Description

[0001] This application is a divisional application of the following application, the original application date: January 20, 2021, the original application number: 2021100767776, the original application name: a connector and a connector assembly using the same. TECHNICAL FIELD

[0002] The application relates to the technical field of communication equipment, in particular to a connector and a connector assembly using the same. BACKGROUND

[0003] With the upgrading of communication speed, the system puts forward more stringent requirements on the high-speed electrical performance indicators of the connector, and the most critical electrical performance indicators are crosstalk, loss and reflection.

[0004] Therefore, the Chinese invention patent application with the application publication number CN109473805A designs a connector and a backboard interconnection system, wherein the connector includes a connector housing, and at least two rows of terminals are fixedly arranged on the connector housing. Each terminal row includes ground terminals and signal differential pairs arranged alternately. The signal differential pair includes two signal terminals. In order to improve the electrical performance indicators of the connector, the return path of the ground terminal is increased, and a shielding member is arranged on the connector housing. The shielding member is actually a shielding net, and the shielding net has good conductivity. The shielding net has ground terminal perforations (i.e. the connection holes of the patent application) and signal terminal perforations (i.e. the isolation holes of the patent application). The signal terminal is passed through the signal terminal perforation and does not contact the hole wall of the signal terminal perforation; the ground terminal is passed through the ground terminal perforation and contacts the hole wall of the ground terminal perforation. The shielding net electrically connects the ground terminals together, increases the ground path of the ground terminal, disperses the signal energy of the crosstalk, reduces the mutual inductance, and thus reduces the crosstalk between the signal terminals.

[0005] In the prior art, a groove is formed in the connector housing, and the shielding net is fitted into the groove. At the same time, the shielding net is fitted on the outside of the ground terminal. In addition, in order to further ensure the good fitting of the shielding net and the connector housing, a positioning protrusion is arranged on the connector housing. The positioning protrusion is an insulator, and the signal terminal perforation is fitted on the outside of the positioning protrusion.

[0006] The current problem of the connector is that the shielding net has many constraints during installation, and the overall size of the shielding net and the position size and inner diameter size of each hole are required to be high. If there is a slight deviation, the shielding net cannot be smoothly fixed to the connector housing. Moreover, since the shielding net needs to be clamped into the connector housing as a whole, and the ground terminal needs to be clamped inside, if the size deviates, the shielding net will expand at some positions, and even the shielding net will be damaged. SUMMARY

[0048] The beneficial effects are that the transverse shielding body is inserted into the transverse shielding body insertion slot.

[0101] The application will be further described in detail below in combination with the embodiments.

[0102] Specific embodiment 1 of the connector assembly provided by the application:

[0103] As shown in Figure 1 The connector assembly includes a female connector 100 and a male connector 200 that are inserted into each other, and here, whether the female connector 100 or the male connector 200, the end used for insertion is the front end.

[0104] The female connector 100 comprises a female housing 101 and a plurality of terminal modules 102 arranged on the female housing 101, wherein the terminal module 102 has a mounting end 103 and a mating end 104, the mounting end 103 is used to be fixedly mounted on the printed board, and the mating end 104 is used to be plugged with the male connector 200. The terminal module 102 is a square plate body as a whole, and the terminal modules 102 are arranged in sequence along the thickness direction of the terminal module 102.

[0105] The structure of the terminal module 102 is shown in Figures 2 to 10 The terminal module 102 comprises a support frame 1021, a terminal component 1022 and a shielding plate 1023 arranged in sequence along the thickness direction of the terminal module 102, wherein the support frame 1021 and the terminal component 1022 are injection molded together during assembly to form a primary injection molded part. In fact, the support frame 1021 can also not exist as a separate component, but can be formed by pouring insulating material outside the terminal component 1022.

[0106] The terminal component 1022 comprises female signal differential pairs and female ground terminals 10222 arranged in sequence and alternately, and each female signal differential pair comprises two female signal terminals 10221. The female signal terminals 10221 and the female ground terminals 10222 are arranged at intervals. During processing, the terminal component 1022 is formed by integral stamping, and residual material is used to connect adjacent terminals (including the female signal terminals 10221 and the female ground terminals 10222). After injection molding, the residual material is removed. The female signal terminals 10221 and the female ground terminals 10222 are both bent terminals, so that the female connector 100 forms a bent female.

[0107] The structure of the female signal terminal 10221 is shown in Figure 6 The female signal terminal 10221 has a signal spring piece 102211 at the mating end 104 of the terminal module 102, the signal spring piece 102211 itself has a certain bending and can elastically swing. During use, the signal pin insertion end 2021 is inserted into one side of the signal spring piece 102211 and presses the signal spring piece 102211, so that the signal spring piece 102211 and the signal pin insertion end 2021 can be in good contact, and signal conduction is realized. The female signal terminal 10221 has a mounting terminal at the mounting end 103 of the terminal module 102, which is a fish eye. In other embodiments, the mounting terminal can be a needle-shaped or column-shaped terminal for welding with the printed board.

[0108] The structure of the female ground terminal 10222 is shown in Figure 4 and Figure 15As shown, the female grounding terminal 10222 at the mating end 104 of the terminal module 102 has a grounding spring 102221, which is bent to be flexible. In use, the grounding pin insertion end 2031 is inserted into the channel formed by the grounding spring 102221 and the convex 10232, and is clamped by the grounding spring 102221 and the convex 10232 to realize grounding conduction and form shielding for signals. Figure 4 As shown, the female grounding terminal 10222 here is divided into two types, one is the middle grounding terminal 10222a, and the other is the side grounding terminal 10222b. The front end of the side grounding terminal 10222b is not provided with a grounding spring 102221. In actual use, the side grounding terminal 10222b can be provided on one side only, or on both sides, or can not be provided. The structure of the signal spring 102211 and the grounding spring 102221 is as shown in Figure 5 As shown, the signal spring 102211 includes a signal spring extension 1022111 extending forward, and a signal spring turning portion 1022112 and a signal spring inclined portion 1022113 at the front end. The signal spring inclined portion 1022113 extends obliquely. The grounding spring 102221 includes a grounding spring extension 1022211 extending forward, and a grounding spring turning portion 1022212 and a grounding spring inclined portion 1022213 at the front end. The grounding spring inclined portion 1022213 extends obliquely.

[0109] As shown, Figure 4 It can be seen that the grounding spring 102221 has a bifurcated structure. The female grounding terminal 10222 at the mounting end 103 of the terminal module 102 has a mounting terminal, which is a fish eye here.

[0110] The structure of the shielding plate 1023 is as shown in Figure 2 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 As shown, the shielding plate 1023 includes a main body portion 10231, which is a complete plate body. The front end (when in use, the end facing the male connector 200) of the main body portion 10231 has a convex 10232. The number of the convex 10232 is consistent with the number of the grounding spring 102221 in the same terminal module 102 and corresponds one by one in the thickness direction of the terminal module 102. The convex 10232 protrudes from the main body portion 10231 in the direction facing the grounding spring 102221, and is used to cooperate with the grounding spring 102221 to form a channel for the insertion of the grounding pin insertion end 2031. As shown in Figure 8As shown in the enlarged view of FIG. 10B, the front end of the convex bump 10232 is a guide slope, which is an inclined plane 10236 extending from front to back and towards the direction where the grounding spring 102221 is located. The inclination angle of the inclined plane 10236 is preferably 45°, and in other embodiments, the inclination angle can be changed according to actual conditions.

[0111] The reason for setting the inclined plane 10236 is that in the prior art, the front end of the convex bump 10232 is planar, and the reason why the grounding pin insertion end 2031 can enter the channel between the convex bump 10232 and the grounding spring 102221 is that the front end of the grounding spring 102221 is guided by the inclined surface. However, since the grounding spring 102221 is a sheet structure with a small width, the overall strength is low, and after the grounding pin insertion end 2031 presses the grounding spring 102221 for a long time, the grounding spring 102221 will be skewed, causing the grounding spring 102221 to fail to cooperate with the convex bump 10232 to clamp the grounding pin insertion end 2031, and the grounding shielding effect is poor. In this embodiment, the front end of the convex bump 10232 is designed as an inclined plane 10236, which guides the grounding pin insertion end 2031 into the channel by cooperating with the grounding pin insertion end 2031. The convex bump 10232 is located on the shielding plate 1023, which has a large overall width and is not easily deformed by the force.

[0112] As shown in the enlarged view of FIG. 10B, the front end of the convex bump 10232 is a guide slope, which is an inclined plane 10236 extending from front to back and towards the direction where the grounding spring 102221 is located. The inclination angle of the inclined plane 10236 is preferably 45°, and in other embodiments, the inclination angle can be changed according to actual conditions. Figure 8 As shown in the enlarged view of FIG. 10B, the front end of the convex bump 10232 is a guide slope, which is an inclined plane 10236 extending from front to back and towards the direction where the grounding spring 102221 is located. The inclination angle of the inclined plane 10236 is preferably 45°, and in other embodiments, the inclination angle can be changed according to actual conditions.

[0113] As shown in the enlarged view of FIG. 10B, the front end of the convex bump 10232 is a guide slope, which is an inclined plane 10236 extending from front to back and towards the direction where the grounding spring 102221 is located. The inclination angle of the inclined plane 10236 is preferably 45°, and in other embodiments, the inclination angle can be changed according to actual conditions. Figure 9 and Figure 10 As shown in the enlarged view of FIG. 10B, the front end of the convex bump 10232 is a guide slope, which is an inclined plane 10236 extending from front to back and towards the direction where the grounding spring 102221 is located. The inclination angle of the inclined plane 10236 is preferably 45°, and in other embodiments, the inclination angle can be changed according to actual conditions. Figure 14As shown in the figure, when the shielding plate 1023 is in conductive communication with the shielding net 107 by contacting, the elastic deformation of the second elastic arm 102341 ensures the close contact of the two, improves the reliability of the contact, and enhances the shielding effect. Moreover, in the embodiment, the second elastic arm 102341 is located at the front end of the shielding plate 1023, and the stress borne by the second elastic arm 102341 is transmitted in the front-back direction. Since the thickness of the shielding plate 1023 in the front-back direction is much larger than the thickness direction, the bearing capacity of the shielding plate 1023 in the front-back direction is greater than that in the thickness direction, and the shielding plate 1023 is not easy to deform in the front-back direction after being stressed. In actual use, a second elastic arm 102341 with larger size and greater elasticity can be selected to make the contact between the shielding plate 1023 and the shielding net 107 more reliable.

[0114] In the embodiment, in order to fix the shielding plate 1023 on the terminal component 1022 and the support frame 1021, and ensure that the female grounding terminal 10222 in the terminal component 1022 is in reliable contact with the shielding plate 1023, realize the common ground of each female grounding terminal 10222 in the same terminal module 102, and realize the common ground of each female grounding terminal 10222 in the female connector 100 through the shielding net 107, the grounding shielding effect is improved. As shown in the figure, Figure 2 and Figure 7 , Figure 9 As shown in the figure, a through rivet hole 10235 is formed on the female grounding terminal 10222, and a rivet hole is also formed on the support frame 1021 and the terminal component 1022. During assembly, a rivet 1024 is used to pass through the support frame 1021, the female grounding terminal 10222 and the shielding plate 1023 at the same time, so as to fix the three together. The rivet 1024 here is an insulator.

[0115] In order to ensure that the shielding plate 1023 can be in good contact with the female grounding terminal 10222, and at the same time there is a certain gap between the shielding plate 1023 and the female signal terminal 10221, so as to prevent the female signal terminal 10221 from being grounded, as shown in the figure, Figure 2 , Figure 7 , Figure 9 As shown in the figure, the side of the main body part 10231 of the shielding plate 1023 facing the terminal component 1022 has a protruding part 10233, and the protruding part 10233 protrudes from the main body part 10231. Among them, the protruding part 10233 corresponds to the female grounding terminal 10222 and extends along the direction of the female grounding terminal 10222. As shown in the figure, Figure 2 and Figure 3 As shown in the figure, a first elastic arm 102222 is arranged on the female grounding terminal 10222, and the first elastic arm 102222 is arranged protruding towards the protruding part 10233. The first elastic arm 102222 is in close contact with the protruding part 10233 through the elastic deformation of the first elastic arm 102222, so as to realize the conductive communication.

[0116] In this embodiment, the rivet 1024 is riveted on the support frame 1021 through the shielding plate 1023 and the female grounding terminal 10222 in turn, and the manufacturing process is simple.

The base of the female shell 101 is provided with multiple rows of sockets, which are arranged in the up-down direction and are arranged in a staggered manner. Figure 11 Each row of sockets includes female shell grounding pin sockets 1014 and male differential pair sockets arranged alternately, wherein the male differential pair sockets include two female shell signal pin sockets 1011. The female shell signal pin socket 1011 is provided for the signal pin 202 to be inserted, and the female shell grounding pin socket 1014 is provided for the grounding pin 203 to be inserted. During assembly, the signal spring sheet 102211 is located on one side of the female shell signal pin socket 1011 or can partially cover the female shell signal pin socket 1011; the grounding spring sheet 102221 is located on one side of the female shell grounding pin socket 1014 or can partially cover the female shell grounding pin socket 1014.

[0118] In order to isolate the two signal pins 202 of the same signal differential pair and prevent the two signal pins 202 from contacting, a signal pin isolation block 1013 is fixed on the female shell 101; in order to prevent the signal pin 202 from contacting the adjacent grounding pin 203, a signal grounding isolation block 1017 is fixed on the female shell 101. Whether it is the signal pin isolation block 1013 or the signal grounding isolation block 1017, it is arranged protruding in the interior of the female shell 101.

[0119] As shown in Figure 11 and Figure 12 , a differential pair isolation wall 1012 is also protrudingly arranged in the interior of the female shell 101, and the differential pair isolation wall 1012 is located on one side of the two female shell signal pin sockets 1011 corresponding to the same differential pair. The female shell 101 is also provided with a shielding plate support protrusion 1015 protruding therefrom, and the shielding plate support protrusion 1015 is arranged on the two sides of the differential pair isolation wall 1012 away from the female shell signal pin socket 1011. The shielding plate support protrusion 1015 and the differential pair isolation wall 1012 together form a clamping groove for the shielding plate 1023 to be clamped into, so as to clamp the shielding plate 1023 and prevent the shielding plate 1023 from being offset in the up-down direction. Figure 11

[0120] As shown in Figure 11 ​As shown, the side of the female end shell grounding pin socket 1014 is not provided with a shielding plate support protrusion 1015, which is a convex bump corresponding area 1016, which is used to correspond to the convex bump 10232.

[0121] The structure of the shielding net 107 is as shown in the figure Figure 13 As shown, the shielding net 107 is a plate-shaped structure, which is used to contact each shielding plate 1023 to achieve common grounding and better grounding shielding effect. The shielding net 107 has three types of through holes, namely signal pin through hole 1071, grounding pin through hole 1072 and shielding plate support protrusion through hole 1073. The signal pin through hole 1071 is adaptively sleeved outside the differential pair isolation wall 1012 and the signal ground isolation block 1017, and corresponds to the female end shell signal pin socket 1011 of the same differential pair. The grounding pin through hole 1072 corresponds to the female end shell grounding pin socket 1014. The shielding plate support protrusion through hole 1073 corresponds to the shielding plate support protrusion 1015, and can be adaptively sleeved outside the shielding plate support protrusion 1015. In the present application, the shielding net 107 is fixed on the female end shell 101 by clamping, which is more accurate in positioning and more firm in installation.

[0122] In the present application, when the female end connector 100 is installed, the shielding net 107 is first installed on the female end shell 101, and each terminal module 102 is sequentially inserted into the female end shell 101. The terminal module 102 and the female end shell 101 are assembled by the cooperation of the clamping block on the terminal module 102 and the clamping groove on the female end shell 101.

In this embodiment, since the convex bump 10232 is provided on the shielding plate 1023, and the front end of the convex bump 10232 has an inclined plane 10236, the convex bump 10232 can be arranged opposite to or as close as possible to the grounding pin through hole 1072 on the shielding net 107, so that the grounding pin 203 can be pressed on the inclined plane 10236 after being inserted into the grounding pin through hole 1072, avoiding the grounding pin 203 being pressed on the grounding elastic sheet 102221.
