Description

Technical Field

[0001] The utility model relates to an electrical connector which strengthens the noise venting function, effectively reduces electromagnetic interference, radio frequency interference and the contact impedance of external contact components, optimizes high-frequency characteristics, can not only accept repeated assembly processes, but also ensure good contact effects of external contact components and increase the external noise venting.

Background Art

[0002] The USB transmission line is the current mainstream and quite popular signal transmission line specification, and its connectors have many different types, such as type A, type B and type C, etc. Since type C has the advantages of being able to be inserted in either direction, a transmission speed of up to 10 Gbit / s, a power supply efficiency of up to 100 W, and being able to replace the 3.5 mm audio jack, it is obvious that the popularity of USB type C is irresistible.

[0003] However, when the above-mentioned USB type C and type A are in use, there are indeed the following problems and deficiencies to be improved:

[0004] Because USB type C can support a transmission speed of up to 10 Gbit / s, various noise interferences are easily generated, such as electromagnetic interference and radio frequency interference. Although there are optimization projects for the foregoing interferences in the market, the noise venting ability is not good, so that the overall effect is not obvious and the noise interference is still serious. In addition, general electrical connectors are fixedly arranged with external electronic components, such as screwing, to form a pipeline for increasing noise venting by means of hard contact. However, the biggest problem with this method is that when the electrical connector is assembled incorrectly and needs to be reassembled, the user has to use tools to remove the screws again, and the process is cumbersome. Moreover, even if it has the function of increasing noise venting, because it belongs to hard contact, there will be a problem of inaccurate contact during reassembly, thereby reducing the noise venting function; in addition, USB type A also has interference problems, mainly because the noise venting degree is not good. Even if the part of the shielding shell is improved to solve the noise venting problem, the design direction is mainly hard contact, which cannot be reassembled and has a poor contact effect.

[0005] How to solve the above problems and deficiencies is the direction that the applicant of the present utility model and related manufacturers in this industry are eager to research and improve.

Content of the Utility Model

[0006] The purpose of the utility model is to provide an electrical connector which strengthens the noise venting function, effectively reduces electromagnetic interference, radio frequency interference and the contact impedance of external contact components, optimizes high-frequency characteristics, can not only accept repeated assembly processes, but also ensure good contact effects of external contact components and increase the external noise venting.

[0007] The main purpose structure includes a shielding housing, and at least one outer contact assembly is formed at at least one side for contacting an electronic component with conductive characteristics located outside the shielding housing. The outer contact assembly further includes an elastic part extending from the shielding housing. The end of the elastic part integrally extends to form a base part, and the base part integrally extends at the end facing away from the elastic part to form a contact part. Furthermore, an insulating colloid group is accommodated in the shielding housing. The insulating colloid group has a tongue part, and an insertion space for inserting a male connector is formed between the periphery of the tongue part and the inner side wall of the shielding housing. And a transmission conductor group conforming to the USB Type-C transmission protocol or the USB Type-A transmission protocol is provided on the insulating colloid group. The transmission conductor group includes a contact part group provided on the tongue part. One end of the contact part group extends to form a base part group, and the base part group extends at the end facing away from the contact part group to form a welding part group, and the welding part group is arranged in a single row.

[0008] When the installation position of the electrical connector is incorrect during the assembly process, resulting in an offset problem or other types of mistakes, due to the elastic part of the outer contact assembly, when the electrical connector makes a mistake during the assembly process, it can still be reassembled and will not be affected by the outer contact assembly and unable to be reassembled. At the same time, it can ensure that the outer contact assembly has a good contact effect. Also, after the electrical connector is assembled, it can actively or passively contact the electronic component through the outer contact assembly. In this way, the electrical connector can have more paths to vent noise, thereby achieving an increased venting efficiency, effectively reducing electromagnetic interference, radio frequency interference, and the contact impedance of the outer contact assembly, and optimizing high-frequency characteristics.

[0009] With the above technology, for the problems existing in the conventional USB Type-C, because the USB Type-C can support a transmission speed of up to 10 Gbit / s, various noise interferences are likely to occur, such as electromagnetic interference and radio frequency interference. Although there are optimization projects for the aforementioned interferences in the market, the noise venting ability is not good, so the overall effect is not significant, and the noise interference is still serious. In addition, general electrical connectors are fixedly arranged with external electronic components, such as screwing, to form a pipeline for increasing noise venting in a hard contact manner. However, the biggest problem with this method is that when the electrical connector is assembled incorrectly and needs to be reassembled, the user must use tools to remove the screws again, and the process is cumbersome. Moreover, even if it has the function of increasing noise venting, because it is a hard contact, there will be a problem of uncertain contact during reassembly, thereby reducing the noise venting function; in addition, the USB Type-A also has interference problems, mainly because the degree of noise venting is not good. Even if there are improvements to the noise venting problem for the shielding housing part, the design direction is mainly hard contact and cannot be reassembled.

Detailed implementation manners

[0019] Please refer to Figures 1 to 3 As shown, a perspective view to a schematic view of the implementation of the first preferred embodiment of the present utility model. It can be clearly seen from the figure that the electrical connector includes:

[0020] A shielding housing 1, at least one outer contact assembly 11 is formed at least on one side for contacting an electronic component 4 having a conductive property outside the shielding housing 1. The outer contact assembly 11 includes an elastic portion 111 extending from the shielding housing 1, a base portion 112 formed in the extending direction of the end of the elastic portion 111, and a contact portion 113 formed in the extending direction of the base portion 112;

[0021] An insulating colloid group 2 received in the shielding housing 1, having a tongue portion 21. An insertion space 22 for inserting a male connector is formed between the periphery of the tongue portion 21 and the inner side wall of the shielding housing 1; and

[0022] A transmission conductor assembly 3, combined with the insulating gel assembly 2 and compliant with the USB Type-C transmission protocol or the USB Type-A transmission protocol, includes a contact assembly 31 disposed on the tongue 21, a base assembly 32 extending from one end of the contact assembly 31, and a soldering assembly 33 extending from the end of the base assembly 32 away from the contact assembly 31. The soldering assembly 33 is arranged in a single row.

[0023] The elastic portion 111 is formed to extend toward the outside of the shielding shell 1 .

[0024] The elastic portion 111 is close to the opening side of the shielding shell 1 .

[0025] In this embodiment, the welding portion group 33 has 26 welding legs as an example.

[0026] In this embodiment, the electronic component 4 is an iron shell of the device. Of course, the electronic component 4 can also be one of conductive aluminum foil, copper foil, polyester film, conductive foam, metal baffle, or metal shielding.

[0027] In this embodiment, two external contact components 11 are used as an example. Of course, there can also be only one or more external contact components 11. This is just a simple change in quantity.

[0028] When assembling the electrical connector into the electronic component 4, if the installation position is incorrect due to human intervention or other factors, the electrical connector can be reinstalled. This is because the external contact element 11 of this embodiment has an elastic function through the design of the elastic portion 111, which allows for a soft contact when contacting the electronic component 4. That is, even if the electronic component 4 squeezes the external contact element 11 and causes deformation, the external contact element 11 itself is elastic. When the electrical connector is removed from the electronic component 4, the external contact element 11 can still return to its original shape due to its inherent elasticity, allowing it to contact the electronic component 4 again during the next installation. Compared with the hard contact of the prior art, the soft contact method of this embodiment allows the electrical connector to be repeatedly installed without the problem of poor contact between the external contact element 11 and the electronic component 4. This ensures good contact performance of the external contact element 11, effectively stabilizes the noise dissipation channel, thereby increasing the dissipation efficiency and extending its life. No tools or screws are required to increase the dissipation path, making it very convenient overall.

[0029] When the electrical connector is fully installed inside the electronic component 4, the electronic component 4 will abut against and squeeze the outer contact assembly 11 inward. At this time, the elastic part 111 will deform, and cooperate with the base part 112 to produce an elastic support effect, so that when the contact part 113 is squeezed by the electronic component 4, it will firmly contact the electronic component 4 without detachment problems, achieving the function of increasing the grounding path and thus increasing the noise dissipation, effectively reducing electromagnetic interference, radio frequency interference, and the contact impedance of the outer contact assembly, and optimizing the high-frequency characteristics.

[0030] In addition, in this embodiment, the transmission conductor group 3 of the electrical connector takes the USB Type-C as an example, and can also be USB Type-A, both of which are within the scope of protection of this case. Moreover, the electrical connector of this case conforms to the USB Type-C transmission protocol and is set as a female socket, so the noise dissipation problem of the USB Type-C female socket electrical connector can be improved. Not only that, because the welding part group 33 of this case is arranged in a single row, such a design can help improve the factory manufacturing speed.

[0031] Please refer to Figure 4 and Figure 5 As shown in the perspective view and the implementation schematic diagram of the second preferred embodiment, it can be clearly seen from the figure that the contact part 113 of this embodiment has a first elastic bending part 1131 connected to the base part 112, an inclined wall part 1132 formed in the extending direction of the end of the first elastic bending part 1131, a second elastic bending part 1133 formed on the side of the inclined wall part 1132 facing away from the first elastic bending part 1131, and a contact part 1134 formed on the side of the second elastic bending part 1133 facing away from the inclined wall part 1132. And the elastic part 111 is formed by longitudinally bending and extending from the opening side edge of the shielding housing 1. Thus, when the outer contact assembly 11 of the electrical connector contacts the electronic component 4, the electronic component 4 will squeeze the contact part 1134, causing the second elastic bending part 1133 and the first elastic bending part 1131 to deform, and the inclined wall part 1132 to displace, so that the outer contact assembly 11 forms an elastic outer contact assembly 11 and contacts the electronic component 4 in a soft contact manner. Therefore, the electrical connector can be repeatedly installed and has the advantage of reliable contact. Other advantages are as described in the foregoing embodiments, so they will not be elaborated here. Of course, this embodiment takes one as an example. When there are two outer contact assemblies 11, they can be respectively located above and below the opening, increasing more noise dissipation paths and achieving a better noise dissipation function.

[0032] Please refer to Figure 6 and Figure 7As shown in the perspective view and implementation schematic diagram of the third preferred embodiment, it can be clearly seen from the figure that the elastic part 111 of this embodiment extends towards the inside of the shielding housing 1, and there is a holding part 114 between the base part 112 and the contact part 113 for the male connector 5 to abut against. By the male connector 5 abutting against the holding part 114, the elastic part 111 is deformed, so that the contact part 113 contacts the electronic component 4, and the base part 112 extends obliquely towards the opening side away from the shielding housing 1. And the electronic component 4 takes the conductor area on the circuit board as an example in this embodiment. Thus, when the male connector 5 and the electrical connector of this case are inserted into each other, the male shielding housing 51 of the male connector 5 will be located in the insertion space 22 and cover the tongue part 21. And at the same time, the male shielding housing 51 will abut against the holding part 114, pushing the contact part 113 from the inside of the shielding housing 1 towards the outside, so that the contact part 113 contacts the electronic component 4, achieving the advantage of increasing noise dissipation.

[0033] Please refer to Figure 8 As shown in the implementation schematic diagram of the fourth preferred embodiment of the present utility model, it can be clearly seen from the figure that in addition to being arranged in a single row, the number of welding legs of the welding part group 33 in this embodiment can be 16, which means that the welding legs of this case can be 16 or more. For example, 26 welding legs are taken as an example in the previous embodiment. Therefore, this case is mainly applied to USB Type-C electrical connectors with 16 or more welding legs.

[0034] Please refer to Figure 9 As shown in the implementation schematic diagram of the fifth preferred embodiment of the present utility model, it can be clearly seen from the figure that the outer contact components 11 of this embodiment are respectively arranged on the upper side and the lower side of the shielding housing 1. Structurally, the elastic part 111 of the outer contact component 11 on the upper side extends towards the outside of the shielding housing 1, and the elastic part 111 of the outer contact component 11 on the lower side extends towards the inside of the shielding housing 1. That is to say, in this case, the outer contact components 11 can be arranged on both the upper and lower sides of the shielding housing 1 at the same time to increase more noise dissipation paths and achieve better effects. Of course, the outer contact components 11 can also be arranged at the opening side edge and the lower side of the shielding housing 1, and the variation of the arrangement is not limited.
