[0038] Compared to the embodiments shown in the drawings, feasible embodiments within the scope of protection of the present disclosure may have fewer components, additional components not shown in the drawings, different components, differently arranged components, or differently connected components, etc. In addition, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.
[0039] Example 1
[0040] like Figure 1-Figure 2 The pluggable connector shown in the figure primarily comprises a fixing unit 10 and a mating unit 20, namely the female and male ends of the connector. The female end of the connector is the portion of the connector pair that corresponds to the male end. When used in pairs, the female end is typically designed with a receptacle or slot to receive the pin or plug on the male end. This design allows the male and female ends to be electrically connected or disconnected by mating or plugging and unplugging.
[0041] Specifically, refer to Figure 2-Figure 3 The connector of the present application is provided with a detachable locking member 30 at the top of the plug-in unit 20, and a locking block 121 and a locking groove 12 are provided on the fixed unit 10 to lock and limit the locking member 30. In particular, the fixed unit 10 is also provided with a terminal cavity 11 for mating and connecting with the plug-in unit 20, and the plug-in unit 20 is provided with a plug-in portion 21 that is inserted into the terminal cavity 11. The locking groove 12 is located above the terminal cavity 11, and the locking member 30 is also located above the plug-in portion 21. The end of the locking member 30 is provided with a locking block 31 that cooperates with the locking block 121.
[0042] In order to improve the applicable scope of cooperation between the locking member 30 and the locking block 121, and to improve the cooperation tolerance between the terminals on the fixing unit 10 and the plug-in unit 20, the locking member 30 itself is detachably arranged on the top of the plug-in unit 20, and an adjustment structure 335 is provided on the locking member 30.
[0043] In this embodiment, referring to Figure 3-Figure 5The top of the plug-in unit 20 is provided with a groove 22 for connecting the latch 30, and the bottom of the latch 30 is provided with two L-shaped connecting arms 33. The connecting arms 33 are integral with the latch 30 and extend away from the plug-in portion 21. The opening of the groove 22 is arranged toward the plug-in portion 21, that is, the latch 30 is inserted into the groove 22 backward along the side of the plug-in portion 21, and the latch 30 can rotate counterclockwise with the end of the connecting arm 33 as a fulcrum, thereby entering an energy storage state. When the plug-in unit 20 is inserted into the locking groove 12 of the fixed unit 10, the latch 30 is released, so that the locking block 31 of the latch 30 cooperates with the locking block 121 to lock.
[0044] The connecting arm 33 includes a portion A 331 that engages with the groove 22 and a portion B 332 that connects the portion A 331 to the bottom of the locking member 30. Specifically, the connecting arm 33 consists of the portion A 331 and the portion B 332, with the adjustment structure 335 disposed on the top surface of the portion A 331. Specifically, the locking member 30 rotates around the bottom end of the portion B 332 of the connecting arm 33, with the angle between the portion A 331 and the portion B 332 being 90°.
[0045] Portion B 332 is also arranged at a 90° angle to the bottom of the latch 30. That is, the connecting arm 33 is perpendicular to the bottom of the latch 30, while portion A 331 is parallel to the bottom surface of the latch 30. Specifically, the length of portion B 332 should be greater than the height of the recess 22 by a certain distance, thereby forming a rotation area 24 between the bottom surface of the latch 30 and the top surface of the recess 22 for rotation of the latch 30.
[0046] A handle portion 32 is provided at the end of the top surface of the locking member 30 . The handle portion 32 protrudes upward. The operator can press the handle portion 32 downward or backward to rotate the locking member 30 counterclockwise to tilt the block 31 .
[0047] Specifically, the adjustment structure 335 is composed of multiple right-angled triangular protrusions, each equidistantly spaced on the top surface of section A 331. The top of the recess 22 is provided with an adjustment slot 221 that mates with the protrusions of the adjustment structure 335. The number of adjustment slots 221 is increased by at least one. That is, when the adjustment structure 335 has four protrusions, the number of adjustment slots 221 can be five, six, or seven. As the difference between the number of adjustment slots 221 and the number of protrusions increases, the adjustable range of the latch 30 increases. The spacing between the two protrusions determines the unit distance of adjustment of the latch 30.
[0048] In order to ensure a good adjustment effect, the distance between the protrusions is equal to the distance between the adjustment slots 221 .
[0049] By adjusting the position of the locking member 30 on the plug-in unit 20, the insertion distance between the plug-in unit 20 and the fixing unit 10 can be adjusted, thereby adjusting the mating position of the terminals therebetween, further improving the applicability of the connector.
[0050] Furthermore, in order to facilitate the adjustment of the position of the adjustment structure 335, a clearance groove 222 is provided at the bottom of the groove 22. The clearance groove 222 is gradually inclined inward from near the opening, that is, when the locking member 30 rotates counterclockwise, the B part 332 of the connecting arm 33 also rotates counterclockwise and is close to the bottom surface of the clearance groove 222. At this time, the protrusion of the adjustment device and the adjustment groove 221 are released from the limit, and the locking member 30 can be dragged to adjust the position.
[0051] Example 2
[0052] like Figure 1 、 Figure 2 、 Figure 4 As shown, based on the embodiment 1, the plug connector of the present invention further has an auxiliary limiting structure, wherein the auxiliary limiting structure is composed of a limiting groove 13 and a limiting block 23 .
[0053] Specifically, the fixing unit 10 is further provided with a limiting groove 13 below the terminal cavity 11, and the plug-in unit 20 is provided with a limiting block 23 that cooperates with the limiting groove 13. The limiting block 23 is located below the plug-in portion 21, and the number of the limiting blocks 23 is the same as the number of terminals in the plug-in unit 20, and each protrusion is provided below a terminal.
[0054] In this embodiment, the limiting groove 13 and the limiting block 23 are in interference fit, that is, the fixing unit 10 and the plug-in unit 20 are locked by the locking member 30 at the top and the limiting block 23 at the bottom.
[0055] The limit block 23 and the limit groove 13 are both columnar structures, and in order to adapt to the adjustment structure 335 of the lock component 30, the groove depth of the limit groove 13 should be greater than the length of the limit block 23, and the difference between the two should be greater than or equal to the adjustable distance of the adjustment structure 335. The limit groove 13 and the limit block 23 also have a guiding and anti-mistake function.
[0056] It can be seen from the above that the technical solution disclosed in Example 2 is an improvement on the technical solution disclosed in Example 1.
[0057] Example 3
[0058] In this embodiment, referring to Figure 6-Figure 8The difference from Examples 1 and 2 is that the top of the plug-in unit 20 is provided with a groove 22 for connecting the latch 30, and the bottom of the latch 30 is provided with two vertically downwardly arranged pillars 333. A connecting plate 334 is provided between the two pillars 333. The pillars 333, connecting plate 334, and latch 30 are an integral structure, and the connecting plate 334 extends away from the plug-in portion 21. The opening of the groove 22 is arranged toward the plug-in portion 21, that is, the latch 30 is inserted backward into the groove 22 along the side of the plug-in portion 21, and the latch 30 can rotate counterclockwise with the end of the pillar 333 as a fulcrum, thereby entering an energy storage state. When the plug-in unit 20 is inserted into the locking groove 12 of the fixed unit 10, the latch 30 is released, so that the locking block 31 of the latch 30 cooperates with the locking block 121 to lock.
[0059] The connecting plate 334 and the support 333 are arranged at a 90-degree angle, and the adjustment structure 335 is provided on the top surface of the connecting plate 334. The support 333 and the bottom surface of the locking member 30 are also arranged at a 90-degree angle, that is, the connecting plate 334 and the bottom surface of the locking member 30 are arranged parallel to each other. In particular, the length of the support 333 should be greater than the height of the groove 22 by a certain distance, so that a rotation area 24 is formed between the bottom surface of the locking member 30 and the top surface of the groove 22 for the locking member 30 to rotate.
[0060] A handle portion 32 is provided at the end of the top surface of the locking member 30 . The handle portion 32 protrudes upward. The operator can press the handle portion 32 downward or backward to rotate the locking member 30 counterclockwise to tilt the block 31 .
[0061] Specifically, the adjustment structure 335 is composed of multiple right-angled triangular protrusions, each equidistantly spaced on the top surface of section A 331. The top of the recess 22 is provided with an adjustment slot 221 that mates with the protrusions of the adjustment structure 335. The number of adjustment slots 221 is increased by at least one. That is, when the adjustment structure 335 has four protrusions, the number of adjustment slots 221 can be five, six, or seven. As the difference between the number of adjustment slots 221 and the number of protrusions increases, the adjustable range of the latch 30 increases. The spacing between the two protrusions determines the unit distance of adjustment of the latch 30.
[0062] In order to ensure a good adjustment effect, the distance between the protrusions is equal to the distance between the adjustment slots 221 .
[0063] By adjusting the position of the locking member 30 on the plug-in unit 20, the insertion distance between the plug-in unit 20 and the fixing unit 10 can be adjusted, thereby adjusting the mating position of the terminals therebetween, further improving the applicability of the connector.
[0064] Furthermore, to further enhance the adjustment effect of the clearance groove 222 and prevent the locking member 30 from becoming unstable, the clearance groove 222 is filled with an elastic material 223. The elastic material 223 can be made of sponge, rubber, gel, etc. In particular, a support surface 224 is provided at the front end and opening of the clearance groove 222. The support surface 224 and the elastic material 223 increase the connection strength and stability of the locking member 30. After the locking member 30 is rotated counterclockwise, the elastic material 223 can also assist in resetting the locking member 30, thereby preventing the pillar 333 and the connecting plate 334 from being overused and shortening their lifespan.
[0065] It can be seen from the above that the technical solution disclosed in Example 3 is an improvement on the technical solutions disclosed in Example 1 and Example 2.
[0066] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements made to the technical solution of the present invention by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention. The technical content for which protection is sought in the present invention is fully set forth in the claims.
