Wherein the guide slope includes: the protective cover comprises a first inclined plane and a second inclined plane, wherein the first inclined plane is positioned at the edge of the protective cover body, and the second inclined plane is in plane transition with the first inclined plane.
Specifically, the protective cover body is connected with the fixed part, the fixed part has the through-hole, the through-hole is used for through bolt.
Furthermore, the fixed part is including two, and two the fixed part is located respectively the diagonal angle setting of protective cover body.
When in actual application, the closed end of the protective cover body is of a chamfer structure.
The surface of the protective cover body and the surface of the fixing part are passivated by chromate or anodized.
Specifically, the outer wall surface of protective cover body reaches the surface of fixed part still adopts epoxy to mould powder plastic-blasting to handle.
Compared with the prior art, the protective cover of connector socket for high-speed train have following advantage:
the utility model provides an in the protective cover of connector socket for high-speed train, because the protective cover body adopts the die-casting aluminium material to make, the inner wall of protective cover body and the region with the sealing washer contact have the direction inclined plane, and this direction inclined plane can be used for making the sealing washer evenly get into the protective cover and by the inner wall extrusion of protective cover body, in order to produce contact pressure to effectively block leak passage and realize well sealed effect, consequently the utility model provides a protective cover of connector socket for high-speed train adopts the die-casting aluminium material with the weight that does not excessively increase the protective cover to through protective cover inner wall extrusion sealing washer in order to reach IP 67's protection level.

Detailed Description
For convenience of understanding, the following describes in detail a protective cover of a connector socket for a high-speed train according to an embodiment of the present invention with reference to the accompanying drawings.
An embodiment of the utility model provides a protective cover of connector socket for high-speed train, as shown in fig. 1 and fig. 3, include: adopt the protective cover body 10 that the die-casting aluminium material made, protective cover body 10's inner wall and the region of 2 contacts with sealing washer have direction inclined plane 11, and direction inclined plane 11 is used for making sealing washer 2 evenly get into the protective cover and by protective cover body 10's inner wall extrusion, with production contact pressure.
Compared with the prior art, the embodiment of the utility model provides a protective cover of connector socket for high-speed train have following advantage:
the embodiment of the utility model provides an among the protective cover of connector socket for high-speed train, because protective cover body 10 adopts the die-casting aluminium material to make, protective cover body 10's inner wall and with the region of sealing washer 2 contact have direction inclined plane 11, should lead inclined plane 11 and can be used for making sealing washer 2 evenly get into the protective cover and by protective cover body 10's inner wall extrusion, in order to produce contact pressure to effectively block leak passage and realize sealed effect well, consequently the embodiment of the utility model provides a protective cover of connector socket for high-speed train adopts the die-casting aluminium material with the weight that does not excessively increase the protective cover to through protective cover inner wall extrusion sealing washer 2 in order to reach IP 67's protection level.
As shown in fig. 2, the guide slope 11 may include: a first bevel 101 at the edge of the shield body 10 and a second bevel 103 that transitions from the first bevel 101 via a flat 102, so that the sealing ring 2 is better compressed and a more uniform contact pressure is generated.
