Abstract

PROBLEM TO BE SOLVED: To accurately detect the draw of a fixture by elastically urging a rod-like part and a movable electrode in the fixture to a casing fixing part by an urging means so that the rod-like part is urged to the separation side and the movable electrode is urged to the separation side from a fixed electrode. SOLUTION: When a fixing pin 3 is inserted and locked, a coil spring 31 is depressed to a compression side by the conical taper part 3b of the pin 3. Thereby an electrode piece 31a is moved to the inserting direction of the pin 3 and brought into contact with an electrode 6a formed on a printed board 6 through an aperture 44 formed on the lower surface of a fixture unit 4. Since the piece 31a is elastically supported by a part extended from the upper end part of the spring 31, the piece 31a is elastically deformed from the contact state with the electrode 6a by inserting the rod-like part 3A, turned to a state accumulating elastic urging force oriented to the electrode 6a and surely brought into contact with the electrode 6a.

2. Description of the Related Art Such an anti-theft device is used by being attached to an anti-theft object. When the anti-theft device is illegally removed from the anti-theft object, an alarm is output and the anti-theft object is illegally handled. It is to inform that it is being done. In order to attach the anti-theft device to the anti-theft object, for example, when the anti-theft object is cloth, the rod-shaped part of the attachment is inserted into the housing of the anti-theft device while penetrating the cloth and connected. Attach by The anti-theft device attached to the anti-theft object outputs an alarm as described above when the mounting device is illegally pulled out and the anti-theft device is incorrectly removed from the anti-theft object. Is provided in the housing of the anti-theft device. Specifically, a movable electrode that is pushed and moved to the fixed electrode side is provided in the housing as the rod-shaped portion of the mounting tool is inserted into the housing against the urging force of the urging means. When the tool is inserted into the housing, the movable electrode and the fixed electrode are in contact. Then, by switching from a state in which the movable electrode and the fixed electrode are in contact to a state in which the movable electrode and the fixed electrode are separated by the urging force of the urging means, it is detected that the fixture has been pulled out.

However, since a biasing force acts on the movable electrode on the side away from the fixed electrode, if the movable electrode and the fixed electrode are simply brought into contact with each other only by pushing the rod portion, the movable electrode is moved by vibration of the rod portion or the like. In some cases, the electrode and the fixed electrode are separated from each other, and a false alarm is issued. Conventionally, in order to deal with this, as disclosed in JP-A-7-65257, that is, as shown in FIG. 15, the metallic movable electrode 100 is biased toward the side away from the fixed electrode 101. The coil spring 102 is provided so as to urge the movable electrode 100 against the housing-side fixed portion, and when the rod-shaped portion 3A of the fixture 3 is inserted,
A contact coil spring 103, which is compressed by the pushing operation force of the rod-shaped portion 3A and urges the movable electrode 100 and the fixed electrode 101 toward the contact side, is a contacted member where the movable electrode 100 and the rod-shaped portion 3A come into contact. 104 and the coil spring 102 and the coil spring 1
03 constituted urging means for urging the rod portion 3A and the movable electrode 100.

However, in the above-described conventional configuration, the contact coil spring 103 also has a function of urging the rod-shaped portion 3A to the detaching side, so that the rod-shaped portion 3A is moved to the detaching side. In general, the force acting on the coil spring 103 so that it can be pushed out strongly is also large. Therefore, in particular, when used for a long period of time, permanent distortion occurs in the coil spring, contact between the movable electrode and the fixed electrode is incompletely maintained, and it may be erroneously detected that the attachment has been pulled out. there were. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to make it possible to accurately detect withdrawal of a fixture.

According to the first aspect of the present invention, the urging means elastically urges the rod-shaped portion and the movable electrode of the fixture with respect to the housing-side fixed portion, so that the rod-shaped portion is formed. For the movable electrode, and for the movable electrode in a direction away from the fixed electrode. When the rod is inserted into the housing against the urging means, the movable electrode is pushed and moved to come into contact with the fixed electrode. When the rod portion is further inserted from that state, the movable electrode elastically deforms and stores an elastic biasing force toward the fixed electrode. Even when the rod portion mechanically vibrates, the movable electrode is fixed to the movable electrode by the elastic biasing force. The electrodes are properly maintained in contact. Although the elastic deformation of the movable electrode occurs due to the insertion of the rod-shaped portion, the degree of the elastic deformation, that is, the strength of the elastic urging force for maintaining the movable electrode and the fixed electrode in contact with each other, is not sufficient. It is possible to set an appropriate elastic urging force separately from the urging force of the urging means that requires a proper urging force. Therefore, even when permanent setting occurs in the urging means for elastically urging the rod portion toward the detached side, the movable electrode and the fixed electrode can be kept in accurate contact with each other. Thus, even when the anti-theft device is used for a long time, it is possible to accurately detect the removal of the attachment.

In addition, with the configuration according to the second aspect, as the rod-shaped portion is inserted, the rod-shaped portion pushes the operated member, and the urging means is attached to the operated member. Act. Therefore, the pushing operation force and the urging force opposing the pushing force are required between the rod-shaped portion and the urging means, as compared with the case where the rod-shaped portion is pushed in contact with the urging means. Design restrictions such as dimensions and shapes are relaxed, which can be advantageous in terms of practical production. Furthermore, since the movable electrode is supported by the operated member on which the push operation force of the rod portion is applied, the movable electrode can be accurately moved with the insertion of the rod portion, and the movable electrode that elastically deforms can be properly supported, Switching between contact and contact between the movable electrode and the fixed electrode can be accurately performed.

Further, by providing the structure according to the third aspect, the biasing means is constituted by a coil spring, and the movable electrode is formed in a state in which the end of the coil spring on the rod-shaped portion side extends laterally. Is formed. Therefore, the urging means and the movable electrode which need to have elasticity are integrally formed,
The configuration can be simplified.

When the mounting pin 3 is inserted into the pin insertion hole 40, the diameter of the arc-shaped hole 42b is formed to be smaller than the maximum diameter of the tapered tip portion of the mounting pin 3, so that the diameter is reduced. When the mounting pin 3 is further inserted, the distal end portion of the lock shape engages with the arcuate hole portion 42b of the engagement hole 42, and the direction in which the free end side end 41b approaches the base end side 41a and the lock spring 41 A force acts in the direction of pushing down, and the lock spring 41 swings along the tapered portion 43a shown in FIG.

When the anti-theft device 1 is activated and the mounting pin 3 is forcibly pulled out with a strong force without performing a normal release operation, the detection switch S is turned off. As a result, the switch input circuit 23 outputs a removal detection signal to the signal processing circuit 25. When the removal detection signal is input, the signal processing circuit 25
Is turned on, and the semiconductor switch 29c is turned on. Thus, the oscillation circuit 26 and the counter 27 start operating, and the counter outputs a pulse signal of the set repetition period to the signal processing circuit 25.
