Description

A kind of network filter housing with steam vent

Technical field

The utility model belongs to signal processing technology field and in particular to a kind of network filter housing with steam vent.

Background technology

Traditional closing class network filter housing, typically one independent band PIN needle base cavity and an independence Upper lid cavity, several line bags and certain glue solvent are installed in base cavity body, and pour into glue solvent in upper lid cavity, Then rear end section operation could be continued after encapsulating quiet for a long time putting, because glue is in the housing of closing, air circulation, lead to Setting time is long.This technological process leads to this work station time long, many in product, causes to wait waste.Take up room, cause Management wastes.Production cost is high, and the market competitiveness is low.

Utility model content

The purpose of this utility model is：For problem present in existing network filter housing, provide a kind of band The network filter housing of steam vent, housing cavity ventilation effect is good, and the glue solidifies, and the time shortens, and reduces wait, management, space Waste, reduce production cost, the market competitiveness is high.

To achieve these goals, the technical solution adopted in the utility model is：

A kind of network filter housing with steam vent, including upper lid and bottom seat, has cavity, chamber in the middle of described base Body surrounding is base wall, and the two ends of described base wall are provided with the exhaust groove to inner side depression, base and upper lid cooperation When, form steam vent between exhaust groove and upper lid, steam vent is connected with the cavity of base；Described exhaust groove includes groove Inwall and the recess sidewall being located at groove inner wall both sides, the apical side height of groove inner wall is less than the apical side height of base wall.

Preferably, described groove inner wall is obliquely installed, and forms outer aperture and be less than inner orifice between exhaust groove and upper lid Steam vent.

Preferably, described groove inner wall and the junction of recess sidewall arrange outer chamfering structure.

Preferably, the both sides of described base wall are provided with several PIN needle.

Preferably, described exhaust groove runs through whole base.

Due to employing technique scheme, the beneficial effects of the utility model are：

A kind of network filter housing with steam vent of the present utility model, by recessed in the setting exhaust of the two ends of base Groove, forms steam vent after upper lid and base engagement, thus by the inner chamber of housing and ft connection, solving traditional closing shell The slow problem of body glue curing.By being configured with the housing of steam vent so that producing during glue curing in housing cavity Heat, expanded by heating, discharged by steam vent, prevent black glue solution from being extruded at upper lid with base gap by air extrusion；With When again housing both sides formed steam vent, therefore can form convection current, exhaust effect is more preferably.

Specific embodiment

Reference picture 1-3, a kind of network filter housing with steam vent of the present utility model, including on lid 1 and base 2, There is in the middle of described base 2 cavity 5, cavity 5 surrounding is base wall 3, and the both sides of base wall 3 are provided with several PIN needle 4. The two ends of described base wall 3 are provided with the exhaust groove 6 to inner side depression, when base 2 and upper lid 1 cooperation, exhaust groove 6 Form steam vent and upper lid 1 between, steam vent is connected with the cavity 5 of base 2；Described exhaust groove 6 includes groove inner wall 61 And it is located at the recess sidewall 62 of groove inner wall 61 both sides, the apical side height of groove inner wall 61 is less than the apical side height of base wall 3.

After upper lid 1 and base 2 cooperation, between exhaust groove 6 and upper lid 1, form steam vent, for reaching maximum exhaust, preventing Only black glue solution blocks purpose, and groove inner wall 61 is obliquely installed, and forms outer aperture and be less than endoporus between exhaust groove 6 and upper lid 1 The steam vent of mouth.

Described groove inner wall 61 arranges outer chamfering structure with the junction of recess sidewall 62, and chamfering can also may be used for right angle Think fillet, by being arranged to chamfering structure, the inner chamber of base 2, when carrying out coiling, can reduce the abrasion that wire is formed. The top of recess sidewall 62 is arranged to the smooth structure of tilting simultaneously.

Exhaust groove 6 runs through whole base 2, and the lower end of usual base 2 is flanged structure, thus being also provided with flange portion Become concave inward structure, thus increasing the exhaust effect of whole exhaust groove 6.
