Background technology
Switch cubicle is a kind of electric equipment, is provided with a lot of equipment in switch cubicle, because load is very large, very important to the detection of temperature rise in switch cubicle.When temperature rise is detected, can use temperature rise testing circuit, when circuit board is fixed, adopt fixed case.Existing circuit board fixed case, its surrounding is the body structure of sealing, when placing circuit board, directly circuit board is put in case, then circuit board is fixed, last fixed roof.Its circuit board fixing very inconvenient, and when circuit board being detected to welding, during especially by multilayer circuit board, need detect welding from taking-up in casing again by circuit board, and it is very inconvenient to operate.And the circuit that has circuit to connect on circuit board, when circuit board is fixed, easily damages circuit, thereby cause the damage of whole circuit board.
Summary of the invention
The invention provides temperature rise circuit board fixed case in a kind of switch cubicle, it can be protected circuit board, and simple in structure, is convenient to installation and the maintenance welding of circuit board.
For solving above-mentioned technical problem, the present invention by the following technical solutions:
Temperature rise circuit board fixed case in switch cubicle; it comprises rectangle base plate and is fixed on the side plate fixed leg on four angles of base plate; on described side plate fixed leg, be provided with two with perpendicular two the side plate holddown grooves of base plate; between the side plate holddown groove of adjacent two side plate fixed legs, card has side plate; on described side plate fixed leg, be also provided with circuit board fixing groove; described circuit board fixing groove is positioned at a side adjacent compared with minor face perpendicular bisector with base plate, is provided with a layer circuit board protective layer in described circuit board fixing groove.
Further technical scheme is:
The top of described side plate fixed leg is provided with top board fixing hole.
On described side plate fixed leg, be provided with two circuit board fixing grooves.
Distance between two circuit board fixing grooves is greater than 3 centimetres and be less than 10 centimetres.
Described circuit board fixing groove is positioned on two horizontal planes.
The degree of depth of described side plate holddown groove is greater than 0.5 centimetre and be less than 1 centimetre.
Described circuit board protective layer is rubber.
Compared with prior art, the invention has the beneficial effects as follows:
1, in use, only circuit board need be inserted and circuit board can be fixed in circuit board fixing groove, the fixed form of its circuit board is simple, and when circuit board is overhauled, only side plate need be detached in side plate holddown groove, not need circuit board to take out, be convenient to the maintenance of circuit board.
2, in circuit board fixing groove of the present invention, be provided with a layer circuit board protective layer, make circuit board when installing fixedly, avoid too hard material to damage the route of circuit board, circuit board is protected.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of the present invention while not inserting side plate.
Label in figure is: 1, base plate; 2, side plate fixed leg; 21, side plate holddown groove; 22, top board fixing hole; 23, circuit board fixing groove; 3, side plate.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.Embodiments of the present invention include but not limited to the following example.
[embodiment]
Temperature rise circuit board fixed case in switch cubicle as depicted in figs. 1 and 2, it comprises rectangle base plate 1 and is fixed on the side plate fixed leg 2 on four angles of base plate 1, on described side plate fixed leg 2, be provided with two with perpendicular two the side plate holddown grooves 21 of base plate 1, between the side plate holddown groove 21 of adjacent two side plate fixed legs 2, card has side plate 3), on described side plate fixed leg 2, be also provided with circuit board fixing groove 23, described circuit board fixing groove 23 is positioned at a side adjacent compared with minor face perpendicular bisector with base plate 1, in described circuit board fixing groove 23, be provided with a layer circuit board protective layer.
In the present invention, on the basis of existing technology, the casing of sealing is improved, the sidewall that makes casing is dismountable structure.Side plate is connected by side plate fixed leg 2, make the sidewall of sealing detachable, when circuit board is overhauled, only side plate need be pulled down, can overhaul circuit board, very convenient.Avoid circuit board to take out in casing.When circuit board is fixed, only need be by circuit board along inserting in circuit board fixing groove 23 compared with the direction of minor face perpendicular to base plate, 4 angles of circuit board are laid respectively in the circuit board fixing groove 23 of 4 side plate fixed legs 2 can be fixed circuit board.Simple and the Stability Analysis of Structures of the fixed form of circuit board, should not rock.Because side plate fixed leg 2 is metal materials; it very easily damages the circuit on circuit board; so at the interior layer circuit board protective layer that arranges of circuit board fixing groove 23; can protect the circuit on circuit board; avoid circuit board when mobile, the circuit on 2 pairs of circuit boards of side plate fixed leg damages.
The top of described side plate fixed leg 2 is provided with top board fixing hole 22.Top board fixing hole is for connecting lateral plate fixed leg and top board, its can be set to screwed hole or porose in have the irregular hole of water caltrop.
In order further can to fix two circuit boards simultaneously, on described side plate fixed leg 2, be provided with two circuit board fixing grooves 23.When circuit structure is more complicated, circuit board will have two, and two circuit board fixing grooves 23 are set on side plate fixed leg 2, can fix two circuit boards.
On circuit board, be integrated with a lot of electronic devices and components, in order to fix two circuit boards, the distance between two circuit board fixing grooves 23 is greater than 3 centimetres and be less than 10 centimetres.
For the ease of fixing of circuit board, described circuit board fixing groove 23 is positioned on two horizontal planes.Two circuit board fixing grooves are positioned on two different horizontal planes, are convenient to the movement of circuit board.
The degree of depth of described side plate holddown groove 21 is greater than 0.5 centimetre and be less than 1 centimetre.Side plate holddown groove 21 is for fixed side, and the degree of depth of side plate holddown groove 21 concerns the degree of depth that side plate embeds side plate fixed leg, and its degree of depth is darker, and it is more stable that side plate is fixed, so the degree of depth of side plate holddown groove 21 is greater than 0.5 centimetre.But the degree of depth is too dark, just higher to the requirement of side plate fixed leg, from side plate fixed leg with to side plate fixing-stable degree, to consider on both side, the degree of depth of side plate holddown groove 21 is less than 1 centimetre.
Described circuit board protective layer is rubber.Rubber has certain flexibility, can protect circuit board, can not scratch the circuit layer of circuit board.
Be as mentioned above embodiments of the invention.The present invention is not limited to above-mentioned execution mode, and anyone should learn the structural change of making under enlightenment of the present invention, and every have identical or close technical scheme with the present invention, within all falling into protection scope of the present invention.
