TECHNICAL FIELD
The present invention relates to the field of communications technologies, and in particular, to an access terminal box component.
BACKGROUND
A mounting plate of an access terminal box is a mounting accessory of the access terminal box and has a wide range of application scenarios. The mounting plate is configured to be assembled on the access terminal box, so as to mount the access terminal box on a specified position. The mounting plate may support wall-hung mounting, in-wall mounting, and dedicated slide mounting in a cabinet or a chassis, and may also support mounting by directly attaching the mounting plate to a wall by using an adhesive tape. Specifically, when the access terminal box is being mounted, it is required to first fasten the access terminal box on the mounting plate and then fasten the mounting plate on a specified position. However, when it is required to detach the access terminal box from the mounting plate, it is required to manually separate a mounting member on a base of the access terminal box. As a result, a detaching operation is inconvenient, and when a separating force is too large, damage is caused to a part on the base of the access terminal box. In addition, because a large quantity of fibers are coiled on the base of the access terminal box, when the separating force is too large during detachment, a fiber may be touched, which causes damage to the fiber.

The cover body 210 is configured to cover the fiber optic terminal base 20. The cover body 210 includes a first side wall 211 and a second side wall 212 that are arranged opposite to each other. A first accommodating notch 213 corresponding to the first pressing part 23 is formed on the first side wall 211. A second accommodating notch 214 corresponding to the second pressing part 24 is formed on the second side wall 212. When the cover body 210 covers the fiber optic terminal base 20, the first pressing part 23 is accommodated inside the first accommodating notch 213, an end face of the first pressing part 23 is exposed to the outside, the second pressing part 24 is accommodated inside the second accommodating notch 214, and an end face of the second pressing part 24 is exposed to the outside.
It should be noted that, when the cover body 210 covers the fiber optic terminal base 20, the first pressing part 23 is accommodated inside the first accommodating notch 213, the end face of the first pressing part 23 is exposed to the outside, the second pressing part 24 is accommodated inside the second accommodating notch 214, and the end face of the second pressing part 24 is exposed to the outside, so as to help an operator press the first pressing part 23 and the second pressing part 24 by directly contacting the first pressing part 23 and the second pressing part 24, so that the first pressing part 23 and the second pressing part 24 deform to drive the hooking part of the first locking hook 21 and the hooking part of the second locking hook 22 to respectively detach from the corresponding engaging grooves. Therefore, functions of the first accommodating notch 213 and the second accommodating notch 214 are helping the operator conveniently perform a pressing operation on the first pressing part 23 and the second pressing part 24.
Further, the end face of the first pressing part 23 and an outer surface of the first side end face 25 are on a same plane. The end face of the second pressing part 24 and an outer surface of the second side end face 26 are on a same plane. When the fiber optic terminal base 20 is mounted on the mounting plate 10 and the cover body 210 covers the fiber optic terminal base 20, a surface of each side of the mounting plate 10, an outer surface of a corresponding end face of the cover body 210, and an end face of a corresponding pressing part are all on a same plane. Therefore, the access terminal box component 200 has no irregular edges, so that space for mounting the access terminal box 200 is reduced.
Finally, it should be noted that the foregoing embodiments are merely intended for describing the technical solutions of the present invention, but not for limiting the present invention. Although the present invention is described in detail with reference to the foregoing embodiments, a person of ordinary skill in the art should understand that the descriptions are not intended to limit the protection scope of the present invention. Any variation or replacement readily figured out by a person skilled in the art within the technical scope disclosed in the present invention shall fall within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
