Description

Connector terminal structure

This creation relates to a terminal structure of a connector, in particular to a three-layer terminal structure of a connector.

Connectors are electromechanical components that connect conductors or wires with appropriate counterpart components to realize circuit connection and disconnection. The connector transmits signals or current through its internal terminal structure. Currently, there are many types of connectors on the market, and the upper and lower terminal structures inside the connectors are usually single-layer terminal structures. Generally speaking, the terminal is designed to achieve higher current and signal density as much as possible. The size of the current that the terminal can carry is positively related to the cross-sectional area of the terminal. The larger the cross-sectional area of the terminal, the greater the current that can flow.

Although the increase in the cross-sectional area of the terminal can increase the current flowing, it is under the premise of the same length. The increase in the cross-sectional area of the terminal means that the positive force generated by the terminal during the plug-in process of the connector also increases (the positive force is positively related to the width and thickness of the terminal cross section). The increase in the positive force will increase the insertion and extraction force of the connector during the insertion process, which will cause inconvenience to the user in use. And if the positive force of the terminal is too large, its fatigue life will be adversely affected.

Therefore, how to improve the terminal structure and increase the current carrying current of the terminal while maintaining a proper forward force is a problem that still needs to be solved by those skilled in the art.

However, this creation is not limited to the above-mentioned examples.

The left and right (or first axial) relative positions of the first elastic arm 111, the second elastic arm 121, and the third elastic arm 131 in the foregoing embodiment are for illustration only, and not limited thereto; specifically, The positional relationship of the first elastic arm 111, the second elastic arm 121, and the third elastic arm 131 is misaligned with each other in the first axial direction. The first torso 112, the second torso 122 and the third torso 132 are in contact and overlap up and down (or in the second axis), for example: using laser welding to electrically connect them together to carry current together . Furthermore, the width of the first trunk 112 is greater than the width of the first elastic arm 111, the width of the second trunk 122 is greater than the width of the second elastic arm 121, and the width of the third trunk 132 is greater than the width of the third elastic arm 131 The width.

It can be seen from FIG. 3 that the first contact portion 114, the second contact portion 124, and the third contact portion 134 are misaligned with each other in the front and rear (or third axial direction). Wherein, the aforementioned first axis, second axis, and third axis are perpendicular to each other.

The fourth terminal 21 includes a fourth elastic arm 211, a fourth body 212 connected to the fourth elastic arm 211, and a fourth pin 213 connected to the fourth body 212. Specifically, as shown in FIG. 2, the fourth body 212 located on the uppermost side of the lower terminal assembly is connected between the fourth elastic arm 211 and the fourth pin 213, and the fourth elastic arm 211 is connected to the fourth body 212 On the right side of one end, the fourth pin 213 is connected to the other end of the fourth body 212. The number of pins is usually multiple, and in the embodiment of the present creation, the number of the fourth pins 213 is three. However, this creation is not limited to the above-mentioned examples.

The fifth terminal 22 includes a fifth elastic arm 221 and a fifth body 222. Specifically, as shown in FIG. 2, the fifth elastic arm 221 is connected to the middle of one end of the fifth body 222. In addition, as shown in FIG. 1, the fifth terminal 22 has no pins.

The sixth terminal 23 includes a sixth elastic arm 231, a sixth body 232 connected to the sixth elastic arm 231, and a sixth pin 233 connected to the sixth body 232. Specifically, as shown in FIG. 2, the sixth body 232 located at the lowermost side of the lower terminal assembly is connected between the sixth elastic arm 231 and the sixth pin 233, and the sixth elastic arm 231 is connected to the sixth body On the left side of one end of 232, the sixth pin 233 is connected to the other end of the sixth body 232. The number of pins is usually multiple, and in the embodiment of this creation, the number of the sixth pins 233 is 3, and the fourth pin 213 and the sixth pin 233 are arranged side by side. However, this creation is not limited to the above-mentioned examples.

It can be seen from the above that the fourth elastic arm 211, the fifth elastic arm 221, and the sixth elastic arm 231 are misaligned with each other on the left and right (the first axis), and the fourth body 212, the fifth body 222, and the sixth body 232 are up and down. (The second axis) is in upper contact and overlaps. Furthermore, the width of the fourth trunk 212 is greater than the width of the fourth elastic arm 211, the width of the fifth trunk 222 is greater than the width of the fifth elastic arm 221, and the width of the sixth trunk 232 is greater than that of the sixth elastic arm 231. width. The above-mentioned trunk is generally flat.

Furthermore, the first elastic arm 111, the second elastic arm 121, the third elastic arm 131, the fourth elastic arm 211, the fifth elastic arm 221, and the sixth elastic arm 231 all have a curved portion extending in the direction of the insertion space bending.

Further referring to FIG. 4, the fourth elastic arm 211 has a fourth contact portion 214, the fifth elastic arm 221 has a fifth contact portion 224, and the sixth elastic arm 231 has a sixth contact portion 234. The above-mentioned contact portion is located in the reflexed area corresponding to the curved portion of the elastic arm. It can be seen from FIG. 3 that the fourth contact portion 214, the fifth contact portion 224 and the sixth contact portion 234 are misaligned in the front and rear (third axial direction).

In addition, the first contact portion 114 and the sixth contact portion 234 are vertically symmetrical, the second contact portion 124 and the fifth contact portion 224 are vertically symmetrical, and the third contact portion 134 and the fourth contact portion 214 are vertically symmetrical. Therefore, when the connector is plugged into the external electronic component, the connector can be electrically connected to the external electronic component through the up-and-down symmetrical contact portion in the terminal structure.

When the connector is plugged into the external electronic component, the elastic arm of the terminal structure makes electrical contact with the external electronic component. The second terminal 12 and the fifth terminal 22 have no pins. The current flowing in (or out of) from external electronic components is all connected to the first pin 113, the third pin 133, the fourth pin 213, and the sixth pin. 233 flows out (or flows in). Specifically, the current flowing through the first elastic arm 111, the second elastic arm 121, and the third elastic arm 131 simultaneously flows through the first pin 113 and the third pin 133; The current of the elastic arm 221 and the sixth elastic arm 231 flows through the fourth pin 213 and the sixth pin 233 at the same time. In addition, the elastic arm has elasticity, so when the connector is inserted into the external electronic component, the elastic arm will generate a positive force to ensure a stable connection between the connector and the external electronic component. The greater the positive force, the greater the force (plugging force) required for plugging and unplugging the connector and the mating component, and the more inconvenient it is for the user to use. With the dislocation of the contact part back and forth, the positive force can be prevented from being too concentrated, and the positive force can be dispersed and the insertion force can be reduced.

In addition, the first contact portion 114, the second contact portion 124, and the third contact portion 134 of the upper terminal assembly 1 may be on the same horizontal plane (or the same position in the second axial direction) or the contact portion may be located in front of and behind the elastic arm ( The position on the third axis determines the height of the horizontal (on the second axis) position. Specifically, when the position of the contact portion in the third axis is farther, the distance from the corresponding trunk (distance from the fulcrum) is greater, and the position of the contact portion in the second axis is lower. In this way, when the mating element enters the connector for insertion, the positive force exerted on the mating element by each elastic arm is close, and the contact impedance between each other is also close. Similarly, the fourth contact portion 214, the fifth contact portion 224, and the sixth contact portion 234 of the lower terminal assembly 2 can be on the same horizontal plane (or the same position in the second axial direction) or according to whether the contact portions are located before and after the elastic arm The position (on the third axis) determines the height of the horizontal (on the second axis) position.

The width of the trunk is greater than the width of the elastic arm and the arrangement of multiple trunks in contact can increase the cross-sectional area when current flows from the elastic arm to the trunk, and increase the current carrying capacity of the terminal structure. In addition, when the terminal structure is carrying current, the temperature rises due to the electrothermal effect. The temperature rise will accumulate as the current flows through the path, causing the body temperature of the terminal structure to be higher than the temperature of the elastic arm. In this creation, by designing the width of the trunk to be larger than the width of the elastic arm, the current contact area of the trunk is increased to improve its heat dissipation capacity and slow the cumulative effect of temperature rise, that is, to extend the time for the trunk to cause high temperature.

In this embodiment, the first pin 113, the third pin 133, the fourth pin 213, and the sixth pin 233 are all welded parts, that is, the terminal structure 100 connects the pins (first pin 113, The third pin 133, the fourth pin 213 and the sixth pin 233) are fixed on the circuit board (not shown) by welding. However, this creation is not limited to the above-mentioned examples.

[Second Embodiment]

5, the biggest difference between the second embodiment and the first embodiment is that the second terminal 12 further includes a second pin 123 connected to the second body 122, and the fifth terminal 22 further includes a The fifth pin 223 of the five trunk 222. The current flowing through the first elastic arm 111, the second elastic arm 121 and the third elastic arm 131 simultaneously flows through the first pin 113, the second pin 123 and the third pin 133, and flows through the fourth elastic arm 211, A current of the fifth elastic arm 221 and the sixth elastic arm 231 flows through the fourth pin 213, the fifth pin 223, and the sixth pin 233 at the same time.

It should be noted that the second body 122 of the second terminal 12 in the first embodiment and the fifth body 22 of the fifth terminal 22 have no connecting pins, while the second body of the second terminal 12 in the second embodiment The second body 122 has a second pin 123, and the fifth body 22 of the fifth terminal 22 has a fifth pin 223. The difference between the two embodiments (the middle terminal has no pins) enables the connector terminal structures of the two different implementation types to be applicable to circuit boards with different insertion areas. Taking the connector terminal structure of the second embodiment as an example, since it is necessary to provide pins (second pin 123 and fifth pin 223) at the intermediate terminal (second terminal 12 and fifth terminal 22), the upper and lower body The upper and lower pins (for example, the first pin 113 and the third pin 133 in the upper terminal assembly 1 and the fourth pin 213 and the sixth pin 233 in the lower terminal assembly 2) connected to the upper terminal assembly must have a curved structure Only by extending the pins can a fixed distance be maintained between the pins to avoid too close to cause the heat generated when plugged into the circuit board is too concentrated and difficult to dissipate.

In this embodiment, the second pin 123 is arranged side by side with the first pin 113 and the third pin 133, and the number of the second pin 123 is also three. The fifth pin 223 is arranged side by side with the fourth pin 213 and the sixth pin 233, and the number of the fifth pin 223 is also three. In addition, the distance between adjacent first pins 113 is greater than the thickness of the first terminal 11, the distance between adjacent second pins 123 is greater than the thickness of the second terminal 12, and the adjacent third pins 133 The distance between adjacent fourth pins 213 is greater than the thickness of the third terminal 13, the distance between adjacent fourth pins 213 is greater than the thickness of the fourth terminal 21, and the distance between adjacent fifth pins 223 is greater than that of the fifth terminal 22 Thickness, the distance between adjacent sixth pins 233 is greater than the thickness of the sixth terminal 23. The increase of the pins and the limitation of the spacing can disperse the terminal structure and insert the contact points of the circuit board, so that the hot spots caused by the circuit board during current transmission will not be too concentrated, and the heat transfer can be effectively improved. Specifically, both the first pin 113 and the third pin 133 have a curved portion to increase the distance between the first pin 113 and the second pin 123, and the third pin 133 and the second pin 123; the fourth pin 213 and the sixth pin 233 also have a curved part to increase the distance between the fourth pin 213 and the fifth pin 223, and the sixth pin 233 and the fifth pin The distance between pins 223. Furthermore, in the aforementioned first embodiment of the present invention and other embodiments shown in the following, the structural design of the pins has the limitation of the pitch, and will not be repeated.

In this embodiment, the pins (first pin 113, second pin 123, third pin 133, fourth pin 213, fifth pin 223, and sixth pin 233) are all crimping parts (press-fi pin). Further referring to Figure 6, the crimping element refers to the design of the pin with a fish-eye hole structure (the first pin 113 in Figure 6), which can cause the pin to be deformed during the crimping process, thereby connecting the pin. The feet are tightly connected to the crimping holes of the PCB circuit board.

It should be noted that although the pins of the first embodiment are designed with welding parts, the pins of the second embodiment are designed with crimping parts. However, the above-mentioned example is only one of the feasible embodiments and is not intended to limit the present invention. In other words, the pins of the first embodiment can be designed with crimping parts, while the pins of the second embodiment are designed with welding parts. Furthermore, in the following embodiments of the present creation, the structural design of the pins can be welded parts or crimped parts, which will not be repeated.

[Third Embodiment]

The number of elastic arms 221 is two, and the number of sixth elastic arms 231 is two.

In addition, the width of the elastic arm in the first embodiment is substantially greater than that in the second embodiment, that is to say, the number of elastic arms in the third embodiment becomes larger and the width becomes narrower. The structural design with more elastic arms and narrower width can also effectively disperse the positive force, thereby achieving the effect of reducing the insertion and extraction force.

[Fourth Embodiment]

Refer to FIG. 8, which only shows a perspective view of the lower terminal assembly. The biggest difference between the fourth embodiment and the third embodiment is that the second terminal 12 further includes a second pin 123 connected to the second body 122, and the fifth terminal 22 further includes a second pin 123 connected to the fifth body 222.
