With the development of today's industry, it is urgent to improve the consistency and stability of the crimping quality of such multi-connection insurance terminals. Utility Model Content

[0025] Traditional multi-connection insurance terminal crimping dies feed multiple terminals with multiple terminal pitches at one time. Since the multi-connection insurance terminal material has a certain elasticity, the material strip is very likely to elastically retreat after feeding, which will cause the crimping position of multiple terminals fed each time to be unstable, and it is easy to cause undesirable phenomena such as crimping dislocation and material strip blocking. With the development of today's industry, it is urgent to improve the consistency and stability of the crimping quality of such multi-connection insurance terminals.

[0026] Furthermore, the utility model proposes a directional anti-retraction device for the material channel of the multi-link insurance terminal crimping mold. Under the pressure of the spring, the limiting mechanism of the spring block in the material channel of the multi-link insurance terminal crimping mold will protrude a certain distance in the guide square hole of the baffle and be inserted into the material strip groove of the multi-link insurance terminal; because one side of the limiting mechanism is an inclined surface and the other side is a limiting surface perpendicular to the baffle surface, the multi-link insurance terminal can only move along the direction from the inclined surface to the limiting surface, preventing the terminal from elastically retreating, so that the terminal feeding position remains fixed, and the consistency and stability of the crimping quality of the multi-link insurance terminal is guaranteed; and, ensure that the crimping mold of the multi-link insurance terminal is stably and continuously produced at the production site, and greatly reduce the undesirable phenomena such as crimping dislocation and material strip blockage caused by unstable feeding position during the crimping process of the multi-link insurance terminal.

[0027] For example, Figure 1 A three-dimensional diagram of a directional stop device for a multi-connection insurance terminal crimping die according to an embodiment of the utility model, Figure 2 A three-dimensional schematic diagram of a multi-connection insurance terminal crimping die material channel directional anti-retraction device provided by an embodiment of the utility model. In the multi-connection insurance terminal crimping die material channel directional anti-retraction device provided by the utility model:

[0028] Reference Figure 1 and Figure 2 The material channel directional stop device of the multi-connection insurance terminal crimping mold includes: a feeding positioning plate 2, a feeding bottom plate 4, a multi-connection insurance terminal 5, a baffle 6, a spring block 7, a spring 8, a limit block 9, a third fastener 10, a fourth fastener 11, a second fastener 12, and a first through hole 13.

[0029] Among them, at least one first fastener 1 is provided on the feeding positioning plate 2 , and the feeding positioning plate 2 is fixed on the feeding bottom plate 4 through the at least one first fastener 1 .

[0030] Exemplarily, the first fastener 1 may be a screw; accordingly, the feed base plate 4 is provided with corresponding screw holes, so that the feed positioning plate 2 is fixed to the feed base plate 4 by at least one first fastener 1. The utility model does not specifically limit the type of the first fastener 1.

[0031] It can be understood that the feeding positioning plate 2 is used to keep the longitudinal position of the multi-connection fuse terminal 5 fixed during the feeding operation.

[0032] In a possible implementation, a material channel 15 is provided at the lower part of the feeding positioning plate 2 and passes through both sides, and the multi-connection insurance terminal 5 moves through the material channel 15. The specific positional relationship between the multi-connection insurance terminal 5 and the material channel 15 can be referred to Figure 1 .

[0033] Furthermore, a second fastener 12 is disposed on the baffle plate 6 , and a locking member 3 is correspondingly disposed on the feeding bottom plate 4 . The baffle plate 6 is fixed to the feeding bottom plate 4 through the locking member 3 and the second fastener 12 .

[0034] For example, the second fastener 12 may be a screw, and the locking member 3 may be a locking nut, specifically a hexagonal locking nut. Accordingly, a through hole for the screw to pass through may be provided on the baffle 6, and a limiting groove corresponding to the nut may be provided on the feeding bottom plate 4, so that the baffle 6 can be fixed to the feeding bottom plate 4 by the screw and the hexagonal locking nut. The utility model does not specifically limit the types of the second fastener 12 and the locking member 3.

[0035] The feeding bottom plate 4 is provided with corresponding screw holes, so that the feeding positioning plate 2 is fixed on the feeding bottom plate 4 by at least one first fastener 1. The utility model does not specifically limit the type of the first fastener 1.

[0036] The baffle plate 6 is also provided with a guide square hole 14 , which is used to cooperate with the spring block 7 described below to limit the multi-connection fuse terminal 5 .

[0037] Furthermore, a third fastener 10 is provided on the limiting block 9 , and the limiting block 9 is fixed on the baffle 6 via the third fastener 10 .

[0038] Illustratively, the third fastener 10 may be a screw; accordingly, the stop block 9 is provided with a corresponding screw hole, so that the stop block 9 is fixed to the baffle 6 through the third fastener 10. The utility model does not specifically limit the type of the third fastener 10.

[0039] Furthermore, the spring block 7 is provided with a countersunk hole 19 , and the stop block 9 is further provided with a first through hole 13 and a fourth fastener 11 . Thus, the fourth fastener 11 passes through the first through hole 13 and the spring 8 , and fixes the spring 8 on the spring block 7 .

[0040] Exemplarily, the fourth fastener 11 may be a screw, the first through hole 13 is a screw hole for matching the screw, and the countersunk hole 19 provided on the corresponding spring block is a screw hole, so that the screw passes through the first through hole 13 and the spring 8 to fix the spring 8 on the spring block 7.

[0041] It should be noted that the spring block 7 is inserted into the material strip groove of the multi-connection fuse terminal 5 through the guide square hole 14 .

[0042] In one possible implementation, referring to Figure 7 A limiting mechanism 16 is provided at the front end of the spring block 7. The vertical section of the limiting mechanism 16 is rectangular. The limiting mechanism (16) is pressed into the guide square hole (14) under the action of the spring (8), and contacts the multi-connection insurance terminal 5 in the material channel 15, and is further inserted into the groove of the multi-connection insurance terminal 5 material belt.

[0043] Specifically, refer to Figure 7 In the limiting mechanism 16, one side is an inclined surface 17, and the other side is a limiting surface 18. The limiting surface 18 is perpendicular to the contact surface between the limiting mechanism 16 and the rear end of the spring block 7, that is, perpendicular to the plane where the baffle 6 is located.

[0044] Reference Figure 7 When the spring 8 is in a compressed state, the elastic force of the spring 8 acts on the spring block 7, and the spring block 7 passes through the guide square hole 14 and protrudes a certain distance, so that the limiting mechanism 16 of the spring block 7 is just stuck in the groove of the material strip of the multi-gang insurance terminal 5. Therefore, when the multi-gang insurance terminal 5 moves to the right, the force is applied to the inclined surface 17, and the spring block 7 is forced to retreat, so that the spring 8 is further compressed, and then the multi-gang insurance terminal 5 can move normally to the right; at this time, the groove surface of the material strip of the multi-gang insurance terminal 5 is in contact with the limiting surface 18 of the spring block 7, and the multi-gang insurance terminal 5 cannot move to the left. As a result, the multi-gang insurance terminal 5 can only move along the direction from the inclined surface 17 to the limiting surface 18 under the action of the spring 8 and the spring block 7 ( Figure 7 The direction is right) and cannot move in the opposite direction ( Figure 7 The middle direction is left).

[0045] It is understandable that in actual production, if the multi-connection fuse terminal 5 needs to move in both directions, the elastic block 7 can be manually pulled out of the material strip groove of the terminal.

[0046] For example, the distance that the spring block 7 passes through the guide square hole 14 and protrudes can be 0.75 mm. In the actual production process, the size of the aforementioned distance can also be adjusted according to the specific size of the material strip of the multi-connection insurance terminal 5, and the utility model does not make specific restrictions on this.

[0047] Based on the above technical scheme, under the pressure of the spring, the limiting mechanism of the spring block in the directional anti-retraction device of the material channel of the multi-link safety terminal crimping mold provided by the utility model will protrude a certain distance in the guide square hole of the baffle and be inserted into the material strip groove of the multi-link safety terminal; because one side of the limiting mechanism is an inclined surface and the other side is a limiting surface perpendicular to the baffle surface, the multi-link safety terminal can only move along the direction from the inclined surface to the limiting surface, preventing the terminal from elastically retreating, so that the feeding position of the terminal remains fixed, thereby ensuring the consistency and stability of the crimping quality of the multi-link safety terminal; and ensuring that the crimping mold of the multi-link safety terminal can be stably and continuously produced at the production site, and greatly reducing the undesirable phenomena such as crimping dislocation and material strip blockage caused by unstable feeding position during the crimping process of the multi-link safety terminal.
