Embodiment
Below in conjunction with accompanying drawing, structural principle of the present utility model and principle of work are described in detail:
Please refer to Fig. 1, it illustrates the exploded view of the electronic installation according to the utility model one embodiment.Electronic installation 100 is such as a tamper (tamper-resistant) electronic installation, such as can be installed in the sensor (DoorWindow Sensor) on window or door, in order to detect the state of window or door, and return state by wireless communication mode.
Electronic installation 100 comprises shell 110, battery 120, circuit board 130, sheet metal 140 and insulation strip 150.Shell 110 comprises Part I 111 and Part II 112.Part I 111 and Part II 112 are optionally be separated or cover.Battery 120 and circuit board 130 can be located between Part I 111 and Part II 112, can protect battery 120 and circuit board 130 after Part I 111 and Part II 112 cover.
Circuit board 130 is fixed in Part I 111.Circuit board 130 comprises the first contact 131, second contact 132, the 3rd contact 133, the 4th contact 134, the 8th contact 135, decision circuitry 136, first line 137 and the second circuit 138.Contact 131 and contact 132 are such as metal clips, and it can be welded in circuit board 130.Contact 132 is electrically connected on contact 135 by first line 137.
After in the Part I 111 that battery 120 is installed on shell 110, the first pole 121 of battery 120 contacts and is electrically connected on contact 131, and the second pole 122 of battery 120 contacts and is electrically connected on contact 132; Thus, battery 120 can provide power supply to circuit board 130.Contact 131 is electrically connected on first feeder ear (such as VCC) of circuit board 130, and contact 133 is electrically connected on second feeder ear (such as earth terminal) of circuit board 130.When contact 135 is not electrically connected on contact 133 by sheet metal 140, the second pole 122 of battery 120 is not electrically connected on the second feeder ear of circuit board 130, and now circuit board 130 cannot draw electric energy from battery 120, therefore can not operate; When contact 135 is electrically connected on contact 133 by sheet metal 140, the second pole 122 of battery 120 can be electrically connected on the second feeder ear of circuit board 130, and now circuit board 130 can draw electric energy and normal operation from battery 120.
Please refer to the local constitutional diagram that Fig. 2 A and Fig. 2 B, Fig. 2 A illustrates the electronic installation of Fig. 1, and Fig. 2 B illustrates the cut-open view of electronic installation along direction 2B-2B ' of Fig. 2 A.Sheet metal 140 comprises the 5th contact 141, the 6th contact 142 and the 7th contact 143.Contact 141 is electrically connected on the contact 135 of circuit board 130, to be electrically connected on contact 132 by contact 135.In one embodiment, the contact 141 of sheet metal 140 can adopt seam technology to be fixed on the contact 135 of circuit board 130, makes sheet metal 140 be not easy to depart from circuit board 130.As shown in Figure 2 B, contact 142 is pressed on the contact 133 of circuit board 130 by insulation strip 150; In addition, compress sheet metal 140 times at Part II 112, force the contact 143 of sheet metal 140 to be also pressed on the contact 134 of circuit board 130, and then make the contact 143 of sheet metal 140 be electrically connected on decision circuitry 136 by the contact 134 of circuit board 130.
Sheet metal 140 more comprises lamellar body 144, first shell fragment 145, second shell fragment 146 and the 3rd shell fragment 147.First shell fragment 145 connects lamellar body 144 and connects lamellar body 144 and contact 142 with contact 141, second shell fragment 146, and the 3rd shell fragment 147 connects lamellar body 144 and contact 143.In addition, sheet metal 140 can be the integrally formed sheet metal component adopting sheet metal engineering method to be formed.
Contact 143 relatively contact 141 can be elastically deformed.Thus, as shown in Figure 2 B, after Part I 111 and Part II 112 cover, the pressure section 1121 of Part II 112 is pressed on lamellar body 144, forces lamellar body 144, first shell fragment 145 and the 3rd shell fragment 147 deformation and storage elasticity potential energy; And after Part II 112 is separated with Part I 111 (as shown in Figure 4), lamellar body 144, first shell fragment 145 and the 3rd shell fragment 147 can discharge elasticity potential energy and reset, and the contact 143 of sheet metal 140 is separated (released state as shown in Figure 4) with the contact 134 of circuit board 130.
When user buys electronic installation 100, electronic installation 100 comprises insulation strip 150, and insulation strip 150 can prevent electronic installation 100 from drawing the electric energy of battery 120, avoids unnecessary power consumption, so time electronic installation 100 can not operate.When user brings into use electronic installation 100, insulation strip 150 can be taken out in electronic installation 100, make electronic installation 100 can draw the electric energy of battery 120 and come into operation, and tamper (tamper-resistant) function is provided.In other words, the electronic installation 100 before using comprises insulation strip 150, and the electronic installation 100 in using does not comprise insulation strip 150.
As shown in Figure 2 A, insulation strip 150 comprises first end 151 and the second end 152.As shown in Figure 2 B, first end 151 is sandwiched between the contact 133 of circuit board 130 and the contact 142 of sheet metal 140, with the contact 133 of the contact 142 of (isolation) sheet metal 140 that insulate with circuit board 130.In the present embodiment, second end 152 of insulation strip 150 is positioned at electronic installation 100 outer (as shown in Figure 2 A), so be not easy to use second end 152 of person by exposing, insulation strip 150 is extracted out between sheet metal 140 and circuit board 130, makes electronic installation 100 can draw the electric energy of battery 120 and come into operation.In one embodiment, the material of insulation strip 150 is such as mylar (Mylar).In addition, as shown in Figure 2 A, Part I 111 has one near the perforation 111a of contact 133, and the second end 152 of insulation strip 150 can be exposed to outside shell 110 through perforation 111a.
The 6th contact that Fig. 3 illustrates the sheet metal of Fig. 2 B is electrically connected on the cut-open view of the 3rd contact of circuit board.In insulation strip 150 from after extracting out between sheet metal 140 and circuit board 130, the contact 133 of contact 142 contact circuit plate 130 under the ordering about of elastic-restoring force of sheet metal 140, make the contact 133 of the contact 142 electrical connection circuit plate 130 of sheet metal 140, the circuit board 130 of electronic installation 100 like this draws electric energy by the first contact 131 and the 3rd contact 133 from battery 120 (battery 120 is illustrated in Fig. 1) and comes into operation.
As shown in Figure 2 B, after Part I 111 and Part II 112 cover, the contact 143 of sheet metal 140 is electrically connected on circuit board 130, and decision circuitry 136 produces the first level signal that has low voltage level (Low) according to this.After coming into operation, if the Part II 112 of electronic installation 100 is separated with Part I 111 (such as by generally overhauling, illegal destruction, do not expect to come off or other any factor caused), as shown in Figure 4, the contact 143 of sheet metal 140 is discharged and is resetted, and contact 143 is separated with the contact 134 of circuit board 130.Now, decision circuitry 136 produces the second level signal that has high voltage level (High).
As from the foregoing, decision circuitry 136 can judge whether the contact 143 of sheet metal 140 is electrically connected on the decision circuitry 136 of circuit board 130.Say further, decision circuitry 136 can change from the voltage level between the first level signal with the second level signal and judges whether Part I 111 is separated with Part II 112.When decision circuitry 136 judges that Part I 111 to be separated (as being changed to High from Low) with Part II 112, electronic installation 100 also can send an anti-theft warning sound or a backstage line circular, thus effectively can play the object of the safe operation safeguarding electronic installation 100 and total system thereof.
