ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a cable connector, more particularly to a cable fixture of a coaxial connector that prevents the cable from being detached or broken while unplugging the connector.
2. Description of the Related Art
In a general wireless network device, a certain distance is kept between the transmitting circuit and the receiving circuit to avoid the interference between the transmitting signal and the receiving signal that may deteriorate the signals, and a coaxial cable is used for connecting the transmitting circuit and the receiving circuit.
Please refer to
FIG. 1
, A connector
11
disposed on both ends of an coaxial cable
10
is individually plugged into the sockets of the transmission circuit and the receiving circuit, such that the transmission circuit and the receiving circuit are electrically coupled, and said connector
11
comprises a metal housing
13
, an insulator
15
, and a contact terminal
16
at one end of the coaxial cable
10
, wherein said metal housing
13
has a hollow cylindrical section
131
; said cylindrical section
131
at one end has a covering section
133
; said covering section
133
has an area larger than that of the cylindrical section
131
; a wing section
135
is extended outwardly from each side of the metal housing
13
; said covering section
133
has a wrapping section
136
corresponding to another end of the cylindrical section
131
; said wrapping section has a plurality of plates symmetrically arranged and disposed thereon; said insulator
15
at a position proximate the center has a penetrating hole
151
for installing the contact terminal
16
, and at one end having an open groove
153
for accommodating the coaxial cable
10
; said insulator
15
is disposed in said cylindrical section
131
such that when said coaxial cable
10
and contact terminal
16
are installed onto the open groove
153
and the penetrating hole
151
respectively, said covering section
133
is bendable to cover the covering section
133
on the top surface of the cylindrical section
131
, while the wrapping section
136
covers the coaxial cable
10
, and then a wing section
135
of the covering section
133
is bent downward, and the plate member of the wrapping section
136
is bent downward to fix the covering section
133
onto the cylindrical section
131
, and in the meantime, the plate of the wrapping section
136
wraps the coaxial cable
10
and fixes the coaxial cable onto the connector
11
.
However, when the connector
11
is unplugged, the stress pulling the connector
11
may easily cause the coaxial cable to separate from the connector
11
or break between the plates of the wrapping section
136
, since the coaxial cable
10
only relies on the plates of the wrapping section
136
to wrap the cable.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a cable fixture for a coaxial connector, and the fixture comprises a metal housing, said housing having a hollow cylindrical section, and said cylindrical section at one end has an external cover and a circular arc lower cover at the other end; the area of said external cover is larger than that of said lower cover such that when an insulator is placed in the cylindrical section, and a cable with terminals are placed on the lower cover, the external cover is bendable to cover cylindrical section, while the upper section covering the cable. Then, wing sections extended from each side of the external cover is bent downward to press on the upper cover and fix the external cover onto the cylindrical section, and fix the upper cover onto the lower cover. By the arrangement of tightly wrapping the cable with the upper and lower covers, the cable will not come off from the upper cover or break when the connector is unplugged.
