The invention provides a wearable device, which can be understood as comprising: the wrist-watch, intelligent wrist-watch or intelligent bracelet of wearing in the wrist, can wear the motion monitoring module of ankle to and can wear in the 3D display device of head etc..

In the present invention, referring to fig. 1 to 3, 9, 10, 13, 14 and 16, the wearable device includes:

an apparatus main body 10, a belt body 20;

a mounting groove (hereinafter, the mounting groove is referred to as a "first mounting groove 110" in order to distinguish from a "second mounting groove" provided at an end portion of the belt body 20, and the "first mounting groove 110" is a mounting groove provided at an end portion of the apparatus main body 10), which is provided at an end portion of the apparatus main body 10, and in which a groove depth direction of the first mounting groove 110 is provided in parallel with or at an acute angle to a thickness direction of the apparatus main body 10; and

the plug connector 30 is disposed at an end of the belt body 20, and the plug connector 30 is inserted into and clamped in the first mounting groove 110, so that the belt body 20 is locked to the device main body 10.

In the prior art, two mounting grooves are arranged at two ends of the equipment main body in a back-to-back manner, and the end part of the belt body is inserted into the mounting groove, so that the assembly of the belt body and the equipment main body is completed. However, when the belt body is pulled, the direction of the pulling force is parallel to the depth direction of the mounting groove, so that the end of the belt body is easily pulled out of the mounting groove, and the belt body is separated from the device main body.

In the wearable device of the present invention, the depth direction of the first mounting groove 110 is parallel to or acute-angled with respect to the thickness direction of the device body 10, and when the band body 20 is pulled, the pulling force applied to the plug 30 is angled with respect to the groove sidewall of the first mounting groove 110, and the reaction force generated by the sidewall of the first mounting groove 110 with respect to the plug 30 at least partially offsets the pulling force, so that the plug 30 is not easily pulled out of the first mounting groove 110.

Specifically, the pulling force T applied to the plug 30 can be decomposed into a first component force F1 toward the groove side wall of the first mounting groove 110 and a second component force F2 in the groove depth direction of the first mounting groove 110, that is, a pulling force F capable of pulling the plug 30 out of the first mounting groove 110. The first component F1 is also a pressing force N1 that the plug 30 applies to the slot side wall of the first mounting slot 110, whereby the plug 30 can receive a reaction force (pressing force N2) of the slot side wall of the first mounting slot 110, and the second component F2 is also a pulling force that can pull the plug 30 out of the first mounting slot 110.

As shown in fig. 16, when the groove depth direction of the first mounting groove 110 is parallel to the thickness direction of the apparatus body 10, the pulling force T does not have a component in the groove depth direction of the first mounting groove 110, i.e., the second component F2 is zero, and the first component F1 can be offset by the pressing force N2, so that the plug 30 can be stably inserted into the first mounting groove 110.

As shown in fig. 2 to 4, when the groove depth direction of the first mounting groove 110 is set at an acute angle to the thickness direction of the apparatus main body 10, the first component force F1 is cancelled by the pressing force N2, and the effective force of the tensile force T is reduced. In addition, due to the existence of the second component force F2 and the extrusion between the plug 30 and the side wall of the first mounting groove 110, the plug 30 is still subjected to a friction force F opposite to the second component force F2, and the friction force F can partially or completely counteract the second component force F2, so that the effective acting force of the pressure T can be further reduced or completely reduced, and the plug 30 can be stably clamped in the first mounting groove 110.

In addition, in the existing wearable equipment, the assembly and disassembly processes of the band body and the equipment main body are very complicated, for example, in the traditional watch, a watchband is fixed on a dial plate through fasteners such as a raw ear, a watchband fixing groove is processed on the watchband, when the watch is assembled, the raw ear is required to penetrate into a watchband raw ear hole position arranged at the head position of the watchband, and the raw ear nails at two ends are completely inserted into the watchband fixing groove by aligning the two ends of the raw ear with the watchband fixing groove and stirring a raw ear poking rod; the disassembly mode is similar, and the ear-generating deflector rod also needs to be stirred, so that the ear nail on one side firstly exits from the watchband fixing groove, and then the watchband is integrally taken down. The disassembly and assembly are very complicated, and the user is inconvenient to operate. Because of giving birth to the ear size little, lead to in watchband assembly and dismantlement process, give birth to the operation that counterpoint and the driving lever of ear nail slided comparatively difficult, caused the inconvenience of changing the watchband.

In the wearable device of the present invention, the size of the plug 30 and the size of the first mounting groove 110 are both large, and therefore, the alignment of the plug 30 with the first mounting groove 110 is relatively simple. Moreover, the connector 30 is inserted into the first mounting groove 110, and the connector 30 is fastened to the first mounting groove 110, so that the assembly of the tape body 20 and the device main body 10 is completed; the connector 30 is pulled out from the first mounting groove 110, and the tape body 20 is completely detached from the device body 10. Therefore, in the wearable device of the present invention, the operation procedure for detaching and attaching the band 20 and the device body 10 is simplified, so that the user can replace the band 20 conveniently and quickly, thereby improving the operation experience of replacing the band 20.

Further, referring to fig. 2, fig. 3, fig. 6, fig. 9 to fig. 11, fig. 13 and fig. 14, the plug 30 includes a main body 400, the main body 400 includes a plug section 410 and a tongue section 420 disposed at one end of the plug section 410, the plug section 410 is connected to the belt body 20 through the tongue section 420, and after the plug section 410 is inserted into the first mounting groove 110, the tongue section 420 abuts against the notch of the first mounting groove 110. It is understood that the body 400, which is composed of the insertion section 410 and the tongue section 420, is generally L-shaped or T-shaped. When assembling the belt body 20 and the device main body 10, the insertion section 410 should be inserted into the first installation groove 110, and when the tongue body section 420 abuts against the notch of the first installation groove 110, the insertion section 410 is inserted in place, and at this time, the plug connector 30 can also be clamped in the first installation groove 110, so that the belt body 20 and the device main body 10 are locked.

In some embodiments, the plug section 410 is provided with a first limiting portion, the first mounting groove 110 is correspondingly provided with a second limiting portion, and after the plug section 410 is inserted into the first mounting groove 110, the first limiting portion is limited by the second limiting portion, so that the plug section 410 cannot be separated from the first limiting portion, and the plug element 30 is clamped in the first mounting groove 110. Thus, the belt body 20 and the main body 10 are locked together, so that the belt body 20 and the main body 10 are stably connected.

Further, referring to fig. 3 to 5, 10, 11 and 14, an end of the insertion section 410 away from the tongue section 420 is convexly provided to two sides to form a first limiting protrusion 411 as a first limiting portion; two sides of the first mounting groove 110 protrude relatively to form a second limiting clamping protrusion 112 as a second limiting part; after the inserting section 410 is inserted into the first mounting groove 110, the first limiting protrusion 411 is engaged with the second limiting protrusion 112 at a side away from the tongue section 420. Thus, when the inserting section 410 is inserted into and pulled out of the first mounting groove 110, both sides of the first limiting clamping protrusion 411 can contact the second limiting clamping protrusion 112, and the stress of the inserting section 410 can be more uniform. When the inserting section 410 is inserted into the first mounting groove 110 to a proper position, the tongue body section 420 abuts against the notch of the first mounting groove 110, and the first limiting protrusion 411 is located on one side of the second limiting protrusion 112 away from the tongue body section 420, so that the displacement of the inserting section 410 in the extending direction of the first mounting groove 110 is limited, and the inserting member 30 can be ensured to be clamped in the first mounting groove 110, so as to further improve the connection stability between the belt body 20 and the device main body 10. Of course, in other embodiments, a side of the end of the plug section far away from the tongue section may be convexly provided with a first limiting protrusion, and a side of the first mounting groove is correspondingly provided with a second limiting protrusion, so that the first limiting protrusion is limited by the second limiting protrusion, and the plug section is clamped in the first mounting groove.

Further, referring to fig. 3, 4, 10 and 14, the notch of the first mounting groove 110 is provided with a guiding section 114, and the guiding section 114 has a tapered structure for guiding the plug 30 to be inserted into the mounting groove. The inlet of the guide section 114 is located at the outer side of the notch of the first mounting groove 110, the outlet is located at the inner side of the notch of the first mounting groove 110, and the guide section 114 has a tapered structure, that is, the width of the guide section 114 gradually increases in the direction extending from the outlet to the inlet. In the process of inserting the plug-in unit 30 into the first installation slot 110, the plug-in unit 30 needs to pass through the guide section 114, specifically, the first limiting protrusion 411 on the plug-in unit 410 contacts with the entrance of the guide section 114 first, the width of the entrance of the guide section 114 should be slightly larger than the width of the first limiting protrusion 411, so that the first limiting protrusion 411 enters the guide section 114, and then the first limiting protrusion 411 gradually enters the first installation slot 110 under the guidance of the guide section 114 until the tongue body section 420 abuts against the entrance of the guide section 114, so that the plug-in unit 410 is integrally inserted into the first installation slot 110.

Without loss of generality, in one embodiment, as shown in fig. 3, 10 and 14, the second limit stop 112 extends to the notch of the first mounting groove 110, i.e., the outlet of the guide section 114 is directly connected to the second limit stop 112. At this moment, can set up the material of first spacing calorie of protruding 411 into the elastic material, so, the width along with guide section 114 reduces to the size of the groove width of the first mounting groove 110 of the protruding 112 department of second spacing calorie, and when being less than the width of the protruding 411 of first spacing calorie, first spacing calorie of protruding 411 can suitable elastic compression, until first spacing calorie of protruding 411 crosses the protruding 112 of second spacing calorie, reach the protruding 112 one side that deviates from guide section 114 of second spacing calorie of 112, also represent that grafting section 410 pegs graft and targets in place, first spacing calorie of protruding 411 also can receive the spacing of the protruding 112 of second spacing calorie, and make plug connector 30 be blocked admittedly in first mounting groove 110.

In some embodiments, as shown in fig. 6 and 9, the end of the belt body 20 is provided with a second mounting groove 210, the plug 30 is disposed in the second mounting groove 210, and after the plug 30 is inserted into the first mounting groove 110, the first mounting groove 110 is received in the second mounting groove 210. In this way, after the plug-in unit 30 is inserted in place, the first mounting groove 110 is accommodated in the second mounting groove 210, and the first mounting groove 110 can be protected. Particularly, when the groove depth direction of the first mounting groove 110 is set to be an acute angle with the thickness direction of the device body 10, the plug connector 30 is also set to be an included angle with the thickness direction of the device body 10, at this time, the groove wall of the second mounting groove 210 can be extended to connect the plug connector with the end of the device body 10, and the extending angle of the groove wall is adjusted to realize smooth transition between the device body 10 and the belt body 20, so as to improve the appearance beauty of the wearable device. The tongue body 420 can be directly used as a wall of the second mounting groove 210, or the tongue body 420 is disposed on the wall of the second mounting groove 210. Of course, in other embodiments, the tongue segment may be opposite to and spaced apart from a groove wall of the second mounting groove.

Further, in an embodiment, the extension direction of the plug section 410 is toward the wearing side of the band body 20, that is, the band body 20 is attached to the skin of the human body after the user wears the wearable device. It is understood that neither the side of the second mounting groove 210 opposite to the end of the apparatus body 10 nor the side near the end of the plug section 410 is provided with a groove wall. After the plug 30 is inserted into the first mounting groove 110, one side of the second mounting groove 210 opposite to the end of the device body 10 is connected to the end of the device body 10, in this embodiment, the side of the second mounting groove 210 close to the end of the plug section 410 is arranged on the wearing side, and after the user wears the wearable device, the side does not need to be exposed, and the appearance aesthetic degree of the wearable device can be further improved.

In some embodiments, as shown in fig. 3, 4, 10, 14 and 16, the first mounting groove 110 has a first groove wall 111 disposed opposite to the end of the device body 10, and after the plug 30 is inserted into the first mounting groove 110, the first groove wall 111 is clamped between the groove wall of the second mounting groove 210 and the plug 30. Specifically, the first groove wall 111 is to be fixed between the body 400 and the groove wall of the second mounting groove 210. Thus, the plug 30 is less likely to be disengaged from the first mounting groove 110, and the connection stability of the belt body 20 and the device main body 10 can be further improved. Alternatively, as shown in fig. 16, the first groove wall 111 may be a pin provided in a notch of the first mounting groove 110, and as shown in fig. 3, 4, 10, and 14, the first groove wall 111 may be formed by a housing of the apparatus main body 10.

Further, as shown in fig. 6 and 11, the tongue body section 420 is provided with a clamping protrusion 421 protruding toward the device main body 10, as shown in fig. 3, 4, 10 and 14, the end of the device main body 10 is further provided with a clamping groove 115, and after the inserting section 410 is inserted into the first mounting groove 110, the clamping protrusion 421 is correspondingly clamped into the clamping groove 115. It can be understood that the clamping protrusion 421 is disposed on the side of the tongue body segment 420 that is away from the main body portion 400 of the belt body 20, and the clamping grooves 115 at the two ends of the device main body 10 are disposed back to back, that is, the notches of the clamping grooves 115 are disposed opposite to the end of the belt body 20, so that in the process of inserting the inserting section 410 into the first installing groove 110, the clamping protrusion 421 is opposite to the end of the device main body 10 until the inserting section 410 is inserted in place, the tongue body segment 420 abuts against the notches of the first installing groove 110, and the clamping protrusion 421 is correspondingly clamped into the clamping grooves 115. After the strap 20 is pulled, a seam may be formed between the groove wall of the second mounting groove 210 and the end of the device body 10, and the clamping protrusion 421 has a certain height, so that even if the clamping protrusion 421 partially breaks away from the clamping groove 115, a gap is not formed between the clamping protrusion 421 and the end of the device body 10, which is beneficial to ensuring the aesthetic appearance of the wearable device.

In some embodiments, as shown in fig. 2, 9 and 13, the plug 30 further includes a reinforcing structure 500 embedded in the main body 400, and the reinforcing structure 500 is inserted into the first mounting groove 110 along with the plug section 410. The structural strength of the reinforcing structure member 500 is large, therefore, the reinforcing structure member 500 is together inserted along with the inserting section 410 and is located behind the first mounting groove 110, even if the belt body 20 is dragged, the pulling force is transmitted to the inserting member 30, under the support of the reinforcing structure member 500, the main body part 400 is not easy to deform, that is, the reinforcing structure member 500 is embedded behind the main body part 400, the structural strength of the inserting member 30 can be effectively improved, the connection stability of the inserting member 30 and the first mounting groove 110 is favorably ensured, and the capability of resisting dragging of the inserting member 30 can be improved.

Further, the opposite sides of the reinforcing structure 500 are provided with first limiting structures, the two sides of the first mounting groove 110 are correspondingly provided with second limiting structures, and after the reinforcing structure 500 is inserted into the first mounting groove 110, the first limiting structures are matched with the second limiting structures, so that the plug connector 30 cannot be automatically separated from the first mounting groove 110. In this way, the plug-in unit 30 can be also locked in the first mounting groove 110. In the wearable device of the present invention, the first limiting portion of the insertion section 410 may be matched with the second limiting portion of the first mounting groove 110 alone, or the first limiting structure of the reinforcing structure 500 may be matched with the second limiting structure of the first mounting groove 110 alone, so as to clamp the plug-in unit 30 in the first mounting groove 110, or both of these two methods may be applied simultaneously, so as to improve the clamping effect of the plug-in unit 30.

Further, as shown in fig. 7 and 12, the first limiting structure is configured as a limiting protrusion 501, as shown in fig. 3, 4 and 10, the second limiting structure is configured as a limiting groove 113, and after the reinforcing structure 500 is inserted into the first mounting groove 110, the limiting protrusion 501 is inserted into the limiting groove 113, i.e., the plug connector 30 can be fixed in the mounting groove by the way of the limiting reinforcing structure 500. Particularly, still can all set up spacing arch 501 in the relative both sides of additional strengthening structure 500, correspondingly, spacing groove 113 is all seted up in the relative both sides of first mounting groove 110, so, two spacing arch 501 on additional strengthening structure 500 are gone into the spacing groove 113 of first mounting groove 110 both sides respectively, not only can promote the limiting action to additional strengthening structure 500, can also be at the in-process of plug connector 30 plug, it is even to make additional strengthening structure 500 both sides atress, be favorable to guaranteeing additional strengthening structure 500's structural strength. Of course, the first limiting structure can be set as a limiting groove, the second limiting structure can be set as a limiting protrusion, and the reinforcing structure can be clamped and fixed.

Further, the limiting protrusion 501 and the limiting groove 113 are arranged in an arc-shaped structure. So, spacing arch 501 business turn over spacing groove 113 is more laborsaving, can also reduce the effort between spacing arch 501 and the spacing groove 113 in addition, is favorable to ensureing the structural strength who strengthens structure 500.

Further, the limiting protrusion 501 is elastically contractibly disposed on the reinforcing structure 500. When the limiting protrusion 501 is matched with the other positions of the first mounting groove 110 except the limiting groove 113, the limiting protrusion 501 can be contracted into the reinforcing structure member 500 by the action force of the groove wall to reduce the interaction force between the limiting protrusion 501 and the groove wall of the first mounting groove 110, and when the limiting protrusion 501 reaches the limiting groove 113, the limiting protrusion 501 can be released and can be clamped in the limiting groove 113. Thus, the limiting protrusion 501 can enter and exit the limiting groove 113 more laborsavingly, and the structural strength of the reinforced structural member 500 can be further ensured.

In one embodiment, as shown in fig. 7 and 8, the reinforcing structure 500 includes a housing 510 and a limiting bead 520 disposed on both sides of the housing 510, and the limiting bead 520 has a portion exposed outside the housing 510 as a limiting protrusion 501. In this embodiment, the limiting bead 520 is a sphere, so that the outer contour of the limiting protrusion 501 is a spherical surface, which can reduce the contact area between the limiting protrusion 501 and the wall of the first mounting groove 110, and is beneficial to reducing the friction force applied to the limiting protrusion 501 in the first mounting groove 110. Particularly, the limiting groove 113 may also be a spherical groove, so that the limiting protrusion 501 and the limiting groove 113 can be matched more, and the fastening effect of the plug 30 is ensured. In addition, in order to ensure that the limiting beads 520 can be stably installed in the installation hole 512, the diameter of the installation hole 512 and the diameter of the limiting beads 520 should be properly adjusted to prevent the limiting beads 520 from coming off the housing 510. Without loss of generality, in the embodiment, the mounting hole 512 is a tapered hole, the diameter of the mounting hole 512 gradually decreases in a direction from the inside of the housing 510 to the outside of the housing 510, and at least the diameter of the mounting hole 512 at the outside of the housing 510 is smaller than the diameter of the limiting bead 520, so that the limiting bead 520 cannot fall out of the housing 510 from the mounting hole 512.

Further, as shown in fig. 7, mounting holes 512 are formed at both sides of the housing 510, and the position limiting beads 520 are rollably mounted in the mounting holes 512. Therefore, the friction between the limiting protrusion 501 and the wall of the first mounting groove 110 can be changed from sliding friction to rolling friction, and the friction force applied by the limiting protrusion 501 in the first mounting groove 110 can be further reduced.

Further, as shown in fig. 5 and 7, a receiving groove 511 is formed in the housing 510, an elastic element 530 is received in the receiving groove 511, and the elastic element 530 is disposed between the two limiting beads 520; under the action of the elastic member 530, the position-limiting bead 520 can movably protrude out of the housing 510, so that the position-limiting protrusion 501 can elastically contract. Without loss of generality, in the embodiment, during the insertion of the plug 30 into the first mounting groove 110, the limiting beads 520 are pressed against the elastic member 530 after being acted by the groove wall of the first mounting groove 110, so that the elastic member 530 is compressed. Therefore, the two position-limiting beads 520 are retracted into the receiving groove 511, so that the position-limiting beads 520 do not have an exposed portion, or the interference between the exposed portion of the position-limiting beads 520 and the groove wall of the first mounting groove 110 is small, thereby facilitating the insertion of the plug connector 30 into the first mounting groove 110. When the position-limiting bead 520 reaches the position of the position-limiting groove 113, the outer portion of the position-limiting bead 520 is not squeezed by the groove wall due to the increase of the groove width, and the position-limiting bead 520 protrudes out of the housing 510 under the elastic force of the elastic member 530 until abutting against the groove wall of the position-limiting groove 113. At this time, the elastic member 530 is just restored to the natural state or still in the elastically compressed state, so that the position-limiting bead 520 can be maintained in the state of being engaged with the position-limiting groove 113. Without loss of generality, in this embodiment, the elastic member 530 is provided as a spring, and the position-limiting bead 520 is provided as metal. Thus, when the position restricting ball 520 falls into the position restricting groove 113, a sound is generated to prompt the user that the plug-in unit 30 is inserted in place. Certainly, in other embodiments, the elastic member may also be elastic rubber, elastic silica gel, elastic plastic, etc., so that after the pressure is applied, the elastic member can be elastically compressed, and after the pressure is released, the elastic member can be restored to the original state, and the limiting bead can also movably protrude out of the housing; the limiting beads can also be made of hard plastics, hard rubber and the like.

Further, as shown in fig. 5, 7 and 8, the reinforcing structure 500 further includes a cover plate 540, the cover plate 540 covers the receiving groove 511, the cover plate 540 has a limiting rib 541 extending toward the receiving groove 511, and the elastic element 530 is limited between the end of the limiting rib 541 and the bottom wall of the receiving groove 511. The end of the limiting rib 541 is close to the spring or supports against the spring, under the limiting action of the limiting rib 541, the elastic member 530 will deform along the axial direction of the mounting hole 512 between the two limiting beads 520, the elastic member 530 will not be dislocated, and can stably provide acting force for the limiting beads 520, and the limiting beads 520 will not fall off into the accommodating groove 511, and can be stably installed in the mounting hole 512. In addition, in order to improve the connection stability of the reinforcing structure 500 and the main body 400, a cover plate 540 may be embedded in the tongue portion.

Without loss of generality, the assembly of the reinforced structural member 500 in the present embodiment may be performed with reference to the following steps:

the housing 510 is first placed securely in the tooling. Optionally, the housing 510 is held fixed to the tool by magnetic attraction. Specifically, at least one of the housing 510 and the tool is a magnet, and at most one of the housing 510 and the tool is a magnetic metal, so that the housing 510 and the tool can be directly attracted, or the housing 510 is made of a magnetic metal material, and is attracted to the housing 510 through the magnet on the side of the tool away from the housing 510. Of course, in other embodiments, a limiting structure for fixing the housing may be provided in the tool.

Then, the two position restricting beads 520 are fitted into the fitting hole 512. Optionally, the limiting bead 520 is made of magnetic metal, a magnet is arranged on the tool opposite to the mounting hole 512, the limiting bead 520 is placed in the accommodating groove 511, and the magnet can suck the limiting bead 520 into the mounting hole 512.

Then, the spring is clamped into the accommodating groove 511 by the tool clamp, and the spring is located between the two limiting beads 520.

Finally, the cover 540 is covered on the receiving groove 511, thereby completing the assembly of the reinforced structural member 500.

In addition, after the reinforcing structure 500 is assembled, it may be embedded in the main body 400 by bonding, or may be integrally formed with the main body 400 by insert molding.

In another embodiment, as shown in fig. 12, two opposite sides of the reinforcing structure 500 are respectively provided with a flexible cantilever 550, and the opposite sides of the two flexible cantilevers 550 are provided with the limiting protrusions 501. After the plug-in unit 30 is inserted into the first mounting groove 110, the groove walls act on the limiting protrusion 501, and the two elastic cantilevers 550 elastically move towards each other, so that the limiting protrusion 501 contracts towards the inner side of the reinforcing structure 500, thereby reducing the interference between the limiting protrusion 501 and the groove walls of the first mounting groove 110.

Without loss of generality, in the embodiment, the reinforcing structure 500 is provided with a through groove penetrating through two sides, two elastic cantilevers 550 are arranged relative to the through groove, one end of each elastic cantilever 550 is connected to the side of the through groove, the other end of each elastic cantilever 550 is a free end, and the limiting protrusion 501 is arranged close to the free end. The main body 400 is made of elastic material, such as soft plastic, rubber, silica gel, etc., the reinforcing structure 500 is made of hard plastic or metal, and when the belt body 20 is processed, the main body 400 and the reinforcing structure 500 are integrally formed in an insert injection molding mode, and the through grooves are filled with elastic material. After the limiting protrusions 501 are stressed, the free ends of the elastic cantilevers 550 slightly swing towards the through grooves, the main body 400 is compressed to the portion in the through grooves, the elastic material of the portion is elastically compressed, the two limiting protrusions 501 are driven to move towards each other, so that the distance between the two limiting protrusions 501 is approximately equal to the width of the first installation groove 110, and the plug-in unit 30 can be conveniently inserted into the first installation groove 110. Until the limiting protrusion 501 reaches the limiting groove 113, at this time, since the groove width is increased, the portion of the main body 400 located in the through groove tends to recover to the original shape, so that the elastic cantilever 550 is released, and the elastic cantilever 550 is reset, i.e., the limiting protrusion 501 is clamped in the limiting groove 113.

Of course, in other embodiments, the reinforcing structure and the main body may be separately formed and then connected by bonding, or the main body may be sleeved outside the reinforcing structure to connect the reinforcing structure and the main body, the elastic cantilever should be exposed outside the main body, and a space may be provided between the elastic cantilever and the side of the reinforcing structure, wherein a part of the side opposite to the elastic cantilever may be partially or completely hollowed to provide the elastic cantilever with a contracted space.

In yet another embodiment, as shown in fig. 13 and 14, the reinforcing structure 500 is provided as a solid structure. In this embodiment, the outside of the reinforcing structure 500 does not have a limiting structure, and the reinforcing structure 500 mainly has the effect of improving the structural strength of the plug connector 30 so as to reduce the probability of inelastic deformation of the plug connector 30 when the belt body 20 is pulled by an external force, thereby ensuring that the plug connector 30 can be stably clamped in the first mounting groove 110.

In any of the above embodiments, as shown in fig. 6, 8, 11, 12 and 15, the reinforcing structure 500 has a plurality of embedding protrusions 560 at two sides thereof, the main body 400 has a plurality of embedding grooves 430 at two sides thereof, and one of the embedding protrusions 560 is correspondingly received in one of the embedding grooves 430 to limit the separation of the reinforcing structure 500 from the main body 400. It is understood that the reinforcing structure member 500 and the main body 400 may be formed separately and then connected by bonding, or the main body 400 is sleeved outside the reinforcing structure member 500 to connect them, and the reinforcing structure member 500 may also be formed integrally with the main body 400 by insert molding. No matter what way the two are connected, the engagement between the insertion protrusion 560 and the insertion groove 430 can improve the connection stability between the main body 400 and the reinforcing structure 500, so that the reinforcing structure 500 is not easily separated from the main body 400 even if the plug-in connector 30 is frequently inserted and removed. In addition, in order to further improve the connection stability between the reinforcing structure 500 and the main body 400, the reinforcing structure 500 is arranged in an L shape or a T shape corresponding to the main body 400, and the reinforcing structure 500 is embedded in the main body 400 in an adaptive manner.
