Description
Technical field
The utility model relates to a kind of electronic instruction experimental provision, and a kind of experimental box circuit board module box of more specifically saying so is particularly useful for the student experimenting operation.
Background technology
At present, the electronic instruction experimental box of modular is widely used in the teaching of each colleges and universities, technical school.Chinese patent publication number: CN2596482, Granted publication day is the electronic experiment case that the utility model patent " flush bonding module experimental box " on Dec 31st, 2003 has just been announced a kind of modular, the electronic experiment case of this modular has dirigibility more for all-in-one-piece experimental box of past, the student can change the function that any one module is wherein adjusted experimental box at any time.But the circuit board module of this utility model is directly exposed to outer, because student's operative technique of the operation that experimentizes usually and unskilled.Therefore metal objects such as electric wire or tweezers very easily touches electronic component on the circuit board in experimentation, and causes the damage of circuit board, causes waste.Existing in the market a kind of circuit board protected mode is to add the poly (methyl methacrylate) plate that lid layer separates on circuit board, is connected with circuit board by double-screw bolt.But the lower face of circuit board is not protected, and pulls down when circuit board and very easily causes damage when depositing.Simultaneously, in this manner, when changing circuit board, need pull down poly (methyl methacrylate) plate earlier after, circuit board could be pulled down from the experimental box base plate, also need special instrument, very inconvenient.And during student experimenting, circuit board module is to need often to change, and it is more not convenient that this mode just seems, wastes time and energy.
Summary of the invention
The purpose of this utility model is to overcome in the prior art inadequately to the circuit board protection, and circuit board defective and deficiency such as dismounting inconvenience when changing provides a kind of experimental box circuit board module box of two-layer protective cover up and down that has.
To achieve these goals, the technical solution of the utility model is: a kind of experimental box circuit board module box, comprise the upper strata protective cover that is installed on the quadrilateral circuit board, and corresponding upper strata, the below of described circuit board protective cover is equipped with lower floor's protective cover.
Be equipped with two grabs on two broadsides of described lower floor protective cover or upper strata protective cover, corresponding grab is equipped with buckle slot on two broadsides of upper strata protective cover or lower floor's protective cover.
Copper post hole on four angles of described upper strata protective cover and lower floor's protective cover on the corresponding circuits plate is provided with the copper column jecket; copper post on the experimental box motherboard passes copper column jecket, the copper post hole on the circuit board and the copper column jecket on the protective cover of upper strata on lower floor's protective cover, and the external thread in the copper column jecket on the protective cover of described upper strata on the corresponding copper post is provided with the insulation nut.
Be equipped with two boss on two long limits of described lower floor protective cover, have on lower floor's protective cover and the corresponding pin holes of circuit board upper spring contact pin.
Described upper strata protective cover adopts the transparent organic glass material to make.
Pass through technique scheme; the beneficial effects of the utility model are: 1. two-layer protective cover was protected circuit board fully about the utility model adopted; the student can not cause the damage of circuit board because of because of carelessness metal parts being touched the electronic component on the circuit board in experiment or when changing circuit board module; avoid waste, saved cost.2. the utility model be when the student need change master die, and protective cover and circuit board can be used as that an integral body is dismantled and prior art is relatively dismantled more conveniently, also do not need to use special instrument, not only save time but also laborsaving.3. the utility model is protected circuit board completely, has solved the problem that causes circuit board damage in circuit board transportation, the keeping process because of collision, dust etc.4. upper strata of the present utility model protective cover adopts transparent material to make, and helps the student clearly to observe electronic component on the circuit board.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model structural representation of protective cover 2 at the middle and upper levels;
Fig. 3 is the structural representation of lower floor's protective cover 3 in the utility model.
Among the figure, circuit board 1, upper strata protective cover 2, lower floor's protective cover 3, grab 4, buckle slot 5, copper post hole 6, copper column jecket 7, insulation nut 8, boss 9, pin holes 10.
Embodiment
The utility model is described in further detail below in conjunction with description of drawings and embodiment:
Referring to Fig. 1, a kind of experimental box circuit board module box comprises the upper strata protective cover 2 that is installed on the quadrilateral circuit board 1, and the below of circuit board 1 and upper strata protective cover 2 corresponding positions are equipped with lower floor's protective cover 3.On the upper strata protective cover 2 on the corresponding circuits plate 1 test point and scalable device have instrument connection, thereby and adopt the transparent organic glass material to make to be convenient to learn that dirt is observed, test.
Referring to Fig. 2, Fig. 3, be equipped with two grabs 4 on two of lower floor's protective cover 3 are wide, two wide grabs of on the corresponding lower floor protective covers 4 of upper strata protective cover 2 are equipped with buckle slot 5.
Have on lower floor's protective cover 3 and the corresponding pin holes 10 of circuit board 1 upper spring contact pin, be used for the spring contact pin and contact with the experimental box motherboard.
Be equipped with two boss 9 on two long limits of lower floor's protective cover 3, circuit board 1 is placed on the copper column jecket 7 on boss 9 and the lower floor's protective cover 3.Buckle when upper strata protective cover 2 and lower floor's protective cover 3 and to be combined into one when whole, corresponding 4 pairs of copper column jeckets 7 and boss 9 avoid it to rock circuit board 1 stable being fixed in the protective cover on the levels protective cover.
Referring to Fig. 1, the copper post hole 6 on four angles of upper strata protective cover 2 and lower floor's protective cover 3 on the corresponding circuits plate 1 is provided with copper column jecket 7.When install changing circuit board 1 module, the copper post on the experimental box motherboard is passed copper column jecket 7 on copper column jecket 7 on lower floor's protective cover 3, copper post hole 6 on the circuit board 1 and the upper strata protective cover 2.There is the external thread on insulation nut 8 and the experimental box motherboard copper post to screw in the copper column jecket 7 on the upper strata protective cover 2, circuit board 1 module is fixed on the experimental box motherboard.During being provided with of insulation nut 8 can be avoided testing because of the phenomenon generation of circuit board line that maloperation caused with the short circuit of copper post.
In usual use, when needing to change circuit board 1 module, only need pull down insulation nut 8, circuit board 1, upper strata protective cover 2 and lower floor's protective cover 3 are done as a whole pulling down get final product.
