[0033] Example 1:

[0034] Please see Figure 1-15 As shown, this utility model relates to a grounding component 4, which includes a grounding plate 41. The grounding plate 41 includes a contact surface 42 and a mounting surface 43. A grounding fixing part 431 is provided on the mounting surface 43, and the grounding fixing part 431 is used for mounting on an insulating component. In this utility model, the grounding component 4 is processed by a punching process, so that the grounding plate 41 is punched out with several pairs of grounding elastic parts 421. Each pair of grounding elastic parts 421 includes a first elastic arm 4213 and a second elastic arm 4214 symmetrically arranged, and the grounding elastic part 421 protrudes from the contact surface 42. The first elastic arm 4213 and the second elastic arm 4214 are symmetrically arranged along the length direction of the grounding plate 41 and respectively abut against both sides of the grounding terminal.

[0035] In this embodiment, each pair of grounding elastic portions 421 corresponds to the grounding terminal of the terminal group. In this first embodiment, adjacent grounding elastic portions 421 along the length of the grounding plate 41 are staggered vertically. The grounding plate 41 is punched to form a first punched hole 4211 and a second punched hole 4212, which are symmetrically arranged side-by-side along the length of the grounding plate 41. The first punched hole 4211 has an upwardly bent first elastic arm 4213 along its edge, located near the second punched hole 4212. The second punched hole 4212 has an upwardly bent second elastic arm 4214 along its edge, located near the first punched hole 4211. Therefore, in this first embodiment, the clamping distance between the first elastic arm 4213 and the second elastic arm 4214 is relatively small.

[0036] Furthermore, the first elastic arm 4213 is provided with a first grounding contact 4215, and the second elastic arm 4214 is provided with a second grounding contact 4216. The first grounding contact 4215 bends and protrudes toward the second elastic arm 4214, and the second grounding contact 4216 bends and protrudes toward the first elastic arm 4213, forming a grounding clamp 4217 between them. The grounding clamp 4217 is clamped on both sides of the grounding terminal, thereby achieving a better electrical connection.

[0037] This utility model also relates to an electrical connector, which includes an insulating component 1, a first terminal group 2, a second terminal group 3, and a grounding component 4. The insulating component 1 includes a front end face 11, a rear end face 13, and an insertion groove 14 for inserting a mating component (not shown in the figure). The insertion groove 14 passes through the front end face 11 and the rear end face 13. The front end face 11 is provided with a plurality of first terminal slots 12. The first terminal group 2 is inserted into the first terminal slots 12 from the front end face 11. The rear end face 13 is provided with a plurality of second terminal slots 15 and a grounding mounting groove 16. The grounding fixing part 431 is installed in the grounding mounting groove 16. After the second terminal group 3 is inserted into the second terminal slot 15, the grounding terminal of the second terminal group 3 is electrically connected to the grounding component 4.

[0038] In this embodiment, the second terminal group 3 is composed of several second terminals 31 arranged side by side. The second terminal 31 can be divided into signal terminals and ground terminals. In this embodiment, the signal terminals and ground terminals have basically the same shape, and the signal terminals and ground terminals can be distributed according to functional needs.

[0039] The second terminal 31 includes a second elastic portion 311, a second connecting portion 312, a second pin portion 313, and a second fixing portion 314. In this embodiment, the first grounding contact 4215 and the second grounding contact 4216 are clamped to the second connecting portion 312 of the grounding terminal. One end of the second connecting portion 312 is provided with the second elastic portion 311. In this embodiment, the second elastic portion 311 is vertically disposed on the second connecting portion 312. The end of the second elastic portion 311 has a second contact portion 3111, which protrudes downward from the second elastic member. The second contact portion 3111 is used to contact the upper part of the mating member and form an electrical connection. The other end of the second connecting portion 312 is provided with a second contact portion 313. In this embodiment, the second contact portion 313 is arranged in the opposite direction to the second elastic portion 311. The second contact portion 313 is vertically arranged on the second connecting portion 312 and is exposed at the bottom of the insulating member 1. It is used to contact the circuit board and form an electrical connection. In addition, in this embodiment, a second fixing portion 314 is provided at the middle position of the second connecting portion 312. The second fixing portion 314 is arranged in the same direction as the second elastic portion 311 and is vertically arranged on the second connecting member. The second fixing portion 314 is fixedly connected to the insulating member 1, so that the second terminal 31 is fixed on the insulating member 1.

[0040] Example 2:

[0041] The difference between this embodiment and embodiment one is that in this embodiment two, the grounding component 4 includes a grounding plate 41, which includes a contact surface 42 and a mounting surface 43. A grounding fixing part 431 is provided on the mounting surface 43, and the grounding fixing part 431 is used for mounting on an insulating component. In this utility model, the grounding component 4 is processed by a punching process, so that the grounding plate 41 is punched out with several pairs of grounding elastic parts 421, which protrude from the contact surface 42. The first elastic arm 4213 and the second elastic arm 4214 of the grounding elastic part 421 are arranged in a row along the width direction of the grounding plate 41 and abut against the same side of the grounding terminal.

[0042] In this embodiment, each pair of grounding elastic parts 421 corresponds to the grounding terminal of the terminal group. In this second embodiment, the grounding plate 41 is punched to form a first punched hole 4211 and a second punched hole 4212, which are arranged side by side along the height of the grounding plate 41. In this second embodiment, in order to improve the area utilization of the grounding plate 41, a processing position for punching another pair of grounding elastic parts 421 is reserved between the first punched hole 4211 and the second punched hole 4212. After punching, the two pairs of grounding elastic parts 421 are arranged alternately on the grounding plate 41, and the two pairs of grounding elastic parts 421 are respectively connected to different grounding terminals.

[0043] In this second embodiment, the first punching hole 4211 has an upwardly bent first elastic arm 4213 along its edge, and the second punching hole 4212 has an upwardly bent second elastic arm 4214 along its edge. The first elastic arm 4213 and the second elastic arm 4214 are located in the same column, and the first elastic arm 4213 and the second elastic arm 4214 are respectively connected to the same side of the grounding terminal.

[0044] The first elastic arm 4213 is provided with a first grounding contact 4215, and the second elastic arm 4214 is provided with a second grounding contact 4216. The first grounding contact 4215 and the second grounding contact 4216 are bent and protruded towards the grounding terminal, respectively. The first grounding contact 4215 and the second grounding contact 4216 protrude from the first elastic arm 4213 and the second elastic arm 4214 and connect to the grounding terminal, so that the grounding terminal has two contact points on the same side. Figure 9 .

[0045] This utility model relates to a grounding component and an electrical connector. By performing a punching process on the grounding component 4, several pairs of required grounding elastic parts 421 are directly formed on the grounding component 4. This process directly forms the grounding elastic parts 421 on the sheet metal, while also ensuring that the size and shape accuracy of the grounding elastic parts 421 are consistent. This fully utilizes raw material resources, reduces waste, and effectively saves manufacturing costs.
