Technical Field

[0001] The utility model relates to the technical field of mobile phone antenna installation and positioning, in particular to a multi-frequency mobile phone antenna installation and positioning mechanism. Background Art

[0002] The multi-frequency mobile phone antenna is an elastic sheet, which is generally fixed to the mobile phone housing by laser welding. However, in the prior art, because the mobile phone antenna parts are too small, they need to be welded to the mobile phone housing, and the mobile phone needs to be positioned, so a multi-frequency mobile phone antenna installation positioning mechanism is used;

[0003] In a mobile phone antenna welding auxiliary positioning machine disclosed in publication number CN202021124385.X, a guide rod passes through a guide groove for sliding connection, and a spring is sleeved on the left outer wall of the guide rod. According to the elastic force of the spring, the clamping block can be smoothly pushed to move to the right in the clamping groove, and the mobile phone in the clamping groove is further automatically positioned. The connecting block passes through the through groove and is fixedly connected with the positioning iron block. The clamping block can further drive the positioning iron block to move smoothly to the right in the fixed groove, and the electromagnet is controlled to generate magnetic attraction to attract the fixed positioning iron block, thereby realizing the fixing operation of the clamping block on the mobile phone, which can avoid damage to the mobile phone due to excessive force when the clamping block clamps the mobile phone;

[0004] However, the above solution still has the following problems during use: when in use, the mobile phone is clamped and fixed by the elastic force of the spring, the spring can undergo elastic deformation with weak stability, and the orientation is single when limiting. When the antenna is installed, it is easy to deviate, thereby affecting the overall assembly quality of the mobile phone.

[0005] Therefore, we propose a multi-frequency mobile phone antenna installation and positioning mechanism to solve the above-mentioned problems. Utility Model Content
