[0012] Compared with the prior art, this utility model provides a pre-injection molded structure for a single row of fisheye terminals in a connector, which has the following advantages:

[0013] 1. The single-row fisheye terminal pre-injection molding structure of this connector, through secondary pre-injection molding, can perform initial positioning of the terminal body, effectively preventing deformation after bending of the terminal body. This allows the pre-molded semi-finished terminal body to be smoothly inserted into the finished product mold, shortening the production cycle, significantly improving production efficiency, and effectively solving defects such as inconsistent terminal body length, exposed terminal body, short circuit, and poor airtightness.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a pre-injection molding structure for a single row of fisheye terminals of a connector, including a finished mold 1, a first pre-injection molded part 2 inserted inside the finished mold 1, a second pre-injection molded part 3 embedded inside the first pre-injection molded part 2, and a terminal body 4 disposed inside the second pre-injection molded part 3.

[0021] After secondary pre-injection molding, the terminal body 4 can be initially positioned, effectively preventing deformation after bending. This allows the pre-molded semi-finished terminal body 4 to be smoothly inserted into the finished product mold 1, shortening the production cycle, significantly improving production efficiency, and effectively solving defects such as inconsistent length of the terminal body 4, exposed terminal body 4, short circuit, and poor airtightness. At the same time, the device is assembled from multiple structures. When a defective product appears in one of the structures, only the semi-finished product needs to be scrapped, greatly reducing scrap costs.

[0022] To prevent severe deformation of the coiled material and insufficient quantity of the terminal body 4 after bending, this invention provides an insertion connection between the terminal body 4 and the second pre-injection molded part 3. This effectively prevents severe deformation of the coiled material and insufficient quantity of the terminal body 4 after bending. At the same time, it also provides additional fixation for the cutting and bending of the second pre-injection molded part 3 after injection molding, ensuring that the terminal body 4 remains a single unit without deformation after cutting and bending.

[0023] In order to prevent defects such as exposed terminal bodies 4 and short circuits between adjacent terminal bodies 4 caused by excessive local glue thickness, insufficient injection filling, and inadequate positioning of the first pre-injection molded part 2, this utility model incorporates the bent terminal body 4 and the second pre-injection molded part 3 as inserts into the interior of the first pre-injection molded part 2. This effectively prevents defects such as exposed terminal bodies 4 and short circuits between adjacent terminal bodies 4 caused by excessive local glue thickness, insufficient injection filling, and inadequate positioning of the first pre-injection molded part 2.

[0024] In order to significantly reduce the generation of defective products, this utility model uses the first pre-injection molded part 2 as an insert to be implanted into the interior of the finished product mold 1. Therefore, the generation of defective products can be significantly reduced, production efficiency can be effectively improved and scrap costs can be effectively reduced.

[0025] To facilitate the installation of the finished product mold 1 by workers, this utility model provides four sets of mounting holes at the bottom of the outer side of the finished product mold 1. These mounting holes allow workers to pass screws through them and then use a designated tool to tighten them, ultimately rotating the bottom of the screw into the screw hole at the designated installation position, thus installing the finished product mold 1. This process involves fewer steps, saves time and effort, and facilitates the installation of the finished product mold 1 by workers.

[0026] In use, the operator first uses designated equipment to injection mold the second pre-molded part 3 and the temporarily unbent terminal body 4 into a single unit, so that the unbent terminal body 4 is inserted into the interior of the second pre-molded part 3, such as... Figure 4 As shown, the specified tool is then used to bend the unbent terminal body 4 at a specified location, as follows: Figure 3 As shown, the bent terminal body 4 and the second pre-injection molded part 3 are then injection molded together with the first pre-injection molded part 2 as a whole, so that the bent terminal body 4 and the second pre-injection molded part 3 are embedded into the interior of the first pre-injection molded part 2 as a whole, as shown. Figure 2 As shown, the three injection-molded components are then inserted into the finished product mold 1, thus completing the production of the product. Figure 1 As shown.

[0027] The dimensions and shapes of all components in this structure are not specifically limited here and need to be produced according to the actual situation.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
