For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0060] Figure 1 is a structural diagram of the connector. Figures 2-3 is an explosion diagram of the connector in different directions. The connector in the figure can connect multiple wires at the same time. The connector can be used to realize the requirements of the video card on the transmission of the Peripheral Component Interconnect Express (PCI Express) standard. The advantages of this standard are high data transmission rate, strong anti-interference ability, long transmission distance, low power consumption, etc. The smaller 4 pins at the top of the connector in the figure are signal pins, and the larger 12 pins are power supply pins. On the contrary, Figures 4-6 respectively shows three different wire connection modes, which are connected at the opposite end of the connector and the pin.

[0061] In some embodiments, as Figures 1-6As shown, the terminal electrically includes a first connecting segment 2 and a mating segment 1 electrically connected to each other. The mating segment 1 has a bottom wall, both sides of the bottom wall extend upwardly to form side walls, the upper ends of the two side walls extend toward each other to form a top wall, and the bottom wall, the side walls and the top wall together form a channel; the channel can be used to accommodate at least part of the male terminal subsequently; the mating segment 1 includes a base area 16, a connecting area 17 and an interface area 18; the base area 16 is connected to the first connecting segment 2, and the connecting area 17 is connected between the interface area 18 and the base area 16;

[0062] Both side walls of the base area 16 are provided with a rectangular clearance hole 161, and a retreat prevention arm 162 is arranged in the rectangular clearance hole 161. The retreat prevention arm 162 has a fixed end and a free end, the fixed end of the retreat prevention arm 162 is connected to one end of the rectangular clearance hole 161 close to the connecting area 17, and the retreat prevention arm 162 is away from the channel direction from the fixed end to the free end direction; further, the width of the retreat prevention arm 162 is less than the width of the rectangular clearance hole 161; the length of the retreat prevention arm 162 is less than the length of the rectangular clearance hole 161; specifically, the terminal is installed in the insulator socket, and the retreat prevention arm 162 cooperates with the insulator socket. After the terminal is inserted into the insulator socket, the terminal is prevented from being withdrawn from the insulator socket, and the stability of use is ensured.

[0063] In another embodiment of the present application, the retreat prevention arm 162 is arranged in the center of the rectangular clearance hole 161, so that the retreat prevention arm 162 cooperates with the insulator socket to make the base area 16 bear force uniformly and prevent the terminal from being deviated.

[0064] In another embodiment of the present application, the retreat prevention arm 162 includes a first retreat prevention part 1621 and a second retreat prevention part 1622; the first retreat prevention part 1621 is connected between the rectangular clearance hole 161 and the second retreat prevention part 1622, and the first retreat prevention part 1621 is parallel to the channel; further, the connection between the first retreat prevention part 1621 and the second retreat prevention part 1622 is an arc surface structure. Specifically, the second retreat prevention part 1622 is deformed by force, the force is transmitted to the first retreat prevention part 1621, the first retreat prevention part 1621 can buffer the force, further improve the deformation ability of the retreat prevention arm 162, and reduce the phenomenon that the retreat prevention arm 162 is easily broken by force; improve the stability of the terminal in use.

[0065] In another embodiment of the present application, the connecting region 17 comprises at least two connecting region side walls 11, and a plurality of clamping pairs 12 arranged on the connecting region side walls 11, each of the clamping pairs 12 extends along the circumference of the channel 13, and each of the clamping pairs 12 is staggered along the axis of the channel 13 on the two connecting region side walls 11. Specifically, the plug moves along the channel, sequentially passes through the staggered clamping pairs 12, by arranging a plurality of clamping pairs 12, compared with the traditional arrangement of one clamping pair 12, the contact area between the clamping pair 12 and the plug is reduced, that is, the resistance of the plug inserted into the channel is reduced, so that the plug is more easily inserted into the channel 13, and excessive force can be prevented from causing wear between the plug and the clamping pair 12, further improving the stability of use.

[0066] In another embodiment of the present application, the clamping pair 12 comprises an upper cantilever contact 12a and a lower cantilever contact 12b; the upper cantilever contact 12a and the lower cantilever contact 12b are arranged on the connecting region side wall 11 in opposite circumferential directions of the channel 13.

[0067] Further, define two connecting region side walls 11 as a first connecting region side wall 111 and a second connecting region side wall 112; one end of the upper cantilever contact 12a is fixed to the upper end of the first connecting region side wall 111, the other end of the upper cantilever contact 12a extends towards the second connecting region side wall 112 and has a gap with the second connecting region side wall 112;

[0068] One end of the lower cantilever contact 12b is fixed to the lower end of the second connecting region side wall 112, and the other end of the lower cantilever contact 12b extends towards the first connecting region side wall 111 and has a gap with the first connecting region side wall 111.

[0069] Specifically, each cantilever contact is arranged in sequence, and when the plug is inserted into the channel 13, each cantilever contact can be sequentially fixed to the plug as the plug continuously deepens, making the insertion of the plug more smooth. On the other hand, it also avoids that when the cantilever contact is only one, the lateral pressure on the plug is too large, which makes the plug not easy to insert. At the same time, when the cantilever contact loses the elastic deformation ability, the electrical connection of the terminal cannot be guaranteed.

[0070] It should be noted that the length of the two connecting region side walls 11 can be determined according to the length of the channel 13, for example, when the plug is long, the length of the two connecting region side walls 11 is correspondingly configured to be extended, at the same time, the channel 13 extends in a straight line, and the cross-sectional shape in the extension direction can be adapted to the cross-sectional shape of the plug. For example, the cross section of the channel 13 is set to be circular or square, etc. Figure 4As shown, the shape of the port of the channel 13 arranged upward is roughly square; further, the number of each clamping pair 12 arranged includes but is not limited to two pairs. Different numbers of clamping pairs 12 can be adapted according to different needs.

[0071] In another embodiment of the present application, there is a gap between adjacent clamping pairs 12.

[0072] In another embodiment of the present application, the upper cantilever contact 12a and the lower cantilever contact 12b each include a curved section 121 and an extension section 122, the curved section 121 being connected between the extension section 122 and the connecting area side wall 11; specifically, the curved section 121 arranged improves the elastic deformation ability of the extension section 122, so that the upper cantilever contact 12a and the lower cantilever contact 12b are more stable in fastening with the plug. The extension section 1224 can adopt a planar structure or an arc-shaped structure to further increase the fastening of the plug. It should be noted that the arc shape here can be any curved section, for example, it can be V-shaped, U-shaped, etc.

[0073] In another embodiment of the present application, the length of the extension of the upper cantilever contact 12a and the lower cantilever contact 12b is greater than two-thirds of the distance between the two connecting area side walls 11. This ensures that the upper cantilever contact 12a and the lower cantilever contact 12b have sufficient contact area with the plug, and at the same time, ensures that the upper cantilever contact 12a and the lower cantilever contact 12b have sufficient elastic deformation space.

[0074] In another embodiment of the present application, the inner side of the first connecting area side wall 111 and the second connecting area side wall 112 is provided with a protruding structure 117; specifically, the protruding structure 117 arranged is for subsequent plug contact, further, the positionally opposite protruding structures 117 can correspond to or be staggered with each other.

[0075] In another embodiment of the present application, the end of the interface area 18 facing away from the connecting area 17 is configured to be slightly inclined towards the inside of the channel (as shown in the top of the figure Figure 8 , so that after the plug is inserted, it can play a guiding role for the plug; further, the interface area 18 includes an interface area bottom wall 181, an interface area side wall 182 and an interface area top wall 183; the interface area side wall 182 is connected with the connecting area 17 respectively, the interface area bottom wall 181 is arranged at the bottom of the interface area side wall 182, and the interface area top wall 183 is arranged at the top of the interface area side wall 182; the interface area top wall 183 is provided with a frame opening slot, which is arranged along the axial direction of the channel 13; the frame opening slot is a straight line, a curve or a combination of the two; it should be noted that the curve here includes but is not limited to an S-shaped curve, a sawtooth curve and a wave-shaped curve.

[0076] In another embodiment of the present application, the base area 16 is further provided with a limiting arm 163, which is close to the first connecting section 2. Specifically, the limiting arm 163 is configured to avoid excessive insertion when the terminal is mounted in the insulator socket, thereby protecting the terminal and the insulator socket.

[0077] Figures 7-8 is a terminal with a protection function, and the structural schematic views in different directions. Figure 9 is a cross-sectional view at B-B in Figure 8 . The area III shown in Figure 8 is an upper cantilever contact 12a that needs to be protected. The upper cantilever contact 12a is located at a position away from the port 131 of the channel 13.

[0078] In another embodiment of the present application, as shown in Figures 1-9 , at least two of the connecting area side walls 11 are defined as a first connecting area side wall 111 and a second connecting area side wall 112. The terminal further comprises a second connecting section 3, the abutting section 1 is electrically connected to the first connecting section 2 through the second connecting section 3, and the side of the channel 13 away from the second connecting section 3 has a port 131. The abutting section 1 comprises a driving member 113, a driven member 114, and a first limiting member 115, which are arranged on the connecting area side wall 11 and extend along at least part of the circumferential direction of the channel 13. The driving member 113 is located at the position of the port 131 and is adjacent to the upper driven member 114 in the extension direction of the channel 13. The driven member 114 has a first clamping groove 1141, and the driving member 113 and the driven member 114 are connected to the first connecting area side wall 111. One end of the first limiting member 115 is connected to the second connecting area side wall 112 and the other end extends in the opposite direction of the driven member 114 and is lapped on the bottom edge of the first clamping groove 1141. The first limiting member 115 has an elastic deformation amount bending towards the inside of the channel 13. The terminal further comprises a connecting portion 14 connected to the driving member 113 and the driven member 114. The driving member 113 is configured to drive the driven member 114 to expand away from the channel 13 when a contact with a diameter larger than a predetermined diameter is inserted into the channel 13, so that the first limiting member 115 slides out of the first clamping groove 1141 and falls into the channel 13.

[0079] Specifically, the first clamping groove 1141 is opened towards the outside of the channel 13. It has a notch towards the first limiting member 115, which allows the first limiting member 115 to be inserted into the first clamping groove 1141 from the side. The connecting portion 14 is substantially a cuboid and is connected to the opposite sides of the driving member 113 and the driven member 114.

[0080] In order to stably fix the plug, the number of the clamping pairs 12 is multiple and is arranged at intervals in the above embodiment. The embodiment can play a protection role for the clamping pairs 12 at the bottom of the channel 13. When the operator assembles or tests, two similar plugs can be mixed, so that the plug with a larger diameter is inserted into the terminal. Or when the plug is inserted, the plug is not inserted into the terminal along the extension direction of the channel 13. In the above two cases, the clamping pairs 12 will be affected, so that the elastic deformation amount will be reduced or even completely disappear. At this time, the terminal cannot tightly fix the plug, and finally leads to the communication interruption between the electronic devices.

[0081] In the embodiment, when the plug with a larger diameter is inserted into the channel 13, the driving piece 113 is first lifted to the outside of the channel 13, and the driven piece 114 is also lifted to the outside under the drive of the connecting part 14. At this time, the first limiting piece 115 which is overlapped with the driven piece 114 is also lifted to the outside. Here, the overlapping position of the first limiting piece 115 and the driven piece 114, that is, the contact area of the first limiting piece 115 and the bottom of the first clamping groove 1141 is configured to be small, so that the first limiting piece 115 can slide out of the first clamping groove 1141 only after moving a small distance with the driven piece 114 which expands to the outside. Then, the first limiting piece 115 is bent to the inside of the channel 13 under the action of the elastic deformation of itself (as shown by the arrow A in Figure 7 In the process, when the plug does not reach the clamping pair 12 in the region III, the first limiting piece 115 can limit the plug, and the plug will be hindered by the first limiting piece 115 in the process of insertion to prevent it from continuing to penetrate.

[0082] It is easy to understand that in order to balance the elastic force of the first limiting piece 115 with the elastic force of the driving piece 113 and the driven piece 114, the thickness of the first limiting piece 115 can be configured to be thinner and the width can be configured to be narrower. At the same time, in order to maintain the elastic force of the first limiting piece 115 to the inside, the inside and the outside surface of the first limiting piece 115 can be subjected to laser quenching treatment.

[0083] Preferably, the top of the first limiting piece 115 is further provided with a clamping hook 1151 (as shown in the enlarged view in Figure 9 The protruding height of the clamping hook 1151 can be adapted to the distance from the bottom of the first clamping groove 1141 to the inner wall of the channel 13. Thus, the clamping hook 1151 can limit the plug with a larger diameter. At the same time, when the plug matched with the channel 13 is inserted, the clamping hook 1151 can be retracted to the outside of the channel 13 to avoid interference.

[0084] In another embodiment of the application, as shown in Figures 1-9As shown, the docking section 1 further comprises a fixed part 116 corresponding to the driving part 113, which is located on the second connecting area side wall 112 and extends in the opposite direction of the driving part 113, and has a second clamping groove 1161 on the side facing the channel 13. The terminal comprises a second limiting part 15, one end of which is connected to the first connecting area side wall 111 and the other end extends towards the fixed part 116 and overlaps the bottom of the second clamping groove 1161, and the second limiting part 15 has a bending elastic deformation amount towards the outside of the channel 13. The driving part 113 has a protrusion 1131 on the side facing the channel 13. The overlapping area of the second limiting part 15 and the second clamping groove 1161 is larger than the overlapping area of the first limiting part 115 and the first clamping groove 1141.

[0085] Figure 9 As shown in the figure, region I and region II are shown, the overlapping area of the second limiting part 15 and the second clamping groove 1161 is region II in the figure, and the overlapping area of the first limiting part 115 and the first clamping groove 1141 is region I in the figure. In this embodiment, by setting region II to be larger than region I, after the first limiting part 115 and the first clamping groove 1141 are separated from each other, the second limiting part 15 and the second clamping groove 1161 can still be in an overlapping state. Thus, after the plug-in part is pulled out of the channel 13, the driven part 114 can be reset by the elastic deformation force of the second limiting part 15, and finally the first limiting part 115 can be re-overlapped in the first clamping groove 1141.

[0086] It is easy to understand that in the above embodiment, after the plug-in part is pulled out of the channel 13, it is difficult to reset into the first clamping groove 1141. At this time, the first limiting part 115 will abut against a position away from the bottom of the first clamping groove 1141. That is, the driven part 114 cannot be reset to the original position at this time. Therefore, in this embodiment, the elastic deformation amount of the second limiting part 15 is used to re-overlap the first limiting part 115 in the first clamping groove 1141. Meanwhile, in this embodiment, a protrusion 1131 is provided on the driving part 113, and not on the fixed part 116. The purpose is that when a plug-in part with a larger caliber enters the channel 13, the driving part 113 drives the driven part 114 to move outward. The fixed part 116 can still remain relatively stationary to avoid the second limiting part 15 from sliding out of the second clamping groove 1161 during this process.

[0087] In other embodiments, as shown by the dashed line in region IV, Figure 7 When the first limiting part 115 slides out of the first clamping groove 1141 or cannot be reset by the driving of the second limiting part 15, the operator can use the poking opening to move the position of the driving part 113, thereby manually resetting the first limiting part 115.

[0088] In another embodiment of the present application, the terminal further comprises a second connecting section 3, which is connected between the first connecting section 2 and the mating section 1.

[0089] In another embodiment of the present application, the first connecting section 2 is provided with a piercing portion extending away from the mating section 1, and the piercing portion is connected with the wire so that the included angle between the wire axis and the axis of the channel is close to or equal to 90 degrees.

[0090] In another embodiment of the present application, the first connecting section 2 and the second connecting section 3 have an included angle close to or equal to 90 degrees.

[0091] In another embodiment of the present application, the first connecting section 2 is provided with a wire fixing portion and a core fixing portion on both sides away from the second connecting section 3. Specifically, the wire fixing portion is used to fix the wire, and the core fixing portion is used to fix the core of the wire. Since the included angle between the first connecting section 2 and the second connecting section 3 is close to or equal to 90 degrees, the included angle between the wire axis and the axis of the channel is close to or equal to 90 degrees, and the space occupied by the wire is reduced when the wire needs to be bent and assembled.

[0092] In another embodiment of the present application, the first connecting section 2 is provided with a plurality of soldering grooves on the side away from the second connecting section 3. Specifically, the core of the wire is placed on the first connecting section, and then soldered on the first connecting section 2 through the solder paste. The first connecting section 2 is provided with a plurality of soldering grooves, which improves the connection stability of the first connecting section 2 and the core of the wire after soldering.

[0093] The present application further provides a socket comprising the above-mentioned electrical terminal.

[0094] Specifically, since the above-mentioned electrical terminal is used, when the plug-in part moves in the channel 13, it sequentially passes through the staggered clamping pairs 12. By arranging a plurality of clamping pairs 12, compared with the traditional arrangement of one clamping pair, the contact area between the clamping pair 12 and the plug-in part is reduced, that is, the resistance of the plug-in part inserted into the channel 13 is reduced, so that the plug-in part is more easily inserted into the channel 13, and the wear between the plug-in part and the clamping pair 12 caused by excessive force is prevented, further improving the stability of use.

[0095] In another embodiment of the present application, the socket further comprises a base 4, a body 5 and signal terminals, the body 5 is buckled with the base 4, and the base 4 is provided with a wire outlet 52 on one side; the base 4 further comprises a plurality of bosses, the height of each boss sequentially decreases towards the wire outlet; each boss is provided with a socket, and the electrical terminals and the signal terminals are installed in the corresponding sockets; specifically, during assembly, the signal terminals are installed in the sockets of the bosses with the lowest height, and then the electrical terminals are installed in the sockets of the bosses with increasing height, and finally the cover plate is buckled with the base; after the sockets of the bosses are opened and the terminals are installed in the sockets, the effect of limiting is achieved, without the need for additional limiting parts, and the height of the bosses decreases along the wire outlet, so that the wires of the previous row will not affect the assembly of the wires of the subsequent row.

[0096] In other words, the side wall of the socket 51 close to the wire outlet 52 is a first side wall 511, and the bottom height of the first side wall 511 close to the wire outlet 52 is greater than the bottom height of the first side wall 511 away from the wire outlet 52. Figures 2-3 The middle shows that the sockets 51 have three rows. And the distance from the bottom of the first side wall 511 on the right to the base 4 (the first row of four sockets) is greater than the distance from the bottom of the first side wall 511 on the left to the base 4 (the third row of six sockets). Among them, the distance from the bottom of the first side wall 511 in the middle to the base 4 is between the two (the second row of six sockets). Thus, the plurality of wires are arranged in three layers in height, and the connection direction of the three rows of wires can be turned to the upward direction after being connected with the terminals. In combination with Figure 2 It can be seen that in order to make the connection port more processed and integrated, the top height of the second row and the third row of sockets is configured to be consistent. For this purpose, the size of the terminals inside also needs to be adjusted accordingly, that is, the size of the terminals of the second row is set to be smaller than the size of the terminals of the third row.

[0097] In another embodiment of the present application, the height difference between adjacent bosses is greater than or equal to the outer diameter of the wire, so that the space for installing the wire can be reserved, so that each wire will not be excessively squeezed.

[0098] Further, for the piercing type connection terminals, the boss is further provided with a lower limiting part 55 for limiting the wire, and similarly, the body is provided with an upper limiting part 54 matched with the lower limiting part.

[0099] In another embodiment of the present application, the lower end of each of the insertion holes is provided with a guide inclined surface 512; the insertion hole 51 is provided with a retreat-preventing groove 513 which is adapted to the retreat-preventing arm 162, and the retreat-preventing groove 513 is provided with a clamping block, the lower end surface of the clamping block is an inclined surface structure, and the upper end surface of the clamping block is a flat surface structure. Specifically, the retreat-preventing arm 162 moves along the retreat-preventing groove 513 and along the inclined surface of the clamping block, the retreat-preventing arm 162 cooperates with the inclined surface of the clamping block to achieve a folding action, when the retreat-preventing arm 162 moves to the upper end of the clamping block, the retreat-preventing arm 162 loses the restriction of the inclined surface of the clamping block, thereby achieving a reset, and further making the lower end of the retreat-preventing arm 162 cooperate with the upper end of the clamping block to avoid the electrical terminal from withdrawing from the insertion hole.

[0100] In another embodiment of the present application, one side wall of the insertion hole 51 is further provided with a limiting groove 514 which is adapted to the limiting arm 163. Specifically, the limiting groove 514 cooperates with the limiting arm 163 of the electrical terminal to avoid the electrical terminal from further sliding upward along the insertion hole 51.

[0101] It should be noted that the structure of the connection of the signal terminal and the wire is the same as that of the electrical terminal and the wire, and the connection of the signal terminal and the insertion hole is the same as that of the electrical terminal and the insertion hole, which will not be described in detail here.

[0102] In another embodiment of the present application, the base 4 is provided with a plurality of protruding buckles, and the body 5 is provided with recessed buckles which are adapted to the protruding buckles. In this way, the structure of buckling can facilitate disassembly and assembly.

[0103] In some embodiments, as shown in Figures 1-9 The plurality of insertion holes 51 are distributed towards the top of the body 5 in a rectangular array, and the bottom of the body 5 is buckled with the base 4 to form a wire outlet 52 which is lateral to the insertion holes 51.

[0104] Specifically, the arrangement angle of the wire outlet 52 and the insertion hole 51 in the present embodiment can be adapted to the terminal. For example, when the arrangement angle of the first connecting segment 2 and the butt joint segment 1 is set to 90° or 120° after the second connecting segment 3 is bent, the arrangement angle of the wire outlet 52 and the insertion hole 51 can also be set to the corresponding degrees. In this way, by using the wire outlet 52 and the insertion hole 51 with angles, a smaller bending radius can be achieved at the position where the wire needs to be bent. The space is saved, and the mechanical properties of the wire are also protected.

[0105] In some embodiments, as shown in Figures 1-9 The base 4 includes a plurality of wire grooves 53 which are arranged along the transverse direction of the wire outlet 52, and the plurality of wire grooves 53 correspond to the plurality of insertion holes 51 which are away from one side of the wire outlet 52 in the rectangular array.

[0106] Specifically, Figure 4The specific structure of the wire slot 53 is shown in FIG. 5. The wire slot 53 is protruded on the base 4 away from the wire outlet 52. The wire slot 53 is used to accommodate the wire in the lowest layer of the wire harness. After passing through the wire slot 53, the wire is electrically connected to the terminal. Thus, the wire in the lowest layer is fixed by the wire slot 53, and the stability of the connection between the terminal and the wire is increased.

[0107] The terminal and the interface in the above embodiments can also be arranged in an electronic device, so as to connect the components in the electronic device or to test the electronic device by an operator. In an alternative implementation, as shown in FIG. 6, the electronic device includes the terminal and the interface in the above embodiments. The electronic device in this embodiment includes but is not limited to a desktop computer, a portable computer, a server computer, an artificial intelligence device, a medical device, etc. Figures 1-9

[0108] The electronic device in this embodiment uses the connection area side wall 11 extending along the channel 13 to guide the plug-in member, and uses the plurality of clamping pairs 12 extending along the circumference of the channel 13 to fasten the plug-in member. Thus, the stability of the connection between the terminal and the plug-in member is increased. When the plug-in member is inserted into the channel 13, the plurality of clamping pairs 12 arranged at intervals can fasten the plug-in member from different positions and different directions, so that the fastening is more stable. Meanwhile, when one of the clamping pairs 12 is damaged or loses elasticity, the remaining clamping pairs 12 can still fasten the plug-in member, so that the frequency of replacing the terminal is reduced, and the stability of the communication of the electronic device is improved.

[0109] The above description is only the preferred embodiments of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.​
