[0001] The utility model relates to an electric connector and belongs to the technical field of electric signal transmission. Background Art

[0002] As the signal transmission rate and power density continue to increase, the requirements for the electrical characteristics of high-speed signals are also increasing. The use of traditional PCB as a signal transmission carrier not only leads to problems of poor signal integrity such as attenuation, crosstalk, and distortion in high-speed signal transmission, but also leads to practical problems such as insufficient internal space for the signal transmission carrier. Replacing the traditional PCB board signal transmission method with an electrical connector can largely solve the above problems. However, the size of the electrical connector is small, and its internal structure is also complex. The installation accuracy and connection reliability between its structures will directly affect the electrical performance of the electrical connector. If the electrical connector is not carefully designed and installed, its electrical performance will not only fail to meet the design expectations, but may even deteriorate sharply.

The plug partition 160 is connected to the socket partition 230 and the connecting part thereof is provided in the connecting groove, and the connecting groove is provided with a knife edge to allow the connection to be misaligned.

[0038] It is understandable that the connection groove can be provided on the socket connection plate 240 of the socket assembly 200, or can be provided in the plug connection plate of the plug assembly 100. Here, the socket connection plate 240 is provided with a second connection groove 243 as a connection groove as an example, the electrical connector includes a plug assembly 100 and a socket assembly 200, the plug assembly 100 includes a plug partition 160, the socket assembly 200 includes a socket partition 230 and a socket connection plate 240, the socket connection plate 240 is provided with a second connection groove 243, wherein the plug partition 160 is connected to the socket partition 230 and the connection portion thereof is provided in the second connection groove 243, and the second connection groove 243 is provided with a knife edge 244 that allows the connection portion to be misaligned.

[0039] See also Figure 1 and Figure 2 The electrical connector of the utility model technical solution includes a plug assembly 100 and a socket assembly 200, and the plug assembly 100 and the socket assembly 200 are connected. Figure 8 The plug assembly 100 is connected to the transmission cable 300, the transmission cable 300 is connected to one end of the conductive member 310, the socket assembly 200 is used to connect the circuit board 400, the circuit board 400 is connected to the cushion 220, the plug assembly 100 is inserted into the socket assembly 200, and the other end of the conductive member 310 is connected to the cushion 220, thereby realizing signal transmission. Further, the conductive member 310 can be an elastic member.

[0040] Specifically, the plug assembly 100 is provided with a plug housing 110, a plug connection plate and a plurality of plug partitions 160, the plug connection plate and the plug partition 160 are arranged in the cavity of the plug housing 110, and the plurality of plug partitions 160 are parallel to each other and connected to the plug connection plate. The socket assembly 200 includes a socket housing 210, a socket connection plate 240 and a plurality of socket partitions 230, the socket connection plate 240 and the socket partition 230 are arranged in the cavity of the socket housing 210, and the plurality of socket partitions 230 are parallel to each other and connected to the socket connection plate 240. When the plug housing 110 is inserted into the socket housing 210, the plug partition 160 can abut against the socket partition 230, thereby forming an independent space for accommodating the conductive member 310 and having a shielding effect. It should be noted that the plug housing 110, the socket connection plate 240 and / or the socket partition 230 can be made of metal.

[0041] In some embodiments, the socket connecting plate 240 is provided with a second connecting groove 243, and the connection between the plug partition 160 and the socket partition 230 is located in the second connecting groove 243. Figure 2 and Figure 4 The plug partition 160 is provided with a plurality of plug partitions 160, the plurality of plug partitions 160 are parallel to each other, the number of the plug partitions 160 is the same as the number of the socket partitions 230, and the lower end of the plug partition 160 is connected to the lower end of the socket partition 230, thereby forming an independent space for placing the conductive member 310 and having a shielding effect. Furthermore, the plug partitions 160 abut against the plug partitions 160, which can reduce the probability of gaps appearing at the connection.

[0042] In some embodiments, the socket connecting plate 240 is inserted into the first connecting groove 234 of the socket partition 230, the upper end of the socket partition 230 is located in the middle of the socket connecting plate 240, and the socket connecting plate 240 is provided with a second connecting groove 243, and the opening of the second connecting groove 243 faces upward. When the plug assembly 100 is inserted into the socket assembly 200, the lower side of the plug partition 160 is inserted into the second connecting groove 243, thereby playing a positioning and guiding role, thereby improving the connection accuracy of the electrical connector.

[0043] In some embodiments, the second connection groove 243 is provided with a cutting edge 244 that allows the connection to be misaligned. Figure 2 and Figure 3The plug partition 160 is crimped and matched with the socket partition 230, that is, when the plug partition 160 applies downward pressure to the socket partition 230, the lower end of the plug partition 160 is offset in one direction, and the upper end of the socket partition 230 is offset in the opposite direction. The blade 244 is provided with two offset recesses 245, and the recessed direction of the offset recess 245 on the upper side matches the offset direction of the socket partition 230 when crimped, and the recessed direction of the offset recess 245 on the lower side matches the offset direction of the plug partition 160 when crimped, so that the shape of the blade 244 matches the active direction when the connection between the two partitions is misaligned, so as to achieve close fit between the plug partition 160 and the socket partition 230, reduce or even eliminate the gap between the partition pieces, and improve the electrical performance of the electrical connector.

[0044] Further, the plug partition 160 is provided with a first inclined surface 161, and the socket partition 230 is provided with a second inclined surface 235 which can be pressed with the first inclined surface 161. When the plug partition 160 and the socket partition 230 are pressed and matched, the first inclined surface 161 and the second inclined surface 235 are relatively misaligned, for example, see Figure 3 The first inclined surface 161 is arranged at the lower end of the plug partition 160 and extends from top to bottom toward the front side. The second inclined surface 235 is arranged at the upper end of the socket partition 230 and extends from top to bottom toward the front side. When the plug partition 160 applies downward pressure to the socket partition 230, the first inclined surface 161 and the second inclined surface 235 are relatively displaced. The lower end of the plug partition 160 is offset forward and downward, and the lower end of the plug partition 160 enters the offset recess 245 on the lower side. The lower end of the socket partition 230 is offset backward and upward, and the lower end of the socket partition 230 enters the offset recess 245 on the upper side. Correspondingly, the offset recess 245 on the lower side of the blade 244 extends from top to bottom toward the front side, and the offset recess 245 on the upper side of the blade 244 extends from bottom to top toward the rear side.

[0045] In some embodiments, see Figure 5 , Figure 6 and Figure 8 A plurality of positioning grooves 211 are provided on the outer edge of the lower end of the socket shell 210, and the plurality of positioning grooves 211 are symmetrically arranged on the left and right sides of the socket shell 210. The two sides of the socket partition 230 are respectively embedded in the two symmetrical positioning grooves 211 on the left and right sides. Therefore, after the socket partition 230 is placed in the positioning groove 211 accordingly, the socket partition 230 and the socket shell 210 are welded, and the installation position of the socket partition 230 in the socket shell 210 can be positioned by the groove structure, thereby improving the installation accuracy of the partition, and the socket shell 210 can be formed by a mold stamping method to achieve higher manufacturing accuracy.

[0046] In some embodiments, at least one positioning protrusion 231 is disposed on the side of the socket partition 230, and the positioning protrusion 231 is embedded in the positioning groove 211. Figure 5 The socket partition 230 includes a partition body 232 and at least one positioning protrusion 231. The positioning protrusion 231 is arranged on the lower side of the partition body 232 and protrudes from the left and / or right side of the partition body 232. Here, two positioning protrusions 231 are provided as an example. When the upper side of the partition body 232 enters the cavity of the socket partition 230, the positioning protrusion 231 enters the positioning groove 211 from the lower opening of the positioning groove 211, so that multiple socket partitions 230 are connected to each other in the socket housing 210, thereby playing a mutual support role, which can improve the structural strength of the entire socket assembly 200. It should be noted that the thickness of the positioning protrusion 231 can be set to be slightly smaller than the width of the positioning groove 211, so that the positioning protrusion 231 can be embedded in the positioning groove 211, and the positioning protrusion 231 can move very little in the front and back of the positioning groove 211. Further, the left and right sides of the partition body 232 are in contact with the inner wall of the socket housing 210.

[0047] In some embodiments, see Figure 5 The socket partition 230 includes a partition body 232 and two positioning protrusions 231. The two positioning protrusions 231 are arranged on both sides of the lower end of the partition body 232 and protrude below the partition body 232, so that a slot 233 is arranged between the two positioning protrusions 231. A plurality of socket partitions 230 are provided. The plurality of socket partitions 230 are parallel to each other and arranged in an array, thereby forming a space for placing the cushion 220. Further, the left and right sides of the cushion 220 contact the inner sides of the two positioning protrusions 231, so that the cushion 220 can be positioned and fixed.

[0048] In some embodiments, the socket assembly 200 further includes a socket connecting plate 240, and the socket connecting plate 240 is connected to at least one socket partition 230. Figure 3 and Figure 4 A plurality of socket partitions 230 are arranged on the socket assembly 200, and a first connecting groove 234 is arranged in the middle of the lower end of each socket partition 230, and the opening of the first connecting groove 234 faces downward. When the socket connecting plate 240 is connected to all the socket partitions 230, the socket connecting plate 240 enters the first connecting groove 234, and the plurality of socket partitions 230 are parallel to each other, and the socket connecting plate 240 is perpendicular to the plurality of socket partitions 230, so that criss-crossing partitions are arranged in the socket housing 210 to form a plurality of independent shielding spaces for accommodating the conductive parts 310.

[0049] For details, see Figure 5The lower side of the socket partition 230 is provided with a slot 233 and a positioning protrusion 231, the slot 233 is provided between at least two positioning protrusions 231, the first connection slot 234 is provided in the middle of the bottom wall of the slot 233, and the opening of the first connection slot 234 faces downward. The socket connecting plate 240 is provided with a second connection slot 243, the opening of the second connection slot 243 faces upward, and the positions of the first connection slot 234 and the second connection slot 243 are adapted to each other, allowing the socket partition 230 to enter the second connection slot 243 while the socket connecting plate 240 enters the first connection slot 234. When the socket partition 230 is connected to the socket connecting plate 240, the bottom wall of the first connection slot 234 abuts against the bottom wall of the second connection slot 243, so that the bottom surface of the partition body 232 and the bottom surface of the connecting plate body are on the same plane, forming a partition cavity that can accommodate the cushion 220. When the cushion 220 is placed in the partition cavity, the front and rear sides of the cushion 220 are in contact with the inner side of the connection protrusion 242, and the left and right sides of the cushion 220 are in contact with the inner side of the positioning protrusion 231, thereby positioning the cushion 220. Furthermore, the depth of the first connection groove 234 is less than the depth of the second connection groove 243, so that when the socket partition 230 is inserted into the socket connection plate 240, the upper end of the socket partition 230 can be located in the second connection groove 243, so as to achieve connection with the plug partition 160 in the second connection groove 243.

[0050] In some embodiments, the socket connecting plate 240 is provided with a connecting protrusion 241 for positioning the cushion member 220. Figure 1 and Figure 4 The socket connecting plate 240 includes a connecting plate body and a connecting protrusion 241. The connecting protrusion 241 is arranged on the lower side of the connecting plate body. The connecting plate body is connected to the partition body. The connecting protrusion 241 protrudes from the bottom of the socket partition 230. The cushion 220 is provided with a corresponding connecting hole. The connecting protrusion 241 is inserted into the connecting hole to locate the position of the cushion 220.

[0051] Furthermore, the maximum width of the connection protrusion 241 is greater than the diameter of the connection hole, which can improve the connection stability between the gasket 220 and the socket connection plate 240, improve the installation accuracy of the gasket 220 on the socket assembly 200, and make it unnecessary to add a corresponding positioning fixture when welding the gasket 220. Specifically, the connection protrusion 241 is a flat plate with a quasi-circular structure. The connection protrusion 241 is parallel to the connection plate body, and the upper outer wall is connected to the bottom surface of the connection plate body. The diameter of the connection protrusion 241 is slightly larger than the diameter of the connection hole. When the connection protrusion 241 is inserted into the PCB board, the outer wall of the connection protrusion 241 abuts against the inner wall of the connection hole, and stress is generated between the socket connection plate 240 and the gasket 220, so that the gasket 220 is first fixed in the partition cavity and then welded, which can improve the installation accuracy.

[0052] Furthermore, the socket connecting plate 240 is provided with a connecting protrusion 242, which protrudes from the bottom of the socket connecting plate 240, thereby forming a partition cavity for placing the cushion 220 together with the positioning protrusion 231. Specifically, two connecting protrusions 242 are provided, and the two connecting protrusions 242 are provided at the front side and the rear side of the lower end of the socket connecting plate 240. The two connecting protrusions 242 extend in a direction away from the socket connecting plate 240, and the inner sides of the two connecting protrusions 242 are respectively in contact with the front side and the rear side of the cushion 220, which can improve the installation accuracy of the cushion 220.

[0053] It is understandable that the plug opening 111 of the plug housing 110 is also provided with a positioning auxiliary groove 114, the opening of the positioning auxiliary groove 114 faces downward, and the position of the positioning auxiliary groove 114 matches the position of the positioning groove 211, so that one positioning auxiliary groove 114 can communicate with one positioning groove 211, and one positioning protrusion 231 can pass through one positioning groove 211 and one positioning auxiliary groove 114 at the same time. When the plug assembly 100 is inserted into the socket assembly 200, the plug housing 110 enters the inner cavity of the socket housing 210, and the inner side of the positioning protrusion 231 in the positioning groove 211 enters the positioning auxiliary groove 114 matching its position (see Figure 7 ). Further, the front side, the rear side, the left side and / or the right side of the lower edge of the plug housing 110 are provided with positioning auxiliary grooves 114, and the positioning auxiliary grooves 114 allow the positioning protrusions 231 or the connecting protrusions 242 to be inserted.
