Abstract

The utility model relates to a sensor switch which is used for various occasions which switch on a circuit when a handle is pulled, such as a portfolio for anti-theft; no matter the portfolio is put in whatever way, an alarm circuit is switched on to give an alarm when the portfolio is lifted. The principle is that both ends of the handle are provided with a mutual conductive pin which is movably connected with metal connecting fittings (which are used as two joints of a switch) which is fixed on a portfolio body. When the handle is pulled, the two metal connecting fittings are broken by the handle to switch on the alarm circuit.

Description

Handle type switch for anti-theft of trunk and bag

The invention belongs to sensor class switch, close in the time of can being widely used in various band handle object carrying handle and open circuit.

Open and close circuit working when having many occasions that object need be extracted.For example, the anti-alarms of stealing of case and bag that Chinese patent application numbers 88220729,6 is introduced, burglar alarm effectively when the chest horizontal positioned, but then powerless to some occasion (on train luggage rack) that only allows case and bag to place vertically.At this moment, just can report to the police by start-up circuit, then can mend this deficiency if lift case and bag.

The purpose of this invention is to provide a kind of novel switch, start related circuit when making carrying handle reliably.

The present invention finishes as follows.Handle is fixed on by two metal connecting pieces to be desired to carry on the object, the bipod of two connector while double as switches, and handle itself constitutes a good conductor together with latch.Handle is connected with connector by latch, and when latch partly contacted with the metal of connector, two connectors were by the handle short circuit, and switch connection is when latch contacts then two connector not conductings mutually, switch disconnection with connector insulation part.

Below in conjunction with accompanying drawing invention is described in further detail:

Fig. 1 is concrete structure figure of the present invention.Referring to Fig. 1.Connector (1) with excellent conductive performance and mechanical strength is connected with handle (2) by metal bolt (5).Handle two plug housing (3) is similarly metallic conductor, and by conductor (4) short circuit on the handle (2).Fig. 2 is the connector structure chart, is drilled with hole (6) on it, and hole (6) lower inside is lined with insulant (7).Not during carrying handle, latch (5) is the bottom of (6) in the hole, contacts with insulant (7), and switch is obstructed; During carrying handle, latch (5) touches mutually with top, connector hole (6), touches mutually with two groups of plug housings (3) of short circuit each other again simultaneously, thereby makes two connector short circuits, switch conduction.

Fig. 3 is used for the electrical schematic diagram of briefcase burglar alarm for the present invention.Bat-handle switch K1 and toggle switch K2 are serially connected with in the alarm circuit, and K2 is contained in the briefcase of band coded lock, has only the user just can open chest K switch 2.When K2 connected, no matter how case and bag were placed, and anyone mentions briefcase just will trigger alarm equipment alarm, and the user then can open chest and turn off K2 when controlling oneself suitcase, removed warning function.

The embodiment of the invention is to be used for the briefcase burglar alarm, and its electrical schematic diagram as shown in Figure 3.Connector (1) is made of brass, and the lower end thread cutting is to be fixed on the casing, and it is switch two contacts partly that screw thread stretches in the conductor, joins with warning circuit.The conductor (4) of gang socket (3) but compression moulding be encapsulated in the handle or be embedded on the handle surfaces, this example conductor 4 is used copper conductor, is encapsulated in the handle together with plug housing (3).Alarm adopts KD9561 integrated alarm circuit, and its power connection and K1K2 switch polyphone back join with battery, and all the other are by the subsidiary wiring diagram wiring of this integrated circuit.Toggle switch K2 packs the interior close handle of case into partly, and the user opens chest a little just can K switch 2.

Claims

1, a kind of sensor class switch is characterized in that switch is made up of connector (1), latch (5) and handle (2).

2, by the described switch of claim 1, it is characterized in that connector (1) made by the conduction good metal, porose it on (6) can therefrom be passed also metal bolt (5) and are freely moved up and down, and hole (6) lower inner wall is lined with insulant (7).

3, by the described switch of claim 1, it is characterized in that there is the metal bolt seat (3) of two groups of Fixed latches (5) usefulness at handle (2) two, two groups of plug housings (3) link to each other by the conductor (4) on the handle (2).
