Description

Technical Field

[0001] The invention belongs to the technical field of electronic equipment structures, and in particular relates to a low-stub effect slot connector. Background Art

[0002] The memory stick is an important computer component for storing data. As computers become more and more popular, the memory stick is tested more and more frequently, so the memory stick needs to be frequently installed and removed from the memory slot on the motherboard. There are elastic ear clips on both sides of the memory slot, which can clamp the memory stick and fix it on the motherboard.

[0003] When installing a memory stick, you need to first open the ear buckles at both ends of the memory slot outwards, and insert the memory stick into the memory slot with force until the ear buckles return to their original position and lock the memory stick. When removing the memory stick, you need to first open the ear buckles outwards with force, and the memory stick will pop out of the memory slot. At this time, after the memory stick is removed, the opening of the memory slot is exposed, and external dust can easily accumulate in the slot through its opening, thereby affecting the contact stability of the electrical connection terminals. When there is too much dust, it can also cause the memory to be unrecognizable.

[0004] At the same time, existing memory slots have a stub effect (Via Stub). The stub effect refers to the frequency resonance phenomenon caused by the stub part of the signal via during signal transmission, which can cause signal integrity problems. The stub effect occurs when the signal encounters an open branch part (Stub) during transmission, causing the signal to be diverted and reflected. These reflected signals will cancel out the original signal at a specific frequency, thereby affecting the quality and stability of the signal. Specifically, in the memory slot, the stub effect is mainly reflected in the electrical connection terminals, such as Figure 8 As shown, the electrical connection terminal usually has a first bend portion 1a and a second bend portion 1b, so as to form an electrical connection point 1c for electrically contacting the terminal of the memory stick between the first bend portion 1a and the second bend portion 1b, and the distance between adjacent electrical connection points is usually smaller than the width of the memory stick. During the insertion process of the memory stick, the electrical connection points 1c on both sides are stretched open to form a stable electrical contact under the action of elasticity. However, in order to avoid the memory stick from contacting the end of the second bend portion 1b during insertion (if direct contact will cause the electrical connection terminal to be deformed by force), the second bend portion 1b is usually designed to be longer, and the second bend portion 1b is inserted upside down into the side wall of the memory slot to form a Pre load to cooperate with the inner wall of the slot to avoid the end of the second bend portion 1b from slipping out of the inner wall of the memory stick slot, resulting in a larger length of the second bend portion 1b to form a larger stump. This type of electrical connection terminal has a larger stump effect. Summary of the invention

[0005] In view of the above-mentioned technical problems, the present invention provides a low stump effect slot connector to solve the problem of stump effect in existing slot connectors. The low stump effect slot connector can effectively reduce the stump effect, reduce resonance, and improve high-frequency signal transmission effects.

[0007] Furthermore, the low residual pile effect slot connector also includes ear buckles, protrusions are provided at both ends of the slot body, and the slot body is provided with the strip groove between the two protrusions. The number of the ear buckles is two, and the two ear buckles are respectively rotatably provided on the two protrusions, and the ear buckles can rotate back and forth between a locked position and an unlocked position. The two ends of the floating bar are respectively inserted into the bottom of the two ear buckles. When the ear buckle is in the locked position, the ear buckle is perpendicular to the strip groove, and the floating bar is located at the bottom of the strip groove, exposing the electrical connection point for electrical connection; when the ear buckle is rotated from the locked position to the unlocked position, the ear buckle rotates outward and drives the floating bar to rise, and the floating bar supports the electrical connection points on both sides.

[0008] Furthermore, a grounding weld pin is provided at the bottom of the slot body, and the top of the grounding weld pin is inserted into the bottom of the strip groove. The floating strip includes a metal strip and an insulating rubber layer covering the outside of the metal strip. The insulating rubber layer has an exposure hole for exposing the metal strip at a position corresponding to the grounding weld pin. When the ear buckle is in the locked position, the metal strip is electrically connected to the grounding weld pin at the position of the exposure hole.

[0009] Furthermore, the ear buckle includes a strip portion, a top end and a bottom hook, the top end is located at the top of the strip portion, the bottom hook is located at the bottom of the strip portion, the strip portion is rotatably set on the protruding portion, the bottom hook is located in the strip groove, and a strip hole is set on the strip portion along the direction from the top end to the bottom hook, the two ends of the floating strip are respectively inserted into the strip holes of the two ear buckles, when the ear buckle is rotated from the locked position to the unlocked position, the top end of the ear buckle is deflected in the direction away from the protruding portion, and the bottom hook drives the floating strip to rise to the top of the strip groove, and the floating strip closes the top opening of the strip groove.

[0010] Furthermore, a through slot is formed on a side of the protruding portion facing away from the slot body, and the ear buckle is rotatably disposed in the through slot.

[0011] Furthermore, a clamping block is provided on the side wall of the strip-shaped portion, and a clamping slot is correspondingly provided on the side wall of the through slot. When the ear buckle is in the locking position, the clamping block is embedded in the clamping slot.

[0013] The low residual pile effect slot connector is used for the installation and fixation of a memory stick (or other similar electrical connection structures). It is provided with a floating bar that can change the floating position. Specifically, in the initial state, the floating bar stretches the electrical connection points on both sides. When the memory stick is inserted, the bottom end of the memory stick abuts the floating bar and drives the floating bar to descend to the bottom of the strip groove, and the electrical connection point is electrically connected to the memory stick; when the memory stick needs to be taken out, the floating bar rises to stretch the electrical connection points on both sides. Through this arrangement, the electrical connection points on both sides can be kept in an expanded state when the memory stick is not inserted, thereby avoiding the memory stick from directly abutting the end of the second bending portion when the memory stick is inserted, avoiding deformation of the electrical connection terminal. At the same time, compared with the existing slot structure, this arrangement can reduce the length design of the second bending portion, thereby reducing the low residual pile effect and improving the high-frequency signal transmission effect.

[0023] The invention discloses a low stump effect slot connector, which can effectively reduce the stump effect, lower the resonance, and improve the high-frequency signal transmission effect.

[0024] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the present invention. Obviously, what is described is only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figures 1 to 7As shown, the present invention discloses a low residual pile effect slot connector, including a floating strip 5 and a slot body 4, wherein the slot body 4 is provided with a strip groove 3, wherein the floating strip 5 can be floated up and down in the strip groove 3, and the two side walls of the strip groove 3 are provided with a plurality of electrical connection terminals 17; the electrical connection terminals 17 include a fixing portion 18, a first bending portion 19 and a second bending portion 20, wherein the fixing portion 18, the first bending portion 19 and the second bending portion 20 extend in a direction away from the bottom of the strip groove 3 in sequence, wherein the fixing portion 18 is installed on the slot body 4, and the first bending portion 19 is provided on the two side walls of the strip groove 3. 9 is connected to the fixing portion 18, the other end of the first bending portion 19 is bent toward the central axis of the strip groove 3, one end of the second bending portion 20 is connected to the other end of the first bending portion 19, the other end of the second bending portion 20 is bent toward the central axis away from the strip groove 3, and the connection position between the first bending portion 19 and the second bending portion 20 is an electrical connection point 21; when the floating bar 5 sinks to the bottom of the strip groove 3, the electrical connection point 21 is exposed for electrical connection; when the floating bar 5 rises, the floating bar opens the electrical connection points 21 on both sides.

[0026] The present low residual pile effect slot connector is used for the installation and fixation of a memory stick (or other similar electrical connection structures), and is provided with a floating bar 5 that can change the floating position. Specifically, in the initial state, the floating bar 5 stretches the electrical connection points 21 on both sides. When the memory stick is inserted, the bottom end of the memory stick abuts the floating bar 5 and drives the floating bar 5 to descend to the bottom of the strip groove 3, and the electrical connection point 21 is electrically connected to the memory stick; when the memory stick needs to be taken out, the floating bar 5 rises to stretch the electrical connection points 21 on both sides; through this arrangement, the electrical connection points 21 on both sides can be kept in an expanded state when the memory stick is not inserted, thereby avoiding the memory stick from directly abutting the end of the second bending portion 20 when the memory stick is inserted, avoiding deformation of the electrical connection terminal 17, and at the same time, compared with the existing slot structure, this arrangement can reduce the length design of the second bending portion 20, thereby reducing the low residual pile effect and improving the high-frequency signal transmission effect.

[0027] The low residual pile effect slot connector also includes an ear button 1, and the two ends of the slot body 4 are provided with a protrusion 2, and the slot body 4 is provided with the strip groove 3 between the two protrusions 2. The number of the ear buttons 1 is two, and the two ear buttons 1 are respectively rotatably provided on the two protrusions 2, and the ear buttons 1 can rotate back and forth between the locked position and the unlocked position. The two ends of the floating bar 5 are respectively inserted into the bottom of the two ear buttons 1. When the ear button 1 is in the locked position, the ear button 1 is perpendicular to the strip groove 3, and the floating bar 5 is located at the bottom of the strip groove 3, exposing the electrical connection point 21 for electrical connection; when the ear button 1 is rotated from the locked position to the unlocked position, the ear button 1 rotates outward and drives the floating bar 5 to rise, and the floating bar 5 opens the electrical connection points 21 on both sides.

[0028] The rotation of the ear button 1 can drive the lifting bar 5 to rise and fall. When the memory stick is inserted, the lifting bar 5 drives the ear button 1 to rotate to the locked position. When the memory stick needs to be taken out, the ear button 1 is pressed to deflect it away from the protrusion 2. The lifting bar 5 is lifted by the lever action, driving the memory stick out of the strip groove 3. At the same time, the ear button 1 drives the lifting bar 5 to rise, stretching the electrical connection points 21 on both sides.

[0029] A grounding weld pin 13 is provided at the bottom of the slot body 4, and the top of the grounding weld pin 13 is inserted into the bottom of the strip groove 3. The floating strip 5 includes a metal strip 14 and an insulating adhesive layer 15 covering the outside of the metal strip 14. The insulating adhesive layer 15 has an exposure hole corresponding to the position of the grounding weld pin 13 for exposing the metal strip 14. When the ear buckle 1 is in the locked position, the metal strip 14 is electrically connected to the grounding weld pin 13 at the position of the exposure hole.

[0030] The floating bar 5 includes a metal bar 14 and an insulating rubber layer 15 coated on the outside of the metal bar 14. The insulating rubber layer 15 is used to avoid electrical connection between the floating bar 5 and the electrical connection terminal 17 and the memory bar. At the same time, when the memory bar is inserted, the metal bar 14 is electrically connected to the grounding solder pin 13 through the exposed hole position, so that a grounding member is formed between different electrical connection terminals 17 through the metal bar 14. The member is electrically connected to the ground wire of the system, forming the so-called "negative grounding". This helps to stabilize the circuit and can effectively reduce crosstalk, thereby improving the quality and integrity of high-frequency signals.

[0031] The ear buckle 1 includes a strip portion 9, a top end 7 and a bottom hook 12, the top end 7 is located at the top of the strip portion 9, the bottom hook 12 is located at the bottom of the strip portion 9, the strip portion 9 is rotatably set on the protruding portion 2, the bottom hook 12 is located in the strip groove 3, and a strip hole is set on the strip portion 9 along the direction from the top end 7 to the bottom hook 12, the two ends of the floating strip 5 are respectively inserted into the two strip holes of the ear buckle 1, when the ear buckle 1 is rotated from the locked position to the unlocked position, the top end 7 of the ear buckle 1 is deflected in the direction away from the protruding portion 2, and the bottom hook 12 drives the floating strip 5 to rise to the top of the strip groove 3, and the floating strip 5 closes the top opening of the strip groove 3.

[0032] When the memory stick is taken out, the ear buckle 1 drives the floating bar 5 to rise to the top of the strip groove 3, and the floating bar 5 closes the top opening of the strip groove 3, thereby ensuring the closed state of the strip groove 3 after the memory stick is pulled out, which can effectively avoid the deposition of dust in the strip groove 3 and improve the electrical contact stability.

[0033] A through slot 6 is formed on a side of the protruding portion 2 facing away from the slot body 4 , and the ear buckle 1 is rotatably disposed in the through slot 6 .

[0034] The side wall of the strip portion 9 is provided with a card block 10 , and the side wall of the through slot 6 is correspondingly provided with a card slot. When the ear buckle 1 is in the locking position, the card block 10 is embedded in the card slot.

[0035] The side wall of the strip portion 9 is provided with a rotating shaft 11 , and the side wall of the through slot 6 is correspondingly provided with a rotating hole, and the rotating shaft 11 is rotatably inserted into the rotating hole.

[0036] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
