Description

TECHNICAL FIELD

[0001] The utility model relates to connector technical field especially a positioning structure of connector terminal. BACKGROUND

[0002] Nowadays, optical fibers are widely used, and the optical fiber technology develops rapidly. In high-precision optical instruments, especially in the fields of laser and sensors, optical fibers are mostly used for optical signal transmission. Due to the accuracy requirement of optical signal transmission, the end face of the optical fiber connection also has high quality requirement standards. The end face of the optical fiber connection usually needs to be glued, washed, and ground in multiple processes to complete the production. The grinding process in completing these works needs to use an optical fiber grinding clamp to clamp and place the end face of the optical fiber connection on an optical fiber grinding machine for grinding. The grinding methods mainly include vertical grinding and inclined grinding, and different grinding methods need to be adopted for different types of optical fiber end faces.

[0003] At present, there are many grinding clamps on the market that can grind the end face of the optical fiber. For example, a Chinese utility model patent application with the patent publication number CN202462210U discloses an APC short plug core optical fiber connector grinding clamp, which comprises a circular core plate, a plurality of plug core fixing holes are uniformly arranged on the core plate, a positioning and clamping mechanism is arranged outside the plug core fixing hole, and the included angle between the hole axis of the plug core fixing hole and the vertical direction is 4-8.6°.

It uses independent pressure to fix and lock the side surface of the APC short plug core, and simultaneously uses the angle of the plug core fixing hole to correct the angle of the APC short plug core, effectively solving the problems of low production efficiency, large grinding angle difference, and unguaranteed product quality during the grinding of the end face of the APC short plug core optical fiber connector.

[0004] However, the existing grinding clamp still has the following disadvantages:

[0005] In the technical scheme, the plug core is positioned by setting a plurality of plug core fixing holes on the core plate, and the plug core is fixed by the positioning and clamping mechanism, without setting an additional positioning member. This way, the steps of plugging and unplugging the plug core are more, and the operation is not convenient. Moreover, the grinding clamp can only be adapted to one type of APC short plug core connector, and is not suitable for UPC short plug core connectors, so a new clamp needs to be replaced, which has poor applicability and great limitation.

[0025] In this embodiment, the positioning member body 1 is used to position the external connector 2, and two elastic buckles 110 are arranged in the connecting hole 11. The elastic buckles 110 are not easy to be separated from the external connector 2, and the traditional buckling and plugging method is broken. The elastic buckles 110 can effectively simplify the plugging steps, so that the plugging is more convenient. In addition, when different connectors such as UPC short insertion core and APC short insertion core are ground, the positioning member body 1 can be replaced according to the needs, which is very convenient and has excellent applicability.

[0026] The elastic buckle 110 includes an elastic section 111 which is integrally formed with the positioning member body 1 and has elasticity, and a buckle section 112 which is integrally formed with the elastic section. The reverse buckle part 120 is formed on the buckle section 112. The elastic buckle 110 is formed on the side wall of the positioning member body 1 and extends obliquely into the connecting hole 11. When plugging, the elastic section 111 has elasticity, so that the buckle section 112 and the external connector 2 form an elastic buckle connection. When the external connector 2 is inserted, it is only necessary to align the external connector 2 with the connecting hole 11 of the positioning member body 1, and then press the external connector 2 slightly, so that the reverse buckle part 120 of the elastic buckle 110 is buckled in the clamping groove 21 of the external connector 2. Under the premise of ensuring stable connection, the installation steps are effectively simplified.

[0027] The clamping groove 21 is protruded with a locking protrusion 210 which is distributed transversely and used for matching the clamping position of the reverse buckle part 120.

Here, after the external connector 2 is inserted into the positioning member body 1, the first pressing part 113 and the second pressing part 114 are respectively clamped in the first sunken groove 211 and the second sunken groove 212; when it is needed to pull out the external connector 2, a certain force needs to be applied to move the external connector 2 upward, at the same time, the first inclined surface 213 in the first sunken groove 211 will move upward synchronously and push the first pressing part 113 to expand outward, the second inclined surface 214 in the second sunken groove 212 will move upward synchronously and push the second pressing part 114 to expand outward, so that the reverse buckle part 120 of the elastic buckle 110 is completely separated from the locking protrusion 210, and the unlocking is completed.

[0029] The reverse buckle part 120 is formed with an inner abutting surface 121 for limiting the external connector 2, and the card slot 21 is correspondingly formed with an outer abutting surface 220. Here, in order to avoid damage caused by excessive insertion of the external connector 2 during insertion, the inner abutting surface 121 and the outer abutting surface 220 are respectively arranged on the reverse buckle part 120 and the external connector 2, when inserted in place, the inner abutting surface 121 and the outer abutting surface 220 form abutting limiting, and excessive insertion is avoided.

Here, in order to avoid damage caused by excessive insertion of the external connector 2 during insertion, the limiting strip groove 13 and the limiting protrusion 23 are respectively arranged on the positioning member body 1 and the external connector 2, when inserted in place, the limiting protrusion 23 and the limiting strip groove 13 form abutting limiting, and excessive insertion is avoided, and the damage rate is effectively reduced.

[0031] The positioning member body 1 is square, and the positioning member body 1 is further provided with a first extension edge 101 and a second extension edge 102 on both sides. Here, the first extension edge 101 and the second extension edge 102 are both stepped protrusions.

[0032] The external connector 2 is further provided with a core head 29 protruding outward, and the core head 29 penetrates through the connecting hole 11 and extends out of the lower end surface of the positioning member body 1.

[0033] The external connector 2 is further provided with a core head 29 protruding outward, and the core head 29 penetrates through the connecting hole 11 and extends out of the lower end surface of the positioning member body 1.
