Description
[Technical Field]
[0001] This utility model relates to a slot connector, and more particularly to a slot connector for stable ear clip installation. [Background Technology]
[0002] Existing card edge connectors for inserting electronic cards include an insulating body with a slot and an ear clip mounted to one end of the insulating body. One end of the insulating body has a mounting groove along the left-right direction. The inner wall of the mounting groove has a guide groove and a pivot hole sequentially arranged along the top-bottom direction. The guide groove is located directly above the pivot hole and extends upwards. The ear clip has a pivot portion corresponding to the pivot hole. The pivot portion is installed into the pivot hole from top to bottom through the guide groove. This allows the ear clip to rotate relative to the mounting groove. When the electronic card is inserted into the slot, the ear clip rotates to engage one side of the electronic card, preventing the electronic card from detaching upwards from the slot. It is understood that traditional... The shaft hole is generally circular, and the rotating shaft of the matching ear clip is also cylindrical. In order for the rotating shaft to enter the rotating shaft hole through the guide groove downwards, the upper wall of the rotating shaft hole usually needs to be partially extended upwards to connect with the guide groove. Therefore, the upper wall of the rotating shaft hole is broken, that is, the upper wall of the rotating shaft hole has a poor blocking effect on the rotating shaft in the vertical direction. Therefore, when the operator is in a hurry to pull the electronic card upwards, but one side of the electronic card has not completely detached from the ear clip, there is a risk that the ear clip will be pulled upwards by the electronic card, making the installation position of the ear clip unstable. It will also require the operator to manually adjust or reinstall the ear clip downwards when inserting the electronic card again.
[0003] Therefore, it is necessary to provide a slot connector that provides stable ear clip mounting to overcome the above-mentioned defects. [Utility Model Content]
[0004] In view of the problems in the background technology, the purpose of this utility model is to provide a slot connector with stable ear clip installation.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a slot connector for receiving a docking card, comprising: an insulating body having a mating surface, a slot for receiving the docking card being recessed downward from the mating surface; the insulating body having a mounting portion on one side of the slot in the left-right direction; the mounting portion having a mounting groove; the mounting groove having a transverse guide groove and a pivot hole on two opposing inner wall surfaces in the front-back direction; the depth of the pivot hole in the front-back direction being greater than the depth of the transverse guide groove in the front-back direction; the upper wall surface of the pivot hole defining a mating surface; the mating surface extending continuously in the left-right direction; the transverse guide groove extending obliquely in the left-right direction and penetrating the mounting portion towards the side away from the slot; the upper wall surface of the transverse guide groove being lower than the mating surface; the pivot hole extending obliquely in the left-right direction and penetrating the mounting portion towards the side away from the slot; the upper wall surface of the transverse guide groove being lower than the mating surface; the pivot hole extending obliquely in the left-right direction... The direction is connected to the transverse guide groove; multiple conductive terminals are exposed in the slot for docking with the docking card; an ear clip is pivotally connected to the mounting groove to hold the docking card when it is inserted into the slot. A pivot portion is provided on the front and rear sides of the ear clip. The pivot portion passes through the transverse guide groove in the left-right direction and is engaged with the pivot hole. The pivot portion includes a circular core portion and a protruding portion protruding from the side of the circular core portion away from the slot. The pivot portion is also provided with a stop surface corresponding to the mating surface. The stop surface is formed on the upper side of the protruding portion and extends continuously in the left-right direction. When the ear clip rotates to lock the docking card, the mating surface abuts against the stop surface in the up-down direction, thereby preventing the pivot portion from moving upward.
[0006] Furthermore, the stop surface is inclined outward and upward relative to the mounting groove in the front-back direction, and the mating surface is inclined inward and downward relative to the mounting groove in the front-back direction. When the ear buckle is rotated and locked, the stop surface and the mating surface are engaged with each other in the vertical direction.
[0007] Furthermore, the circular core portion is provided with a guide surface extending obliquely towards the pivot portion on the side near the slot in the left-right direction. The guide surface cooperates with the transverse guide groove in the left-right direction so that the pivot portion is engaged in the pivot hole.
[0008] Furthermore, the pivot portion is gradually expanded outward relative to the mounting groove in the front-back direction, and the pivot hole is gradually reduced inward relative to the mounting groove in the front-back direction. The pivot portion is inserted into the pivot hole to limit each other in the front-back direction.
[0009] Furthermore, the pivot hole is also provided with a first arc surface and a second arc surface connected to the left and right sides of the mating surface in the left-right direction. The first arc surface is closer to the slot in the left-right direction than the second arc surface. The first arc surface is rotatably engaged with the circular core portion, and the second arc surface is rotatably engaged with the protruding portion. The radius of the first arc surface to the axis of the pivot hole is smaller than the radius of the second arc surface to the axis of the pivot hole, and the arc length formed by the first arc surface is greater than the arc length formed by the second arc surface.
[0010] Furthermore, the conductive terminal is provided with a fixing part, a contact part extending from the upper end of the fixing part, and a welding part extending from the lower end of the fixing part. The fixing part is fixed to the insulating body, the contact part protrudes into the slot in the front-back direction, and the welding part is used to weld to the circuit board. The position of the contact part in the vertical direction is higher than the upper edge of the transverse guide groove.
[0011] Furthermore, the slot connector also includes an unlocking component disposed on the insulating body, the unlocking component being used to actuate the ear buckle to automatically rotate and open the ear buckle to unlock the docking card when the docking card is pulled out tilted upwards on the side away from the ear buckle.
[0012] Furthermore, the mounting portion is provided with a receiving groove located outside the mounting slot. The receiving groove is spaced apart from the corresponding transverse guide groove and the pivot hole in the front-back direction, and the receiving groove extends through one end of the mounting portion in the left-right direction. The ear clip includes a locking part and a top locking part. The locking part is used to hold the docking card, and the top locking part is used to push the docking card upward. The unlocking component includes a moving part and an elastic member that abuts against the moving part in the left-right direction. The elastic member extends in the left-right direction and is accommodated in the receiving groove. The moving part includes a contact part, an actuating part, and a connecting part integrally connecting the contact part and the actuating part. The contact part is exposed on the side of the slot away from the mounting portion. The contact part has a guide slope. The actuating part is mounted on the mounting portion. The actuating part includes a pushing part and a support arm. The pushing part is located on the mounting portion. The slot is used to push the ear buckle open, and the support arm abuts against the elastic element in the left-right direction; during the process of inserting the docking card downward into the slot, one side of the docking card moves downward along the guide slope and pushes the abutting part to move away from the ear buckle, causing the pushing part to move away from the ear buckle to make way for the top card part, the support arm presses against the elastic element to make the elastic element elastically store force, and the bottom of the other side of the docking card touches the top card part, causing the ear buckle to automatically rotate to the locking part to hold the docking card; during the process of tilting the docking card upward and pulling it out, one side of the docking card releases the abutting part, and the moving part moves towards the ear buckle under the restoring force of the elastic element, thereby causing the pushing part to push the ear buckle to rotate, so that the locking part of the ear buckle releases the locking part from the other side of the docking card.
[0013] This utility model also provides a slot connector for receiving a docking card, comprising: an insulating body including a slot and a receiving groove and a mounting groove disposed on one side of the slot in a left-right direction, the slot being provided for receiving the docking card, the receiving groove and the mounting groove being spaced apart from each other, the receiving groove being located outside the mounting groove in a front-back direction, the receiving groove being open in a left-right direction towards the side away from the slot, the mounting groove having a transverse guide groove and a pivot hole on two opposing inner walls in a front-back direction, the pivot hole being recessed to a greater depth than the transverse guide groove in a front-back direction, the upper wall of the pivot hole defining a mating surface, the mating surface extending continuously in a left-right direction, the transverse guide groove extending obliquely in a left-right direction and open towards the side away from the slot, the pivot hole communicating with the transverse guide groove in a left-right direction; a plurality of conductive terminals exposed in the slot for docking with the docking card; and an ear latch pivotally connected to the mounting groove, including a locking part for inserting the docking card. The slot holds the docking card. A pivot portion protrudes from both the front and rear sides of the ear clip. The pivot portion passes through the transverse guide groove in the left-right direction and engages with the pivot hole. The mating surface prevents the pivot portion from moving upwards in the up-down direction. The unlocking assembly includes a moving member and an elastic member that abuts against the moving member in the left-right direction. The elastic member extends in the left-right direction and is accommodated in the receiving groove. The moving member includes an abutment portion, an actuating portion, and a connecting portion integrally connecting the abutment portion and the actuating portion. The abutment portion is exposed on the side of the slot away from the mounting groove, the connecting portion is located below the slot, and the actuating portion is installed in the mounting groove. During the process of tilting the docking card upwards and pulling it out, one side of the docking card releases the abutment portion. Under the restoring force of the elastic member, the moving member moves towards the side closer to the ear clip, thereby driving the pushing portion to rotate the ear clip, causing the locking portion of the ear clip to release its hold on the other side of the docking card.
[0014] Furthermore, the mating surface is inclined inward and downward relative to the mounting groove in the front-back direction; the upper side of the pivot portion is provided with a stop surface corresponding to the mating surface, the stop surface extends continuously in the left-right direction, and the stop surface is inclined outward and upward relative to the mounting groove in the front-back direction; when the ear buckle rotates to lock the docking clip, the mating surface abuts against the stop surface face-to-face in the up-down direction, thereby preventing the pivot portion from moving upward.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] This invention arranges the transverse guide groove and the pivot hole side by side in the left-right direction, so that the pivot part of the ear clip can be installed into the pivot hole along the transverse guide groove in the left-right direction to pivotally engage with the pivot hole. Compared with the prior art, the upper wall of the pivot hole in this embodiment does not need to be through upward, that is, the continuously extended mating surface can better prevent the pivot part from moving upward, and can achieve face-to-face blocking, thus increasing the blocking area of the mating surface. Even if the operator is in a hurry to pull the docking clip upward, the pivot part will not disengage from the pivot hole even if it moves upward, thereby effectively reducing the risk of the ear clip being pulled upward with the docking clip, and making the stability of the ear clip relative to the mounting part better.

Detailed Implementation Methods
[0035] To facilitate a better understanding of the purpose, structure, features, and effects of this utility model, the present utility model will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0036] In this invention, the left-right direction is defined as the X-axis, the front-back direction as the Y-axis, and the up-down direction as the Z-axis. The rightward direction within the left-right direction is the positive direction of the X-axis, the forward direction within the front-back direction is the positive direction of the Y-axis, and the upward direction within the up-down direction is the positive direction of the Z-axis. It should be noted that in the description of this invention, the terms "up," "down," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, it should not be construed as a limitation of this invention.
[0037] like Figure 1 , Figure 2 , Figure 15 and Figure 16As shown, the slot connector 100 of this utility model is used for electrical connection with the mating card 200 and the circuit board 300, respectively. That is, the circuit board 300 is electrically connected to the mating card 200 through the slot connector 100 to transmit electrical signals from the circuit board 300 to the slot connector 100, and then to the mating card 200. The slot connector 100 is located above the circuit board 300, and the mating card 200 is inserted downwards into the slot connector 100. Specifically, the slot connector 100 in this embodiment is a PCIe 5.0 connector, but in other embodiments it can be other slot type 111 electrical connectors.
[0038] like Figure 1 , Figure 12 and Figure 15 As shown, the docking card 200 has a guide portion 201 and a latching portion 202 located on the right side of the guide portion 201 along the left-right direction X. The guide portion 201 and the latching 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 guide portion 201 is provided with gold fingers (not shown) for electrical connection with the slot connector 100. The latching portion 202 is used to be held by the slot connector 100 after the guide portion 201 is inserted into the slot connector 100 to prevent the docking card 200 from detaching from the slot connector 100 upwards.
[0039] like Figure 2 , Figure 4 and Figure 15 As shown, the slot connector 100 includes an insulating body 11, multiple conductive terminals 2, ear clips 3, a first fixing member 6, and a second fixing member 7. The multiple conductive terminals 2 are disposed on the insulating body 11. The ear clips 3 are rotatably mounted to one end of the insulating body 11, having an unlocked position and a locking position relative to the insulating body 11. The first fixing member 6 and the second fixing member 7 are mounted to the insulating body 11 to fix the slot connector 100 to the circuit board 300. In one embodiment, the slot connector 100 further includes an unlocking component. The unlocking component is installed in the slot connector 100 and automatically switches the ear clips 3 from the unlocked position to the locking position when the card is removed. That is, the unlocking component can automatically unlock the ear clips 3 by inserting or removing the docking card 200. After the unlocking component is installed, the first fixing member 6 and the second fixing member 7 are then installed upwards onto the insulating body 1 to support the unlocking component. Figure 15 and Figure 16 As shown, in another embodiment, the slot connector 100 may not be equipped with an unlocking component, that is, the ear clip 3 of the slot connector 100 needs to be manually turned to lock and unlock it.
[0040] like Figure 2 and Figure 15As shown, the insulating body 11 is made of insulating material and includes an integrally formed plug portion 10a and a mounting portion 10b located on the right side of the plug portion 10a. Specifically, the mounting portion 10b protrudes to the right from the plug portion 10a. In the vertical direction Z, the bottom surface of the plug portion 10a is lower than the bottom surface of the mounting portion 10b, while in the front-back direction Y...
[0041] like Figure 3 , Figure 5 and Figure 11 As shown, the insertion part 10a has a mating surface 11, and the mating surface 11 is recessed from top to bottom to form a slot 111. The slot 111 extends in the left-right direction X and is used to receive the guide part 201. The mounting part 10b does not extend beyond the mating surface 11 in the up-down direction Z. The mounting part 10b includes a mounting groove 12 and two mounting walls 13 extending to the right from the right end of the insertion part 10a. The two mounting walls 13 are opposite to each other and spaced apart in the front-back direction Y. The two mounting walls 13 and one end of the insertion part 10a enclose the mounting groove 12. The mounting groove 12 and the slot 111 are isolated from each other in the left-right direction X. Specifically, the mounting groove 12 has a transverse guide groove 131 and a pivot hole 132 on two opposing inner wall surfaces in the front-rear direction Y. The transverse guide groove 131 extends obliquely in the left-right direction X and penetrates the mounting portion 10b towards the side away from the slot 111. That is, the inner surface of each mounting wall 13 is recessed with a transverse guide groove 131 and a pivot hole 132. The transverse guide groove 131 extends obliquely in the left-right direction X and penetrates the mounting wall 13 to the right. Specifically, the upper edge of the transverse guide groove 131 is lower than the mating surface 11, and the pivot hole 132 communicates with the transverse guide groove 131 in the left-right direction X. Compared with the prior art where the guide groove is located above the pivot hole and penetrates the mounting wall 13 upwards, the structural strength of the mounting wall 13 in the vertical direction Z is relatively poor. In contrast, the transverse guide groove 131 in this embodiment is located on the right side of the pivot hole 132, which helps to enhance the structural strength of the mounting wall 13 in the vertical direction Z.
[0042] like Figure 3 , Figure 5 and Figure 9As shown, each pivot hole 132 is provided with a mating surface 1321, a first arc surface 1322, and a second arc surface 1323. The mating surface 1321 is formed on the upper wall surface of the pivot hole 132. The mating surface 1321 extends continuously in the left-right direction X and connects the first arc surface 1322 and the second arc surface 1323. The mating surface 1321 is used to prevent the ear clip 3 from moving upward. Specifically, the recess depth of the pivot hole 132 in the front-back direction Y is greater than the recess depth of the transverse guide groove 131 in the front-back direction Y. In the prior art, the upper wall surface of the pivot hole needs to be partially connected to the guide groove, resulting in the upper wall surface of the pivot hole being narrower in the front-back direction Y, and the blocking effect is poor. In contrast, the mating surface 1321 of this embodiment extends continuously in the left-right direction X and does not need to penetrate upward, so it can better prevent the ear clip 3 from moving upward, that is, the blocking effect is better.
[0043] like Figure 5 As shown, the first arc surface 1322 and the second arc surface 1323 are arranged opposite each other in the left-right direction X. The first arc surface 1322 is closer to the slot 111 than the second arc surface 1323. That is, the first arc surface 1322 is located on the left side of the mating surface 1321, and the second arc surface 1323 is located on the right side of the mating surface 1321. Specifically, the first arc surface 1322 and the second arc surface 1323 are formed around the same center P. The radius r1 of the first arc surface 1322 to the axis P of the pivot hole 132 is smaller than the radius r2 of the second arc surface 1323 to the axis P of the pivot hole 132, and the arc length formed by the first arc surface 1322 is greater than the arc length formed by the second arc surface 1323.
[0044] like Figure 2 and Figure 3 As shown, in one embodiment, the mounting portion 10b further includes two outwardly extending portions 14, which protrude from the outer side of the mounting wall 13 and are located at the bottom of the mounting wall 13, thus making the width of the mounting portion 10b equal to the width of the insertion portion 10a. Each outwardly extending portion 14 has a receiving groove 141 extending to the right through the outwardly extending portion 14. The receiving groove 141 is spaced apart from the transverse guide groove 131 and the pivot hole 132 in the front-rear direction Y, and the receiving groove 141 is arranged side by side with the transverse guide groove 131 in the front-rear direction Y. With this arrangement, the receiving groove 141 is only provided on the front and rear sides of the original mounting portion 10b, without increasing the length of the insulating body 11 in the left-right direction X, which helps to reduce the space occupied by the circuit board 300 when it is installed. Figure 15 and Figure 16 As shown, in another embodiment, the outer side of the mounting wall 13 may not be provided with the outward extension 14, so that the width of the mounting part 10b is smaller than the width of the insertion part 10a.
[0045] like Figure 2 , Figure 5 and Figure 15As shown, multiple conductive terminals 2 are arranged in two rows, one in front and one behind. The two rows of conductive terminals 2 are inserted into two insulating bodies 11 from the bottom surface of the main body 531. Each conductive terminal 2 includes a fixing part 21, a contact part 22 extending from the upper end of the fixing part 21, and a welding part 23 extending from the lower end of the fixing part 21. The fixing part 21 is fixed in the insertion part 10a. The contact part 22 is exposed in the slot 111 in the front-back direction Y, and is used to contact the gold fingers of the conductive part 201 to realize the electrical connection between the slot connector 100 and the docking card 200. The welding part 23 is exposed on the bottom surface of the insertion part 10a and is used to weld to the circuit board 300 to realize the electrical connection between the slot connector 100 and the circuit board 300. Specifically, the contact portion 22 is positioned higher than the upper edge of the transverse guide groove 131 in the vertical direction Z. That is, the transverse guide groove 131 is positioned near the bottom of the mounting portion 10b. In other embodiments, this configuration can reduce the height of the mounting portion 10b, making the height of the mounting portion 10b lower than the mating surface 111.
[0046] like Figure 2 , Figure 6 , Figure 8 , Figure 9 as well as Figure 15 As shown, the ear clip 3 is pivotally connected to the mounting groove 12 in the left-right direction X, and is used to hold the latching part 202 of the docking card 200 in the locked position. The ear clip 3 includes a positioning groove 31, a locking part 32, a top locking part 33, and two pivoting parts 34. The positioning groove 31 passes through the ear clip 3 and the upward-penetrating part of the ear clip 3 in the left-right direction X. The locking part 32 is located above the positioning groove 31, and the top locking part 33 is located below the positioning groove 31, with the locking part 32 located to the right of the top locking part 33. The pivoting parts 34 are provided on the front and rear sides of the top locking part 33. The positioning groove 31 is used to receive the latching part 202 when the guide part 201 is inserted into the slot 111. The positioning groove 31 partially overlaps with the mounting groove 12. The locking part 32 is used to block the latching part 202 received in the positioning groove 31 downward when the ear buckle 3 is in the locking position, so as to prevent the latching part 202 from disengaging upward from the ear buckle 3. When the ear buckle 3 is in the unlocked position, the locking part 32 is located outside the latching part 202 in the left-right direction X, so as to release the blocking of the latching part 202 by the locking part 32, thereby releasing the ear buckle 3 from the fastening of the docking card 200. The top latch 33 is received in the mounting groove 12 and is used to contact the bottom of the latch 202. That is, when the latch 202 abuts the top latch 33 downward, the ear buckle 3 can automatically rotate to the locking part 32 to hold the docking card 200. During the process of tilting the docking card 200 upward and pulling it out, the top latch 33 pushes the latch 202 upward, which can make the latch 202 disengage from the slot.
[0047] like Figure 8 and Figure 9As shown, the pivot part 34 is used to rotate and engage with the pivot hole 132 to switch the ear clip 3 between the unlocked position and the locked position. The pivot part 34 passes through the transverse guide groove 131 in the left-right direction X and is pivotally engaged with the pivot hole 132. Compared with the installation method of the rotating shaft part from top to bottom to the rotating shaft hole in the prior art, in this embodiment, the pivot part 34 is blocked from upward displacement in the vertical direction Z by the mating surface 1321 of the pivot hole 132. That is, when the operator pulls the card upward, the ear clip 3 will not be pulled out by the docking card 200, which is beneficial to the stability of the ear clip 3 installation.
[0048] like Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the pivot portion 34 is cam-shaped and includes a circular core portion 341 and a protruding portion 342 protruding from the side of the circular core portion 341 away from the slot 111. Specifically, the protruding portion 342 is further away from the slot 111 than the circular core portion 341. The circular core portion 341 is pivotally engaged with the first arc surface 1322, and the protruding portion 342 is pivotally engaged with the second arc surface 1323. The circular core portion 341 is provided with a guide surface 3412, which is formed on the outer surface of the circular core portion 341 in the front-rear direction Y. The guide surface 3412 extends obliquely towards the side of the circular core portion 341 closer to the slot 111. The guide surface 3412 is used to engage with the transverse guide groove 131 to guide the pivot portion 34 to engage with the pivot hole 132 in the left-right direction X. In this embodiment, since the volume of the core portion 341 is larger than the volume of the protruding portion 342, the protruding portion 342 is positioned on the right side of the core portion 341. This makes it easier for the core portion 341 to be guided and installed into the pivot hole 132, and also helps to increase the pivot area between the core portion 341 and the first arc surface 1322, so that the ear clip 3 can rotate more smoothly relative to the mounting portion 10b.
[0049] like Figure 6 , Figure 7 and Figure 9As shown, the pivot portion 34, corresponding to the mating surface 1321, also has a stop surface 343 that extends continuously in the left-right direction X. The stop surface 343 is formed on the upper side of the protruding portion 342, thus increasing the area of the stop surface 343 compared to the upper side of the cylindrical pivot portion. The stop surface 343 and the mating surface 1321 are mutually adapted. When the ear clip 3 rotates to the locking position, the stop surface 343 and the mating surface 1321 are in face-to-face contact in the vertical direction Z. This arrangement increases the holding force of the ear clip 3 relative to the mounting portion 10b in the vertical direction Z. Specifically, the stop surface 343 is inclined outward and upward relative to the mounting groove 12 in the front-rear direction Y, and the mating surface 1321 also extends outward and upward relative to the mounting groove 12 in the front-rear direction Y. Thus, the limiting method in which the two fit together in the vertical direction Z further increases the holding force of the ear clip 3 in the vertical direction Z.
[0050] like Figure 10 and Figure 11 As shown, the pivot portion 34 is gradually expanded outward relative to the mounting groove 12 along the front-rear direction Y, while the pivot hole 132 is gradually recessed inward relative to the mounting groove 12 along the front-rear direction Y. That is, both the pivot portion 34 and the pivot hole 132 are flared, which is different from the regular circles of the pivot portion and pivot hole in the prior art. With this arrangement, when the pivot portion 34 is inserted into the pivot hole 132, the two can limit each other in the front-rear direction Y. In other words, the pivot portion 34 is more difficult to disengage from the pivot hole 132 in the front-rear direction Y, which makes the ear clip 3 rotate more stably after installation.
[0051] like Figure 8 and Figure 9 As shown, during the process of switching the ear clip 3 from the unlocked position to the locked position, the round core portion 341 slides counterclockwise along the first arc surface 1322, and the protruding portion 342 slides counterclockwise along the second arc surface 1323, so that the stop surface 343 and the mating surface 1321 gradually approach each other and abut against the limit in the vertical direction Z. At this time, the ear clip 3 is in the locked position. During the process of switching the ear clip 3 from the locked position to the unlocked position, similarly, the round core portion 341 slides clockwise along the first arc surface 1322, and the protruding portion 342 slides clockwise along the second arc surface 1323, so that the abutting portion 51 and the mating surface 1321 gradually separate. At this time, the ear clip 3 is in the unlocked position. That is, this embodiment increases the blocking area in the vertical direction Z between the pivot portion 34 and the pivot hole 132 to enhance the blocking structure of the ear clip 3, so that the ear clip 3 can only rotate between the unlocked position and the locked position, ensuring that the ear clip 3 will not rotate too much and open excessively, causing the risk of the ear clip 3 breaking.
[0052] like Figure 4 , Figures 12 to 14As shown, the unlocking component is used to actuate the ear clip 3 to automatically rotate and open the docking card 200 when the docking card 200 is tilted upward on the side away from the ear clip 3. Compared with the slot connector 100 where the ear clip 3 is manually unlocked, the ear clip 3 in the slot connector 100 with the automatic unlocking component is more easily pulled out by the docking card 200. That is, when the unlocking component pushes against the ear clip 3, the ear clip 3 may not completely release the latch 202. Therefore, when the operator pulls the docking card 200 upward, the ear clip 3 is more likely to be pulled out along with it. Therefore, in the slot connector 100 with the automatic unlocking system, the ear clip 3 is installed in the mounting slot 12 in the left-right direction X, which can make the ear clip 3 installed more stably and there is no need to worry about the ear clip 3 coming off.
[0053] like Figures 2 to 3 as well as Figure 10 As shown, the unlocking assembly includes a movable member 5 and two elastic members 4 that abut against the movable member 5 in the left-right direction X. The elastic members 4 are springs, preferably linear springs. The elastic members 4 extend in the left-right direction X and are correspondingly housed in the receiving grooves 141. The elastic members 4 are housed in the receiving grooves 141 and will not be touched by other objects. Specifically, the shape of the receiving grooves 141 is cylindrical, which is adapted to the outer contour of the elastic members 4. In this way, the receiving grooves 141 can restrict the elastic members 4 in the circumferential direction and prevent the elastic members 4 from bending when the force is unbalanced. The transverse guide grooves 131 and the pivot holes are spaced apart from the receiving grooves 141 in the front-back direction Y to prevent the ear clip 3 from extending into the receiving grooves 141 and blocking the elastic deformation and movement of the elastic members 4. In this embodiment, the elastic members 4 are linear springs with a large compression stroke and moderate elasticity, which can ensure that the elastic members 4 have appropriate elastic force and can smoothly push the ear clip 3 to unlock through their own restoring force. The specific spring is selected according to the actual situation and is not limited here. In other embodiments, the elastic members 4 can also be other non-linear springs.
[0054] like Figure 2 , Figure 12 and Figure 14 As shown, the movable part 5 is integrally stamped from a metal sheet. The movable part 5 is installed from bottom to top onto the insulating body 11. The movable part 5 includes an abutment part 51, a connecting part 52, and an actuating part 53 connected sequentially from left to right. Both the abutment part 51 and the actuating part 53 protrude upward from the connecting part 52. The abutment part 51 protrudes upward into the slot 111. The connecting part 52 is located at the bottom of the insertion part 10a, and the actuating part 53 is located at the bottom of the mounting part 10b.
[0055] like Figure 12 and Figure 13As shown, the abutment portion 51 has a guide slope 511, which extends obliquely downward from the upper end of the abutment portion 51 to the right. During the process of the guide portion 201 being inserted downward into the slot 111 along the guide slope 511, the guide portion 201 abuts against the abutment portion 51, causing the abutment portion 51 to shift to the left and exit the left side of the slot 111, so as to make room for the insertion of the guide portion 201. Specifically, the height of the abutment portion 51 is higher than that of the connecting portion 52 and the actuating portion 53. The top surface of the abutment portion 51 is closer to the top surface of the slot 111 in the vertical direction Z relative to the bottom wall. This is so that when the guide portion 201 is inserted downward into the slot 111, the guide portion 201 can first abut against the guide slope 511, thereby driving the abutment portion 51 to move to the left, that is, the moving member 5 as a whole is displaced to the left, so as to actuate the top locking portion 33 of the latching portion 202 and cause the ear buckle 3 to rotate and lock.
[0056] like Figures 12 to 14 As shown, the actuating part 53 is provided in the mounting part 10b, which includes a pushing part 532, a main body 531, two support arms 533 and a spring piece 54. The main body 531 is folded into a flat shape relative to the connecting part 52. The main body 531 is located at the bottom of the receiving groove 141, that is, at the bottom of the ear buckle 3. The pushing part 532 is located between the connecting part 52 and the main body 531. The pushing part 532 is used to push the top locking part 33 when the docking card 200 is pulled out, so that the ear buckle 3 rotates from the locking position to the unlocking position. The pushing part 532 is higher than the connecting part 52 and the main body 531, and lower than the abutting part 51. Specifically, the pushing part 532 will not be higher than the top surface of the top locking part 33, that is, when the latching part 202 is received in the positioning groove 31, the pushing part 532 will not interfere with the latching part 202 in the vertical direction Z.
[0057] like Figures 12 to 14 As shown, the pushing part 532 includes a pushing surface 5321, which is the upward-facing end face of the pushing part 532. The pushing surface 5321 pushes against the top locking part 33 from the left side of the pivot part 34 to the right and upward. The height of the pushing surface 5321 gradually decreases from top to bottom and to the right. Specifically, the pushing surface 5321 is not a surface that extends obliquely in a straight line, but rather an arc surface that extends obliquely from top to bottom. In other embodiments, the pushing surface 5321 may be a surface that extends obliquely in a straight line.
[0058] like Figure 10 and Figure 14 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 cause the elastic member 4 to deform elastically. Specifically, both 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 provided in the receiving groove 141, and the support arms 533 enter the receiving groove 141 and abut against the elastic member 4.
[0059] like Figure 12 and Figure 13 As shown, the spring piece 54 is located below the ear clip 3, and the relative pushing part 532 is located at the right end of the ear clip 3. The spring piece 54 always maintains abutment with the top clip part 33 in the vertical direction Z, giving the bottom of the ear clip 3 an upward pushing force, so that when the ear clip 3 is in the locked position, the spring piece 54 can support the ear clip 3 and prevent the locking part 32 of the ear clip 3 from disengaging from the latching part 202 of the docking card 200 due to factors such as vibration of the slot connector 100.
[0060] like Figure 2 , Figure 12 and Figure 13 As shown, the movable part 5 is installed onto the insulating body 11 from bottom to top. During installation, the elastic member 4 is first installed into the receiving groove 141, and then the movable part 5 is inserted upward into the insulating body 11. At this time, the abutting part 51 protrudes into the slot 111, the connecting part 52 enters the bottom of the insulating body 11, and the actuating part 53 is located on the right side of the mounting part 10b. Then, the movable part 5 is moved to the left to assemble it into place. At this time, the abutting part 51 is supported by the bottom wall of the insulating body 11, the actuating part 53 enters the mounting groove 12, and the support arm 533 is inserted into the receiving groove 141 and abuts against the elastic member 4. Finally, the ear clip 3 is horizontally installed into the mounting groove 12 along the left-right direction X.
[0061] like Figure 2 and Figure 12 As shown, the first fixing member 6 and the second fixing member 7 are both made of metal and are spaced apart in the left-right direction X. The first fixing member 6 and the second fixing member 7 are both inserted upward into the insulating body 11. The first fixing member 6 and the second fixing member 7 are assembled into the insulating body 11 after the unlocking component is installed into the insulating body 11. The first fixing member 6 and the second fixing member 7 support the connecting part 52 upward to ensure that the moving part 5 is stably supported. Specifically, the connecting part 52 can slide in the left-right direction X on the first fixing member 6 and the second fixing member 7.
[0062] like Figure 12 and Figure 13As shown, during the process of tilting the docking card 200 upwards and pulling it out, that is, during the process of tilting the left end of the guide part 201 upwards from the slot 111 relative to its right end, the abutment part 51 is released on one side of the docking card 200. The moving part 5 moves towards the side closer to the ear buckle 3 under the restoring force of the elastic member 4. That is, the left end of the guide part 201 releases the abutment part 51 to provide space for the abutment part 51 to enter the slot 111. The elastic member 4 restores its deformation, and its restoring force drives the support arm 533 to move to the right, that is, drives the moving part 5 to move to the right as a whole. At this time, the pushing part 532 pushes the top card part 33 to the right, driving the ear buckle 3 to rotate from the locking position to the right towards the unlocking position. When the locking part 32 is just located on the right side of the latch part 202, that is, when the latch part 202 is not blocked upwards by the locking part 32, the ear buckle 3 is in the unlocking position. At this time, the operator can pull out the docking card 200 as a whole.
[0063] like Figure 15 and Figure 16 This is the second embodiment of the present invention. The parts identical to the first embodiment are: the slot connector 100 includes an insulating body 11, multiple conductive terminals 2, an ear loop 3, a first fixing member 6, and a second fixing member 7. The multiple conductive terminals 2 are disposed on the insulating body 11. The ear loop 3 is rotatably mounted to one end of the insulating body 11, having an unlocking position and a locking position relative to the insulating body 11. The first fixing member 6 and the second fixing member 7 are mounted to the insulating body 11 to fix the slot connector 100 to the circuit board 300. The difference between the second embodiment and the first embodiment is that: in the second embodiment, the slot connector 100 does not have an unlocking component, and the mounting portion 10b of the insulating body 11 does not have an expansion portion 14 for mounting the unlocking component. This means that the width of the mounting portion 10b is smaller than the width of the insertion portion 10a. Therefore, the first embodiment is suitable for a connector structure where the ear loop 3 automatically unlocks, while the second embodiment is suitable for a connector structure where the ear loop 3 is manually unlocked. Apart from this, all structures in the second embodiment are the same as those in the first embodiment. The structures in the second embodiment other than the unlocking component can refer to the first embodiment.
[0064] The beneficial effects of this utility model are as follows:
[0065] 1. In this utility model, the transverse guide groove 131 and the pivot hole 132 are arranged side by side in the left-right direction X, so that the pivot part 34 of the ear buckle 3 can be installed into the pivot hole 132 along the transverse guide groove 131 in the left-right direction X. Compared with the prior art, the upper wall of the pivot hole 132 in this embodiment does not need to be through upward, that is, the continuously extended mating surface 1321 formed can better prevent the pivot part 34 from moving upward, and can achieve face-to-face blocking, which increases the blocking area of the mating surface 1321. Even if the operator is in a hurry to pull out the docking card 200 upward, the pivot part 34 cannot be dislodged from the pivot hole 132 even if it moves upward, which can effectively reduce the risk of the ear buckle 3 being pulled out upward by the docking card 200, and make the stability of the ear buckle 3 relative to the mounting part 10b better. The stop surface 343 is formed on the upper side of the protruding portion 342 and extends continuously in the left-right direction X. This increases the contact area between the pivot portion 34 and the mating surface 1321. When the pivot portion 34 rotates to the locking position, the stop surface 343 is stopped by the mating surface 1321 in the vertical direction Z and the two are in face-to-face contact. This not only enhances the stopping structure of the ear clip 3 and the holding force of the ear clip 3 relative to the mounting portion 10b in the vertical direction Z, but also limits the rotation range of the pivot portion 34 in the pivot hole 132. This ensures that the ear clip 3 can only rotate between the unlocked position and the locking position, ensuring that the ear clip 3 will not rotate too much and open excessively, which could cause the ear clip 3 to break.
[0066] 2. The stop surface 343 is inclined outward and upward relative to the mounting groove 12 along the front-back direction Y, and the mating surface 1321 also extends outward and upward relative to the mounting groove 12 along the front-back direction Y. Thus, the limiting method in which the two fit together in the vertical direction Z can further increase the holding force of the ear buckle 3 in the vertical direction Z.
[0067] 3. The volume of the core portion 341 is larger than that of the protruding portion 342. The guide surface 3412 is formed on the core portion 342. When the pivot portion 34 is installed into the pivot hole 132, the core portion 341 is more easily guided into the pivot hole 132. The guide surface 3412 cooperates with the transverse guide groove 131 in the left-right direction X, which makes it easier for the pivot portion 34 to be installed into the pivot hole 132 in the left-right direction X.
[0068] 4. Compared with the cylindrical pivot and circular pivot hole in the prior art, the pivot part 34 is gradually expanded outward relative to the mounting groove 12 in the front-back direction Y, while the pivot hole 132 is gradually shrunken inward relative to the mounting groove 12 in the front-back direction Y. In this way, when the pivot part 34 is inserted into the pivot hole 132, the two can limit each other in the front-back direction Y. That is, the pivot part 34 is more difficult to disengage from the pivot hole 132 in the front-back direction Y. As a result, the ear buckle 3 can rotate more stably after installation, and the overall stability is higher.
[0069] 5. The radius r1 of the axis P from the first arc surface 1322 to the pivot hole 132 is smaller than the radius r2 of the axis P from the second arc surface 1323 to the pivot hole. Thus, the stop surface 343 extends longer in the left-right direction X, that is, the contact area of the stop surface 343 is larger. The arc length formed by the first arc surface 1322 is greater than the arc length formed by the second arc surface 1323. Thus, the pivot area between the core part 341 and the first arc surface 1322 is larger, so that the ear buckle 3 can rotate more smoothly relative to the mounting part 10b.
[0070] 6. The contact portion 22 is positioned higher than the upper edge of the transverse guide groove 131 in the vertical direction Z. That is, the transverse guide groove 131 is positioned near the bottom of the mounting portion 10b. This configuration can reduce the height of the mounting portion 10b, making the height of the mounting portion 10b lower than the mating surface 111, thereby reducing the overall height of the slot connector.
[0071] 7. When the unlocking component pushes against the ear clip 3, the ear clip 3 may not completely release the latch 202. When the operator pulls the docking card 200 upward, the mating surface 1321 can effectively prevent the docking card 200 from being pulled out of the ear clip 3. Therefore, it can be ensured that the ear clip 3 of the slot connector 100 with automatic unlocking function can be firmly held in the mounting slot 12, and there is no need to worry about the ear clip 3 being dislodged during automatic unlocking.
[0072] 8. Receiving grooves 141 are provided on the front and rear sides of the mounting part 10b, so that the receiving grooves 141, the transverse guide grooves 131, and the pivot holes 132 are arranged side by side in the front-rear Y direction. This increases the structural strength of the mounting groove 12 where the transverse guide grooves 131 and the pivot holes 132 are located, and does not increase the length of the insulating body 11 in the left-right X direction. When the slot connector 100 is installed on the circuit board 300, it will not occupy the space for electronic components on the circuit board 300. At the same time, the elastic member 4 is housed in the receiving groove 141, and the support arm 533 of the moving member 5 extends into the receiving groove 141 to abut against the elastic member 4. This not only facilitates the installation of the elastic member 4, but also restricts the elastic member 4 from detaching from the receiving groove 141 while the support arm 533 actuates the elastic member 4. The elastic member 4 is a linear spring, which is elastically compressed and elastically returned in the receiving groove 141 in the left-right X direction. This makes the spring easier to install and provides better elasticity.
[0073] The above detailed description is only a description of the preferred embodiment of this utility model and is not intended to limit the patent scope of this utility model. Therefore, all equivalent technical changes made using the content of this invention's specification and illustrations are included within the patent scope of this invention.
