Fig. 1 to 3 show a structure of a connection terminal according to an embodiment of the present invention. Fig. 4 and 5 are schematic views showing a crimping process of a cable using the terminal of the present embodiment. As shown in fig. 4, the cable 4 includes an insulating sheath 401 and a wire core 402 wrapped in the insulating sheath 401. When it is desired to crimp the cable 4, the insulation 401 at the end thereof is removed to expose the inner wire core 402 and the wire core 402 is placed on the terminal.
As shown in fig. 1, a connection terminal according to an embodiment of the present invention includes:
a terminal main body 1; and
When the wiring terminal of the embodiment is used, the wire core 402 of the cable 4, from which the insulating sheath 401 is removed, is placed in the accommodating space formed by enclosing the wire pressing piece 3 and the terminal body 1, then the second end of the wire pressing piece 3 is moved towards the direction far away from the terminal body 1, and the accommodating space formed by enclosing the wire pressing piece 3 and the terminal body 1 is gradually reduced in the process, so that the fastening and crimping of the cable are realized. The wiring terminal provided by the embodiment of the invention can realize wire pressing without using a special wire pressing tool.
In some embodiments, as shown in fig. 1, when the crimping pieces 3 are in an initial state (no crimping), the crimping pieces 3 are arc-shaped. Because wire sinle silk 402 is generally circular, in the in-process that the second end of line ball piece 3 removed, curved line ball piece 3 can keep the contact and the crimping with wire sinle silk 402 better, guarantees the crimping effect to the cable.
As shown in fig. 4 and 5, compared with the cable pressing piece 3 in the initial state, the cable pressing piece 3 deforms in the moving process so that the accommodating space enclosed by the cable pressing piece 3 and the terminal body 1 becomes smaller and the cable pressing effect is achieved.
The connecting terminal of the present embodiment further includes a driving structure for driving the second end of the wire pressing piece 3 to move. The driving structure may be a linear moving structure connected to the wire pressing piece 3, or a rotating structure connected to the wire pressing piece 3, as long as the driving structure drives the second end of the wire pressing piece 3 to move in a direction away from the terminal body 1.
In the present embodiment, as shown in fig. 1 and 2, the terminal further includes an annular housing 2. The annular housing 2 is disposed outside the terminal body 1 and connected to the second end of the wire pressing piece 3, and the annular housing 2 rotates in one direction relative to the terminal body 1 to drive the second end of the wire pressing piece 3 to move. Specifically, the annular housing 2 is controlled to rotate counterclockwise to drive the second end of the wire pressing piece 3 to move in the direction away from the terminal body 1, so that the shape and size of the accommodating space formed by enclosing the wire pressing piece 3 and the terminal body 1 are changed.
The annular housing 2 of the present embodiment is completely closed in the circumferential direction. In other embodiments, the annular housing may also have a notch, so long as the annular housing can rotate in one direction and drive the second end of the wire pressing piece 3 to move.
To facilitate the operation and control of the rotation of the annular housing 2, as shown in fig. 3, the axial end of the annular housing 2 is provided with a handle 204. The handle 204 is used to apply an external force to rotate the ring housing 2. Preferably, the annular housing 2 of the present embodiment is provided with handles 204 on both sides to facilitate rotation of the annular housing 2 at different positions.
When the operation space is insufficient or inconvenient axially outside the annular housing 2, the annular housing 2 may also be rotated by inserting a tool into the through-hole 202 provided on the annular housing 2. As shown in fig. 3, the annular housing 2 of the present embodiment is provided with at least one through hole 202 in the circumferential direction so as to facilitate the rotation of the annular housing 2 at different positions.
In some embodiments, as shown in fig. 2, the inner surface of the annular housing 2 is uniformly arranged with a plurality of first card slots 201 in the circumferential direction. Both sides of the terminal body 1 are provided with first latches 104. The first card slot 201 cooperates with the first latch 104 to allow the ring housing 2 to rotate unidirectionally with respect to the terminal body 1. Terminal body 1 is fixed to be set up, and at annular housing 2 rotation in-process, a plurality of first draw-in grooves 201 of annular housing 2 and the first latch 104 cooperation that terminal body 1 both sides set up, these two first latches 104 support annular housing 2 in order to guarantee its rotation stationarity at annular housing 2's rotation in-process. The terminal achieves the support of the annular housing 2 by using the terminal body of the terminal, and no redundant support structure is arranged, so that the structure of the terminal is simplified.
Also, the first engaging groove 201 and the first engaging tooth 104 of the present embodiment are both inclined toward the side of the rotational direction of the ring housing 2. Specifically, in the present embodiment, the annular housing 2 rotates counterclockwise, and the first card slot 201 inclines in the counterclockwise direction. As shown in fig. 2, the first latch 104 on the left side of the terminal body 1 is inclined toward the lower side. The first latch 104 located on the right side of the terminal body 1 is inclined toward the upper side. The arrangement can avoid the annular shell 2 from rotating in the opposite direction to influence the crimping effect on the cable.
In other embodiments, the annular housing may also be rotated clockwise. Referring to fig. 2, for example, the left end of the wire pressing piece 3 may be fixed, and the right end may pass through the terminal body 1 and be movable in a direction away from the terminal body 1 with respect to the terminal body 1. At this time, the annular housing 2 can rotate clockwise and drive the right end of the line pressing piece 3 to move. In this embodiment, the first engaging groove and the first engaging tooth are inclined in the clockwise direction to prevent the annular housing 2 from rotating in the reverse direction.
In order to limit the movement of the wire pressing piece 3 to prevent the wire pressing piece from retracting reversely, the outer surface of the wire pressing piece 3 of this embodiment is uniformly provided with a plurality of second slots 301, a channel for the second end of the wire pressing piece 3 to pass through is provided in the terminal body 1, and a second latch (not shown in the figure) matched with the second slots 301 is provided in the channel. The second latch and the second slot 301 provided inside the terminal body 1 form a concave-convex position so that the second end of the wire pressing piece 3 moves in one direction relative to the terminal body 1.
Specifically, the second engaging groove 301 of the present embodiment is inclined toward the second end of the crimping piece 3, and the second engaging tooth is inclined downward. The second clamping groove 301 and the second clamping teeth are obliquely matched to prevent the wire pressing piece 3 from moving reversely, so that the cable is locked and fastened.
In order to reduce the acting force applied to the rotation of the annular housing 2, the number of the first card slots 201 is larger than that of the second card slots 301. The number of the first card slots 201 is proportional to the number of the second card slots 301.
