Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of connector, concretely relates to a high density communication storage connector. BACKGROUND

[0002] Chinese patent CN202210624516.8 discloses an electric connector, which is a PCIE6.0 connector used for inserting electronic cards such as PCIE cards to transmit high-speed signals. The electric connector includes an insulating body, a plurality of terminals and a plug. The insulating body is provided with a mating surface, a slot formed by recessing from the mating surface, a slot bottom surface facing the mating surface, and two inner wall surfaces connecting the mating surface and the slot bottom surface. The top surface of the insulating body constitutes the mating surface, and the electronic card is inserted into the slot through the mating 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 grooves for accommodating corresponding terminals, the terminal grooves penetrate downward, inwardly penetrate the inner wall surface, and upwardly penetrate the mating surface.

[0003] The terminal includes a fixed part, an elastic arm and a pin part.

[0004] The plug is of an integrated structure and is installed on the insulating body. The plug includes an insulating insertion part inserted into the signal terminal groove and a conductive insertion part inserted into the ground terminal groove. The plug includes a bottom plate including a conductive plate layer and an insulating plate layer connected to each other. The insulating plate layer is wrapped on the upper and lower surfaces of the conductive plate layer. The conductive insertion part is formed by extending upwardly from the conductive plate layer. The insulating insertion part is formed by extending upwardly from the insulating plate layer. The conductive insertion part is made of conductive plastic material. The conductive plate layer and the conductive insertion part are formed by first injection molding. The insulating plate layer and the insulating insertion part are formed on the upper and lower surfaces of the conductive plate layer by second injection molding, thereby forming the plug of an integrated structure. The conductive insertion part and the insulating insertion part are both columnar insertion parts. Each of the two sides of the bottom plate is provided with a row of columnar insertion parts. Each row of columnar insertion parts extends in the longitudinal direction. The columnar insertion part abuts against the holding part of the terminal in the upper half close to the slot bottom surface, and is spaced apart from the terminal in the lower half away from the slot bottom surface. The interference between the columnar insertion part and the insulating body increases the holding force of the plug and the insulating body.

[0005] The above-mentioned electric connector is provided with a row of terminals on each of the two side walls of the slot. The number of terminals cannot be increased, so the signal transmission channel cannot be increased, and the signal transmission speed cannot be greatly improved. The plug uses the interference between the columnar insertion part and the insulating body to increase the holding force of the plug and the insulating body. This fixing method only uses the interference between the plastic and the plastic, which has the problem of insufficient holding force. In addition, the terminal and the plug are of a split type and are installed in the insulating body by insertion. During assembly, the terminal and the plug need to be inserted separately, which has a high probability of assembly error. Therefore, it needs to be improved. UTILITY MODEL CONTENTS

[0038] As shown in Figures 1-13 , the high-density communication storage connector comprises an insulating body 1, a plurality of terminals 2 and a plurality of plugs 3 accommodated in the insulating body 1.

[0039] The middle part of the top surface of the insulating body 1 is recessed along the longitudinal direction to form a longitudinal slot 11. The two sides of the slot 11 are provided with longitudinal side walls 12 arranged along the length direction of the slot 11. The two ends of the insulating body 1 in the length direction are provided with towers 13, and the two ends of the slot 11 in the length direction pass through the corresponding towers 13. The longitudinal side walls 12 on both sides of the slot 11 are provided with a plurality of terminal grooves 14. The size and structure of each terminal groove 14 are consistent, so that the terminal groove insert of the plastic mold used to form the insulating body 1 is single, and the error probability of assembling the mold is reduced. The terminal groove 14 penetrates the top surface and the bottom surface of the insulating body 1, and the terminal groove 14 also penetrates the slot surface of the longitudinal side wall 12. The slot 11 is provided with a foolproof part 15 connecting the two longitudinal side walls 12. The foolproof part 15 divides the slot 11 into a slot one and a slot two shorter than the slot one. The foolproof part 15 is used to prevent the electronic module 6 from being inserted reversely. The bottom surface of the insulating body 1 is protruded to form a heat melting structure 16 arranged along the longitudinal direction of the insulating body 1. The heat melting structure 16 has two parallel structures, and the two heat melting structures 16 are arranged at the positions corresponding to the bottom surface of the insulating body 1 and the slot 11. The two heat melting structures 16 are disconnected at the positions corresponding to the bottom surface of the insulating body 1 and the foolproof part 15 in the slot 11. That is, the positions corresponding to the bottom surface of the insulating body 1 and the foolproof part 15 are the cutting positions of the two heat melting structures 16. Between one side of the cutting position and the bottom surface of the tower at one end of the insulating body 1 is the two heat melting structures 16, and between the other side of the cutting position and the bottom surface of the tower at the other end of the insulating body 1 is also the two heat melting structures 16. Each heat melting structure 16 partially covers the bottom of the corresponding terminal groove 14 on the bottom surface of the insulating body 1, that is, the heat melting structure 16 partially overlaps the corresponding terminal groove 14 on the bottom surface of the insulating body 1, that is, the heat melting structure 16 extends below the bottom of the terminal groove 14 (as shown in Figure 11 , so as to facilitate the hot melting fixation of the plug 3.

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, so as to fix the electronic module 6. The metal lock structure 5 has a spring anti-retraction structure 51.

Each of the upper-layer terminals and the lower-layer terminals includes a fixed portion 21, the fixed portion 21 extends upward to form an arm portion 22, the end of the arm portion 22 protrudes to form a contact portion 23 toward the slot 11 side, and the lower end of the fixed portion 21 is connected to a welding portion 24.

The plug 3 embedded and formed together with the two terminals 2 and the plug 3 embedded and formed together with the one terminal 2 have the same structure and size, and the structure and size of the terminal groove 14 accommodating the plugs 3 are also the same, so that the manufacturing is more convenient and the assembly is simpler and faster.

[0044] The beneficial effects of the utility model mainly reflect in: through setting the hot melt structure 16 on the bottom of the insulating body 1, the bottom of each plug 3 is fixed by hot melt through the hot melt structure 16, so that the plug 3 and the insulating body 1 are more firmly fixed with each other, and the hot melt mode is more cost-saving, and has no signal interference to the terminal 2; through embedding the terminal 2 and the plug 3 in the mode of forming together, only the plug 3 is fixed in the terminal groove 14 in the mode of inserting and fixing, so that the assembly error rate can be reduced; through setting the double layer terminal in part of the terminal groove 14, the number of terminals is increased on the basis of the same structure space, so that the signal transmission channel is increased, and the signal transmission speed is greatly improved.
