Description

[Technical field]

[0001] The invention relates to a slot connector, in particular to a slot connector with a simple structure, convenient installation, reduced space occupation and an automatic card ejection function. [Background technology]

[0002] An existing slot connector is installed on a circuit board and is used for plugging and matching with a docking card. The electrical connector includes an insulating body extending longitudinally in the left-right direction. The insulating body includes a slot, a mounting portion, and an extension seat. The mounting portion and the extension seat are respectively arranged at the left and right ends of the slot. The 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 slot connector also includes an unlocking component. It includes an abutment portion, an elastic sheet and an actuating portion, the abutment portion is exposed in the slot, the elastic sheet and the actuating portion are located on an extension seat outside the slot, when the docking card is inserted into the slot, the docking card abuts against the abutment portion protruding into the slot, the abutment portion moves to allow the docking card to continue to be inserted into the slot, and squeezes the elasticity to cause it to deform; when the left end of the docking card is pulled obliquely upward from the slot relative to its right end, the docking card no longer abuts against the abutment portion, the elastic sheet recovers its deformation to drive the abutment portion to reset, and drives the actuating portion to actuate the ear buckle, so that the ear buckle rotates from the locked position to the unlocked position. However, since the insulating body is additionally provided with an extension seat along the left and right directions to receive the elastic sheet and the actuating part, the length of the original specification of the slot connector is increased, and when the connector is installed on the circuit board, it will occupy more space on the circuit board and block the installation of other electronic components; and the elastic sheet is formed by bending a metal sheet, and its elastic force is relatively small. For a heavier docking card, the elastic force of the elastic part is not enough to push the ear buckle to rotate; at the same time, the upper part of the extension seat is open, and the upward bent part of the elastic sheet is exposed outside the extension seat without being blocked, so the elastic sheet is not fixed stably and is easy to loosen or even fall off when touched.

[0003] Therefore, it is necessary to provide a slot connector with a simple structure, convenient installation, reduced space occupation and automatic card ejection function to overcome the above-mentioned defects. [Summary of the invention]

[0034] In order to facilitate a better understanding of the purpose, structure, characteristics and effects of the present invention, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods.

[0035] In the following description, unless otherwise specified, the directional words "up", "down", "left", "right", "front" and "back" are all based on the reference directions in the typical application environment of the present invention, that is, a main viewing angle is selected to determine the above directions. In the present invention, the left and right direction is defined as the X-axis direction, the front and back direction is defined as the Y-axis direction, and the up and down direction is defined as the Z-axis direction, wherein the rightward direction in the left and right direction X is the positive direction of the X-axis direction, the forward direction in the front and back direction Y is the positive direction of the Y-axis direction, and the upward direction in the up and down direction Z is the positive direction of the Z-axis direction. It can be understood that the directional positioning of the present invention is to better understand the relative position relationship and movement direction between the various components. In actual use, the directional positioning of the present invention can be adjusted according to the application environment. For example, the front and the back can be interchanged, the left and the right can also be interchanged, etc.

[0036] Reference Figures 1 to 14 As shown, the slot connector 100 of the present invention is used to be electrically connected to 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 slot connector 100, so as to transmit the electrical signal from the circuit board 300 to the slot connector 100, and then to the docking card 200. Specifically, the slot connector 100 is located above the circuit board 300, and the docking card 200 is plugged downward into the slot connector 100. Specifically, the slot connector 100 in this embodiment is specifically PCIE5.0, and of course it can also be other slot-type electrical connectors in other embodiments.

[0037] like Figure 1 and Figure 2 As shown, the docking card 200 is provided with a conductive portion 201 and a buckle portion 202 located on the right side of the conductive portion 201 along the left-right direction X. The conductive portion 201 and the buckle portion 202 are both located at the lower end of the docking card 200 and are spaced apart from each other in the left-right direction X. The conductive portion 201 is used to be electrically connected to the slot connector 100, and the buckle portion 202 is used to be buckled by the slot connector 100 to prevent the docking card 200 from detaching upward from the slot connector 100.

[0038] like Figure 2 and Figure 3As shown, the slot connector 100 includes an insulating body 1, a plurality of conductive terminals 2, an ear button 3, an unlocking component, a first fixing member 6 and a second fixing member 7. The plurality of conductive terminals 2 are provided on the insulating body 1. The ear button 3 is rotatably installed to one end of the insulating body 1. The ear button 3 has a locking position and an unlocking position relative to the insulating body 1. The unlocking component is installed to the slot connector 100 and is used to switch the ear button 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 to the insulating body 1 to fix the slot 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.

[0039] like Figure 6 and Figure 7 As shown, the insulating body 1 is made of insulating material, including an integrally formed plug-in portion 10a and a mounting portion 10b located on the right side of the plug-in portion 10a. Specifically, the mounting portion 10b is formed by protruding to the right from the plug-in portion 10a, and the bottom surface of the plug-in portion 10a is lower than the bottom surface of the mounting portion 10b in the up-down direction Z, and the width of the plug-in portion 10a is equal to the width of the mounting portion 10b in the front-to-back direction Y.

[0040] like Figure 2 and Figure 3 As shown, the plug-in portion 10a includes two side walls 11, a left end wall 12a, a right end wall 12b, a bottom wall 13 and an anti-mumbling portion 15. The two side walls 11 are arranged oppositely and spaced apart in the front-to-back direction Y, the left end wall 12a and the right end wall 12b are arranged oppositely 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, and the two side walls 11, the left end wall 12a and the bottom wall 13 jointly define a slot 14, and the slot 14 is used to receive the guide portion 201 of the docking card 200. The anti-mumbling portion 15 extends downward from the top surface of the plug-in portion 10a to the bottom wall 13, and divides the slot 14 into a long slot 141 and a short slot 142 along the left-right direction X, the short slot 142 is located between the left end wall 12a and the anti-mumbling portion 15, and the long slot 141 is located between the right end wall 12b and the anti-mumbling portion 15.

[0041] like Figure 7 , Figure 8 and Fig.13As shown, the bottom surface of the bottom wall 13 is concavely provided with a strip groove 131 extending along the left-right direction X. Both ends of the strip groove 131 in the left-right direction X penetrate upward through the bottom wall 13. Both ends of the strip groove 131 are connected to the long groove 141 and the short groove 142, respectively. Specifically, the strip groove 131 penetrates upward through the bottom wall 13 at the position adjacent to the fool-proofing portion 15 and the position adjacent to the right end wall 12b. The middle part of the strip groove 131 does not penetrate upward through the bottom wall 13, so that the connection strength of the bottom wall 13 can be guaranteed and the bottom wall 13 is prevented from breaking when the docking card 200 is inserted into the slot 14. It can be understood that in other embodiments, the middle part of the strip groove 131 can also penetrate upward through the bottom wall 13, or can penetrate upward through the bottom wall 13 discontinuously, as long as the two ends of the strip groove 131 penetrate upward through the bottom wall 13 and are connected to the long groove 141 and the short groove 142, respectively, and no specific limitation is made here.

[0042] like Fig.13 As shown, the left end wall 12a is provided with a first through hole 121 that passes through the left-right direction X, and the first through hole 121 is connected to the short groove 142. The right end wall 12b is provided with a second through hole 122 that passes through the left-right direction X and passes downward, and the second through hole 122 is connected to the long groove 141 and the strip groove 131. Specifically, the first through hole 121 and the second through hole 122 both extend along the up-down direction Z.

[0043] like Figure 4 and Fig.13 As shown, the mounting portion 10b includes two mounting walls 16 extending rightward from the outer surface of the right end wall 12b and two outward expansion portions 18. The two mounting walls 16 are opposite and spaced apart in the front-to-back direction Y. The two mounting walls 16 and the right end wall 12b enclose a mounting groove 17, and the mounting groove 17 is connected to the long groove 141 through the second through hole 122. The inner side surface of each mounting wall 16 is concavely provided with a guide groove 162 and a shaft hole 161 connected to the guide groove 162 along the left-right direction X. The guide groove 162 is located at a side away from the slot 14 relative to the shaft hole 161 and penetrates one end of the mounting wall 16 to the right along the left-right direction X. The guide groove 162 and the shaft hole 161 are spaced apart from the receiving groove 181 in the front-to-back direction Y. Specifically, the opening of the guide groove 162 is trumpet-shaped, parallel to the shaft hole 161 in the left-right direction X, and corresponding to the receiving groove 181 in the front-to-back direction Y.

[0044] like Figure 4 and Fig.14As shown, the two outward expansion parts 18 are respectively convexly arranged on the outer side surface of the mounting wall 16 and are located at the bottom of the mounting wall 16. The outward expansion part 18 is provided with a receiving groove 181 that penetrates the outward expansion part 18 to the right. The receiving groove 181 is isolated from the mounting groove 17. Specifically, each outward expansion part 18 is provided with a receiving groove 181. In other embodiments, a receiving groove 181 can also be provided on one side, which is not specifically limited here. The receiving groove 181 is arranged side by side with the guide groove 162 in the front-to-back direction Y. In this way, the receiving groove 181 is only provided on the front and back sides of the original mounting part 10b, and the length of the insulating body 1 in the left-right direction X will not be increased. When the insulating body 1 is installed on the circuit board 300, it is helpful to reduce the space occupied by the circuit board 300. The inner wall surface of the receiving groove 181 is provided with two notches 182 extending along the left-right direction X and penetrating the outward expansion part 18. The two notches 182 are formed by extending to the left 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-to-back direction Y, or in other directions, or one of the two notches 182 may be arranged on the inner wall surface of the receiving groove 181 along the up-down direction Z, and the other may be arranged on the inner wall surface of the receiving groove 181 along the front-to-back direction Y, which is not specifically limited here. At the same time, it can be understood that the number of notches 182 can also be selected according to actual conditions, and can be one or more.

[0045] like Figure 2 As shown, a plurality of conductive terminals 2 are arranged in two rows, front and back, and the two rows of conductive terminals 2 are respectively plugged upward from the bottom surface of the plug-in portion 10a to the two side walls 11. Each conductive terminal 2 includes a contact portion (not shown) exposed in the slot 14 along the front-to-back direction Y, a welding portion (not shown) protruding downward from the plug-in portion 10a, and a main body portion 531 (not shown) connected between the contact portion and the welding portion. The contact portion is used to contact the conductive portion 201 inserted into the slot 14 to achieve electrical connection between the slot connector 100 and the docking card 200. The welding portion is used to be welded to the circuit board 300 to achieve electrical connection between the slot connector 100 and the circuit board 300. The main body portion 531 is fixed to the corresponding side wall 11.

[0046] like Figure 3 , Figure 7 and Fig.10As shown, the ear button 3 is pivotally connected to the mounting portion 10b along the left-right direction X, and the ear button 3 is provided with a positioning groove 31 penetrating the ear button 3 along the left-right direction X, a locking portion 32 located above the positioning groove 31, a top clamping portion 33 located below the positioning groove 31, and two rotating shafts 34 located at the front and rear sides of the top clamping portion 33. The positioning groove 31 is used to receive the buckle portion 202, and the positioning groove 31 partially overlaps with the mounting groove 17. The locking portion 32 is used to stop the buckle portion 202 accommodated in the positioning groove 31 downward when the ear button 3 is in the locking position, so as to prevent the buckle portion 202 from detaching upward from the ear button 3. When the ear button 3 is in the unlocking position, the locking portion 32 is located outside the buckle portion 202 in the left-right direction X, so as to release the blocking of the buckle portion 202 by the locking portion 32, thereby releasing the buckling of the ear button 3 to the docking card 200. The top clamping portion 33 is received in the mounting groove 17 to contact the bottom of the buckle portion 202. That is, when the buckle portion 202 abuts downward against the top clamping portion 33, the ear buckle 3 can automatically rotate until the locking portion 32 holds the buckle portion 202 of the docking card 200. When the docking card 200 is pulled out tilted upward away from the side of the ear buckle 3, the top clamping portion 33 pushes the buckle portion 202 upward to disengage the buckle portion 202 from the slot.

[0047] like Figure 3 As shown, the shaft 34 is inserted into the shaft hole 161 through the guide groove 162 along the left-right direction X, and the shaft 34 is rotatably matched with the shaft hole 161. The traditional ear button 3 is generally assembled to the mounting portion 10b along the up-down direction Z, while the ear button 3 in this embodiment is installed to the mounting portion 10b along the left-right direction X. With this arrangement, when the ear button 3 is not completely switched to the unlocked position, the operator will not pull out the ear button 3 upward when pulling out the docking card 200, that is, when the operator pulls out the docking card 200, a part of the locking portion 32 is still located above the buckle portion 202, so that when the docking card 200 is pulled out, its buckle portion 202 pulls the ear button 3 upward or moves it upward, and the operator needs to adjust or install the ear button 3 again, which makes the operator's use effect poor.

[0048] like Figure 3 , Figure 4 as well as Fig.14As shown, 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.

[0049] like Figure 5 as well as Figure 7 As shown, the movable member 5 is made of an integrally stamped metal plate, and the movable member 5 is installed upward from the bottom wall 13 to the strip groove 131. The movable member 5 includes an abutment portion 51, a connecting portion 52 and an actuating portion 53 which are sequentially connected from left to right. The abutment portion 51 and the actuating portion 53 both protrude upward from the connecting portion 52, and the abutment portion 51 extends into the short groove 142 through the strip groove 131. The connecting portion 52 is located in the strip groove 131, and the actuating portion 53 is located outside the strip groove 131.

[0050] like Figure 7 and Fig.10As shown, the abutment portion 51 has a guide bevel 511, which extends obliquely from the upper end of the abutment portion 51 to the lower right thereof. During the process of the guiding portion 201 being inserted downward into the slot 14 along the guide bevel 511, the guiding portion 201 abuts against the abutment portion 51, so that the abutment portion 51 is displaced to the left and exits the short slot 142 through the first through hole 121 to make way for the guiding portion 201 to be inserted. Specifically, the height of the abutment portion 51 is higher than the connecting portion 52 and the actuating portion 53, and the top surface of the abutment portion 51 is closer to the top surface of the slot 14 relative to the bottom wall 13 in the up-down direction Z. In this way, when the guiding portion 201 is inserted downward into the slot 14, the guiding portion 201 can first abut against the guide bevel 511, thereby driving the abutment portion 51 to move to the left, that is, the moving member 5 is displaced to the left as a whole, so as to actuate the top clamping portion 33 of the buckle portion 202 to rotate the ear buckle 3 to lock the buckle.

[0051] like Figure 7 , Figure 8 and Fig.13 As shown, the connecting portion 52 is received in the strip groove 131, and includes a middle section 521 extending along the left-right direction X, and a first section 522 and a second section 523 connected to the left and right ends of the middle section 521, the first section 522 is connected between the abutting portion 51 and the middle section 521, and the second section 523 is connected between the middle section 521 and the actuating portion 53. Specifically, the first section 522 and the second section 523 are relatively protruding from the middle section 521, and the first section 522 and the second section 523 are both exposed to the insertion slot 14 through the strip groove 131, and the bottom wall 13 blocks the middle section 521 downward. The first section 522 is provided with a stopper 5221 protruding downward, and the stopper 5221 is located on the left side of the first fixing member 6. When the movable member 5 moves to the right until the pushing portion 532 pushes the ear buckle 3 to the unlocking position, the stopper 5221 is stopped by the first fixing member 6, thereby preventing the abutment portion 51 from shifting to the right too much, which requires manual adjustment of the position of the abutment portion 51 when the docking card 200 is inserted again.

[0052] like Figure 5 , Figure 7 and Fig.10 As shown, the actuating portion 53 is disposed on the mounting portion 10b, and includes a pushing portion 532, a main body portion 531, two supporting arms 533 and a spring sheet 534. The main body portion 531 is folded relative to the connecting portion 52 to form a flat plate. The main body portion 531 is disposed at the bottom of the receiving groove 181, that is, at the bottom of the ear buckle 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 top clamping portion 33 when the docking card 200 is pulled out, so that the ear buckle 3 rotates from the locked position to the unlocked 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 top clamping portion 33, that is, when the buckle portion 202 is received in the positioning groove 31, the pushing portion 532 will not interfere with the buckle portion 202 in the up and down direction Z.

[0053] like Fig.12 As shown, the pushing portion 532 includes a pushing surface 5321, which is the end surface of the pushing portion 532 facing upward. The pushing surface 5321 pushes the top clamping portion 33 to the right and upward on the left side of the pivoting portion. The pushing surface 5321 is gradually lowered from top to bottom to the right. Specifically, the pushing surface 5321 is not a surface extending obliquely and straightly, but an arc surface extending obliquely and curved from top to bottom. In other embodiments, the pushing surface 5321 can be a surface extending obliquely and straightly.

[0054] like Figure 5 , Fig. 9 and Fig.11 As shown, the support arm 533 is a cantilever structure. 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. 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. Each support 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. The convex portion 5333 is convexly arranged on the side plate portion The left side of 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 outward 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.

[0055] like Figure 7 and Fig.10 As shown, 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 top clamping 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 clamping portion 202 of the docking card 200 due to factors such as the vibration of the slot connector 100.

[0056] like Figure 3 and Fig.13As shown, the movable member 5 is installed to the insulating body 1 from bottom to top. During installation, the elastic member 4 is first installed to the receiving groove 181, and then the first section 522 corresponds to the left end of the strip groove 131, and the second section 523 corresponds to the right end of the strip groove 131. Then, the movable member 5 is inserted upward into the strip groove 131. At this time, the abutting portion 51 protrudes into the short groove 142, the connecting portion 52 enters the strip groove 131, and the actuating portion 53 is located on the right side of the mounting portion 10b. Then, the movable member 5 is moved to the left to be 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, the ear buckle 3 is horizontally installed to the mounting groove 17 along the left-right direction X. In other embodiments, the elastic member 4 may be firstly sleeved on the protrusion 5333 and elastically abutted against the side plate 5331 , and then when the moving member 5 moves to the left, the elastic member 4 and the protrusion 5333 are inserted into the receiving groove 181 together.

[0057] like Figure 3 and Figure 7 As shown, the first fixing member 6 and the second fixing member 7 are both made of metal materials and are spaced apart along the left-right direction X. The first fixing member 6 is inserted upward from the bottom wall 13 to the foolproof portion 15, and the second fixing member 7 is inserted upward from the bottom wall 13 to the right end wall 12b, and 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 along the left-right direction X on the first fixing member 6, and the second section 523 can slide along the left-right direction X on the second fixing member 7.

[0058] like Figure 6 , Figure 7 and Fig. 9 As shown, before the docking card 200 is inserted into the slot connector 100, although the elastic member 4 abuts against the support arm 533 in the left-right direction X, the elastic member 4 is still in a natural state, or a slightly compressed state but will not push the moving member 5 to move, the abutting portion 51 is entirely located in the short slot 142, the pushing portion 532 is located in the mounting slot 17 and abuts against the top clamping portion 33, the ear button 3 is in the unlocked position, and the spring piece 534 abuts against the bottom of the ear button 3 upward.

[0059] like Figure 7 , Fig. 9 , Fig.10 and Fig.11As shown, during the process of inserting the docking card 200 downward into the slot connector 100, one side of the docking card 200 moves downward along the guiding inclined surface 511 and pushes the abutting portion 51 to move toward the side away from the ear button 3, that is, the guiding portion 201 moves downward and abuts against the guiding inclined surface 511 protruding into the slot 14, driving the abutting portion 51 to move leftward, so that the abutting portion 51 exits the short slot 142 through the first through hole 121, and makes way for the guiding portion 201 to be inserted into the slot 14, driving the abutting portion 51, that is, driving the moving member 5 to move leftward as a whole, at this time, the pushing portion 532 moves leftward, so that the pushing portion 532 moves leftward. The movable portion 532 gives way to the top clamping portion 33, that is, the pushing portion 532 no longer abuts against the top clamping portion 33, and the two supporting arms 533 also move to the left and simultaneously press the elastic member 4 to the left, and the elastic member 4 is elastically compressed and accumulates elastic force; the bottom of the other side of the docking card 200 touches the top clamping portion 33, so that the ear buckle 3 automatically rotates to the locking portion 32 to hold the docking card 200, that is, as the locking portion 202 is gradually accommodated in the positioning groove 31 and presses the top clamping portion 33 downward, the ear buckle 3 gradually rotates from the unlocking position to the locking position, and the spring piece 534 also moves to the left but still abuts against the top clamping portion 33 upward.

[0060] like Figure 7 and Fig.12 As shown, in the process of pulling out the docking card 200 obliquely upward, that is, in the process of pulling the left end of the guiding portion 201 obliquely upward from the slot 14 relative to its right end, one side of the docking card 200 releases the abutting portion 51, and the movable member 5 moves toward the side close to the ear button 3 under the action of 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 space for the abutting portion 51 to enter the short groove 142, and the elastic member 4 recovers its deformation, and its restoring force drives the support arm 533 to move to the right, that is, drives the movable member 5 to move to the right as a whole. At this time, the pushing portion 532 pushes the top clamping portion 33 to the right, driving the ear button 3 to rotate gradually from the locking position to the right toward the unlocking position. When the locking portion 32 is just located on the right side of the buckle portion 202 as a whole, that is, the buckle portion 202 is not blocked upward by the locking portion 32, the ear button 3 is in the unlocking position, and the operator can pull out the docking card 200 as a whole.

[0061] The slot connector 100 of the present invention has the following beneficial effects:

[0062] 1. The receiving grooves 181 are arranged 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-to-back direction Y, so that the length dimension of the insulating body 1 along the left-right direction X will not be increased, and when the slot connector 100 is installed on the circuit board 300, the space for installing electronic components on the circuit board 300 will not be occupied. At the same time, the elastic member 4 is accommodated in the receiving groove 181, and the arm 533 of the moving member 5 extends into the receiving groove 181 to abut against the elastic member 4, so that it is not only convenient to install the elastic member 4, but also the arm 533 can limit the elastic member 4 while actuating the elastic member 4 so that it is not easy to leave the receiving groove 181. The elastic member 4 is a linear spring, which is elastically compressed and elastically restored in the receiving groove 181 along the left-right direction X. Compared with the spring sheet 534 structure in the prior art, the spring is easier to install and has a better elastic effect.

[0063] 2. Receiving grooves 181 are provided on both the front and rear sides of the mounting groove 17, and each receiving groove 181 accommodates an elastic member 4. Each elastic member 4 abuts against a corresponding support arm 533 in the left-right direction X. Such a configuration is more conducive to ensuring the balance of the overall structure of the moving member 5, and avoiding uneven force on one side of the support arm 533, which causes the actuating portion 53 to tilt and scrape against the various wall surfaces of the mounting portion 10b.

[0064] 3. The spring piece 534 always maintains an abutment state with the top clamping portion 33 in the up-down direction Z, giving an upward thrust to the bottom of the ear buckle 3, so that when the ear buckle 3 is in the locked position, the spring piece 534 can support the ear buckle 3 to prevent the locking portion 32 of the ear buckle 3 from being separated from the clamping portion 202 of the docking card 200 due to factors such as the vibration of the slot connector 100.

[0065] 4. The notch 182 extends along the left-right direction X to expose the elastic member 4, and the arm 533 can extend into the receiving groove 181 along the notch 182 and abut the elastic member 4. The setting of the notch 182 can facilitate the extension of the arm 533 to 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, thereby avoiding the moving member 5 from getting stuck. On the other hand, the length of the notch 182 can adjust the deformation 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, thereby avoiding excessive compression of the elastic member 4 and being unable to return to its original position, thereby ensuring that the elastic member 4 always has a suitable elastic holding force and improving the service life of the elastic member 4.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 10. Compared with the ear button 3 being installed on the mounting portion 10b from top to bottom, the ear button 3 is installed into the mounting portion 10b from left to right. This arrangement can prevent the ear button 3 from being pulled out when the docking card 200 is pulled out upward. That is, when the operator pulls out the docking card 200, a part of the locking portion 32 is still located above the buckle portion 202, so that when the docking card 200 is pulled out, the buckle portion 202 thereof pulls out or moves the ear button 3 upward, thereby requiring the operator to adjust or install the ear button 3 again, resulting in a poor use effect for the operator.

[0072] The above detailed description is only an explanation of the preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made by using the description and illustrations of this creation are included in the patent scope of this creation.
