Abstract

PURPOSE:To make the space of the back surface of a housing narrow, to prevent dust from entering thereinto and simplify assembling and disassemblimg by reducing the radius of curvature of a cable at the time of forming the cable. CONSTITUTION:A connector cover 2 fitted to a cable connector 3 is constituted of one piece of lower part cover 2a and two pieces of upper part covers 2b, and the connector cover 2 is assembled by connecting the rectangular hole 8 of the lower part cover 2a to the claw 9 of each of the upper part covers 2b. Apiece of round hole 7 is provided in each of the side walls of five planes of the connector cover 2, and a cable is inserted from either one of the round holes 7. Closing lids 10 are fitted into the round holes 7 in which the cable is not inserted, thereby preventing dust from entering thereinto.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a dustproof connector cover having a multidirectional hole, and more particularly to a cable drawing structure and a dustproof structure of a cable drawing port lid.

[0002]

2. Description of the Related Art Conventionally, a connector cover of this type has been used in a communication device housing to protect the connection of the wiring terminal portion of the cable connector by using a cable connector for connection inside or between housings. Provide an outlet to connect to the connector at the connection destination.

FIG. 4 is a perspective view showing an example of connecting connectors when a connector cover is used in a conventional communication device housing, and FIG. 5 is a perspective view showing an example of a conventional connector cover. .

On the backboard 5 in the communication device housing 1, a connector 4 having a large number of terminals and a connector cover 11 of the cable connector 3 wired to the connector constitute a mounting structure. The split lid cover 11a includes a pair of split lid covers 11a and clamp fittings 11b. The split lid cover 11a is provided with two surfaces inclined with respect to the connector insertion / removal direction, and a circular hole 7 through which the cable 6 can be pulled out. The connector cover is configured so that the cable 6 can be pulled out from either side depending on the connection destination.

As a document of this type of conventional technology, Japanese Utility Model Publication No. 55-102784 can be cited.

Further, in the case where the cable is not led out, the outlet is sealed with an elastic pressing piece, and a connector cover for preventing dust is described in Japanese Utility Model Laid-Open No. 55-69386.

[0007]

In the structure of this conventional connector cover, if the cable outlet has only two surfaces, when the connection destination is an irregular position or there are multiple connections in three or more directions, When performing cable forming in the communication device housing, the radius of curvature of the cable increases, and especially when the number of cables increases, a space for the amount of cable protrusion on the back side of the housing is required, and in order to prevent external force from being applied to the cable, Inevitably, there is a drawback that the housing becomes large.

Also, on the two surfaces of the cable outlet,
If the cable is used only through the hole on one side, the cable outlet on the other side remains open, so it is not possible to prevent dust from entering the connector cover and prevent dust. There is a drawback that hinders the effect.

Therefore, the present invention improves the drawbacks of the structure of the conventional connector cover described above, reduces the radius of curvature of the cable during cable forming to reduce the space on the back surface of the housing, and reduces dust. It is intended to prevent invasion and further facilitate assembly and disassembly.

[0010]

In order to solve the above problems, the present invention provides a connector having a large number of terminal portions and a connector cover of a cable connector wired to the terminal portions of the connector, wherein the connector cover is 1 It is composed of a lower cover and two upper covers, and the lower cover and the upper cover are connected by holes and claws to hold the connector in the connector wiring opening and to connect the cable to the five sides of the side wall. A dust-proof connector cover with a multidirectional hole having a through hole and a lid for closing the hole is constructed.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a perspective view showing a connection between connectors when a connector cover is used in a communication device housing showing an embodiment of the present invention.

In the connector 4 having a large number of terminal portions on the backboard 5 in the communication device housing 1 and the connector cover 2 of the cable connector 3 wired to the connector,
The connector cover 2 is formed by one lower cover 2a and two upper covers 2b, and this is attached to the cable connector 3.

The formed lower cover 2a and upper cover 2b
A round hole 7 for passing the cable 6 is formed on the five surfaces of the side wall except the opening for attaching to the cable connector 3.

FIG. 2 is a perspective view of a connector cover and a cable connector showing an embodiment of the present invention.

In the connector cover 2, the lower cover 2a for attaching the cable connector 3 has two rectangular holes 8 on each side wall, and a semicircular hole on the upper side of the four side walls. Four 7a are open.

The upper cover 2b has a claw 9 on each side wall for coupling with the rectangular hole 8 of the lower cover 2a, and also has semicircular holes 7a on two sides of the side wall. Two
A quarter circular hole 7b is formed in each side wall of the surface.

The connector cover 2 includes one lower cover 2
a and two upper covers 2b. When the rectangular hole 8 of the lower cover 2a and the claw 9 of the upper cover 2b are combined, one round hole 7 is formed on each of the five side walls of the connector cover 2. Each round hole 7 is provided with a closing lid 10 formed by a disc-shaped plate 10a and a plurality of curved and elastic plates 10b perpendicular thereto.

The sectional view of FIG. 3 shows a state in which the rectangular hole 8 of the lower cover 2a and the claw 9 of the upper cover 2b are joined together.

If there are round holes 7 provided on the five sides of the side wall of the connector cover 2, the mating connector of the connector on the backboard 5 inside the communication device housing 1 is in an irregular position or a cable in three or more directions. Even if there are multiple connections, the radius of curvature of the cable 6 can be reduced by using the round hole 7 at the shortest position when performing cable forming, and the amount of cable protrusion to the rear side of the case is small and the case is small. You can make your body smaller.

Further, when the round holes 7 on the five sides of the side wall of the connector cover 2 are not used, the intrusion of dust can be prevented by attaching the closing lid 10 with one touch.

[0022]

As described above, in the dustproof connector cover with multidirectional holes according to the present invention, when there are holes through which the cables are inserted on the five sides of the side wall except for the cable connector wiring opening, the back inside the communication device housing is covered. Even if there is an irregular position of the mating connector on the board or a cable multi-connection in three or more directions, the radius of curvature of the cable can be reduced by using the hole through which the cable is placed at the shortest position when performing cable forming. It can be made smaller, and the space on the back of the housing can be made smaller.

Further, in the place where the hole for passing the cable is not used on the five sides of the side wall, a closing lid is attached to prevent dust from entering.

Further, the connector cover of the present invention comprises one lower cover and two upper covers, and the lower cover and the upper cover are connected by the holes and the claws.
This has the effect of facilitating assembly and disassembly.
