Description

Colloidal structure of electrical connector

The present invention relates to a colloid structure for an electrical connector that can improve the quality of high-frequency signal transmission.

According to the traditional connector structure used for multimedia signal transmission, such as the structure of the USB connector in the Republic of China Patent Publication No. M509461, it mainly includes an outer shielding shell, an inner shielding shell, an insulating gel and a transmission conductor set on the insulating gel. Its main feature is that the outer shielding shell completely covers the inner shielding shell, which can effectively suppress the transmission conductor set contained in the inner shielding shell. To address the EMI and RFI interference issues caused by the shielding, the outer shielding case includes a base with an opening. A shielding portion extends from the base away from the opening. The shielding portion has a first inclined portion and a second inclined portion inclined in an opposite direction to the first inclined portion. In addition to the aforementioned advantages, the first and second inclined portions can effectively save installation space.

However, the above-mentioned USB connector structure does have the following problems and deficiencies when in use and needs to be improved:

Because it's a side-mounted connector, the terminals of the transmission conductor assembly inevitably have different lengths. These varying lengths result in different signal transmission speeds. This speed difference means the signal takes different amounts of time to reach the circuit board after passing through the terminals. This leads to unstable high-frequency signal transmission quality.

Therefore, how to solve the above-mentioned problems and shortcomings in usage is the direction that the applicant of this invention and related manufacturers in this industry are eager to research and improve.

The main purpose of this invention is to provide a method that allows the signal from a side-mounted electrical connector to reach the soldered portion of the transmission conductor assembly at the same time, thereby improving the quality of high-frequency signals.

The main structure of the present invention capable of achieving the above-mentioned objectives includes a transmission conductor assembly, a transmission conductor assembly contact portion, a transmission conductor assembly base portion, a transmission conductor assembly bending guide portion, a transmission conductor assembly welding portion, a front transmission conductor assembly contact portion, a rear transmission conductor assembly contact portion, and an insulating colloid. The insulating colloid includes a tongue portion and a base portion. The tongue portion includes a first tongue portion. The transmission conductor group contact portion is sequentially extended from one side to form a transmission conductor group base, a transmission conductor group bending guide portion, and a transmission conductor group welding portion, and the transmission conductor group contact portion includes the front row transmission conductor group contact portion and the rear row transmission conductor group contact portion, and the insulating gel The tongue portion covers the transmission conductor assembly, with the tongue portion covering the transmission conductor assembly contact portion and the transmission conductor assembly base, and the base portion covering the transmission conductor assembly bend guide portion. The first tongue portion covers the transmission conductor assembly base, while the rear contact perforations expose the rear transmission conductor assembly contact portion. The tongue positioning holes correspond to the transmission conductor assembly base and prevent the transmission conductor assembly from shifting during the manufacturing process. The second tongue portion extends from the first tongue portion and includes a plurality of front contact slots for exposing the front transmission conductor assembly contact portion. Notably, the first tongue portion includes at least one tongue cutout portion, which corresponds to the transmission conductor assembly base, exposing the transmission conductor assembly base to increase transmission speed.

When the signal from the transmission conductor assembly passes through the transmission conductor assembly contact portion, the transmission conductor assembly base, and the transmission conductor assembly bend guide portion, the time it takes to finally reach the transmission conductor assembly soldering portion is often inconsistent. However, the tongue cutout increases the speed of the signal originally passing through the transmission conductor assembly base, ensuring that the signal reaches the transmission conductor assembly soldering portion at the same time, thereby improving the quality of high-frequency signal transmission.

The above-mentioned technology overcomes the problem of conventional USB connectors, which, due to their side-mounted design, inevitably result in different lengths for the terminals of the transmission conductor assembly. These different lengths lead to different transmission speeds for the signal. These speed differences mean that the signal takes different times to reach the circuit board after passing through the terminals, leading to unstable high-frequency signal transmission quality. This solves the practical and advanced advantages of the present invention.

The four differential signal transmission conductor bases 29 and the following transmission conductor group bending guide portion 11c are arranged in sequence: a first differential signal transmission conductor guide portion 20a, a second differential signal transmission conductor guide portion 21a provided on one side of the first differential signal transmission conductor guide portion 20a, a power transmission conductor guide portion 22a provided on one side of the second differential signal transmission conductor guide portion 21a, a first ground transmission conductor guide portion 23a provided on one side of the power transmission conductor guide portion 22a, a first signal transmission conductor guide portion 23a provided on one side of the first ground transmission conductor guide portion 23a, and a second differential signal transmission conductor guide portion 21a. The first signal transmission conductor guide 24a comprises a first signal transmission conductor guide 25a disposed on one side of the first signal transmission conductor guide 24a; a third ground transmission conductor guide 27a disposed on one side of the second signal transmission conductor guide 25a and connected to the second ground transmission conductor base 26 and the third ground transmission conductor base 27; a third differential signal transmission conductor guide 28a disposed on one side of the third ground transmission conductor guide 27a; and a fourth differential signal transmission conductor guide 29a disposed on one side of the third differential signal transmission conductor guide 28a.

A transmission conductor assembly bending guide portion 11c extending from the transmission conductor assembly base portion 11b away from the transmission conductor assembly contact portion 11a;

A transmission conductor assembly welding portion 11d formed by extending the transmission conductor assembly bending guide portion 11c away from the transmission conductor assembly base portion 11b;

An insulating colloid 3 covering the transmission conductor assembly 1 includes:

A tongue portion 31 covering the transmission conductor group contact portion 11a and the transmission conductor group base portion 11b, the tongue portion 31 including a first tongue portion 311 covering the transmission conductor group base portion 11b, and a second tongue portion 312 extending from the first tongue portion 311 away from the base portion 32 described below and for arranging the front row transmission conductor group contact portion 111a. The first tongue portion 311 includes a plurality of rear rows for exposing the rear row transmission conductor group contact portion 112a. The second tongue portion 312 includes a plurality of contact holes 3111, several tongue positioning holes 3112 corresponding to the base portion 11b of the transmission conductor assembly to prevent the transmission conductor assembly 1 from shifting during the manufacturing process, and a tongue cutout portion 3113, at least one of which corresponds to the base portion 11b of the transmission conductor assembly to expose the base portion 11b of the transmission conductor assembly to increase transmission speed. The second tongue portion 312 includes a plurality of front contact slots 3121 for exposing the front row transmission conductor assembly contact portion 111a.

A base portion 32 connected to the tongue portion 31 and covering the transmission conductor assembly bending guide portion 11c.

In this embodiment, the tongue cutout portion 3113 is located above the second differential signal transmission conductor base 21.

During the manufacturing process, when embedding the transmission conductor assembly 1 within the insulating gel 3, the assembly is positioned and fixed using a pin through the tongue positioning hole 3112. This prevents the assembly from shifting during molding. The front transmission conductor assembly contact portion 111a is positioned within the front contact groove 3121, and the rear transmission conductor assembly contact portion 112a is positioned within the rear contact through-hole 3111. The transmission conductor assembly welding portion 11d is exposed on one side of the insulating gel 3, and the transmission conductor assembly bending guide portion 11c forms a side-standing electrical connector.

When the electrical connector of this embodiment is inserted into the counterpart connector, the front transmission conductor group contact portion 111a and the rear transmission conductor group contact portion 112a of the transmission conductor group contact portion 11a receive the signal, which is then sequentially transmitted through the transmission conductor group base portion 11b and the transmission conductor group bending guide portion 11c to the transmission conductor group welding portion 11d. Furthermore, the signal sequentially passes through the first differential signal transmission conductor base portion 20 and the first differential signal transmission conductor guide portion 20a; and sequentially passes through the second differential signal transmission conductor base portion 21 , and the second differential signal transmission conductor guide portion 21a; sequentially passing through the third differential signal transmission conductor base 28 and the third differential signal transmission conductor guide portion 28a; sequentially passing through the fourth differential signal transmission conductor base 29 and the fourth differential signal transmission conductor guide portion 29a; sequentially passing through the first signal transmission conductor base 24 and the first signal transmission conductor guide portion 24a; sequentially passing through the second signal transmission conductor base 25 and the second signal transmission conductor guide portion 25a; and the aforementioned signals will eventually reach the transmission conductor assembly welding portion 11d.

It is worth mentioning that in this case, a tongue hollow portion 3113 is formed on the base portion 11b of the transmission conductor assembly, and is formed above the second differential signal transmission conductor base 21 as an example. Since the common length of the second differential signal transmission conductor base 21 and the second differential signal transmission conductor guide portion 21a is greater than the common length of the first differential signal transmission conductor base 20 and the first differential signal transmission conductor guide portion 20a, the length of the second differential signal transmission conductor base 21 and the second differential signal transmission conductor guide portion 21a is much greater than the length of the first differential signal transmission conductor base 20 and the first differential signal transmission conductor guide portion 20a in the signal transmission path. In addition, due to the dielectric constant and dissipation coefficient of the insulating gel 3, the length of the second differential signal transmission conductor base 21 and the second differential signal transmission conductor guide portion 21a is much greater than the length of the first differential signal transmission conductor base 20 and the first differential signal transmission conductor guide portion 20a. Factor) will directly affect the speed and quality of the transmission signal, making the signal passing through the second differential signal transmission conductor base 21 and the second differential signal transmission conductor guide portion 21a reach the transmission conductor assembly welding portion 11d slower than the signal passing through the first differential signal transmission conductor base 20 and the first differential signal transmission conductor guide portion 20a, thereby generating signal imbalance and causing a decrease in the high-frequency signal transmission quality. In this case, the second differential signal transmission conductor base 21 is exposed to the outside by the tongue hollow portion 3113. This approach is based on the dielectric constant of air. The dielectric constant (εr) = 1.00053, which is just above the dielectric constant of a vacuum, prevents signals passing through the second differential signal transmission conductor base 21 from being affected by the dielectric of the insulating gel 3, effectively improving signal delay and increasing transmission speed. This allows the signal passing through the second differential signal transmission conductor base 21 and the second differential signal transmission conductor guide portion 21a to reach the transmission conductor assembly solder portion 11d at the same time as the signal passing through the first differential signal transmission conductor base 20 and the first differential signal transmission conductor guide portion 20a, achieving signal balance and effectively improving the stability and quality of high-frequency transmission signals.

Please refer to the fourth figure, which is a plan view of the second preferred embodiment of the present invention. It can be clearly seen from the figure that the present embodiment is different from the above embodiments in that the base portion 32 of the present embodiment has a plurality of base positioning holes 321 and a plurality of base hollow portions 322 located on the sides of the base positioning holes 321. In other words, each base positioning hole 321 is mainly used for the top pin to press the transmission conductor assembly during the manufacturing process, and the tongue positioning hole 3112 can further increase the stability of its positioning. In addition, the base hollow portion 322 can be used as the top pin positioning hole 321 during the manufacturing process. In addition, the influence of the transmission medium on the bending guide portion of the transmission conductor assembly can be reduced, thereby increasing the transmission speed, while maintaining the same time required to reach the welding portion 11d of the transmission conductor assembly. The base cutout 322 of this embodiment is provided above the third differential signal transmission conductor guide portion 28a and the fourth differential signal transmission conductor guide portion 29a, for example, to effectively accelerate the signal passing through the third differential signal transmission conductor base, the third differential signal transmission conductor guide portion 28a, the fourth differential signal transmission conductor base, and the fourth differential signal transmission conductor guide portion 29a.

Please refer to FIG5, which is a plan view of the third preferred embodiment of the present invention. It can be clearly seen from the figure that the present embodiment is different from the aforementioned embodiment in that the base portion 32 of the present embodiment has a reinforced hollow portion 323, which includes a transverse hollow portion 3231 and a longitudinal hollow portion 3232 communicating with the transverse hollow portion 3231, and the transverse hollow portion 3231 is located at a position corresponding to the side of the transmission conductor group bending guide portion 11c adjacent to the transmission conductor group welding portion 11d, and the longitudinal hollow portion 3232 is located at a position corresponding to the second differential signal transmission conductor guide portion 21a; thereby, by strengthening the hollow portion The transverse cutout 3231 in section 323 further increases the signal speed of the transmission conductor assembly's bent guide section 11c, accelerating transmission speed. The longitudinal cutout 3232 further accelerates the signal passing through the second differential signal transmission conductor guide section 21a. This allows the signal passing through the second differential signal transmission conductor base 21 and the second differential signal transmission conductor guide section 21a to reach the transmission conductor assembly soldering portion 11d at the same time as the signal passing through the first differential signal transmission conductor base and the first differential signal transmission conductor guide section 20a, further enhancing the stability and quality of the high-frequency output signal.

Please refer to Figure 6, which is a perspective view of the fourth preferred embodiment of the present invention. As can be clearly seen from the figure, this embodiment differs from the previous embodiments in that the insulating colloid 3 is covered with a shielding shell 4. The shielding shell 4 can effectively shield noise and prevent it from affecting other electronic components.

Please refer to Figure 7, which is a plan view of the fifth preferred embodiment of the present invention. As can be clearly seen from the figure, this embodiment differs from the previous embodiments in that the shielding housing 4 of this embodiment includes a shielding housing cutout 41 corresponding to the reinforced cutout 323. This design of the shielding housing cutout 41 allows signals to pass through the transverse cutout 3231 and the longitudinal cutout 3232 without obstruction, resulting in faster and more balanced transmission speeds and improved high-frequency transmission quality.

Please refer to FIG8, which is a planar exploded view of the sixth preferred embodiment of the present invention. It can be clearly seen from the figure that this embodiment is different from the above embodiments in that, in addition to including all the technical features of the first preferred embodiment, this embodiment also includes a plurality of base positioning holes 321, a plurality of base hollow portions 322, and a reinforced hollow portion 323 on the base portion 32, wherein the base hollow portion 322 is located corresponding to the transmission guide. The reinforcing hollow portion 323 includes a transverse hollow portion 3231 and a longitudinal hollow portion 3232 communicating with the transverse hollow portion 3231. The transverse hollow portion 3231 is located at a position corresponding to the side of the transmission conductor assembly bending guide portion 11c adjacent to the transmission conductor assembly welding portion 11d. The longitudinal hollow portion 3232 is located at a position corresponding to the second differential signal transmission conductor guide portion 21a. The insulating colloid 3 is covered with a shielding shell 4, and the shielding shell 4 has a shielding shell hollow portion 41 corresponding to the position of the reinforced hollow portion 323. Thus, this embodiment integrates all the technical features of the aforementioned embodiments, that is, this embodiment exposes the second differential signal transmission conductor base 21 to the outside through the tongue hollow portion 3113, so that the signal passing through the second differential signal transmission conductor base 21 will not be affected by the insulating colloid 3. The medium influence can increase the transmission speed. In this way, the time it takes for the signal passing through the second differential signal transmission conductor base 21 and the second differential signal transmission conductor guide portion 21a to reach the transmission conductor assembly welding portion 11d can be the same as the time it takes for the signal passing through the first differential signal transmission conductor base 20 and the first differential signal transmission conductor guide portion 20a, thereby achieving signal balance and effectively improving the stability and quality of the high-frequency transmission signal. Furthermore, the design of the base hollow portion 322 allows the signal passing through the fourth differential signal transmission conductor base 29 and the fourth differential signal transmission conductor guide portion 29a to reach the transmission conductor assembly welding portion 11d at the same time as the signal passing through the third differential signal transmission conductor base 28 and the third differential signal transmission conductor guide portion 28a. Furthermore, the design of the transverse cutout 3231 within the reinforced cutout 323 further increases the speed at which the transmission conductor assembly bends the guide portion 11c, further accelerating transmission speed. The design of the longitudinal cutout 3232 within the reinforced cutout 323 further enhances the stability and quality of the high-frequency output signal. Furthermore, the shielded housing cutout 41 allows signals to pass through the transverse and longitudinal cutouts 3231 and 3232 without obstruction, resulting in faster and more balanced transmission speeds and improved high-frequency transmission quality.
