Description

Technical Field

[0001] The utility model relates to a connection structure between an electric connector and a circuit board, belonging 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.

[0031] See also Figures 1 to 5 The connection structure of the electrical connector and the circuit board of the technical solution of the utility model includes a socket assembly 200 including a socket housing 210 and at least one pin 212 for connecting the circuit board 400, and the socket housing 210 and the pin 212 are integrally connected.

[0032] See also Figure 1 and Figure 5The electrical connector of the technical solution of the utility model includes a plug assembly 100 and a socket assembly 200, and the plug assembly 100 and the socket assembly 200 are connected. The plug assembly 100 is connected to the transmission cable 300, and 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, and 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, so as to realize signal transmission. Further, the conductive member 310 can be an elastic member.

[0033] 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.

[0034] In some embodiments, the socket housing 210 is provided with pins 212 for connecting with the circuit board 400. Specifically, the pins 212 are provided on the lower side of the socket housing 210, and the circuit board 400 is provided with corresponding pin holes 410. The pins 212 are inserted into the pin holes 410, and the socket assembly 200 is connected to the circuit board 400 by welding. Figure 1 and Figure 2 A plurality of pins 212 are provided on the socket housing 210 , and the plurality of pins 212 are symmetrically arranged at the lower front side and the lower rear side of the socket housing 210 .

[0035] In some embodiments, the pins 212 are covered with a rubber sleeve 213 for fixing, and the rubber sleeve 213 abuts against the inner wall of the pinhole 410, thereby improving the connection reliability between the socket housing 210 and the circuit board 400 and improving the welding accuracy of the two. Specifically, three pins 212 are respectively arranged on the front and rear sides of the socket housing 210, and the rubber sleeve 213 is covered on the pin 212 in the middle. It can be understood that the rubber sleeve 213 can be made of rubber material, and the socket housing 210 can be made of metal material.

[0036] It should be noted that in the conventional socket assembly 200 structure, the pins 212 made of plastic material and the socket housing 210 made of metal material are assembled into a whole. Since the molding precision of the plastic itself is low, the finished product error of the pins 212 and the socket housing 210 is large, which in turn has a great impact on the installation precision of the cushion 220. However, the socket housing 210 and the pins 212 of the utility model are made of metal material as an integrated structure, and the middle pin 212 is added, and the rubber sleeve 213 is put on the middle pin 212. By utilizing the characteristics that the molding precision of metal is greater than the molding precision of plastic, and eliminating the extra error caused by the assembly process of the socket housing 210 and the pins 212, the connection precision of the socket assembly 200 and the circuit board 400 is improved, which is conducive to ensuring the stability of the electrical connector during installation and welding.

[0037] Furthermore, the surface of the pin 212 is an anti-slip surface 214. When the rubber sleeve 213 contacts the anti-slip surface 214 of the middle pin 212, the anti-slip surface 214 helps prevent the rubber sleeve 213 from being separated from the pin 212. Figure 2 , discontinuous processing is performed on the middle pin 212, for example, pits are set on the surface of the pin 212 to destroy the connectivity of the surface of the pin 212. Specifically, the middle pin 212 is a square rod, and long strip pits are set at the four corners of the upper side of the middle pin 212, so that the surface of the middle pin 212 becomes a non-slip surface 214, and the rubber sleeve 213 is sleeved on the pit of the middle pin 212. It can be understood that anti-slip patterns can also be set on the surface of the pin 212 to increase the friction between the rubber sleeve 213 and the pin 212.

[0038] In some embodiments, see Figure 2 , Figure 3 and Figure 5 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.

[0039] 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 3The 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.

[0040] In some embodiments, see Figure 3 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.

[0041] 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 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.

[0042] For details, see Figure 3The 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 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 connecting 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.

[0043] 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.
