FIELD

The present invention relates to an electrical connector, and particularly to an electrical connector with terminals clamping solders.

BACKGROUND

The background description provided herein is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.

The Chinese Patent Application No. CN201720041445.3 discloses an electrical connector, which includes an insulating body and a plurality of terminals. The insulating body includes a plurality of accommodating holes accommodating the terminals. Each terminal is provided with a connecting portion, and the insulating body is provided with a protruding block. The protruding block and the connecting portion are located respectively at two opposite sides of a solder ball, and the protruding block and the connecting portion collectively clamp the solder ball.

However, in the electrical connector, the abutting directions of the connecting portions of all terminals to the solder balls are identical, and each protruding block only abuts against a corresponding solder ball. Due to the protruding blocks occupying the space of the electrical connector, it inevitably prevents the quantity of the terminals in the electrical connector from further increasing, which does not match with the trend of densification of the electrical connector. In addition, the abutting directions of the connecting portions of all terminals to the solder balls are identical, such that the abutting forces exerted by all terminals on the solder balls are concentrated in one direction, and the forces exerted by the terminals on the plastic for maintaining balance are also concentrated in one direction, which easily results in adverse effects such as warping of the insulating body, thus affecting the soldering of the terminals.

Therefore, a heretofore unaddressed need to design a new electrical connector exists in the art to address the aforementioned deficiencies and inadequacies.

SUMMARY

The present invention is directed to an electrical connector, in which the quantity of the abutting portion is reduced by using one abutting portion to abut against two solders, thereby providing more terminals.

A horizontal direction and the vertical direction are perpendicular to each other.

As shown in FIG. 1 and FIG. 2, the present invention provides an electrical connector, which includes an insulating body 1, a first terminal 2, a second terminal 3, a third terminal 4 and solders fixedly provided in the terminals. Specifically, the first terminal 2 and the second terminal 3 are signal terminals, and the third terminal 4 is a ground terminal. In other embodiments, the first terminal 2 and/or the second terminal 3 may be ground terminals, and the third terminal 4 may be a signal terminal.

The insulating body 1 includes a bottom wall 12 and a plurality of accommodating slots 11 running through the bottom wall 12 along the vertical direction. The accommodating slots 11 includes a first accommodating slot, a second accommodating slot and a third accommodating slot, the first terminal 2 is accommodated in the first accommodating slot, the second terminal 3 is accommodated in the second accommodating slot, the third terminal 4 is accommodated in the third accommodating slot, and the bottom wall is provided with a plurality of abutting portions protruding downward. Specifically, the abutting portions include a first abutting portion 121 and a second abutting portion 122, and the solders include a first solder 51, a second solder 52, a third solder 53 and a fourth solder 54. The first abutting portion 121 is located between the first solder 51 and the second solder 52, and the second abutting portion 122 is located between the third solder 53 and the fourth solder 54.

As shown in FIG. 2 and FIG. 3, the first terminal 2 has a first abutting arm 23, and the second terminal 3 has a second abutting arm 33. The first abutting portion 121 is located between the first abutting arm 23 and the second abutting arm 33, and the first abutting portion 121 is provided with a first abutting region 1211 and a second abutting region 1212 opposite to each other in the horizontal direction. In the present embodiment, the first abutting region 1211 and the second abutting region 1212 are two surfaces of the first abutting portion 121. In other embodiments, the first abutting region 1211 and the second abutting region 1212 may be two vertices of the first abutting portion 121. The first abutting arm 23 and the first abutting region 1211 clamp a first solder 51. The first abutting arm 23 exerts a first acting force F1 directed toward the first abutting portion 121 on the first solder 51, and the first acting force F1 has a lateral component in a leftward direction. The second abutting arm 33 and the second abutting region 1212 clamp a second solder 52. The second abutting arm 33 exerts a second acting force F2 directed toward the first abutting portion 121 on the second solder 52, and the second acting force F2 has a lateral component in a rightward direction. The first solder 51, the second solder 52 and the third solder 53 are solder balls. In other embodiments, the solders may be any material manufactured in any fixed shape that may solder the terminals onto a circuit board.

As shown in FIG. 4, FIG. 5 and FIG. 6, the first terminal 2 has a first body portion 21 accommodated in a corresponding accommodating slot 11 and a first extending portion 22 formed by extending downward from the first body portion 21. The first body portion 21 includes a first protruding portion 211 extending toward the second terminal 3 and another protruding portion extending away from the second terminal 3. Specifically, the first protruding portion 211 is a short protruding portion, and the other protruding portion is a long protruding portion 212. Along the left-right direction, a length of the long protruding portion 212 protruding from the first extending portion 22 is greater than a length of the short protruding portion 211 protruding from the first extending portion 22. The long protruding portion 212 and the first abutting arm 23 are located at a same side of the first extending portion 22, and the first protruding portion 211 and the long protruding portion 212 abut against a slot wall of the corresponding accommodating slot 11, such that the first body portion 21 is fixed in the corresponding accommodating slot 11. The first extending portion 22 passes beyond the bottom wall 12. The first extending portion 22 has a first bending portion 221 bending backward and a first straight portion 222 extending downward from the first bending portion 221. The first bending portion 221 abuts against the first solder 51 and stops the first solder 51 from moving upward.

The first straight portion 222 has a first side edge 2221 close toward the second terminal 3 and a second side edge 2222 away from the second terminal 3. The first abutting arm 23 includes a first elastic abutting portion 231 and a second elastic abutting portion 232 bending and extending from the first elastic abutting portion 231. The first clastic abutting portion 231 bends and extends from the second side edge 2222. The first solder 51 is located in a space enclosed by the first straight portion 222, the first elastic abutting portion 231, the second elastic abutting portion 232 and the first abutting region 1211, and the first straight portion 222, the first elastic abutting portion 231, the second clastic abutting portion 232 and the first abutting region 1211 collectively abut against the first solder 51. A bottom portion of the first straight portion 222 is provided with a notch 2223 at a location close to the first solder 51, and when soldering, the notch 2223 may absorb additional solder to prevent the solder from spreading. The first terminal 2 has a groove 24 at a location of the first bending portion 221. The groove 24 is located between the long protruding portion 212 and the first abutting arm 231, and the groove 24 separates the first body portion 21 and the first abutting arm 231 in the vertical direction. With the existence of the groove 24, a width of the first bending portion 221 in the left-right direction is less than a width of the first straight portion 222 in the left-right direction. In other words, in the left-right direction, the second side edge 2222 passes beyond the first bending portion 221. During elastic deformation, the first abutting arm 23 may utilize the elasticity of a portion of the first straight portion 222 to enhance its abutting force on the first solder 51. Meanwhile, the groove 24 may absorb the solder climbing upward, thus preventing the solder from spreading upward to the first body portion 21.

A tail end of the second elastic abutting portion 232 has a narrow portion 2321. The narrow portion 2321 inclines toward the first extending portion 22. A width of the narrow portion 2321 in the vertical direction is less than a width of the first elastic abutting portion 231 in the vertical direction. When mounting the first solder 51, the narrow portion 2321 abuts against the first solder 51 and may and pierce an oxidation layer on the surface of the first solder 51, which is convenient for subsequent soldering.

The second terminal 3 has a second body portion 31 accommodated in a corresponding accommodating slot 11 and a second extending portion 32 formed by extending downward from the second body portion 31. The second body portion 31 includes a second protruding portion 311 extending toward the first terminal 2, and the second protruding portion 311 abuts against a slot wall of the corresponding accommodating slot 11, such that the second body portion 31 is fixed in the corresponding accommodating slot 11. The second extending portion 32 passes beyond the bottom wall 12. The second extending portion 32 has a second bending portion 321 bending backward and a second straight portion 322 extending downward from the second bending portion 321. The second bending portion 321 is located above the second solder 52 and abuts against the second solder 52.

The second straight portion 322 has a third side edge 3221 close toward the first terminal 2 and a fourth side edge 3222 away from the first terminal 2. The second abutting arm 33 includes a third elastic abutting portion 331 and a fourth elastic abutting portion 332 bending and extending from the third elastic abutting portion 331. The third elastic abutting portion 331 bends and extends from the fourth side edge 3222. The second solder 52 is located in a space enclosed by the second straight portion 322, the third elastic abutting portion 331, the fourth elastic abutting portion 332 and the second abutting region 1212, and the second straight portion 322, the third elastic abutting portion 331, the fourth elastic abutting portion 332 and the second abutting region 1212 collectively abut against the second solder 52. A bottom portion of the second straight portion 322 is provided with a notch 3223 at a location close to the second solder 52, and when soldering, the notch 3223 may absorb additional solder to prevent the solder from spreading.

As shown in FIG. 3, the second elastic abutting portion 232 and the fourth elastic abutting portion 332 extend toward each other, and a distance D1 between a tail end of the second elastic abutting portion 232 and a tail end of the fourth elastic abutting portion 332 is shorter than a distance D2 between the fourth side edge 3222 and the second side edge 2222, such that a projection of the second elastic abutting portion 232 in the front-rear direction partially overlaps with the first extending portion 22, and a projection of the fourth elastic abutting portion 332 in the front-rear direction partially overlaps with the second extending portion 32.

As shown in FIG. 4, in the process of the first bending portion 221 and the second bending portion 321 extending downward, the distance between the two gradually increases. At any location, a distance D4 between the first extending portion 22 and the second extending portion 32 is greater than a distance D3 between the first protruding portion 211 and the second protruding portion 311.

As shown in FIG. 3, FIG. 4 and FIG. 7, the third terminal 4 has a third body portion 41 accommodated in a corresponding accommodating slot 11 and a third extending portion 42 formed by extending downward from the third body portion 41. The third extending portion 42 passes beyond the bottom wall 12. The third extending portion 42 has a third bending portion 421 bending backward and a third straight portion 422 extending downward from the third bending portion 421. A first soldering arm 43 and a second soldering arm 44 respectively extend from a left side and a right side of the third straight portion 422. The second abutting portion 122 is located between the first soldering arm 43 and the second soldering arm 44. The second abutting portion 122 is provided with a third abutting region 1221 and a fourth abutting region 1222 opposite to each other in the horizontal direction. The first soldering arm 43 and the third abutting region 1221 clamp a third solder 53, and the first soldering arm 43 exerts a third acting force F3 directed toward the second abutting portion 122 on the third solder 53. The second soldering arm 44 and the fourth abutting region 1222 clamp a fourth solder 54, and the second soldering arm 44 exerts a fourth acting force F4 directed toward the second abutting portion 122 on the fourth solder 54.

The first soldering arm 43 includes a first elastic soldering portion 431 and a second elastic soldering portion 432 bending and extending from the first elastic soldering portion 431. The first elastic soldering portion 431 bends and extends from one side edge of the third extending portion 42. The third extending portion 42, the first elastic soldering portion 431, the second elastic soldering portion 432 and the third abutting region 1221 collectively abut against the third solder 53. The second soldering arm 44 includes a third elastic soldering portion 441 and a fourth elastic soldering portion 442 bending and extending from the third elastic soldering portion 441. The third elastic soldering portion 441 bends and extends from another side edge of the third extending portion 42. The second elastic soldering portion 432 and the fourth elastic soldering portion 442 extend toward each other. The third extending portion 42, the third elastic soldering portion 441, the fourth elastic soldering portion 442 and the fourth abutting region 1222 collectively abut against the fourth solder 54.

The first terminal 2, the second terminal 3 and the third terminal 4 are arranged in a row in the left-right direction. The first soldering arm 43 and the second abutting arm 33 are adjacent to each other in the left-right direction, and directions of lateral components of the third acting force F3 and the second acting force F2 in the left-right direction are opposite to each other. Specifically, in the left-right direction, the direction of the lateral component of the third acting force F3 is leftward, and the direction of the lateral component of the second acting force F2 is rightward. It should be noted that the first terminal 2 and the second terminal 3 may be interchangeable. That is, the first soldering arm 43 may be adjacent to the first abutting arm 23 in the left-right direction, and directions of lateral components of the third acting force F3 and the first acting force F1 may be opposite to each other.

In sum, the electrical connector according to certain embodiments of the present invention has the following beneficial effects:

1. The first abutting region 1211 abuts against a first solder 51, and the second abutting region 1212 abuts against a second solder 52, such that one abutting portion may abut against two solders, which may reduce the provision of the abutting portion, and provide more terminals in a limited space, thus facilitating the densification trend of the connector.

The first abutting arm 23 may exert a first acting force F1 directed toward the first abutting portion 121 on the first solder 51, and the second abutting arm 33 may exert a second acting force F2 directed toward the first abutting portion 121 on the second solder 52. Because the first abutting portion 121 is located between the first abutting arm 23 and the second abutting arm 33, the first acting force F1 and the second acting force F2 will eventually act on the first abutting portion 121, and the lateral components of them along the left-right direction will be opposite to each other, thereby balancing the lateral components of the first acting force F1 and the second acting force F2 at the location of the first abutting portion 121. That is, in the left-right direction, the first acting force F1 has a lateral component in a leftward direction, the second acting force F2 has a lateral component in a rightward direction, and the two lateral components are eventually balanced at the first abutting portion. Thus, the force received by the insulating body 1 from the terminals do not concentrate in the same direction, thereby allowing the insulating body 1 not to easily warp, such that the soldering of the first terminal 2 and the second terminal 3 are more stable.

2. The first extending portion 22 passes beyond the bottom wall 12, such that the first abutting arm 23 also passes beyond the bottom wall 12. In this case, the first abutting arm 23 is located outside the corresponding accommodating slot 11, and its size is not limited by the corresponding accommodating slot 11. When the solder is mounted, the first abutting arm 23 has sufficient space for deformation, and even if the solder has a volume change due to manufacturing tolerance, it may be normally clamped by the first abutting arm 23 and the first abutting portion 121. On the other hand, the first extending portion 22, the first elastic abutting portion 231, the second elastic abutting portion 232 and the first abutting region 1211 collectively abut against the first solder 51, such that the first solder 51 may be stably clamped between the first terminal 2 and the first abutting portion 121 without easily detaching therefrom.

3. The distance between the tail end of the second elastic abutting portion 232 and the tail end of the fourth elastic abutting portion 332 is shorter than the distance between the fourth side edge 3222 and the second side edge 2222, allowing a projection of the second elastic abutting portion 232 in the front-rear direction to partially overlap with the first extending portion 22, and a projection of the fourth elastic abutting portion 332 in the front-rear direction to partially overlap with the second extending portion 32, and the widths of the terminals do not significantly change, thereby enabling more terminals to be provided in the left-right direction, thus facilitating densification of the electrical connector.

4. The first bending portion 221 stops the first solder 51 from moving upward, such that the first solder 51 may be more stably fixed on the first terminal 2. Further, when the first terminal 2 is soldered on a circuit board, the first solder 51 melts and fills in the space between the first bending portion 221 and the first straight portion 222, and the signal may be transmitted to the circuit board through a path formed by the solder, without passing the first bending portion 221 with a longer path, thereby reducing the distance of the transmission of the signal in the first terminal 2, and improving high frequency performance.

5. The first protruding portion 211 and the second protruding portion 311 respectively abut against the slot walls of the corresponding accommodating slots 11, such that the first terminal 2 and the second terminal 3 may be fixed in the corresponding accommodating slots 11. However, the first protruding portion 211 and the second protruding portion 311 are close to each other, which results in the coupling strength between the first terminal 2 and the second terminal 3 to become higher, and there may be an insertion loss drop in the high frequency band. The distance between the first extending portion 22 and the second extending portion 32 is greater than the distance between the first protruding portion 211 and the second protruding portion 311, which may reduce the coupling strength between the first terminal 2 and the second terminal 3, thus reducing the insertion loss drop in the high frequency band.
