Summary of the invention

The purpose of this utility model is to provide a kind of electronic equipment cable connecting device, to overcome the not good enough shortcoming of water resistance in the prior art.

The electronic equipment cable connecting device that the utility model adopted, comprise wire clamp and equipment coverboard, wherein, described wire clamp comprises a clamping block, be embedded with Stranded cable in this clamping block, many heart yearns of encapsulation in the per share cable, described clamping block connects a flange piece, offer connecting hole on this flange piece, and have a flange face;

Offer the notch identical with the gabarit of clamping block on the described equipment coverboard, described notch outward flange has a buckling surface, offers screw on the described buckling surface;

Described flange face and buckling surface fit, and screw passes connecting hole and links to each other with screw, it is characterized in that: card is established a circle triangle rib between described flange face and the buckling surface, and described triangle rib closed-loop is around notch.

Described triangle rib is attached on the buckling surface.

Described triangle rib and buckling surface are a body component.

The beneficial effects of the utility model are: in the utility model, wire clamp comprises a clamping block, be embedded with Stranded cable in this clamping block, many heart yearns of encapsulation in the per share cable, clamping block connects a flange piece, offer connecting hole on the flange piece, and has a flange face, offer the notch identical on the equipment coverboard with the gabarit of clamping block, the notch outward flange has a buckling surface, offer screw on the buckling surface, card is established a circle triangle rib between flange face and the buckling surface, and triangle rib closed-loop is around notch, like this, when flange face and buckling surface fit, utilize the strain of triangle rib or flange face/buckling surface, the triangle rib has played the effect of eliminating the gap between flange face and buckling surface, and closed-loop is isolated from aqueous vapor outside the triangle rib fully around the triangle rib of notch, that is aqueous vapor can't penetrate into electronic equipment internal from the gap between flange face and the buckling surface, thereby makes the utility model obtain good water resistance; From another point of view, for obtaining (with prior art) suitable water resistance, the utility model is relatively reduced for machining accuracy, the technological requirement of flange face/buckling surface, helps reducing cost.

In the utility model, the triangle rib is attached on the buckling surface, and triangle rib and buckling surface are a body component, have further improved reliability of the present utility model and practicality.
