[0037] Referring to FIG. 1 and FIG. 2 , a plug structure 100 provided in an embodiment of the present application includes a housing 1100, a conductor 1200 and a sealing body 1300. The housing 1100 is provided with a cable cavity 1110, the cavity wall of the cable cavity 1110 is provided with a locking arm 1120, and the housing 1100 has a plug-in end 1130. The conductor 1200 is passed through the cable cavity 1110, and the conductor 1200 is provided with a limiting groove 1210. The sealing body 1300 is filled between the cavity wall of the cable cavity 1110 and the conductor 1200, and the end of the conductor 1200 close to the plug-in end 1130 is exposed from the sealing body 1300 for electrical connection. Among them, a part of the structure of the locking arm 1120 is inserted into the limiting groove 1210, and the side of the locking arm 1120 facing the plug-in end 1130 abuts against the groove wall of the limiting groove 1210.

[0038] In the above-mentioned plug structure 100, since the sealing body 1300 is filled between the cavity wall of the cable cavity 1110 and the conductor 1200, the sealing body 1300 can cut off and seal the external liquid to improve the waterproofness of the plug structure 100. In addition, the sealing body 1300 is supported between the shell 1100 and the conductor 1200, and the stability of the circumferential position of the conductor 1200 can also be improved. Further, a part of the structure of the locking arm 1120 is inserted into the limiting groove 1210, and the side of the locking arm 1120 facing the plug end 1130 abuts against the groove wall of the limiting groove 1210. Thus, the conductor 1200 can be restricted from moving in the shell 1100 by the locking arm 1120. Therefore, the stability of the position of the conductor 1200 in the shell 1100 can be improved by the mutual cooperation between the sealing body 1300 and the locking arm 1120. Such a configuration enables the plug structure 100 to be suitable for harsh environments such as vibration and humidity.

[0039] 3 and 4, in one embodiment, the housing 1100 may include a mounting end 1140 and the above-mentioned plug end 1130. It is understood that the plug end 1130 of the housing 1100 is used for plugging and mating with another plug structure 100, and the mounting end 1140 is an end away from the other plug structure 100, which can be used for the cable to pass through.

[0040] The sealing body 1300 can be arranged in the area near the mounting end 1140 in the housing 1100 to reduce the liquid from entering the housing 1100 from the side of the mounting end 1140. It is easy to understand that the plug end 1130 can also be provided with a corresponding sealing structure (i.e., the sealing sleeve 1600 mentioned below) to seal the plugging part of the plug structure 100. In this way, the waterproofness of the plug structure 100 can be comprehensively improved.

[0041] Please refer to FIG. 2 again. In one embodiment, the locking arm 1120 is elastic, so the locking arm 1120 can be deformed by force. The plug-in end 1130 of the housing 1100 is provided with an opening 1111 communicating with the cable cavity 1110, and the locking arm 1120 is used to be disengaged from the limiting groove 1210 by external force. Since the opening 1111 is connected with the cable cavity 1110, and the locking arm 1120 is arranged in the cable cavity 1110, the locking arm 1120 can be disengaged from the limiting groove 1210 by inserting a tool into the cable cavity 1110 from the opening 1111 and deforming the locking arm 1120, so as to unlock the conductor 1200. Thus, by unlocking the conductor 1200, the conductor 1200 can be removed from the housing 1100. Furthermore, when the plug structure 100 fails, the conductor 1200 and the housing 1100 can be unsealed to replace the conductor 1200 or the housing 1100 accordingly.

[0042] Please refer to FIG. 2 . In one embodiment, the locking arm 1120 is recessed on the side of the opening 1111 and is provided with a slot 1121. The slot 1121 includes a clamping wall 1122 and a driving wall 1123 arranged opposite to each other. The clamping wall 1122 is located in the limiting groove 1210 and is clamped with the groove wall of the limiting groove 1210. The driving wall 1123 is located outside the limiting groove 1210. The driving wall 1123 is used to drive the clamping wall 1122 to escape from the limiting groove 1210 when subjected to an external force. Since the driving wall 1123 is located outside the limiting groove 1210, as described above, a tool can be inserted into the cable cavity 1110 from the opening 1111 to move the locking arm 1120 as a whole by contacting the driving wall 1123. Thus, the locking arm 1120 can be removed from the limiting groove 1210, and the locking arm 1120 is unlocked from the conductor 1200.

[0043] Furthermore, the locking groove 1121 may be a V-shaped groove or a U-shaped groove, so that the driving wall 1123 located outside the limiting groove 1210 can drive the locking wall 1122 to escape from the limiting groove 1210 .

[0044] Further, as shown in FIG2 , a socket 1124 may be provided on the slot wall of the slot 1121, the socket 1124 faces the opening 1111, and at least a portion of the socket 1124 is located on the driving wall 1123. The socket 1124 is used for inserting a tool so that the tool can move the locking arm 1120. The tool may be a tool with a slender strip-shaped portion, such as a screwdriver.

[0045] Please refer to FIG. 2 and FIG. 3 again. In one embodiment, a bracket 1400 is provided in the cable cavity 1110, and the bracket 1400 is connected to the cavity wall of the cable cavity 1110. The sealing body 1300 includes an enclosure 1310 and a limiting disk 1320. The limiting disk 1320 is connected to the outer periphery of one end of the enclosure 1310 close to the plug end 1130 to abut against the cavity wall of the cable cavity 1110. The plug structure 100 also includes a fixing sleeve 1500. The fixing sleeve 1500 is inserted into the area of ​​the cable cavity 1110 away from the plug end 1130 and is sleeved outside the enclosure 1310, that is, the fixing sleeve 1500 is inserted into the installation end 1140. The fixing sleeve 1500 is clamped with the housing 1100 and presses the limiting disk 1320 against the side of the bracket 1400 away from the plug end 1130. Since the fixing sleeve 1500 is clamped with the housing 1100, the clamping force provided by the housing 1100 enables the fixing sleeve 1500 to firmly press the limiting plate 1320 against the side of the bracket 1400 away from the plug-in end 1130. Thus, the sealing body 1300 can be stably placed in the housing 1100 to improve the sealing performance of the housing 1100. It can be understood that the fixing sleeve 1500 is sleeved outside the enveloping body 1310, that is, at this time, the fixing sleeve 1500 is sandwiched between the housing 1100 and the enveloping body 1310, and this area also has sealing performance.

[0046] Furthermore, the shell 1100 is provided with an installation opening 1112 at the installation end 1140 , and the sealing body 1300 and the fixing sleeve 1500 can be successively installed into the cable cavity 1110 from the installation opening 1112 , and the fixing sleeve 1500 can be pushed to move to a position engaged with the shell 1100 to press against the limiting plate 1320 .

[0047] In one embodiment, the sealing body 1300 can be made of a soft rubber material, such as silicone, rubber, etc. Therefore, the limiting plate 1320 can be deformed to a certain extent under the clamping of the fixing sleeve 1500 and the bracket 1400 to be tightly filled between the conductor 1200 and the cavity wall of the cable cavity 1110. In this way, the sealing performance of the plug structure 100 can be further improved. In addition, the soft rubber material also has a certain shock absorption and buffering ability, so the anti-seismic ability of the electrical connector 10 can be further improved.

[0048] Please refer to FIG. 3 and FIG. 4 . In one embodiment, the fixing sleeve 1500 is detachably engaged with the housing 1100. Since the sealing body 1300 is held in the cable cavity 1110 by the pushing action of the fixing sleeve 1500, after the fixing sleeve 1500 and the housing 1100 are disassembled, the sealing body 1300 can also be removed from the cable cavity 1110. Thus, combined with the detachable nature of the locking arm 1120, each component included in the plug structure 100 is detachable, so that the corresponding component can be replaced when a fault occurs in the plug structure 100, thereby reducing the use cost of the plug structure 100.

[0049] Please refer to FIG. 3 and FIG. 4 , in one embodiment, a clamping block 1510 is provided on the outside of the fixing sleeve 1500, and a clamping hole 1150 is provided on the housing 1100. The clamping block 1510 can be clamped with the clamping hole 1150 to fix the fixing sleeve 1500 relative to the housing 1100. The clamping block 1510 can be a wedge-shaped block, and the housing 1100 has a certain degree of deformability, so that the fixing sleeve 1500 can be smoothly clamped into the clamping hole 1150 when it passes into the housing 1100 from the installation end 1140.

[0050] Please refer to FIG. 4 and FIG. 5. In one embodiment, the cable cavity 1110 includes a sealed cavity 1113 and a threading hole 1114. The sealed cavity 1113 is located on a side of the housing 1100 close to the mounting end 1140, and the threading hole 1114 is located on a side of the housing 1100 close to the plug end 1130. The locking arm 1120 is disposed in the threading hole 1114. The sealed cavity 1113 is connected to the threading hole 1114, and the conductor 1200 can be passed through the threading hole 1114 from the sealed cavity 1113. The threading hole 1114 can be formed in the bracket 1400, and the position of the conductor 1200 is limited by the threading hole 1114, so that the conductors 1200 of the two plugs can be connected and connected when the two plug structures 100 are plugged in. The fixing sleeve 1500 and the sealing body 1300 can be inserted in the sealed cavity 1113 and the threading hole 1114 can be sealed relative to the outside to improve the sealing performance of the plug structure 100.

[0051] As shown in FIG5 , it should be noted that the bracket 1400 includes a positioning surface 1410 that abuts against the limiting plate 1320. The bracket 1400 is not limited to being abruptly disposed in the cable cavity 1110. The bracket 1400 may also be a step-shaped structure formed by a sudden change in the inner cavity size of the cable cavity 1110. In this case, the positioning surface 1410 of the bracket 1400 is used to define the sealing cavity 1113 and the threading hole 1114 as described above in the cable cavity 1110.

[0052] Further, the plug structure 100 may include a plurality of conductors 1200, and the bracket 1400 may further include a plurality of partitions 1420, which are arranged at intervals to cooperate with the inner wall of the cable cavity 1110 to form a plurality of threading holes 1114. A locking arm 1120 is provided in each threading hole 1114 to limit the position of the cables passed through each threading hole 1114.

[0053] Please refer to FIG. 6 and FIG. 7 . An embodiment of the present application further provides an electrical connector 10. The electrical connector 10 includes a plug structure 100 as described in each embodiment. The plug structures 100 are plugged into each other to form an electrical connection. For ease of understanding and explanation, one of the two plug structures 100 is referred to as a male plug 101 and the other is referred to as a female plug 102. The plug end 1130 of the male plug 101 is plugged into the plug end 1130 of the female plug 102 facing each other. It should be understood that the male plug 101 and the female plug 102 are both the plug structures 100 described in each embodiment, so the male plug 101 and the female plug 102 also include all the technical features of the plug structure 100 described in each embodiment and the technical effects that can be obtained according to the technical features.

[0054] In order to facilitate further distinction and understanding, the following will be prefixed with "first" for each feature included in the male plug 101, and the prefixed with "second" for each feature included in the female plug 102. For example, the male plug 101 includes a first shell 1101, a first conductor 1201, and a first wire sealing body 1301. The first shell 1101 is provided with a first cable cavity 1110a, and the cavity wall of the first cable cavity 1110a is provided with a first locking arm 1120a, and the first shell 1101 has a first plug-in end 1131 and a first mounting end 1141 arranged opposite to each other. The first conductor 1201 is inserted into the first cable cavity 1110a, and the first conductor 1201 is provided with a first limiting groove 1211. The first wire sealing body 1301 is filled between the cavity wall of the first cable cavity 1110a and the first conductor 1201, and the end of the first conductor 1201 close to the first plug-in end 1131 is exposed to the first wire sealing body 1301. Part of the structure of the first locking arm 1120a is inserted into the first limiting groove 1211, and the side of the first locking arm 1120a facing the first plug end 1131 abuts against the groove wall of the first limiting groove 1211. Other features are similar and will not be described in detail.

[0055] Similarly, the female plug 102 may include a second shell 1102, a second conductor 1202 and a second wire sealing body 1302. The second shell 1102 is provided with a second cable cavity 1110b, the cavity wall of the second cable cavity 1110b is provided with a second locking arm 1120b, and the second shell 1102 has a second plug-in end 1132 and a second mounting end 1142 arranged opposite to each other.

The second wire sealing body 1302 is filled between the cavity wall of the second cable cavity 1110b and the second conductor 1202, and the end of the second conductor 1202 close to the second plug-in end 1132 is exposed from the second wire sealing body 1302. Part of the second locking arm 1120b is inserted into the second limiting groove 1212, and the side of the second locking arm 1120b facing the second plug end 1132 abuts against the groove wall of the second limiting groove 1212. Other features are similar and will not be described in detail.

[0056] Please refer to FIG. 8 . In one embodiment, at least one of the male plug 101 and the female plug 102 is provided with a sealing sleeve 1600. The second housing 1102 is sleeved outside the first housing 1101, and the sealing sleeve 1600 is sealed and abutted between the outer wall of the first housing 1101 and the inner wall of the second housing 1102. Thus, the sealing sleeve 1600 can improve the sealing performance of the male plug 101 and the female plug 102 at the insertion point. The sealing sleeve 1600, combined with the sealing body 1300 of each of the male plug 101 and the female plug 102, can improve the overall waterproof performance of the electrical connector 10.

[0057] Please refer to FIG. 9 and FIG. 10. In one embodiment, the plug-in end 1130 (i.e., the second plug-in end 1132) of the second housing 1102 extends toward the first housing 1101 along the plug-in direction K to form a hollow sleeve portion 1160. The sleeve portion 1160 is sleeved on the plug-in end 1130 of the first housing 1101 to improve the plug-in stability of the male plug 101 and the female plug 102, and to isolate the joint between the first conductor 1201 and the second conductor 1202 inside the electrical connector 10. The bracket 1400 of the female plug 102 is the second bracket 1402. The female plug 102 further includes a buckle 1700. The buckle 1700 and the sealing sleeve 1600 are inserted into the sleeve portion 1160. The buckle 1700 is engaged with the sleeve portion 1160 to press the sealing sleeve 1600 against the second bracket 1402. Thus, the sealing sleeve 1600 can be fixed on the inner wall of the sleeve portion 1160 by the buckle 1700. When the female plug 102 is plugged into the male plug 101, the buckle 1700 can be sleeved on the plug end 1130 of the first housing 1101, so that the first plug end 1131 and the second plug end 1132 form a sealed fit. It should be noted that the plug-in direction K described in each embodiment is the plug-in direction K of the male plug 101 and the female plug 102.

[0058] It can be understood that the socket part 1160 is formed by extending the second plug-in end 1132 along the plug-in direction K toward the first shell 1101. Therefore, relative to the first shell 1101, the socket part 1160 has a larger installation space and support space to facilitate the buckle 1700 to limit and fix the sealing sleeve 1600 on the socket part 1160.

[0059] Of course, in some embodiments, the sealing sleeve 1600 can also be sleeved on the first plug-in end 1131 of the first shell 1101. Then, when the sleeve portion 1160 is sleeved on the first plug-in end 1131, the sealing sleeve 1600 can abut between the inner wall of the sleeve portion 1160 and the outer wall of the first plug-in end 1131 to improve the waterproofness of the electrical connector 10 after insertion.

[0060] Please continue to refer to FIG. 9 and FIG. 10. In one embodiment, the sleeve portion 1160 is provided with a clamping plate 1161 clamped with the first shell 1101, and the sleeve portion 1160 is further provided with at least two clamping grooves 1162, and the buckle 1700 is clamped with the clamping grooves 1162. At least two clamping grooves 1162 are located on opposite sides of the clamping plate 1161. Such an arrangement can reduce the interference of the buckle 1700 provided on the sleeve portion 1160 with the clamping of the first shell 1101 and the second shell 1102.

[0061] Furthermore, a first plug end 1131 of the first housing 1101 is provided with a card platform 1180 protruding from the outside, and the card platform 1180 is engaged with the card plate 1161 to achieve the plug-in engagement of the first housing 1101 and the second housing 1102. The card platform 1180 can be a wedge-shaped protrusion to facilitate the engagement of the card plate 1161.

[0062] Please continue to refer to FIG. 9 and FIG. 10. In one embodiment, a guide bar 1170 is protruded from the outer wall of the plug end 1130 of the first housing 1101, and the guide bar 1170 extends along the plug-in direction K. The buckle 1700 includes a body 1710 and a buckle body 1720 disposed on the body 1710. The buckle body 1720 is provided with a guide groove 1721 communicating with the inner cavity of the buckle body 1720, and the guide groove 1721 and the guide bar 1170 are slidably matched. It can be understood that the buckle 1700 is inserted into the sleeve portion 1160, and the guide bar 1170 is protruded from the first plug end 1131. When the male plug 101 and the female plug 102 are plugged into each other, the guide groove 1721 and the guide bar 1170 are slidably matched, and the buckle 170 and the sealing sleeve 1600 can be easily slid to the position of being sleeved on the first plug end 1131. In short, the guiding and sliding cooperation between the guide groove 1721 and the guide bar 1170 can improve the convenience of plugging the male plug 101 and the female plug 102 together, and the sealing stability of the sealing sleeve 1600 after the plugging together.

[0063] Furthermore, the engaging groove 1162 has an abutting wall 1163 located on a side close to the first shell 1101, and the abutting wall 1163 is provided with a notch 1164 for the buckle body 1720 to penetrate. The notch 1164 allows the buckle body 1720 to penetrate into the engaging groove 1162, and the buckle body 1720 abuts against the inner surface of the abutting wall 1163. Thus, the abutting wall 1163 can provide a supporting force for the pressing buckle 1700 to press the sealing sleeve 1600 against the second bracket 1402 by abutting against the buckle body 1720. In short, the abutting of the buckle body 1720 by the abutting wall 1163 can stably position the pressing buckle 1700 and the sealing sleeve 1600 in the sleeve connection portion 1160.

[0064] Furthermore, the size of the notch 1164 can be smaller than the size of the buckle body 1720. When the buckle 1700 is installed, the buckle body 1720 squeezes the wall of the notch 1164 to deform and penetrate into the engaging groove 1162. Thus, the abutting wall 1163 can stably provide support for the buckle 1700.

[0065] It should be noted that since both the male plug 101 and the female plug 102 are the plug structure 100, that is to say, the plug structure 100 also includes all the technical features of the male plug 101 and the female plug 102 described in each embodiment.

[0066] For example, the plug end 1130 of the housing 1100 of the plug structure 100 can extend along the plugging direction K to form a hollow sleeve portion 1160. The bracket 1400 of the female plug 102 is a second bracket 1402. The plug structure 100 also includes a buckle 1700 and a sealing sleeve 1600. The buckle 1700 and the sealing sleeve 1600 are inserted into the sleeve portion 1160. The buckle 1700 is engaged with the sleeve portion 1160 to press the sealing sleeve 1600 against the bracket 1400. The other features are similar, so they are not repeated here.

[0067] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
