[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figs. 1 to 3 As shown, this utility model provides a welding pull ring for an optical module, including a pull ring body 1. The pull ring body 1 includes a handhold part 101 and two cantilever arms 102 connected to the handhold part 101. The handhold part 101 and the two cantilever arms 102 form a semi-closed frame. A first spring piece 2 and a second spring piece 3 are welded to the inner sidewalls of the two cantilever arms 102.

[0029] In practice, the first spring 2 and the second spring 3 are both welded to the inner sides of the two cantilever 102 by resistance welding, which welds the required multiple points (6 points) on the cantilever 102 together. This solves the problem of welding multiple points at the same time, improves welding efficiency, and also solves the problem of different weld points caused by insufficient product space. The effect of resistance welding of multiple points (6 points) is consistent, which improves product stability. Moreover, resistance welding can improve the space for pull ring welding by bending the electrode.

[0030] Both the first spring 2 and the second spring 3 include a welded section 201, an arc-shaped section 202, and a bent section 203 arranged sequentially. The welded section 201 is welded to the inner wall of the cantilever 102. The welded section 201 is fixedly connected to the arc-shaped section 202. The end of the arc-shaped section 202 away from the welded section 201 is fixedly connected to the bent section 203. The bent section 203 is in close contact with the pull ring body 1. In this embodiment, the handheld part 101 is a U-shaped plastic part, and the cantilever 102 is a strip-shaped hardware part used for unlocking. The two cantilever 102s are respectively fixedly connected to both sides of the handheld part 101.

[0031] In this embodiment, the welding segment 201 is welded to the inner wall of the cantilever 102 by resistance welding through multiple welding points 4.

[0032] In actual implementation, the number of the welding points 4 is 2-10 according to actual needs. In this embodiment, the number of the welding points 4 is six. The six welding points 4 are arranged in three rows and two columns along the transverse direction of the welding section 201.

[0033] The welding section 201 of the first elastic sheet 2 and the second elastic sheet 3 is welded on the inner side wall of the cantilever 102 in a resistance welding manner through the plurality of welding points 4, which avoids the stability problem of the traditional pull ring caused by single-point connection or insufficient connection area. Meanwhile, the arrangement of the first elastic sheet 2 and the second elastic sheet 3 reduces the gap between the shell of the optical module and the pull ring after the pull ring is mounted on the optical template, and the shell of the optical module can be in better electrical contact with the pull ring, thereby achieving the grounding effect.

[0034] In this embodiment, the welding section 201, the arc-shaped section 202 and the bending section 203 are integrally formed.

[0035] In this embodiment, the arc-shaped section 202 is provided with a welding scar 5.

[0036] In this embodiment, the first elastic sheet 2 and the second elastic sheet 3 are both conductive parts. The conductive part 3 can be a part made of the same material, such as metal, or can be a multi-layer material composite, such as metal, conductive foam, conductive glue and the like.

[0037] In actual implementation, the outwardly convex side of the arc-shaped section 202 and the bending section 203 is coated with a smooth coating 6, which reduces the abrasion of the pull ring and the optical module during the movement of the elastic sheet, prolongs the service life of the first elastic sheet 2 and the second elastic sheet 3, and is conducive to the use of the optical module.

[0038] The process of manufacturing the utility model is as follows:

[0039] (1) The first elastic sheet 2 is welded to the inner side wall of one cantilever 102 of the pull ring body 1: first, the pull ring body 1 is placed on the clamp, and the convex part on the clamp located on the side surface of the cantilever 102 is used to position the welding position of the first elastic sheet 2 as a whole; then, the first elastic sheet 2 is placed on the inner side wall of the cantilever 102, and a new clamp is used to clamp the first elastic sheet 2 at the position to be welded, so as to ensure the correct position of the first elastic sheet 2 during welding; finally, the resistance welding is started, and the welding of the first elastic sheet 2 is completed.

[0040] (2) The second elastic sheet 3 is welded to the inner side wall of the other cantilever 102 of the pull ring body 1: first, the pull ring body 1 is placed on the clamp, and the convex part on the clamp located on the side surface of the cantilever 102 is used to position the welding position of the second elastic sheet 3 as a whole; then, the second elastic sheet 3 is placed on the inner side wall of the cantilever 102, and a new clamp is used to clamp the second elastic sheet 3 at the position to be welded, so as to ensure the correct position of the second elastic sheet 3 during welding; finally, the resistance welding is started, and the welding of the second elastic sheet 3 is completed.

[0041] After the welding of the first spring piece 2 and the second spring piece 3 on the pull ring body 1 is completed, the optical module welding pull ring can be applied in the optical module. When the pull ring is applied in the optical module, pulling the pull ring can cause the unlocking component to move relative to the housing, thereby allowing the optical module to be freely pulled out. The specific application of the pull ring in the optical module is existing technology and will not be described in detail here.

[0042] In summary, this utility model uses multiple welding points 4 to weld the welding sections 201 of the first spring piece 2 and the second spring piece 3 to the inner wall of the cantilever 102 via resistance welding. This avoids the stability problems caused by single-point connection or insufficient connection area in traditional pull ring parts, and also achieves the grounding function. The use of resistance welding solves the problem of welding multiple points at the same time, improves welding efficiency, and also solves the problem of different welding points due to insufficient product space. The multiple points (6 points) produced by resistance welding have a consistent effect, which improves product stability. Moreover, resistance welding can improve the welding space of the pull ring by bending the electrode. The smooth coating 6 reduces the wear of the pull ring and optical module during the movement of the spring piece, extends the service life of the spring piece, and is beneficial to the use of the optical module.
