Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, the present embodiment discloses a filter 100 with an anti-static function, and the filter 100 with an anti-static function includes a housing 10, an end cap 20, an anti-static body 50, a connector 60, and a first external terminal 30 and a second external terminal 40 respectively mounted on opposite outer surfaces of the housing 10. End cap 20 is removably mounted to open end 12 of housing 10. The connecting member 60 includes a bottom plate 61 and side plates 62 respectively connected to both sides of the bottom plate 61, and opposite surfaces of the two side plates 62 are each configured with an insertion groove 63. The base plate 61 is mounted to the inner wall 11 of the housing 10. The antistatic body 50 is transversely arranged and is in plug fit with the slot 63.

With the above scheme, the filter 100 with the anti-static function of the embodiment has the following beneficial effects: the antistatic body 50 is provided on the inner wall 11 of the housing 10, so that the antistatic effect of the filter can be improved.

Because the anti-static body 50 is arranged in the shell 10, the anti-static body is not easy to be polluted by dust, is not easy to corrode and has longer service life.

When the anti-static body 50 is installed, the end cap 20 is opened, and the anti-static body 50 is inserted into the insertion slot 63. Therefore, the filter 100 having the anti-static function of the present embodiment also has an advantage of convenience in mounting the anti-static body 50.

When the anti-static body 50 is detached, the end cap 20 is opened, and the anti-static body 50 is pulled out from the insertion groove 63. Therefore, the filter 100 having the anti-static function of the present embodiment also has an advantage of convenience in detaching the anti-static body 50.

The transverse direction is shown as the X direction in fig. 1, and the longitudinal direction of the housing 10, the extending direction of the slot 63, and the longitudinal direction of the antistatic body 50 all coincide with the transverse direction.

Specifically, the housing 10 and the end cap 20 may be snap-fit or screwed or bolted together. Other removable connections between the housing 10 and the end cap 20 may be used.

Preferably, the number of the connecting members 60 is at least two, and at least two connecting members 60 are laterally spaced apart.

As shown in fig. 2, it is preferable that the number of the connecting members 60 is two, which can satisfy the requirement of installing the static electricity preventing body 50 while saving parts.

Preferably, the length of the antistatic body 50 is greater than the distance between any two connection members 60. Specifically, two connectors 60 are provided near the open end 12 of the housing 10 to facilitate installation of the connectors 60.

Preferably, both side plates 62 are inclined toward a direction away from each other so as to increase a distance between the opposite insertion grooves 63, so that the insertion grooves 63 of the connection member 60 can receive the wider antistatic body 50. The included angle between the side plate 62 and the bottom plate 61 is preferably greater than 90 degrees and not greater than 130 degrees.

Preferably, two convex plates 64 are arranged on the opposite surfaces of the two side plates 62, and the two convex plates 64 and the side plates 62 enclose the slot 63. The raised panel 64 is perpendicular to the side panel 62, so that the existing material can be used as the side panel 62. The width of the protruding plate 64 may be selected according to the actual situation so that the antistatic body 50 does not fall off from the connecting member 60. There is no contact between the two opposing flanges 64, which is beneficial in saving material.

Preferably, the bottom plate 61 is welded to the two side plates 62.

Preferably, the base plate 61 is opened with a mounting hole, and the base plate 61 is mounted to the inner wall 11 of the housing 10 by a screw.
