Structure and assembly method of a rivet-welded waterproof connector base

Abstract

The invention discloses a rivet-welding combination type waterproof connector female seat structure, which includes a terminal assembly, an inner iron shell, an outer iron shell and a waterproof sheath; pins are used to cooperate with a multi-stage designed pin channel, and the inner iron shell and the inner iron shell are improved. The connection and fixing structure between the outer iron shells improves the scientificity and rationality of the assembly between the inner iron shell and the outer iron shell, making the assembly of the two more precise, tight and stable, not easy to loosen, and improving the overall performance; using riveting Welded integrated connection structure, this structure can not only realize the positioning, guidance and riveting of the outer iron shell to the inner iron shell, improve the connection and fixation performance of the inner and outer iron shells, but also reduce the occurrence of defective products, and can also integrate the inner and outer iron shells The welding position between the shells is extended from the corners to the bottom outer plane of the outer iron shell, which is convenient for welding operations and ensures the reliability of the welded structure. The invention also discloses an assembling method of the riveting and welding combination type waterproof connector female seat structure.

Description

technical field [0001] The invention relates to the structure of a waterproof connector female seat, in particular to a riveting and welding type waterproof connector female seat structure and an assembling method thereof. Background technique [0002] The waterproof connector female seat, especially the type-c connector female seat, generally includes four parts: the terminal assembly, the inner iron shell, the outer iron shell and the outer water sheath. The terminal assembly is the part of the contact device, and the inner iron shell is installed and fixed. The terminal assembly, and the part where the connector plug is inserted and pulled out, the outer iron shell is the part that installs and fixes the inner iron shell, improves the overall strength of the connector female seat, and coats the inner iron shell to improve the shielding performance. Covering the part of the connector that protects against water. The assembly process of the four major components of the wat...

AI Technical Summary

Problems solved by technology

First, the overall bonding between the inner and outer iron shells is poor, which affects the overall stability of the connector female seat

The quality of the connection and fixation of the inner and outer iron shells directly affects the overall performance of the connector base, because the connector base will face countless times of plugging and unplugging of the connector plug during actual use, and the dragging and shaking during plugging and unplugging etc. If the connection between the inner and outer iron shells is unstable, it will directly lead to loosening of the inner iron shell during use.

However, the inner and outer iron shells of the current connector base only rely on the elastic deformation of the outer iron shell for clamping and fixing, and the spot welding connection and fixing at the corners, and the connection and fixing strength is insufficient.

Second, the connection and fixing structure of the inner and outer iron shells of the current connector base is not conducive to assembly and production, and it is easy to produce defective products

Since the inner iron shell is clamped and fixed by using the elastic deformation of the outer iron shell, the inner iron shell is placed and pressed into the outer iron shell during assembly. Then, due to the lack of alignment and guidance assistance, it is impossible to accurately judge the inner iron shell. Whether the iron shell has been fully assembled in place, that is to say, in the end it is likely that the inner iron shell is not fully assembled in place, and there is still a wide gap between the inner iron shell and the outer iron shell, resulting in defective products; and, due to If the inner and outer iron shells are not assembled in place, then the follow-up at the corner will further lead to missing welding, and the inner and outer iron shells cannot be welded and fixed from the welding window

Moreover, setting the welding window between the inner and outer iron shells at the corner of the intersection of the three sides of the outer iron shell is not convenient for welding itself, and it is even more unfavorable for the fixed-point alignment welding of the inner and outer iron shells when realizing automatic assembly (two Assembling three-dimensional parts, the welding position is at the corner or at the edge seam, which is not convenient for alignment welding, especially in automatic welding, it is difficult to accurately locate and find the welding position; the most convenient welding position is at a certain plane. )

Moreover, due to the existence of the welding window of the outer iron shell, it will also affect the shielding effect to a certain extent

Third, in addition to the tightness of the assembly and bonding between the inner iron shell and the outer iron shell cannot be guaranteed, since the waterproof sheath is put on directly, there is no matching structure for positioning and fastening, so the fixing effect of the waterproof sheath cannot be guaranteed. Conditions that could lead to loosening or improper assembly

Therefore, there are still many unreasonable places in the current waterproof connector base structure and its assembly method, which need to be improved and perfected.
