Specific implementation manners

[0029] Please refer to Figure 1 and Figure 2 as shown, which are a schematic perspective view and a schematic exploded perspective view of a preferred embodiment of the present utility model. The present utility model is a DisplayPort electrical connector, and the electrical connector 1 mainly includes a first terminal assembly 10, a second terminal assembly 11, a third colloid 12 and an iron shell 13.

[0030] Referring also to Figure 3 , Figure 4 and Figure 5As shown, it is a schematic structural diagram of the first molding of the first terminal assembly of the present utility model, a schematic structural diagram of the second molding of the second terminal assembly, and a schematic structural diagram of the third molding of the first terminal assembly and the second terminal assembly by the third colloid. The first terminal assembly 10 includes a plurality of first terminals 100 and a first colloid 102, and the first colloid 102 injects and forms each first terminal 102 in an integrally formed manner. Each first terminal 100 is respectively defined with a first contact section 1000, a first welding section 1002, and a first connection section 1004 located between the first contact section 1000 and the first welding section 1002. Each first terminal 100 is defined as a differential positive signal, a differential negative signal, a ground signal, a differential positive signal, a differential negative signal, a ground signal, an electrical variation signal (CONFIG), an audio differential positive signal, an audio differential negative signal, and a power signal in sequence from right to left.

[0031] The second terminal assembly 11 includes a plurality of second terminals 110 and a second colloid 112, and the second colloid 112 injects and forms each second terminal 110 in an integrally formed manner. Each second terminal 110 is respectively defined with a second contact section 1100, a second welding section 1102, and a second connection section 1104 located between the second contact section 1100 and the second welding section 1102. Each second terminal 110 is defined as a ground signal, a differential positive signal, a differential negative signal, a ground signal, a differential positive signal, a differential negative signal, an electrical variation signal (CONFIG), a ground signal, a hot plug detection signal, and a power signal in sequence from right to left.

[0032] After completing the first molding of the first terminal assembly 10 and the second molding of the second terminal assembly 11 as described above, a metal sheet 14 is disposed between the first terminal assembly 10 and the second terminal assembly 11. The positioning posts 1120 protruding from the second colloid 112 pass through the through holes 140 defined by the metal sheet 14 and the fixing holes 1020 defined on the first colloid 102, so that the metal sheet 14 is fixed between the first terminal assembly 10 and the second terminal assembly 11. At this time, each second terminal 110 and each first terminal 100 are arranged in an interleaved manner (refer to Figure 8 ).

[0033] When the first terminal assembly 10 and the second terminal assembly 11 are subjected to the third molding by the third colloid 12 to form a base 120 for each first welding section 1002 and each second welding section 1102 to protrude and a tongue plate 122 extending from the base 120, with the upper and lower surfaces of the tongue plate respectively exposing each first contact section 1000 and each second contact section 1102, and finally the first terminal assembly 10, the second terminal assembly 11, and the third colloid 12 that have completed three moldings are inserted into the accommodation space 130 of the iron shell 13.

[0034] In addition, a plurality of elastic members 132 are provided on the upper and lower surfaces of the iron shell 13. Both ends of each elastic member 132 are respectively connected to the iron shell, thereby improving the plugging and unplugging effect of each elastic member 132 after the contact connector plug is inserted. Furthermore, a plurality of fixing feet 134 for fixing to the circuit board extend downward from the iron shell 13. A convex bulge 136 is formed on one side of each fixing foot 134. After the fixing feet 134 are inserted into the fixing holes of the circuit board, the contact area with the fixing holes can be increased through the convex bulge 136, thereby improving the interference effect after insertion and avoiding possible detachment during welding due to loosening.

[0035] As can be seen from the above structure, the present utility model is formed by the first terminal assembly 10 completing the first molding, the second terminal assembly 11 completing the second molding, and the third colloid 12 integrally molding the first terminal assembly 10 and the second terminal assembly 11. The DisplayPort electrical connector is made by the above three molding methods, thereby being applicable to DisplayPort 2.1 and passing its high-frequency test and structural strength.

[0036] Refer to together Figure 6 、 Figure 7 and Figure 8 shown are a schematic structural diagram of adding a base to the present utility model, a side view structural diagram of the first terminal, the metal sheet and the second terminal, and a top view structural diagram of the first terminal and the second terminal. Figure 6 As can be seen from [relevant reference], when the positioning effect of the electrical connector 1 on the circuit board needs to be strengthened, a base 15 can be directly provided below the third colloid 12 in the electrical connector 1. Clamping members 150 extend from two corresponding sides of the base 15, and positioning posts 152 extend downward from the base 15. The clamping members 150 are clamped in the fixing grooves 1200 formed on both sides of the base 120. Then, when the electrical connector 1 is installed on the circuit board, positioning can be performed through the positioning posts 152, improving the efficiency when the electrical connector 1 is fixed on the circuit board.

[0037] On the other hand, as can be known from Figure 7 and Figure 8 in order to improve the effect of guiding noise, a contact portion 16 in contact with the metal sheet 14 is respectively provided for each first grounding terminal 100 and each second grounding terminal 110 facing the metal sheet 14. The contact portion 16 is mainly formed by bending the first grounding terminal 100 at the first connection section 1004 and bending the second grounding terminal 110 at the second connection section 1104, thereby increasing the contact path between the first grounding terminal 100 and each second grounding terminal 110 and the metal sheet 14, and further improving the effect of guiding noise of the connector 1.

[0038] Furthermore, the width of the first connection section 1004 of each first ground terminal 100 is greater than that of the first contact section 1000 and the first welding section 1002, and the width of the second connection section 1104 of each second ground terminal 110 is greater than that of the second contact section 1100 and the second welding section 1102. Thereby, the effect of noise elimination is better than that of the ground terminals with a narrow width.
