Abstract
The utility model discloses an electric energy metering box shell, comprising a base (1) and a cover shell (2), wherein the side wall of the cover shell (2) is provided with a plurality of radiating slot holes (3); one end of the side wall of the cover shell (2), close to the base (1), is outwards and convexly provided with a positioning step (4) for being clamped with the base (1); and one ends of the radiating slot holes (3), close to the base (1), extend to the end surface of the cover shell (2) close to the base (1) along the direction of a bottom plate (1.1) of the base (1). The electric energy metering box shell can improve the qualification rate of finished products.
Description
Technical field
The utility model relates to a kind of protection housing of electric power meter, specifically is a kind of electric energy metrical tank shell.
Background technology
The electric energy metrical tank shell of prior art as shown in Figure 1 and Figure 2, it comprises base and lid shell 102, be equipped with on the two side of described lid shell 102 and be long (leading to) hole 103 of several heat radiations that lattice-shaped distributes, one end evagination of the close base of the sidewall of described lid shell 102 is useful on the positioning step 101 with the base clamping, and there is distance near an end 1031 of bases and the sidewall of lid shell 102 in each heat radiation slotted hole 103 near between the end face 1021 of base.
There is following defective in the electric energy metrical tank shell of above prior art: during die casting lid shell, must use the mould of band core-pulling mechanism, the step of loosing core is with pore-forming, and heat radiation slotted hole peripheral part ftractures easily when loosing core, so the product rejection rate height, promptly yield rate is low.
The utility model content
The technical problems to be solved in the utility model is that a kind of electric energy metrical tank shell that can improve product qualified rate is provided.
Technical solution of the present utility model is, a kind of electric energy metrical tank shell with following structure is provided, it comprises base and lid shell, the sidewall of described lid shell is provided with several heat radiation slotted holes, one end evagination of the close base of the sidewall of described lid shell is useful on the positioning step with the base clamping, and described heat radiation slotted hole extends to the end face that covers the close base of shell side wall near an end of base to the base plate direction of base.
After adopting above structure, the utility model electric energy metrical tank shell compared with prior art has the following advantages:
Because described heat radiation slotted hole extends to the end face that covers the close base of shell side wall near an end of base to the base plate direction of base, being described heat radiation slotted hole extends always and is provided with opening at the lid shell side wall near on the end face of base to the base plate direction of base, like this, when die casting should be covered shell, only need on the bed die of lid shell, be provided with and the corresponding raised line of heat radiation long hole shape that covers shell, behind the die cast, jack-up the making it that only foundry goods need be made progress breaks away from bed die and gets final product, the Therefore, omited manufacture process of loosing core, simplified production technology, the defective that having avoided looses core causes foundry goods to ftracture has improved product qualified rate; And mould also needn't be provided with core-pulling mechanism, so reduced production cost, has simplified production technology.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As Fig. 3, Fig. 4, shown in Figure 5, the utility model electric energy metrical tank shell, it comprises base 1 and lid shell 2.The sidewall of described lid shell 2 is provided with and is several heat radiation slotted holes 3 that lattice-shaped distributes, and an end evagination of the close base 1 of the sidewall of described lid shell 2 is useful on the positioning step 4 with base 1 clamping.Described heat radiation slotted hole 3 extends to base plate 1.1 directions of base 1 near an end 3.1 of bases 1 and cover the end face 2.1 of shell 2 sidewalls near base 1, and promptly described heat radiation slotted hole 3 extends always and be provided with opening on the close end face 2.1 of base 1 of lid shell 2 sidewalls to base plate 1.1 directions of base 1.
Claims (1)
1. electric energy metrical tank shell, it comprises base (1) and lid shell (2), the sidewall of described lid shell (2) is provided with several heat radiation slotted holes (3), one end evagination of the close base (1) of the sidewall of described lid shell (2) is useful on the positioning step (4) with base (1) clamping, it is characterized in that: described heat radiation slotted hole (3) extends to the end face (2.1) that covers the close base (1) of shell (2) sidewall near base plate (1.1) direction of an end (3.1) to base (1) of base (1).
