ABSTRACT:
BACKGROUND OF THE INVENTION
(a) Field of the Invention
The present invention relates to an improvement in the SMA (SUB-MINIATURE) connector structure.
(b) Description of the Prior Art
With the advance of technology, there are demands for compact and quality products. Quick assembly and low costs are objects of developing new products, for example, manufacturers of coaxial cable connectors focus on developing connectors that are quick to assembly and inexpensive to manufacture. With reference to
FIG. 1
, the; middle portion of a T-shaped connector
11
is provided with a receiving hole
111
′. An exit
113
′ at the bottom portion of the receiving hole
111
′ has a diameter smaller than an entrance
112
′ thereof. The receiving hole
111
′ is sized to receive an insulation member
14
′ having a wire hole
141
′ in the middle portion thereof. a lateral annular edge of the insulation member
14
′ abuts against an annular edge wall of the exit
113
′ . Upper and lower opposed injection holes
15
′ are formed in the T-shaped connector
11
′ at positions corresponding to the lateral edge of the insulation member
14
′ in the receiving hole
111
′. A plastic substance
118
′ is injected via the injection hole
15
′ to adhere the insulation member
14
′ firmly in the receiving hole
111
′. With reference to
FIG. 2
, the middle portion of a T-shaped connector
11
′ is provided with a receiving hole
111
′. The rear end of the inner edge of the interior of the receiving hole
111
′ is provided with an insert ring wall
116
′ that has a diameter smaller than that of the receiving hole
111
′ and that projects inwardly The rear end of the insert ring wall
116
′ is pre-formed with an insert hole
117
′. An insulation member
14
′ having a wire hole
141
′ in the middle portion thereof is disposed in the receiving hole
111
′. An insert ring member
12
is retained on an outer edge face projecting from he insulation member
14
′, and is inserted into the insert hole
117
′ in the rear end of ′ the receiving hole′
111
′ to thereby retain the insulation member
14
′ in the receiving hole
111
′. There are drawbacks with these two types of assembly. First, forming two injection holes in the T-shaped connector and injecting a plastic substance to secure the insulation member is not only laborious and time-consuming, the assembly efficiency is low. As for the other method of assembly, it is also time-consuming and laborious to drill an insert hole in the receiving hole in one side of the T-shaped connector. Besides, since it requires secondary processing, it is not economical. Furthermore, whether hole drilling or rear insertion is adopted, the connector is not pleasing in appearance.
SUMMARY OF THE INVENTION
The present invention relates to an improvement in the SMA (SUB-MINIATURE) connector structure.
It is the primary object of the present invention to provide an improved SMA (SUB-MINIATURE) connector structure, particularly one that utilizes an insert ring member inserted into a receiving hole in a T-shaped connector to quickly insert and retain an insulation member in the T-shaped connector to thereby achieve a connector that has advantages of quick assembly and reduced costs.
The foregoing object and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts. Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
