Description

Technical Field

[0001] The utility model relates to the technology in the field of connectors, in particular to a female connector with a side-folded material strip and an electronic product, which mainly refers to a DP2.1 connector. Background Art

[0002] DisplayPort, also known as the High Definition Digital Display Interface, is a digital video interface standard promoted by the Video Electronics Standards Association. As one of the mainstream audio and video transmission interfaces, it is mainly used to connect computers and monitors, or computers and home theater systems.

[0003] The traditional DisplayPort electrical connector includes a shell, an insulating body, an upper row of terminals and a lower row of terminals, wherein the upper row of terminals and the lower row of terminals are injection molded into the insulating body at one time, and then the shell is wrapped around the outside of the insulating body. When the upper row of terminals and the lower row of terminals are injection molded into the insulating body at one time, the pre-breakage of the terminals is located at the front end of the tongue of the insulating body, and the distance between the front and rear ends of the tongue is large. After the DP connector male and the DP connector female are matched, the DP connector female terminal will form an open branch area of ​​a certain length, and the high-frequency signal will resonate back and forth in this open branch area. This resonance will greatly affect the loss and crosstalk of the high-frequency signal.

[0004] The front end pre-break of the differential pair terminal is designed to be retracted to shorten the open branch area, thereby improving the loss and crosstalk of high-frequency signals. However, the groove set at the front end pre-break is located just in front of the contact part of the terminal. When the DP connector male head is inserted, there is a problem that the male head spring terminal is stuck in the groove, causing the insertion to be blocked. Utility Model Content

[0011] The front ends of the first differential pair terminals, the second differential pair terminals, the third differential pair terminals, and the fourth differential pair terminals are all located behind the front end of the tongue plate to maintain a front-to-back spacing; the bottom of the tongue plate is provided with the groove corresponding to the front ends of the first differential pair terminals and the third differential pair terminals, which is defined as the first groove; the front end pre-broken parts of the first differential pair terminals and the third differential pair terminals are located in the groove; the top of the tongue plate is provided with the groove corresponding to the front ends of the second differential pair terminals and the fourth differential pair terminals, and the front end pre-broken parts of the second differential pair terminals and the fourth differential pair terminals are located in the groove, which is defined as the second groove.

Since the grooves are not directly in front of the same side of the differential pair terminal, the requirements for breaking the material strip are reduced during production, which is conducive to improving the process yield and reducing production costs.

[0029] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying 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 direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0030] A female connector, mainly refers to a high-frequency connector such as a DP2.1 female connector, which includes a terminal group 10, an insulating seat 20 injection-molded on the terminal group 10, and a metal shell 30 covering the outside of the insulating seat 20, and a rubber plug 40 is also provided at the bottom of the insulating seat 20. The insulating seat 20 has a tongue plate extending forward, and the metal shell 30 forms an insertion interface around the periphery of the tongue plate; the terminal group 10 extends forward to the upper and lower sides of the tongue plate.

[0031] Specifically, for the DP2.1 female connector, its terminal group 10 includes an upper row of terminals 1 and an upper row of terminals 2. Specifically, the upper row of terminals are from left to right: a first differential pair terminal 101 (referring to DIFF1), a second grounding terminal 102, a third differential pair terminal 103 (referring to DIFF5), a fourth grounding terminal 104, a CONFIG terminal, an I / O terminal, an I / O terminal, and a RIN terminal; the lower row of terminals are from left to right: a first grounding terminal 105, a second differential pair terminal 106 (referring to DIFF3), a third grounding terminal 107, a fourth differential pair terminal 108 (referring to DIFF7), a CONFIG terminal, a fifth grounding terminal, an In terminal, and a PWR Out terminal; usually, the terminal definition is based on the association specifications, and some terminals may be added or reduced as needed.

[0032] All the terminals of the upper row of terminals and the lower row of terminals include a contact portion 13, a fixing portion 14 and a welding portion 15 connected in sequence from front to back; the contact portion is an overall front-to-back horizontally extending structure, and the contact portion is exposed on one side surface of the tongue plate, that is, the contact portion of the upper row of terminals is exposed on the upper side surface of the tongue plate, and the contact portion of the lower row of terminals is exposed on the lower side surface of the tongue plate. The fixing portion is an L-shaped structure, which has a longitudinal portion extending horizontally front and back and a vertical portion extending vertically, the front end of the longitudinal portion is integrally connected to the rear end of the contact portion, the upper end of the vertical portion is integrally connected to the rear end of the longitudinal portion, and the welding portion is connected to the lower end of the vertical portion, and the welding portions of the upper row of terminals and the lower row of terminals are located in the same plane. During production, the upper row of terminals and the lower row of terminals are injection molded at one time, so that the terminal group 10 is fixed in the insulating seat 20, the contact portions of the upper row of terminals and the lower row of terminals are exposed on the upper and lower sides of the tongue plate respectively, and the welding portions are exposed at the tail end of the insulating seat 20.

[0033] The front end of the differential pair terminal is located behind the front end of the tongue plate to maintain the front-to-back spacing. The other pair of side surfaces of the tongue plate are provided with grooves toward the one side surface, and the front end pre-broken portion of the differential pair terminal is located in the groove. A support plane is reserved on one side surface of the tongue plate just in front of the contact portion for contact support when the male spring piece is inserted. A buried section is extended from the front end of the contact portion toward the inside of the tongue plate, and the front end of the buried section extends from the inner rear end surface of the groove, or the front end of the buried section is exposed from the inner rear end surface of the groove. In this embodiment, the front ends of the first differential pair terminals 101, the second differential pair terminals 106, the third differential pair terminals 103, and the fourth differential pair terminals 108 are all located behind the front end of the tongue plate to maintain a front-to-back spacing; and, a first groove 17 is provided at the bottom of the tongue plate corresponding to the front ends of the first differential pair terminals 101 and the third differential pair terminals 103, and the front end pre-broken parts of the first differential pair terminals 101 and the third differential pair terminals 103 are located in the first groove 17; a second groove 18 is provided at the top of the tongue plate corresponding to the front ends of the second differential pair terminals 106 and the fourth differential pair terminals 108, and the front end pre-broken parts of the second differential pair terminals 106 and the fourth differential pair terminals 108 are located in the second groove 18. That is, the left and right sides of the head ends of the first grounding terminal 105 and the third grounding terminal 107 are respectively provided with first grooves 17, and the left and right sides of the head ends of the second grounding terminal 102 and the fourth grounding terminal 104 are respectively provided with second grooves 18. The first differential pair terminal 101, the second differential pair terminal 106, the third differential pair terminal 103, and the fourth differential pair terminal 108 are all cut and cut on the opposite sides. Here, by shrinking the front end pre-break of the differential pair terminal to shorten the open branch area, the loss and crosstalk problems of high-frequency signals are greatly improved. Moreover, compared with the design scheme of setting the front pre-break groove in front of the same side of the differential terminal in the traditional technology, the grooves staggered up and down are adopted, so that the front side of the contact part of the differential pair terminal on the tongue plate is a plane. These grooves avoid contact with the spring terminal of the DP male connector, eliminating the risk of the spring terminal of the DP male connector being stuck when the grooves are on the same side (or the same row) in the traditional technology.

[0034] In addition, the front end heads of the same differential pair terminals are arranged close together, and the adjacent terminal heads of adjacent differential pair terminals are arranged away from (or far away from) each other to increase the distance between the adjacent terminal heads of adjacent differential pair terminals, reduce the mutual influence of the terminal heads as resonant transmitters and receivers, and thus reduce crosstalk; the right lower edge of the right terminal of the first differential pair terminal, the left upper edge of the left terminal of the second differential pair terminal, the right upper edge of the right terminal of the second differential pair terminal, the left lower edge of the left terminal of the third differential pair terminal, the right lower edge of the right terminal of the third differential pair terminal, and the left upper edge of the left terminal of the fourth differential pair terminal are all chamfered to form a chamfered slope 16 or a chamfered arc surface to reduce the distribution of electromagnetic field lines on adjacent differential pair terminals, thereby reducing crosstalk.

[0035] The first grounding terminal 105, the second grounding terminal 102, the third grounding terminal 107 and the fourth grounding terminal 104 all have two first isolation parts 11 that are widened laterally to the left and right. The first isolation part 11 is bent from the rear end of the contact part of the grounding terminal toward the fixed part of the corresponding differential pair terminal on the opposite side. The height of the first isolation part 11 is located between the upper row of differential pair terminals and the lower row of differential pair terminals. The outermost left and right widths of the two first isolation parts 11 are greater than the outermost left and right widths of the fixed parts of the corresponding differential pair terminals, so as to isolate the upper row of differential pair terminals and the lower row of differential pair terminals, reduce the crosstalk between the upper row of differential pair terminals and the lower row of differential pair terminals, especially the crosstalk between the upper and lower rows of adjacent differential pair terminals; the first isolation part The projection area of ​​the first isolation part 11 in the up-down direction covers the projection area of ​​the corresponding differential pair terminal in the up-down direction, and the outermost left-right width of the second isolation part 12 is greater than the outermost left-right width of the corresponding differential pair terminal, that is, the outermost left-right width of the first isolation part 11 of the first grounding terminal 105 is greater than the outermost left-right width of the first differential pair terminal 101, the outermost left-right width of the first isolation part 11 of the second grounding terminal 102 is greater than the outermost left-right width of the second differential pair terminal 106, the outermost left-right width of the first isolation part 11 of the third grounding terminal 107 is greater than the outermost left-right width of the third differential pair terminal 103, and the outermost left-right width of the first isolation part 11 of the fourth grounding terminal 104 is greater than the outermost left-right width of the fourth differential pair terminal 108. And the projection areas of the first isolation parts 11 of the first grounding terminal 105, the second grounding terminal 102, the third grounding terminal 107 and the fourth grounding terminal 104 are adjacently stacked (referring to the projection area in the up-down direction), effectively reducing the crosstalk between the upper row of differential pair terminals and the lower row of differential pair terminals.

[0036] At least the second grounding terminal 102 and the third grounding terminal 107 also have a second isolation portion 12 to isolate the upper row of differential pair terminals and adjacent differential pair terminals in the same row of the upper row of differential pair terminals; that is, the second isolation portion 12 of the second grounding terminal 102 is located between the first differential pair terminal 101 and the third branch pair terminal, and the second isolation portion 12 of the third grounding terminal 107 is located between the second differential pair terminal 106 and the fourth branch pair terminal, so as to reduce crosstalk between adjacent differential pair terminals in the same row. The second isolation portion 12 of the second grounding terminal 102 is arranged flush with the first differential pair terminal 101 and the third branch pair terminal in the left-right direction, and the second isolation portion 12 of the third grounding terminal 107 is arranged flush with the second differential pair terminal 106 and the fourth branch pair terminal in the left-right direction. The first grounding terminal 105, the second grounding terminal 102, the third grounding terminal 107, the fourth grounding terminal 104, the first differential pair terminal 101, the second differential pair terminal 106, the third differential pair terminal 103, and the fourth differential pair terminal 108 all include a contact portion, a fixing portion, and a welding portion that are sequentially connected from front to back; the first isolation portion 11 is bent from the rear end of the contact portion of the terminal toward the corresponding upper row terminal or the lower row terminal on the opposite side, that is: the first isolation portion 11 of the second grounding terminal 102 and the fourth grounding terminal 104 is bent toward the lower row terminal, and the first isolation portion 11 of the first grounding terminal 105 and the third grounding terminal 107 is bent toward the upper row terminal, which is equivalent to the first isolation portion 11 having deviated from the height of the contact portion of the terminal where it is located, and is approaching the area between the upper row differential pair terminal and the lower row differential pair terminal. The contact parts of the upper row are all located at a set height, and the contact parts of the lower row are all located at another set height; the second isolation part 12 of the second grounding terminal 102 is flush with the fixed parts of the first differential pair terminal 101 and the third differential pair terminal 103 in the left-right direction, and the second isolation part 12 of the third grounding terminal 107 is flush with the fixed parts of the second differential pair terminal 106 and the fourth differential pair terminal 108 in the left-right direction, so that the differential pairs in the same row are well isolated. The first isolation part 11 is flush with the fixed parts of the corresponding first differential pair terminal 101, the second differential pair terminal, the third differential pair terminal 103, and the fourth differential pair terminal 108 in the up-down direction.In the present embodiment, the first isolation portion 11 and the second isolation portion 12 of the first grounding terminal 105, the second grounding terminal 102, the third grounding terminal 107 and the fourth grounding terminal 104 adopt a structure divided into two in the longitudinal portion and the vertical portion. Therefore, "upper and lower row isolation" and "isolation of adjacent differential pair terminals in the same row" are formed with the corresponding differential pair terminals in the longitudinal portion and the vertical portion.

[0037] In this embodiment, the second isolation parts 12 of the second grounding terminal 102 and the third grounding terminal 107 are respectively located on the left and right sides of the first isolation parts 11 and form left and right side gaps, which are usually formed by punching or puncturing. The front and rear ends of the first isolation part 11 and the corresponding second isolation parts 12 on the left and right sides are respectively connected to the rear end of the contact part and the front end of the welding part. In actual production, the first grounding terminal 105, the second grounding terminal 102, the third grounding terminal 107 and the fourth grounding terminal 104 are designed to have the same structure for easy production. Figure 8 As shown, it can be seen that for the second grounding terminal 102 and the fourth grounding terminal 104 in the upper row, the height of the first isolation part 11 is lower than the height of the second isolation part 12, and for the first grounding terminal 105 and the third grounding terminal 107 in the lower row, the height of the first isolation part 11 is higher than the height of the second isolation part 12; the left and right outermost sides of the first isolation part 11 both exceed the left and right outermost sides of the corresponding differential pair terminals. Although there is a height difference between the first isolation part 11 in the upper row and the first isolation part 11 in the lower row, the projection areas of the first isolation parts 11 of the first grounding terminal 105, the second grounding terminal 102, the third grounding terminal 107 and the fourth grounding terminal 104 are adjacently stacked (referring to the projection area in the up and down direction), and the first isolation part 11 can be used to achieve the effect of a whole-piece middle separator. In addition, a positioning groove 111 is provided on the first isolation part 11, and the positioning groove 111 passes through the upper and lower ends of the first isolation part 11. By cleverly designing the structure of the grounding terminal, the terminal structure has better strength and improved deformation resistance, which is beneficial to the positioning and position retention of the entire terminal group 10 during injection molding, and the combination of the terminal group 10 and the insulating seat 20 is more stable.

[0038] Also, an electronic product is provided, which is provided with or connected with a female connector, and the female connector is the female connector of the side folded material strip as described in any of the above items.

[0039] The design focus of the utility model is that it mainly reduces the front end pre-break of the differential pair terminal by designing it to be inward to shorten the open branch area, greatly improving the loss and crosstalk problems of high-frequency signals, and adopts grooves that are staggered up and down, and folds the strip on the opposite side. These grooves avoid contact with the spring terminal of the male connector, eliminating the risk of the spring terminal of the male connector being stuck when the grooves are on the same side (or the same row). Since the grooves are not directly in front of the same side of the differential pair terminal, the requirements for the breaking process of the strip are reduced during production, which is conducive to improving the process yield and reducing production costs.

[0040] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
