Abstract
Description
Technical Field
[0001] This application relates to a plug connector, and more particularly to a plug connector having multiple width variations on the connector body. Background Technology
[0002] A connector is a general term for all connecting components and accessories used in the transmission of electronic signals and power. Its main function is to establish and maintain connections between circuits. It is responsible not only for transmitting power but also for transmitting data. It is an important component in any modern electronic system. From mobile phones and computers to large industrial machinery, everything relies on connectors to complete its basic functions.
[0003] Taking a power connector as an example, it typically consists of metal terminals and a plastic housing, with the metal terminals mounted within the plastic housing for power transmission. To ensure good electrical contact, the metal terminals must be fixed within the terminal slot to prevent movement or displacement during connection or disconnection, which could lead to poor contact or power failure. However, as electronic devices become increasingly smaller, power connectors are also being designed to be thinner and lighter. This design philosophy increases the difficulty of designing the mechanism within the plastic housing to hold the metal terminals, or the mechanism may be too weak to provide adequate fixation. Therefore, how to improve these issues is a major topic discussed in this application. Utility Model Content

[0012] Optionally, the connector body has multiple insertion portions, and each insertion portion is provided with a front opening and an insertion portion space.
[0013] Another object of this application is to provide a plug connector having multiple terminal slots of varying widths, comprising a connector body as described above and at least one metal terminal. Each of the metal terminals is respectively mounted into each of the corresponding terminal slots and each of the mating portions.
[0014] Optionally, the metal terminal includes at least one wing that is elastic, can be installed into the terminal slot, and its end is forced against the inner wall of the narrow slot region of the terminal slot and applies an unfolding force to the inner wall of the narrow slot region.

Figure 1 The lower right of the axis is defined as the right side of the component; the vertical axis (Y-axis) refers to the forward and backward extension direction, where... Figure 1 The lower left corner serves as the rear side of the component. Figure 1 The upper right of the axis is used as the front direction of the component; the vertical axis (Z-axis) refers to the vertical extension direction. Figure 1 The area above is considered the top (top) side of the component. Figure 1 The area below is used as the bottom (bottom) side direction of the component.
[0029] Please see Figures 1 to 3 As shown, in one embodiment, the plug connector C includes a connector body 1 and at least one metal terminal 2, and the metal terminal 2 can be assembled into the connector body 1. Depending on product requirements, the metal terminal 2 can be single or multiple, and its type can be one of power terminal, signal terminal, or ground terminal. When the plug connector C has multiple metal terminals 2, the types of the multiple metal terminals 2 can be exactly the same, or a mixture of multiple types. Furthermore, to avoid overly complex diagrams, only a portion of the metal terminals 2 are shown in the diagrams.
[0030] In this embodiment, please refer to Figures 1 to 4 As shown, the connector body 1 includes a base 11 and at least one insertion portion 13. The base 11 has at least one terminal slot 111, and the terminal slot 111 forms a corresponding rear opening 113 on the rear side of the base 11. In other words, as shown... Figure 2 and Figure 5 As shown, the shape of the rear opening 113 (viewed from the rear) is approximately the same as or adjacent to the cross-sectional shape of the terminal slot 111. Furthermore, the terminal slot 111 is divided into a narrow slot region 111A, a transition region 111B, and a wide slot region 111C. The maximum transverse width of the narrow slot region 111A is smaller than the maximum transverse width of the wide slot region 111C. The transition region 111B connects the narrow slot region 111A and the wide slot region 111C, and its transverse width gradually increases from the narrow slot region 111A towards the wide slot region 111C. This increase in width can be linear or non-linear.
[0031] Please refer to the above. Figure 4 and Figure 5As shown, at least one wall of the terminal slot 111 includes a first vertical segment 1111, a second vertical segment 1112, and a transition segment 1113. The first vertical segment 1111 and the second vertical segment 1112 both extend along a vertical axis, but their corresponding vertical axis positions are different. In other words, the extension directions of the first vertical segment 1111 and the second vertical segment 1112 do not coincide on the vertical axis. Furthermore, the transition segment 1113 connects the first vertical segment 1111 and the second vertical segment 1112. In this embodiment, the two opposite walls of the same terminal slot 111 (e.g., the left and right walls) respectively include a first vertical segment 1111, a second vertical segment 1112, and a transition segment 1113. The two first vertical segments 1111 of the plurality of walls are opposite each other, the two second vertical segments 1112 of the plurality of walls are opposite each other, and the two transition segments 1113 of the plurality of walls are opposite each other.
[0032] Please refer to the following: Figures 1 to 5 As shown, in this embodiment, the base 11 has 12 terminal slots 111, which are arranged in two rows along the horizontal axis, with each row containing six terminal slots 111. Viewed from the rear, the shapes of the rear openings 113 of two adjacent terminal slots 111 in the same row are opposite to each other. Specifically, taking the two rightmost adjacent terminal slots 111 in the same row as an example, the narrow slot region 111A of the left terminal slot 111 is opposite to the wide slot region 111C of the right terminal slot 111; the wide slot region 111C of the left terminal slot 111 is opposite to the narrow slot region 111A of the right terminal slot 111; the transition region 111B of the left terminal slot 111 is opposite to the transition region 111B of the right terminal slot 111. The remaining terminal slots 111 in the same row are arranged in the same manner. Furthermore, the two rows of terminal slots 111 are arranged along the vertical axis, and adjacent terminal slots 111 located on the same vertical axis have substantially the same shape in terms of their rear openings 113 when viewed from the rear. It is worth noting that, depending on the actual needs of the product, the base 11 may have only a single row of multiple terminal slots 111; or, the base 11 may have only two vertically arranged terminal slots 111; furthermore, the number of the multiple terminal slots 111 will be substantially the same as the number of metal terminals 2 (but not limited thereto). In some embodiments, in two adjacent terminal slots 111 arranged along the horizontal axis, the horizontal height H1 of the top of the narrow slot region 111A of one terminal slot 111 (e.g., the left terminal slot 111) will be lower than the horizontal height H2 of the top of the wide slot region 111C of the other terminal slot 111 (e.g., the right terminal slot 111), but this is not a limitation; in other embodiments, the top horizontal heights of the two adjacent terminal slots 111 can remain flush.
[0033] Additionally, please refer to Figures 1 to 5As shown, in this embodiment, the connector body 1 has a plug-in portion 13, which is integrally formed on the front side of the base 11. The front side of the plug-in portion 13 has multiple front openings 130, each containing multiple plug-in spaces 132. Each plug-in space 132 communicates with a corresponding front opening 130 and a terminal slot 111, but this is not a limitation. In other embodiments of this application, the connector body 1 can have multiple independently spaced plug-in portions 13, and each plug-in portion 13 has a front opening 130 and a plug-in space 132. The aforementioned front opening 130 and plug-in space 132 can communicate with the corresponding terminal slot 111. In other words, when the connector body 1 of this application requires a structure with multiple front openings 130 and plug-in spaces 132, the plug-in portion 13 can be a single block or multiple independent cylindrical sections. Furthermore, depending on the actual needs of the product, in some embodiments, when the base 11 is provided with only a single terminal slot 111, the plug-in portion 13 can be provided with only a single front opening 130 and a single plug-in portion space 132 to meet various application scenarios.
[0034] Furthermore, please refer to Figures 1 to 6 As shown, the metal terminal 2 can be connected to an electronic wire, and when the metal terminal 2 is installed to the connector body 1, it will be located in the corresponding terminal slot 111 and the insertion space 132. Specifically, a portion of the metal terminal 2 will be located in the insertion space 132, and the remaining portion of the metal terminal 2 will be located in the terminal slot 111. Furthermore, the metal terminal 2 includes at least one wing 21. In this embodiment, the metal terminal 2 has two wings 21 near the rear side. The plurality of wings 21 are elastic, and their ends are separated from each other in opposite directions. The maximum separation distance G is greater than the transverse width of the narrow slot region 111A of the terminal slot 111. When the metal terminal 2 is installed into the connector body 1, the plurality of wings 21 will be located in the terminal slot 111, and the ends of the plurality of wings 21 will be pressed into the narrow slot region 111A and abut against the inner wall of the corresponding narrow slot region 111A. At the same time, the plurality of wings 21 will each apply an unfolding force to the inner wall of the narrow slot region 111A. The aforementioned unfolding force helps the plurality of wings 21 return to their original shape (e.g., Figure 2 (as shown), however, in other embodiments of this application, the metal terminal 2 may not have a wing 21, or may have only a single wing 21.
[0035] In conclusion, please refer to the following: Figures 1 to 6As shown, by varying the width of the terminal slot 111, the narrow slot region 111A can fit tightly with a portion of the metal terminal 2 (e.g., the wing 21, or other parts of the metal terminal 2) to provide stronger mechanical fixing force, preventing the metal terminal 2 from shaking or shifting within the terminal slot 111. Simultaneously, when the plug connector C is inserted into the socket connector, the narrow slot region 111A ensures stable contact between the metal terminal 2 and the terminals of the socket connector, avoiding electrical faults caused by poor contact. Furthermore, the wide slot region 111C provides greater installation space, making it easier for the metal terminal 2 to extend into the terminal slot 111 when installed into the connector body 1.
[0036] In addition, to improve the stability of the metal terminal 2 when it is installed in the connector body 1, please refer to [further details]. Figure 1 and Figure 5 As shown, the metal terminal 2 is provided with at least one insert 23, which bends outward, meaning the bending direction of the insert 23 is away from the metal terminal 2 itself. Furthermore, at least one groove wall of the terminal slot 111 is provided with an insert recess 1110. In this embodiment, the insert recess 1110 is located on the groove wall of the corresponding narrow groove region 111A of the terminal slot 111 (such as the second vertical segment 1112). When the metal terminal 2 is installed into the terminal slot 111, the insert 23 can extend into the corresponding insert recess 1110. Thus, when the connector C is subjected to external forces (such as vibration) during use, it can still be stably positioned in the terminal slot 111 by means of the aforementioned design of the insert 23 and the insert recess 1110. Additionally, depending on the production requirements of the product, in this embodiment, the insert recess 1110 can penetrate the opposing groove walls of two adjacent terminal slots 111, but this is not a limitation.
[0037] The above description is merely a preferred and feasible embodiment of this application and does not limit the scope of protection of the claims of this application. Therefore, any equivalent changes that can be conceived by those skilled in the art based on the technical content disclosed in this application without creative effort should be included within the scope of protection of the claims of this application.
