Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical connector technology, and in particular to a female socket and an electrical connector assembly. Background Technology
[0002] Currently, female sockets on the market typically have two rows of terminal groups, with each row using signal pins and ground pins arranged alternately. Between the two rows of terminal groups, a terminal pin (a terminal pin is a key metal component on an electrical connector (which can be a female socket or a male plug, and the female socket and male plug can be mated to form a connector group) is used as a GND pin (a ground pin is a grounding pin used to ground the circuit, and it conducts static electricity and interference signals into the ground, protecting the electrical connector and personnel, and preventing connector damage or electric shock accidents caused by leakage, static electricity accumulation, etc.) for isolation.
[0003] However, since the terminal pins in the middle of the two rows of terminal groups need to be assembled using a pin insertion process (a pin insertion process is an assembly process in which terminal pins are inserted into the first isolation hole of the female socket and then fixed by welding), this increases the complexity of the assembly process of the traditional female socket, thereby increasing the assembly cost and difficulty of the traditional female socket.
[0004] In addition, since the terminal pins in the middle of the two rows of terminal groups are used as grounding pins for isolation, there is an ungrounded area in the middle of the two rows of terminal groups of the traditional female socket. The signal pins must be placed in the middle area with grounding isolation in order to achieve the best isolation effect. Therefore, the traditional female socket has the defect of poor isolation effect. Utility Model Content

[0027] The second isolation piece is fixed inside the second isolation hole, and the second isolation piece has two second protrusions that protrude along the thickness direction of the plug body;
[0028] The two second protrusions are opposite to each other along the length of the plug body.
[0029] In some embodiments, each row of the pin group includes:
[0030] A plurality of connecting pins, wherein the plurality of connecting pins are arranged along the length direction of the plug body at a preset target spacing;
[0031] When the male plug is connected to the female socket, the connecting pins in the pin group can be inserted into the connection slots of the ground pin and signal pin in the terminal group of the female socket.
[0032] In some embodiments, when the male plug is connected to the female socket, the two second protrusions abut against the first protrusion on the first insulating piece of the female socket on the side of the two protrusions that are close to each other in the length direction of the plug body.

[0060] In one embodiment, please refer to Figures 1-4 The female socket 100 includes: a socket body 1, two rows of terminal blocks and a first insulating piece 3.
[0061] In another embodiment, the female socket 100 may also be provided with N rows of terminal groups, and the N rows of terminal groups are arranged along the width direction 1001 of the socket body 1, wherein N is a positive integer greater than 2.
[0062] In one embodiment, a first isolation hole 101 is provided at the middle position of the socket body 1.
[0063] It is understandable that the two rows of terminal groups are arranged on the socket body 1, and the two rows of terminal groups are symmetrical about the first isolation hole 101 in the width direction 1001 of the socket body 1.
[0064] In another embodiment, the socket body 1 has N-1 first isolation holes 101.
[0065] It should be noted that there is a first isolation hole 101 between two adjacent rows of terminal groups in the N-row terminal groups, and the two adjacent rows of terminal groups are symmetrical about one of the corresponding first isolation holes 101 in the N-1 first isolation holes 101.
[0066] In some embodiments, such as Figures 1-4 As shown, the first isolation plate 3 is fixed inside the first isolation hole 101, and the first isolation plate 3 has a first protrusion 301 protruding along the thickness direction 1002 of the socket body 1.
[0067] Specifically, the first isolation piece 3 can be used as the GND pin of the female terminal socket 100, and the first protrusion 301 and the first isolation piece 3 are integrally formed.
[0068] Generally speaking, GND pin is a grounding pin used to ground a circuit. GND pin can conduct static electricity and interference signals in the circuit to the ground, thus protecting electrical connectors and personnel safety and preventing connector damage or electric shock accidents caused by leakage, static electricity accumulation, etc.
[0069] It should be noted that, in combination Figure 7 and Figure 8 It is known that the conventional female socket 300 uses terminal pin 3001 as GND pin, and the connecting protrusion 4002 on the male isolation piece 4001 of the conventional male plug 400 is inserted into the terminal pin 3001 of the conventional female socket 300, so that the conventional female socket 300 and the conventional male plug 400 form an electronic connection, thereby forming a conventional electrical connector group 2000. Therefore, there is an ungrounded isolation area in the middle of the conventional female socket 300, which makes the isolation effect between the two rows of conventional terminal groups poor, resulting in poor anti-crosstalk effect of the conventional female socket 300, and also reduces the selectivity of the arrangement position of the conventional signal pin 3002 of the conventional female socket 300.
[0070] Specifically, terminal pin3001 is a terminal pin, which is a key metal component on an electrical connector used to achieve electrical connection. It can be understood as a needle-shaped or sheet-shaped metal body in an electrical connector that completes the conductive transmission of electrical signals.
[0071] To further explain, by Figures 1-8 It can be seen that the above-mentioned electrical connector can be a female socket 100 or a male plug 200, and the female socket 100 and the male plug 200 can be matched together to form an electrical connector group 1000.
[0072] When the first isolation plate 3 is fixed in the first isolation hole 101, the first protrusion 301 corresponds to the two rows of terminal groups, so that the two rows of terminal groups are separated by the first protrusion 301. The conventional female socket 300 uses a pin insertion process to assemble the terminal pin 3001 to achieve isolation between the two rows of conventional terminal groups. Compared with the conventional female socket 300, this female socket 100 has a simpler assembly process, so this female socket 100 has a lower assembly cost and assembly difficulty.
[0073] To further explain, the pin insertion process is an assembly process in which terminal pins are inserted into the first isolation hole of the female socket and then fixed by soldering.
[0074] In addition, each row of terminal blocks has a first dimension in the length direction 1003 of the socket body 1, and the first protrusion 301 has a second dimension in the length direction 1003 of the socket body 1.
[0075] Furthermore, the first dimension is no larger than the second dimension, which allows the first protrusion 301 to achieve complete isolation between the two rows of terminal groups located on both sides of the first protrusion 301. This ensures that there is no ungrounded area between the two rows of terminal groups located on both sides of the first protrusion 301, thereby enabling the female socket to effectively prevent crosstalk between the signal pins in the two rows of terminal groups. At the same time, it also allows for a greater selection of the arrangement positions of the signal pins in the two rows of terminal groups.
[0076] In some embodiments, according to Figures 1-4 It can be seen that the first isolation hole 101 extends through the socket body 1 on both opposite sides along its length direction 1003, and the shape and size of the first isolation hole 101 are adapted to the first isolation piece 3.
[0077] In some embodiments, refer to Figures 1-4 It can be seen that the socket body 1 has a first groove 102, a boss 103 and two rows of mounting holes 104.
[0078] Specifically, the boss 103 protrudes from the bottom surface of the first groove 102, and the two rows of mounting holes 104 are symmetrical about the boss 103 in the width direction 1001 of the socket body 1.
[0079] To further explain, each row of mounting holes 104 is composed of several mounting holes 104 arranged along the length direction 1003 of the socket body 1 at a preset target spacing.
[0080] It should be noted that each mounting hole 104 is formed between the outer wall of the boss 103 and the inner wall of the first groove 102, and the mounting hole 104 extends through the socket body 1 on opposite sides in its thickness direction 1002.
[0081] In some embodiments, please continue to refer to Figures 1-4 Each row of terminal blocks includes: ground pin 21 and signal pin 22.
[0082] The mounting holes 104 are fixed in the corresponding mounting hole group 104, and the grounding pin 21 and the signal pin 22 are arranged at intervals along the length direction 1003 of the socket body 1.
[0083] In addition, both the ground pin 21 and the signal pin 22 have a connection slot 201, and the opening direction of the connection slot 201 is the same as the opening direction of the first groove 102.
[0084] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6 The electrical connector assembly 1000 includes a male plug 200 and the aforementioned female socket 100.
[0085] In this embodiment of the application, the male plug 200 is connected to the female socket 100 to form an electrical connector assembly 1000.
[0086] In one embodiment, please continue to refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 The male plug 200 includes: a plug body 2001, two rows of pins, and a second insulating plate 2003.
[0087] The plug body 2001 has a second isolation hole 2002 at the middle position.
[0088] In addition, two rows of pin groups are arranged on the plug body 2001, and the two rows of pin groups are symmetrical about the second isolation hole 2002 in the width direction 1001 of the plug body 2001.
[0089] In addition, the second isolation plate 2003 is fixed inside the second isolation hole 2002, and the second isolation plate 2003 has two second protrusions 2004 protruding along the thickness direction 1002 of the plug body 2001.
[0090] Furthermore, the two second protrusions 2004 are opposite to each other along the length direction 1003 of the plug body 2001.
[0091] It should be noted that both second protrusions 2004 are integrally formed with the second isolation plate 2003.
[0092] In another embodiment, such as Figures 1-6 As shown, when the female socket 100 has N rows of terminal groups, the male plug has a corresponding N rows of pin groups, and the plug body 2001 has a corresponding N-1 second isolation holes 2002. There is also a second isolation hole 2002 between two adjacent rows of pin groups in the N rows of pin groups, and the two adjacent rows of pin groups are also symmetrical about a corresponding second isolation hole 2002 in the N-1 second isolation holes 2002.
[0093] In some embodiments, combined with Figures 1-6 It can be seen that each row of pins includes: several connecting pins 2005.
[0094] Among them, a number of connecting pins 2005 are arranged along the length direction 1003 of the plug body 2001 at a preset target spacing.
[0095] In addition, when the male plug 200 is connected to the female socket 100, the connecting pins 2005 in the pin group can be inserted into the connecting slots 201 of the ground pin 21 and the signal pin 22 in the terminal group of the female socket 100.
[0096] In some embodiments, according to Figures 1-6 It can be seen that when the male plug 200 is connected to the female socket 100, the two second protrusions 2004 approach each other on the side of the length direction 1003 of the plug body 2001 and abut against the first protrusion 301 on the first isolation piece 3 of the female socket 100.
[0097] In some embodiments, refer to Figures 1-6 It can be seen that the second isolation hole 2002 passes through the plug body 2001 on both sides of its length direction 1003, and the shape and size of the second isolation hole 2002 are adapted to the second isolation piece 2003.
[0098] In some embodiments, please continue to refer to Figures 1-6 The plug body 2001 has a second groove 2006 and two rows of mounting slots 2007.
[0099] Among them, the two rows of mounting slots 2007 are symmetrical about the second isolation hole 2002 in the width direction 1001 of the plug body 2001, and each row of mounting slots 2007 is composed of a number of mounting slots 2007 arranged along the length direction 1003 of the plug body 2001 at a preset target spacing.
[0100] In addition, the connecting pins 2005 are all fixed in the mounting groove 2007, and the protruding direction of the connecting pins 2005 is the same as the opening direction of the second groove 2006.
[0101] Furthermore, when the male plug 200 is connected to the female socket 100, the protrusion 103 on the socket body 1 of the female socket 100 is accommodated in the second groove 2006.
[0102] In summary, the female socket and electrical connector assembly provided in this embodiment of the invention utilize a first insulating plate to achieve mutual isolation between the two rows of terminal groups, effectively preventing crosstalk between signal pins in the two rows of terminal groups.
