Above-mentioned terminal box can be used in inflammable and explosive occasion, but still be come with some shortcomings：It is sealed not at the top of terminal box
Foot need to open cover board there are the hidden danger in aqueous intrusion box and when dismounting box body and could dismantle, inconvenient.
Invention content
The utility model provides a kind of wiring of locomotive transformer oil pump for the above problem existing for existing technology
Box, technical problem to be solved in the utility model are：How the dismounting convenience of terminal box is improved.
The purpose of this utility model can be realized by following technical proposal：
A kind of oil pump terminal box, the box body including up/down perforation, the bottom surface of the box body offer several mounting holes
One, the top surface of the box body offers several mounting holes two, which is characterized in that the lateral wall of the box body offers to house
The inner groovy of bolt, the opening of the inner groovy is towards on the outside of box body, and the inner cavity of the inner groovy and box body mutually completely cuts off, the peace
Dress hole one and mounting hole two are connected with inner groovy.
The inner cavity of box body can house electric wire and connect and protect electric wire, and the outside of box body is used equipped with wiring hole in the prior art
In electric wire by connection, the bottom of box body sets several mounting holes one that can allow bolt by the way that box body to be fixed to the portion on periphery
It on part, is fixed so as to fulfill installation, the top setting mounting hole two of box body is used to install cover board.It is opened by the lateral wall in box body
If the inner groovy with box cavity isolation, and mounting hole one and mounting hole two is made to be connected with inner groovy, it is each passed through in this way
The bolt of mounting hole one and mounting hole two can be placed in inner groovy, more compact structure, can be directly from outer to one He of mounting hole
Bolt dismantling in mounting hole two, and cover board need not be opened when needing and dismantle box body, dismounting is more convenient；Indent channel opening is outwardly
Setting, even if water is penetrated into along bolt in this way, can also discharge from inner groovy, aqueous is avoided to accumulate invasion, is additionally convenient for
Operator dismounts bolt from outer, further improves the dismounting convenience of terminal box.
In a kind of above-mentioned oil pump terminal box, the bottom end opening edge of the box body circumferentially offers seal groove
One, in a ring, the mounting hole one is located at the periphery of the seal groove one to the seal groove one.By on the bottom end opening side of box body
Edge sets seal groove one and mounting hole one is made to be set on the periphery of seal groove one, and the aqueous in the box body external world is invaded in this way after the completion of assembling
Enter bolt-clearance to be also difficult to enter tray interior, improve the leakproofness of terminal box.
In a kind of above-mentioned oil pump terminal box, the top opening edge of the box body circumferentially offers the close of annular
Sealing groove two, the mounting hole two are located at the periphery of the seal groove two.Similarly, it is set by the way that mounting hole two is set to be located at the top of box body
Seal groove two periphery, such box body external world aqueous is not easy to, from the intrusion at the top of box body, further improve the close of terminal box
Feng Xing.
In a kind of above-mentioned oil pump terminal box, the sealing of annular is embedded in the seal groove one and seal groove two
Circle, the section of the sealing ring are rounded or oval.Long-term dismounting junction box cover plate can deform, conventional seals rubber cushion elasticity
Difference, second fills and twists and will not press tightly, by the rounded or oval sealing ring that section is set to be in seal groove, in this way
Decrement is big in the axial direction for sealing ring, and cover board deformation remains to ensure preferable in sealing contact, ensure that the sealing of upper and lower surface
Effect.
In a kind of above-mentioned oil pump terminal box, several described mounting holes one and mounting hole two are circumferentially equal along box body
Even arrangement.Setting mounting hole one and mounting hole two are evenly arranged, and such box body upper and lower surface each point uniform force avoids local change
Shape causes seal failure, so as to more preferably ensure sealing effect.
In a kind of above-mentioned oil pump terminal box, the box body is aluminum casting or stainless steel part.Aluminum casting or stainless steel
Part good corrosion resistance is not easy heated combustion, and explosion-proof performance is good, safer.
Compared with prior art, it is as follows the advantages of the utility model：
1st, this terminal box is in the lateral wall of box body by opening up the inner groovy completely cut off with box cavity, and make mounting hole one with
And mounting hole two is connected with inner groovy, person easy to operation dismounts bolt from outer indent channel opening outwardly, improves wiring
The dismounting convenience of box, in addition water penetrated into along bolt, can also be discharged from inner groovy, aqueous is avoided to accumulate invasion.
2nd, this terminal box is by the seal groove two in the top of box body setting annular, and mounting hole two is made to be located at seal groove two
Periphery, such box body external world aqueous is not easy to, from the intrusion at the top of box body, improve the leakproofness of terminal box.
