Background

In the communication industry, users often need to fully consider how to conveniently connect the inside and the outside of the device through a third core in the design of related power connectors and cable assemblies in consideration of the safety problem of device grounding, and it is a common solution to connect a power connector installed outside the device with a PCB board installed inside the device through a wire. Unlike splicing and wire wrapping, the connection of the wires to the outer housing of the power connector by soldering is clearly more reliable, and although direct soldering of the wires to the outer housing of the power connector can satisfy performance requirements, it also imposes different degrees of restrictions on the appearance and structure of the product.

At present, when a product is designed, in order to fully connect the outer shell 1 of the power connector with the lead 3, the lead is often directly scattered and then welded with the outer shell of the power connector in a production stage (as shown in fig. 1), so that the connection of the third core is realized, the difficulty of product welding is increased, the size of a welding position cannot be accurately controlled in the welding process, and when the requirement of a user on the appearance size of the product is strict, other measures, such as outer layer plastic package or glue pouring (as shown in fig. 2), must be adopted to supplement the defect that the welding position is too large.

Disclosure of Invention

In view of the above problems, an object of the present invention is to provide a structure that facilitates product welding and does not affect the appearance quality of the product on the premise that the lead is in full contact with the outer shell of the power connector.

The purpose of the invention is realized by adopting the following technical scheme. The structure capable of facilitating welding comprises an installation base body and a welding hole or a welding groove which is positioned on the installation base body and is lower than the outer wall of the end part of the metal shell when the installation base body is connected to the end face of the metal shell, wherein the end part of the welding hole or the welding groove extends in the direction far away from the axis of the welding hole or the welding groove to form an anti-falling part used for enhancing the pulling-out force of a lead in the axis direction of the metal shell after the lead is soldered.

Furthermore, the anti-dropping part is a conical surface or a spherical surface or a paraboloid which is gradually expanded and complete in the circumferential direction.

The purpose of the invention is realized by adopting the following technical scheme. According to the outer shell of the power connector adopting the structure, the end face of the outer shell is connected with the mounting base body extending along the direction vertical to the end face of the outer shell, the mounting base body is provided with the welding hole or the welding groove lower than the outer wall of the end part of the outer shell, and the end part of the welding hole or the welding groove close to the axis of the outer shell extends along the direction far away from the axis of the welding hole or the welding groove to form the anti-falling part for enhancing the pull-off force of the lead in the axis direction of the outer shell of the power connector after the lead is soldered.

Furthermore, the anti-dropping part is a conical surface or a spherical surface or a paraboloid which is gradually expanded and complete in the circumferential direction.

The structure convenient for welding has the following advantages:

1. the lead is fully contacted with the metal shell arranged outside the equipment, so that the purpose of connecting the third core with the inside and the outside of the equipment is realized, the welding is convenient, the welding flux is saved, and the operation difficulty of workers is reduced;

2. after the conducting wire is subjected to tin welding, the welding holes are only filled with the tin, so that the size of the welding positions is controlled, larger welding points are avoided, the conducting wire is welded from the inner side of the shell, the dimensional precision of the end part of the metal shell can be effectively controlled, and the appearance of the metal shell can be effectively guaranteed;

Detailed Description

The technical solution of the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

Referring to fig. 3, the outer housing of the power connector of the present embodiment has a structure 2 at an end thereof for facilitating welding. The structure 2 comprises a mounting base body 201 and a welding hole 202 on the mounting base body, wherein the mounting base body 201 is fixedly connected with the outer shell end face 101 of the power connector and extends along the direction perpendicular to the outer shell end face, and the welding hole 202 is lower than the outer wall 102 at the end part of the outer shell, namely, the welding hole 202 is closer to the axis of the outer shell than the outer wall 102 at the end part of the outer shell. The end of the welding hole 202 close to the axis of the outer shell extends in the direction away from the axis of the welding hole to form a retaining part 2021 for enhancing the pulling-out force of the lead in the axis direction of the outer shell after the lead is soldered, the retaining part may be a conical surface, a spherical surface or a paraboloid which is gradually expanded and complete in the circumferential direction, and the shape of the retaining part may be adjusted according to the needs in other embodiments of the present invention.

When connecting the outside power connector of equipment and the inside PCB board of equipment through the wire, be connected wire and PCB board earlier, then hang soldering tin with the silk of another tip of wire, then put into the welding hole of power connector shell body tip with this tip at anticreep portion place of wire, utilize the inboard of tin climbing effect follow casing of soldering tin to weld the wire, soldering tin can climb in the welding hole with wire and power connector's shell body firm in connection, not only make wire and power connector fully contact, realize the purpose of the inside and outside of third core jointing equipment, and convenient welding.
