ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a connector, and more particularly to a low profile cable end connector for high frequency application.
2. Description of the Related Art
An RF (Radio Frequency) cable end connector is used for connecting a cable with an electronic device for transmitting RF signal. Such a conventional RF cable end connector is, for example, disclosed in U.S. Pat. Nos. 6,340,312 B1 and 6,305,980 B2. Both patents are invented by the same inventor of the present invention. Referring to
FIGS. 8 and 9
, which are similar to
FIGS. 6 and 7
of the U.S. Pat. No. 6,340,312 patent, the cable end connector includes a dielectric housing
10
′, a terminal
30
′ received in the housing
10
′, a shell
50
′ enclosing the housing
10
′, and a retainer
60
′ attached to the shell
50
′ for holding a coaxial cable
70
therein. The terminal
30
′ includes a pair of mating portions
33
′ and a planar tail portion
31
′ extending rearwardly to contact with an inner conductor
71
of the coaxial cable
70
. The shell
50
′ has a pair of arms
513
′ for accommodating the tail portion
31
′ of the terminal
30
′ therebetween. A pair of sealing tabs
5133
′ extend from free ends of the arms
513
′ for clamping a braiding layer
73
of the coaxial cable
70
.
However, the cable end connector with such a design regarding the connection of the terminal
30
′ with the inner conductor
71
of the cable
70
cannot meet a higher operating frequency requirement, such as 6 GHz. To meet the high frequency requirement, the solder joint between the terminal
30
′ and the inner conductor
71
should be located as close as possible to the mating portion
33
′ of the terminal
30
′, and the terminal
30
′ and the inner conductor
71
should be minimized in size. Furthermore, particularly referring to
FIG. 9
, the retainer
60
′ of the cable end connector has a pair of locking tabs
63
′, a pair of braiding crimps
65
′ and a strain relief
69
′ respectively engaging with different portions of the cable
70
and the shell
50
′, which results in an increased lengthwise dimension and increased production cost of the cable end connector. In addition, the height of cable end connector is also required to be reduced to comply with the miniaturization trend.
Hence, a low profile cable end connector for high operating frequency application is required to overcome the disadvantages of the related art.
BRIEF SUMMARY OF THE INVENTION
A main object of the present invention is to provide a cable end connector for high operating frequency application.
Another object is to provide a cable end connector having a low profile and a reduced lengthwise dimension.
A cable end connector according to the present invention comprises a dielectric housing, a terminal received in the housing, a unitarily formed shell, and a retainer attached to the shell for holding a coaxial cable therein.
The housing includes a base portion and a tubular portion supported on the base portion. The terminal has a bottom portion and a pair of contacting wings extending upwardly from the bottom portion, wherein an inner conductor of a coaxial cable is soldered onto a lower surface of the bottom portion of the housing. The shell includes a planar portion attached to a bottom face of the base portion, and a trunk portion connected to the planar portion and enclosing the tubular portion of the housing. The trunk portion includes a pair of arms extending rearwardly to engage with a braiding layer of the coaxial cable. The retainer includes a pair of locking tabs respectively depending downwardly from opposite sides of the retainer for retaining the arms to the planar portion of the shell, and a contacting portion depressed from a top wall of the retainer to engage with the braiding layer of the coaxial cable. The locking tabs of the retainer achieves two functions: keeping the integrity of the cable end connector and grounding the braiding layer of the coaxial cable.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
