Generally, the output that lays along the Px direction is three at most, because the volume is many, can corresponding increase binding post along the size of Px direction, when embracing the pole installation with this binding post like this, partial binding post can not hug closely with the bracing piece, and then can increase the windward area, reduces the stability of installing the binding post on the bracing piece.
With the development of optical networks, the number of optical distribution cables is required to be increased, and thus, the number of output terminals arranged on one terminal is increased, so that a high-density output terminal is formed.
In order to realize high-density arrangement of output ends, when the wiring terminal shown in fig. 1 is adopted, the length size of the wiring terminal is increased to increase the number of the output ends, so that the length size of the wiring terminal is larger, and usually, the space reserved for the wiring terminal on the supporting rod is limited, so that when the length size of the wiring terminal is larger, the wiring terminal is difficult to install on the supporting rod.

Detailed Description
The embodiments of the present application relate to a connection terminal and a transmission device, and the connection terminal and the transmission device are described in detail below with reference to the accompanying drawings.
It should be noted that: the connection Terminal of the present application may also be referred to as a junction Box, a connection Terminal Box (CBT), a Terminal connection Box (SSC), a Fiber optic cable Access Terminal (FAT), and the like.
In one aspect, an embodiment of the present application provides a terminal, and referring to fig. 2a, the terminal includes: a
That is to say, the present application provides a plurality of output ends disposed on the first side surface and the second side surface, and compared with the prior art in which the output ends are disposed on only one surface (surface), the technical effects that: under the condition that the length dimension (as shown in the direction of P2 in fig. 2 a) of binding post is equal, this application can be obvious increases the quantity of output, and then realizes under the condition that the length dimension of binding post can not increase more, realizes the high density of output and lays.
In addition, because the distance between the first side surface and the second side surface is gradually reduced along the direction from the fixing surface to the surface, compared with the scheme that the distance between the first side surface and the second side surface is not changed along the direction from the fixing surface to the surface, under the condition that the thickness sizes (such as the P1 direction shown in fig. 2 b) of the connecting terminals are equal, the first side surface and the second side surface have larger areas, and thus, the number of output end layouts is correspondingly increased, so that high-density layout is realized.
It should be noted that: the "first side a1 and second side a2 are opposite" in the "first side a1 and second side a2 are opposite and located on both sides of the third side A3" described herein means that: the perpendicular projection of the first side a1 on the second side a2 occupies at least a portion of the second side a 2.
In specific implementation, generally, after the wiring terminal is fixed on a support rod or a wall surface or other structures, the output cable is installed on the output end, and because the number of the output ends on one wiring terminal is large, the number of the connected output cables is large, so that the convenience for an operator to install the output cables is also an important index for determining the service performance of the wiring terminal.
In order to improve the usability of the terminal, referring to fig. 3b and 7a, the distance between the first side a1 and the second side a2 is gradually reduced along a direction perpendicular to the third side A3 (the P2 direction shown in fig. 3b and 7 a) and from far away from the third side A3 to near the third side A3. In this way, compared with fig. 3a, the first side a1 and the second side a2 are inclined toward the input end, so that when an operator stands near one position to install the input cables, all the input cables can be installed, and the operability of the connection terminal is improved.
The distance between the first side a1 and the second side a2 gradually decreases in the direction of P2 as shown in fig. 3b and 7a, and there are two different embodiments, which are explained separately below.
