Description
Technical Field
The utility model relates to a SSMP multichannel is to inserting connector of LRM casing can pack into belongs to connector technical field.
Background
Along with the requirement of miniaturization development of the whole equipment, more and more connectors need to be integrated together, the whole volume is reduced, and the LRM module is produced at the same time. The LRM module is a high-low frequency mixed module, and is widely applied due to small volume and high reliability. SSMP family radio frequency coaxial connectors are the preferred connectors for LRM modules because of their small size, light weight, good shock resistance, wide operating frequency band, and the ability to allow for some axial and radial misalignment. However, the space between the SSMP connectors with high LRM module integration is very small, so the difficulty of manual operation is high during installation and disassembly, especially during disassembly, the connector is taken out by the friction force between the clamp and the connector shell after the reed of the LRM module is spread by the disassembly clamp, and many users pull the cable to take out the connector because the friction force is small, and the cable is easy to damage because the cable is generally a flexible thin cable and the axial tension born by the cable is small. Meanwhile, due to the fact that the SSMP connector in the LRM module is in multi-path plug-in mode, in order to guarantee plug-in place, springs are used in the SSMP connector to eliminate axial and radial gaps in machining, and plug-in place of the connector is guaranteed. When the spring is assembled in the SSMP connector, the spring needs to be compressed for a certain distance to obtain a certain elastic force, and the spring can be continuously compressed by applying a certain force after the connector is inserted in place. Because the spring is added into the SSMP connector, the shells of the connector cannot be integrally processed and can only be connected together again in a split interference fit mode, but because the SSMP connector has a small volume, the two shells are thin-walled parts, and the press-fit force of the two shells is weak. The two shells bear the elasticity of the spring after being pressed and assembled, when the press-assembling force of the two shells is close to the elasticity of the spring, the shells are stressed in the using process, the press-assembling force is weakened to separate the two shells, and the connector fails.
Under the background, an SSMP multi-way plug-in adapter is urgently needed to avoid the problems that the SSMP connector in the LRM module is difficult to mount and dismount, and the press-fit force of the shell is weak, which easily causes the failure of the connector.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a SSMP multichannel is to inserting connector that can pack into LRM casing to solve above-mentioned technical problem.
In order to realize the purpose, the utility model adopts the following technical scheme:
a SSMP multi-way opposite-inserting connector capable of being installed in an LRM shell comprises a spring, a shell A, a shell B and a shell C; the spring is fixed between the shell A and the shell C; the cable welding device is characterized in that soldering tin holes are formed in the shell A and the shell B, the soldering tin holes of the shell A and the shell B are aligned, a gap exists between the shell A and the shell B, the shell A, the shell B and a cable are welded together by soldering tin during welding of the cable, an installation and disassembly groove is formed in the shell B, and a metal sleeve for protecting the cable is arranged on the shell B.
Preferably: and the shell A and the shell B are provided with interference fit sections.
Preferably: the soldering tin hole on the shell A is smaller than the soldering tin hole on the shell B, so that the two soldering tin hole positions are easy to align during assembly, and meanwhile, after the soldering tin in the soldering tin hole on the shell A is full, the soldering tin is filled in a gap between the shell A and the shell B through the soldering tin hole on the shell B, and the shell A and the shell B are welded together.
Compared with the prior art, the utility model has the advantages of it is following: the utility model discloses SSMP connector can easily install and dismantle through installation and dismantlement anchor clamps in the LRM module, becomes the reliability of a whole improvement connector with the shell through the welding.

Detailed Description
The invention is explained in further detail below with reference to the figures and the embodiments.
A SSMP multi-way opposite-plug connector which can be installed in an LRM shell comprises a spring 1, a shell A2, a shell B3 and a shell C4; the spring 1 is fixed between the shell A2 and the shell C4; there are soldering tin hole 6 on shell A2 and the shell B3, and the soldering tin hole 6 of shell A2 and shell B3 aligns, has clearance 5 between shell A2 and the shell B3, and it is in the same place to weld shell A2, shell B3 and cable welding with soldering tin during the welding cable, be provided with installation and dismantlement recess 9 on the shell B3, be provided with the metal sleeve 8 of protection cable on the shell B3. The welding position is protected from welding failure caused by bending of the cable.
The interference fit sections 7 are arranged on the shell A2 and the shell B3, so that the connectors can be assembled into a whole before welding and the welding is convenient. The soldering tin hole on the shell A2 is smaller than the soldering tin hole on the shell B3, so that the two soldering tin hole positions are easy to align during assembly, and meanwhile, after the soldering tin of the soldering tin hole on the shell A2 is full, the soldering tin is filled in a gap between the shell A2 and the shell B3 through the soldering tin hole on the shell B3, and the shell A2 and the shell B3 are welded together. So that the cable, the casing a2 and the casing B3 are welded to form a whole.
The foregoing is a preferred embodiment of the present invention, and for those skilled in the art to understand the teaching of the present invention, the changes, modifications, replacements and variations to the embodiments will still fall within the protection scope of the present invention without departing from the principle and spirit of the present invention.
