DETAILED DESCRIPTION

[0026] 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.

[0027] like Figure 1-15 As shown, the high-speed and high-density combined storage connector includes an insulating body 1, a plurality of terminals 2 accommodated in the insulating body 1, two ear buckles 4 and two metal locking structures 5.

[0028] The middle part of the top surface of the insulating body 1 is concave in the longitudinal direction to form two longitudinal slots 11. The centers of the two slots 11 of the insulating body 1 are on the same straight line, so that the insulating body 1 with two slots 11 only needs to be formed once, which can not only reduce the number of processing times, but also only needs to be clamped once to assemble the terminals 2 in the longitudinal side walls 12 on both sides of the two slots 11. Both sides of each slot 11 have longitudinal side walls 12 arranged along the length direction of the slot 11, and both ends and the middle part of the length direction of the insulating body 1 are provided with a tower portion 13. The longitudinal side walls 12 on both sides of each slot 11 are provided with a plurality of terminal slots 14. The terminal slots 14 penetrate the bottom surface of the insulating body 1, and the terminal slots 14 also penetrate the slot-facing surface of the longitudinal side walls 12. Each slot 11 is provided with an anti-mistake portion 15 connecting the two longitudinal side walls 12. The anti-mistake portion 15 divides the slot 11 into slot one and slot two whose length is shorter than slot one. The anti-mistake portion 15 is used to prevent the electronic module 6 from being reversely inserted. The two foolproofing parts 15 are both close to the middle tower part 13 and are symmetrically arranged with the center of the middle tower part 13 as the symmetry axis. Alternatively, the two foolproofing parts 15 are both away from the tower part 13 on the same side (the two foolproofing parts 15 are both away from the tower part 13 on the left or the tower part 13 on the right).

[0029] The towers 13 at both ends of the insulating body 1 have ear buckle accommodating spaces, and a pivoting portion pivotally connected to the ear buckle 4 is arranged in the ear buckle accommodating space, and the ear buckle 4 is located in the ear buckle accommodating space and pivotally connected to the pivoting portion. The tower 13 in the middle of the insulating body 1 is provided with two metal lock structures 5, and the metal lock structures 5 have a spring anti-retraction structure 51, so that the electronic module 6 inserted in each slot 11 is fixed in a single-side ear buckle manner with an ear buckle 4 on one side and a metal lock structure 5 on the other side, which can save the space occupied by opening the ear buckle.

[0030] The top surface of the middle tower portion 13 is concave in the middle to form a concave groove 131, which does not penetrate the bottom of the insulating body 1, and both sides of the concave groove 131 are connected to the two slots 11. An iron foot 7 is embedded and fixed in the center of the bottom surface of the middle tower portion 13, and an iron foot 7 is also embedded and fixed at the bottom of the ends of the two insulating bodies 1 that are away from each other. The iron foot 7 is used to connect with the circuit board to fix the insulating body 1 to the circuit board.

[0031] The multiple terminals 2 are respectively and one by one accommodated in the corresponding terminal slots 14 in the two longitudinal side walls 12 on both sides of each slot 11. Some of the terminals 2 in each longitudinal side wall 12 are set as double-layer terminals, that is, at least a part of the terminal slots 14 are set with double-layer terminals (it can be a terminal slot 14 on one or two or three or four longitudinal side walls 12 with double-layer terminals, or it can be a terminal slot 14 on one or two or three or four longitudinal side walls 12 with multiple spaced terminals), and the remaining terminal slots 14 are single-layer terminals. Specifically, in the length direction of each longitudinal side wall 12, it is divided into a plurality of spaced local areas, and in each local area there are a plurality of continuous terminal slots 14, each terminal slot 14 is set with a double-layer terminal, and single-layer terminals are arranged on both sides of the double-layer terminals in each local area. The spacing between each adjacent two local areas is not equal (the spacing between each adjacent two areas can also be completely equal or partially equal).

[0032] 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. The size and structure of each terminal groove 14 accommodating the lower row of terminals of the insulating body 1 are consistent, and the size and structure of each terminal groove 14 accommodating the upper row of terminals are consistent.

[0033] 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 top surface of the longitudinal side wall 12 is recessed downward at the position corresponding to the terminal groove 14 for accommodating each single-layer terminal to form a groove 16 that is not connected to the terminal groove 14 for accommodating the single-layer terminal. 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.

[0034] The length of the terminal groove 14 for accommodating each of the upper terminals on the top surface of the insulating body 1 along the width direction of the insulating body 1 is greater than the length of the terminal groove 14 on the bottom surface of the insulating body 1 along the width direction of the insulating body 1; the length of the terminal groove 14 for accommodating each of the upper terminals on the top surface of the insulating body 1 along the width direction of the insulating body 1 is greater than the length of the terminal groove 14 for accommodating each of the lower terminals on the bottom surface of the insulating body 1 along the width direction of the insulating body 1; the length of the terminal groove 14 for accommodating each of the upper terminals on the bottom surface of the insulating body 1 along the width direction of the insulating body 1 is less than the length of the terminal groove 14 for accommodating each of the lower terminals on the bottom surface of the insulating body 1 along the width direction of the insulating body 1.

[0035] 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.

[0036] 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 221 and a lower arm portion 222 respectively, and the lower end of the lower arm portion 222 is bent toward the inner side of the insulating body 1 to form a welding portion 24, and the upper end of the upper arm portion 221 of the lower terminal protrudes toward the slot 11 to form a contact portion 23 (the single-layer terminal has the same structure as the lower terminal, so its structure is not repeated), and the upper end of the upper arm portion 221 of the upper terminal extends toward the slot 11 to form an upper oblique arm 2a, and the end of the upper oblique arm 2a is bent downward to form a lower oblique contact arm 2b, and the end of the lower oblique contact arm 2b is a contact portion, and the contact portion extends into the slot 11.

[0037] The contact portion of the upper terminal is higher than the contact portion 23 of the lower terminal, the welding portion 24 of the upper terminal is flush with the welding portion 24 of the lower terminal, the welding portion 24 of the upper terminal and the welding portion 24 of the lower terminal are oriented in the same direction, the welding portion 24 of the single-layer terminal and the welding portion 24 of the lower terminal are oriented in the same direction and are both toward the inner side of the insulating body 1.

[0038] Compared with the prior art, the beneficial effects of the present invention are mainly reflected in: by arranging two slots 11 for inserting two electronic modules on an insulating body 1, the memory can be expanded without occupying the space of the circuit board; by making the centers of the two slots 11 on the same straight line, the insulating body 1 only needs to be formed once, which not only reduces the number of processing times, but also only requires one clamping to assemble the terminals 2 on both sides of the two slots 11 of the insulating body 1; by arranging double-layer terminals in at least a part of the terminal slots 11, a design of partial double-layer terminals is formed, and the number of terminals 2 is increased without changing the structural space of the longitudinal side walls 12 on both sides of each slot 11, thereby increasing the signal transmission channel and greatly improving the signal transmission speed; the upper terminal of the double-layer terminal is inserted and fixed in the terminal slot 14 from top to bottom, and the lower terminal is inserted and fixed in the terminal slot 14 from bottom to top, without the need for plugs and the step of plug assembly, which not only can realize high-speed automated plug production, but also reduce costs and improve the yield; by arranging iron feet 7, the connector as a whole is stably and firmly fixed on the circuit board.

[0039] In other embodiments, Figure 16-19 As shown above Figure 1-15 The difference is that the centers of the two slots 11 are not on the same straight line, so that when the electronic modules 6 are inserted into the two slots 11, the adjacent electronic modules 6 can be prevented from colliding with each other. The foolproof parts 15 of the two tower parts 13 near the middle are asymmetrical.

[0040] In other embodiments, Figure 20-29 As shown above Figure 1-15 The difference is that the terminal slots 14 of the insulating body 1 are of the same size but different in structure. Each terminal slot 14 passes through the top and bottom surfaces of the insulating body 1. The length of the terminal slot 14 on the bottom surface of the insulating body 1 along the width direction of the insulating body 1 is greater than the length of the terminal slot 14 on the top surface of the insulating body 1 along the width direction of the insulating body 1. Each terminal slot 14 also passes through the slot-facing surface of the longitudinal side wall 12. Each single-layer terminal is fixed in the corresponding terminal slot 14 by plugging. At the position of the double-layer terminal, the two terminals 2 in each terminal slot 14 are embedded and molded together with a plug 3, and the plug 3 is inserted and fixed in the terminal slot 14. The structures of the lower and upper terminals of the single-layer terminals and the double-layer terminals in the remaining terminal slots 14 are different. By embedding the double-layer terminal with the plug 3, only the plug 3 is fixed in the terminal slot 14 by plugging, which can reduce the assembly error rate. By fixing the single-layer terminal in the terminal slot 14 by plugging, the embedded molding process can be reduced, and the manufacturing cost can be reduced.

[0041] The structures of the lower terminal and the upper terminal of each single-layer terminal and double-layer terminal are different. Each of the upper terminal and the lower terminal includes a fixing portion 21, which extends upward to form an arm portion 22, the end of the arm portion 22 protrudes toward the slot 11 to form a contact portion 23, and the lower end of the fixing portion 21 is connected to a welding portion 24. The outer side of the fixing portion 21 of each upper terminal away from the slot 11 protrudes outward to form a buckling portion 25, and the buckling portion 25 is clamped and fixed on the inner wall of the terminal slot 14.

The second soldering portion 29 of the single-layer terminal and the first soldering portion 24 of the upper-layer terminal of the double-layer terminal are designed to face the outside of the insulating body 1, which is not only convenient for checking the soldering effect, but also more conducive to PCB routing.

[0043] The plug 3 includes a main board body 31, the top of the main board body 31 protrudes to form a protruding portion 32 on the side close to the slot 11 and the side away from the slot 11, and a notch 33 is formed between the two protruding portions 32. The main board body 31 and the two protruding portions 32 form a U-shaped structure. The protruding portion 32 on the side away from the slot 11 protrudes outward to form a retaining portion 34, and the retaining portion 34 is clamped and fixed on the inner wall of the terminal slot 14. Each fixing portion 1 21 is embedded and molded together with the main board body 31 of the plug 3, and each arm portion 1 22 extends out of the top of the plug 3.

The bottom surface of the main body 31 is substantially flush with the bottom surface of the insulating body 1 .

[0044] In other embodiments, Figure 30-32 As shown above Figure 20-29 The difference is that the sizes and structures of the terminal slots 14 of the insulating body 1 are consistent, so that the terminal slot inserts of the plastic mold used to form the insulating body 1 are single, and the error probability when assembling the mold is reduced.

[0045] Each single-layer terminal is flush with the lower-layer terminal to form a row. Each single-layer terminal has the same structure as the lower-layer terminal, and each single-layer terminal has a different structure from the upper-layer terminal. The structures of the upper-layer terminal and the lower-layer terminal are the same as above. Fig.26 The upper terminal and the lower terminal have the same structure. The diagram of the double-layer terminal combined with the insulating body 1 is the same as the above diagram. Fig.28 Same as shown, single-layer terminals are the same as above Fig.26 The lower terminal structure shown is the same. The welding portion 24 of the single-layer terminal and the welding portion 24 of the lower terminal of the double-layer terminal are oriented in the same direction (eg Fig.28 and Fig.32 as shown).

In the position of the double-layer terminal, there are two terminals 2 (i.e., a lower terminal and an upper terminal) in each terminal slot 14, and the two terminals 2 in each terminal slot 14 (i.e., a lower terminal and an upper terminal) are embedded and molded together with the plug 3 in the terminal slot 14; in the position of the single-layer terminal, there is only one terminal 2 in each terminal slot 14, and the one terminal 2 in each terminal slot 14 is embedded and molded together with the plug 3 in the terminal slot 14. By embedding and molding the terminal 2 and the plug 3 together, only the plug 3 is held in the terminal slot 14 in an insertion and fixing manner, which can reduce the assembly error rate.

[0047] The plug 3 embedded with the two terminals 2 and the plug 3 embedded with one terminal 2 have the same structure and size, and the terminal slots 14 accommodating each plug 3 also have the same structure and size, making manufacturing more convenient and assembly simpler and faster.

The metal protective part 9 is embedded and fixed in the retaining grooves 1a of the two longitudinal side walls 12 toward the two sides of the two longitudinal side walls 12.

[0051] The metal protection part 1b includes two guard plates 1b1 located on the two side surfaces of the fool-proof part 15. Each guard plate 1b1 is embedded and fixed in the holding groove 1a of the two longitudinal side walls 12 toward the two sides of the two longitudinal side walls 12. The upper ends of the two guard plates 1b1 are connected by an arc plate 1b2 located above the fool-proof part 15. The lower end of one of the two guard plates 1b1 extends downward to form a welding foot 1b3 that passes through the bottom of the insulating body 1. Each guard plate 1b1 expands outward toward the upper part of the two sides of the two longitudinal side walls 12 to form a shoulder 1b4, and the shoulder 1b4 is located at the upper wide position of the step groove. The guard plate 1b1 with the welding foot 1b3 protrudes outward toward the two sides of the two longitudinal side walls 12 to form a clamping part 1b5, and the clamping part 1b5 is clamped at the lower narrow position of the step groove.
