Description

Technical Field

[0001] The present invention relates to the technical field of electrical connectors, and in particular to a plug-in female connector. Background Art

[0002] Plug-in electrical connectors are electronic components used to achieve electrical connections. They are used in various electrical devices to facilitate wiring. They serve as a bridge between blocked circuits or independent circuits, and are responsible for current or signal transmission. They can also be used in conjunction with electrical terminals to form a board-to-line connection. They can also be used independently to connect boards to boards. Plug-in electrical connectors are widely used in various fields, such as automobiles, electric vehicles and other motor vehicles, and various electronic equipment fields to connect various electrical components.

[0003] The plug-in female connector is a key component in the connector system. It cooperates with the male connector through plug-in and pull-out actions to achieve convenient connection and disconnection of the circuit. The traditional plug-in female connector is usually composed of a plastic shell, a terminal built into the plastic shell, and a spring. These components work together: the spring and the terminal are tightly matched to firmly clamp the conductive element (such as a cable) inserted into the plastic shell, thereby ensuring reliable transmission of electrical signals between the conductive element and the terminal.

[0004] The cooperation between the spring clip and the terminal is to clamp the conductive element between the spring clip and the terminal through the elastic properties of the spring clip, so as to fix the conductive element. However, since the plug-in female connector is plugged in and out many times during use, the spring clip will be used for a long time to clamp the conductive element and be squeezed many times. The elastic properties of the spring clip will gradually deteriorate or fail in this case. Therefore, the service life of the spring clip is short. Summary of the invention

DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] Reference Figures 1 to 6The pluggable female connector of the present invention includes a plastic shell 1, a terminal assembly 2 installed in the plastic shell 1, and an elastic compensation part 3 installed on the terminal assembly 2. The plastic shell 1 is used to insulate and protect the terminal assembly 2. The terminal assembly 2 is used to cooperate with the male terminal of the docking male connector to achieve electrical connection, and the terminal assembly 2 is used to be detachably connected to an external conductive element such as a cable, so as to clamp and fix the conductive element or loosen the conductive element.

[0028] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the plastic shell 1 is a geometric three-dimensional structure. In the embodiment, the plastic shell 1 is composed of at least one cubic structure and is adapted to be set in the terminal assembly 2. In another embodiment, the plastic shell 1 is a prismatic structure and is adapted to be set in the terminal assembly 2. In this embodiment, the plastic shell 1 is made of an insulating material such as plastic injection molding. In order to facilitate the understanding of this structure, the present invention is marked with a first side direction, a second side direction perpendicular to the first side direction, a third side direction perpendicular to the second side direction, and a fourth side direction perpendicular to the third side direction. The first side direction and the fourth side direction are parallel, and the second side direction and the third side direction are parallel. Among them, the plastic shell 1 has a length, a width, and a height. The first side and the fourth side are parallel to the direction of the height, and the second side and the third side are parallel to the direction of the width.

[0029] In this embodiment, the plastic housing 1 includes a main body 11 and a cover 12. The main body 11 is hollowed to form a plug-in cavity 13. The terminal assembly 2 is used to be installed in the plug-in cavity 13. For the convenience of installation, the plug-in cavity 13 is penetrated toward the first side so that the plug-in cavity 13 is open toward the first side. The cover 12 is used to cover the open side of the plug-in cavity 13, so that the cover 12 can be removed during installation, and the terminal assembly 2 is inserted into the plug-in cavity 13. Then, the cover 12 is used to cover the open side of the plug-in cavity 13 to prevent the terminal assembly 2 from being separated from the plug-in cavity 13, so as to achieve a detachable connection of the terminal assembly 2. For the convenience of understanding, the main body 11 has a first surface 141 distributed toward the first side and a second surface 142 distributed toward the fourth side. The first surface 141 and the second surface 142 are relatively distributed and both refer to the outer side of the main body 11. The plug-in cavity 13 penetrates the first surface 141 toward the first side to form an open side 13a. The plug-in cavity 13 includes an assembly cavity section 131 close to one side of the first surface 141, a close-fitting cavity section 132 located in the middle, and a docking cavity section 133 close to one side of the second surface 142. The assembly cavity section 131 is located on the first side of the close-fitting cavity section 132, and the docking cavity section 133 is located on the fourth side of the close-fitting cavity section 132. The assembly cavity section 131, the close-fitting cavity section 132, and the docking cavity section 133 are arranged and connected in sequence, and the open side 13a is formed on one side of the assembly cavity section 131 facing the first side. Among them, the assembly cavity section 131 is wider than the close-fitting cavity section 132, and the cavity wall on one side of the assembly cavity section 131 close to the close-fitting cavity section 132 and facing the fourth side is defined as the first side wall 1311. The width of the tight-fitting cavity section 132 and the docking cavity section 133 can be the same, and the width of the docking cavity section 133 can also be slightly smaller than the tight-fitting cavity section 132. The corresponding end of the terminal assembly 2 can penetrate into the tight-fitting cavity section 132 and the docking cavity section 133, and the first side wall 1311 can limit the other end of the terminal assembly 2 from continuing to move toward the tight-fitting cavity section 132 and the docking cavity section 133. Correspondingly, the main body 11 has a plug-in portion 11a and an assembly portion 11b, and the assembly portion 11b is located on the first side of the plug-in portion 11a. When the female connector is mated with the docking male connector, the plug-in portion 11a approaches the male connector toward the fourth side and is plugged into the male connector. A second socket 144 connected to the docking cavity section 133 is provided at a position on the second surface 142 corresponding to the terminal assembly 2. The second socket 144 passes through the second surface 142 toward the first side and is connected to the docking cavity section 133. The second socket 144 is used for the docking male terminal to pass through and penetrate into the docking cavity section 133, so that the docking male terminal can dock with the terminal assembly 2 to realize the transmission of electrical signals.

[0030] Please refer to Figure 1 and Figure 2In the embodiment shown, elastic buckle structures 15 are formed on the outer side walls of the plastic housing 1 on both sides, wherein the elastic buckle structures 15 are formed on the main body 11 and located on the two outer side walls of the main body 11 arranged along the length direction. The elastic buckle structure 15 includes a first clamping portion 151 integrally connected to the outer side wall of the main body 11 and a limiting portion 152 integrally connected to the outer side wall of the main body 11. The first clamping portion 151 is used to elastically clamp with the docking male connector to achieve the connection between the two, and the limiting portion 152 prevents the first clamping portion 151 from excessive movement and avoids the first clamping portion 151 from breaking. In the content defined in this embodiment, the first clamping portion 151 includes two parallel and spaced first extension plates 1511, second extension plates 1512 integrally connected to the two first extension plates 1511 on both sides, an elastic plate 1513 extending from the second extension plate 1512 in a direction parallel to the first extension plate 1511, and a first buckle 1514 formed on the side of the elastic plate 1513 away from the main body 11. Since the main body 11 is plugged into the docking male connector toward the first side, one of the two first extension plates 1511 is toward the second side, and the other is toward the third side, with the second extension plate 1512 connected to one end of the two first extension plates 1511 toward the fourth side, and the elastic plate 1513 is formed by extending from one side of the second extension plate 1512 toward the first side, and the elastic plate 1513 is located between the two first extension plates 1511. Spacing grooves 1515 are formed on both sides of the elastic plate 1513 and between the two first extension plates 1511, and a second activity space is formed between the elastic plate 1513 and the outer side wall of the main body 11, so that the elastic plate 1513 can swing inward and outward toward the second activity space by utilizing the elastic properties of the plastic itself. The first buckle 1514 is formed on the side of the elastic plate 1513 facing away from the second activity space, and the first buckle 1514 is a wedge-shaped structure that gradually widens toward the first side, and has a first guiding slope on the first buckle 1514. Among them, the first extension plate 1511 is connected to one end of the second extension plate 1512, and the second extension plate 1512 and the first buckle 1514 are all located on the plug-in portion 11a, so as to be inserted into the docking male connector. The first guiding slope is pressed against the inner wall of the docking male connector when inserted into the docking male connector, so that the elastic plate 1513 can be deformed toward the second activity space, so that the first buckle 1514 can pass through the inner wall of the male connector, until the first buckle 1514 is stuck in the corresponding groove structure, and the first buckle 1514 connects the plug-in portion 11a with the male connector and then locks it. A pressing block 1516 is protruded from one end of the elastic plate 1513 toward the first side and away from the main body 11. The pressing block 1516 is located on the assembly portion 11b of the main body 11 so as to be located outside the male connector when the main body 11 is plugged into the male connector.The pressing block 1516 can be manually pressed to deform the elastic plate 1513 toward the second movable space when the main body 11 is plugged into the male connector, thereby facilitating the first buckle 1514 to move through the inner wall of the male connector. When the connected plastic shell 1 and the male connector are disassembled, the first buckle 1514 can be easily disassembled by pressing the pressing block 1516 again to disengage the first buckle 1514 from the groove structure on the male connector. The elastic plate 1513 may be limited in outward movement during use, that is, deformed toward the side away from the main body 11. Since the elastic plate 1513 is not restricted in the direction away from the main body 11, and the elastic buckle structure 15 is integrally formed with the main body 11 and is also made of plastic, the elastic plate 1513 is prone to breakage. To this end, the limiting portion 152 is formed on one end of the two first extension plates 1511 facing the first side, and the two limiting portions 152 include a third extension plate 1521 extending from the first extension plate 1511 toward the side away from the main body 11. The two third extension plates 1521 extend toward each other to form baffles 1522. The two baffles 1522 are spaced apart and form a third activity space 1523. The pressing block 1516 is in the third activity space 1523 and can move freely in the third activity space 1523. The pressing block 1516 is narrower than the elastic plate 1513, the width of the elastic plate 1513 is greater than the width of the third activity space 1523, and one end of the elastic plate 1513 facing the first side is located in the two third extension plates 1521 in the main body 11, so that the elastic plate 1513 can deform outward at most to stop at the two baffles 1522.

[0031] In this embodiment, in order to facilitate the connection between the cover 12 and the main body 11, a connection structure is formed between the main body 11 and the cover 12 to connect the cover 12 to the main body 11 to limit the terminal assembly 2. The connection structure includes a connection enclosure 161 extending from at least one opposite side edge of the first surface 141 of the main body 11 toward the first side direction, a card slot 162 formed on the inner side wall of each connection enclosure 161, and a second buckle 163 convexly provided on the outer side wall of the cover 12 at the position corresponding to each card slot 162. In this embodiment, in this embodiment, at least two terminal assemblies 2 are provided, and at least two plug-in cavities 13 are provided corresponding to the terminal assemblies 2, and at least two second sockets 144 are also provided corresponding thereto, that is, each terminal assembly 2 has a separate plug-in cavity 13 and a second socket 144 corresponding thereto, and each plug-in cavity 13 is arranged in sequence along the length direction of the plastic housing 1. The connection enclosure 161 is provided with two, which are respectively provided on one side edge of the first surface 141 facing the second side direction and on one side edge facing the third side direction. An installation space is formed between the two connecting panels 161, and the length, width and height of the installation space are respectively adapted to the length, width and height of the cover body 12, so that the cover body 12 can be inserted into the inner side of each connecting panel 161. A card slot 162 is provided on each connecting panel 161 corresponding to a plug-in cavity 13, that is, the number of card slots 162 on the two connecting panels 161 is the same as the number of plug-in cavities 13. The position and number of the second buckles 163 are arranged corresponding to the card slots 162. The second buckle 163 is wedge-shaped and gradually widens toward the first side and also has a second guiding inclined surface. During assembly, the cover 12 is inserted into the installation space, and the second buckle 163 is gradually squeezed and inserted into the card slot 162 during the installation process. Since the side of the connecting panel 161 facing the first side is relatively independent, during the installation of the cover 12, the second buckle 163 is squeezed on the inner side of the connecting panel 161, and the connecting panel 161 is squeezed outward to a certain extent, so that the second buckle 163 can be squeezed into it until it penetrates into the card slot 162 to achieve locking. The cavity wall between any two adjacent plug-in cavities 13 is defined as a partition 171. In order to increase the connection stability and firmness between the cover 12 and the main body 11, the connection structure also includes a rib groove 164 recessed on the side of the cover 12 facing the first surface 141 of the main body 11, the number of the rib grooves 164 is the same as the number of the partitions 171 and is opened opposite to each other, the rib grooves 164 are penetrated toward the fourth side, and the rib grooves 164 are respectively penetrated toward the second side and the third side. The rib groove 164 divides the side of the cover 12 facing the main body 11 into a plurality of mating surfaces 134. When the cover 12 is placed on the first surface 141 and the second buckle 163 is inserted into the slot 162, the side of the partition 171 facing the first side is inserted into the rib groove 164, and each mating surface 134 extends into each insertion cavity 13.The cover 12 is provided with a first socket 143, the number and position of which correspond to each plug-in cavity 13 and are open toward the first side and the fourth side for the cables to pass through. In this embodiment, a limiting groove 172 is recessed on the mating surface 134 of the cover 12. When the terminal assembly 2 is installed in the main body 11, the cover 12 is placed on the main body 11 to block the open side 13a of the plug-in cavity 13. At the same time, the end of the terminal assembly 2 extends into the limiting groove 172, and the limiting groove 172 presses against the terminal assembly 2 toward the inner wall of the first side, thereby further limiting the terminal assembly 2, preventing the terminal assembly 2 from moving toward the first side, and limiting the terminal assembly 2 from moving toward the second side or the third side to a certain extent. In another embodiment, the terminal assembly 2 can be set to one, and the plug-in cavity 13, the first socket 143 and the second socket 144 are each set to only one; the connecting panel 161 can be set to two or four. When there is only one plug-in cavity 13, there is no need to set the rib groove 164.

[0032] Please refer to Figure 2 , Figure 4 , Figure 5 and Figure 6 The terminal assembly 2 includes a metal terminal 21 and a spring 22, both of which can be inserted into the plug-in cavity 13, wherein the metal terminal 21 is inserted into the plug-in cavity 13, and the spring 22 and the elastic compensation portion 3 are installed in the plug-in cavity 13. The spring 22 has a first end 22a and a second end 22b, wherein the first end 22a extends toward the metal terminal 21 and intersects the metal terminal 21, and the first end 22a is movably connected to the metal terminal 21, so that the first end 22a can move relative to the metal terminal 21, or the metal terminal 21 can move relative to the first end 22a. The second end 22b is bent from the first end 22a and intersects with the first end 22a and abuts against the metal terminal 21, so that a first movable space 226 is formed between the inner sides of the spring sheet 22. The first movable space 226 enables the first end 22a to move relative to the metal terminal 21, and when the first end 22a moves after being squeezed, it cooperates with the metal terminal 21 to restrict or loosen the conductive element, and the second socket 144 faces the metal terminal 21 toward the fourth side; the elastic compensation part 3 is installed in the first movable space 226. When the first end 22a is squeezed, the first movable space 226 will gradually narrow, and the elastic compensation part 3 elastically supports the first end 22a, and compensates for its elastic characteristics on the premise that the first end 22a itself has a rebound characteristic, thereby improving the limiting cooperation effect between the first end 22a and the metal terminal 21 on the cable and improving the service life of the spring sheet 22.

[0033] In the content defined in this embodiment, the metal terminal 21 is made of a conductive metal material such as copper, and the metal terminal 21 includes a tight-fitting section 211 for being inserted and confined in the tight-fitting cavity section 132, a mating end 212 connected to one end of the tight-fitting section 211, and an elastic clamping end 213 connected to the other end of the tight-fitting section 211. During assembly, the mating end 212 is assembled in the assembly cavity section 131, the elastic clamping end 213 extends into the docking cavity section 133 and is aligned with the second socket 144, the tight-fitting section 211 is pressed against the cavity wall of the tight-fitting cavity section 132 to limit the movement of the metal terminal 21, the mating end is located in the assembly cavity section 131, and the spring sheet 22 is installed on the mating end 212 to be installed in the assembly cavity section 131 along with the metal terminal 21.

[0034] The tight-fitting section 211 includes a second side panel 2111, two third side panels 2112 that are bent from opposite sides of the second side panel 2111 and extend in the same manner, a fourth side panel 2113 that extends from a side of one of the third side panels 2112 away from the mating end 212 toward a fourth side direction, and two fifth side panels 2114 that extend in the same direction from both side edges of the fourth side panel 2113 itself in the width direction. The second side panel 2111 is arranged perpendicular to the second side direction and the third side direction, and the third side panels 2112 extend from both sides of the second side panel 2111 toward the third side direction, so that the tight-fitting section 211 has a U-shaped structure. Due to the elastic properties of its material itself, the size of the tight-fitting cavity section 132 is adapted to the tight-fitting section 211. When the tight-fitting section 211 is inserted into the tight-fitting cavity section 132, the two third side panels 2112 of the tight-fitting section 211 are pressed against the cavity wall of the tight-fitting cavity section 132.

[0035] The mating end 212 includes a first arm section 2121 bent and extended from one side of the tight-fitting section 211 toward the first side direction, a second arm section 2122 extending from the first arm section 2121 along the first side direction, and a third arm section 2123 bent and extended from the second arm section 2122. The second arm section 2122 is connected to a first side plate 2124 extending toward the third side direction on both side walls along the width direction of the second arm section 2122. A stopper 173 for limiting the movement of the first side plate 2124 toward the third side direction is convexly provided on the cavity wall where the assembly cavity section 131 is located toward the third side direction. After the tight-fitting section 211 of the metal terminal 21 is inserted into the tight-fitting cavity section 132, the first side plate 2124 is directed toward the third side direction. The first side plate 2124 can abut against the stopper 173, or a certain gap can be formed between the third side plate 2112 and the stopper 173. In this embodiment, the third arm segment 2123 includes a first arm segment 21231 extending toward the third side after being bent from the second arm segment 2122, a second arm segment 21232 extending toward the second side after being bent from one end of the first arm segment 21231 away from the second arm segment 2122, and a third arm segment 21233 extending toward the first side from one end of the second arm segment 21232 away from the first arm segment 21231, the first arm segment 21231 also tilts toward the first side at one end away from the second arm segment 21231, and the second arm segment 21232 also tilts toward the first side at one end away from the first arm segment 21231, so that the bending point 21234 is formed at the first arm segment 21231 and the second arm segment 21232, and the first socket 143 is arranged opposite to the bending point 21234. It should be noted that only "first side", "second side", "third side" and "fourth side" are written in the text, but they all refer to the directions indicated.

[0036] The elastic clamping end 213 includes two elastic arms 2131 extending from one side of the two fifth side plates 2114 away from the tight fitting section 211 toward the fourth side, and the two elastic arms 2131 are inclined toward each other and gradually narrowed toward the fourth side, and the two elastic arms 2131 are bent after approaching and continue to be inclined back to each other and gradually widened, so that the two elastic arms 2131 have abutting portions 2132 that are close to or close to each other. During assembly, one end of the elastic arm 2131 penetrates into the docking cavity section 133, and the two fifth side plates 2114 can be used to press against the cavity wall of the docking cavity section 133, and one end of the abutting portion 2132 is close to the second socket 144, and the male terminal to be docked penetrates into the docking cavity section 133 through the second socket 144 and squeezes into the space between the two elastic arms 2131, and the abutting portion 2132 presses against the male terminal to be docked.

[0037] In the content defined in this embodiment, the spring piece 22 is made of conductive metal such as stainless steel. The spring piece 22 includes a first arc section 221 with two ends bent toward the first side direction, a second arc section 222 extending from one end of the first arc section 221 toward the first side direction and then continuing to bend toward the third side direction, a matching section 223 extending from the second arc section 222 toward the third side direction, and a holding section 224 extending from the other end of the first arc section 221 toward one side of the matching section 223, and the second arc section 222 is inclined toward the second side direction, the matching section 223 is the first end 22a of the spring piece 22, and the holding section 224 is the second end 22b of the spring piece 22. A movable hole 225 is formed through the matching section 223. The movable hole 225 is through the first side direction and the fourth side direction and has a width greater than the width of the third arm section 2123. The abutting section 224 is movably inserted into the movable hole 225 so that the spring sheet 22 forms a closed loop of the first movable space 226. The third arm section 2123 of the metal terminal 21 is movably inserted into the movable hole 225 toward the first side direction. Preferably, the first arm section 21231 is partially located in the movable hole 225. The abutting section 224 is tightly pressed against the third arm section 2123. Preferably, one end of the abutting section 224 away from the first arc section 221 is pressed against the side of the inflection point 21234 toward the second side direction, so that the inflection point 21234 plays a certain limiting role on the abutting section 224. In this embodiment, when the abutting section 224 abuts against the third arm section 2123 and the third arm section 2123 passes through the third movable hole 225, the spring sheet 22 is in a squeezed state and the matching section 223 abuts against the third arm section 2123 toward the second side, thereby cooperating with the abutting section 224 to restrict the spring sheet 22 on the metal terminal 21. The matching section 223 is sleeved on the third arm section 2123 through the movable hole 225, thereby forming a clamping opening 227 between the matching section 223 and the metal terminal 21, the clamping opening 227 being formed by the end of the movable hole 225 facing the third side and the third arm section 2123, and the first socket 143 is arranged corresponding to the clamping opening 227. A pressing hole 145 penetrating the main body 11 is provided on the side wall of the assembly cavity section 131 facing the second side direction, and the pressing hole 145 is directly opposite to the second arc section 222, so that the second arc section 222 can be squeezed by the pressing hole 145, thereby prompting the matching section 223 to move toward the third side to enlarge the clamping opening 227, so as to allow the cable to pass through. When the second arc section 222 is released, the matching section 223 rebounds and moves toward the second side to clamp the cable together with the third arm section 2123. Among them, the space between the two first side plates 2124 can allow the cable to pass through, avoiding obstruction of the cable connection. In order to facilitate the installation of the matching section 223, there is a space between the stopper 173 and the matching section 223 for the matching section 223 to move toward the third side direction.

[0038] Please refer to Figure 2 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the elastic compensation part 3 is a rubber plug made of silicone or silicone rubber. The elastic compensation part 3 includes a base 31, a compensation part 32 extending from one end of the base 31 toward the first side direction toward the second side direction, and a support part 33 extending from the other end of the base 31 toward the third side direction toward the first side. The base 31 is semicircular as a whole and is arranged on the inner side of the first arc section 221. The side surface of the base 31 facing the fourth side has a first arc surface 311 that fits the first arc section 221. The two ends of the first arc surface 311 extend directly to the two ends of the base 31. The first arc section 221 provides support to the base 31 through the first arc surface 311, so that the base 31 can be installed in the first arc section 221 more stably. There is an escape space 34 between the compensation portion 32 and the support portion 33 for the compensation portion 32 to move. The compensation portion 32 is pressed against one end of the second arc section 222 connected to the matching section 223 to provide elastic support for the first end 22a of the spring piece 22 and enhance the fastening force of the first end 22a to the cable. The support portion 33 is arranged at intervals from the compensation portion 32. When the first end 22a of the spring piece 22 is squeezed to be supported on the support portion 33 before overpressure, the deformation of the first end 22a is limited to avoid the first end 22a from being deformed due to overpressure and unable to rebound, thereby increasing the use time of the spring piece 22 to a certain extent and improving the service life.

[0039] The compensation portion 32 includes a straight elastic section 321 extending from one end of the base 31 toward the first side direction and a curved elastic section 322 curved from the straight elastic section 321 toward the third side direction. The straight elastic section 321 is also inclined toward the second side direction relative to the base 31. The curved elastic section 322 is curved from one end of the straight elastic section 321 away from the base 31 toward the first side direction and then toward the third side direction. The end of the curved elastic section 322 away from the straight elastic section 321 is also curved and inclined toward the fourth side direction, so that the compensation portion 32 has a hook-shaped structure. The second arc section 222 is connected to one end of the first arc section 221 and forms an acute angle with the straight elastic section 321, so that the straight elastic section 321 is separated from the second arc section 222. Among them, the angle between the straight elastic section 321 and the second arc section 222 is usually less than 45° to prevent the size of the spring piece 22 from being too large. In this embodiment, the diameter of the circle corresponding to the curved elastic segment 322 is smaller than the diameter of the circle corresponding to the second arc segment 222. For this reason, one end of the curved elastic segment 322 away from the straight elastic segment 321 is pressed against the second arc segment 222 and mostly in a line contact manner, so that when the compensation portion 32 supports the first end 22a, it not only plays a supporting role, but also reduces the interference of the compensation portion 32 on the first end 22a during use, thereby reducing the action surface of the first end 22a on the curved elastic segment 322, thereby improving the service life of the support portion 33.

[0040] The support portion 33 extends from the base 31 toward the first side and is inclined relative to the base 31 toward the second side. A straight surface 331 is formed on one side of the support portion 33 toward the third side. An acute angle is formed between the straight surface 331 and the supporting section 224, so that when the first end 22a squeezes the compensation portion 32, the entire elastic compensation portion 3 can rotate around the first arc surface 311 to a certain extent after being squeezed without locking the elastic compensation portion 3. The curved elastic section 322 prevents the elastic compensation portion 3 from jumping, thereby ensuring the stability of the elastic compensation portion 3. The side of the support portion 33 facing the second side direction is spaced from the straight elastic segment 321 to form an avoidance surface 332. The end of the support portion 33 away from the base 31 is formed with a protruding end 333 protruding toward the side of the curved elastic segment 322 and spaced from the curved elastic segment 322. The protruding end 333 has a second arc surface 334 adapted to the curved elastic segment 322. The curved elastic segment 322 moves relative to the second arc surface 334 after being squeezed. The second arc surface 334 is located within the normal deformation range of the curved elastic segment 322 and the second arc segment 222, so that when the first end 22a is squeezed and moves until the curved elastic segment 322 abuts against the protruding end 333, the protruding end 333 supports it while preventing the curved elastic segment 322 from being over-pressed and deformed and damaged.

[0041] The working method of one embodiment of the pluggable female connector of the present invention is as follows: during assembly, first, the third arm segment 2123 is passed through the movable hole 225, the curved elastic segment 322 is located on the second side of the second arm segment 2122, the abutting section 224 and the mating section 223 cooperate with the third arm segment 2123 to install the spring sheet 22 on the mating end 212, the elastic compensation portion 3 is placed in the first movable space 226, one end of the abutting portion 2132 is facing the plug-in cavity 13, the spring sheet 22 is facing the second side, and the metal terminal 21 is facing the third side, and then the terminal assembly 2 is inserted into the plug-in cavity 13, and after the tight-fitting section 211 is against the cavity wall of the tight-fitting cavity section 132, the first side plate 2124 is close to the stopper 173, and the abutting portion 2132 is facing Toward the fourth side corresponding to the second socket 144, the curved elastic section 322 faces the second side corresponding to the pressing port 145, the spring sheet 22 and the elastic compensation part 3 are restricted by the cavity walls on both sides of the assembly cavity section 131, and after the spring sheet 22 is installed in the assembly cavity section 131, the gap between the two sides of the spring sheet 22 and the cavity walls on the opposite sides of the assembly cavity section 131 is not enough for the elastic compensation part 3 to pass through, so as to restrict the elastic compensation part 3 in the first activity space 226, and then the cover body 12 is covered on the main body 11, so that the first socket 143 faces the fourth side corresponding to the matching section 223, the limiting groove 172 presses the third arm section 2123, the matching surface 134 extends into the assembly cavity section 131, and the partition 171 is inserted into the rib groove 164 toward the side of the first side. When in use, the second arc section 222 is pressed from the pressing port 145 to move the mating section 223 toward the third side to open the clamp 227, and then the clamp 227 is kept open. After the cable passes through the clamp 227 via the first socket 143, the second arc section 222 is released, and the second arc section 222 rebounds and presses against the cable. The plug-in part 11a of the main body 11 is inserted into the docking male connector, so that the male terminal passes through the second socket 144 and is clamped in the supporting portion 2132, thereby realizing the circuit connectivity of the female connector of the present invention.
