Embedded laminated terminal injection molding part

Abstract

The utility model relates to an embedded laminated terminal injection molding part, which comprises a plurality of laminated terminals, a low-pressure molded first injection molding material is arranged between the adjacent terminals, and the low-pressure molded injection molding material supports and insulates the adjacent terminals. The periphery of the terminal and the first injection molding material is wrapped with a second injection molding material formed by high pressure. Since the first injection molding material formed by low-pressure molding is arranged between the adjacent terminals in advance, during high-pressure injection molding, in the process that the second injection molding material wraps the terminals and the first injection molding material to form the injection molding part, due to the supporting and insulating effects of the first injection molding material, the terminal and the first injection molding material are not easy to deform; the high voltage does not eliminate the gap between the adjacent terminals so as not to cause abnormal electrical insulation.

Description

Technical Field

[0001] The utility model relates to an injection molded part, in particular to an injection molded part with embedded laminated terminals. Background Art

[0002] When producing multi-layer embedded terminal products, the terminals need to be placed in a mold before injection molding. There is a gap between the upper and lower terminals due to the electrical insulation withstand voltage requirements. Therefore, the terminals may be affected by the injection pressure, which may cause the upper and lower terminals to contact, resulting in abnormal electrical insulation withstand voltage. Utility Model Content

[0003] The utility model aims to provide an embedded laminated terminal injection molding, which solves the problem of how to avoid abnormal electrical insulation between terminals.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] The utility model provides an embedded laminated terminal injection molding, which comprises a plurality of stacked terminals, wherein a first low-pressure molded injection molding material is arranged between adjacent terminals, the low-pressure molded injection molding material forms support and insulation between adjacent terminals, and the terminal and the first injection molding material are wrapped with a second high-pressure molded injection molding material on their outer periphery.

[0006] Preferably, the first injection molding material is arranged above and / or below the terminals clamped in the middle layer of the stacked terminals.

[0007] Furthermore, the first injection molding material is disposed above and below the terminals clamped in the middle layer among the stacked terminals only in the areas overlapping with the upper or lower terminals.

[0008] Furthermore, the first injection plastic and the second injection plastic clamped above the terminals in the middle layer of the stacked terminals are connected at the side through a connecting portion.

[0009] Furthermore, the connecting portion is a rod-shaped body distributed at multiple points.

[0010] Preferably, the first injection molding material also extends into the opening of the terminal.

[0011] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0012] The embedded laminated terminal injection molded part of the utility model has a first injection material formed by low-pressure molding pre-arranged between adjacent terminals. Therefore, during high-pressure injection molding, in the process of the second injection material wrapping the terminal and the first injection material to form the injection molded part, due to the support and insulation effect of the first injection material, the high pressure will not eliminate the gap between the adjacent terminals to cause electrical insulation abnormality.

[0022] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention 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 limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0024] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] like Figure 1 In the embedded laminated terminal injection molded part shown, the second injection material 6 wraps the terminal through injection molding, and a portion of the terminal is exposed.

[0026] like Figure 2 As shown, and refer to Figure 6 The terminal is a plurality of stacked terminals, including, from top to bottom, a first terminal 1, a second terminal 2, a third terminal 3, and a fourth terminal 4. Figure 6 , between adjacent terminals is a supporting isolator formed by the first injection molding material 5.

[0027] like Figure 6 and Figure 4 , the first injection plastic 5 is arranged above and below the second terminal 2, and the first injection plastic 5 above and below is connected by a lateral connection part 7, and the connection part 7 is a rod-shaped body distributed at multiple points. Of course, the connection part 7 can also be other shapes. Figure 6 and Figure 5 A first injection plastic 5 is disposed below the third terminal 3 , and an opening is provided in the third terminal 3 , and the first injection plastic 5 extends into the opening.

[0028] like Figure 3 As shown, the first injection plastic 5 is injected by a low pressure molding machine to encapsulate the second terminal 2 and the third terminal 3. The first injection plastic 5 is supported between adjacent terminals, so that when several terminals are simultaneously injected by the second injection plastic 6 to form a product, the high pressure will not eliminate the gap between adjacent terminals, resulting in abnormal electrical insulation withstand voltage.

[0029] like Figure 6 As shown, the first injection molding material 5 below the third terminal 3 is only arranged in the overlapping area between the third terminal 3 and the fourth terminal 4 .

[0030] In this example, when the first injection plastic only needs to be injected onto the second terminal 2 and the third terminal 3, there is no need to perform low-pressure injection molding on the first terminal 1 and the fourth terminal 4. In other implementations, other terminals can also be selected for low-pressure injection molding, such as injecting the first injection plastic below the first terminal 1, the second terminal 2, and the third terminal 3, as long as the first injection plastic exists between adjacent terminals when the terminals are stacked.

[0031] In summary, in the embedded laminated terminal injection molding of this example, since the first injection plastic is set between adjacent terminals, the first injection plastic is first injected on the upper and lower surfaces of the second terminal 2 and below the third terminal 3 by a low-pressure molding machine. The first injection plastic is supported between the adjacent terminals, so that when the second injection plastic is injected, the gap between the adjacent terminals will not be eliminated due to high pressure.

[0032] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
