Background Of The Invention
[0001] This invention is a continued-in-part of U.S Patent No. 5,336,108, wherein a cable
binder has pinching points for compressing and securing a cable. Although the pinching
points can have excellent effect in securing a cable, they may also hurt an outer
surface of a cable. This invention has been devised to improve this disadvantage.
Summary Of The Invention
[0002] This invention has an object to offer a microphone connector with features listed
below.
1. It has a cable binder consisting of a proximal portion, an intermediate portion
of a smaller diameter than the proximal portion, and a distal cone-shaped portion.
2. The intermediate portion and the distal portion of the cable binder are lengthwise
and equally divided into three or six elongate parts to function as pressing posts.
3. The intermediate portion has its inner surface contacting with the outer surface
of a cable deposited in the cable binder for pressing the cable tight.
4. The six elongate parts of the intermediate portion and the distal cone-shaped portion
have small force against expansion so that a lengthwise slot provided in the whole
length of the cable binder may be manually expanded to let a cable pushed into the
cable binder.

Detailed Description Of The Invention
[0008] A first embodiment of a female microphone connector in the present invention, as
shown in Figs. 1 - 4, comprises a connector member 1, a terminal carrier 2, a cable
binder 3 and a connector housing 5 as main components.
[0009] The connector member 1 is shaped cylindrical, having a proximal hand holding surface
portion 10 with two opposite grips 11, 11 for a user to grip this connector, an intermediate
smooth portion 14 and a distal male-threaded portion 15, an axially extending through
hole 13 for depositing the terminal carrier 2 and the cable binder 3 therein, a push
button 12 on the holding surface portion 10 and a front end 120 for assembling with
the connector housing 5. The intermediate smooth portion 14 is rather long and the
distal male-threaded portion 15 is rather short so that the threaded portion 15 can
mesh with a female-thread of the connector housing 5 with little force. Two opposite
axially extending grooves 16, 17 are provided in an inner surface of the hole 13 for
the terminal carrier 2 and the cable binder 3 to fit unrotatably straight in the hole
13.
[0010] The terminal carrier 2 is fitted in the through hole 13 of the connector member 1,
having a plate spring 20 fixed axially on its surface, two terminals 21, 21 to fit
in terminal holes 24, 24, a negative terminal 22, and the end of each terminal is
soldered with a wire of the cable 4.
[0011] The cable binder 3 shown in Figs. 3 and 4 has a proximal portion 30 with a groove
31, an intermediate portion 33 of a smaller diameter and longer than the proximal
portion 30, and a distal cone-shaped portion 34. The proximal portion 30 is shaped
as multi-gonal, preferably hexagonal or octagonal, with an inner circular surface
with smooth glossiness. The groove 31 is for receiving the minus terminal 22 of the
terminal carrier 2, and a reinforcing surface 32 is provided under the groove 31 to
add strength to the proximal portion 30 for prevention of splitting. The intermediate
portion 33 and the distal cone-shaped portion 34 are lengthwise and equally divided
into six elongate parts 35 or three elongate carts 35' (see Fig 5) to function as
pinching posts, and in addition a lengthwise slot 36, partly communicating with one
of the slots dividing the six parts 35, provided in the whole length of the cable
binder 3 so that the lengthwise slot 36 may be comparatively easy to be expanded for
inserting a cable through the slot 36 into the interior of the cable binder 3 with
less manual force, with the six elongate parts 35 having less force against expansion.
And the intermediate portion 33 has its inner surface possible to tightly contact
with the outer surface of a cable for acquiring tightness between the cable binder
3 and the cable 4. Therefore, after a cable 4 is deposited in the cable binder 3,
the connector housing 5 is screwed with the connector member 1, by engaging a female-thread
50 with the male thread 15, permitting a compressing ring 51 of the connector housing
5 press the distal cone-shaped portion 34 of the cable binder 3 as shown in Fig. 3,
with the cable 4 quite tightly bound therein and hardly pulled off as well.
1. A microphone connector comprising;
a connector member shaped cylindrical, having at least a proximal hand holding portion,
an intermediate smooth portion, a distal male-threaded portion to engage a female-threaded
portion of a connector housing, and an axially extending through hole for depositing
a terminal carrier or a plug and a cable pincher therein;
a terminal carrier shaped cylindrical to fit in the through hole of said connector
member, having a plate spring on an lengthwise surface, a number of terminal holes
for terminals to pass through, said terminals having one end soldered with wires of
a cable;
a connector housing having a female-threaded portion to engage the male-threaded portion
of the connector member and a compressing ring on an inner surface; and
a cable binder having a proximal portion with a groove, an intermediate portion extending
from the proximal portion, and a distal cone-shaped portion extending from the intermediate
portion, and said intermediate portion and said distal cone-shaped portion being divided
lengthwise into six equal elongate parts, said distal cone-shaped portion being compressed
by the compressing ring of said connector housing after said connector housing screws
with the connector member so that the three or six elongate parts may contact and
press the outer surface of a cable deposited in said cable binder, and thus the cable
can be bound tightly in said cable binder.
2. The microphone connector as claimed in Claim 1, wherein said proximal portion of said
cable pincher is shaped as multi-gonal on its outer surface.
