[0057] In order to make the technical problems, technical solutions and beneficial effects solved by the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0058] As shown in the drawings, Figures 1 to 11 An embodiment of the present application provides a sheath 1, which comprises a sheath body 11, a sealing ring 12 and a position guaranteeing member 13. The sealing ring 12 is annular, and the sealing ring 12 is sleeved on the outside of the sheath body 11. The central axis of the sealing ring 12 coincides with the central axis of the sheath body 11. The sheath body 11 is provided with a plug-in cavity 111, which extends along a direction perpendicular to the central axis of the sheath body 11.

[0059] The position guaranteeing member 13 comprises a guaranteeing member body 131 and a limiting member connected to the guaranteeing member body 131. The guaranteeing member body 131 is plug-in fitted in the plug-in cavity 111. The shape of the guaranteeing member body 131 is adapted to the shape of the plug-in cavity 111. The guaranteeing member body 131 is provided with a plurality of terminal insertion holes 1311. The terminals 41 of the connector 100 can pass through the terminal insertion holes 1311. The position guaranteeing member 13 can secondarily fix the terminals 41, thereby increasing the holding force of the terminals 41.

[0060] The limiting member is arranged around the outer edge of the guaranteeing member body 131. The limiting member is located outside the plug-in cavity 111 and abuts against the sealing ring 12, thereby limiting the sealing ring 12. Wherein, the relative position of the limiting member and the guaranteeing member body 131 is indicated by surrounding. At least part of the inner edge of the limiting member is connected to the outer edge of the guaranteeing member body 131.

[0061] The sheath 1 provided by the embodiment of the present application can protect the guaranteeing member body 131. During the plug-in and pull-out of the male and female sheaths 1, the guaranteeing member body 131 will not contact the position guaranteeing member 13. The guaranteeing member body 131 is not easily deformed or damaged due to force. During the plug-in and pull-out of the male and female sheaths, the position guaranteeing member 13 is not easily loosened or separated from the plug-in cavity 111.

[0062] Moreover, since the limiting member is arranged around the guaranteeing member body 131, the limiting member can resist and limit the sealing ring 12 around, thereby preventing the sealing ring 12 from moving in the axial direction of the sheath body 11. When the male and female sheaths 1 are plugged in and pulled out, the sealing ring 12 is not loosened due to force, and has high reliability. When the sealing ring 12 is limited by the limiting member, the sealing ring 12 is not subjected to force and is not compressed. When the male and female sheaths 1 are plug-in fitted, the sealing ring 12 is compressed, thereby achieving sealing.

[0063] In an embodiment, as shown in the drawings, Figure 3 , Figure 4As shown, the limiting members include a first limiting member 132 and a second limiting member 133, which are oppositely arranged on the guarantee member body 131, one of the first limiting member 132 and the second limiting member 133 is arranged around at least part of the edge of the guarantee member body 131, and the other is arranged around the remaining edge of the guarantee member body 131, which together form a surrounding of the guarantee member body 131 and resist and limit the four sides of the sealing ring 12.

[0064] For the convenience of describing the structure of the sheath body 11, the central axis of the sheath body 11 is defined as the front-rear direction, the plug-in end of the sheath body 11 is the front, and the wire end of the sheath body 11 is the rear. The plug-in direction of the position guarantee member 13 is defined as the vertical direction, that is, the thickness direction of the sheath body 11 is the vertical direction, and the width direction of the position guarantee member 13 is the horizontal direction. The meanings of "front-rear direction", "vertical direction" and "horizontal direction" in the following embodiments are the same as in this embodiment, and will not be described again.

[0065] In an embodiment, as shown in Figure 6 The sheath body 11 includes a stop portion 112, and the guarantee member body 131 abuts against the stop portion 112. The stop portion 112 is located at the bottom of the plug-in cavity 111, the plug-in cavity 111 is an open cavity, the guarantee member body 131 moves downward from the opening of the plug-in cavity 111 until it stops moving when it abuts against the stop portion 112, at this time, the first limiting member 132 and the second limiting member 133 are both located outside the plug-in cavity 111. The stop portion 112 can stop the position guarantee member 13 and limit its plug-in position on the sheath body 11.

[0066] The stop portion 112 is provided with a through hole 1121 communicating with the plug-in cavity 111, the first limiting member 132 is arranged on the side of the guarantee member body 131 close to the stop portion 112, when the guarantee member body 131 abuts against the stop portion 112, the first limiting member 132 extends out of the plug-in cavity 111 from the through hole 1121 and abuts against the sealing ring 12, the second limiting member 133 is arranged on the side of the guarantee member body 131 away from the stop portion 112, and the second limiting member 133 cannot enter the plug-in cavity 111 and remains outside the plug-in cavity 111.

[0067] The first limiting member 132 is connected below the guarantee member body 131 and can limit the lower part of the sealing ring 12, the second limiting member 133 can limit the upper part, left side and right side of the sealing ring 12, and the first limiting member 132 and the second limiting member 133 together surround the guarantee member body 131 to abut and limit the four sides of the sealing ring 12.

[0068] In an embodiment, as shown in Figure 4As shown, the first limiting member 132 comprises at least one protruding block 1321 which is extended from the guarantee member body 131 towards the stop portion 112, when the guarantee member body 131 abuts against the stop portion 112, the protruding block 1321 passes through the through hole 1121 and extends out of the insertion cavity 111.

[0069] It should be noted that the protruding block 1321 can be square or strip-shaped, and the shape of the through hole 1121 is determined according to the shape of the protruding block 1321. When the protruding block 1321 is square, a plurality of protruding blocks 1321 can be provided and arranged along the transverse direction of the guarantee member body 131, and the number of the through holes 1121 should be consistent with the number of the protruding blocks 1321, and each protruding block 1321 passes through the corresponding through hole 1121 to ensure the limiting effect on the lower part of the sealing ring 12.

[0070] The protruding block 1321 can also be strip-shaped, and at this time, the number of the protruding block 1321 can be one, and the through hole 1121 is also strip-shaped.

[0071] In an embodiment, as shown in the drawings, Figure 4 The second limiting member 133 comprises a connecting member 1331, a first extending member 1332 and a second extending member 1333, the connecting member 1331 is installed on the side of the guarantee member body 131 away from the stop portion 112, the first extending member 1332 and the second extending member 1333 are respectively connected to the two ends of the connecting member 1331, and the first extending member 1332 is extended from one end of the connecting member 1331 towards the stop portion 112, and the second extending member 1333 is extended from the other end of the connecting member 1331 towards the stop portion 112, the second limiting member 133 is arranged along the upper, left and right edges of the guarantee member body 131, and the connecting member 1331, the first extending member 1332, the second extending member 1333 and the first limiting member 132 are arranged around the guarantee member body 131, which can stop and limit the sealing ring 12 in four directions respectively, preventing the sealing ring 12 from moving in the axial direction.

[0072] Preferably, the first extending member 1332 and the second extending member 1333 are symmetrically arranged on the two sides of the connecting member 1331.

[0073] In a preferred embodiment, as shown in the drawings, Figure 4 The first extending member 1332 and the second extending member 1333 each comprise a straight segment and an arc segment, the arc segment is connected between one end of the straight segment and the connecting member 1331, and the other end of the straight segment is a free end, the smooth connection between the straight segment and the connecting member 1331 is realized through the arc segment, and the overall shape of the first extending member 1332 and the second extending member 1333 is substantially the same as the shape of the part on the left and right sides of the sealing ring 12, so that the second limiting member 133 and the sealing ring 12 have more contact area and have better limiting effect.

[0074] The connecting piece 1331 can be in a strip shape, and the first extending piece 1332 and the second extending piece 1333 are respectively connected to two ends of the connecting piece 1331. At this time, the connecting piece 1331 is in a U shape. Alternatively, the connecting piece 1331 can also be a plurality of blocks arranged at intervals, the first extending piece 1332 is connected to one block at the leftmost side of the guarantee piece body 131, and the second extending piece 1333 is connected to one block at the rightmost side of the guarantee piece body 131.

[0075] In an embodiment, as shown in Figure 4 , the first extending piece 1332 and the guarantee piece body 131 have a first gap 134, and the second extending piece 1333 and the guarantee piece body 131 have a second gap 135. When the position guarantee piece 13 is matched with the sheath body 11, the guarantee piece body 131 is inserted into the insertion cavity 111, and the first extending piece 1332 and the second extending piece 1333 do not enter the insertion cavity 111, so as to abut and limit the sealing ring 12 arranged outside the sheath body 11.

[0076] In an embodiment, as shown in Figure 5 , Figure 6 , the sheath body 11 further includes a first body part 113, a second body part 114, a first connecting part 115 and a second connecting part 116. The first body part 113, the second body part 114, the first connecting part 115 and the second connecting part 116 are arranged around the stop part 112. The first body part 113 and the second body part 114 are oppositely arranged. The first connecting part 115 and the second connecting part 116 are oppositely arranged and connected between the first body part 113 and the second body part 114. The insertion cavity 111 is formed between the first body part 113, the second body part 114, the first connecting part 115, the second connecting part 116 and the stop part 112, so that the insertion cavity 111 is a cylindrical cavity with one end open.

[0077] As shown in Figure 2 , when the guarantee piece body 131 is inserted into the insertion cavity 111, the first connecting part 115 is inserted and matched in the first gap 134, and the second connecting part 116 is inserted and matched in the second gap 135, so as to realize the connection between the position guarantee piece 13 and the sheath body 11, and the limiting of the sealing ring 12 by the second limiting piece 133. Furthermore, when the top of the first connecting part 115 abuts against the arc-shaped section of the first extending piece 1332, and the top of the second connecting part 116 abuts against the arc-shaped section of the second extending piece 1333, the insertion depth of the position guarantee piece 13 in the insertion cavity 111 is limited to a certain extent.

[0078] In an embodiment, as shown in Figure 3 , Figure 8 , Figure 11As shown, the first body part 113 is provided with a plurality of first plug-in holes 1131, and the second body part 114 is provided with a plurality of second plug-in holes 1141, the plurality of first plug-in holes 1131 and the plurality of second plug-in holes 1141 are arranged one by one, and the number of the first plug-in holes 1131, the number of the terminal plug-in holes 1311 and the number of the second plug-in holes 1141 are consistent. The position assurance part 13 has a pre-assembly position and a locking position, when the position assurance part 13 is in the pre-assembly position, the first plug-in hole 1131 is aligned with the corresponding terminal plug-in hole 1311 and the corresponding second plug-in hole 1141 to form a plug-in channel of the terminal 41. When the position assurance part 13 is in the locking position, the first plug-in hole 1131 and the second plug-in hole 1141 are aligned, the terminal plug-in hole 1311 is misaligned with the first plug-in hole 1131, and the terminal plug-in hole 1311 is misaligned with the second plug-in hole 1141.

[0079] Specifically, as shown in Figure 7 、 Figure 8 When the position assurance part 13 is matched with the sheath body 11, the assurance part body 131 is aligned with the opening of the plug-in cavity 111, the first connecting part 115 is aligned with the first gap 134, and the second connecting part 116 is aligned with the second gap 135, and then the assurance part body 131 is moved downward in the plug-in cavity 111 to the pre-assembly position, and the first plug-in hole 1131, the terminal plug-in hole 1311 and the second plug-in hole 1141 form a plug-in channel, and a plurality of terminals 41 are inserted one by one in each plug-in channel.

[0080] As shown in Figure 9 、 Figure 11 Continuing to move the position assurance part 13, when the assurance part body 131 moves from the pre-assembly position to the locking position, the terminal plug-in hole 1311 continues to move downward, and the first plug-in hole 1131 and the second plug-in hole 1141 remain aligned, thereby forming the misalignment of the terminal plug-in hole 1311 with the corresponding first plug-in hole 1131 and the corresponding second plug-in hole 1141. At this time, the inner wall of the terminal plug-in hole 1311 can abut against the terminal 41, and the terminal 41 cannot be pulled out of the plug-in channel, thereby achieving secondary fixation of the terminal 41 and providing higher terminal 41 retention force.

[0081] In an embodiment, the area occupied by the plurality of first plug-in holes 1131 is not centrally arranged on the first connecting part 115, forming an asymmetric structure of the terminal 41, which can avoid incorrect insertion direction during insertion and removal of the male and female sheaths 1. The position assurance part 13 does not need to be provided with a mistake-proof structure of the sheath 1, so that the male and female sheaths 1 will not contact the position assurance part 13 during insertion and removal, thereby effectively protecting the position assurance part 13 and reducing costs.

[0082] In an embodiment, as shown in Figure 4 、 Figure 6As shown, the sheath body 11 is provided with an error prevention piece 117, which is arranged in the insertion cavity 111 and extends along the depth direction of the insertion cavity 111. The guarantee piece body 131 is provided with an error prevention notch 1312, and the error prevention piece 117 is arranged in the error prevention notch 1312. Through the cooperation of the error prevention piece 117 and the error prevention notch 1312, the insertion direction of the guarantee piece body 131 can be limited, and the correct insertion of the guarantee piece body 131 and the insertion cavity 111 can be ensured. Preferably, the error prevention piece 117 is arranged at the joint of the first body part 113 and the first connecting part 115.

[0083] In an embodiment, the guarantee piece body 131 is provided with a plurality of buckles, and the sheath body 11 is provided with a plurality of first clamping grooves 1111 and a plurality of second clamping grooves 1112, which are all in communication with the insertion cavity 111. When the position guarantee piece 13 is in the pre-assembly position, the buckle is clamped in the first clamping groove 1111, and when the position guarantee piece 13 is in the locking position, the buckle is clamped in the second clamping groove 1112. Through the cooperation of the buckle and the clamping groove in different positions, the pre-assembly and locking effects can be achieved. Wherein, "a plurality of" refers to two or more.

[0084] In an embodiment, as shown in Figure 4 、 Figure 7 、 Figure 9 The buckle includes a first buckle 136 and a second buckle 137. The first clamping groove 1111 is farther away from the opening of the insertion cavity 111 than the second clamping groove 1112, and the first buckle 136 is farther away from the opening of the insertion cavity 111 than the second buckle 137. When the position guarantee piece 13 is in the pre-assembly position, the first buckle 136 is clamped in the first clamping groove 1111, and at the same time, the second buckle 137 abuts against the inner wall of the insertion cavity 111, so that the position guarantee piece 13 remains in the pre-assembly position and is not easy to move.

[0085] When the position guarantee piece 13 is switched from the pre-assembly position to the locking position, the first buckle 136 moves along the first clamping groove 1111 towards the direction of the stop part 112, and the second buckle 137 is clamped in the second clamping groove 1112 to lock the guarantee piece body 131. At the same time, the guarantee piece body 131 abuts against the stop part 112 to stop the guarantee piece body 131, ensuring that the position guarantee piece 13 is inserted in place.

[0086] In the vertical direction, the length of the first clamping groove 1111 should be greater than the distance that the guarantee piece body 131 moves from the pre-assembly position to the locking position, so that the first buckle 136 can move in the first clamping groove 1111 without interference during the process of the second buckle 137 entering the second clamping groove 1112.

[0087] In an embodiment, as shown in Figure 4As shown, the buckle is provided with four, one first buckle 136 and one second buckle 137 are arranged on the left and right sides of the guarantee element body 131, two first buckles 136 are symmetrically arranged on the guarantee element body 131, and two second buckles 137 are symmetrically arranged on the guarantee element body 131.

[0088] In another embodiment, the buckle is also provided with two, one on the left and right sides of the guarantee element body 131, in this case, the first buckle groove 1111 is closer to the opening of the plug-in cavity 111 than the second buckle groove 1112, the buckle is first buckled in the first buckle groove 1111, and the guarantee element body 131 is continuously moved in the plug-in cavity 111, so that the buckle is separated from the first buckle groove 1111 and buckled in the second buckle groove 1112, realizing preloading and locking. At this time, the distance between the first buckle groove 1111 and the second buckle groove 1112 should be consistent with the distance between the preloading position and the locking position, and the size of the first buckle groove 1111 and the second buckle groove 1112 should be matched with the buckle, so as to realize locking and prevent the position guarantee element 13 from shaking in the vertical direction.

[0089] In an embodiment, as shown in Figure 7 , Figure 9 , Figure 10 As shown, the inner wall of the plug-in cavity 111 is also provided with a plurality of first hooks 118 and a plurality of second hooks 119, the number of first hooks 118 is consistent with the number of first buckles 136, and the number of second hooks 119 is consistent with the number of second buckles 137. The first hook 118 is used to stop the first buckle 136 from separating from the first buckle groove 1111, and the second hook 119 is used to abut the second buckle 137 at the preloading position and stop the second buckle 137 from separating from the second buckle groove 1112 at the locking position.

[0090] Specifically, when the guarantee element body 131 moves to the preloading position, the first buckle 136 is buckled into the first buckle groove 1111, the first hook 118 abuts above the first buckle 136, preventing the guarantee element body 131 from moving towards the opening of the plug-in cavity 111, at this time, the second hook 119 abuts below the second buckle 137, blocking the guarantee element body 131 from continuing to move downward, the first hook 118 and the second hook 119 keep the guarantee element body 131 stationary at the preloading position, so that the terminal 41 can be smoothly plugged through the first plug-in hole 1131, the terminal plug hole 1311 and the second plug-in hole 1141.

[0091] When the guarantee element body 131 moves from the preloading position to the locking position, an external force is applied, and through the deformation of the guarantee element body 131, the second buckle 137 can pass over the second hook 119 and enter the second buckle groove 1112, thereby forming the buckling of the second buckle 137 and the second buckle groove 1112.

[0092] In an embodiment, as shown in Figure 10 The first hook 118 has a first plane 1181 and a first inclined plane 1182, the first inclined plane 1182 is connected with the first plane 1181 at an acute angle, and the first inclined plane 1182 is inclined from one end of the first plane 1181 to a direction away from the insertion cavity 111. The first clasp 136 can abut on the first inclined plane 1182, and under the guidance of the first inclined plane 1182, the guarantee element body 131 can be deformed, so that the first clasp 136 can pass the first hook 118 and enter the first clamping groove 1111.

[0093] The second hook 119 has a second plane 1191 and a second inclined plane 1192, the second plane 1191 is arranged parallel to the first plane 1181, the second plane 1191 is aligned with the end of the first inclined plane 1182 away from the first plane 1181, and the second plane 1191 is farther away from the guarantee element body 131 than the first plane 1181. Therefore, when the first clasp 136 moves towards the first hook 118, the first clasp 136 can be avoided, so that the second hook 119 does not interfere with the first clasp 136, until the first clasp 136 abuts on the first inclined plane 1182, and under the guidance of the first inclined plane 1182, the first clasp 136 can enter the first clamping groove 1111.

[0094] The second inclined plane 1192 is connected with the second plane 1191 at an acute angle, and the second inclined plane 1192 is inclined from one end of the second plane 1191 to a direction away from the insertion cavity 111. When the guarantee element body 131 is in the pre-assembly position, the first clasp 136 is clamped in the first clamping groove 1111, and the second inclined plane 1192 abuts on the second clasp 137, which can block the guarantee element body 131 from moving towards the stop portion 112, so that the position guarantee element 13 stays in the pre-assembly position, facilitating the assembly of the terminal 41. After the terminal 41 is assembled, an external force is applied, and under the guidance of the second inclined plane 1192, the second clasp 137 enters the second clamping groove 1112, so that the guarantee element body 131 moves to the locking position, achieving locking.

[0095] In an embodiment, as shown in Figure 4 The guarantee element body 131 is provided with a boss 138, and the second clasp 137 is arranged on the boss 138, so that when the first clasp 136 enters the first clamping groove 1111, the second clasp 137 can abut on the second inclined plane 1192. In the transverse direction, the distance between the first plane 1181 and the second plane 1191 is consistent with the thickness of the boss 138.
