Description

[Technical Field]

[0001] This utility model relates to the field of electrical connectors, and more particularly to a card edge connector that facilitates automatic locking and unlocking of electronic cards. [Background Technology]

[0002] In the field of connectors, an existing electrical connector is mounted to a circuit board and used for mating with a connector clip. The connector has an insulating body and an ear clip mounted to the insulating body. The ear clip is rotatable relative to the insulating body between a locked position and an unlocked position. In the locked position, the ear clip engages the connector clip to prevent it from detaching from the connector. In the unlocked position, the ear clip releases its grip on the connector clip, allowing the user to remove it. The ear clip has a lever for manual pressing to rotate it from the locked position to the unlocked position. When the ear clip is in the locked position engaging the connector clip, the lever is located to the side of the connector clip, requiring space directly above the lever.

[0003] However, as the performance of existing docking cards improves, their size increases, and the inclusion of peripheral devices and heat dissipation components obstructs the space directly above the lever, making it difficult to turn the latch and release it from the docking card. Forcibly pulling out the docking card can easily damage the electrical connector or the docking card.

[0004] Therefore, it is necessary to provide a card edge connector that facilitates automatic locking and unlocking of electronic cards to overcome the above-mentioned defects. [Utility Model Content]

[0005] In view of the problems in the background technology, the purpose of this utility model is to provide a card edge connector that facilitates automatic locking and unlocking of electronic cards.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a card edge connector for docking with an electronic card, the electronic card including a docking part and a card locking part, comprising: a base, including a plug-in part and a mounting part located on the right side of the plug-in part, the upper surface of the plug-in part having a slot formed by a downward indentation along the vertical direction and a receiving groove located on the right side of the slot, the slot for receiving the docking part, and the receiving groove for receiving the card locking part; a locking block, disposed on the mounting part, the locking block sliding left and right relative to the mounting part to switch between a locking position and an unlocking position, the locking block holding the card locking part in the locking position to prevent the electronic card from detaching from the base body upwards, the locking block releasing the holding of the card locking part in the unlocking position; an unlocking mechanism, including a moving part and a spring piece, the moving part including a pushing part, a connecting rod part, an actuating part and at least one elastic part, the connecting rod part extending in the left and right direction and integrally connected to the pushing part and the spring piece; The actuator has a pushing part located to the left of the receiving slot, a part of the connecting rod located at the insertion part, the actuator is linked to the locking block, and the elastic part engages with the base body to provide an external force to the base body to the left; the spring is located at the mounting part and elastically abuts against the locking block to provide an external force to the lock to the left; during the process of inserting the electronic card downward into the slot, the part of the electronic card to the left of the latching part pushes the pushing part, thereby driving the actuator to move to the left, the elastic part elastically deforms and accumulates elastic force, the spring overcomes the force applied by the actuator to the locking block and pushes the locking block to the left, so that it moves from the unlocked position to the locked position; during the process of lifting the left end of the electronic card relative to the right end and tilting it upward from the slot, the part of the electronic card to the left of the latching part gives way to the pushing part, the elastic part elastically releases, thereby driving the actuator to move to the right, the actuator overcomes the force applied by the spring on the locking block and pushes the locking block to the right, so that the locking block moves from the locked position to the unlocked position.

[0007] Furthermore, the moving part and the spring are separate structures, with the spring being a metal component.

[0008] Furthermore, the elastic part is a spring arm structure and there are two of them. The two elastic parts are connected to the right end of the actuating part in an integral manner, one above the other.

[0009] Furthermore, the lock block is provided with a stop groove that extends in the left and right direction and penetrates the lock block downward. The actuating part has a limiting part that extends upward into the stop groove. The width of the stop groove in the left and right direction is greater than the width of the limiting part in the left and right direction, so that when the actuating part moves, the limiting part moves left and right in the stop groove and abuts against the wall of the stop groove to limit the locking position and unlocking position of the lock block.

[0010] Furthermore, the mounting part is provided with a sliding groove extending in the left-right direction, the sliding groove being at least partially higher than the upper surface of the insertion part; the locking block is accommodated in the sliding groove, and the locking block slides left and right relative to the sliding groove to switch between the locking position and the unlocking position.

[0011] Furthermore, the lock block has at least one stop surface, and the inner wall of the slide groove has at least one limiting surface corresponding to the stop surface. When the lock block slides from the unlock position to the latch position, the limiting surface is located to the left of the stop surface, so that the lock block is stopped by the limiting surface.

[0012] Furthermore, the locking block includes a locking plate portion and a sliding plate portion connected to the right side of the locking plate portion, wherein the sliding plate portion protrudes downward from the locking plate portion, and a stop surface is formed on the portion of the sliding plate portion that protrudes downward relative to the locking plate portion.

[0013] Furthermore, the top of the mounting part is provided with two reinforcing parts, which are spaced apart in the front-back direction to form a clearance groove. The reinforcing parts are used to strengthen the structural strength of the slide groove, and the clearance groove is used to accommodate the part of the electronic card located on the upper side of the card holder and to limit the electronic card in the front-back direction.

[0014] Furthermore, a recess is provided on the right side of the locking block, a part of the spring is fixedly assembled to the mounting part, and the other part of the spring extends into the recess and abuts against the locking block to the left to prevent the locking block from disengaging from the mounting part.

[0015] Furthermore, the mounting part includes a lower part and an upper part connected above the lower part. The lower part is connected to the right end of the plug-in part, and the upper part is the part of the mounting part that protrudes upward from the plug-in part. The upper part protrudes to the right from the lower part. The locking block is mounted on the upper part. A notch is formed on the right side of the lower part and the lower side of the upper part. The elastic part is at least partially exposed at the position of the notch. The spring piece protrudes upward into the upper part through the notch.

[0016] Furthermore, there are two elastic parts, both of which are connected to the right end of the actuating part and extend to the notch to abut against the lower part.

[0017] Furthermore, each elastic part includes an extension section and a bending section. The extension section extends from the right end of the actuating part to the right to the notch, and the bending section folds back from the extension section. The two bending sections abut against the lower part one after the other.

[0018] To achieve the above objectives, the present invention adopts the following technical solution:

[0019] The unlocking mechanism of this utility model is used so that when an electronic card is inserted downward into the slot, the portion of the electronic card to the left of the card-holding part pushes the abutment part, thereby driving the actuating part to move to the left. The elastic part elastically deforms and accumulates elastic force, and the spring overcomes the force applied by the actuating part to the locking block and pushes the locking block to the left, moving it from the unlocked position to the locked position. When the left end of the electronic card is raised relative to the right end and pulled upward from the slot, the portion of the electronic card to the left of the card-holding part gives way to the abutment part, and the elastic part elastically releases, thereby driving the actuating part to move to the right. The actuating part overcomes the force applied by the spring to the locking block and pushes the locking block to the right, moving the locking block from the locked position to the unlocked position. In this way, the card edge connector can automatically lock and unlock the electronic card, thereby facilitating the user's operation. [Attached Image Description]

Detailed Implementation Methods

[0032] To facilitate a better understanding of the purpose, structure, features, and effects of this utility model, the present utility model will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0033] In this utility model, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0034] like Figures 1 to 10 The diagram shows the card edge connector 100 of this utility model, using a PCI-E connector as an example, but not limited to PCI-E.

[0035] like Figure 1 and Figure 8 As shown, the card edge connector 100 is used to electrically connect an electronic card 200 to a circuit board (not shown). The electronic card 200 includes a mating part 201, a locking part 202, and a protrusion 203. The locking part 202 and the protrusion 203 are both spaced apart from the mating part 201, and the mating part 201 is located between the locking part 202 and the protrusion 203. Specifically, the protrusion 203 is located on the left side of the mating part 201, and the locking part 202 is located on the right side of the mating part 201. The mating part 201 is provided with a plurality of gold fingers (not shown), and the lower edge of the mating part 201 protrudes downward from the lower edge of the locking part 202 and the lower edge of the protrusion 203, respectively.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, the card edge connector 100 includes a base 1, multiple conductive terminals 2, a locking block 3, an unlocking mechanism, and two fixing members 6. The multiple conductive terminals 2 are disposed on the base 1 for electrically connecting the electronic card 200 and the circuit board (not shown). The locking block 3 is disposed at the right end of the base 1 and is slidable relative to the base 1. The locking block 3 has a locking position and an unlocking position relative to the base 1. The unlocking mechanism is disposed on the base 1 and is used to hold the locking block 3 in the locking position after the electronic card 200 is inserted and to hold the locking block 3 in the unlocking position before the electronic card 200 is inserted. The fixing members 6 are inserted into the base 1 from the bottom and are used to limit the unlocking mechanism and fix the card edge connector 100 to the circuit board (not shown).

[0037] like Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, the base 1 includes an insulating body (not labeled) and a metal shell (not labeled) covering the insulating body. In other embodiments, the base 1 may be made of insulating material only. The base 1 includes a plug-in portion 1A extending in the left-right direction X and a mounting portion 1B located at the right end of the plug-in portion 1A. The upper surface of the plug-in portion 1A is recessed with a slot 11 and a receiving groove 12. The slot 11 and the receiving groove 12 are spaced apart in the left-right direction X. The slot 11 is located to the left of the receiving groove 12. The slot 11 is used to receive the docking portion 201 of the electronic card 200, and the receiving groove 12 is used to receive the card holding portion 202. After the electronic card 200 is inserted into the base 1, the protrusion 203 is located outside the plug-in portion 1A and to the left of the plug-in portion 1A. A receiving groove 13 is recessed upward on the lower surface of the base 1. The receiving groove 13 is located below the slot 11 and is vertically connected to the slot 11. The receiving groove 13 is used to receive the unlocking mechanism. In this embodiment, the receiving groove 13 penetrates the base 1 in the left-right direction X and penetrates the base 1 downward. The plug-in part 1A and the mounting part 1B are integrally connected. However, in other embodiments, the plug-in part 1A and the mounting part 1B can also be set separately. That is, the plug-in part 1A and the mounting part 1B are injection molded separately and set separately on the circuit board or assembled together and set on the circuit board.

[0038] like Figure 6 and Figure 7 As shown, the mounting portion 1B protrudes upward from the insertion portion 1A. The mounting portion 1B has a groove 14 for receiving the locking block 3. Specifically, the groove 14 is a hole-like opening that extends through the mounting portion 1B in the left-right direction X. The groove 14 is at least partially higher than the upper surface of the insertion portion 1A. It is understood that in other embodiments, the groove 14 may be formed on the outer side of the mounting portion 1B in the front-rear direction Y, so that the locking block 3 can be fitted onto the outer side of the mounting portion 1B and slide relative to the groove 14. The inner wall surface of the groove 14 has at least one limiting surface 141. Specifically, the limiting surface 141 is arranged to the right and outwards. The limiting surface 141 is used to limit and cooperate with the locking block 3 in the left-right direction X to prevent the locking block 3 from disengaging from the groove 14 to the left.

[0039] like Figure 2 and Figure 3 As shown, the mounting part 1B includes a lower part 16 and an upper part 15 connected above the lower part 16. The lower part 16 is connected to the right end of the insertion part 1A. The upper part 15 is the part of the mounting part 1B that protrudes upward from the insertion part 1A. The upper part 15 protrudes to the right from the lower part 16. The locking block 3 is mounted on the upper part 15. A notch 17 is formed on the right side of the lower part 16 and the lower side of the upper part 15.

[0040] like Figure 3 and Figure 5As shown, the top of the mounting part 1B is provided with two reinforcing parts 151. The two reinforcing parts 151 are spaced apart along the front-rear direction Y to form a clearance groove 152. The reinforcing parts 151 are used to strengthen the structural strength of the slide groove 14. The clearance groove 152 is used to accommodate the part of the electronic card 200 located on the upper side of the card holder 202, and to limit the electronic card 200 in the front-rear direction Y.

[0041] like Figure 1 and Figure 2 As shown, multiple conductive terminals 2 are arranged in two rows, one in front and one behind. The two rows of conductive terminals 2 are inserted from the bottom surface of the insertion part 1A upwards to the two side walls. Each conductive terminal 2 includes a contact part (not shown) exposed in the slot 11 along the front-back direction Y, a welding part (not labeled) protruding downwards from the mounting surface, and a fixing part (not shown) connecting the contact part and the welding part. The contact part is used to contact the mating part 201 of the insertion slot 11 to realize the electrical connection between the card edge connector 100 and the electronic card 200. The welding part is used to weld to the circuit board to realize the electrical connection between the card edge connector 100 and the circuit board. The fixing part is fixed to the corresponding side wall.

[0042] like Figure 3 , Figure 7 and Figure 9 As shown, the locking block 3 is installed in the slide groove 14 from right to left and can slide left and right relative to the slide groove 14 to switch between the locking position and the unlocking position. The locking block 3 is provided with a stop groove 31, which extends in the left-right direction X and penetrates the locking block 3 downward. It can be understood that the stop groove 31 can penetrate the locking block 3 only downward, or it can penetrate the locking block 3 both upward and downward. Specifically, in this embodiment, the stop groove 31 penetrates the locking block 3 both upward and downward. The locking block 3 is provided with at least one stop surface 32 corresponding to the limiting surface 141. Specifically, there are two stop surfaces 32, which are respectively arranged one in front of the other on both sides of the stop groove 31. When the locking block 3 slides from the unlocking position to the locking position, the limiting surface 141 is located to the left of the stop surface 32, so that the locking block 3 is stopped by the limiting surface 141.

[0043] like Figure 4 and Figure 7 As shown, the locking block 3 includes a latching plate portion 33 and a sliding plate portion 34 connected to the right side of the latching plate portion 33. The latching plate portion 33 extends to the left through the sliding groove 14 to lock the locking portion 202. The sliding plate portion 34 slides relative to the sliding groove 14. Specifically, the sliding plate portion 34 protrudes downward from the latching plate portion 33, and a stop surface 32 is formed on the left side surface of the portion of the sliding plate portion 34 that protrudes downward relative to the latching plate portion 33. The right side of the locking block 3 has a recess 35. Specifically, the recess 35 is formed on the sliding plate portion 34, and a stop groove 31 is provided on both the latching plate portion 33 and the sliding plate portion 34.

[0044] like Figure 3 , Figure 4and Figure 6 As shown, the unlocking mechanism includes a movable component 4 and a spring piece 5 located on the right side of the movable component 4. The movable component 4 is located on the base 1 and can move relative to the base 1 in the left-right direction X. The movable component 4 is mainly used to apply an external force to the lock block 3 to the right, and the spring piece 5 is mainly used to apply an external force to the lock block 3 to the left. Specifically, the movable component 4 and the spring piece 5 are separate structures, and both the movable component 4 and the spring piece 5 are made of metal.

[0045] like Figure 4 , Figure 6 and Figure 8 As shown, the movable member 4 is located at the bottom of the base 1. The movable member 4 includes a pushing part 41, a connecting rod part 42, an actuating part 43 and at least one elastic part 44, which are integrally stamped from a metal sheet. The connecting rod part 42 extends in the left-right direction X and integrally connects the pushing part 41 and the actuating part 43. The pushing part 41 is located to the left of the receiving groove 12. A part of the connecting rod part 42 is located in the insertion part 1A. Specifically, the connecting rod part 42 is received in the receiving groove 13. The actuating part 43 is linked with the locking block 3. The elastic part 44 is engaged with the base 1 to give the base 1 an external force to the left.

[0046] like Figure 3 and Figure 8 As shown, the push part 41 is located at the left end of the slot 11. The push part 41 has a guide slope 411, which extends inclinedly from the upper end of the push part 41 to the lower right. During the process of the docking part 201 being inserted into the slot 11 along the guide slope 411, the docking part 201 abuts against the push part 41, causing the push part 41 to shift to the left and exit out of the slot 11 to make room for the docking part 201 to be inserted. Specifically, the height of the push part 41 is higher than that of the connecting rod part 42. The top surface of the push part 41 is closer to the top surface of the insertion part 1A in the vertical direction Z than the bottom surface of the insertion part 1A. This is so that when the docking part 201 is inserted into the slot 11, the docking part 201 can first abut against the guide slope 411, thereby driving the push part 41 to move to the left, that is, the moving part 4 as a whole is displaced to the left. In other embodiments, the pushing part 41 may also be provided on the left side of the insertion part 1A and used in conjunction with the protrusion 203.

[0047] like Figure 7 and Figure 9 As shown, the actuating part 43 is provided in the mounting part 1B. The actuating part 43 has a limiting part 431 extending upward into the stop groove 31. The width of the stop groove 31 in the left-right direction X is greater than the width of the actuating limiting part 431 in the left-right direction X, so that when the actuating part 43 moves, the limiting part 431 moves left and right in the stop groove 31 and abuts against the wall of the stop groove 31 to limit the locking position and unlocking position of the lock block 3.

[0048] like Figure 2 and Figure 3As shown, there are two elastic portions 44. Specifically, the two elastic portions 44 are connected one above the other to the right end of the actuating part 43 and extend to the notch 17 to abut against the lower part 16. In other embodiments, the elastic portions 44 can also be provided in other positions, such as the front or rear side of the seat 1. There is no specific limitation, and they can be set according to the actual situation. Each elastic portion 44 includes an extension section 441 and a bending section 442. The extension section 441 extends to the right from the right end of the actuating part 43 to the notch 17, and the bending section 442 bends back from the extension section 441. The two bending sections 442 abut against the lower part 16 one after the other. Understandably, with such a design, the elastic part 44 is less likely to undergo a sol-gel reaction with the seat 1 when the card edge connector 100 is too hot. Even if a sol-gel reaction occurs, it will not affect the elastic action of the elastic part 44. If the elastic part 44 is a linear spring, the sol-gel reaction will hinder the compression or extension of the linear spring, which will affect the automatic unlocking and automatic locking of the locking block 3.

[0049] like Figure 4 and Figure 9 As shown, the spring piece 5 is installed upward on the mounting part 1B through the notch 17 and protrudes upward into the upper part 15. A part of the spring piece 5 is fixedly assembled to the lower part 16 of the mounting part 1B, and the other part of the spring piece 5 extends into the recess 35 and abuts against the locking block 3 to the left to prevent the locking block 3 from disengaging from the slide groove 14 of the mounting part 1B.

[0050] like Figure 3 and Figure 4 As shown, there are two fixing members 6. After the movable member 4 is installed on the base 1, the fixing members 6 are respectively inserted upward into the insertion part 1A. The fixing members 6 are used to support the connecting rod part 42 upward, and the connecting rod part 42 can move left and right relative to the fixing members 6.

[0051] like Figures 5 to 7 As shown, before the electronic card 200 is inserted into the slot 11, the guide slope 411 of the pushing part 41 is located inside the slot 11, the elastic part 44 abuts against the lower part 16 to the left, and the limiting part 431 abuts against the right side wall of the stop groove 31 to the right, giving the locking block 3 an external force to the right. The spring piece 5 gives the locking block 3 an external force to the left, but the external force given to the locking block 3 by the elastic part 44 to the right is greater than the external force given to the locking block 3 by the spring piece 5 to the left, so that the locking block 3 is in the unlocked position.

[0052] like Figure 8 and Figure 9As shown, during the process of inserting the electronic card 200 downward into the slot 11, the electronic card 200 pushes the push part 41 along the guide slope 411 at the docking part 201 to the left of the card latch 202, causing the push part 41 to move to the left and exit out of the slot 11 to the left, causing the moving part 4 to move to the left as a whole, driving the actuating part 43 to move to the left, and the elastic part 44 elastically deforms and accumulates elastic force. At this time, the actuating part 43 reduces the external force to the right of the latch, and the force of the spring piece 5 on the locking block 3 to the left is greater than the force of the actuating part 43 on the locking block 3 to the right. The spring piece 5 overcomes the force applied by the actuating part 43 to the locking block 3 and pushes the locking block 3 to the left, so that it moves from the unlocked position to the latched position.

[0053] like Figure 6 and Figure 10 As shown, during the process of lifting the left end of the electronic card 200 relative to the right end and tilting it upward from the slot 11, the electronic card 200 makes way for the pushing part 41 at the docking part 201 to the left of the card latching part 202, the elastic part 44 is released elastically, and the moving part 4 moves to the right as a whole, thereby driving the actuating part 43 to move to the right. At this time, the limiting part 431 abuts against the right side of the stop groove 31, and the force of the actuating part 43 on the locking block 3 to the right is greater than the force of the spring piece 5 on the locking block 3 to the left. The actuating part 43 overcomes the force applied by the spring piece 5 on the locking block 3 and pushes the locking block 3 to the right, so that the locking block 3 moves from the latching position to the unlocking position.

[0054] The beneficial effects of the edge connector 100 of this utility model are as follows:

[0055] 1. The unlocking mechanism of this utility model is used so that when the electronic card 200 is inserted downward into the slot 11, the portion of the electronic card 200 to the left of the card-holding part 202 pushes the abutment part 41, thereby driving the actuating part 43 to move to the left. The elastic part 44 elastically deforms and accumulates elastic force. The spring piece 5 overcomes the force applied by the actuating part 43 to the locking block 3 and pushes the locking block 3 to the left, moving it from the unlocked position to the locked position. When the left end of the electronic card 200 is raised relative to the right end and pulled upward from the slot 11, the portion of the electronic card 200 to the left of the card-holding part 202 gives way to the abutment part 41. The elastic part 44 elastically releases, thereby driving the actuating part 43 to move to the right. The actuating part 43 overcomes the force applied by the spring piece 5 to the locking block 3 and pushes the locking block 3 to the right, moving the locking block 3 from the locked position to the unlocked position. This realizes the automatic locking and unlocking of the electronic card 200 by the card edge connector 100, thereby facilitating user operation.

[0056] 2. The moving part 4 and the spring piece 5 respectively apply two opposite forces to the locking block 3. The moving part 4 and the spring piece 5 are set separately, which makes it easier to process and shape the moving part 4 and the spring piece 5, and helps to reduce processing costs.

[0057] 3. Two elastic parts 44 are provided, which helps to increase the elastic force of the elastic parts 44, making the elastic force of the elastic parts 44 greater than that of the spring piece 5. The two elastic parts 44 are integrally connected to the right end of the actuating part 43 with one on top of the other, which is beneficial to the integral molding of the moving part 4.

[0058] 4. The limiting part 431 of the actuating part 43 passes through the stop groove 31 of the lock block 3. The width of the stop groove 31 in the left-right direction X is greater than the width of the limiting part 431 in the left-right direction X. This allows the limiting part 431 to move left and right in the stop groove 31 and abut against the wall of the stop groove 31, thereby limiting the locking position and unlocking position of the lock block 3.

[0059] 5. The locking block 3 is set in the slide groove 14 and moves in the left-right direction X relative to the slide groove 14. The locking block 3 is sleeved on the outside of the mounting part 1B. The locking block 3 is set in this way, so the volume is small and the force required to push it is also small.

[0060] 6. The stopping surface 32 of the locking block 3 and the limiting surface 141 of the inner wall of the slide groove 14 cooperate with each other, so that when the locking block 3 slides from the unlock position to the locking position, the stopping surface 32 is stopped by the limiting surface 141 located on the left side, thus preventing the locking block 3 from disengaging from the slide groove 14 to the left.

[0061] 7. The locking plate portion 33 is used to lock the locking portion 202. The sliding plate portion 34 slides in the sliding groove 14. The sliding plate portion 34 protrudes downward from the locking plate portion 33. On the one hand, it is beneficial to increase the height of the bottom surface of the locking plate portion 33, which is beneficial to locking the locking portion 202. On the other hand, it is convenient to form a stop surface 32 between the locking plate portion 33 and the sliding plate portion 34.

[0062] 8. The reinforcing part 151 is used to strengthen the structural strength of the slide 14 and prevent the wall of the slide 14 from cracking during the sliding process of the locking block 3. The clearance groove 152 between the two reinforcing parts 151 is used to accommodate the electronic card 200 on the upper side of the card latch 202.

[0063] 9. A portion of the spring piece 5 is fixedly assembled in the recess 35, and the other portion of the spring piece 5 extends into the recess 35 and abuts against the locking block 3 to the left. On the one hand, the other portion of the spring piece 5 is limited by the recess 35 in the front-back direction Y, which helps to maintain the abutting position of the spring piece 5 and the locking block 3, so that the force of the spring piece 5 abutting against the locking block 3 to the left is uniform. On the other hand, the spring piece 5 can prevent the locking block 3 from disengaging from the slide groove 14 to the right.

[0064] 10. To facilitate the installation of the movable part 4 and the spring piece 5, the mounting part 1B is configured as an upper part 15 and a lower part 16, and the upper part 15 protrudes to the right of the lower part 16 to form a notch 17 on the right side of the lower part 16 and the lower side of the upper part 15. In this way, on the one hand, it is beneficial for the elastic part 44 to be partially exposed through the notch 17 to provide space for the elastic part 44 to deform elastically, and on the other hand, it is beneficial for the spring piece 5 to protrude upward into the upper part 15 through the notch 17.

[0065] 11. Two elastic parts 44 are provided, which helps to increase the elastic force of the elastic parts 44, making the elastic force of the elastic parts 44 greater than that of the spring piece 5. Both elastic parts 44 are connected to the right end of the actuating part 43 and extend to the notch 17 to abut against the lower part 16. This arrangement is beneficial to the installation of the elastic parts 44, and when the edge connector 100 is too hot, the elastic parts 44 are not easy to react with the base 1.

[0066] 12. The elastic part 44 includes a bent section 442 and an extension section 441 connecting the bent section 442 and the actuating part 43. The two bent sections 442 are integrally connected to the right end of the actuating part 43, one in front and one behind. This helps the moving part 4 to maintain balance during the movement process and avoids the moving part 4 from being biased to one side.

[0067] The above detailed description is only a description of the preferred embodiment of this utility model and is not intended to limit the patent scope of this utility model. 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.

Claims

1. A card edge connector for mating with an electronic card, the electronic card including a mating portion and a card latching portion, characterized in that: include: A body includes a plug-in part and a mounting part located on the right side of the plug-in part. The upper surface of the plug-in part is provided with a slot formed by a downward indentation along the vertical direction and a receiving groove located on the right side of the slot. The slot is used to receive the docking part, and the receiving groove is used to receive the locking part. A locking block is provided on the mounting part. The locking block slides left and right relative to the mounting part to switch between a locking position and an unlocking position. When the locking block is in the locking position, it holds the card latch and prevents the electronic card from detaching from the base. When the locking block is in the unlocking position, it releases the holding on the card latch. An unlocking mechanism includes a movable member and a spring. The movable member includes a pushing part, a connecting rod part, an actuating part, and at least one elastic part. The connecting rod part extends in a left-right direction and integrally connects the pushing part and the actuating part. The pushing part is located to the left of the receiving groove. A portion of the connecting rod part is located in the insertion part. The actuating part is linked to the locking block. The elastic part engages with the base body to provide an external force to the base body to the left. The spring is located in the mounting part and elastically abuts against the locking block to provide an external force to the lock to the left. During the process of inserting the electronic card downward into the slot, the part of the electronic card to the left of the card latch pushes the push part, thereby driving the actuator to move to the left. The elastic part elastically deforms and accumulates elastic force. The spring overcomes the force applied by the actuator to the locking block and pushes the locking block to the left, moving it from the unlocked position to the latched position. As the electronic card is tilted upward from the slot with its left end raised relative to its right end, the portion of the electronic card to the left of the card latch gives way to the pusher, and the elastic part is released elastically, thereby driving the actuator to move to the right. The actuator overcomes the force exerted by the spring on the lock block and pushes the lock block to the right, so that the lock block moves from the latch position to the unlock position.
