Description

Technical Field

[0001] This invention relates to an electrical connector, and more particularly to an electrical connector for electrically connecting an electronic component and a circuit board. Background Technology

[0002] A conventional electrical connector, such as Chinese Patent CN200620060962.7, includes an insulating body for accommodating a chip, a plurality of conductive terminals, and a cover over the chip. The conductive terminals are housed within the insulating body. The cover has pressing arms corresponding to the terminals on the chip. The cover is rotatable around the insulating body via a pivot. The pivot is fixed in position and located on the side of the pressing arms furthest from the chip. The pivot is connected to the pressing arms. When the cover is opened, the chip can be installed into or removed from the insulating body. When the cover is closed, the chip can be held within the insulating body, and the terminals on the chip can be electrically connected to the conductive terminals via the pressing arms.

[0003] When the cover is rotated and fastened to the chip, the user applies a fastening force to a pressing position on the cover. The pressing arm presses the terminals on the chip, and the pressed portion of the terminals on the chip provides a reaction force to the pressing arm. With the axis of the rotating shaft as the fulcrum, the lever arm of the fastening force is the distance between the pressing position and the fulcrum, while the lever arm of the reaction force is the distance between the fulcrum and the pressed portion of the terminal.

[0004] The inventors of this invention discovered that, since the pivot determines the position of the cover after it is opened, in order for the chip to be smoothly installed or removed after the cover is opened, the axis of the pivot of the aforementioned electrical connector is located away from the terminals on the chip. This allows the pressing arm to also be located away from the terminals on the chip after the cover is opened, providing sufficient space for installing or removing the chip. However, when the cover is closed, the pivot's distance from the chip's terminals results in a longer lever arm for the reaction force. According to the lever principle, the aforementioned electrical connector requires a larger closing force, making it more difficult for the user to close the cover.

[0005] Therefore, it is necessary to design a new electrical connector to overcome the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an electrical connector in which, when the first cover (or the first crimping member) is in the open position, the axis of the first rotating shaft is located in a first position that is relatively far away from the electronic component, and when the first cover (or the first crimping member) is in the closed position, the axis of the first rotating shaft is located in a second position that is relatively close to the electronic component. This not only facilitates the installation or removal of the electronic component, but also reduces the force applied by the user when operating the first cover (or the first crimping member), thus achieving a labor-saving effect.

[0007] To achieve the above objectives, the present invention provides the following first technical solution:

[0010] Furthermore, the electrical connector also includes a plurality of second terminals fixed to the base and electrically connected to the second pin of the chip. The second cover also has at least one second crimping arm connected to the second rotating shaft. When the second cover is in the open position, the projection of the second crimping arm is offset from the projection of the second pin when viewed along the first direction. When both the first cover and the second cover are in their respective closed positions, the first cover covers a portion of the second cover along the first direction to restrict the movement of the second cover. The distance between the third position and the second pin in the second direction is greater than the distance between the second position and the first pin in the second direction. When viewed along the first direction, the projection of the second crimping arm overlaps with the projection of the second pin. The second crimping arm presses against the second pin along the first direction, and the second terminal is electrically in contact with the second pin.

[0011] Furthermore, the first pivot portion is provided with a first receiving space for accommodating the first rotating shaft, and the second pivot portion is provided with a second receiving space for accommodating the second rotating shaft. The dimension of the first receiving space along the second direction is larger than the dimension of the second receiving space along the second direction.

[0012] Furthermore, the electrical connector also includes a plurality of second terminals fixed to the base and used for electrical connection with the second pin of the chip. The second cover also has at least one second crimping arm connected to the second rotating shaft. When the second cover is in the open position, the axis of the second rotating shaft is in the fourth position, and when viewed along the first direction, the projection of the second crimping arm is offset from the projection of the second pin.

When the first cover and the second cover are both in the corresponding closed position, the relief groove receives the second main body, the recess receives the stepped portion, and the groove wall of the recess covers the stepped portion along the first direction.

[0015] Compared with the prior art, the first technical solution of the present invention has the following beneficial effects: By designing the axis of the first rotating shaft to be variable, when the first cover is in the open position, the first position is farther away from the first guide portion, so that the first pressing arm is also farther away from the first guide portion under the drive of the first rotating shaft, allowing the first pressing arm to yield to the first guide portion, facilitating the smooth removal or installation of the electronic component; when the first cover is in the closed position, the second position is closer to the second guide portion, which can shorten the distance between the pressing position between the first pressing arm and the first guide portion and the axis of the first rotating shaft, and according to the lever principle, can reduce the force applied by the user when operating the first cover to close. Therefore, the electrical connector of the first technical solution of the present invention can achieve a labor-saving effect without hindering the installation or removal of the electronic component.

[0016] To achieve the above objectives, the present invention also provides the following second technical solution:

[0017] An electrical connector, characterized by: a base having a mounting groove recessed along a first direction and a first pivot portion located on one side of the mounting groove along a second direction, the first direction being perpendicular to the second direction; a plurality of first terminals fixed to the base, each first terminal having a first abutting portion exposed along the first direction; and a first cover having a first body, at least one first crimping arm extending from the first body, and a first rotating shaft connected to the first crimping arm, the first rotating shaft being mounted to the first pivot portion, the first body having a pressing portion, and the first cover being oriented around the first rotating shaft. The base moves between an open position and a closed position; wherein, when the first cover is in the open position, the axis of the first rotating shaft is in a first position, and when viewed along the first direction, the projection of the first abutment and the projection of the first pressing arm are offset; when the first cover is in the closed position, the axis of the first rotating shaft is in a second position, the second position is closer to the first abutment relative to the first position along the second direction, and there is a first receiving portion between the first abutment and the first pressing arm, and when viewed along the first direction, the projection of the first abutment and the projection of the first pressing arm overlap.

[0018] Furthermore, the base also includes a second pivot portion located on the other side of the mounting groove along the second direction. The electrical connector also includes a plurality of second terminals fixed to the base and a second cover. The second terminals have a second abutment portion exposed on the base along the first direction. The second cover has a second body, at least one second crimping arm extending from the second body, and a second rotating shaft connected to the second crimping arm. The second rotating shaft is mounted on the second pivot portion. The second cover moves relative to the base between an open position and a closed position about the second rotating shaft. When the second cover is in the open position, the axis of the second rotating shaft is in a third position, and when viewed along the first direction, the projection of the second abutment portion and the projection of the second crimping arm are offset. When the second cover is in the closed position, the axis of the second rotating shaft is in the third position, and a second receiving portion is provided between the second abutment portion and the second crimping arm. When viewed along the first direction, the projection of the second abutment portion and the projection of the second crimping arm overlap.

[0019] Furthermore, the base also includes a second pivot portion located on the other side of the mounting groove along the second direction, and the electrical connector also includes a plurality of second terminals fixed to the base and a second cover. The second terminals have a second abutment portion exposed on the base along the first direction. The second cover has a second body, at least one second crimping arm extending from the second body, and a second rotating shaft connected to the second crimping arm. The second rotating shaft is mounted on the second pivot portion, and the second cover moves relative to the base between an open position and a closed position about the second rotating shaft.

[0020] When the second cover is in the open position, the axis of the second rotating shaft is in the fourth position, and when viewed along the first direction, the projection of the second abutment and the projection of the second pressing arm are offset; when the second cover is in the closed position, the axis of the second rotating shaft is in the fifth position, the fifth position is closer to the second abutment than the fourth position along the second direction, and there is a second receiving portion between the second abutment and the second pressing arm, and when viewed along the first direction, the projection of the second abutment and the projection of the second pressing arm overlap.

[0021] Furthermore, the first body is provided with a clearance groove and a recess communicating with the clearance groove. The electrical connector also includes a second cover, the second cover including a second pivot, a second body for covering the mounting groove, and a stepped portion extending from the second body.

When both the first cover and the second cover are in the corresponding closed position, the clearance groove receives and exposes the second body, the recess receives the stepped portion, and the groove wall of the recess covers the stepped portion along the first direction.

[0022] Furthermore, the first terminal also has a tail extending from the first abutting portion in a direction away from the mounting groove, and the first crimping arm is provided with a clearance groove; wherein, when the first cover is in the open position, the clearance groove yields to the tail, and the groove surface of the clearance groove and the tail mutually limit each other.

[0025] Compared with the prior art, the second technical solution of the present invention has the following beneficial effects: By designing the axis of the first rotating shaft to be variable, when the first cover is in the open position, the first position is farther away from the first abutment portion, so that the first pressing arm is also farther away from the first abutment portion under the drive of the first rotating shaft. This allows the first pressing arm to make way for the electronic component when a part of the electronic component is located in the first receiving portion, facilitating the smooth removal or installation of the electronic component. When the first cover is in the closed position, the second position is closer to the first guide portion. Therefore, when a part of the electronic component is located in the first receiving portion, the distance between the abutment position of the first pressing arm and the part of the electronic component and the axis of the first rotating shaft can be shortened. Based on the lever principle, this reduces the force applied by the user when closing the first cover.

[0028] Furthermore, the electrical connector also includes a second crimping member and a plurality of second terminals fixed to the base.

When both the first and second crimping members are in their respective closed positions, the first and second crimping members cover the mounting slot, and the second crimping arm presses against the second conductive portion, with the second terminals making electrical contact with the second conductive portion.

[0029] Furthermore, the recessed direction of the mounting groove is defined as the first direction, and the first rotating shaft and the second rotating shaft are located on opposite sides of the mounting groove along a second direction perpendicular to the first direction; wherein, when the second pressing member is in the open position and in the closed position, the axis of the second rotating shaft is in the third position, and the distance between the third position and the second guide portion in the second direction is greater than the distance between the second position and the first guide portion in the second direction; and when the first pressing member and the second pressing member are both in the corresponding closed position, the first pressing member covers a part of the second pressing member to restrict the movement of the second pressing member.

Detailed Implementation Methods

[0054] To facilitate a better understanding of the purpose, structure, features, and effects of this invention, the invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0055] To facilitate a better understanding of the technical solution of the present invention, the Z-axis in the three-dimensional coordinate axes in the accompanying drawings is defined as the first direction, the X-axis as the second direction, and the Y-axis as the third direction, wherein the X-axis, Y-axis and Z-axis are mutually perpendicular to each other.

[0056] like Figures 1 to 11 As shown, an electrical connector 100 according to a first embodiment of the present invention is used for electrically connecting an electronic component 200. The electrical connector 100 includes a base 1, a plurality of terminals fixed to the base 1, a first crimping member 2, and a second crimping member 3. The first crimping member 2 and the second crimping member 3 are respectively movably connected to the base 1. The electronic component 200 is mounted on the base 1 and has a plurality of conductive portions electrically connected to the terminals. The electrical connector 100 is mounted to a circuit board and electrically connected to the circuit board through the terminals. In this embodiment, the electronic component 200 is a chip, and the plurality of conductive portions are the plurality of pins of the chip; in other embodiments, the electronic component 200 may be other required electronic components 200.

[0057] Please see Figure 1 and Figure 11 The base 1 has a first pivot portion 15, a second pivot portion 16, and a mounting groove 14. The mounting groove 14 is recessed along a first direction Z and is used for mounting the electronic component 200 along the first direction Z. The first pivot portion 15 and the second pivot portion 16 are disposed opposite each other along a second direction X, and the mounting groove 14 is located between the first pivot portion 15 and the second pivot portion 16 along the second direction X. In a first embodiment, the first pivot portion 15 extends outward from one side of the base 1 along the second direction X and has a first receiving space 151; the second pivot portion 16 extends outward from the other side of the base 1 along the second direction X and has a second receiving space 161.

[0058] Please see Figure 1 , Figure 4 and Figure 10The plurality of terminals include a plurality of first terminals 4 and a plurality of second terminals 5. The plurality of first terminals 4 are arranged in a row along a third direction Y, and the plurality of second terminals 5 are arranged in a row along the third direction Y. The base 1 is provided with a plurality of channels, including a first channel 11 and a second channel 12. Each first channel 11 houses a corresponding first terminal 4, and each second channel 12 houses a corresponding second terminal 5. The plurality of conductive portions of the electronic component 200 include a plurality of first conductive portions 201 (in the first embodiment, the first conductive portion 201 is the first pin of the chip) and a plurality of second conductive portions 202 (in the first embodiment, the second conductive portion 202 is the second pin of the chip). Each first terminal 4 is used to electrically connect to the corresponding first conductive portion 201, and each second terminal 5 is used to electrically connect to the corresponding second conductive portion 202.

[0059] The first terminal 4 has a first abutting portion 41 exposed along the first direction Z of the base 1 and a first tail portion 42 extending from the first abutting portion 41 in a direction away from the mounting groove 14. The first abutting portion 41 abuts against the first conductive portion 201 (i.e., the first pin of the first embodiment). The second terminal 5 has a second abutting portion 51 exposed along the first direction Z of the base 1 and a second tail portion 52 extending from the second abutting portion 51 in a direction away from the mounting groove 14. The second abutting portion 51 abuts against the second conductive portion 202 (i.e., the second pin of the first embodiment).

[0060] Please see Figures 1 to 9The first crimping member 2 has a first pivot 23 mounted on the first pivot portion 15, a plurality of first crimping arms 22 connected to the first pivot 23, a first body 21 for covering the mounting groove 14, and two fastening portions 27 extending from the first body 21, the two fastening portions 27 being arranged opposite each other along the third direction Y. The first crimping member 2 moves about the first pivot 23 relative to the base 1 between an open position and a closed position, and the fastening portions 27 are used to engage with the base 1. The second crimping member 3 has a second pivot 33 mounted on the second pivot portion 16, at least one second crimping arm 32 connected to the second pivot 33, and a second body 31 for covering the mounting groove 14. The second crimping member 3 moves about the second pivot 33 relative to the base 1 between an open position and a closed position. The first body 21 has a pressing portion 28 for the user to operate the first crimping member 2. When both the first crimping member 2 and the second crimping member 3 are in their respective open positions, the user can install the electronic component 200 into or remove it from the mounting slot 14. When both the first crimping member 2 and the second crimping member 3 are in their respective closed positions, the electronic component 200 can be held within the mounting slot 14 so that the electronic component 200 contacts the terminal. It should be noted that in the first embodiment, the pressing part 28 is only provided on the first crimping member 2. In other embodiments, the second crimping member 3 may be provided with a corresponding pressing part 28 as needed. In addition, the number and position of the fastening parts 27 of the first crimping member 2 may also be adjusted as needed, and are not limited here.

[0061] It should be noted that, in the first embodiment, the first pressing member 2 pivots about the first rotating shaft 23 relative to the base 1 between the open position and the closed position.

[0062] Please see Figure 1 , Figure 3 , Figure 9The first body 21 is provided with a relief groove 25 and a recess 26 communicating with the relief groove 25. The second pressing member 3 also has a stepped portion 34 extending from the second body 31. When the first pressing member 2 and the second pressing member 3 are both in their corresponding closed positions, the relief groove 25 receives the second body 31, the recess 26 receives the stepped portion 34, and the groove wall of the recess 26 covers the stepped portion 34 along the first direction Z. Specifically, in the first embodiment, the first body 21 has a first surface 211 facing the mounting groove 14 and a second surface 212 opposite to the first surface 211. The relief groove 25 penetrates the first surface 211 and the second surface 212, and the recess 26 is recessed from the first surface 211 and does not penetrate the second surface 212. The present invention achieves the restriction of the movement of the second pressing member 3 by the cooperation between the groove 26 and the step portion 34. At the same time, the relief groove 25 accommodates the second body 31, allowing the first body 21 and the second body 31 to be staggered over a larger range in the second direction X, which is beneficial to the mutual restraint between the first pressing member 2 and the second pressing member 3, and both cover the mounting groove 14 in a larger area.

[0063] It should be noted that, in the first embodiment, the groove wall of the groove 26 covers and presses against the stepped portion 34 along the first direction Z to more effectively restrict the movement of the second pressing member 3; however, in other embodiments, the groove wall of the groove 26 may only cover the stepped portion 34 along the first direction Z without pressing against it. Furthermore, in the first embodiment, when the first body 21 and the second body 31 are in their corresponding closed positions, the first pressing member 2 and the second pressing member 3 cover and press against the electronic component 200, making the electrical contact between the electronic component 200 and the first terminal 4 and the second terminal 5 more stable; however, in other embodiments, the first body 21 and the second body 31 may only cover the mounting groove 14 without pressing against the electronic component 200.

[0064] Please see Figure 4 , Figure 5 and Figure 8When the first crimping member 2 is in the open position, the axis of the first rotating shaft 23 is in the first position A, and the first crimping arm 22 is positioned to allow the electronic component 200 to be installed in or removed from the mounting slot 14. It should be noted that, in the first embodiment, since the first crimping arm 22, the first guide portion 201, and the first abutting portion 41 abut against each other sequentially along the first direction Z, in order to allow the first crimping arm 22 to yield to the first guide portion 201, in the first embodiment, when viewed along the first direction Z, the projection of the first crimping arm 22 is offset from the projection of the first guide portion 201 (i.e., the first pin in the first embodiment). It can be understood that, since the first abutting portion 41 is used to abut against the first guide portion 201, in the first embodiment, when viewed along the first direction Z, the projection of the first abutting portion 41 is offset from the projection of the first crimping arm 22, that is, when the electronic component 200 is installed or removed along the first direction Z, the first crimping arm 22 will not block the first guide portion 201 in the first direction Z.

[0065] When the first crimping member 2 is in the closed position, the axis of the first rotating shaft 23 is in the second position B. The second position B is offset from the first position A toward the first guide portion 201. The first crimping arm 22 is used to press against the first guide portion 201, and the first terminal 4 is used to make electrical contact with the first guide portion 201. It should be noted that in the first embodiment, since the first conductive part 201 is located on one side of the first rotating shaft 23 along the second direction X, and the first crimping arm 22, the first conductive part 201 and the first abutting part 41 abut against each other in sequence along the first direction Z, in order to achieve the second position B offset relative to the first position A toward the first conductive part 201 and the first crimping arm 22 abutting against the first conductive part 201, the second position B in the first embodiment is closer to the first conductive part 201 along the second direction X relative to the first position A, and when viewed along the first direction Z, the projection of the first crimping arm 22 overlaps with the projection of the first conductive part 201. The first crimping arm 22 is used to abut against the first conductive part 201 along the first direction Z, and the first terminal 4 is in electrical contact with the first conductive part 201. Understandably, when the first crimping member 2 is in the closed position, the first guide portion 201 of the first embodiment will be located between the first abutment portion 41 and the first crimping arm 22. Therefore, there is a first receiving portion between the first abutment portion 41 and the first crimping arm 22, which is used to receive the first guide portion 201.

[0066] It should be noted that when the first crimping member 2 needs to be closed, the user applies force to the pressing part 28, causing the first crimping member 2 to gradually move from the open position to the closed position. The pressing position of the first crimping arm 22 of the first crimping member 2 will also gradually press against the first guide part 201. The first crimping member 2 will be subjected to the force F1 applied by the user and the reaction force F2 of the first guide part 201. With the axis of the first rotating shaft 23 as the fulcrum, the first lever arm L1 corresponding to the force F1 is from the pressing part 28 to the axis of the first rotating shaft 23, and the second lever arm L2 corresponding to the reaction force F2 is from the pressing position of the first crimping arm 22 to the axis of the first rotating shaft 23. After the first crimping arm 22 presses against the first guide part 201, the closer the first crimping member 2 is to the closed position, the greater the pressure exerted by the first crimping arm 22 on the first guide part 201, and the greater the corresponding reaction force F2. Therefore, the force F1 applied by the user must also be greater. At the instant that the closed position is about to be reached, the position of the axis of the first rotating shaft 23, the position of the pressing part 28, and the reaction force F2 can all be regarded as being consistent with the first pressing member 2 when it is in the closed position.

[0067] Therefore, by designing the axial position of the first rotating shaft 23 to be variable, when the first pressing member 2 is in the open position, the first position A is farther away from the first guide portion 201 or the first abutment portion 41, so that the first pressing arm 22 is also farther away from the first guide portion 201 or the first abutment portion 41 under the drive of the first rotating shaft 23, thereby realizing that the first pressing arm 22 yields to the first guide portion 201, so that the electronic component 200 can be smoothly installed or removed; at the same time, when the first pressing member 2 is in the closed position, the second position B is closer to the first guide portion 201 or the first abutment portion 41, so that the first pressing arm 22 is also closer to the first guide portion 201 under the drive of the first rotating shaft 23, thereby shortening the second lever arm L2. At the instant before reaching the closed position, the first lever arm L1 and the reaction force F2 of the electrical connector 100 are determined. According to the lever principle F1L1=F2L2, the present invention shortens the second lever arm L2, thereby reducing the force F1 and the amount of force applied by the user, achieving a labor-saving effect. In summary, the electrical connector 100 of the present invention can both prevent the first crimping member 2 from hindering the installation or removal of the electronic component 200 and reduce the force applied by the user. Especially in this embodiment, the first crimping member 2 also engages with the protrusion 13 of the base 1 through the fastening part 27. At the moment of fastening, the user not only needs to overcome the reaction force F2, but also the blocking force of the protrusion 13. The present invention reduces the force applied by the user, resulting in a more significant improvement in the user experience.

[0068] It should be noted that at the instant before the first crimping member 2 closes, the magnitude of the reaction force F2 depends on the contact relationship (material, size, relative position, etc.) between the first terminal 4, the electronic component 200, and the first crimping arm 22. Therefore, when the contact relationship between the three remains unchanged, the reaction force F2 at the instant of closure remains unchanged. Thus, reducing the length of the second lever arm L2 can reduce the force F1. That is, for an electrical connector 100 where the first lever arm L1 and the reaction force F2 are already determined, compared to before adopting the technical solution of this invention, adopting the solution of this invention can shorten the second lever arm L2, thereby reducing the force F1 applied by the user.

[0069] When the first crimping member 2 is in the open position, the clearance groove 24 is positioned to allow the first tail portion 42 to move excessively.

[0070] Please see Figure 9When both the first pressing member 2 and the second pressing member 3 are in their corresponding closed positions, the distance between the pressing part 28 along the second direction X and the axis of the first rotating shaft 23 is defined as the first distance D1, and the distance between the pressing part 28 along the second direction X and the axis of the second rotating shaft 33 is defined as the second distance D2. The first distance D1 is greater than the second distance D2. It can be understood that the first distance D1 can be considered as the length of the lever arm L1 of the force applied just before the first pressing member 2 closes. Compared to the first distance D1 being equal to or less than the second distance D2, this invention, by making the first distance D1 greater than the second distance D2, increases the first lever arm L1 of the force F1 according to the lever principle, which can further reduce the force F1, making it more labor-saving.

[0071] Please see Figure 4 , Figure 5 and Figure 8 In the first embodiment, when the second crimping member 3 is in the open position, the second crimping arm 32 yields to the second conductive portion 202 of the electronic component 200, so that the electronic component 200 can be installed in or removed from the mounting groove 14; when the first crimping member 2 and the second crimping member 3 are both in the corresponding closed position, the first crimping member 2 and the second crimping member 3 cover the mounting groove 14, and the second crimping arm 32 is used to press against the second conductive portion 202, and the second terminal 5 is used to make electrical contact with the second conductive portion 202. Similar to the first crimping member 2, in the first embodiment, when the second crimping member 3 is in the open position, when viewed along the first direction Z, the projection of the second crimping arm 32 is offset from the projection of the second guide portion 202 (the second pin in this embodiment); when the second crimping member 3 is in the closed position, when viewed along the first direction Z, the projection of the second crimping arm 32 overlaps with the projection of the second guide portion 202, the second crimping arm 32 presses against the second pin along the first direction Z, and the second terminal 5 is in electrical contact with the second pin.

[0072] Understandably, since the second abutment portion 51 of the second terminal 5 is used to abut against the second conductive portion 202, when the second crimping member 3 is in the open position, the projection of the second abutment portion 51 is offset from the projection of the second crimping portion 32; when the second crimping member 3 is in the closed position, looking along the first direction Z, the projection of the second crimping arm 32 overlaps with the projection of the second abutment portion 51 of the second terminal 5, and there is a second receiving portion between the second crimping arm 32 and the second abutment portion 51, which is used to receive the second conductive portion 202.

[0073] Please see Figure 5 , Figure 8 and Figure 11 In the first embodiment, when the second crimping member 3 is in the open position and the closed position, the axis of the second rotating shaft 33 is in the third position C. The distance between the third position C and the second guide portion 202 in the second direction X is greater than the distance between the second position B and the first guide portion 201 in the second direction X. When both the first crimping member 2 and the second crimping member 3 are in their respective closed positions, the first crimping member 2 covers a portion of the second crimping member 3 to restrict the movement of the second crimping member 3. Since the movement of the second crimping member 3 is restricted by the first crimping member 2, the second crimping member 3 does not need to be fastened to the base 1. The force applied by the user when closing the second crimping member 3 is relatively small, and the need for effort is small. Therefore, the axis of the second rotating shaft 33 is fixed, and the axis of the second rotating shaft 33 is maintained at the third position C, which is relatively far away from the second guide portion 202. This facilitates the smooth installation or removal of the electronic component 200 when the second crimping member 3 is in the open position. In the first embodiment, the first rotating shaft 23 is a cam rotating shaft, and the second rotating shaft 33 is a round shaft.

[0074] Furthermore, the first accommodating space 151 is used to accommodate the first rotating shaft 23, and the second accommodating space 161 is used to accommodate the second rotating shaft 33. The dimension of the first accommodating space 151 along the second direction X is larger than the dimension of the second accommodating space 161 along the second direction X. Thus, the larger size of the first accommodating space 151 provides movement space for the axis of the first rotating shaft 23; the smaller size of the second accommodating space 161 facilitates fixing the second rotating shaft 33, thereby fixing the axis position of the second rotating shaft 33.

[0075] like Figures 12 to 15The diagram shows an electrical connector 100 according to a second embodiment of the present invention. Similar to the first embodiment, in the second embodiment, when the second crimping member 3 is in the open position, the second crimping arm 32 yields to the second conductive portion 202 of the electronic component 200, allowing the electronic component 200 to be mounted in or removed from the mounting slot 14; when both the first crimping member 2 and the second crimping member 3 are in their respective closed positions, the first crimping member 2 and the second crimping member 3 cover the mounting slot 14, and the second crimping arm 32 presses against the second conductive portion 202, and the second terminal 5 makes electrical contact with the second conductive portion 202. More specifically, in order to allow the second crimping arm 32 to yield to or press against the second conductive portion 202, in the second embodiment, when the second crimping member 3 is in the open position, viewed along the first direction Z, the projection of the second crimping arm 32 is offset from the projection of the second conductive portion 202; when the second crimping member 3 is in the closed position, viewed along the first direction Z, the projection of the second crimping arm 32 overlaps with the projection of the second conductive portion 202, the second crimping arm 32 presses against the second conductive portion 202 along the first direction Z, and the second terminal 5 is in electrical contact with the second conductive portion 202.

[0076] Understandably, since the second abutment portion 51 of the second terminal 5 is used to abut against the second conductive portion 202, when the second crimping member 3 is in the open position, the projection of the second abutment portion 51 is offset from the projection of the second crimping arm 32; when the second crimping member 3 is in the closed position, viewed along the first direction Z, the projection of the second crimping arm 32 overlaps with the projection of the second abutment portion 51, and a second receiving portion is provided between the second crimping arm 32 and the second abutment portion 51. The second receiving portion is used to receive the second conductive portion 202.

[0077] The difference between the second embodiment and the first embodiment is that in the second embodiment, when the second pressing member 3 is in the open position, the axis of the second rotating shaft 33 is at the fourth position D; when the second pressing member 3 is in the closed position, the axis of the second rotating shaft 33 is at the fifth position E, and the fifth position E is offset relative to the fourth position D towards the second guide portion 202. Specifically, in the second embodiment, the second guide portion 202 is located on one side of the second rotating shaft 33 along the second direction X, and the fifth position E is closer to the second guide portion 202 along the second direction X relative to the fourth position D. It can be understood that in the second embodiment, since the second abutment portion 51 is used to abut against the second guide portion 202, the fifth position E is closer to the second abutment portion 51 along the second direction X relative to the fourth position D. In the second embodiment, the second pressing member 3 is also similar to the first pressing member 2, designed with a variable axis position for the second rotating shaft 33. Similarly, this makes the second pressing member 3 relatively easier to close, reducing the risk of the user applying too much force to the second pressing member 3 and causing it to break. In this embodiment, the first rotating shaft 23 is a cam rotating shaft, and the second rotating shaft 33 is also a cam rotating shaft. Furthermore, the second crimping arm 32 is also provided with a relief groove 24, which accommodates the second tail portion 52 of the second terminal 5 when the second crimping member 3 is in the closed position.

[0078] In addition, such as Figures 16 to 17 The diagram shows an electrical connector 100 according to a third embodiment of the present invention. In the first embodiment, the first crimping member 2 pivots relative to the base 1 about the first pivot 23 between an open position and a closed position. Since the first pivot 23 in the first embodiment is a cam pivot and the first receiving space 151 is used to accommodate the first pivot 23, while the first pivot 23' in the third embodiment is smaller in volume and has a different shape than the first pivot 23, the first receiving space 151 has sufficient space to provide the first pivot 23' with enough space to perform pivoting and other movements.

[0079] After the first crimping member 2 pivots relative to the base 1 between the open and closed positions around the first rotating shaft 23', the first crimping member 2 moves along one side of the second direction X. When the first crimping member 2 is in the closed position, in order to prevent the first crimping member 2 from moving along the other side of the second direction X, two fixing parts 29 are provided on the first crimping member 2 to fix it to the base 1.

[0080] Alternatively, the first pressing member 2 moves along one side of the second direction X, and then the first pressing member 2 pivots relative to the base 1 around the first rotating shaft 23' between the open and closed positions. When the first pressing member 2 is in the closed position, in order to prevent the first pressing member 2 from moving along the other side of the second direction X, two fixing parts 29 are provided on the first pressing member 2 to fix it to the base 1.

[0081] In the third embodiment, the volume of the first rotating shaft 23' is smaller than that of the first rotating shaft 23 in the first embodiment, and the first accommodating space 151 is the same. Therefore, the first rotating shaft 23' has more room to move, thereby reducing the manufacturing difficulty of the base 1 and the first pressing member 2 and improving production efficiency.

[0082] It should be noted that in the above three embodiments, the first pressing member 2 and the second pressing member 3, in addition to pressing against the first guide portion 201 and the second guide portion 202 respectively, also cover the mounting groove 14 to form a cover structure. Therefore, the first pressing member 2 can also be called the first cover, and the second pressing member 3 can also be called the second cover. In the above first and second embodiments, the first rotating shaft 23 is shown as a cam rotating shaft. In the third embodiment and other embodiments, the first rotating shaft 23' can also be other shapes.

[0083] In other embodiments, either the first crimping member 2 or the second crimping member 3 may not cover the mounting groove 14. Alternatively, in other embodiments, the first crimping member 2 (or the first cover) may be used to press against the first guide portion 201, without a second crimping member 3 (or the second cover) to press against the second guide portion 202, or a second cover may be provided that only covers the mounting groove 14 but does not press against the second guide portion 202. In other words, whether the electronic component 200 has a second guide portion 202, and whether the second guide portion 202 needs a second crimping member 3 (or the second cover) to press against it, is a matter for those skilled in the art to determine based on actual needs after learning the technical solution of this invention. This invention only limits the component used to press against the first guide portion 201 of the electronic component 200, which may be the first crimping member 2 or the first cover.

[0084] Understandably, when the electrical connector 100 has a second cover, but the second cover is not used to press against the second conductive part 202, the axial position of the second rotating shaft 33 can be set to a fixed position, and the second abutting part 51, the second crimping arm 32, and the second receiving part can be removed or modified accordingly. For example, when the second cover is in the open or closed position, the axial position of the second rotating shaft 33 is in the third position C.

[0085] In summary, the electrical connector 100 of the present invention has the following beneficial effects:

[0086] (1) By designing the axis position of the first rotating shaft 23 to be variable, when the first pressing member 2 is in the open position, the first position A is farther away from the first guide part 201 or the first abutment part 41, so that the first pressing arm 22 is also farther away from the first guide part 201 or the first abutment part 41 under the drive of the first rotating shaft 23, thereby realizing that the first pressing arm 22 gives way to the first guide part 201, so that the electronic component 200 can be installed or removed smoothly; at the same time, when the first pressing member 2 is in the closed position, the second position B is closer to the first guide part 201 or the first abutment part 41, so that the first pressing arm 22 is also closer to the first guide part 201 under the drive of the first rotating shaft 23, thereby shortening the second lever arm L2. At the instant before reaching the closed position, the first lever arm L1 and the reaction force F2 of the electrical connector 100 are determined. According to the lever principle F1L1=F2L2, the present invention shortens the second lever arm L2, thereby reducing the force F1 and the amount of force applied by the user, achieving a labor-saving effect. In summary, the electrical connector 100 of the present invention can both prevent the first crimping member 2 from hindering the installation or removal of the electronic component 200 and reduce the force applied by the user. In addition, the first crimping member 2 also engages with the protrusion 13 of the base 1 through the fastening part 27. At the moment of fastening, the user needs to overcome not only the reaction force F2 but also the blocking force of the protrusion 13. The present invention reduces the force applied by the user, resulting in a more significant improvement in the user experience.

[0087] It should be noted that at the instant before the first crimping member 2 closes, the magnitude of the reaction force F2 depends on the contact relationship (material, size, relative position, etc.) between the first terminal 4, the electronic component 200, and the first crimping arm 22. Therefore, when the contact relationship between the three remains unchanged, the reaction force F2 at the instant of closure remains unchanged. Thus, reducing the length of the second lever arm L2 can reduce the force F1. That is, for an electrical connector 100 where the first lever arm L1 and the reaction force F2 are already determined, compared to before adopting the technical solution of this invention, shortening the second lever arm L2 after adopting the solution of this invention can reduce the force F1 applied by the user.

[0088] (2) When the first pressing member 2 and the second pressing member 3 are both in the corresponding closed position, the distance between the pressing part 28 along the second direction X and the axis of the first rotating shaft 23 is defined as the first distance D1, and the distance between the pressing part 28 along the second direction X and the axis of the second rotating shaft 33 is defined as the second distance D2. The first distance D1 is greater than the second distance D2. Since the first distance D1 is greater than the second distance D2, according to the lever principle, the first lever arm L1 of the force F1 is increased, which can further reduce the force F1 and save more effort.

[0089] (3) Through the cooperation between the groove 26 and the step portion 34, the first pressing member 2 restricts the movement of the second pressing member 3. At the same time, the relief groove 25 accommodates the second body 31, which allows the first body 21 and the second body 31 to be staggered in a larger range in the second direction X, which is beneficial for the first pressing member 2 and the second pressing member 3 to limit each other, and both cover the mounting groove 14 in a larger area.

[0090] (4) The first accommodating space 151 is used to accommodate the first rotating shaft 23, and the second accommodating space 161 is used to accommodate the second rotating shaft 33. The dimension of the first accommodating space 151 along the second direction X is larger than the dimension of the second accommodating space 161 along the second direction X. Thus, the first accommodating space 151 is larger in size, which can provide movement space for the axis of the first rotating shaft 23; the second accommodating space 161 is smaller in size, which is beneficial for fixing the second rotating shaft 33, so as to fix the axis position of the second rotating shaft 33.

[0091] The above detailed description is only an illustration of a preferred embodiment of the present invention and is not intended to limit the patent scope of the present invention. Therefore, all equivalent technical changes made using the content of this invention's specification and illustrations are included within the patent scope of this invention.
