[0050] As shown in Figures 1 and 2, in the first aspect, the present disclosure provides a wire passing connection assembly, including a wire passing seat 1 and a limiting member 2; the wire passing seat 1 is provided with limiting grooves 11 and stop portions 12 distributed in sequence, and a clamping portion is formed by a protrusion or recess on the limiting member 2, and a clamping fitting portion adapted to the clamping portion is provided on the wire passing seat 1; the wire passing seat 1 is used to be passed through the wire passing hole 31, and when the wire passing seat 1 is passed through the wire passing hole 31, the limiting member 2 is inserted into the limiting groove 11, and the limiting member 2 and the stop portion 12 are respectively abutted against the edge of the wire passing hole 31 at both ends of the wire passing hole 31, and the clamping portion is clamped with the clamping fitting portion.

[0051] The cable holder 1 is used to connect to the cable 5, for example, integrally connected to the cable 5, or detachably connected, which is not a limitation. When the stopper 2 is formed with a protruding snap-fit ​​portion, the snap-fit ​​portion includes a protruding portion for correspondingly snapping with the snap-fitting portion, and the protruding portion protrudes relative to the surrounding area of ​​the protruding portion of the stopper 2. When the stopper 2 is formed with a recessed snap-fit ​​portion, the snap-fit ​​portion includes a recessed portion for correspondingly snapping with the snap-fitting portion, and the recessed portion is recessed relative to the surrounding area of ​​the recessed portion of the stopper 2.

[0052] In this specification, unless otherwise specified, the present disclosure is described with the wire-passing connection assembly being located at the wire-passing hole 31 and in an assembled state. At this time, the limiting groove 11 and the stop portion 12 are sequentially distributed along a first direction, which is the X-axis direction in Figures 1 and 2, that is, the front-to-back direction, wherein the limiting groove 11 is located in front of the stop portion 12, and the limiting groove 11 includes a first groove wall 111 away from the stop portion 12, a second groove wall 112 adjacent to the first groove wall 111, and a third groove wall 113 opposite to the first groove wall 111, wherein the first groove wall 111 is the front groove wall of the limiting groove 11, the third groove wall 113 is the rear groove wall of the limiting groove 11, and the second groove wall 112 is the transition groove wall located between the first groove wall 111 and the second groove wall 112.

[0053] In this embodiment, when the wire seat 1 is passed through the wire hole 31 of the shell 3, for example, the end of the wire seat 1 away from the stop portion 12 passes through the wire hole 31 from back to front (that is, along the X-axis direction shown in Figures 1 and 2), when the first groove wall 111 of the limiting groove 11 away from the stop portion 12 is located at the front end of the wire hole 31, and the stop portion 12 is located at the rear end of the wire hole 31, wherein the front end and the rear end can refer to the front and rear positions of the wire hole 31 along the X-axis direction in Figures 1 and 2, the positive direction of the X-axis (that is, the X-axis The positive direction of the arrow on the X-axis represents the front side, and the negative direction of the X-axis represents the rear side. When the limit member 2 is inserted into the limit slot 11 from top to bottom (that is, along the Z-axis direction, where the positive direction of the Z-axis (that is, the direction of the arrow on the Z-axis) represents the top, and the negative direction of the Z-axis represents the bottom), the limit member 2 abuts against the first slot wall 111 and the front end edge of the wire passing hole 31 respectively, and the stop portion 12 abuts against the rear end edge of the wire passing hole 31, thereby limiting the movement of the wire passing seat 1 and the cable 5 connected thereto along the front and rear direction (that is, the X-axis direction shown in Figures 1 and 2). At the same time, a snap-fitting portion is formed on the limit member 2 in a protruding or recessed manner, and a snap-fitting portion adapted to the snap-fitting portion is provided on the wire-passing seat 1. The snap-fitting portion and the snap-fitting portion are relatively stable. The snap-fitting connection between the snap-fitting portion and the snap-fitting portion can prevent the limit member 2 from being separated from the limit groove 11, specifically, from being separated from the limit groove 11 in the up and down directions, thereby ensuring the position reliability of the limit member 2 when inserted into the limit groove 11, thereby ensuring the position reliability of the limit member 2 abutting against the first groove wall 111 and the front end edge of the wire-passing hole 31, respectively. The wire-passing connection assembly disclosed in the present invention occupies a small space, has high connection reliability, and is easy to assemble.

[0054] As shown in FIG2 , optionally, the limiting groove 11 is formed on the side wall of the wire passing seat 1 opposite to each other along the second direction, the second direction being perpendicular to the first direction, and the first direction being the direction in which the limiting groove 11 and the stop portion 12 are sequentially distributed; the limiting member 2 is generally U-shaped, and the U-shaped structure includes lateral arms 21 arranged opposite to each other and intermediate arms 22 respectively connected to the lateral arms 21; a clamping portion is provided on the intermediate arm 22 and / or the lateral arm 21, for example, the clamping portion can be selectively provided on one of the two lateral arms 21, or can be provided on both the lateral arms 21; for another example, the clamping portion is provided on the intermediate wall 22; for another example, the clamping portion is provided on both the intermediate wall 22 and the lateral arm 21. The design of the clamping portion on the two lateral arms 21 makes the clamping force more symmetrical and the stability better, and the simultaneous arrangement of the clamping portions on the intermediate arm 22 and the lateral arm 21 can improve the reliability of the clamping. The specific arrangement can be selected and configured according to the specific application scenario, and no further specific limitation is made here.

[0055] In this specification, the content of the present disclosure is subsequently explained by taking the example of the limit member 2 being inserted into the limit groove 11 from top to bottom and the second direction being consistent with the left-right direction. However, it should be understood that when there is sufficient space around the wire hole 31, it is not limited to this. For example, the second direction can also be consistent with the up-down direction. In this case, the limit groove 11 extends along the left-right direction.

[0056] The form of the clamping portion provided on the middle arm 22 or the lateral arm 21 is not limited and will be exemplified later.

[0057] In this way, the two lateral arms 21 of the limit member 2 are respectively aligned with the limit slots 11 on the left and right sides of the wire passing seat 1, and the limit member 2 is moved from top to bottom so that the lateral arms 21 are inserted into the limit slots 11 until the limit member 2 moves to the clamping portion and the clamping matching portion to clamp, and the limit member 2 is inserted into place. At this time, the clamping portion and the clamping matching portion can at least limit the upward movement of the limit member 2, and the downward movement of the limit member 2 can be limited by the side wall of the wire passing seat 1 close to the middle arm 22, so that the limit member 2 and the wire passing seat 1 maintain a reliable connection.

[0058] The number of the snap-fitting parts can be set to one or more, and correspondingly, the number of the snap-fitting parts can be one or more.

[0059] As shown in Figures 1 and 2, optionally, the clamping portion includes a first clamping portion, the first clamping portion is formed on the inner wall surface 211 of the lateral arm 21, and the clamping fitting portion includes a first clamping fitting portion formed in the limiting groove 11 and located on the second groove wall 112, and the first clamping portion and the first clamping fitting portion are respectively the first clamping groove 23 and the first clamping protrusion 13.

[0060] Figures 1 and 2 illustrate a case where the first engaging portion is a first engaging groove 23 and the first engaging engagement portion is a first engaging protrusion 13. It should be understood that the first engaging portion may also be a first engaging protrusion 13 and the first engaging engagement portion may be a first engaging groove 23. This specification primarily uses the former as an example.

[0061] At this time, the first clamping portion should be spaced apart from the middle arm 22, and should also be spaced apart from the end of the lateral arm 21. Figures 1 and 2 show the situation where the first clamping portion is located in the middle position of the lateral arm 21 along the up and down directions. Figures 7, 8, 10, 11 and 12 show the situation where the first clamping portion is located in the lower half of the lateral arm 21, that is, the first clamping portion is located between the middle position and the lower end face of the lateral arm 21. It is set as needed.

[0062] In this way, when the limit member 2 is inserted into the limit groove 11 from top to bottom, the lateral arm 21 expands outward along the left and right directions due to the abutment of the first clamping protrusion 13 in the left and right directions until the first clamping protrusion 13 is accommodated in the first clamping groove 23 and then moves inward along the left and right directions, and is restricted from escaping from the limit groove 11 by the abutment of the first clamping protrusion 13 and the first clamping groove 23 in the up and down directions.

[0063] As shown in Figures 14 to 16, optionally, the clamping portion includes a second clamping portion, the second clamping portion includes a second clamping protrusion 24, the second clamping protrusion 24 is arranged at the end of the lateral arm 21 away from the middle arm 22 and is located on the inner wall surface 211 of the lateral arm 21, the clamping fitting portion includes a second clamping fitting portion 14 arranged corresponding to the second clamping portion, and the limiting groove 11 forms a second clamping fitting portion 14 on the end face at the end away from the middle arm 22.

[0064] Specifically, at this time, the portion of the lower end surface of the limiting groove 11 adjacent to the second groove wall 112 forms the second snap-fitting portion 14, and the transition connection between the lower end surface of the limiting groove 11 and the second groove wall 112 can have a certain curvature, so that the second snap-fitting protrusion 24 can be smoothly snapped into the second snap-fitting portion 14.

[0065] In this case, the structure of the second snap-fitting portion 14 is relatively simple. When the second snap-fitting protrusion 24 is snapped into engagement with the second snap-fitting portion 14, the lateral arm 21 is reset inwardly along the left and right directions. Force needs to be applied to move the lateral arm 21 outwardly along the left and right directions so that the second snap-fitting protrusion 24 is disengaged from the second snap-fitting portion 14 before the engagement between the two can be released.

[0066] As shown in Figures 3, 4 and 6, optionally, the clamping portion includes a third clamping portion 25, the third clamping portion 25 includes a connecting arm 251 and a third clamping protrusion 252, a receiving space 27 is provided on the limiting member 2, one end of the connecting arm 251 is fixed in the receiving space 27, the third clamping protrusion 252 is formed at the end of the connecting arm 251 and is at least partially exposed in the receiving space 27, and the clamping fitting portion includes a third clamping fitting portion 15 arranged corresponding to the third clamping protrusion 252.

[0067] Specifically, when the limiting member 2 is inserted into the limiting groove 11 from top to bottom, the third clamping fitting portion 15 is located on the movement path of the third clamping protrusion 252 .

[0068] In this way, the accommodating space 27 is used to provide a swinging space for the connecting arm 251. When the third clamping protrusion 252 moves in a direction perpendicular to the up and down direction, the movement displacement requirement of the third clamping protrusion 252 is adapted by the swinging of the end of the connecting arm 251, which can reduce the deformation requirement of the main part of the limit member 2, such as the main part of the middle arm 22 and the lateral arm 21, thereby facilitating the insertion and removal of the limit member 2, with a simple structure and strong practicality.

[0069] As shown in FIG. 3 , optionally, the connecting arm 251 is extended along the direction in which the limiting member 2 is inserted into the limiting groove 11 , and the end of the connecting arm 251 is disposed away from the middle arm 22 .

[0070] At this time, the connecting arm 251 is generally extended in the up-down direction, but it should be understood that the connecting arm 251 can have a smaller angle with the up-down direction, such as an angle of 0-5°, which will not be described in detail here.

[0071] This arrangement allows the vertical dimension of the stopper 2 to be utilized to arrange the connecting arm 251. The connecting arm 251 can be set to a longer length as needed, thereby ensuring that the third engaging protrusion 252 can be displaced perpendicularly to the vertical direction during the engaging process by swinging the end of the connecting arm 251. This arrangement has a simple structure and strong practicality. This example will be used to illustrate the present disclosure.

[0072] As shown in FIG3 , optionally, the middle arm 22 is provided with a third clamping portion 25 , and a third clamping fitting portion 15 corresponding to the third clamping portion 25 on the middle arm 22 is provided on the side wall of the wire passing seat 1 facing the middle arm 22 .

[0073] This arrangement can utilize the space on the side wall of the wire passing seat 1 facing the middle arm 22 to arrange the third snap-fitting portion, which has a more compact structure and occupies less space.

[0074] Furthermore, the third engaging portion 15 includes an insertion hole 151 and a first limiting portion. The insertion hole 151 is provided on the side wall of the wire guide seat 1 facing the intermediate arm 22 (i.e., provided on the upper side wall in the figure). The first limiting portion is a second engaging groove 152 or a limiting protrusion provided on the inner wall of the insertion hole 151. The connecting arm 251 is inserted into the insertion hole 151, and the third engaging protrusion 252 is engaged with the first limiting portion. FIG3 shows a case where the first limiting portion is the second engaging groove 152, and the second engaging groove 152 extends forward through the limiting member 2.

[0075] In this way, when the third clamping protrusion 252 enters the socket 151 from top to bottom and enters the second clamping groove 152, the third clamping protrusion 252 abuts against the upper side wall of the second clamping groove 152, thereby realizing the clamping connection between the third clamping part 25 and the third clamping matching part 15, limiting the limit member 2 from separating upward from the wire seat 1. At this time, the connecting arm 251 can also work together with the socket 151 to limit the rotation of the limit member 2 relative to the wire seat 1.

[0076] As shown in Figures 4 and 6, optionally, a third clamping portion 25 is provided on the lateral arm 21; when the third clamping portion 25 is provided on the lateral arm 21, the third clamping fitting portion 15 corresponding to the third clamping portion 25 on the lateral arm 21 includes a third clamping groove 153 formed on the groove wall of the limiting groove 11.

[0077] At this time, the third engaging groove 153 formed on the groove wall of the limiting groove 11 is engaged with the third engaging protrusion 252 of the third engaging portion 25, thereby improving the structural compactness of the wire passing seat 1.

[0078] Furthermore, the third clamping protrusion 252 of the third clamping portion 25 on the lateral arm 21 is protruding from the first wall surface 212 of the lateral arm 21 close to the first groove wall 111 , and the third clamping groove 153 is provided on the first groove wall 111 .

[0079] Of course, in another embodiment, the third engaging protrusion 252 of the third engaging portion 25 on the lateral arm 21 may be provided protruding from the inner wall surface 211 of the lateral arm 21, and the third engaging groove 153 may be provided on the second groove wall 112 of the limiting groove 11 adjacent to the first groove wall 111. This description takes the former as an example.

[0080] At this time, the accommodating space 27 on the lateral arm 21 is a notch set close to the inner wall surface 211, and the connecting arm 251 and the lateral arm 21 are spaced apart from the second wall surface away from the first wall surface 212 in the front-to-back direction, so that the end of the connecting arm 251 can swing left and right to a certain extent, thereby meeting the displacement space requirement during the process of engaging and releasing the third engaging protrusion 252.

[0081] In this way, the third engaging groove 153 is provided by utilizing the first groove wall 111 or the second groove wall 112 of the limiting groove 11 , which has a simple structure, is easy to manufacture, and has a low production cost.

[0082] In the above embodiment, the clamping portion may include one or more of the first clamping portion, the second clamping portion, and the third clamping portion 25. When the clamping portion includes multiple types, the positional arrangement of the multiple types should be considered to avoid mutual interference.

[0083] As shown in Figures 4 and 5, optionally, the first wall surface 212 of the limiting member 2 arranged close to the first groove wall 111 and the part in contact with the first groove wall 111 are set as a slope, and along the direction in which the limiting member 2 is inserted into the limiting groove 11, the distance from the point on the slope to the stop portion 12 gradually decreases.

[0084] As shown in Figure 5, it shows the case where the first wall 212 is an entire inclined surface. At this time, the second wall on the limit member 2 away from the first wall 212 in the front-to-back direction can be set to be parallel to the YZ plane, that is, from top to bottom, the thickness of the lateral arm 21 in the front-to-back direction gradually decreases.

[0085] In this way, it is convenient to insert the limit member 2 into the limit groove 11, or take it out from the limit groove 11. Taking the process of inserting the limit member 2 into the limit groove 11 as an example, in the process of inserting the limit member 2 into the limit groove 11 from top to bottom, since the contact part of the first wall 212 and the first groove wall 111 is set as a slope, the two contact through the slope. During the insertion of the limit member 2, the insertion movement of the limit member 2 from top to bottom will be converted into the axial backward movement of the limit member 2, so that the limit member 2 abuts against the front end edge of the wire hole 31, or it is converted into the movement of the wire seat 1 from back to front, so that the stop part 12 abuts against the rear end edge of the wire hole 31, which has high reliability and strong practicality.

[0086] As shown in Figures 8 to 13, different from the above-mentioned case where the first wall surface 212 is an overall inclined surface, optionally, the first groove wall 111 is perpendicular to the direction in which the limiting groove 11 and the stop portion 12 are distributed in sequence, and a weight-reducing structure 28 is provided at one end or both ends of the limiting member 2 along the direction in which the limiting groove 11 and the stop portion 12 are distributed in sequence.

[0087] Specifically, in the figures, the first slot wall 111 and the third slot wall 113 are parallel to the YZ plane. Weight-reducing structures 28 can be provided at both the front and rear ends of the lateral arm 21. The specific arrangement of the weight-reducing structures 28 is not limiting. For example, Figures 8 to 10 illustrate a first type of weight-reducing structure 28, while Figures 11 to 13 illustrate a second type of weight-reducing structure 28. The weight-reducing structure 28 can extend through the lateral arm 21 in the left-right direction.

[0088] The position limiting member 2 can be configured as a hollow member or a solid member as required. For example, when a weight-reducing structure 28 is provided, it can be configured as a solid member. When the size is larger, such as when the above-mentioned inclined surface is provided, it can be configured as a hollow structure. Weight reduction is achieved based on the requirements of use.

[0089] As shown in Figures 5, 9 and 12, optionally, a force-applying structure 26 is provided on the limiting member 2, and the force-applying structure 26 is provided away from the end of the limiting member 2 inserted into the limiting groove 11 along the direction in which the limiting member 2 is inserted into the limiting groove 11.

[0090] Specifically, the force-applying structure 26 is located at the upper end of the limiting member 2 and is mainly used for hand-holding or mechanical grasping. The figure shows that it extends forward in the front-to-back direction. Before or after assembly, the limiting member 2 can be disassembled and assembled by applying force to the force-applying structure 26.

[0091] Optionally, the force-applying structure 26 can be arranged to protrude forward or to the left and right sides, thereby facilitating force application in the up and down directions while occupying less space.

[0092] In the above embodiment, optionally, the wire seat 1 includes a first section 1a and a second section 1b distributed in sequence, the cross-sectional area of ​​the first section 1a is smaller than the cross-sectional area of ​​the second section 1b, the limiting groove 11 is formed in the first section 1a, and the second section 1b is used to form a stop portion 12.

[0093] Specifically, the end surface of the second section 1b close to the first section 1a forms the stop portion 12, so that the structure of the wire passing seat 1 is simple, and the stop portion 12 and the rear end edge of the wire passing hole 31 can obtain a relatively large contact area.

[0094] As shown in FIG. 2 , optionally, the cross-sectional shapes of the wire hole 31 and the wire seat 1 are both rectangular.

[0095] This can prevent the wire passing seat 1 from rotating relative to the wire passing hole 31 when it is inserted into the wire passing hole 31 .

[0096] As shown in Figure 2, optionally, the above embodiment further includes a gasket 4, and a gasket 4 is provided between the stop portion 12 and the edge of the wire hole 31 and / or between the limiting member 2 and the edge of the wire hole 31 (it should be understood that in the latter case, the limiting member 2 presses the gasket 4 against the edge of the wire hole 31).

[0097] The gasket 4 can ensure the sealing of the connection between the wire seat 1 and the wire hole 31. Gaskets 4 of different thickness specifications can also be used as needed to meet the size adjustment requirements in the front and rear directions, thereby ensuring that the stop part 12 and the limit part 2 are respectively engaged with the edges of the wire hole 31.

[0098] In a second aspect, the present disclosure provides an electrical device comprising the line connection assembly of the above embodiment.

[0099] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present disclosure.
