Detailed description of the invention
Referring to Fig. 1 and Fig. 2, electronic installation 10 includes upper cover 11 and the lower cover 12 separably attached with upper cover 11, circuit board 20, fixture 30 and protective cover 40.Circuit board 20 is located between upper cover 11 and lower cover 12, and fixture 30 is used for connecting upper cover 11 and lower cover 12, and protective cover 40 is located at the surface of upper cover 11 for hiding fixture 30.
Please also refer to Fig. 3 to Fig. 5, upper cover 11 is provided with depression 13 and the installing hole 14 through with depression 13, and one end of fixture 30 is through installing hole 14 to connect upper cover 11 and lower cover 12, and the other end of fixture 30 is placed in depression 13.
Protective cover 40 is located at depression 13 and is sentenced covering fixture 30, the inner disc 42 of it outer 41 including circular ring and round pie structure.Inner disc 42 and outer 41 are made for metal material, and the thermal coefficient of expansion of metal material that the thermal coefficient of expansion of metal material that uses of outer 41 uses less than inner disc 42.Inner disc 42 is nested in outer 41 and interference fit, and protective cover 40 is fixed on depression 13 places by outer 41, and makes the surface of protective cover 40 in the same plane with the surface of upper cover 11.Thus, protective cover 40 can not be disassembled by user easily, and protective cover 40 is just firmly fixed on upper cover 11 to hide fixture 30.
Circuit board 20 is provided with the corresponding perforation 21 of installing hole 14, signal conduction point 22 and signal cut-off point 23.Signal conduction point 22 identical with the structure of signal cut-off point 23 and be spaced on circuit board 20 on two the concentrically ringed circumference being formed for the center of circle of center boring a hole 21, each concentrically ringed circumference is designed with signal conduction point 22 and signal cut-off point 23.Wherein, on each concentrically ringed circumference, the quantity of signal conduction point 22 is 1, the quantity of signal cut-off point 23 respectively 23 and 11 on each concentrically ringed circumference.Signal conduction point 22 is electrically connected with other electronic devices and components on circuit board 20 by circuit board 20.
Fixture 30 penetrating mounting holes 14 and perforation 21 connect upper cover 11 and lower cover 12 with thread connecting mode.Fixture 30 is arranged with the second conduction element 32 and clasp 33 that the first conduction element 31 electrically connects with the first conduction element 31.First conduction element 31 and the second conduction element 32 are the conducting strip with elastic strip.First conduction element 31 and the second conduction element 32 being designed with the contact point 310 of projection, being electrically connected with the signal conduction point 22 on two concentric circulars on circuit board 20 respectively by contact point 310 so that electrically connecting between signal conduction point 22.When the first conduction element 31 and the second conduction element 32 are connected with signal conduction point 22, now the first conduction element 31 and the second conduction element 32 are arranged in first mode with signal conduction point 22, now electrically connect between signal conduction point 22, and electronic installation 10 could normal operation.Clasp 33 is used for fixing the first conduction element 31 and the second conduction element 32 in fixture 30.
When user dismantles electronic installation 10 privately, namely need rotary mount 30 so that upper cover 11 and lower cover 12 separate.And protective cover 40 covers in fixture 30 and fixture 30 is formed protection, user just cannot easy removal electronic installation 10.Even with person, protective cover 40 is disassembled, and when rotary mount 30, fixture 30 drives the first conduction element 31 and the second conduction element 32 to move with separating signal firing point 22, and now the first conduction element 31 and the second conduction element 32 are arranged in the second pattern with firing point 22.When user does not know that the first conduction element 31 and the second conduction element 32 need to electrically connect with signal conduction point 22, add signal conduction point 22 identical with signal cut-off point 23 structure, and cannot distinguish with outward appearance, thus substantially increase the difficulty re-assemblied.Such as user is when re-assemblying, just probably make to be connected between contact point 310 with signal cut-off point 23, without making to be connected between the first conduction element 31 and the second conduction element 32 and firing point 22, so that the first conduction element 31 and the second conduction element 32 are arranged rather than first mode setting in the second pattern with firing point 22, to cause the mistake assembling of electronic installation.
In order to increase the difficulty re-assemblying electronic installation 10, need the quantity making signal cut-off point 23 quantity more than signal conduction point 22, as in the present embodiment, the quantity of signal cut-off point 23 respectively 23 and 11 on two concentrically ringed circumference, the quantity of signal conduction point 22 is all 1.It is appreciated that the quantity of signal conduction point 22 and signal cut-off point 23 is not limited to the particular number enumerated in present embodiment.
Electronic installation 10 provided by the invention, fixture 30 is hidden by arranging protective cover 40 on electronic installation 10, and the first conduction element 31 and the second conduction element 32 being connected with the signal conduction point 22 on circuit board 20 is set on fixture 30, add the difficulty of dismounting and device electronic installation 10 again, it is achieved thereby that prevent the purpose that electronic installation 10 is arbitrarily dismantled by user and assembled.
Those skilled in the art also can do other change in spirit of the present invention, and these changes done according to present invention spirit, all should be included in invention which is intended to be protected certainly.
