Technical Field
[0001] The present invention relates to the technical field of connectors, and more specifically, to a PCIE connector. Background Art
[0002] At present, server products have been widely used in the Internet industry, financial industry, government departments and other scenarios, thanks to the high performance, high reliability and high stability of server products. The PCIE connector is an important slot on the server motherboard, and it is also a core component of the server's high-performance computing capabilities. The PCIE connector is a high-speed, serial, full-duplex, computer expansion bus standard that uses a high-speed differential bus and a point-to-point connection for communication between two devices. With the widespread use of PCIE connectors, the requirements for their signal integrity are getting higher and higher.
[0003] The high-frequency performance of PCIE connectors is mainly affected by signal integrity and signal loss. Impedance mismatch on the signal path, crosstalk of adjacent signal lines, power supply noise or ground loop problems make the connector's anti-crosstalk, anti-loss, stability and integrity unguaranteed.
[0004] In addition, when high-frequency signals pass through the PCIE connector, resonance is easily generated between the ground terminal and the signal terminal, resulting in signal distortion and large resonance, which in turn reduces product performance. The existing technology reduces resonance by adding a ground shield, but this method will increase production costs. Summary of the invention
[0005] The technical problem to be solved by the present invention is that the existing PCIE connector has poor product performance and high production cost. In view of the above defects of the prior art, a PCIE connector is provided.

[0017] Furthermore, the first contact end is provided with a first angle, and the first bending point and the second bending point constitute the first angle.
[0018] Furthermore, the terminal shoulder is arranged at the fourth bend and is located outside the plastic body.
[0019] Furthermore, the barb structure is arranged between the third bending point and the fourth bending point.
[0020] Furthermore, the barb structures are respectively arranged on both sides of the terminal and are staggered.
[0021] Furthermore, the protrusions are arranged at intervals on the bottom, and the horizontal height of the protrusions is greater than the horizontal height of the terminal shoulder.

DETAILED DESCRIPTION
[0046] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be described clearly and completely in combination with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are partial embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.
[0047] Please refer to the attached Figure 1-Figure 15 The present invention provides a PCIE connector, comprising a plastic body 110, a terminal 120, a card board 130, a slot 111 and a bottom 140, wherein the terminal 120 is disposed in the plastic body 110, the card board 130 is inserted into the slot 111 and is electrically connected to the terminal 120;
[0048] The slot 111 is provided with placement grooves 112 on both sides, and the terminal 120 is fixedly disposed in the placement grooves 112;
[0049] The terminal 120 includes a signal terminal 121 and a ground terminal 122;
[0050] The signal terminal 121 and the ground terminal 122 are arranged at intervals;
[0051] The placement slot 112 of the ground terminal 122 is provided with an opening 113;
[0052] The terminal 120 further includes a first contact end 123, a terminal shoulder 124 and a second contact end 125, and a plurality of bends 126 are provided between the first contact end 123 and the second contact end 125;
[0053] The terminal shoulder 124 is disposed between the first contact end 123 and the second contact end 125 , and the bottom 140 is provided with a protrusion 114 and is used to separate the terminal shoulder 124 ;
[0054] A barb structure 127 is further disposed between the first contact end 123 and the second contact end 125 . The barb structure 127 is fixedly connected to the plastic body 110 .
[0055] In this embodiment, a slot 111 is provided on the top of the plastic body 110, and placement slots 112 are provided on both sides of the slot 111. The terminal 120 includes a signal terminal 121 and a ground terminal 122. The terminal 120 is arranged in the placement slot 112, and the signal terminal 121 and the ground terminal 122 are arranged at intervals. An opening 113 is provided on one side of the placement slot 112 of the ground terminal 122, and the opening 113 is arranged in a rectangular shape between the top and the bottom 140 of the plastic body 110. The high-frequency sound insulation of the connector is often worse than the low-frequency sound insulation, and excessive crosstalk interference will affect its signal integrity and network performance. By opening a hole 113 at the placement slot 112 of the ground terminal 122, the signal terminal 121 and the ground terminal 122 are placed in different electromagnetic field environments to reduce the crosstalk interference of the terminal 120 and improve the high-frequency performance of the connector. The connector does not need to be equipped with a grounding device to solve the resonance problem, which reduces the cost of the connector.
[0056] The terminal 120 further includes a first contact end 123 , a terminal shoulder 124 and a second contact end 125 . A plurality of bends 126 are disposed between the first contact end 123 and the second contact end 125 . The bend 126 includes a first bend 1261, a second bend 1262, a third bend 1263, a fourth bend 1264 and a fifth bend 1265; the first bend 1261 and the second bend 1262 have the same bending direction, and are opposite to the bending direction of the third bend 1263, that is, the first bend 1261 and the second bend 1262 are bent toward the side close to the slot 111, and the third bend 1263 is bent toward the side away from the slot 111; the second bend 1262 is arranged on the side close to the third bend 1263, so that the first angle θ of the first contact end 123 is increased to disperse the stress of the first contact end 123, avoid brittle failure of the bend 126, and affect the performance of the terminal 120. A second bend 1262 is added between the first bend 1261 and the third bend 1263 to bring the terminal 120 of the first contact end 123 closer to the gold finger of the card insertion board 130, thereby effectively reducing the characteristic impedance at the terminal 120 of the first contact end 123 and improving the performance of the connector.
[0057] The terminal 120 is disposed in the placement groove 112 of the plastic body 110, the terminal shoulder 124 is disposed at the fourth bend 1264, and the terminal shoulder 124 and the fourth bend 1264 are located outside the plastic body 110, and the bottom 140 of the plastic body 110 is provided with a protrusion 114 for spacing the terminal shoulder 124. The protrusions 114 are arranged at intervals at the bottom 140 of the plastic body 110, and the horizontal height of the protrusions 114 is greater than the horizontal height of the terminal shoulder 124, so as to avoid the copper wires at the cross section of the terminal 120 being connected after processing, resulting in a short circuit in the connector.
[0058] A barb structure 127 is also provided between the first contact end 123 and the second contact end 125. The barb structure 127 is provided between the third bend 1263 and the fourth bend 1264, and the barb structure 127 is provided on both sides of the terminal 120 in a staggered manner. The barb structures 127 on the left and right sides of the terminal 120 are provided protruding from the terminal 120 body. When the terminal 120 and the plastic body 110 are assembled, the barb structures 127 on the left and right sides of the terminal 120 are embedded in the placement groove 112 of the plastic body 110, so that the connection between the terminal 120 and the plastic body 110 is more secure. The barb structure 127 is provided in a staggered manner, which reduces the interference stress between the terminal 120 and the plastic body 110, and avoids the interference stress from being concentrated in the same place, causing the plastic body 110 to deform, thereby affecting the service life of the connector.
[0059] When high-frequency signals pass through the PCIE connector, resonance is easily generated between the ground terminal 122 and the signal terminal 121, resulting in signal distortion and large resonance, thereby reducing product performance. The prior art reduces resonance by adding a ground shield, but this method will increase production costs.
[0060] Please refer to Figure 1 , Figure 4-Figure 6 The opening 113 is disposed between the slot 111 and the bottom 140 , and its shape corresponds to the ground terminal 122 .
[0061] In the specific implementation: a slot 111 is provided at the top of the plastic body 110, and placement slots 112 are provided on both sides of the slot 111. The terminal 120 is provided in the placement slot 112, and the terminal 120 includes a signal terminal 121 and a ground terminal 122. No opening 113 is provided at the placement slot 112 of the signal terminal 121, and an opening 113 is provided at the placement slot 112 of the ground terminal 122. The opening 113 is mainly provided between the slot 111 at the top of the plastic body 110 and the bottom 140, and the shape corresponds to the ground terminal 122. The placement slot 112 of the ground terminal 122 is provided with the opening 113, so that the signal terminal 121 and the ground terminal 122 are in different electromagnetic field environments to reduce the influence of resonance, and the production cost is low.
[0062] Please refer to Figure 7 , Fig.11 , Fig.12 , Fig.14 and Fig.15 The bend 126 includes a first bend 1261, a second bend 1262, a third bend 1263, a fourth bend 1264 and a fifth bend 1265. The first bend 1261, the second bend 1262 and the third bend 1263 are arranged on a side close to the first contact end 123, and the fourth bend 1264 and the fifth bend 1265 are arranged on a side close to the second contact end 125.
[0063] In specific implementation: the first bend 1261, the second bend 1262 and the third bend 1263 are arranged on one side close to the first contact end 123. The second bend 1262 is added between the first bend 1261 and the third bend 1263, and the first bend 1261 and the second bend 1262 have the same bending direction, so that the first angle θ of the first contact end 123 is increased to disperse the stress of the first contact end 123 and avoid brittle failure of the bend 126 of the first contact end 123 of the terminal 120; the first angle θ of the first contact end 123 is increased, so that the terminal 120 force arm of the first contact end 123 is closer to one side of the slot 111. When the card board 130 is inserted, the distance between the terminal 120 force arm of the first contact end 123 and the gold finger of the card board 130 is closer, which reduces the characteristic impedance at the terminal 120 force arm of the first contact end 123 and improves the performance of the connector.
[0064] Please refer to Figure 7 , Fig.11 and Fig.14 The first contact end 123 is provided with a first angle θ, and the first bending portion 1261 and the second bending portion 1262 form the first angle θ.
[0065] In specific implementation: the first contact end 123 is provided with a first angle θ, and the first angle θ is formed by the first bend 1261 and the second bend 1262. If the first angle θ is too small, when the first contact end 123 is inserted into the card board 130, the distance between the force arm of the terminal 120 of the first contact end 123 and the gold finger will be farther, so that the characteristic impedance of the first contact end 123 is increased. By adding the second bend 1262 between the first bend 1261 and the third bend 1263, and the bending directions of the first bend 1261 and the second bend 1262 are the same, the first bend 1261 and the second bend 1262 are bent toward the side close to the slot 111, the first angle θ of the first contact end 123 is increased, so that the first contact end 123 is closer to the gold finger when the card board 130 is inserted, the characteristic impedance of the force arm of the terminal 120 of the first contact end 123 is effectively reduced, and the high-frequency performance of the connector is improved. The characteristic impedance of the connector is reduced by adjusting the body of the terminal 120 , thereby reducing the cost of the connector.
[0066] Please refer to Figure 7 and Figure 10-12 The terminal shoulder 124 is disposed at the fourth bending portion 1264 and is located outside the plastic body 110 .
[0067] In a specific implementation, the fourth bend 1264 and the fifth bend 1265 are arranged at one side close to the second contact end 125, the terminal shoulder 124 is arranged at the fourth bend 1264, and the terminal shoulder 124 and the fourth bend 1264 are both located outside the plastic body 110. The bottom 140 of the plastic body 110 is provided with a protrusion 114 for spacing the terminal shoulder 124, so as to prevent the copper wires at the cross section of the terminal 120 from being connected after processing, resulting in a short circuit in the connector, which affects the performance and service life of the connector.
[0068] Please refer to Figure 11-Figure 12 The barb structure 127 is disposed between the third bending portion 1263 and the fourth bending portion 1264 .
[0069] In specific implementation: the third bend 1263 and the fourth bend 1264 of the terminal 120 are provided with a barb structure 127, and the barb structure 127 is staggered. When the barb structure 127 is symmetrically arranged on both sides of the terminal 120, during assembly, the interference stress between the barb structure 127 of the terminal 120 and the plastic body 110 is concentrated at the same place, which easily causes the plastic body 110 to warp. The barb structures 127 on the left and right sides of the terminal 120 are staggered one up and one down, so as to disperse the interference stress between the barb structure 127 and the plastic body 110, effectively avoid the warping of the plastic body 110, and extend the service life of the connector.
[0070] Please refer to Fig.12 The barb structures 127 are respectively disposed on both sides of the terminal 120 and are staggered.
[0071] In specific implementation: the barb structure 127 is arranged between the third bend 1263 and the fourth bend 1264, and the barb structure 127 is arranged on the left and right sides of the terminal 120, one above and one below, respectively, so as to disperse the interference stress between the barb structure 127 and the plastic body 110, and avoid the interference stress being concentrated together to cause deformation of the plastic body 110. The protruding width of the barb structure 127 on both sides of the terminal 120 is greater than the width of the terminal 120 body. During assembly, the barb structure 127 on the terminal 120 is squeezed with the inner wall of the placement groove 112, so that the inner wall of the placement groove 112 is temporarily deformed. When the terminal 120 and the placement groove 112 are assembled in place, the part of the inner wall of the placement groove 112 that is temporarily deformed recovers its deformation, so that the barb structure 127 on the terminal 120 is embedded in the inner wall of the placement groove 112 and is clamped and fixed with the placement groove 112.
[0072] Please refer to Figure 2 and Fig.10 The protrusions 114 are arranged at intervals on the bottom 140 , and the horizontal height of the protrusions 114 is greater than the horizontal height of the terminal shoulder 124 .
[0073] In a specific implementation: a protrusion 114 is provided at the bottom 140 of the plastic body 110, which is used to space the terminal shoulder 124 located at the bottom 140 of the plastic body 110, and is located on the outside of the plastic body 110. The height of the protrusion 114 is greater than the height of the terminal shoulder 124, so as to prevent the copper wires at the cross section of the terminal 120 from being connected after processing, resulting in a short circuit in the connector.
[0074] Please refer to Fig.13 and Fig.17 The plastic body 110 is provided with a fixing piece 150 for connecting and fixing with an external device. Both ends of the plastic body 110 are provided with a fixing piece groove 115 , and the fixing piece 150 is fixedly arranged in the fixing piece groove 115 by snapping.
[0075] In the specific implementation: the two ends of the plastic body 110 are provided with fixing plates 150 for connecting and fixing with an external device. The two ends of the plastic body 110 are provided with fixing plate grooves 115, and the two sides of the fixing plate groove 115 are provided with clamping holes 116. When the fixing plate 150 and the plastic body 110 are assembled, the elastic buckles 152 provided on the two sides of the fixing plate 150 are squeezed by the inner wall of the fixing plate groove 115 and temporarily deformed. When the fixing plate 150 abuts against the bottom of the fixing plate groove 115, the elastic buckles 152 recover their deformation and are clamped and fixed with the clamping holes 116 of the plastic body 110.
[0076] Please refer to Fig.13 , Fig.16 and Fig.17 A fixing column 117 is provided at the bottom 140, and a clamping hole 116 is provided on the fixing plate groove 115, a notch 151 is provided at the fixing plate 150, elastic buckles 152 are provided on both sides of the notch 151, and a fixing hole 153 is provided below the notch 151, and the elastic buckle 152 is clamped and fixed with the clamping hole 116.
[0077] In a specific implementation, the clamping holes 116 are arranged on both sides of the fixing plate groove 115 of the plastic body 110, and the clamping holes 116 are arranged symmetrically. The fixing plate 150 is bent in an L shape, and a notch 151 is arranged in the middle of one surface of the fixing plate 150. Elastic buckles 152 are arranged on both sides of the notch 151, and are arranged symmetrically. A fixing hole 153 is arranged on the other surface of the L-shaped bend and is located below the notch 151. During the assembly process, the fixing sheet 150 is pushed into the fixing sheet groove 115 along the assembly direction, and the fixing column 117 set at the bottom 140 of the plastic body 110 passes through the fixing hole 153 on the fixing sheet 150. The elastic buckles 152 on both sides of the fixing sheet 150 are squeezed by the inner wall of the fixing sheet groove 115 and temporarily deformed. When the notch 151 of the fixing sheet 150 abuts against the plastic body, the elastic buckles 152 of the fixing sheet 150 also reach the position of the clamping hole 116 of the plastic body. The elastic buckles 152 restore their deformation and engage with the clamping hole 116 to prevent the fixing sheet 150 from detaching from the plastic body in the opposite direction of the assembly direction.
