Description

Technical Field

[0001] The invention belongs to the field of connectors, and in particular relates to a high-speed and high-density connector with shielding. Background Art

[0002] Chinese patent CN202210624516.8 discloses an electrical connector, which is a PCIE6.0 connector, used to plug in electronic cards such as PCIE cards and transmit high-speed signals. The electrical connector includes an insulating body, a plurality of terminals and a plug. The insulating body is provided with a docking surface, a slot formed by a recessed arrangement of the docking surface, and the slot is provided with a slot bottom surface facing the docking surface, and two inner wall surfaces connecting the docking surface and the slot bottom surface. The top surface of the insulating body constitutes the docking surface, and the electronic card is inserted into the slot through the docking surface. The insulating body includes two side walls located on both sides of the slot, each side wall is provided with a plurality of terminal slots, which accommodate corresponding terminals one by one, and the terminal slots penetrate downward, penetrate the inner wall surface inward, and penetrate the docking surface upward at the same time.

[0003] The terminal includes a fixing portion, an elastic arm and a pin portion.

[0004] The plug is an integrated structure and is installed on the insulating body. The plug includes an insulating insert inserted into the signal terminal slot and a conductive insert inserted into the ground terminal slot. The plug includes a bottom plate. The bottom plate includes a conductive plate layer and an insulating plate layer connected to each other as a whole. The insulating plate layer is wrapped around the upper and lower surfaces of the conductive plate layer. The conductive insert is formed by extending upward from the conductive plate layer as a whole. The insulating insert is formed by extending upward from the insulating plate layer as a whole. The conductive insert is a conductive plastic material. The conductive plate layer and the conductive insert are first formed by a first injection molding method. Then, the insulating plate layer and the insulating insert are formed on the upper and lower surfaces of the conductive plate layer by a second injection molding method, thereby forming an integrated plug. Both the conductive insert and the insulating insert are columnar inserts. A row of columnar inserts is provided on each lateral side of the bottom plate. Each row of columnar inserts extends in the longitudinal direction. The columnar inserting portion abuts against the retaining portion of the terminal at the upper half near the bottom of the slot, and is spaced a certain distance from the terminal at the lower half away from the bottom of the slot. The interference between the columnar inserting portion and the insulating body is utilized to increase the retaining force between the plug and the insulating body.

[0005] A row of terminals is respectively arranged on the two side walls on both sides of the slot of the above-mentioned electrical connector, and the number of terminals cannot be increased, so the signal transmission channel cannot be increased, and the signal transmission speed cannot be greatly improved; moreover, the terminals and plugs are split and are installed in the insulating body by plug-in method. They need to be plugged in separately during assembly, and the probability of assembly errors is high.

[0006] Chinese patent CN201711339370.8 discloses a card edge connector, comprising an insulating housing and a terminal module, wherein the terminal module comprises a terminal retaining seat and a plurality of conductive terminals fixed to the terminal retaining seat. The insulating housing comprises a plug-in surface and a mounting surface located on opposite sides, a card edge slot opening toward the plug-in surface for inserting the docking mark, and a terminal retaining seat mounting slot opening toward the mounting surface and connected to the card edge slot. The terminal module also comprises a common grounding shielding member, which is arranged between the terminal retaining seat and the side wall of the insulating housing. Although the card edge connector can enhance the grounding characteristics to produce a shielding effect between signal terminals through the common grounding shielding member, a row of terminals are respectively arranged on the two side walls on both sides of the card edge slot, and the number of terminals cannot be increased, so the signal transmission channel cannot be increased, and the signal transmission speed cannot be greatly improved.

DETAILED DESCRIPTION

[0022] In order to facilitate a better understanding of the purpose, structure, characteristics and effects of the present invention, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1-20 As shown, the shielded high-speed and high-density connector comprises an insulating body 1 , a plurality of terminals 2 received in the insulating body 1 , and a plurality of plugs 3 .

[0024] The middle part of the top surface of the insulating body 1 is concave in the longitudinal direction to form a longitudinal slot 11. The slot 11 has longitudinal side walls 12 arranged along the length direction of the slot 11 on both sides. Both ends of the insulating body 1 in the length direction are provided with a tower portion 13, and the two ends of the slot 11 pass through the corresponding tower portions 13. The longitudinal side walls 12 on both sides of the slot 11 are provided with a plurality of terminal slots 14. The terminal slots 14 pass through the bottom surface of the insulating body 1, and the terminal slots 14 also pass through the slot-facing surface of the longitudinal side walls 12. An anti-mute portion 15 connecting the two longitudinal side walls 12 is provided in the slot 11. The anti-mute portion 15 divides the slot 11 into slot one and slot two whose length is shorter than slot one. The anti-mute portion 15 is used to prevent the electronic module 6 from being reversely inserted.

[0025] One of the towers 13 of the insulating body 1 has an ear buckle accommodating space, and the tower 13 has a pivoting portion for pivoting the ear buckle and is provided with an ear buckle 4. The other tower 13 is provided with a metal lock structure 5, and the metal lock structure 5 has a spring anti-retraction structure 51. The single-sided ear buckle can save space occupied by opening the ear buckle. The ear buckle 4 and the metal lock structure 5 are buckled and fixed on both sides of the electronic module 6 inserted into the slot 11 to fix the electronic module 6. An iron foot 7 is fixed at the bottom of the two towers 13 of the insulating body 1, which is used to connect with the circuit board to fix the insulating body 1 to the circuit board.

[0026] The multiple terminals 2 are respectively and one by one accommodated in the corresponding terminal slots 14 in the two longitudinal side walls 12. Some of the terminals 2 in each of the longitudinal side walls 12 are partially set as double-layer terminals, that is, at least a part of the terminal slots 14 are set with double-layer terminals (double-layer terminals can be set in one terminal slot 14, or double-layer terminals can be set in multiple spaced terminal slots), and the remaining terminal slots 14 are single-layer terminals. Specifically, in the length direction of each of the longitudinal side walls, it is divided into at least two spaced areas, and there are multiple continuous terminal slots in each area. Double-layer terminals are set in each terminal slot, and single-layer terminals are arranged on both sides of the double-layer terminals in each area. A shielding member 8 is set in each area to separate the upper terminal and the lower terminal in the area, and the shielding member 8 in each area is independently set (in the case where a double-layer terminal is set in only one terminal slot 14 in one area, only one shielding member 8 is needed). The bottom sides of the independently arranged shielding member 8 are vertically bent with welding feet 81, which are located on the bottom surface of the insulating body 1. All upper terminals in each area are located between the welding feet 81 on both sides of the bottom of the shielding member 8 in the area. The shielding member 8 can be made of metal or conductive plastic.

[0027] The double-layer terminal includes a lower terminal and an upper terminal. The upper terminal of the double-layer terminal is inserted downward from the top of the insulating body 1 and fixed in the terminal groove 14. The lower terminal of the double-layer terminal is inserted upward from the bottom of the insulating body 1 and fixed in the terminal groove 14. The single-layer terminal is inserted upward from the bottom of the insulating body 1 and fixed in the terminal groove 14. Each single-layer terminal is flush with the lower terminal and forms a row. Each single-layer terminal has the same structure as the lower terminal, and each single-layer terminal has a different structure from the upper terminal. The terminal groove 14 accommodating each single-layer terminal has the same structure as the terminal groove 14 accommodating each lower terminal, and the terminal groove 14 accommodating each single-layer terminal has a different structure from the terminal groove 14 accommodating each upper terminal.

[0028] The terminal groove 14 for accommodating the single-layer terminal does not penetrate the top surface of the longitudinal side wall 12 of the insulating body 1.

The terminal groove 14 for accommodating the upper terminal penetrates the top surface of the longitudinal side wall of the insulating body 1. A partition wall 17 is provided between the terminal groove 14 for accommodating the lower terminal and the terminal groove 14 for accommodating the upper terminal to completely separate them. The partition wall 17 includes a vertical wall 171 and a horizontal wall 172. The vertical wall 171 extends downward to be flush with the bottom surface of the insulating body 1. The horizontal wall 172 extends toward the slot 11 to be flush with the slot-facing surface of the longitudinal side wall 12. The upper end of the vertical wall 171 is vertically connected to the end of the horizontal wall 172 away from the slot. The terminal grooves 14 for receiving the upper terminals are connected from the top surface of the longitudinal side wall of the insulating body 1 to the slot 11 to the slot-facing surface of the longitudinal side wall, so that an independent fence 19 is formed between each two adjacent terminal grooves 14 for receiving the upper terminals. The top surface of each independent fence 19 is lower than the top surface of the longitudinal side wall 12 of the insulating body 1, so that when the electronic module 6 is inserted into the slot 11, it first hits the top surface of the longitudinal side wall 12 of the insulating body 1, and does not hit the top surface of the independent fence 19 first, thereby protecting the upper terminals next to the independent fence 19. A rectangular groove 121 with an open inner side is formed on the top surface of the longitudinal side wall 12 corresponding to the terminal groove 14 for receiving the upper terminals. A plurality of independent fences 19 are located below the rectangular groove 121, and the outer sides of the plurality of independent fences 19 are connected to the side wall of the rectangular groove 121 close to the outer side of the insulating body.

[0031] The terminal grooves 14 for receiving the upper terminals are arranged in a row on the top surface of the longitudinal side wall 12 of the insulating body 1 and the grooves 16 concave on the top surface of the longitudinal side wall 12. The terminal grooves 14 for receiving the upper terminals and the terminal grooves 14 for receiving the lower terminals are arranged in a row on the bottom surface of the insulating body 1. On the bottom surface of the insulating body 1, the terminal grooves 14 for receiving the upper terminals are on the outside, and the terminal grooves 14 for receiving the lower terminals are on the inside. The terminal grooves 14 for receiving the upper terminals form a plurality of terminal groove groups arranged at intervals in the longitudinal direction of the insulating body 1. On the top surface of each longitudinal side wall 12 of the insulating body 1, a plurality of grooves 16 are arranged between each adjacent two terminal groove groups. The top surfaces of the two longitudinal side walls 12 are provided with a plurality of material cutting grooves 18 at both sides of the foolproof portion 15 along the length direction of the longitudinal side walls 12, and each longitudinal side wall 12 has a plurality of grooves 16 on both sides of the plurality of material cutting grooves 18 on the top surface. The provision of the material cutting groove 18 and the groove 16 can not only save materials and reduce the weight of the insulating body 1 , but also prevent the insulating body 1 from warping and facilitate mold forming.

[0032] The upper terminal and the lower terminal both include a fixing portion 21 fixed in the corresponding terminal slot 14, and an opening 211 is provided in the middle of the fixing portion 21 to save metal materials. The inner side of the fixing portion 21 protrudes with a clamping point 212 clamped on the inner wall of the corresponding terminal slot 14. The fixing portion 21 extends upward and downward to form an upper arm portion 22 and a lower arm portion 23 respectively, and the lower end of the lower arm portion 23 is bent toward the inner side of the insulating body 1 to form a welding portion 24. The upper end of the upper arm portion 22 of the lower terminal protrudes toward the slot 11 to form a contact portion 25, and the upper end of the upper arm portion 22 of the upper terminal extends toward the slot 11 to form an upper oblique arm 26, and the end of the upper oblique arm 26 is bent downward to form a lower oblique contact arm 27, and the end of the lower oblique contact arm 27 is a contact end, and the contact end extends into the slot 11.
