Abstract
The utility model discloses a terminal box of an electric energy meter, which has better sealing performance and comprises a terminal box body (3) and a terminal box cover (1), wherein the terminal box cover (1) is provided with screw holes (2); the terminal box cover (1) and the terminal box body (3) are matched and connected by screws; one part of a hole wall (2.1) of each screw hole (2) is higher than the outer surface of the terminal box cover (1); the part of the hole wall (2.1) of each screw hole (2) higher than the outer surface of the terminal box cover (1) is provided with at least one through hole (2.1.1); a sealing gasket (4) is arranged between the terminal box cover (1) and the terminal box body (3); and the terminal box cover (1), the sealing gasket (4) and the terminal box body (3) are sequentially connected.
Description
Technical field
The utility model relates to the electric energy meter technical field, specifically is a kind of electric energy meter terminal box.
Background technology
A kind of electric energy meter terminal box is arranged at present, and it comprises terminal box box body, terminal box lid (being end cap in the industry again), and terminal box lid and the terminal box box body merga pass screw that matches is connected.Also establish lead seal structure on the described terminal box lid, promptly lead seal hole is established on the next door of the screw hole on the terminal box lid, and the head of the screw that is adopted is provided with the through hole that passes for the lead sealing line.The main effect of terminal box lid is to protect the connection terminal that is installed in the terminal box box body, and lead seal structure is used to shut the terminal box lid with anti-electricity-theft.Though above-mentioned electric energy meter terminal box is simple in structure, easy to assembly, but, there is a through hole at the lead seal hole place on the one hand, be communicated with the terminal box lid inside and outside, be unfavorable for dustproof and waterproof, be poor sealing performance, on the other hand, terminal box lid and the terminal box box body version that the merga pass screw is connected that matches also causes its sealing property still relatively poor.
The utility model content
The technical problems to be solved in the utility model is that the better electric energy meter terminal of a kind of sealing property box is provided.
The technical solution of the utility model is, a kind of electric energy meter terminal box with following structure is provided, it comprises terminal box box body, terminal box lid, described terminal box lid is provided with screw hole, terminal box lid and the terminal box box body merga pass screw that matches is connected, some is higher than the outside surface of terminal box lid the hole wall of described screw hole, and the part that the hole wall of each screw hole is higher than the outside surface of terminal box lid is provided with at least one through hole; Be provided with sealing gasket between described terminal box lid and the terminal box box body, described terminal box lid, sealing gasket, terminal box box body connect in regular turn.
After adopting said structure, the utility model electric energy meter terminal box compared with prior art, have the following advantages: because the hole wall of described screw hole some be higher than the outside surface of terminal box lid, the part that the hole wall of each screw hole is higher than the outside surface of terminal box lid is provided with at least one through hole; Be provided with sealing gasket between described terminal box lid and the terminal box box body, described terminal box lid, sealing gasket, terminal box box body connect in regular turn, like this, saved original lead seal hole on the one hand, as long as the through hole that the lead sealing line passes on the head of through hole on the hole wall of each screw hole, screw can reach the purpose of shutting, between terminal box lid and terminal box box body, be provided with a sealant on the other hand, so the utility model electric energy meter terminal box has the better advantage of sealing property.
As improvement, each screw hole is provided with two through holes, and the center line of two through holes is same straight line, and the center line of this straight line and screw hole intersects, like this, can be more fixing lead sealing line, more help the raising of this practical new performance.
Description of drawings
Fig. 1 is the assembling synoptic diagram of the utility model electric energy meter terminal box.
Fig. 2 is the structural representation of the utility model electric energy meter terminal box.
Shown in the figure, 1, the terminal box lid, 2, screw hole, 2.1 hole walls, 2.1.1, through hole, 3, the terminal box box body, 4, sealing gasket.
Embodiment
Below in conjunction with accompanying drawing the utility model electric energy meter terminal box is described further.
The utility model electric energy meter terminal box, it comprises terminal box box body 3, terminal box lid 1, described terminal box lid 1 is provided with screw hole 2, terminal box lid 1 and the terminal box box body 3 merga pass screw that matches is connected, some is higher than the outside surface of terminal box lid 1 hole wall 2.1 of described screw hole 2, and the part that the hole wall 2.1 of each screw hole 2 is higher than the outside surface of terminal box lid 1 is provided with at least one through hole 2.1.1; Be provided with sealing gasket 4 between described terminal box lid 1 and the terminal box box body 3, described terminal box lid 1, sealing gasket 4, terminal box box body 3 connect in regular turn.Concrete structure is shown in Fig. 1 or 2.
In this example, each screw hole 2 is provided with two through hole 2.1.1, and the center line of two through hole 2.1.1 is same straight line, and the center line of this straight line and screw hole 2 intersects.Described sealing gasket 4 is arranged on the place that matches of described terminal box lid 1 and terminal box box body 3, and described sealing gasket 4 is a rectangular O-ring seal.
