Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a reed switch attachment structure that does not cause characteristic deterioration.

[0002]

[Prior art]

 3A and 3B are views showing a crime prevention switch in which a reed switch is incorporated by a conventional attachment structure. FIG. 3A is a plan view, FIG. 3B is a partially broken front view, and FIG. 3C. [Fig. 4] is a bottom view in which a part of the lower cover is broken.

As shown in FIG. 3, the crime prevention switch 1 includes a body 10 which is a molded product made of synthetic resin, conductive terminal screws 11 and 11, conductive terminal plates 12 and 12, and the presence or absence of a magnetic field. It is provided with a reed switch 13 which is turned on and off by a switch and a lower cover 14 which is a synthetic resin plate.

The main body 10 has a bilaterally symmetrical shape, and the terminal plates 12 and 12 are attached to the lower portion of the thick portion 10 a at the center of the main body 10 via rivets 15 and 15, respectively. Terminal screws 11 are respectively screwed onto the terminal plates 12 and 12. The reed switch 13 includes two lead wires 13a and 13a. One lead wire 13a has a tip soldered to one terminal plate 12, and the other lead wire 13a has a tip soldered to the other terminal board 12. The reed switch 13 is arranged in a space surrounded by the main body 10 and the lower cover 14. The main body 10 and the lower cover 14 are connected by eyelet metal fittings 16 and 16, the center of each of the eyelet metal fittings 16 and 16 is hollow, and the hollow portions 16a and 16a connect the security switch 1 to the wood screw ( It is used to attach to construction materials, etc. via (not shown).

By the way, the security switch 1 is used as follows. That is, for example, the security switch 1 is attached to the door frame of the entrance door. In addition, a permanent magnet is attached to the front door. This magnet is attached so that it will be in a position facing the security switch 1 when the front door is closed. Therefore, when the front door is open, the magnetic field generated by the magnet body does not reach the security switch 1, the reed switch 13 is in the off state, and there is no electrical conduction between the terminal screws 11 and 11. However, when the front door is closed, the magnetic field generated by the magnet body reaches the crime prevention switch 1, the reed switch 13 is turned on, and the terminal screws 11 and 11 are electrically connected. That is, by connecting the electric lines to the terminal screws 11 and 11, respectively, the open / closed state of the entrance door can be detected by the security switch 1.

[Problems to be solved by the device]

 However, in the above-described reed switch attachment structure, that is, the attachment structure by soldering, the heat generated during soldering adversely affects the reed switch, which deteriorates the magnetic field sensitivity characteristics of the reed switch. There was a problem that it would end up.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an attachment structure for a reed switch that does not cause characteristic deterioration.

[0008]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention has a structure for attaching a lead switch to a reed switch built-in device, and a pair of lead wire holding portions for holding lead wires for electrical connection. A mounting terminal plate is provided, and each lead wire from the reed switch is inserted into the lead wire holding portion of the pair of mounting terminal plates to incorporate the lead switch.

[0009]

[Action]

 With the above configuration, by inserting each lead wire from the reed switch into the lead wire holding part of each mounting terminal board, the lead switch can be incorporated into the reed switch embedded device without soldering. You can do it.

【Example】

 Hereinafter, an embodiment of a reed switch attachment structure according to the present invention will be described in detail with reference to FIG. 1, and a crime prevention as an embodiment of a device using the reed switch attachment structure according to the present invention will be described. The switch will be described in detail with reference to FIG. 1A and 1B are diagrams showing a state in which a reed switch is attached to a pair of mounting terminal plates. FIG. 1A is a plan view, FIG. 1B is a front view, and FIG. 1C is a side view. is there. 2A and 2B are views showing the security switch, FIG. 2A is a plan view, FIG. 2B is a partially cutaway front view, and FIG. 2C is a partially cutaway bottom view. Is.

As shown in FIG. 1, the reed switch mounting structure of the present invention is characterized by a pair of mounting terminal plates 20 and 20. That is, each of the mounting terminal plates 20 and 20 is formed by processing a material having both conductivity and spring property, such as a phosphor bronze plate. The mounting terminal plate 20 includes a base portion 21 and a lead wire holding portion 22. . The base portion 21 is provided with a rivet hole 21a for attaching the mounting terminal plate 20 to a device incorporating a reed switch. Further, at the end of the base portion 21, there is formed a lead wire holding portion 22 in which the holding pieces 22a, 22a are bent and erected so as to face each other. Further, the tip end of the lead wire holding portion 22 is bent so as to open in a substantially C-shape in a side view so that the lead wire 13a of the reed switch 13 can be easily inserted. The distance between the holding pieces 22a, 22a is such that the holding pieces 22a, 22a are substantially in contact with each other due to the spring property when the lead wire 13a of the reed switch 13 is not inserted.

The pair of mounting terminal plates 20 and 20 as described above are attached to the reed switch built-in device through the respective rivet holes 21a. Then, the lead wires 13a, 13a from the reed switch 13 are inserted into the lead wire holding portions 22 of the pair of mounting terminal plates 20, 20, respectively. Then, the reed switch 13 can be attached to the reed switch built-in device through the pair of mounting terminal plates 20 and 20 without soldering.

Next, a crime prevention switch as an embodiment of a device using the reed switch attachment structure of the present invention will be described with reference to FIG. Note that the security switch shown in FIG. 2 has substantially the same configuration as the security switch described in the related art, and the same parts are designated by the same reference numerals, so that detailed description of the same parts will be omitted. The description is omitted.

The security switch 1 shown in FIG. 2 is different from the conventional one in that it is characterized by the following configuration. That is, when attaching the terminal plate 12 below the thick portion 10a of the body 10 of the crime prevention switch 1 via the rivet 15, the terminal plate 12 and the mounting terminal plate 20 shown in FIG. Attach at the same time. After that, the lead wires 13a, 13a from the reed switch 13 are inserted into the lead wire holding portions 22 of the respective mounting terminal plates 20. Then, the reed switch 13 is assembled and attached to the security switch 1 without soldering, and the security switch 1 is turned on / off depending on the presence or absence of a magnetic field. Therefore, in the security switch 1 as described above, since the reed switch 13 can be assembled and attached without soldering, the workability of assembling is good, and the magnetic field sensitive characteristics of the reed switch 13 due to the heat of soldering Does not deteriorate.

[0015]

[Effect of device]

 Since the reed switch attachment structure of the present invention is constructed as described above, it is easy to insert the lead wires from the reed switch into the lead wire holding portions of the pair of mounting terminal plates. Since the reed switch can be built in and attached to the reed switch, it is possible to provide an excellent reed switch attachment structure that does not require soldering and does not deteriorate the characteristics of the reed switch due to the heat of soldering.
