[0001] The present application relates to the technical field of connectors, and in particular to a line end connector and an electronic device. Background Art

[0002] With the booming development of the communications industry, various connection interfaces continue to pursue more reliable and more stable connection structures. At the same time, the transmission rate of signals is constantly rising. Taking the PCIE (peripheral component interconnect express, a high-speed serial computer expansion bus standard) interface as an example, the transmission rate of PCIE 3.0 is 8GT / s, the transmission rate of PCIE4.0 is 16GT / s, and the transmission rate of PCIE 5.0 is 32GT / s. The latest PCIE 6.0 has a transmission rate of 64GT / s. The higher the signal transmission rate, the greater the interference between signals. Under high-speed transmission signals, how to reduce the interference between signals is a difficulty for high-speed connectors. Grounding is a common method to eliminate interference signals. However, grounding different ground terminals separately will still cause great interference for high-speed transmission. Utility Model Content

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0031] At present, in order to meet the transmission rate requirements of PCIE 5 or even higher, the grounding terminals in the high-speed signal area of ​​the existing line-end connector are often connected in series. There are two rows of terminals in the high-speed signal area of ​​the line-end connector. One solution is to connect the grounding terminals in the two rows of terminals in series respectively, that is, one row of grounding terminals is connected in series, and the other row of grounding terminals is also connected in series, but the two rows of grounding terminals are not connected in series. Another solution is to partially connect the grounding terminals in the two rows of terminals in series, for example, one row of grounding terminals is connected in series in sections. However, the signal anti-interference ability is still low when the grounding PINs in the two rows of terminals are connected in series separately or partially. The present application provides a line-end connector to solve the above-mentioned technical problems, as described in detail in the following embodiments.

[0032] See also Figure 1 and Figure 2 , Figure 1 is a schematic diagram of a structure of a line end connector in a disassembled state provided by an embodiment of the present application, Figure 2 Schematic diagram of the structure of a line end connector assembly state provided by an embodiment of the present application. Figure 1 and Figure 2 As shown, the line end connector 10 includes an outer mold 11, a connector body 12, a signal line 13, a signal terminal 14, a ground connection component 15, a low-speed connector 16 and a PCB board 17.

[0033] The outer mold 11, the signal line 13, the signal terminal 14, and the ground connection assembly 15 form a high-speed connector. A slot 171 is provided in the middle of the PCB board 17, and first screw holes 172 are provided at both ends. The high-speed connector is arranged in the slot 171. A low-speed slot 121 is provided on the connector body 12 for arranging the low-speed connector 16, and second screw holes 122 are provided at both ends of the connector body 12. The first screw hole 172 is aligned with the second screw hole 122, and the connector body 12 is fixed to the PCB board 17 by screws 200 and nuts 300.

[0034] The signal line 13 is used to transmit the signal of the line end connector 10, specifically, to transmit the signal of the high-speed connector. In order to meet the requirements of higher transmission rate, two rows of signal lines 13 are arranged in this embodiment. A wire hole 111 is arranged on the outer mold 11 for fixing the signal line 13. That is, the signal line 13 passes through the wire hole 111 to be fixed on the outer mold 11. The signal terminal 14 is electrically connected to the signal line 13. Similarly, the signal terminal 14 is also arranged in two rows, and each row of signal terminals 14 is electrically connected to a corresponding row of signal lines 13. The signal terminal 14 includes at least two grounding terminals 141, and the grounding terminal 141 is used to ground the high-speed connector. In this embodiment, the signal terminal 14 includes a plurality of grounding terminals 141, and the plurality of grounding terminals 141 are also arranged in two rows. The connector body 12 is used to fix the signal terminal 14. The grounding connection assembly 15 is electrically connected to the at least two grounding terminals 141 respectively to connect the grounding terminals 141 in series. Specifically, the ground connection assembly 15 is electrically connected to the multiple ground terminals 141 arranged in two rows, and the multiple ground terminals 141 arranged in two rows are connected in series.

[0035] It should be understood that in other embodiments, if there are more than two rows of ground terminals 141, the ground connection assembly 15 is electrically connected to the more than two rows of ground terminals 141, and the multiple ground terminals 141 arranged in the more than two rows are connected in series. In other words, the ground connection assembly 15 of this embodiment connects all the ground terminals 141 in series. All the ground terminals 141 are grounded in series, thereby improving the anti-interference ability of the signal.

[0036] See also Figure 3 , Figure 3 1 is a schematic diagram of the structure of the ground connection assembly 15 in an exploded state. Figure 3 As shown, the ground connection assembly 15 includes a ground connection member 151 and a ground support member 152, wherein the ground connection member 151 is fixed on the ground support member 152, and the ground connection member 151 is made of conductive material, for example, a metal conductor such as stainless steel or copper can be used. The ground connection member 151 is in elastic contact with the ground terminal 141. The ground connection member 151 is in elastic contact with the ground terminal 141, so that the contact between the ground connection member 151 and the ground terminal 141 is more stable and reliable, and the service life is improved. In addition, since the ground connection member 151 is made of conductive material, the contacting ground terminals 141 can be connected in series to improve the anti-interference effect.

[0037] The grounding connector 151 includes a connection body 1511 and a connection terminal 1512 extending from the edge of the connection body 1511. As mentioned above, for high-speed transmission, the line end connector 10 is provided with two rows of grounding terminals 141, so two rows of connection terminals 1512 are also provided, which are respectively extended from the two side edges of the connection body 1511. The connection body 1511 is fixed to the grounding support 152, which can be fixed by injection molding or clamping. The connection terminal 1512 is in elastic contact with the grounding terminal 141.

[0038] Specifically, see Figure 4 , Figure 4 yes Figure 3 The structure of the grounding connector 151 in the A region is shown in FIG. Figure 4 As shown, the connecting terminal 1512 includes a terminal body 1513 and an elastic contact 1514 . One end of the terminal body 1513 is connected to the connecting body 1511 , and the elastic contact 1514 is arranged at the other end of the terminal body 1513 .

[0039] Among them, the elastic contact 1514 includes a contact body 1515 and a contact connecting portion 1516, one end of the contact connecting portion 1516 is connected to the terminal body 1513, and forms an acute angle with the terminal body 1513, and the space of the acute angle can provide elastic displacement space when the grounding connector 151 and the grounding terminal 141 are in elastic contact. The other end of the contact connecting portion 1516 is connected to the contact body 1515, and the contact body 1515 is an arc structure, and the grounding terminal 141 elastically abuts on the arc surface of the arc structure of the contact body 1515. When the contact body 1515 and the grounding terminal 141 are in elastic contact, the contact body 1515 is subjected to the elastic extrusion force and moves in the direction of the terminal body 1513. The elastic displacement formed by the elastic extrusion is 0.1 mm to 0.5 mm. The grounding connector 151 is made into an elastic structure, and the contact with the grounding terminal 141 is more stable and reliable, which improves the service life.

Figure 5 As shown, the width of the first support portion 1521 is greater than the width of the second support portion 1522 , so that the outer side surface of the first support portion 1521 is outside the outer side surface of the second support portion 1522 , so that the signal terminal 14 is arranged outside the connection terminal 1512 of the ground connection member 151 .

[0042] The signal terminal 14 includes a first section 142 and a second section 143. The first section 142 is accommodated in the first groove 1523 of the first support portion 1521, and the second section 143 is bent in a direction close to the second groove 1524, that is, in a direction close to the connecting terminal 1512, so as to facilitate the contact between the grounding terminal 141 in the signal terminal 14 and the connecting terminal 1512.
