Therefore, the terms shall not be understood as limiting the utility model.

As shown inFIG.1toFIG.4, the invention relates to a supply clip of a terminal, which includes a guide rail1, wherein a top surface of the guide rail is provided with a sliding groove1ain a length direction of the guide rail, and two ends of the guide rail1are fixedly connected with a front baffle2and a rear baffle3respectively. The supply clip further includes a follow-up mechanism including a shell4having an open lower end. Notches4aare symmetrically arranged at a front side bottom and a rear side bottom of the shell4, and a length of the notch in a width direction of the guide rail1is slightly larger than a width of the guide rail1, so that the guide rail1is located in the notch with the shell4sheathed outside the guide rail1. The follow-up mechanism also includes a fixing column5arranged in the shell4in the width direction of the guide rail1. Two ends of the fixing column5are fixedly connected with a left side and a right side of the shell, respectively. A coil spring13is sheathed on an outer side wall of the fixing column5. An inner end of the coil spring is fixedly connected with the outer side wall of the fixing column5and an outer end of the coil spring penetrates out of the shell4through the notch and is fixedly connected at a position on a bottom of the sliding groove close to the front baffle2. The width of the coil spring is smaller than that of the sliding groove so that the outer end of the coil spring is located in the sliding groove and the shell4is pulled to move through the coil spring, and a top surface of the coil spring does not protrude from the sliding groove.

The supply clip of the terminal includes the guide rail1and the follow-up mechanism. A plurality of terminals are sequentially placed on the guide rail1in the length direction of the guide rail1. The bottom of each terminal is provided with a strip-shaped groove slidably clamped with the top surface of the guide rail1. Different terminals have different shapes, but the strip-shaped grooves on the bottoms of different terminals are the same so that the guide rail1is suitable for different terminals. The follow-up mechanism includes the shell4and the fixing column5, so that the lower end of the shell4is sheathed on the guide rail1through the notch in the shell4. The fixing column5is provided with the coil spring, and the outer end of the coil spring is fixedly connected at the position on the bottom of the sliding groove close to the front baffle2so that the terminal placed between the shell4and the front baffle2is pushed forwards. In an actual operation process, the plurality of terminals to be mounted are clamped on the guide rail1between the front baffle2and the follow-up mechanism through the strip-shaped grooves on the bottoms of the terminals. When one terminal closest to the front baffle2is pulled out upwards by a clamping jaw, the shell4is pulled through the coil spring, and the shell4pushes the remaining terminals to move forwards, so that the clamping jaw pulls out the terminals upwards at a same position continuously, thus providing automatic supply of the terminals. The action of pulling out the clamping jaw is a process of moving the terminals to be mounted upwardly. The terminals that are not pulled out are still firmly clamped on the guide rail1due to friction between the strip-shaped grooves on the bottoms of the terminals and the outer side wall of the guide rail1and will not be pulled out together to affect the action of sequentially pulling out the terminals upwards by the clamping jaw, thus improving a supply efficiency of the terminals.

In another embodiment of the supply clip of the terminal, a first opening is arranged on a top surface of the shell4close to the front side face, and a second opening communicated with the first opening is arranged on the front side of the shell4. A positioning mechanism arranged in the shell4is further included, and the positioning mechanism includes a rotating column6arranged in parallel with the fixing column5and located above the guide rail1. Two ends of the rotating column6are rotatably connected with the left side and right side of the shell4respectively. The rotating column6is provided with a through hole in a length direction of the rotating column and a central axis of the through hole does not coincide with a central axis of the rotating column6. Accordingly, a center of gravity of the rotating column6is not located on the central axis of the rotating column. A positioning column7is arranged on an outer side wall of the rotating column6in a radial direction of the rotating column, and an upper end of the positioning column7penetrates out of the shell4through the first opening or the second opening. A positioning block8is fixedly connected with the outer side wall of the rotating column6. The positioning block8is arranged as follows. When the positioning column7is located in the first opening, the positioning block8does not contact with the bottom of the sliding groove and the shell4is pulled to move on the guide rail1through the coil spring. When a force is applied to the positioning column7to enable the positioning column7to be located in the second opening, the positioning block8abuts against the bottom of the sliding groove so that the shell4does not move any more, and the shell4stands still at a position where the positioning block8abuts against the bottom of the sliding groove.

In another embodiment, the supply clip of the terminal further includes a limiting column9arranged in the shell4. The limiting column9is arranged in parallel with the fixing column5, and two ends of the limiting column9are fixedly connected with the left side and the right side of the shell4respectively. A sleeve is sheathed on an outer side wall of the limiting column9, and two ends of the sleeve are slidably clamped with the sliding groove, so that the sleeve is limited in the sliding groove. The sleeve can only move in the length direction of the sliding groove. Therefore, the sleeve4can only move in the length direction of the sliding groove to avoid deviation of the shell4.

In another embodiment of the supply clip of the terminal, a plurality of vertically arranged positioning rods10are fixedly arranged at a middle of the bottom of the guide rail1in a length direction of the guide rail. When the clip is in operation, the lower end of the positioning rod10is fixed on a fixing plate in a clip storage to ensure the stability of the clip, thus quickly supplying wiring terminals in an electrical cabinet assembly. Two pairs of rotating shafts11arranged in the shell4in the width direction of the guide rail1are further included. The two pairs of rotating shafts11are symmetrically arranged on two sides of the positioning rods10, respectively, and central axes of the two pairs of rotating shafts11are all located in the same horizontal plane. One end of the each of the two pairs of rotating shafts11are fixedly connected with a lower portion of an inner side wall of the shell4, respectively, and one roller12is sheathed on each of outer side walls of the other ends of the two pairs of rotating shafts11. A farthest distance between the two rollers12in the width direction of the guide rail1is slightly smaller than the width of the guide rail1so that when the shell4moves in the length direction of the guide rail1, the rollers12contact with the bottom of the guide rail1and roll in the length direction of the guide rail1.

In another embodiment of the supply clip of the terminal, the rear side face of the front baffle2is provided with a silica gel pad to avoid the terminal placed between the front baffle2and the shell4from colliding with the front baffle2under a pulling force of the coil spring from being damaged.

In another embodiment of the supply clip of the terminal, a top surface of the guide rail1is sprayed with a smooth paint layer to reduce friction between the shell4and the top surface of the guide rail1during running.
