ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an insertion and withdrawal connector apparatus received in a connector receiving body in such a manner that a plurality of connectors and a plurality of mating connectors can be mutually engaged with and separated from each other, and integrally combining each of the connectors so as to be used for inserting into and withdrawing from each of the mating connectors. Further, the invention relates to a structure for remote controlling an engagement and separation of the insertion and withdrawal apparatus. Still further, the invention relates to a structure for mutually connecting connecting frame blocks used for the insertion and withdrawal connector apparatus or the like.
Firstly, a first conventional art will be described below. The insertion and withdrawal connector apparatus is constituted, for example, by a plurality of connectors connected to a plurality of cables for transmitting and receiving a predetermined signal by means of mutually connecting a multiplicity of cables used for wiring of a computer to a multiplicity of mating cables one by one, and a plurality of mating connectors connected to a plurality of mating cables.
In this kind of insertion and withdrawal connector apparatus, a plurality of connectors integrally holding a predetermined number of cables and a plurality of mating connectors are prepared, and a plurality of connectors and a plurality of mating connectors are inserted into and withdrawn from one pair by one pair. However, there is a risk of injuring each of the cables and each of the connectors due to decrease of a working efficiency and a load incurred when working is performed.
An insertion and withdrawal connector apparatus in accordance with the first conventional art has, as shown in
FIGS. 1 and 2
, a connector receiving body
1
for receiving a plurality of connectors
10
in such a manner as to be insertable and withdrawable in an inserting direction I and a withdrawing direction II.
The connector receiving body
1
has a pair of frames
3
arranged in parallel to each other, a pair of frame blocks
4
mutually, integrally holding each of both end surfaces in a longitudinal direction of a pair of frames
3
, and a plurality of partition members
5
which partition the longitudinal distance between a pair of frame blocks
4
so as to separate it into predetermined intervals and which are attached to a pair of frames
3
.
A pair of frame blocks
4
and a pair of frames
3
are integrally held by screws
6
. In the connector receiving body
1
, a plurality of space portions partitioned by each of the frames
3
, each of the frame blocks
4
and each of the partition members
5
become a plurality of receiving chambers
7
for receiving a plurality of connectors
10
and a plurality of mating connectors
20
. In each of a plurality of receiving chambers
7
, a plurality of connectors
10
and a plurality of mating connectors
20
are received in an inserting and withdrawing direction one to one.
Further, in the connector receiving body
1
, a plurality of space portions partitioned by a pair of frames
3
and each of the partition members
5
become a plurality of receiving chambers
7
for receiving a plurality of connectors
10
and a plurality of mating connectors
20
.
A plurality of cables
15
are connected to each of the connectors
10
, and a pair of projections
18
for locking in one-touch a pair of frames
3
of the connector receiving body
1
and for driving a slider are provided on both of upper and lower surfaces of each of the connectors
10
. A pair of projections
19
for locking in one-touch a pair of frames
3
of the connector receiving body
1
and for driving a slider are provided on both of upper and lower surfaces of each of the mating connectors
20
.
Incidentally, a plurality of conductive contacts (not shown) are incorporated in each of the connectors
10
, and these contacts are connected to a plurality of cables
15
one to one. Further, a plurality of conductive mating contacts
21
such as pin contacts are attached to each of the mating connectors
20
in such a manner as to be in contact with the above contacts, and these mating contacts
21
are connected to contacts of apparatus side connectors held by a device holding the connector apparatus.
Further, in each of the connectors
10
, an engagement portion
10
b
is provided at a front end portion of the inserting direction I side. A plurality of insertion holes capable of inserting each of the mating contacts
21
are formed in each of the engagement portion
10
b.
Each of a pair of frames
3
has a frame plate portion
3
a
having an elongate plate shape, and a pair of guide portions
3
b
formed in a longitudinal direction at both sides of the inserting and withdrawing directions I and II of each of the connectors
10
, that is, at both edge portions which are a pair of sides parallel to a longitudinal direction of each of the frame plate portions
3
a
. Each of the guide portions
3
b
is a portion which extends to an upper portion of each of the frame plate portions
3
a
from each of the both edge portions in the longitudinal direction of each of the frame plate portions
3
a
and which is curved in parallel to the frame plate portion
3
a.
Further, in each of the frame plate portions
3
a
, there are formed a plurality of projection moving windows
25
long extending in the inserting and withdrawing directions I and II from an edge end of a side inserting each of the connectors
10
. A locking spring piece
26
which has a substantially L shape and whose one end is connected to the frame plate portion
3
a
so as to extend to the inserting and withdrawing directions I and II is formed in each of the projection moving windows
25
. The locking spring piece
26
has the same thickness as a thickness of the frame plate portion
3
a
, and has an elastic force in a direction perpendicular to the inserting and withdrawing directions I and II.
Since the projection
18
of the connector
10
moves in the inserting direction I along an inner side of the projection moving window
25
and a hook portion
26
a
formed in a front end of the locking spring piece
26
is pushes by the projection
18
when the connector
10
is inserted into the receiving chamber
7
, the locking spring piece
26
pushes the connector
10
into the inner part of the receiving chamber
7
while being flexed. When the connector
10
is pushed into the inner part of the receiving chamber
7
, the locking spring piece
26
returns to an original state. Under this state, the hook portion
26
a
prevents the projection
18
from moving in the withdrawing direction II. Since the operation is performed in the above manner, the connector
10
can be locked in one-touch within the receiving chamber
7
.
Further, a plurality of projection windows
55
long extending to the inserting and withdrawing directions I and II from the edge end opposite to the edge end in the side inserting each of the connectors
10
are formed in the frame plate portion
3
a
. The projection
19
of each of the mating connectors
20
is fitted to the inner side of each of the projection windows
25
. Under this state, since each of the projections
19
is fitted to a pair of positions of each of the projection windows
55
, each of the mating connectors
20
is held within the receiving chamber
7
.
Incidentally, each of the projection moving windows
25
and each of the projection window
55
are disposed in a positional relation in which they are aligned in a widthwise direction (corresponding to the inserting and withdrawing directions I and II) and a longitudinal direction of the frame plate portion
3
a
, and are positioned such that a pair of them are positioned in each of the receiving chambers
7
.
Under a state that each of the connectors
10
and each of the mating connectors
20
are received in the connector receiving chamber
1
, each of the projections
18
and each of the projections
19
project above the frame plate portion
3
a
. And, each
