Description

SMA connects for antenna

Technical Field

The utility model belongs to the technical field of the antenna and specifically relates to an equipment is convenient, SMA for antenna that packaging efficiency is high connects.

Background

Sma (small a type), is a microwave high-frequency connector; the conventional SMA joint, as shown in fig. 1-2, generally includes a core wire 1, a tail pipe 2, a thimble 3, a shell 4 and an insulating ring 5, and is assembled by: firstly insert tail takeover 2 with heart yearn 1 and its copper wire 11 wears out tail takeover 2, then establish the insulating ring 5 on copper wire 11 overlaps, insert in thimble 3 with copper wire 11 again, set up shell 4 on the subassembly of above-mentioned equipment completion at last, accomplish the equipment, however this kind of SMA connects in the assembling process, and heart yearn 1, tail takeover 2, the subassembly that thimble 3 and insulating ring 5 combination formed can not be stacked, need put neatly, otherwise the gasket can fall, seriously influences production efficiency.

Therefore, the SMA connector for the antenna is convenient to assemble and high in assembling efficiency.

Disclosure of Invention

The utility model discloses the purpose is in order to overcome prior art not enough and provide an equipment convenience, SMA connects for antenna that packaging efficiency is high.

In order to achieve the above purpose, the utility model adopts the technical scheme that: an SMA connector for an antenna comprises a core wire, a tail connecting pipe, a thimble and a shell; the core wire is inserted into the tail connecting pipe, and the copper wire of the core wire extends out of the other end of the tail connecting pipe; the center of the lower end face of the thimble is provided with a compression ring, and the copper wire of the core wire penetrates through the compression ring to be inserted into the thimble and is compressed and fixed by the compression ring; the shell is sleeved on the tail connecting pipe and the ejector pin so as to relatively fix the tail connecting pipe and the ejector pin.

Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:

SMA connects for antenna pass through the lower tip of thimble sets up the clamping ring, the copper wire of heart yearn passes in the clamping ring inserts the thimble to it is fixed to be compressed tightly by the clamping ring, need not to set up the sealing ring, simple structure, and can stack, has improved production efficiency.

The technical scheme of the utility model is further explained by combining the attached drawings as follows:

FIG. 1 is an exploded view of a prior art SMA connector;

FIG. 2 is an enlarged schematic view of a prior art SMA connector;

fig. 3 is an exploded view of an SMA contact for an antenna according to the present invention;

fig. 4 is an enlarged schematic view of an SMA contact for an antenna according to the present invention;

wherein: 1. a core wire; 2. a tail pipe connection; 3. a thimble; 4. a housing; 5. an insulating ring; 11. a copper wire; 31. and (5) pressing a ring.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments; based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 3-4, the SMA connector for antenna of the present invention includes a core wire 1, a tail pipe 2, a thimble 3 and a housing 4; the core wire 1 is inserted into the tail connecting pipe 2, and a copper wire 11 of the core wire extends out of the other end of the tail connecting pipe 2; a pressing ring 31 is arranged at the central part of the lower end face of the thimble 3, and the copper wire 11 of the core wire 1 passes through the pressing ring 31 and is inserted into the thimble 3 and is pressed and fixed by the pressing ring 31; the shell 4 is sleeved on the tail connecting pipe 2 and the ejector pin 3 so as to relatively fix the tail connecting pipe 2 and the ejector pin 3.

During assembly, the core wire 1 is firstly inserted into the tail connection pipe 2, the copper wire 11 extends out of the other end of the tail connection pipe 2, then the copper wire 11 penetrates through the pressing ring 31 of the thimble 3 and is inserted into the thimble 3, and finally the shell 4 is sleeved on the tail connection pipe 2 and the thimble 3, so that the assembly is completed.

SMA connects for antenna pass through the lower tip of thimble 3 is equipped with clamping ring 31, copper wire 11 of heart yearn 1 passes in clamping ring 31 inserts thimble 3 to it is fixed to be compressed tightly by clamping ring 31, need not to set up the sealing ring, simple structure, and can stack, has improved production efficiency.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and the protection scope of the present invention can not be limited thereby, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.

Claims
