Description

Technical Field

[0001] The utility model relates to the technical field of electronic accessories, in particular to an integrated wire-to-board connector. Background Art

[0002] As the transmission rate of many connectors is getting higher and higher, in order to ensure the transmission rate, there are relatively high requirements for the welding between the connector and the circuit board, and there are also high requirements for the welding between the circuit board and the cable core wire. Not only is it required that there should be no cold welding between the cable core wire and the circuit board, but also that the solder joints should be smooth and round.

[0003] The area of ​​the corresponding pad of the circuit board is often very small due to performance parameter requirements. The pad will fall off directly if you are not careful during welding. At the same time, it is difficult to ensure that the welding end of the cable core wire does not go beyond the pad of the circuit board. Because the length of the core wire stripped from the cable is short, a correspondingly large torsional stress will be generated. The large torsional stress will cause the welding end of the cable core wire to easily go beyond the pad of the circuit board. At the same time, even if the welding is completely qualified, if the stress cannot be limited, the torsional stress of the cable core wire itself will pull the welded pad off.

[0004] There are many practical difficulties in producing such high-speed connectors. Even with the help of special welding machines, auxiliary wire clamps, glue dispensers for reinforcement, etc., the production is still very difficult. Not only is it labor-intensive and time-consuming, but it is also difficult to guarantee the yield rate. Finally, qualified products must be selected through full inspection. Therefore, the cost of high-speed connectors is relatively high in processing costs, yield rate costs, and full inspection costs. Utility Model Content

[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0042] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0043] As the transmission rates of many data cables are getting higher and higher, such as HDMI2.1's transmission rate is 48Gbps, and USB4's transmission rate is 40Gbps. In order to ensure the transmission rate, not only are there relatively high requirements for the welding between the connector and the circuit board, but also for the welding between the circuit board and the cable core wire. Not only must there be no cold solder joints between the cable core wire and the circuit board, but the solder joints must be smooth and round, and the cable core wire welding ends must not go beyond the circuit board pads. To ensure the rate performance requirements, the length of the core wire stripped from the cable should be as short as possible.

[0044] The area of ​​the corresponding pad of the circuit board is often very small due to performance parameter requirements, and common sizes are 2*0.4mm and 1.5*0.3mm. With such a small pad area, the pad will fall off directly if you are not careful during welding, and it is also difficult to ensure that the welding end of the cable core wire does not go beyond the pad of the circuit board. Because the length of the core wire stripped from the cable is short, a correspondingly large torsional stress will be generated. The large torsional stress will cause the welding end of the cable core wire to easily go beyond the pad of the circuit board. At the same time, even if the welding is completely qualified, if the stress cannot be limited, the torsional stress of the cable core wire itself will pull the welded pad off.

[0045] There are many practical difficulties in producing such high-speed data cables. Even with the help of special welding machines, auxiliary wire clamps, glue dispensers for reinforcement, etc., the production is still very difficult. Not only is it labor-intensive and time-consuming, but it is also difficult to guarantee the yield rate. Finally, qualified products must be selected through full inspection. Therefore, the cost of high-end data cables is more of processing cost, yield rate cost and full inspection cost, and the cost of raw materials is not the most important price factor.

[0046] In view of this, the present invention provides an integrated wire-to-board connector 100 .

[0047] See also Figures 2 to 4 In one embodiment of the utility model, the integrated wire-to-board connector 100 includes a plastic part 1, the plastic part 1 includes a main body 11, a first wire pressing part 12 and a second wire pressing part 13, the first wire pressing part 12 and the second wire pressing part 13 are respectively located on opposite sides of the main body 11, and a wire placement space 14 is formed between the first wire pressing part 12 and the second wire pressing part 13 and the main body 11, and a circuit board mounting compartment 111 is opened in the middle of the main body 11, and the main body 11 is provided with at least two first hooks 112 protruding toward the first wire pressing part 12, and at least two of the first hooks 112 are easily connected to the first wire pressing part 12, and the main body 11 is provided with at least two second hooks 113 protruding toward the second wire pressing part 13, and at least two of the second hooks 113 are easily connected to the second wire pressing part 13. The easily breakable connection between the first hook 112 and the first wire pressing part 12 may be a connection having a notch so that the connection between the first hook 112 and the first wire pressing part 12 is thinner, or a connection between the first hook 112 and the first wire pressing part 12 may be a connection having an easily tearable structure, or a connection having a plurality of continuous tearing openings, which is not specifically limited here.

[0048] It should be noted that the integrated wire-to-board connector 100 is a semi-finished connector structure suitable for the data cable 300. The main body 11 of the integrated wire-to-board connector 100 is divided into a plastic part 1 for accommodating the core wire 31 of the data cable 300, and the plastic part 1 also serves to protect and insulate the core wire 31. In this embodiment, the plastic part 1 includes a main body 11, a first wire pressing part 12, and a second wire pressing part 13, wherein a wire placement space 14 is formed between the first wire pressing part 12 and the second wire pressing part 13 and the main body 11, respectively, so that the core wire 31 can be placed in the wire placement space 14.

[0049] Furthermore, the first wire pressing portion 12 is provided with a first opening corresponding to the first hook 112 , and the second wire pressing portion 13 is provided with a second opening corresponding to the second hook 113 .

[0050] Specifically, the first wire pressing part 12 is connected to the main body 11 by at least two first hooks 112, and the second wire pressing part 13 is connected to the main body 11 by at least two second hooks 113, wherein the number of the first hook 112 and the second hook 113 is at least set to two, and certainly can also be four or more, in the present embodiment, the number of the first hook 112 and the second hook 113 is both set to four. In addition, the length of at least two first hooks 112 (i.e. the length of the first hook 112 from the main body 11 to the first wire pressing part 12 direction) can be the same or different, and the length of at least two second hooks 113 (i.e. the length of the second hook 113 from the main body 11 to the second wire pressing part 13 direction) can be the same or different. After the core wire 31 is placed respectively, pressure can be applied to the first wire pressing part 12 and the second wire pressing part 13 to break the fragile connection between the first hook 112 and the first wire pressing part 12, and pressure can be continued to be applied to the first wire pressing part 12 and the second wire pressing part 13 to make the first hook 112 pass through the first wire pressing part 12. Therefore, a first opening 125 is provided on the first wire pressing part 12 to avoid the first hook 112 passing through the first wire pressing part 12, and the first opening 125 and the first hook 112 correspond one-to-one. In addition, the second hook 113 also passes through the second wire pressing part 13, so a second opening 135 is provided on the second wire pressing part 13 to avoid the second hook 113 passing through the second wire pressing part 13, and the second opening 135 and the second hook 113 correspond one-to-one. Taking into account that the plastic part 1 is made of plastic material, the first hook 112 and the second hook 113 are also set to be made of plastic material. When at least two first hooks 112 pass through the first wire-pressing portion 12, at least two first hooks 112 are squeezed and elastically deformed by the first wire-pressing portion 12, and further, the first wire-pressing portion 12 is buckled on the main body 11 by at least two first hooks 112; when at least two second hooks 113 pass through the second wire-pressing portion 13, at least two second hooks 113 are squeezed and elastically deformed by the second wire-pressing portion 13, and further, the second wire-pressing portion 13 is buckled on the main body 11 by at least two second hooks 113.

[0051] Through the above-mentioned matching method, the core wire 31 can be fixed between the first wire pressing part 12 and the main body 11 and between the second wire pressing part 13 and the main body 11, and a circuit board installation compartment 111 is opened between the main body 11. The circuit board installation compartment 111 is used to install the circuit board 5, so that the core wire 31 can be crimped on the circuit board 5, thereby replacing the process of welding the core wire 31 on the circuit board 5. In this way, the risk of the circuit board pad welding falling off can be effectively avoided. At the same time, the crimping force can fully ensure the smooth connection between the end of the core wire 31 and the circuit board electrical connection plate. The data cable 300 made of this integrated wire-to-board connector 100 can improve production efficiency, save time and labor, improve the yield rate, simplify the performance testing steps, and thus greatly reduce processing costs and production difficulties.

[0052] The technical solution of the present invention is to provide a wire placement space 14 between the first wire pressing portion 12 and the main body 11 and between the second wire pressing portion 13 and the main body 11. By crimping the core wire 31 onto the circuit board 5 instead of welding the core wire 31 onto the circuit board 5, the risk of the circuit board pad falling off can be effectively avoided. At the same time, the crimping force can fully ensure the smooth connection between the end of the core wire 31 and the electrical connection disk of the circuit board. The data cable 300 made of the integrated wire-to-board connector 100 can improve production efficiency, save time and labor, increase the yield rate, simplify the performance testing steps, and thus greatly reduce processing costs and production difficulties.
