation of the pawl 4 from the ratchet 3, and to facilitate the separation of the male plug 1 and the female connector 2.

[0046] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
