ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a microphone connector, particularly to one capable to prevent the microphone connector from randomly separating from a microphone, and really keep the microphone from falling off the connector to cause damage to the microphone.
BACKGROUND OF THE INVENTION
A first conventional microphone connector shown in
FIG. 1
includes a body
1
, a terminal base
10
provided in the body
1
for receiving terminals
100
, an elastic hook
11
combined on the body
1
, a stop annular wall
12
formed integral with the body
1
, male threads
13
formed on the stop annular wall
12
, a constrict ring
14
having female threads
140
to engage with the male threads
13
to combine with the body
1
, and a rear body
15
having female threads
150
to engage with the body
1
and a cable constrictor
16
for constrict a cable. The constrict ring
14
can prevent the elastic hook
11
from pressed.
However, the first conventional microphone connector has the body
1
provided with the stop annular wall
12
, which may form a gap (d) between the connector and a microphone
17
after the microphone
17
is connected with the connector. This gap may hamper mutual tight combination of the both so that the microphone may sway owing to the gap (d), and subsequently fall off the connector to be damaged. Further the gap (d) forces the combined state of the microphone and the connector slant to look like untidy
A second conventional microphone connector shown in
FIG. 2
includes a body
2
, a terminal base
20
for receiving terminals
200
, an elastic hook
21
provided on the body
2
, male threads
23
, a constrict ring
24
having female threads
240
and a sloping surface
241
extending rearward from the male threads
240
, and an inner annular surface
242
of a larger diameter extending rearward from the sloping surface
241
. Then the constrict ring
24
threadably engages with the body
2
with the elastic hook
21
positioned in the constrict ring
24
so that the constrict ring
24
may move forward after a microphone is combined with the connector with the inner annular surface
242
forcing the elastic hook
21
tightly hook the microphone
17
. Then the microphone
17
may be closely combined with the connector. In case the constrict ring
24
is moved rearward, the female threads
240
of the constrict ring
24
presses the elastic hook
21
to force the microphone
17
separate from the connector, and a rear fixing base
25
of the connector can be used for locking the connector on a flat surface of something like a table.
The second conventional microphone connector can keep a microphone in a stable condition, with the constrict ring
24
, but it is more suitable for a fix-style microphone, and its elastic hook
21
may soon lose its elasticity by frequent use, possibly causing the microphone to fall off the connector.
SUMMARY OF THE INVENTION
This invention has been devised to offer a microphone connector improved in the above-mentioned disadvantages. The microphone connector has the following features.
1. It uses a rotatable constrict ring rotated to move forward to constrict a microphone tightly and keeping the elastic hook from pressed and subsequently preventing the microphone from falling off the connector.
2. It has a body, a terminal base, an elastic hook, a guide annular wall and male threads provided in the body, and a compress ring having a lateral gap and combined with the guide annular wall in a definite direction.
