Description

Technical Field

[0001] The present invention relates to a socket connector, and particularly to a socket connector with a simple structure, convenient installation, reduced space occupation and an automatic card ejection function.

Background Art

[0002] An existing socket connector is installed on a circuit board and used for plugging and mating with a docking card. The electrical connector includes an insulating body extending longitudinally in the left-right direction. The insulating body includes a socket, a mounting portion and an extension base. The mounting portion and the extension base are respectively arranged at the left and right ends of the socket. An ear buckle is installed on the mounting portion and can rotate between a locking position and an unlocking position. The ear buckle holds the docking card in the locking position and releases the holding of the docking card in the unlocking position, so that the user can remove the docking card from the electrical connector. The socket connector further includes an unlocking assembly, which includes an abutting portion, an elastic piece and an actuating portion. The abutting portion is exposed in the socket, and the elastic piece and the actuating portion are located on the extension base outside the socket. During the process of inserting the docking card into the socket, the docking card abuts against the abutting portion protruding into the socket. The abutting portion is displaced to allow the docking card to continue to be inserted into the socket, and the elastic piece is squeezed to deform. During the process of pulling the left end of the docking card obliquely upward relative to its right end out of the socket, the docking card no longer pushes against the abutting portion. The elastic piece restores deformation to drive the abutting portion to reset, and drives the actuating portion to actuate the ear buckle, so that the ear buckle rotates from the locking position to the unlocking position. However, since an additional extension base is provided in the left-right direction on the insulating body to receive the elastic piece and the actuating portion, the length of the original specification of the socket connector is increased. Furthermore, when installing this connector on the circuit board, it will occupy more space on the circuit board and block the installation of other electronic components. And the elastic piece is formed by bending a metal sheet, and its elastic force is small. For a relatively heavy docking card, the elastic force of this elastic portion is not enough to push the ear buckle to rotate. At the same time, the upper part of the extension base is provided with an open mouth, and the upwardly bent part of the elastic piece is exposed outside the extension base and is not blocked. Thus, the elastic piece is not firmly fixed and is easy to loosen or even fall off when touched.

[0003] Therefore, it is necessary to provide a socket connector with a simple structure, convenient installation, reduced space occupation and an automatic card ejection function to overcome the above defects.

Summary of the Invention

[0004] Aiming at the problems in the background art, the purpose of the present invention is to provide a socket connector with a simple structure, convenient installation, reduced space occupation and an automatic card ejection function.

The abutting portion is exposed on a side of the socket away from the mounting portion, and the abutting portion has a guiding inclined surface. The actuating portion is mounted on the mounting portion, and the actuating portion includes a pushing portion and a support arm. The pushing portion is located in the mounting groove for pushing the ear buckle to unlock, and the support arm abuts against the elastic member in the left-right direction; during the process of the docking card being inserted downward into the socket, one side of the docking card is displaced downward along the guiding inclined surface and abuts and pushes the abutting portion to displace away from the ear buckle, driving the pushing portion to displace away from the ear buckle to make way for the pushing portion. The support arm presses against the elastic member to elastically store energy in the elastic member. The bottom of the other side of the docking card touches the pushing portion, causing the ear buckle to automatically rotate until the locking portion holds the docking card; during the process of the docking card being tilted and pulled out upward, one side of the docking card releases the abutting portion, and the moving member moves toward the ear buckle under the restoring force of the elastic member, thereby driving the pushing portion to push the ear buckle to rotate and unlock, so that the locking portion releases the holding of the other side of the docking card.

[0006] Further, there are two receiving grooves, and the two receiving grooves are located on both sides of the mounting groove in the front-rear direction.

[0014] Further, the mounting portion includes two mounting walls. The two mounting walls are spaced apart in the front-rear direction to form the mounting groove. An inner side surface of each mounting wall is provided with a guiding groove and a rotating shaft hole communicating with the guiding groove in the left-right direction. The guiding groove is located on a side away from the slot relative to the rotating shaft hole and penetrates through one end of the mounting wall in the left-right direction. The guiding groove and the rotating shaft hole are spaced apart from the receiving groove in the front-rear direction. The ear buckle includes two rotating shafts corresponding to the two rotating shaft holes one by one. The rotating shafts are snapped into the rotating shaft holes through the guiding grooves in the left-right direction to be rotationally matched with the rotating shaft holes.

[0015] Further, the abutting portion includes a metal core and a coating portion injection-molded outside the metal core. The metal core is connected to one end of the connecting portion away from the actuating portion, and the guiding inclined surface is formed on the coating portion.

[0016] Further, the coating portion is located above the connecting portion and is spaced from the bottom wall surface of the slot.

[0017] Further, a plurality of the conductive terminals are arranged in two rows and located on the front and rear sides of the slot. Each conductive terminal is provided with a contact portion, and the contact portions of the two rows of conductive terminals all protrude into the slot. Concave regions are respectively provided on the front and rear sides of the coating portion. The concave regions correspond to the contact portions of the conductive terminals in the up-down direction to make way for the contact portions during the left-right movement of the abutting portion.

[0018] Further, the docking card includes a docking portion, an extending portion and a buckling portion located on the left and right sides of the docking portion. When the docking portion is inserted into the slot, the docking portion is in electrical contact with the contact portion of the conductive terminal. The buckling portion is received in the mounting groove and held by the locking portion. The extending portion is located outside the slot and is spaced from the coating portion in the left-right direction.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The receiving grooves are arranged on the front and rear sides of the mounting part, so that the receiving grooves and the mounting grooves are arranged side by side in the front and rear directions, so that the length dimension of the insulating body along the left and right directions will not be increased, and when the slot connector is installed on the circuit board, the space for installing the electronic components on the circuit board will not be occupied. The elastic member is accommodated in the receiving groove, and the support arm of the moving member extends into the receiving groove to abut against the elastic member. This not only facilitates the installation of the elastic member, but also limits the elastic member from being easily separated from the receiving groove when the support arm actuates the elastic member, that is, the elastic member will not be touched by other objects and will not fall off easily. The elastic member is a spring extending in the left and right directions, and elastically compresses and elastically recovers in the receiving groove in the left and right directions. Compared with the elastic sheet structure in the prior art, the spring has a better elastic effect and a larger elastic compression stroke. On the one hand, it is easy to give the moving member a suitable driving force when the elastic member recovers so as to easily push the ear buckle to unlock, and on the other hand, it is prevented from being overly compressed and unable to return to the original position, so as to ensure that the elastic member always has a suitable elastic resistance force while increasing the service life of the elastic member, so as to ensure that the entire unlocking assembly can run smoothly after the docking card is plugged and unplugged many times.

[0046] For better understanding of the purpose, structure, features, and efficacy of the present invention, etc., the present invention will be further described below in conjunction with the drawings and specific implementation manners.

[0047] In the following description, unless otherwise specified, the directional terms such as "up", "down", "left", "right", "front", and "back" are referenced to the reference direction in the typical application environment of the present invention, that is, a main perspective is selected to determine the above directions. In the present invention, the left-right direction is defined as the X-axis direction, the front-back direction is defined as the Y-axis direction, and the up-down direction is defined as the Z-axis direction. Among them, the right direction in the left-right direction X is the positive direction of the X-axis direction, the forward direction in the front-back direction Y is the positive direction of the Y-axis direction, and the upward direction in the up-down direction Z is the positive direction of the Z-axis direction. It can be understood that the direction positioning of the present invention is for better understanding of the relative position relationship and movement direction between components. In actual use, the direction positioning of the present invention can be adjusted according to the application environment. For example, the front and the back can be interchanged, and the left and the right can also be interchanged, etc.

[0048] As Figures 1 to 15 shown in the drawings of the first embodiment of the present invention, Figures 16 to 21 shown in the drawings of the second embodiment that is different from the first embodiment of the present invention. Among them, most of the structures in the first embodiment and the second embodiment are the same, and only some structures are different.

[0049] As Figure 1 , Figure 2 and Figure 20As shown, the socket connector 100 of the present invention is respectively used for electrically connecting with the docking card 200 and the circuit board 300. That is, the circuit board 300 is electrically connected to the docking card 200 through the socket connector 100 to transmit electrical signals from the circuit board 300 to the socket connector 100 and then to the docking card 200. Specifically, the socket connector 100 is located above the circuit board 300, and the docking card 200 is inserted downward into the socket connector 100. Specifically, the socket connector 100 in this embodiment is specifically a PCIE 5.0. Of course, in other embodiments, it can also be other socket-type electrical connectors.

[0050] As Figure 1 , Figure 2 and Figure 20 shown, in any embodiment, the docking card 200 is provided with a guiding portion 201, a buckle portion 202 located on the right side of the guiding portion 201 along the left-right direction X, and an extending portion 203 located on the left side. The guiding portion 201, the buckle portion 202, and the extending portion 203 are all located at the lower end of the docking card 200 and are spaced apart from each other in the left-right direction X. Among them, the guiding portion 201 is used for electrically connecting with the socket connector 100, and the buckle portion 202 is used to be held by the socket connector 100 to prevent the docking card 200 from disengaging upward from the socket connector 100. The extending portion 203 is located outside the socket connector 100.

[0051] As Figure 2 , Figure 3 and Figure 16 shown, in any embodiment, the socket connector 100 includes an insulating body 1, a plurality of conductive terminals 2, an ear buckle 3, an unlocking component, a first fixing member 6, and a second fixing member 7. The plurality of conductive terminals 2 are arranged on the insulating body 1. The ear buckle 3 is rotatably mounted at one end of the insulating body 1. The ear buckle 3 has a locking position and an unlocking position relative to the insulating body 1. The unlocking component is mounted to the socket connector 100 and is used to switch the ear buckle 3 from the locking position to the unlocking position. After the unlocking component is installed, the first fixing member 6 and the second fixing member 7 are installed on the insulating body 1 to fix the socket connector 100 to the circuit board 300. After the unlocking component is installed, the first fixing member 6 and the second fixing member 7 are used to support the unlocking component upward. The difference between the second embodiment and the first embodiment lies in: different partial structures of the unlocking component and the structural cooperation of different partial structures between the insulating body 1 and the unlocking component. Other structures of the second embodiment can refer to the first embodiment.

[0052] As Figure 7 , Figure 8 and Figure 16As shown, in any embodiment, the insulating body 1 is made of an insulating material and includes an integrally formed plugging portion 10a and a mounting portion 10b located on the right side of the plugging portion 10a. Specifically, the mounting portion 10b protrudes rightward from the plugging portion 10a, and the bottom surface of the plugging portion 10a is lower than the bottom surface of the mounting portion 10b in the up-down direction Z. In the front-back direction Y, the width of the plugging portion 10a is equal to the width of the mounting portion 10b.

[0053] As Figure 2 and Figure 3 、 Figure 19 and Figure 20 As shown, in any embodiment, the plugging portion 10a includes two side walls 11, a left end wall 12a, a right end wall 12b, a bottom wall 13, and an anti-fooling portion 15. The two side walls 11 are opposite and spaced apart in the front-back direction Y. The left end wall 12a and the right end wall 12b are opposite and spaced apart in the left-right direction X. The bottom wall 13 connects the two side walls 11, the left end wall 12a, and the right end wall 12b. The two side walls 11, the left end wall 12a, and the bottom wall 13 together define a slot 14 for receiving the conducting portion 201 of the docking card 200. The anti-fooling portion 15 extends downward from the top surface of the plugging portion 10a to the bottom wall 13 and divides the slot 14 into a long slot 141 and a short slot 142 in the left-right direction X. The short slot 142 is located between the left end wall 12a and the anti-fooling portion 15, and the long slot 141 is located between the right end wall 12b and the anti-fooling portion 15.

[0054] As Figure 6 、 Figure 7 、 Figure 14 and Figure 16 As shown, in any embodiment, the bottom wall 13 includes a base portion 132 and a plurality of partitions 133 extending from the front and rear sides of the base portion 132 to the two side walls 11. The plurality of partitions 133 on the same side of the base portion 132 are spaced apart in the left-right direction X and separate the corresponding plurality of conductive terminals 2 from each other. A strip-shaped groove 131 extending in the left-right direction X is recessed upward on the bottom surface of the base portion 132. Both ends of the strip-shaped groove 131 penetrate upward through the base portion 132 in the left-right direction X. The two ends of the strip-shaped groove 131 communicate with the long slot 141 and the short slot 142 respectively. Specifically, the strip-shaped groove 131 penetrates upward through the base portion 132 at a position adjacent to the anti-fooling portion 15 and at a position adjacent to the right end wall 12b. The middle part of the strip-shaped groove 131 does not penetrate upward through the base portion 132, so as to ensure the connection strength of the bottom wall 13 and prevent the bottom wall 13 from breaking when the docking card 200 is inserted into the slot 14. It can be understood that in other embodiments, the strip-shaped groove 131 may also be discontinuously penetrating upward through the base portion 132, as long as both ends of the strip-shaped groove 131 penetrate upward through the base portion 132 and communicate with the long slot 141 and the short slot 142 respectively, and no specific limitation is made here.

[0055] As Figure 6As shown, in the first embodiment, specifically, the width of the strip-shaped groove 131 in the front-back direction Y remains consistent throughout, and at the position of the short groove 142, the strip-shaped groove 131 only penetrates the base 132 vertically and does not extend to the partition 133.

[0056] As Figure 16 shown, in the second embodiment, specifically, the bottom wall is further provided with a through-hole 134. The through-hole 134 is located in the short groove 142 and communicates with the left side of the strip-shaped groove 131. The through-hole 134 penetrates the base 132 vertically and disconnects the connection between the base 132 and part of the partition 133 on the front and back sides of the base 132. That is, the width of the through-hole 134 in the front-back direction is greater than the width of the strip-shaped groove 131 in the front-back direction.

[0057] As Figure 14 and Figure 20 shown, in any embodiment, the left end wall 12a is provided with a first through-hole 121 that penetrates in the left-right direction X. The first through-hole 121 communicates with the short groove 142. The right end wall 12b is provided with a second through-hole 122 that penetrates in the left-right direction X and vertically downward. The second through-hole 122 communicates with the long groove 141 and the strip-shaped groove 131. Specifically, both the first through-hole 121 and the second through-hole 122 extend in the up-down direction Z.

[0058] As Figure 4 and Figure 14 shown, in any embodiment, the mounting portion 10b includes two mounting walls 16 and two outwardly expanding portions 18 that extend rightward from the outer side surface of the right end wall 12b.

The mounting groove 17 communicates with the long groove 141 through the second through-hole 122. A guiding groove 162 and a rotating shaft hole 161 that communicates with the guiding groove 162 in the left-right direction X are recessed on the inner side surface of each mounting wall 16. The guiding groove 162 is located on the side away from the slot 14 relative to the rotating shaft hole 161 and penetrates one end of the mounting wall 16 in the left-right direction X. The guiding groove 162 and the rotating shaft hole 161 are spaced apart from the receiving groove 181 in the front-back direction Y. Specifically, the opening of the guiding groove 162 is in a flared shape, is juxtaposed with the rotating shaft hole 161 in the left-right direction X, and is correspondingly arranged with the receiving groove 181 in the front-back direction Y.

[0059] As Figure 4 and Figure 15As shown, in any embodiment, two outwardly extending portions 18 respectively protrude from the outer side surface of the mounting wall 16 and are located at the bottom of the mounting wall 16. The outwardly extending portion 18 is provided with a receiving groove 181 that penetrates the outwardly extending portion 18 to the right. The receiving groove 181 is isolated from the mounting groove 17. Specifically, each outwardly extending portion 18 is provided with a receiving groove 181. In other embodiments, a receiving groove 181 may also be provided on only one side. Specific limitations are not made here. The receiving groove 181 is arranged side by side with the guiding groove 162 in the front-rear direction Y. With this arrangement, the receiving groove 181 is provided only on the front and rear sides of the original mounting portion 10b, without increasing the length of the insulating body 1 in the left-right direction X, which is beneficial to reducing the space occupied by the circuit board 300 when mounted on the circuit board 300. The inner wall surface of the receiving groove 181 is provided with two notches 182 that extend in the left-right direction X and penetrate the outwardly extending portion 18. The two notches 182 are both formed by extending leftward from the opening side of the receiving groove 181. Specifically, the two notches 182 are arranged opposite to each other in the up-down direction Z. In other embodiments, the two notches 182 may also be arranged opposite to each other in the front-rear direction Y, or in other directions. Or one of the two notches 182 may be provided on the inner wall surface of the receiving groove 181 in the up-down direction Z, and the other may be provided on the inner wall surface of the receiving groove 181 in the front-rear direction Y. Specific limitations are not made here. At the same time, it can be understood that the number of notches 182 can also be selected according to actual situations, and can be one or multiple.

[0060] As Figure 2 , Figure 3 and Figure 19 As shown, in any embodiment, a plurality of conductive terminals 2 are arranged in two rows in the front-rear direction.

Each conductive terminal 2 includes a contact portion 21 exposed in the insertion slot 14 in the front-rear direction Y, a welding portion 22 protruding downward from the insertion portion 10a, and a fixing portion 23 connecting the contact portion 21 and the welding portion 22. The contact portion 21 is used to contact the connection portion 201 inserted into the insertion slot 14 to achieve electrical connection between the socket connector 100 and the docking card 200. The welding portion 22 is used to be welded to the circuit board 300 to achieve electrical connection between the socket connector 100 and the circuit board 300. The fixing portion 23 is fixed to the corresponding side wall 11.

[0061] As Figure 3 , Figure 8 , Figure 11 and Figure 20As shown, in any embodiment, the ear hook 3 is pivotally connected to the mounting portion 10b in the left-right direction X. The ear hook 3 is provided with a positioning groove 31 penetrating through the ear hook 3 in the left-right direction X, a locking portion 32 located above the positioning groove 31, a pushing portion 33 located below the positioning groove 31, and two rotating shafts 34 located on the front and rear sides of the pushing portion 33. The positioning groove 31 is used to receive the buckling portion 202, and the positioning groove 31 partially overlaps with the mounting groove 17. The locking portion 32 is used to downwardly block the buckling portion 202 received in the positioning groove 31 when the ear hook 3 is in the locked position, preventing the buckling portion 202 from disengaging upward from the ear hook 3. When the ear hook 3 is in the unlocked position, the locking portion 32 is located outside the buckling portion 202 in the left-right direction X to release the blocking of the locking portion 32 on the buckling portion 202, thereby releasing the clamping of the ear hook 3 on the docking card 200. The pushing portion 33 is received in the mounting groove 17 and is used to contact the bottom of the buckling portion 202. That is, when the buckling portion 202 downwardly abuts against the pushing portion 33, the ear hook 3 can be automatically rotated to the locking portion 32 to clamp the buckling portion 202 of the docking card 200. During the process of obliquely upwardly pulling out the side of the docking card 200 away from the ear hook 3, the pushing portion 33 upwardly pushes the buckling portion 202, enabling the buckling portion 202 to disengage from the card slot.

[0062] As Figure 3 shown, in any embodiment, the rotating shaft 34 is snapped into the rotating shaft hole 161 through the guiding groove 162 in the left-right direction X, and the rotating shaft 34 is in rotational cooperation with the rotating shaft hole 161. Conventionally, the ear hook 3 is generally assembled to the mounting portion 10b in the up-down direction Z, while in this embodiment, the ear hook 3 is mounted to the mounting portion 10b in the left-right direction X. With such a setting, when the ear hook 3 is not completely switched to the unlocked position, when the operator pulls out the docking card 200, the ear hook 3 will not be pulled out upward together. That is, when the operator withdraws the docking card 200, a part of the locking portion 32 is still located above the buckling portion 202, such that when the docking card 200 is pulled out, its buckling portion 202 will pull the ear hook 3 out upward or move it upward, and then the operator needs to readjust or install the ear hook 3 again, resulting in a poor use effect for the operator.

[0063] As Figure 3 、 Figure 4 、 Figure 15 and Figure 16As shown, in any embodiment, the unlocking assembly includes a moving member 5 and two elastic members 4 abutting against the moving member 5 along the left-right direction X. The elastic member 4 is a spring, preferably a linear spring. Compared with the spring sheet 534 in the prior art, the spring has a larger elastic force and a larger compression stroke than the spring sheet 534 in the left-right direction X. The spring can give the moving member 5 a larger displacement and elastic force, thereby making it easier to push the ear buckle 3 to rotate and unlock, and also easier to push the heavier docking card 200. The elastic member 4 extends along the left-right direction X and is accommodated in the receiving groove 181 in a one-to-one correspondence. Compared with the upper end of the spring sheet 534 in the prior art, which is exposed to the air and easily touched by mistake and unstable to install, the elastic member 4 of this embodiment is accommodated in the receiving groove 181, and the elastic member 4 will not be touched by other objects. Specifically, the shape of the receiving groove 181 is cylindrical, which is adapted to the outer contour of the elastic member 4. In this way, the receiving groove 181 can limit the elastic member 4 in the circumferential direction of the elastic member 4 and prevent the elastic member 4 from bending when the force is unbalanced. The guide groove 162 and the shaft hole 161 are spaced apart from the receiving groove 181 in the front-to-back direction Y to prevent the ear button 3 from extending into the receiving groove 181 and blocking the elastic deformation and movement of the elastic member 4. The elastic member 4 is exposed by the notch 182 in the corresponding receiving groove 181. It can be understood that the width of the notch 182 in the front-to-back direction Y is relatively narrow, and the elastic member 4 cannot be separated from the receiving groove 181 from the notch 182. In this embodiment, the elastic member 4 is a linear spring with a large compression stroke and moderate elasticity, which ensures that the elastic member 4 has a suitable elastic force and can smoothly push the ear button 3 to unlock through its own restoring force. The spring is specifically selected according to the actual situation and is not limited here. In other embodiments, the elastic member 4 can also be other nonlinear springs.

[0064] like Figure 6 , Figure 8 as well as Figure 14 As shown, the movable member 5 includes an abutment portion 51, a connection portion 52 and an actuation portion 53 which are fixedly connected in sequence from left to right. The abutment portion 51 and the actuation portion 53 both protrude upward from the connection portion 52. The abutment portion 51 extends into the short groove 142 through the strip groove 131. The connection portion 52 is located in the strip groove 131, and the actuation portion 53 is located outside the strip groove 131.

[0065] like Figure 8 , Figure 11 as well as Figure 17 and Figure 20As shown, in any embodiment, the abutting portion 51 has a guiding inclined surface 511 which extends obliquely downward to the lower right from the upper end of the abutting portion 51. When the guiding portion 201 is inserted downward along the guiding inclined surface 511 into the slot 14, the guiding portion 201 abuts against the abutting portion 51, causing the abutting portion 51 to displace leftward and withdraw from the short slot 142 through the first through hole 121 so as to make way for the insertion of the guiding portion 201. Specifically, the height of the abutting portion 51 is higher than that of the connecting portion 52 and the actuating portion 53, and the top surface of the abutting portion 51 is closer to the top surface of the slot 14 than the bottom wall 13 in the up-down direction Z. Thus, when the guiding portion 201 is inserted downward into the slot 14, the guiding portion 201 can first abut against the guiding inclined surface 511, thereby driving the abutting portion 51 to move leftward, that is, the moving member 5 as a whole displaces leftward, so as to facilitate the actuating portion 202 to actuate the pushing portion 33 to rotate and lock the earhook 3.

[0066] As Figure 3 and Figure 5 shown, in the first embodiment, the moving member 5 is integrally formed by stamping a metal plate. The moving member 5 is mounted upward from the bottom wall 13 to the strip-shaped groove 131. Thus, the abutting portion 51 is made of metal, integrally formed with the actuating portion 53 and the connecting portion 52, and the guiding inclined surface 511 is also a surface made of metal.

[0067] As Figure 16 , Figure 17 and Figure 20 shown, in the second embodiment, the abutting portion 51 includes a metal core 512 and a coating portion 513 injection-molded outside the metal core 512. The metal core 512 is fixedly connected to one end of the connecting portion 52 far from the actuating portion 53, and the guiding inclined surface 511 is formed on the coating portion 513. Specifically, the metal core 512, the connecting portion 52 and the actuating portion 53 are integrally formed by stamping a metal plate, and the coating portion 513 is an insulating material injection-molded on the outer surface of the metal core 512. A through hole 5121 is provided on the metal core 512 to facilitate enhancing the connection strength between the insulating materials on the front and rear sides of the coating portion 513 on the metal core 512. It can be known that the abutting portion 51 in the first embodiment is the metal core 512 in the second embodiment, that is, the guiding inclined surface 511 in the first embodiment is formed on the metal core 512. Thus, when the docking card 200 is inserted, it will rub against the metal guiding inclined surface 511. Thus, after multiple insertions and extractions, wear marks will be left on the edge of the docking card 200, damaging the appearance of the docking card 200. In the second embodiment, the guiding inclined surface 511 is formed on the coating portion 513. Firstly, it increases the width of the guiding inclined surface 511 in the front-rear direction Y and can play a better guiding role when contacting the docking card 200. Secondly, the hardness of the guiding inclined surface 511 is smaller and it is not easy to scrape the docking card 200. In addition, compared with the first embodiment, the coating portion 513 can also increase the structural strength of the metal core 512. When the docking card 200 is inserted forcefully into the slot 14, the metal core 512 will not be skewed and affect the automatic unlocking process.

[0068] As Figure 17 and Figure 19 shown, in the second embodiment, a recessed area 5131 is concavely provided on both the front and rear sides of the covering portion 513. The recessed area 5131 corresponds to the contact portion 21 of the conductive terminal 2 in the up-down direction Z, so as to make way for the contact portion 21 of the conductive terminal 2 during the left-right movement of the abutting portion 51, and prevent interference between the front and rear sides of the covering portion 513 and the contact portion 21 of the conductive terminal 2, thereby affecting the signal transmission performance of the contact portion 21 of the conductive terminal 2.

[0069] As Figure 19 and Figure 20 shown, in the second embodiment, the covering portion 513 is located above the connecting portion 52 and is set at a distance from the bottom wall surface of the slot 14. In this way, during the left-right movement of the moving member 5, the covering portion 513 will not interfere with the bottom wall surface of the slot 14 and hinder the movement of the moving member 5.

[0070] As Figure 20 shown, in the second embodiment, after the docking card 200 is inserted downward into the slot connector 100, the guiding portion 201 is inserted into the slot 14, the locking portion 202 is received in the installation groove 17 and is latched by the latching portion 32, and the extending portion 203 is located outside the slot 14 and is spaced from the covering portion 513 in the left-right direction X. That is, the left side of the metal core 512 is not covered by the covering portion 513. In this way, compared with the first embodiment, the thickness of the left side surface of the abutting portion 51 is not increased, thereby avoiding interference between the covering portion 513 and the extending portion 203. In other embodiments, the covering portion 513 may also cover the left side of the metal core 512, as long as it is spaced from the extending portion 203 in the left-right direction.

[0071] As Figure 16 、 Figure 19 and Figure 21 shown, in the second embodiment, due to the setting of the covering portion 513, the width of the abutting portion 51 is increased. Therefore, a through hole 134 is provided on the bottom wall 13 for the covering portion 513 to pass through, so that the covering portion 513 protrudes upward through the through hole 134 into the slot 14, and the moving member 5 is installed in place by moving in the left-right direction X toward the left end wall 12a.

[0072] As Figure 8 、 Figure 9 、 Figure 14 as well as Figure 20 and Figure 21As shown, in any embodiment, the connecting portion 52 is received in the strip-shaped groove 131, and includes an intermediate section 521 extending in the left-right direction X, and a first section 522 and a second section 523 connected to the left and right ends of the intermediate section 521 respectively. The first section 522 is connected between the abutting portion 51 and the intermediate section 521, and the second section 523 is connected between the intermediate section 521 and the actuating portion 53. Specifically, the first section 522 and the second section 523 protrude relatively from the intermediate section 521, and both the first section 522 and the second section 523 are exposed in the insertion slot 14 through the strip-shaped groove 131, and the bottom wall 13 blocks the intermediate section 521 downward. The first section 522 is provided with a blocking portion 5221 protruding downward, and the blocking portion 5221 is located on the left side of the first fixing member 6. During the process of the moving member 5 moving rightward to push the ear hook 3 to the unlocking position by the pushing portion 532, the blocking portion 5221 is blocked by the first fixing member 6, so as to prevent the abutting portion 51 from being displaced rightward too much, resulting in the need to manually adjust the position of the abutting portion 51 when the docking card 200 is inserted again.

[0073] As Figure 5 , Figure 8 , Figure 11 and Figure 20 As shown, in any embodiment, the actuating portion 53 is disposed on the mounting portion 10b, and includes a pushing portion 532, a main body portion 531, two support arms 533 and a spring piece 534. The main body portion 531 is folded relative to the connecting portion 52 into a flat plate shape, and the main body portion 531 is disposed at the bottom of the receiving groove 181, that is, at the bottom of the ear hook 3. The pushing portion 532 is located between the second section 523 and the main body portion 531. The pushing portion 532 is used to push the abutting portion 33 when the docking card 200 is pulled out, so that the ear hook 3 rotates from the locked position to the unlocking position. The pushing portion 532 is higher than the connecting portion 52 and the main body portion 531, and lower than the abutting portion 51. Specifically, the pushing portion 532 will not be higher than the top surface of the abutting portion 33, that is, when the buckling portion 202 is received in the positioning groove 31, the pushing portion 532 will not interfere with the buckling portion 202 in the up-down direction Z.

[0074] As Figure 13 and Figure 17 As shown, in any embodiment, the pushing portion 532 includes a pushing surface 5321. The pushing surface 5321 is the end surface of the pushing portion 532 facing upward. The pushing surface 5321 pushes the abutting portion 33 rightward and upward on the left side of the pivoting portion. The pushing surface 5321 is set to gradually decrease in height from top to bottom and rightward. Specifically, the pushing surface 5321 is not a surface extending obliquely and straight, but an arc surface extending obliquely and curvedly from top to bottom. In other embodiments, the pushing surface 5321 may be a surface extending obliquely and straight.

[0075] As Figure 5 , Figure 10 , Figure 11 and Figure 16 , Figure 17As shown, in any embodiment, the support arm 533 is a cantilever structure, and the support arm 533 and the elastic member 4 abut against each other in the left-right direction X to promote the elastic deformation of the elastic member 4, and the support arm 533 extends into the receiving groove 181 through the notch 182. Specifically, the two support arms 533 are folded upright relative to the main body 531, and are respectively connected to the front and rear ends of the main body 531. The support arms 533 are arranged corresponding to the receiving groove 181, and each arm 533 includes a side plate portion 5331, a lap portion 5332 and a convex portion 5333. The side plate portion 5331 extends along the up-down direction Z and connects to the main body 531. The lap portion 5332 is formed by bending from the top of the side plate portion 5331, and the convex portion 5333 is convexly arranged On the left side of the side plate portion 5331, specifically, the size of the side plate portion 5331 in the up-down direction Z is larger than the size of the receiving groove 181, the top and bottom ends of the side plate portion 5331 enter the receiving groove 181 through the notch 182 and abut the elastic member 4, and the elastic member 4 is sleeved on the convex portion 5333 along the left-right direction X, so that the convex portion 5333 and the elastic member 4 cooperate with each other to avoid displacement of the elastic member 4, and at the same time limit the side plate portion 5331 from escaping from the receiving groove 181 through the notch 182 upward, and the overlapping portion 5332 overlaps the outer expansion portion 18 to support the entire side plate portion 5331, so that the side plate portion 5331 can stably move in the left-right direction X without escaping from the notch 182.

[0076] like Figure 8 , Figure 11 as well as Figure 17 and Figure 20 As shown, in any embodiment, the spring piece 534 is located below the ear button 3 and is located at the right end of the ear button 3 relative to the pushing portion 532. The spring piece 534 always maintains an abutment state with the pushing portion 33 in the up and down direction Z, giving an upward thrust to the bottom of the ear button 3, so that when the ear button 3 is in the locked position, the spring piece 534 can support the ear button 3 to prevent the locking portion 32 of the ear button 3 from being separated from the buckle portion 202 of the docking card 200 due to factors such as the vibration of the slot connector 100.

[0077] like Figure 3 , Figure 14 as well as Figure 16 and Figure 21As shown, in any embodiment, the moving member 5 is mounted to the insulating body 1 from bottom to top. During installation, first install the elastic member 4 into the receiving groove 181, then align the first section 522 with the left end of the strip-shaped groove 131 and the second section 523 with the right end of the strip-shaped groove 131. Subsequently, insert the moving member 5 upward into the strip-shaped groove 131. At this time, the abutting portion 51 protrudes into the short groove 142, the connecting portion 52 enters the strip-shaped groove 131, and the actuating portion 53 is located on the right side of the mounting portion 10b. Immediately move the moving member 5 to the left until it is assembled in place. At this time, the abutting portion 51 is supported by the bottom wall 13, the actuating portion 53 enters the mounting groove 17, and the support arm 533 is inserted into the receiving groove 181 and abuts against the elastic member 4. Finally, horizontally mount the ear hook 3 in the left-right direction X into the mounting groove 17. In other embodiments, it is also possible that the elastic member 4 is first sleeved on the convex portion 5333 and elastically abuts against the side plate portion 5331, and then when the moving member 5 moves to the left, the elastic member 4 and the convex portion 5333 are inserted into the receiving groove 181 together.

[0078] As Figure 3 , Figure 8 and Figure 16 and Figure 20 As shown, in any embodiment, both the first fixing member 6 and the second fixing member 7 are made of metal materials and are arranged at intervals in the left-right direction X. The first fixing member 6 is inserted upward from the bottom wall 13 into the anti-fooling portion 15, and the second fixing member 7 is inserted upward from the bottom wall 13 into the right end wall 12b. Moreover, both the first fixing member 6 and the second fixing member 7 are assembled to the insulating body 1 after the unlocking assembly is installed to the insulating body 1. The first fixing member 6 supports the first section 522 upward, and the second fixing member 7 supports the second section 523 upward, so as to ensure that the moving member 5 is stably supported. Specifically, the first section 522 can slide in the left-right direction X on the first fixing member 6, and the second section 523 can slide in the left-right direction X on the second fixing member 7.

[0079] As Figure 7 , Figure 8 and Figure 10 As shown, in any embodiment, before the docking card 200 is inserted into the socket connector 100, although the elastic member 4 abuts against the support arm 533 in the left-right direction X, at this time, the elastic member 4 is still in a natural state, or in a slightly compressed state but does not push the moving member 5 to displace. The whole abutting portion 51 is located in the short groove 142, the pushing portion 532 is located in the mounting groove 17 and abuts against the pushing portion 33, the ear hook 3 is in the unlocked position, and the elastic piece 534 abuts against the bottom of the ear hook 3 upward.

[0080] As Figure 8 , Figure 10 , Figure 11 , Figure 12 and Figure 20As shown, in any embodiment, during the process of inserting the docking card 200 downward into the socket connector 100, one side of the docking card 200 is displaced downward along the guiding inclined surface 511 and pushes the abutting portion 51 to be displaced away from the ear hook 3, that is, the guiding portion 201 is displaced downward and extends into the guiding inclined surface 511 of the socket 14 against the abutting convex, driving the abutting portion 51 to be displaced leftward, so that the abutting portion 51 exits the short slot 142 through the first through hole 121, and gives way to the guiding portion 201 to insert into the socket 14, driving the abutting portion 51, that is, driving the moving member 5 as a whole to be displaced leftward. At this time, the pushing portion 532 is displaced leftward, so that the pushing portion 532 gives way to the pushing portion 33, that is, the pushing portion 532 no longer abuts against the pushing portion 33, and the two support arms 533 are also displaced leftward and simultaneously press the elastic member 4 leftward. The elastic member 4 is elastically compressed and stores elastic force; the bottom of the other side of the docking card 200 touches the pushing portion 33, causing the ear hook 3 to automatically rotate until the locking portion 32 latches the docking card 200, that is, as the latching portion 202 is gradually received in the positioning groove 31, it presses the pushing portion 33 downward, causing the ear hook 3 to gradually rotate from the unlocking position to the locking position, and the elastic piece 534 is also displaced leftward but still abuts against the pushing portion 33 upward.

[0081] As Figure 8 and Figure 13 shown, in any embodiment, during the process of pulling out the docking card 200 obliquely upward, that is, during the process of pulling the left end of the guiding portion 201 obliquely upward relative to its right end from the socket 14, one side of the docking card 200 releases the abutting portion 51, and the moving member 5 moves toward the side close to the ear hook 3 under the restoring force of the elastic member 4, that is, the left end of the guiding portion 201 releases the abutting portion 51 to provide a space for the abutting portion 51 to enter the short slot 142. The elastic member 4 restores its deformation, and its restoring force drives the support arm 533 to be displaced rightward, that is, drives the moving member 5 as a whole to be displaced rightward. At this time, the pushing portion 532 pushes the pushing portion 33 rightward, driving the ear hook 3 to gradually rotate rightward from the locking position toward the unlocking position. When the locking portion 32 is just entirely located on the right side of the latching portion 202, that is, when the latching portion 202 is not blocked upward by the locking portion 32, the ear hook 3 is in the unlocking position. At this time, the operator can pull out the docking card 200 as a whole.

[0082] The socket connector 100 of the present invention has the following beneficial effects:

[0083] 1. The receiving grooves 181 are provided on the front and rear sides of the mounting portion 10b, so that the receiving grooves 181 and the mounting grooves 17 are arranged side by side in the front-rear direction Y. In this way, the length dimension of the insulating body 1 in the left-right direction X will not be increased, and when the socket connector 100 is mounted on the circuit board 300, the space for mounting electronic components on the circuit board 300 will not be occupied. At the same time, the elastic member 4 is received in the receiving groove 181, and the arm 533 of the moving member 5 correspondingly extends into the receiving groove 181 to abut against the elastic member 4. In this way, it is not only convenient for the installation of the elastic member 4, but also when the arm 533 actuates the elastic member 4, the elastic member 4 can be restricted so that it is not easily detached from the receiving groove 181. The elastic member 4 is a linear spring, which elastically compresses and elastically returns in the receiving groove 181 in the left-right direction X. In this way, compared with the shrapnel 534 structure in the prior art, the spring is easier to install and has a better elastic effect.

[0084] 2. The receiving grooves 181 are provided on both the front and rear sides of the mounting groove 17. Each receiving groove 181 houses an elastic member 4, and each elastic member 4 abuts against a corresponding arm 533 in the left-right direction X. With this arrangement, it is more conducive to ensuring the balance of the overall structure of the moving member 5, avoiding uneven unilateral force on the arm 533, and thus preventing the actuating portion 53 from tilting and rubbing against the respective wall surfaces of the mounting portion 10b.

[0085] 3. The shrapnel 534 is always in contact with the pushing portion 33 in the up-down direction Z, giving an upward thrust to the bottom of the ear hook 3, so that when the ear hook 3 is in the locked position, the shrapnel 534 can support the ear hook 3, preventing the locking portion 32 of the ear hook 3 from being detached from the engaging portion 202 of the docking card 200 due to factors such as vibration of the socket connector 100.

[0086] 4. The notch 182 extends in the left-right direction X to expose the elastic member 4. The arm 533 can extend into the receiving groove 181 along the notch 182 and abut against the elastic member 4. The setting of the notch 182 can, on the one hand, facilitate the extension of the arm 533, ensure the movement direction of the arm 533, and the arm 533 will not interfere with the inner wall surface of the receiving groove 181 during the left-right movement, avoiding jamming of the moving member 5. On the other hand, the length of the notch 182 can adjust the deformation amount of the elastic member 4, that is, when the arm 533 abuts against the end of the notch 182, the restoring force of the elastic member 4 is within a suitable compression range, avoiding excessive compression of the elastic member 4 and being unable to return to its original position, ensuring that the elastic member 4 always has a suitable elastic abutting force and improving the service life of the elastic member 4.

[0087] 5. Bend the support arm 533 to form a side plate portion 5331 and a lap portion 5332. The side plate portion 5331 extends into the receiving groove 181 through the notch 182 and abuts against the elastic member 4. The lap portion 5332 is located outside the notch 182 and overlaps the top wall of the receiving groove 181 to support the support arm 533. When the support arm 533 abuts against the elastic member 4 along the left-right direction X, the lap portion 5332 is blocked by the top wall of the receiving groove 181. This ensures that the side plate portion 5331 will not separate from the receiving groove 181 or deviate from the position of the notch 182 during movement, ensuring that the side plate portion 5331 always moves along the notch 182 and abuts against the same position of the elastic member 4. In this way, the position where the elastic member 4 is abutted by the side plate portion 5331 is subjected to more uniform force, making the displacement of the movable member 5 in the left-right direction X more stable, and the unlocking of the ear buckle 3 smoother, which is convenient for automatic unlocking.

[0088] 6. The elastic member 4 is sleeved on the convex portion 5333, and the convex portion 5333 can cooperate with the elastic member 4 to prevent the elastic member 4 from being offset and unable to push the movable member 5, that is, to ensure that the elastic member 4 abuts against the support arm 533 along the moving path of the movable member 5. In this way, it can be ensured that the compression and elastic recovery of the elastic member 4 can prompt the movable member 5 to move along the left and right direction X to ensure that the ear buckle 3 can switch smoothly between the unlocking position and the locking position.

[0089] 7. The actuating portion 53 needs to be installed below the mounting portion 10b, so the moving member 5 is installed to the insulating body 1 from bottom to top. The installation method is relatively simple and convenient for mechanical operation.

[0090] 8. The stopper 5221 can limit the movement of the movable member 5 in the left-right direction X, that is, when the docking card 200 is tilted and pulled out, the movable member 5 moves toward one side of the ear button 3 to the pushing portion 532 to push the ear button 3 to the unlocking position, and the ear button 3 releases the hold on the docking card 200. At this time, the first fixing member 6 blocks the stopper 5221, which can limit the movable member 5 from continuing to move to the right. This can avoid the movable member 5 from moving too much and then needing to adjust the position of the movable member 5 again when the docking card 200 is inserted again, resulting in the inability to automatically insert the card.

[0091] 9. Compared with the arrangement in which the entire strip groove 131 is connected to the slot 14, only the two ends of the strip groove 131 are upwardly penetrated through the slot 14, and the portion corresponding to the middle section 521 is not penetrated through the slot 14. This is beneficial to ensure the overall structural strength of the insulating body 1 and prevent the bottom of the insulating body 1 from breaking after the docking card 200 is inserted into the slot 14.

[0092] 10. The ear stud 3 is installed on the installation part 10b from top to bottom. By inserting the ear stud 3 into the installation part 10b from left to right, such a setting can prevent the docking card 200 from taking out the ear stud 3 when being pulled out upwards. That is, when the operator pulls out the docking card 200, part of the locking part 32 is still above the buckling part 202, so that when the docking card 200 is pulled out, its buckling part 202 will take out the ear stud 3 upwards or move it upwards, which requires the operator to adjust or install the ear stud 3 again, resulting in a poor use effect for the operator.

[0093] 11. The guiding inclined surface 511 is formed on the covering part 513. First, it increases the width of the guiding inclined surface 511 in the front-back direction Y, and can play a better guiding role when contacting the docking card 200. Second, the hardness of the guiding inclined surface 511 is smaller and it is not easy to scrape the docking card 200. In addition, compared with the first embodiment, the covering part 513 can also increase the structural strength of the metal core 512. When the docking card 200 is inserted into the slot forcefully, the metal core 512 will not be skewed to affect the automatic unlocking process.

[0094] 12. The covering part 513 is located above the connecting part 52, and the distance between it and the bottom wall surface of the slot 14 is set. In this way, during the left-right movement of the moving part 5, the covering part 513 will not interfere with the bottom wall surface of the slot 14 to hinder the movement of the moving part 5.

[0095] 13. A recessed area 5131 is recessed on both the front and rear sides of the covering part 513. The recessed area 5131 corresponds to the contact part 21 of the conductive terminal 2 in the up-down direction Z, so as to make way for the contact part 21 of the conductive terminal 2 during the left-right movement of the abutting part 51, and avoid interference between the front and rear sides of the covering part 513 and the contact part 21 of the conductive terminal 2, affecting the signal transmission performance of the conductive terminal 2.

[0096] 14. The docking card 200 includes a guiding connection part 201, an extension part 203 and a buckling part 202 located on the left and right sides of the guiding connection part 201. When the guiding connection part 201 is inserted into the slot 14, the guiding connection part 201 is in electrical contact with the contact part 21 of the conductive terminal 2. The buckling part 203 is received in the installation groove 17 and is held by the locking part 32. The extension part 203 is located outside the slot and is spaced from the covering part 513 in the left-right direction X. In this way, the abutting part 51 will not contact the extension part 203 after withdrawing from the slot 14, that is, the extension part 203 will not affect the movement of the abutting part 51.

[0097] 15. The strip-shaped groove 131 is used to accommodate the connecting portion 52 of the moving member 5, preventing the connecting portion 52 from extending beyond the bottom wall 13 and affecting the soldering of the conductive terminal 2 to the circuit board 300. The through hole 134 is used for the abutting portion 51 to extend upward into the slot 14. However, since the covering portion 513 increases the width of the abutting portion 51, the through hole 134 not only needs to penetrate the base portion 132 vertically but also needs to disconnect the connection between the partial partition 133 on the front and rear sides of the base portion 132 and the base portion 132, so as to facilitate the installation of the covering portion 513.

[0098] The above detailed description is only for the description of the preferred embodiments of the present invention, and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made by using the content of this creative specification and the drawings are included in the patent scope of this creation.
