Problems solved by technology

[0003] Aiming at the above-mentioned technical problems, the present invention provides an angled connector welding tool and its use method, which adopts a new structure and solves the problem that the solder easily flows into the housing cavity when the existing angled connector without steps is removed and welded. The problem is to use the thermal expansion and contraction of the tooling to prevent solder from flowing into the shell cavity, causing unnecessary scrapping. The pass rate of using this tooling to remove gold is over 90%, and then use this tooling to weld the outer conductor after removing gold. The rate is over 90%

Embodiment 1

[0029] Such as figure 1 with figure 2 As shown, for SMA-JWB2 and other bent connector shells, there is no step to remove gold and solder is easy to flow into the shell cavity during welding. A new type of bent welding tool is designed. The bent connector welding tool includes a cylindrical shell 1 and a through hole 2 set in the middle of the cylindrical shell 1, wherein: the outer wall of the cylindrical shell 1 is provided with a side hole 3 and an exit groove 4. The axis of the side hole 3 is perpendicular to and intersects the axis of the cylindrical shell 1 , the axis of the exit groove 4 is parallel to the axis of the cylindrical shell 1 , and the exit groove 4 communicates with the side hole 3 .

[0030] Specifically, the diameter of the side hole 3 is consistent with the width of the exit groove 4 , and the exit groove 4 communicates with the diameter of the side hole 3 . The columnar shell 1 is made of polytetrafluoroethylene, which can avoid soldering into the cav...

Embodiment 2

[0033] Such as image 3 As shown, the method of using the elbow connector welding tool includes the following steps:

[0034] 1) Insert the end of the bent connector welding tool with the side hole 3 and the exit groove 4 into the inner cavity 502 of the bent housing 501 of the connector 5 to ensure that the cylindrical shell 1 is closely attached to the wall of the inner cavity 502;

[0035] 2) Rotate the welding tool of the bent connector so that the side hole 3 is aligned with the inner outlet hole of the outer conductor installation channel 503 of the connector 5, and then insert the outer conductor 6 into the outer conductor installation channel 503 and the side hole 3 in sequence to ensure The end of the outer conductor 6 is connected with the inner conductor 7;

[0036] 3) Use a resistance welding machine to remove the gold from the outer conductor 6. After the gold is removed, the solder evenly adheres to the inner wall of the outer conductor installation channel 503....

Abstract

The invention discloses a bent connector welding tool and a using method thereof, and belongs to the technical field of connector welding. The bent connector welding tool comprises a columnar shell and a through hole formed in the middle of the columnar shell. A side hole and a retreating groove are formed in the outer wall of the columnar shell, the axis of the side hole is perpendicular to and intersects with the axis of the columnar shell, the axis of the retreating groove is parallel to the axis of the columnar shell, and the retreating groove is communicated with the side hole. By adopting the novel structure, the technical problem that soldering tin easily flows into the cavity of the shell during gold removal and welding of an existing bent step-free connector is solved, unnecessaryscrapping caused by the fact that the soldering tin flows into the cavity of the shell due to the fact that the tool expands with heat and contracts with cold is avoided, the gold removal percent ofpass reaches 90% or above when the tool is used, after gold is removed, the tool is used for welding an outer conductor, and the percent of pass reaches more than 90%.

Description

technical field [0001] The invention belongs to the technical field of connector welding, and in particular relates to a bending connector welding tool and a using method thereof. Background technique [0002] With the maturity of the market and the development of technology, customers have more and more demands for semi-rigid cable assemblies, and the requirements for welding are becoming more and more stringent. When the Cable and Components Division is processing cable assemblies with curved connectors such as SMA-JWB2 without steps, there are the following problems: 1) When the outer conductor of the connector is degolded, the solder with the stepless structure of the shell will easily flow into the cavity of the shell , causing some connectors to be scrapped; 2) When the outer conductor of the connector is welded, the solder of the shell without a step structure easily flows into the cavity of the shell, and the excess solder cannot be removed, which has hidden quality ...
