[0022] 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. A tower portion 13 (with an ear buckle accommodating space) is provided at both ends of the length direction of the insulating body 1. The tower portion 13 has a pivoting portion for pivoting the ear buckle. The two ends of the slot 11 pass through the corresponding tower portion 13. The longitudinal side walls 12 on both sides of the slot 11 are provided with a plurality of terminal slots 14. The size and structure of each terminal slot 14 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 is reduced when assembling the mold. The terminal slot 14 passes through the top and bottom surfaces of the insulating body 1, and the terminal slot 14 also passes through the slot-facing surface of the longitudinal side wall 12. The slot 11 is provided with a foolproof portion 15 connecting the two longitudinal side walls 12. The foolproof portion 15 divides the slot 11 into a slot 1 and a slot 2 whose length is shorter than the slot 1. The foolproof portion 15 is used to prevent the electronic module 6 from being reversely inserted.

[0023] Two buckle grooves 61 are provided on both sides of the length direction of the electronic module 6 (one buckle groove 61 may also be provided on both sides of the length direction of the electronic module 6, and the buckle grooves 61 on both sides are symmetrical or staggered). An ear buckle 4 is provided on one of the tower portions 13 of the insulating body 1, and an ear buckle 4 is also provided on the other tower portion 13. The two ear buckles 4 are buckled and fixed in the buckle grooves 61 on the upper parts of 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 tower portions 13 of the insulating body 1 for connecting with the circuit board to fix the insulating body 1 to the circuit board.

[0024] The multiple terminals 2 are respectively and one by one accommodated in the corresponding terminal grooves 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 one local area of ​​the terminal groove 14 is set with a double-layer terminal (it can be a double-layer terminal set in one terminal groove 14, or a double-layer terminal can be set in multiple spaced terminal grooves), and the remaining terminal grooves 14 are single-layer terminals. Specifically, in the length direction of each of the longitudinal side walls 12, it is divided into a plurality of spaced local areas, and there are a plurality of continuous terminal grooves 14 in each local area, and each terminal groove 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). One layer of the double-layer terminals in each local area is flush with the single-layer terminals to form the first row of terminals, and the other layer of the double-layer terminals in each local area is the second row of terminals. The first row of terminals includes a plurality of the single-ended signal terminals S and a plurality of the ground terminals G, and each single-ended signal terminal S has one or two ground terminals G on both sides, and the two ground terminals G have stronger anti-interference capabilities. The second row of terminals in each local area includes at least one differential signal terminal group and a plurality of ground terminals G, and each differential signal terminal group is composed of two differential signal terminals S, and each differential signal terminal group has one or two ground terminals G on both sides, and the two ground terminals G have stronger anti-interference capabilities.

[0025] The double-layer terminal includes a lower terminal and an upper terminal. The single-layer terminals in the remaining terminal slots 14 are flush with the lower terminals to form a row. The single-layer terminals in the remaining terminal slots 14 have the same structure as the lower terminals of the double-layer terminals, and the single-layer terminals in the remaining terminal slots 14 have different structures from the upper terminals of the double-layer terminals (the single-layer terminals can also be flush with the upper terminals, the single-layer terminals have the same structure as the upper terminals, and the single-layer terminals have different structures from the lower terminals). Each of the upper and lower terminals 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 fixing portion 21 of each upper terminal protrudes outward from the outer side of the slot 11 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 contact portion 123 of the upper terminal and the contact portion 123 of the lower terminal are oriented in the same direction, the contact portion 123 of the upper terminal is higher than the contact portion 123 of the lower terminal, the welding portion 124 of the upper terminal is flush with the welding portion 124 of the lower terminal, and the welding portion 124 of the upper terminal of the double-layer terminal and the welding portion 124 of the lower terminal of the double-layer terminal are oriented in opposite directions (the welding portion 124 of the upper terminal can also be oriented in the same direction as the welding portion 124 of the lower terminal). Since the remaining single-layer terminals in the terminal slot 14 are flush with the lower terminal, the welding portions 124 of the remaining single-layer terminals in the terminal slot 14 are oriented in the same direction as the welding portion 124 of the lower terminal of the double-layer terminal (the welding portion 124 of the single-layer terminal can also be oriented in the same direction as the welding portion 124 of the upper terminal).

[0026] The multiple plugs 3 are respectively inserted and fixed in the corresponding terminal slots 14 one by one, and the plugs 3 in each terminal slot 14 are embedded and molded together with the terminals 2 in the terminal slot 14. At the position of the double-layer terminal, there are two terminals 2 (i.e., the lower terminal and the upper terminal) in each terminal slot 14, and the two terminals 2 (i.e., one lower terminal and one upper terminal) in each terminal slot 14 are embedded and molded together with the plugs 3 in the terminal slot 14; at the position of the single-layer terminal, there is only one terminal 2 in each terminal slot 14, and one terminal 2 in each terminal slot 14 is embedded and molded together with the plug 3 in the terminal slot 14. The plugs 3 embedded and molded together with the two terminals 2 and the plugs 3 embedded and molded together with one terminal 2 have the same structure and size, and the structure and size of the terminal slots 14 that accommodate each plug 3 are also the same, making manufacturing more convenient and assembly simpler and faster.

[0027] 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 21 is embedded and molded together with the main board body 31 of the plug 3, and each arm portion 22 extends out of the top of the plug 3. Specifically, the arm portion 22 of the lower terminal extends from the notch 33, and the arm portion 22 of the upper terminal extends from the top of the protruding portion 32 on the side away from the slot 11. The buckling portion 25 of the upper terminal extends out of the main board body 31 of the plug 3, and the plug 3 is firmly fixed in the terminal slot 14 of the insulating body 1 through the dual retaining effect of the buckling portion 25 and the retaining portion 34. The bottom surface of the main body 31 is substantially flush with the bottom surface of the insulating body 1 .

[0028] Compared with the prior art, the beneficial effects of the present invention are mainly reflected in: by locally setting double-layer terminals, the number of terminals is increased on the basis of the same structural space, thereby increasing the signal transmission channel, so that the signal transmission speed is greatly improved; by embedding the terminal 2 and the plug 3 together, only allowing the plug 3 to be fixed in the terminal groove 14 in an inserted and fixed manner, the assembly error rate can be reduced; by making the first row of terminals adopt single-ended signal terminals and use single-ended signals, more single-ended signal terminals can be arranged to improve the signal transmission speed, and by making the second row of terminals adopt differential signal terminals and use differential signals, the anti-interference ability is strong.

[0029] The ear buckle 4 of one of the tower parts 13 of the present embodiment can also be replaced by a metal lock structure 5 with a spring-type anti-retraction structure 51. The ear buckle 4 is buckled and fixed in a buckle groove 61 at the upper part of one side of the electronic module 6 inserted into the slot 11, and the metal lock structure is buckled and fixed in a buckle groove 61 at the lower part of the other side of the electronic module 6 to fix the electronic module 6 (such as Fig.21 and Fig.28 The single-sided ear clip method can save the space occupied by opening the ear clip.

[0030] In other embodiments, Figure 11-12As shown, the first row of terminals includes multiple differential signal terminal groups and multiple grounding terminals G, each differential signal terminal group consists of two differential signal terminals S, and each differential signal terminal group has one or two grounding terminals G on both sides, and the two grounding terminals G have stronger anti-interference ability. The second row of terminals in each of the local areas includes at least one single-ended signal terminal S and multiple grounding terminals G, and each single-ended signal terminal has one or two grounding terminals G on both sides, and the two grounding terminals G have stronger anti-interference ability. By making the first row of terminals dominated by differential signals, the anti-interference ability is strong, and the second row of terminals is supplemented by single-ended signals, there are more signal transmission channels and faster signal transmission speed.

[0031] In other embodiments, Fig.13 As shown, the first row of terminals includes multiple single-ended signal terminals S and multiple ground terminals G, and the second row of terminals in each local area includes at least one single-ended signal terminal S and multiple ground terminals G. There are one or two ground terminals G on both sides of each single-ended signal terminal S, and the two ground terminals G have stronger anti-interference ability. By using single-ended signal terminals in the first row of terminals and transmitting single-ended signals (single-ended signals only need one terminal to transmit signals), more single-ended signal terminals can be arranged, and the second row of terminals uses single-ended signals as a supplement, with more signal transmission channels and faster signal transmission speed.

[0032] In other embodiments, Figure 14-15 As shown, the first row of terminals includes multiple differential signal terminal groups and multiple grounding terminals G, the second row of terminals in each local area includes at least one differential signal terminal group and multiple grounding terminals G, each differential signal terminal group consists of two differential signal terminals S, and each differential signal terminal group has one or two grounding terminals G on both sides, and the two grounding terminals G have stronger anti-interference ability. By making the first row of terminals dominated by differential signals (differential signals require 2 terminals to transmit signals), the anti-interference ability is strong, and the second row of terminals uses differential signals as a supplement, so that there are more signal transmission channels and faster signal transmission speed.

[0033] In other embodiments, Fig.16As shown, the first row of terminals includes multiple differential signal terminal groups, multiple single-ended signal terminals S and multiple ground terminals G, and the second row of terminals in each local area includes at least one differential signal terminal group, at least one single-ended signal terminal S and multiple ground terminals G, each differential signal terminal group consists of two differential signal terminals S, and both sides of each differential signal terminal group and both sides of each single-ended signal terminal S have one or two ground terminals G. By cross-combining the first row of terminals and the second row of terminals with single-ended signals (single-ended signals only need one terminal to transmit signals) and differential signals (differential signals need two terminals to transmit signals), the design is flexible, and within the same space, there are more signal channels and faster signal transmission speed.

[0034] In other embodiments, Figure 17-20 As shown, the terminal slots 14 of the insulating body 1 are of the same size but have different structures.

In the position of the double-layer terminal, the two terminals 2 in each terminal slot 14 are embedded together with a plug, and the plug 3 is inserted and fixed in the terminal slot 14. The structures of the lower terminals and upper terminals of the single-layer terminals and double-layer terminals in the remaining terminal slots 14 are different. By embedding the double-layer terminal with the plug 3 and only holding the plug 3 in the terminal slot 14 by plug-in, the assembly error rate can be reduced. By fixing the single-layer terminal in the terminal slot 14 by plug-in, the embedded molding process can be reduced, and the manufacturing cost can be reduced.

[0035] Each of the single-layer terminals includes a second fixing portion 26, which extends upward to form an arm portion 27, the end of which protrudes toward the slot side to form a contact portion 28, the lower end of which is connected to a second welding portion 29, a bayonet 26 is provided on the second fixing portion 26, a clamping block 141 matching the bayonet 261 is provided on the inner wall of the terminal slot 14, the clamping block 141 connects the two side walls of the terminal slot 14 along the length direction of the insulating body, and one side of the bayonet 261 protrudes out to a clamping point 262 clamped and fixed on the clamping block 141.

The second soldering portion 29 of the single-layer terminal and the first soldering portion 24 of the upper-layer terminal are both facing the outside of the insulating body 1, and the first soldering portion 24 of the lower-layer terminal is facing the inside of the insulating body 1. 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.

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.

[0041] 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, 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.

[0042] The welding portion 24 of the upper terminal and the welding portion 24 of the lower terminal are oriented in the same direction, and the welding portion 24 of the single-layer terminal and the welding portion 24 of the lower terminal are oriented in the same direction.
