DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a current-carrying connector for an electric lock.

[0002]

2. Description of the Related Art Recently, electric locks have been installed on entrance doors and the like,
An electric locking / unlocking system has been developed in which the electric lock can be applied and unlocked by an electric lock operating device installed in a room. FIG. 5 shows an example of the configuration of such an electric locking / unlocking system. A secret electric lock operation device 200 is installed on a gate of an entrance (not shown) to which the electric lock unit 100 is attached, and is installed in a dwelling unit. Installed an electric lock controller 300 capable of setting and registering a personal identification number, connecting these with signal lines L100 and L101,
The electric lock controller 300 is connected to a power transformer 400 for stepping down an AC power supply.

In such an electric locking / unlocking system, if a four-digit password is set and registered in advance by a password setting switch (rotary switch) 300a on the side of the electric lock controller 300, the cover 200b of the secretary lock operating device 200 can be used. Is opened and the ten key 200a is operated to input a password, the input password is compared with the password registered and set on the electric lock controller 300 side, and when the coincidence is determined, the unlocking operation is performed. When the key 200c is operated, an unlock command signal is transmitted from the operation device 200 to the electric lock controller 300 via the energization control line L100, and the electric lock controller 30 is operated.
At 0, an unlocking command signal is received, an unlocking signal can be output to the electric lock unit 100 side via the energization control line L100 to unlock, and a lock state detection signal output from the electric lock unit 100 Is transmitted to the side of the electric lock controller 300 installed in the dwelling unit via the power supply control line L101, and is displayed by driving the lock indicator light 300c or the unlock indicator light 300d. Reference numeral 200d denotes a lock switch provided on the secret lock operation device 200 side.

On the other hand, separately from the secret electric lock operating device 200, an unlocking / unlocking operation key 300e provided in the electric lock control device 300 and an operation key 500a of an electric lock display operating device 500 added to the electric lock control device 300 are provided. Can be operated to unlock and open the electric lock unit 100, and the locking indicator 50 can be operated on the operation device 500 side.
0b, an unlocking indicator light 500c can be used to display the lock state, the remote control of the electric lock unit 100 is possible while staying in the dwelling unit, and the secret electric lock operation is performed when the resident comes home. By operating the device 200, the electric lock unit 100 can be unlocked immediately.

[0005]

However, in such an electric locking / unlocking system, an electric lock controller 300 installed indoors is provided on the door side where the electric lock unit 100 is incorporated.
Since the power is supplied from the side and remote control is performed, it is necessary to pass the power supply control line L101 from the indoor side to the door side through the gap between the door and the gate post on the door side incorporating the electric lock unit 100. there were.

For this reason, in the conventional electric locking / unlocking system, in order to protect the power supply control line L101 (see FIG. 5) laid through the gap 800 between the door and the gate post, a hole as shown in FIGS. One set of connection fittings 400, 400 each having 400a, 400a, is attached to both the end of the door 500 and the end of the gate 600, and a current control line connected between the connection fittings 400, 400. L101
A structure in which a metal wire (see FIG. 5) is protected by being inserted into a spring cord 700 formed by spirally winding a metal wire is used. The connection fittings 400, 4
As shown in FIG. 6, the holes 400a, 400a formed in the hole 00 can accommodate the bent spring cord 700 when the door 500 is closed.

However, such connection fittings 40
0,400 must be formed by forming recesses 900,900 by hollowing out the end face of the door 500 and the mounting position of the gate post 600, and then mounting them by screwing, etc., which makes the work during construction particularly troublesome. Met.

An object of the present invention, proposed in view of the above circumstances, is to provide an electric lock connecting device for an electric lock which can be easily mounted and can surely protect an energizing control line.

[0009]

According to the present invention, there is provided a current-carrying connector for an electric lock, which is provided with a first connection cover screwed to a door on which the electric lock is arranged, and a floor. A second connection cover, which is covered with an opening window of a wiring box fixed to the wiring pipe raised from the surface and screwed,
They are connected by a flexible protective tube, and have a structure in which an energization control line is inserted through the tube.

In the electric connecting device for an electric lock according to the present invention, the flexible protective tube is a spring cord formed by spirally winding a metal wire.

[0011]

According to the current-carrying connector of the present invention, the current-carrying control line derived from the electric lock is inserted through the flexible protective tube from the first connection cover and pulled out to the second connection cover.
The energization control lines led out of the room are drawn out of a wiring box fixed to the wiring tube, and the respective energization control lines are connected to each other as shown in FIG.
After the interconnections are connected within the opening window of the wiring box as shown in (1), the first connection cover is screwed into place on the indoor side of the gate post or wall, and the second connection cover is screwed into the wiring box. It can be easily installed without forming a hollow part on the door, gate post or wall surface.

[0012] Further, the current-carrying control line bridged and connected between the door and the gate post or the wall surface is protected by the flexible tube, so that it is not directly damaged and has a structure resistant to bending.

[0013]

An embodiment of the present invention will be described below with reference to the drawings. 1 to 4 show an example of mounting the current-carrying connector of the present invention. The first connection cover 1 is fastened by screwing a screw 8 from a screw hole 1e below the door 5 on the indoor side, and the second connection cover 2 is attached to the door 5 so that the door 5 can be opened and closed by a hinge 13. The screw 8 is screwed into the wiring box 9 attached to the upper end of the wiring tube 6 rising vertically from the floor surface 11 on the indoor surface side of the wall surface 12 through the screw hole 2f with the mounting plate 10 interposed. Have been.

First connection cover 1 and second connection cover 2
Is a flexible protective tube 3 as shown in FIGS.
