[0002] With the booming development of the communications industry, various connection interfaces continue to pursue more reliable and more stable connection structures.

DETAILED DESCRIPTION

[0034] 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.

[0035] At present, in order to meet the transmission rate requirements of PCI E 5 or even higher, the ground terminals in the high-speed signal area of ​​the existing line-end connector are often connected in series. The line-end connector has two rows of terminals in the high-speed signal area, and the ground terminals are usually connected in series through a ground connector. However, the connecting terminal of the ground connector is usually designed to be a wavy structure, with the trough welded to the ground terminal, and the crest is parallel to the ground terminal structure of the signal terminal. The connecting terminal of this structure is not easy to assemble, and the contact with the ground terminal is unstable. The present application provides a line-end connector to solve the above-mentioned technical problems, as described in detail in the following embodiments.

[0036] 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 1 is a schematic diagram of a 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 connector 15, a low-speed connector 16 and a PCB board 17.

[0037] The outer mold 11, the signal line 13, the signal terminal 14, and the ground connector 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.

[0038] 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 rates, 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. Please refer to Figure 3 and Figure 4 , Figure 3 yes Figure 1 The schematic diagram of the structure of the grounding connector is shown in FIG. Figure 4 yes Figure 1 The grounding connector 15 is shown as a schematic diagram of a structure in which the grounding connector is connected to the outer mold and the grounding terminal respectively. The grounding connector 15 is made of conductive material, for example, a metal conductor such as stainless steel or copper can be used. The grounding connector 15 includes a connecting terminal 151, which is in a planar shape. The connecting terminal 151 is respectively attached to at least two grounding terminals 141 to form an electrical connection, thereby connecting the grounding terminals 141 in series. Specifically, the grounding connector 15 is also provided with two rows of connecting terminals 151, which are respectively attached to and electrically connected to the multiple grounding terminals 141 arranged in two rows, and the multiple grounding terminals 141 arranged in two rows are connected in series. It should be understood that in other embodiments, if there are more than two rows of grounding terminals 141, the connecting terminals 151 of the grounding connector 15 are also arranged in more than two rows, and the connecting terminals 151 in more than two rows are respectively attached to and electrically connected to the multiple grounding terminals 141 arranged in more than two rows, and the multiple grounding terminals 141 arranged in more than two rows are connected in series. That is to say, the grounding connector 15 of the conductive material of this embodiment connects all the grounding terminals 141 in series. The ground terminal 141 is connected to the ground in series, and the connection terminal 151 of the ground connector 15 is in contact with the ground terminal 141 in a fitted manner, thereby improving the anti-interference capability of the signal.

[0039] Please also read Figure 5 , Figure 5 yes Figure 4Schematic diagram of the enlarged structure of the area A in the middle. The connector body 12 is used to position and fix the grounding connector 15. Specifically, at least one first positioning column 123 is provided on the outer surface of the connector body 12, and the grounding connector 15 is provided with a first fixing hole 152 corresponding to the first positioning column 123, and the first positioning column 123 is inserted into the first fixing hole 152. Among them, the position of the first positioning column 123 is set so that when the first positioning column 123 is inserted into the first fixing hole 152, the connecting terminal 151 can be fitted with the grounding terminal 141 to form an electrical connection. In other words, the position of the first positioning column 123 needs to be determined according to the matching relationship between the grounding terminal 141 and the connecting terminal 151, and the first fixing hole 152 of the grounding connector 15 is matched with the first positioning column 123 of the connector body 12, so that the positioning of the grounding connector 15 is simple and reliable.

[0040] The first positioning column 123 is tightly matched with the first fixing hole 152 to fix the grounding connector 15 on the connector body 12. Specifically, the connector body 12 is made of plastic material, which can be softened by heating and can be squeezed and deformed in the softened state. Before the first positioning column 123 and the first fixing hole 152 are installed and matched, the outer diameter of the first positioning column 123 of the connector body 12 is smaller than the inner diameter of the first fixing hole 152, so that there is a gap between the first positioning column 123 and the first fixing hole 152 after the first positioning column 123 is inserted into the first fixing hole 152. However, the volume of the first positioning column 123 is equivalent to that of the first fixing hole 152, and the volume of the first positioning column 123 can even be slightly larger than the volume of the first fixing hole 152. After the first positioning column 123 and the first fixing hole 152 are installed, that is, after the first positioning column 123 is inserted into the first fixing hole 152 to realize the positioning of the grounding connector 15, the first positioning column 123 is acted on by hot melting and pressure, so that the first positioning column 123 after hot melting and pressure is deformed to fill the gap between the first positioning column 123 and the first fixing hole 152, so that a tight fit is formed between the first positioning column 123 and the first fixing hole 152, thereby realizing the fixation between the grounding connector 15 and the connector body 12.

The connecting terminal 151 is fitted with the side of the grounding terminal 141 that faces the opening of the accommodating cavity 181, and is connected by welding at the position where the connecting terminal 151 and the grounding terminal 141 are fitted. That is, in this embodiment, the grounding terminal 141 and the connecting terminal 151 are fully contacted by fitting the planar sides of the grounding terminal 141 and the connecting terminal 151, and the two are further stably connected by welding.

[0042] The outer side surface of the connector body 12 protrudes outward relative to the grounding terminal 141. The grounding connector 15 also includes a main body 153 and a transition portion 154. The main body 153 is attached to the outer side surface of the connector body 12, and the first fixing hole 152 is provided on the main body 153. One end of the transition portion 154 is connected to the main body 153, and the other end is bent toward the direction of the grounding terminal 141, and the connection terminal 151 is connected to the other end of the transition portion 154. Thus, a smooth connection between the main body 153 and the connection terminal 151 can be achieved through the transition portion 154.

[0043] Optionally, a plurality of second fixing holes 124 are provided inside the connector body 12, and the other end of the signal terminal 14 is inserted into the second fixing hole 124 for fixing. That is, one end of the signal terminal 14 is provided in the accommodating cavity 181 of the grounding support member 18, and is respectively electrically connected to the signal line 13 and the connecting terminal 151 in the accommodating cavity 181, and the other end of the signal terminal 14 is inserted into the second fixing hole 124 and fixed on the connector body 12.

In other words, the grounding connector 15 is wrapped by the outer mold 11 and isolated from the outside, so that the grounding connector 15 will not be oxidized, and is more reliable and durable.
