Abstract

The present disclosure provides a pushing piece and an electrical connector. The pushing piece is used for being mounted to the inner wall of a chip positioning slot of a bottom plate of the electrical connector. The pushing piece comprises a piece body and a supporting part. The piece body is formed with a guide sliding hole used for guiding the piece body to be mounted to the inner wall of the chip positioning slot. The supporting part is fixed to the piece body. The supporting part is used for abutting against a chip clamping piece and sliding between a first supporting surface and a second supporting surface of the chip clamping piece. When the supporting part slides to the first supporting surface, the chip clamping piece abuts against the piece body. When the supporting part slides to the second supporting surface, the supporting part supports the chip clamping piece to be away from the piece body. The pushing piece can not only reduce the maintenance cost of the electrical connector, but also reduce the maintenance difficulty of the electrical connector.

Description

Technical Field

[0001] This disclosure relates to the technical field of electrical connectors, and in particular to a push plate and an electrical connector. Background Technology

[0002] Electrical connectors generally consist of a circuit board, a base plate, and a chip. The base plate is mounted and fixed on the circuit board, forming a chip positioning groove together with the circuit board. Conductive terminals protrude from the bottom of the chip positioning groove. The chip is installed within the chip positioning groove so that its contact area abuts against the conductive terminals and forms an electrical connection, as illustrated in prior art patent CN201336491Y. During the use of electrical connectors, the installation and removal of the chip is a critical step requiring highly careful operation. Because placing or removing the chip from the chip positioning groove can easily cause pressure on the chip, the conductive terminals on the circuit board can be damaged due to excessive pressure, significantly increasing the maintenance cost of the electrical connector. Therefore, users must be extremely careful when installing or removing the chip, greatly increasing the difficulty of chip replacement and consequently, the maintenance difficulty of the electrical connector. Utility Model Content

[0003] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a push plate and electrical connector with lower maintenance costs and lower maintenance difficulty.

[0004] The purpose of this disclosure is achieved through the following technical solution:

[0006] The wafer body has guide holes for guiding the wafer body to be installed on the inner wall of the chip positioning slot; the support portion is fixed to the wafer body; the support portion is used to abut against the chip clamping member and slide between the first support surface and the second support surface of the chip clamping member; when the support portion slides to the first support surface, the chip clamping member abuts against the wafer body; when the support portion slides to the second support surface, the support portion supports the chip clamping member to move away from the wafer body.

[0007] In one embodiment, the pusher plate further includes a pusher portion connected to the plate body to push the pusher plate to slide relative to the base plate.

[0008] In one embodiment, the pushing part is used to slide on the guide groove of the upper buckle when the upper buckle is opened and closed on the base plate.

[0009] In one embodiment, the pushing part includes a push rod and a fixing member, the push rod being connected to the fixing member, and the push rod being slidably connected to the guide groove when the upper buckle is opened and closed on the base plate.

[0010] In one embodiment, at least two of the sheet, the support, and the fastener are integrally formed structures; and / or,

[0011] The guide hole is an oblong hole; and / or

[0012] The number of guide holes is at least two, and the extension directions of the two guide holes are parallel to each other.

[0013] An electrical connector includes a base plate, a chip holder, and a push plate as described in any of the above embodiments; the base plate is used to mount and fix the chip on a circuit board, and the base plate is used to surround the conductive terminals of the circuit board to form the chip positioning groove; the chip holder is located in the chip positioning groove and connected to the base plate, and the chip holder is used to mount and fix the chip, so that when the chip holder abuts against the chip body, the chip abuts against the conductive terminal through the chip positioning groove; the chip holder has a first support surface and a second support surface, the first support surface extends to the second support surface, the distance between the first support surface and the chip body is greater than the distance between the second support surface and the chip body, and the support portion abuts against the chip holder and slides between the first support surface and the second support surface.

[0014] In one embodiment, a guide post is formed on one side of the base plate facing the push plate, and the guide post passes through the guide hole and is slidably connected to the plate body.

[0015] In one embodiment, the chip holder is provided with a guide ramp, and the first support surface extends to the second support surface via the guide ramp; and / or,

[0016] The chip clamping member has a lifting guide hole, and the guide limiting post is sequentially disposed in the guide hole and the lifting guide hole, so that the chip clamping member is slidably limited within the chip positioning groove; and / or

[0017] The sliding direction of the chip holder relative to the guide limiting post is at an angle to the sliding direction of the guide limiting post relative to the chip body.

[0018] In one embodiment, the outer peripheral wall of the guide limiting post is formed with a limiting flange, and the two sides of the chip body slide against the limiting flange and the base plate respectively, so that the chip body is limited to the inner wall of the chip positioning groove, and the hole wall of the guide hole slides against the outer peripheral wall of the guide limiting post.

[0019] In one embodiment, the electrical connector further includes an upper buckle, which includes a buckle plate portion and a pivot portion connected together. The pivot portion is rotatably connected to the base plate. The buckle plate portion is used to open and close in the chip positioning slot. When the buckle plate portion is closed in the chip positioning slot, it abuts against the side of the chip holder opposite to the chip body. A guide groove is formed on one side of the buckle plate portion facing the push piece. The guide groove is used to slide with the push portion of the push piece when the buckle plate portion is open and closed in the chip positioning slot.

[0020] In one embodiment, the angle between the extending direction of the guide groove and the plane where the base plate is located is 30° to 80°.

[0021] Compared with the prior art, this disclosure has at least the following advantages:

[0022] 1) The aforementioned pusher plate has guide holes formed on its body. These guide holes guide the plate to be installed on the inner wall of the chip positioning slot, so that the plate is not only installed on the inner wall of the chip positioning slot, but the relative position between the plate and the chip positioning slot is also adjustable. Furthermore, the support part is fixed to the plate body, abuts against the chip clamping member, and slides between the first support surface and the second support surface of the chip clamping member. When the support part slides to the first support surface, the chip clamping member abuts against the plate body. When the support part slides to the second support surface, the support part supports the chip clamping member to move away from the plate body.

[0023] 2) When placing or removing the chip in the chip positioning slot, the chip body slides relative to the base plate to the first preset position on the base plate along the guide direction of the guide hole. At this time, the chip body drives the support part to slide to the second support surface, so that the chip clamping part leaves the chip body. That is, the support part supports the chip clamping part to leave the base plate, thereby forming a clearance gap between the chip and the conductive terminal. This effectively prevents the phenomenon of mutual squeezing between the chip and the conductive terminal when the user places or removes the chip in the chip positioning slot. This avoids the phenomenon of damage or even destruction of the chip and conductive terminal due to excessive pressure on the conductive terminal, thereby greatly reducing the maintenance cost of the electrical connector.

[0024] When the chip is placed in the chip positioning slot, the chip body is slid relative to the base plate to the second preset position of the base plate along the guiding direction of the guide hole. At this time, the chip body drives the support part to slide to the first support surface, so that the chip clamping member abuts against the chip body. That is, the support part supports the chip clamping member to abut against the base plate so that the chip can abut against the conductive terminal and be electrically connected.

[0025] 3) The aforementioned push plate not only reduces the difficulty of chip replacement, but also avoids damage or even destruction of the conductive terminals of the chip and circuit board caused by squeezing the chip during chip installation, thereby greatly reducing the maintenance difficulty of the electrical connector.

[0038] To facilitate understanding of this disclosure, a more complete description will be given below with reference to the accompanying drawings, which illustrate preferred embodiments of the present disclosure. However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.

[0039] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0041] This application provides a pusher for mounting on the inner wall of a chip positioning slot in the base plate of an electrical connector. The pusher includes a body and a support portion. The body has a guide hole for guiding the body to be mounted on the inner wall of the chip positioning slot. The support portion is fixed to the body. The support portion abuts against a chip clamping member and slides between a first support surface and a second support surface of the chip clamping member. When the support portion slides to the first support surface, the chip clamping member abuts against the body. When the support portion slides to the second support surface, the support portion supports the chip clamping member to move away from the body.

[0042] The aforementioned pusher plate, due to the presence of guide holes in the plate body, guides the plate body to be installed on the inner wall of the chip positioning slot. This ensures that the plate body is not only installed on the inner wall of the chip positioning slot, but also that the relative position between the plate body and the chip positioning slot is adjustable. Furthermore, the support portion is fixed to the plate body, abuts against the chip clamping member, and slides between the first and second support surfaces of the chip clamping member. When the support portion slides to the first support surface, the chip clamping member abuts against the plate body; when the support portion slides to the second support surface, the support portion supports the chip clamping member away from the plate body. When a chip is placed or removed from the chip positioning slot, the plate body slides relative to the base plate along the guide direction of the guide holes to a first preset position on the base plate. At this time, the plate body drives the support portion to slide to the second support surface, causing the chip clamping member to leave the plate body. In other words, the support portion supports the chip clamping member away from the base plate, thereby enabling a connection to be formed between the chip and the conductive terminal. The clearance effectively prevents the chip from being squeezed between itself and the conductive terminals when the user places or removes the chip from the chip positioning slot. This avoids damage to the chip and conductive terminals due to excessive pressure, thus greatly reducing the maintenance cost of the electrical connector. When the chip is placed in the chip positioning slot, the chip body slides relative to the base plate along the guide direction of the guide hole to the second preset position on the base plate. At this time, the chip body drives the support part to slide to the first support surface, so that the chip clamping part abuts against the chip body. That is, the support part supports the chip clamping part to abut against the base plate, so that the chip can abut against the conductive terminals and make electrical connection. The aforementioned push plate not only reduces the difficulty of chip replacement, but also avoids damage to the chip and the conductive terminals of the circuit board due to chip squeezing during chip installation, thus greatly reducing the maintenance difficulty of the electrical connector.

[0043] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0044] like Figures 1 to 10 As shown, an embodiment of the electrical connector 10 includes a pusher 100, a base plate 200, and a chip holder 300. The base plate 200 is mounted and fixed on the circuit board 400 of the electrical connector 10, and the base plate 200 is used to surround the conductive terminals of the circuit board 400 to form a chip positioning groove 210. The chip holder 300 is located in the chip positioning groove 210 and connected to the base plate 200. The chip holder 300 is used to mount and fix the chip 500, so that when the chip holder 300 abuts against the chip body 110, the chip 500 abuts against the conductive terminals through the chip positioning groove 210. The chip holder 300 has a first support surface 310 and a second support surface 320, the first support surface 310 extending to the second support surface 320. The pusher 100 is used to be mounted on the inner wall of the chip positioning groove 210.

[0045] In one embodiment, the pusher 100 includes a body 110 and a support portion 120, with the support portion 120 fixed to the body 110. The body 110 has a guide hole 111 for guiding the body 110 to be installed on the inner wall of the chip positioning groove 210. In this embodiment, a guide limiting post 220 protrudes from the inner wall of the chip positioning groove 210. The guide limiting post 220 passes through the guide hole 111 and is slidably connected to the body 110, so that the body 110 is guided to be installed on the inner wall of the chip positioning groove 210. The support portion 120 abuts against the chip clamping member 300 and slides between the first support surface 310 and the second support surface 320 of the chip clamping member 300. When the chip body slides relative to the chip holder 300 through the guide hole 111; when the support portion 120 slides to the first support surface 310, the chip holder 300 abuts against the chip body 110; when the support portion 120 slides to the second support surface 320, the support portion 120 supports the chip holder 300 away from the chip body 110. In this embodiment, the support portion 120 is positioned towards the opening of the chip positioning groove 210, so that the support portion 120 abuts against the chip holder 300 more effectively.

[0046] The aforementioned electrical connector 10 and its pusher piece 100, because the piece body 110 has a guide hole 111, the guide hole 111 is used to guide the piece body 110 to be installed on the inner wall of the chip positioning groove 210, so that the piece body 110 is not only installed on the inner wall of the chip positioning groove 210, but also the relative position of the piece body 110 and the chip positioning groove 210 is adjustable. Furthermore, because the support part 120 is fixed to the piece body 110, the support part 120 abuts against the chip clamping member 300 and slides between the first support surface 310 and the second support surface 320 of the chip clamping member 300; when the support part 120 slides to the first support surface 310... When the chip clamp 300 abuts against the chip body 110, and the support portion 120 slides to the second support surface 320, the support portion 120 supports the chip clamp 300 to move away from the chip body 110, the chip 500 is placed or removed from the chip positioning slot 210, and the chip body 110 is slid relative to the base plate 200 to the first preset position of the base plate 200 along the guiding direction of the guide hole 111. At this time, the chip body 110 drives the support portion 120 to slide to the second support surface 320, so that the chip clamp 300 moves away from the chip body 110, that is, the support portion 120 supports the chip clamp 300 to move away from the base plate 200. This creates a clearance between the chip 500 and the conductive terminal, effectively preventing mutual squeezing between the chip 500 and the conductive terminal when the user places or removes the chip 500 from the chip positioning slot 210. This avoids damage to the chip 500 and the conductive terminal due to excessive pressure, thus significantly reducing the maintenance cost of the electrical connector 10. When the chip 500 is placed in the chip positioning slot 210, the chip body 110 slides relative to the base plate 200 along the guide direction of the guide hole 111 to the second preset position of the base plate 200. At this time, the support part 12... The chip 500 slides to the first support surface 310. At this time, the chip body drives the support part 120 to slide to the first support surface 310, so that the chip clamping member 300 abuts against the chip body 110. That is, the support part 120 supports the chip clamping member 300 to abut against the base plate 200, so that the chip 500 can abut against the conductive terminal and be electrically connected. The aforementioned pusher 100 not only reduces the difficulty of replacing the chip 500, but also avoids damage or even destruction of the conductive terminals of the chip 500 and the circuit board 400 due to squeezing the chip 500 during installation, thereby greatly reducing the maintenance difficulty of the electrical connector 10. Furthermore, the distance between the first support surface 310 and the wafer 110 is greater than the distance between the second support surface 320 and the wafer 110. Thus, when the support portion 120 slides to the first support surface 310, the chip clamp 300 abuts against the wafer 110; when the support portion 120 slides to the second support surface 320, the support portion 120 supports the chip clamp 300 to move away from the wafer 110.

[0047] It is understood that as the support portion 120 slides to different positions relative to the base plate 200 along with the wafer body, the sliding position of the support portion 120 relative to the chip holder 300 also varies, resulting in different contact positions between the support portion 120 and the chip holder 300. This causes the chip holder 300 to contact or move away from the wafer body 110, and consequently, to contact or move away from the base plate 200. When adjusting the sliding position of the wafer body 110 relative to the base plate 200, and simultaneously adjusting the sliding position of the support portion 120 relative to the chip holder 300, the push plate 10 can be pushed by a tool or other components of the electrical connector 10.

[0048] To better serve the driving force, such as Figures 2 to 5 As shown, in one embodiment, the pusher 100 further includes a pusher 130 connected to the body 110 to push the pusher 100 to slide relative to the base plate 200, so that the user can push the body 110 to slide relative to the base plate 200 by the pusher.

[0049] like Figures 5 to 10As shown, in one embodiment, the pushing part 130 is slidably connected to the guide groove 610 of the upper buckle 600 when the upper buckle 600 is open or closed on the base plate 200, so as to synchronously push the pushing part 130 when the upper buckle 600 is open or closed on the base plate 200. In one embodiment, the electrical connector 10 further includes the upper buckle 600, which is rotatably or slidably connected to the base plate 200. In this embodiment, the upper buckle 600 is rotatably connected to the base plate 200. When the upper latch 600 rotates away from the chip positioning slot 210, the upper latch 600 slides away from the pushing part 130 and pushes the pushing part 130 to drive the chip body 110 to slide relative to the base plate 200 along the guiding direction of the guide groove 610 to the first preset position of the base plate 200. This allows the chip body 110 to drive the support part 120 to abut against and support the second support surface 320. At this time, the chip body 110 drives the support part 120 to slide to the second support surface 320, causing the chip clamp 300 to leave the chip body 110. That is, the support part 120 supports the chip clamp 300 to leave the base plate 200, thereby forming a clearance gap between the chip 500 and the conductive terminal, effectively preventing the phenomenon of mutual squeezing between the chip 500 and the conductive terminal when the user places or removes the chip 500 into the chip positioning slot 210. Conversely, when the upper latch 600 rotates and closes onto the chip positioning groove 210, the upper latch 600 approaches the pushing part 130 and pushes the pushing part 130 to drive the chip body 110 to slide relative to the base plate along the guiding direction of the guide groove 610 to the second preset position of the base plate 200. At this time, the chip body 110 drives the support part 120 to slide to the first support surface 310, so that the chip clamp 300 abuts against the chip body, that is, the support part 120 supports the chip clamp 300 to abut against the base plate 200, so that the chip 500 can be electrically connected to the conductive terminal. This allows the user to push the chip body 110 relative to the chip clamp 300 by opening and closing the upper latch 600, so as to facilitate the user to install and remove the chip 500, thereby greatly improving the ease of use of the electrical connector 10.

[0050] like Figure 4 and Figure 10As shown, in one embodiment, the upper buckle 600 includes a buckle plate portion 620 and a pivot portion 630 connected together. The pivot portion 630 is rotatably connected to the base plate 200. The buckle plate portion 620 is used to open and close in the chip positioning groove 210. When the buckle plate portion 620 is closed in the chip positioning groove 210, it abuts against the side of the chip clamping member 300 away from the chip body 110. A guide groove 610 is formed on the side of the buckle plate portion 620 facing the push piece 100. The guide groove 610 is used to slide in connection with the push portion 130 of the push piece 100 when it is open and closed in the chip positioning groove 210. When the latching plate 620 drives the pivot 630 to rotate in a direction away from the base plate 200, the chip positioning slot 210 is opened, the guide groove 610 slides away from the pushing part 130, and the pushing part 130 is pushed to drive the chip body 110 to slide relative to the base plate 200 along the guiding direction of the guide groove 610 to the first preset position, so that the chip body 110 can drive the support part 120 to abut against and support the second support surface 320. At this time, the chip body 110 drives the support part 120 to slide to the second support surface 320, so that the chip clamp 300 leaves the chip body 110, that is, the support part 120 supports the chip clamp 300 to leave the base plate 200, thereby forming a clearance gap between the chip 500 and the conductive terminal, effectively preventing the phenomenon of mutual squeezing between the chip 500 and the conductive terminal when the user places or takes out the chip 500 into or out of the chip positioning slot 210. When the latching plate 620 drives the pivot 630 to rotate away from the base plate 200, it engages with the chip positioning groove 210. The guide groove 610 slides into the pushing part 130, and pushes the pushing part 130 to drive the chip body 110 to slide relative to the base plate 200 along the guiding direction of the guide groove 610 to the second preset position. At this time, the chip body 110 drives the support part 120 to slide to the first support surface 310, so that the chip clamping member 300 abuts against the chip body 110. That is, the support part 120 supports the chip clamping member 300 to abut against the base plate 200, so that the chip 500 can be electrically connected to the conductive terminal. This allows the user to push the chip body 110 relative to the chip clamping member 300 by opening and closing the latch 600, which facilitates the user's installation and removal of the chip 500, thereby greatly improving the ease of use of the electrical connector 10. In this embodiment, the latching plate 620 and the chip positioning groove 210 are arranged opposite to each other.

[0051] Furthermore, the snap-on portion 620 and the pivot portion 630 are integrally formed to improve the structural compactness of the upper snap 600.

[0052] like Figure 3 and Figure 9As shown, in one embodiment, the angle between the extending direction of the guide groove 610 and the plane where the base plate 200 is located is 30°~80°, so that the guide groove 610 can slide away from or into the push rod 131 better when the upper buckle 600 is opened and closed on the base plate 200, and the upper buckle 600 can slide better relative to the push part 130 during the rotational connection with the base plate 200, thereby adjusting the sliding position of the plate 110 relative to the base plate 200. In this embodiment, the angle between the extending direction of the guide groove 610 and the plane where the base plate 200 is located is 60°.

[0053] like Figure 5 and Figure 10 As shown, in one embodiment, the pushing part 130 includes a push rod 131 and a fixing member 132. The push rod 131 is connected to the fixing member 132. The push rod 131 is slidably connected to the guide groove 610 when the upper buckle 600 is open or closed on the base plate 200, so that the upper buckle 600 can push the chip body to slide better relative to the chip holder 300, thereby greatly improving the ease of use of the electrical connector 10. In this embodiment, there are two fixing members 132, which are arranged opposite to each other. The two ends of the push rod 131 are respectively connected to the two fixing members 132, making the structural strength of the pushing part higher.

[0054] like Figure 5 As shown, in one embodiment, at least two of the sheet 110, support portion 120, and fixing member 132 are integrally formed structures; that is, the sheet 110 and support portion 120 are integrally formed structures, or the sheet 110 and fixing member 132 are integrally formed structures, or the support portion 120 and fixing member 132 are integrally formed structures, or the sheet 110, support portion 120, and fixing member 132 are integrally formed structures, thereby improving the structural compactness of the push sheet 100. In this embodiment, the sheet 110, support portion 120, and fixing member 132 are integrally formed structures, making the structure of the push sheet 100 more compact.

[0055] like Figure 5 As shown, in one embodiment, the guide hole 111 is an oblong hole so that the chip body 110 can slide relative to the chip holder 300 and the base plate along the guiding direction of the guide hole 111.

[0056] In one embodiment, when the end of the support portion 120 abuts against the first support surface 310, the chip clamping member 300 can drive the chip 500 to approach and abut against the conductive terminal of the circuit board 400 along the guiding direction of the guide limiting post 220, thereby making the chip 500 electrically connected to the conductive terminal of the circuit board 400; when the end of the support portion 120 abuts against the second support surface 320, the chip clamping member 300 can drive the chip 500 away from the conductive terminal of the circuit board 400 along the guiding direction of the guide limiting post 220, so that a clearance gap can be formed between the chip 500 and the circuit board 400, effectively preventing the phenomenon of mutual squeezing between the chip 500 and the conductive terminal of the circuit board 400 when the user places the chip 500 in the chip positioning slot 210 or takes it out from it.

[0057] like Figure 3 and Figure 9 As shown, in one embodiment, a guide post 220 is formed on one side of the base plate 200 facing the push plate 100. The guide post 220 passes through the guide hole 111 and is slidably connected to the plate body 110, allowing the plate body 110 to slide relative to the base plate 200. Further, the chip holder 300 has a lifting guide hole 330. The guide post 220 passes through the guide hole 111 and the lifting guide hole 330 in sequence, so that the chip holder 300 is confined within the chip positioning groove 210. The outer peripheral wall of the guide post 220 slides against the hole wall of the lifting guide hole 330, allowing the chip holder 300 to slide relative to the circuit board 400 in a direction closer to or further away. This allows the chip holder 300 to move the chip 500 closer to or further away from the conductive terminals of the circuit board 400 along the guiding direction of the lifting guide hole 330. In this embodiment, the sliding direction of the chip holder 300 relative to the guide limiting post 220 forms an angle with the sliding direction of the guide limiting post 220 relative to the wafer body 110. This angle adjusts the distance between the chip holder 300 and the base plate when the wafer body is slid by the pushing part, thereby adjusting the chip 500 to move closer to or further away from the conductive terminal. Specifically, the sliding direction of the chip holder 300 relative to the guide limiting post 220 is perpendicular to the sliding direction of the guide limiting post 220 relative to the wafer body 110.

[0058] like Figure 5 As shown, in one embodiment, there are at least two guide holes 111, and the extension directions of the two guide holes 111 are parallel to each other, so that the pusher 100 can move linearly along the guiding direction of the guide holes 111, ensuring the movement accuracy and stability of the pusher 100, preventing the pusher 100 from shifting or shaking during the movement relative to the chip holder 300, thereby greatly improving the stability of the electrical connector 10.

[0059] like Figure 9As shown, in one embodiment, the chip holder 300 is provided with a guide ramp 340, and the first support surface 310 extends to the second support surface 320 through the guide ramp 340, so that the support portion slides relatively smoothly between the first support surface 310 and the second support surface 320. When the support portion 120 abuts against the first support surface 310, the chip holder 300 can drive the chip 500 to approach and abut against the conductive terminal of the circuit board 400; while when the end of the support portion 120 abuts against the second support surface 320, the chip holder 300 can drive the chip 500 away from the conductive terminal of the circuit board 400, so that a clearance gap can be formed between the chip 500 and the circuit board 400, effectively preventing the phenomenon of mutual squeezing between the chip 500 and the conductive terminal of the circuit board 400 when the user places the chip 500 in the chip positioning slot 210 or removes it from it.

[0060] like Figures 2 to 3 As shown, in this embodiment, a connecting flange is formed on the inner wall of the chip positioning groove 210, and a guide limiting post 220 is formed on one side of the connecting flange facing the groove of the chip positioning groove 210. The chip body 110 is mounted on one side of the connecting flange facing the groove of the chip positioning groove 210 and slides against the connecting flange, so that the pusher 100 can more stably support the chip holder 300, thereby improving the stability of the use of the electrical connector 10.

[0061] Compared with the prior art, this disclosure has at least the following advantages:

[0062] 1) The aforementioned electrical connector 10, since the chip body 110 has a guide hole 111, the guide hole 111 is used to guide the chip body 110 to be installed on the inner wall of the chip positioning groove 210, so that the chip body 110 is not only installed on the inner wall of the chip positioning groove 210, but the relative position of the chip body 110 and the chip positioning groove 210 is adjustable. Since the support part 120 is fixed on the chip body 110, the support part 120 abuts against the chip clamping member 300 and slides between the first support surface 310 and the second support surface 320 of the chip clamping member 300; when the support part 120 slides to the first support surface 310, the chip clamping member 300 abuts against the chip body 110; when the support part 120 slides to the second support surface 320, the support part 120 supports the chip clamping member 300 to leave the chip body 110.

[0063] 2) When the chip 500 is placed or removed from the chip positioning slot 210, the chip body 110 is slid relative to the base plate 200 to the first preset position of the base plate 200 along the guiding direction of the guide hole 111. At this time, the chip body 110 drives the support part 120 to slide to the second support surface 320, so that the chip clamp 300 leaves the chip body 110. That is, the support part 120 supports the chip clamp 300 to leave the base plate 200, thereby forming a clearance gap between the chip 500 and the conductive terminal. This effectively prevents the phenomenon of mutual squeezing between the chip 500 and the conductive terminal when the user places or removes the chip 500 from the chip positioning slot 210. This avoids the phenomenon of damage or even destruction of the chip 500 and the conductive terminal due to excessive pressure, thereby greatly reducing the maintenance cost of the electrical connector 10.

[0064] When the chip 500 is placed in the chip positioning slot 210, the chip body 110 is slid relative to the base plate 200 to the second preset position of the base plate 200 along the guiding direction of the guide hole 111. At this time, the chip body 110 drives the support part 120 to slide to the first support surface 310, so that the chip clamping member 300 abuts against the chip body 110. That is, the support part 120 supports the chip clamping member 300 to abut against the base plate 200, so that the chip 500 can abut against the conductive terminal and be electrically connected.

[0065] 3) The aforementioned pusher 100 not only reduces the difficulty of replacing the chip 500, but also avoids damage or even destruction to the conductive terminals of the chip 500 and the circuit board 400 caused by squeezing the chip 500 during installation, thereby greatly reducing the maintenance difficulty of the electrical connector 10.

[0066] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
