[0021] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0022] In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances. Example

[0024] like Figure 1 As shown, this embodiment provides a terminal crimping and positioning tool, including a main structure 1, a connecting portion and a contouring portion 2, wherein:

[0025] The connecting portion is arranged at one end of the main structure 1 and is used to connect the main structure 1 with the crimping die;

[0026] The profiling part 2 is slidably installed on the front side of the crimping mold installation side of the main structure 1. A terminal profiling groove 3 is provided on the side of the profiling part 2 away from the main structure 1. The terminal profiling groove 3 is adapted to one end of the terminal to be processed and is used to fix the terminal to be processed. The fixed terminal moves with the profiling part 2 toward or away from the crimping mold.

[0027] In the above technical scheme, due to the crimping characteristics of the crimping mold, if the direction of the terminal to be processed is wrong, it will affect the verification of electrical conductivity and the installation of the main engine factory, and it is very easy to cause defects during the crimping process, resulting in the scrapping or rework of the wiring harness. Therefore, in order to avoid the waste of man-hours caused by rework and the waste caused by scrapping, a terminal crimping positioning tool is used before the crimping process, and one end of the terminal to be processed is fixed by the terminal profiling groove to locate the crimping direction of the terminal. At the same time, through the sliding installation between the profiling part 2 and the main structure 1, the terminal to be processed can be adjusted in position according to the length of the processed wire with the profiling part 2, so as to avoid the inability to produce or the need for rework due to the wrong terminal crimping direction during assembly, thereby reducing labor costs and product scrapping and rework rates.

[0028] In some embodiments, in order to realize the sliding connection between the profiling part 2 and the column structure 1, it also includes a slider 4 and a slide rail 5. The slide rail 5 is fixed on the main structure 1. One end of the slider 4 is slidably connected to the slide rail 5, and the other end is fixed to the profiling part 2. The terminal installed on the terminal profiling groove 3 can be firmly fixed without shaking left and right, and can only move forward and backward according to the length of the processed wire.

[0029] In some embodiments, in order to facilitate the disassembly and assembly of the profiling portion 2 and replace the profiling portion with a terminal profiling groove 3 of different shapes and orientations to meet the crimping requirements of different terminals, the profiling portion 2 is detachably connected to the slider 4.

[0030] In some embodiments, in order to achieve a detachable connection between the contour part 2 and the slider 4, the contour part 2 and the slider 4 can be detachably connected by bolts, so that the need to replace the contour part 2 can be achieved by removing the bolts, but it is not limited to this, and other methods can also be used, such as: plug-in, snap-on, etc.

[0031] In some embodiments, in order to achieve an installation connection between the connecting part and the crimping mold, the connecting part includes a mounting hole 6 and a fastener. The mounting hole 6 is opened on the surface of the main structure 1. The mounting hole 6 is connected to the crimping mold through the fastener to install the main structure 1 on the outside of the cutting seat of the crimping mold.

[0032] In some embodiments, the fasteners include bolts, but are not limited thereto. The installation connection between the connecting portion and the pressing mold may also be achieved by other means, such as fixing with a metal clamp.

[0033] To sum up, the terminal crimping positioning tool provided in this embodiment fixes one end of the terminal to be processed through the terminal profiling groove to locate the crimping direction of the terminal. At the same time, through the sliding installation between the profiling part 2 and the main structure 1, the terminal to be processed can be adjusted in position according to the length of the processed wire along with the profiling part 2, so as to avoid production failure or rework due to incorrect terminal crimping direction during assembly, thereby reducing labor costs and product scrap rate and rework rate. Example

[0034] This embodiment provides a crimping mold equipped with the terminal crimping positioning tooling described in Example 1, which fixes one end of the terminal to be processed through the terminal profiling groove and can position the crimping direction of the terminal to avoid waste of work time caused by rework and waste caused by scrapping.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
