Description

Technical Field

[0001] The invention relates to the technical field of automobile safety belts, and in particular to a safety belt connector. Background Art

[0002] In the seat belt device, in order to facilitate the retraction of the webbing into the retractor and the seat flipping, a connector device is usually provided at the lower fixing point of the seat belt to achieve the separation and connection between the retractor and the fixing point under the vehicle body. When the occupant is wearing the belt normally or during a collision, there must be no risk of the connector being mis-detached. The seat belt connector is generally provided with an anti-dissociation structure to limit the button of the seat belt connector to avoid the problem of mis-detachment of the connector in a collision event.

[0003] In the prior art, a leaf spring or a long elastic member is used in a seat belt connector as an anti-dissociation structure to limit and block the button of the connector to prevent the connector from being mis-dissociated in the event of a collision. However, since the existing anti-dissociation structure in the form of a leaf spring is directly assembled on the shell, it is necessary to pay attention to the coordination between the anti-dissociation structure and the bracket and the button during assembly so that the leaf spring and the button remain corresponding. This undoubtedly complicates the installation process of the anti-dissociation structure and increases the workload of the staff.

[0004] Based on this, a new technical solution is needed. Summary of the invention

[0005] In view of this, an embodiment of the present invention provides a safety belt connector to at least solve the problem that the existing anti-dissociation structure is installed on the housing, resulting in a complicated assembly process.

[0006] The embodiment of the present invention provides the following technical solutions:

[0007] The embodiment of the present invention provides a seat belt connector, including a housing, a bracket, a latch, a locking pin and a button, wherein:

[0008] The housing is formed with an internal space for accommodating the bracket, the locking pin and the button, and an opening for inserting the latch;

[0010] The button includes two button side walls and a button spring that are arranged opposite to each other. The two button side walls are respectively engaged with the two ends of the locking pin, and the two button side walls have a tendency to drive the locking pin to move from the disengaged position to the locked position under the action of the button spring. The seat belt connector also includes:

[0011] An anti-dissociation spring, the anti-dissociation spring is an integrally arranged leaf spring component, comprising a pre-installation portion and a supporting top portion, the pre-installation portion being connected to the two side walls of the bracket, the supporting top portion being biased toward the outer side of the bracket side wall under the action of the pre-installation portion or its own elasticity, and being configured to support the end of the button side wall to prevent the locking pin from moving toward the dissociation position.

[0013] The support top is configured to be located at one end of the bracket side wall away from the button connecting wall, and when the button drives the locking pin to move to the locking position, it is opposite to the outer side of the end of the button side wall. When the button is pressed to drive the locking pin to move to the disengagement position, the anti-disengagement spring is supported by the reaction of the shell, so that the support top is supported on the outer side of the end of the button side wall.

[0014] Further, the pre-installation portion is elastically clamped at the other end of the two bracket side walls away from the bracket connecting arm, and the pre-installation portion sequentially includes a first elastic arm, a first connecting arm, a second elastic arm, a second connecting arm, a third elastic arm, a third connecting arm and a fourth elastic arm, and the support top is connected to the fourth elastic arm.

[0027] When the slider is not affected by the inserted latch, the slider is used to support and limit the locking pin in the locked position under the action of the slider spring and the two protrusions, and the support top is pressed against a side surface of the button side wall; when the slider is affected by the latch, the slider compresses the slider spring so that the slider releases the limit on the locking pin, so that the locking pin can move to the disengaged position, and the support top is pressed against one side of the bracket side wall and opposite to the outer side of the end of the button side wall.

[0028] Compared with the prior art, the at least one technical solution adopted in the embodiment of the present invention can achieve the following beneficial effects:

[0029] A safety belt connector of the present invention connects the pre-installed parts of the anti-disengagement spring to the two opposite side walls of the bracket, and after the locking pin moves to the locking position and engages with the latch, the supporting top part is supported on the end of the button side wall by the pre-installed parts to limit the button side wall from moving to the disengagement position, and the locking pin is stably maintained in the locking position, thereby solving the problem of complicated assembly process after the anti-disengagement structure is installed on the housing in the prior art;

[0030] Furthermore, due to the limited internal space of the shell, when the support top supports the side wall of the button, the displacement of the support top and the pre-installed part will be restricted by the shell to achieve the limitation of the anti-dissociation spring, thereby solving the problem of the existing anti-dissociation structure lacking effective limitation after installation.

[0059] Additionally, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the examples can be practiced without these specific details.

[0060] Patent application No. 200710091399.9 discloses an assembly structure in which a plate-like elastic component is directly mounted on a housing 10 and its internal structure is relatively complex. Therefore, when assembling the housing 10, attention must be paid to whether the plate-like elastic component is properly installed. This undoubtedly increases the difficulty of assembly and reduces the work efficiency of the staff.

[0061] In addition, the existing plate-like elastic component also lacks limitation in the left-right direction, so that after long-term use, there is a risk of displacement of the plate-like elastic component, which in turn causes device failure and makes it impossible to limit the button 50 of the lock.

[0062] Based on this, this specification embodiment proposes a processing solution: Figure 1 As shown, a seat belt connector of the present invention installs the pre-installed portion 61 of the anti-dissociation spring 60 on the two bracket side walls 21, and biases the supporting top portion 62 toward the outer side of the bracket side wall 21 to support the end of the button side wall 51, thereby preventing the locking pin 40 from moving toward the dissociated position. Therefore, when assembling the shell 10, the shell 10 can be directly buckled on the outside of the bracket 20, the locking pin 40 and the button 50, without having to pay attention to the assembly process of the leaf spring all the time, thereby solving the problem of the existing anti-dissociation structure being installed on the shell 10, which leads to complicated assembly process.

[0063] The technical solutions provided by various embodiments of the present application are described below in conjunction with the accompanying drawings.

[0064] Example 1

[0065] like Figures 1 to 9 As shown, a seat belt connector of the present invention includes a housing 10, a bracket 20, a latch 30, a locking pin 40 and a button 50, wherein the housing 10 is formed with an internal space for accommodating the bracket 20, the locking pin 40 and the button 50 and an opening for inserting the latch 30; the bracket 20 includes two bracket side walls 21 arranged opposite to each other, and the two bracket side walls 21 are respectively formed with slide grooves 22, the locking pin 40 is inserted into the two slide grooves 22, and the two ends of the locking pin 40 extend to the outside of the two bracket side walls 21, and can be displaced between a locking position engaged with the latch 30 and a disengaged position disengaged from the latch 30; the button 50 includes two button side walls 51 and a button spring 52 arranged opposite to each other, the two button side walls 51 are respectively engaged with the two ends of the locking pin 40, and the two button side walls 51 have a tendency to drive the locking pin 40 to move from the disengaged position to the locking position under the action of the button spring 52.

[0066] The housing 10 is used for protection and installation, and may include a first cover plate and a second cover plate that are buckled together to form an internal space for accommodating the bracket 20, the locking pin 40 and the button 50.

[0067] like Figure 5 As shown, one of the bracket side walls 21 is longer than the other bracket side wall 21, and a safety belt through hole is provided on the portion of the bracket side wall 21 that is longer than the other bracket side wall 21 to connect with the safety belt. When both bracket side walls 21 are placed in the housing 10, a through hole corresponding to the safety belt through hole is formed on the housing 10.

[0068] Furthermore, the top ends of the two bracket side walls 21 are set to be substantially flush, and one end of the two bracket side walls 21 is connected by a bracket connecting wall 23, so that a U-shaped groove is formed between the two bracket side walls 21. At this time, only the portion between the two bracket side walls 21 where the bracket connecting wall 23 is provided is closed.

[0069] Preferably, the slide grooves 22 on the two bracket side walls 21 are horizontally arranged to correspond to each other, so as to facilitate the insertion of the locking pin 40 and prevent the locking pin 40 from sliding out of the two slide grooves 22 .

[0070] Among them, the side wall of the slide groove 22 supporting the locking pin 40 can be provided with a slope, so that when the locking pin 40 is not subjected to external force, the locking pin 40 has a tendency to move to the locking position engaged with the latch 30, so that after the button spring 52 fails or partially fails, the locking pin 40 can still remain in the locked position.

[0071] For example, the slope may range from 5° to 15°.

[0072] The locking pin 40 is used to be detachably connected to the latch 30, such as snap-fitting, to prevent the latch 30 from being dissociated.

[0073] For example, a snap-fit ​​groove is provided on the latch 30 , and when the snap-fit ​​groove of the latch 30 is located between the two slide grooves 22 , the locking pin 40 can be snapped into the snap-fit ​​groove to limit the latch 30 .

[0074] When the locking pin 40 is located at the locking position and the latch 30 is inserted between the two bracket side walls 21 , the locking pin 40 is engaged with the latch 30 ; when the locking pin 40 is located at the disengaging position, the locking pin 40 is disengaged from the latch 30 .

[0075] The locking pin 40 of the present application may be a rectangular parallelepiped structure, so as to increase the connection strength between the locking pin 40 and the latch 30 after being engaged with the engaging groove on the latch 30 .

[0076] like Figure 1 As shown, a plug hole is formed at the end of the button side wall 51 close to the locking pin 40, and the end of the locking pin 40 is embedded in the plug hole, so that the button side wall 51 can drive the locking pin 40 to move between the locking position and the disengaged position.

[0077] For example, the button side wall 51 is an L-shaped structure as a whole, and the insertion hole is opened at the end of the horizontal part of the button side wall 51.

[0078] The button spring 52 is disposed between the button 50 and the bracket 20 , and is used to drive the button side wall 51 to drive the locking pin 40 to move from the disengaged position to the locked position.

[0079] Furthermore, the button 50 also includes a button connecting wall 53, which is arranged between the two button side walls 51, so that the button 50 as a whole has a U-shaped structure. At this time, the button spring 52 is located between the bracket connecting wall 23 and the button connecting wall 53, and under the action of the elastic force of the button spring 52 itself, the button connecting wall 53 has a tendency to move away from the bracket connecting wall 23, and then the button connecting wall 53 makes the locking pin 40 have a tendency to move from the disengaged position to the locked position through the button side wall 51.

[0080] The button spring 52 may be a leaf spring or other structures.

[0081] like Figure 1 , 6 As shown in Figures 1 to 9, the seat belt connector also includes an anti-disengagement spring 60, which is an integral leaf spring component. The anti-disengagement spring 60 includes a pre-installation portion 61 and a support top portion 62. The pre-installation portion 61 is connected to the two bracket side walls 21. The support top portion 62 is biased toward the outer side of the bracket side wall 21 under the action of the pre-installation portion 61 or its own elasticity, and is configured to support the end of the button side wall 51 to prevent the locking pin 40 from moving to the disengaged position.

[0082] The pre-installed portion 61 is pre-installed on the two bracket side walls 21 , and is used to preliminarily fix the anti-dissociation spring 60 on the two bracket side walls 21 , and cooperate with the supporting top portion 62 to preliminarily support the button side wall 51 .

[0083] The connection method between the pre-installed portion 61 and the two bracket side walls 21 includes but is not limited to interference connection, bolt connection, riveting, etc.

[0084] After the pre-installed portion 61 is pre-installed on the two bracket side walls 21 , one end of the pre-installed portion 61 close to the support top 62 extends to the dissociation path of the button side wall 51 and drives the support top 62 to be biased toward the outer wall direction of the bracket side wall 21 .

[0085] Specifically, when the button side wall 51 moves to the disengagement position with the locking pin 40, the button 50 squeezes the button spring 52 and moves in the disengagement direction, so that the button side wall 51 moves between the support top 62 and the bracket side wall 21, and the support top 62 is pressed against the button side wall 51 under the bias of the pre-installation part 61; after the button side wall 51 drives the locking pin 40 to move to the locking position under the action of the button spring 52, the support top 62 separates from the button side wall 51 and supports the end of the button side wall 51 to prevent the button side wall 51 from moving in the disengagement direction, so as to prevent the locking pin 40 from moving to the disengagement position.

[0086] The present invention installs the anti-dissociation spring 60 on the bracket side wall 21, which not only supports the button side wall 51, but also facilitates the shell 10 to be buckled on the outside of the bracket 20, thereby solving the problem of the difficulty of assembling the plate-shaped elastic part on the shell 10 in the prior art.

[0087] like Figures 8-9 As shown, the support top 62 is configured to be located at one end of the bracket side wall 21 away from the button connecting wall 53, and when the button 50 drives the locking pin 40 to move to the locking position, it is opposite to the outer side of the end of the button side wall 51. When the button 50 is pressed to drive the locking pin 40 to move to the disengagement position, the anti-disengagement spring 60 is supported by the reaction of the shell 10, so that the support top 62 is supported on the outer side of the end of the button side wall 51.

[0088] Preferably, at least part of the anti-dissociation spring 60 abuts against the housing 10 so that when the anti-dissociation spring 60 is squeezed by the button side wall 51, the housing 10 can support the anti-dissociation spring 60 to prevent the anti-dissociation spring 60 from deviating in the dissociation direction and causing the anti-dissociation spring 60 to fail.

[0089] Furthermore, a transverse supporting rib 13 is provided on the inner wall of the shell 10, and the transverse supporting rib 13 is arranged corresponding to the pre-installation part 61 or the supporting top part 62, and is used to support the pre-installation part 61 and the supporting top part 62 to prevent the anti-dissociation spring 60 from being offset or displaced under the extrusion of the button side wall 51.

[0090] Specifically, when the anti-dissociation spring 60 is installed in the shell 10, the anti-dissociation spring 60 abuts against the transverse supporting rib 13, so that when the anti-dissociation spring 60 is squeezed by the button side wall 51, the anti-dissociation spring 60 is supported by the reaction of the transverse supporting rib 13, so that the supporting top 62 is supported on the outside of the end of the button side wall 51.

[0091] In some of the embodiments, Figure 4 As shown, a vertical supporting rib 14 is further provided on the inner wall of the shell 10, and the vertical supporting rib 14 is arranged vertically corresponding to the pre-installation part 61 or the supporting top part 62 to prevent the pre-installation part 61 or the supporting top part 62 from being displaced in the vertical direction.

[0092] Specifically, when the anti-dissociation spring 60 is installed in the shell 10, the anti-dissociation spring 60 abuts against the vertical supporting rib 14 to limit the displacement of the anti-dissociation spring 60 in the vertical direction, thereby preventing the anti-dissociation spring 60 from moving vertically due to vibration or other external factors, thereby causing the supporting top 62 to deviate from the outer side of the end of the button side wall 51.

[0093] like Figure 6 As shown, the pre-installation part 61 is elastically clamped on the other end of the connecting arm of the two bracket side walls 21 away from the bracket 20, and the pre-installation part 61 includes a first elastic arm 611, a first connecting arm 612, a second elastic arm 613, a second connecting arm 614, a third elastic arm 615, a third connecting arm 616 and a fourth elastic arm 617 in sequence, and the support top 62 is connected to the fourth elastic arm 617.

[0094] When the locking pin 40 is in the locking position, the first elastic arm 611 and the second elastic arm 613 are respectively attached to the two sides of one bracket side wall 21, the third elastic arm 615 and the support top 62 are respectively attached to the two sides of the other bracket side wall 21, the first connecting arm 612 and the third connecting arm 616 are respectively attached to the outer side of the other end of the two bracket side walls 21, and the second connecting arm 614 is placed between the two bracket side walls 21 and away from the other end thereof.

[0095] Specifically, Figure 7 As shown, the pre-installation portion 61 is in a bow-shaped structure as a whole, the first elastic arm 611 and the second elastic arm 613 are arranged opposite to each other, and the first connecting arm 612 is arranged between the first elastic arm 611 and the second elastic arm 613, so that the first elastic arm 611, the first connecting arm 612 and the second elastic arm 613 form a U-shaped structure as a whole to fit with a bracket side wall 21, so that the first elastic arm 611 and the second elastic arm 613 are respectively attached to the two sides of the bracket side wall 21; the second elastic arm 613 and the third elastic arm 615 are arranged opposite to each other, and the second connecting arm 614 is arranged between the second elastic arm 613 and the third elastic arm 615, and is located at the end of the second elastic arm 613 away from the first connecting arm 612 , so that a U-shaped structure is formed between the second elastic arm 613, the third elastic arm 615 and the second connecting arm 614, and is embedded between the two bracket side walls 21; the fourth elastic arm 617 and the third elastic arm 615 are arranged opposite to each other, and the third connecting arm 616 is arranged between the fourth elastic arm 617 and the third elastic arm 615, and the third connecting arm 616 is located at the end of the third elastic arm 615 away from the second connecting arm 614, so that the third elastic arm 615, the third connecting arm 616 and the fourth elastic arm 617 form a U-shaped structure, and surround the other bracket side wall 21, under the elastic force of the fourth elastic arm 617 and the support of other elastic arms and connecting arms, the support top 62 is buckled on the outside of the other bracket side wall 21.

[0096] Among them, by setting the pre-installation part 61 as a bow-shaped structure and embedding the pre-installation part 61 into the two bracket side walls 21, the installation of the pre-installation part 61 is facilitated, and the pre-installation part 61 can be initially limited and fixed.

[0097] Among them, by performing embedded pre-installation on the pre-installation part 61, during the installation and assembly process, it is convenient for the staff to adjust the position of the pre-installation part 61 so that the supporting top part 62 can correspond to the button side wall 51.

[0098] In some of the embodiments, a limiting plane 6111 is further provided on the first elastic arm 611. The limiting plane 6111 is provided on the first elastic wall 611. The limiting plane 6111 is provided corresponding to the vertical end of the bracket side wall 21, and is used to cooperate with the vertical supporting rib 14 to vertically limit the pre-installation part 61 to avoid vertical displacement of the pre-installation part 61.

[0099] Further preferably, there are buckles 618 on the second elastic arm 613 and the third elastic arm 615, and the buckles 618 extend in a direction close to the bracket side wall 21 and elastically abut against it, so that the second elastic arm 613 and the third elastic arm 615 are in interference fit with the two bracket side walls 21 through the two buckles 618, so as to increase the connection strength between the second elastic arm 613, the third elastic arm 615 and the two bracket side walls 21.

[0100] Specifically, when the second elastic arm 613 and the third elastic arm 615 are inserted between the two bracket side walls 21, the two clips 618 are tilted inward and elastically abut against the bracket side walls 21. Since the contact area between the two clips 618 and the two bracket side walls 21 is small, it is convenient to insert the second elastic arm 613 and the third elastic arm 615 between the two bracket side walls 21. After the second elastic arm 613 and the third elastic arm 615 are inserted into the two bracket side walls 21, the two clips 618 can also clamp the second elastic arm 613 and the third elastic arm 615 between the two bracket side walls 21.

[0101] In other embodiments, Figures 10-11 As shown, the end of the buckle 618 is embedded in the slide groove 22 so that the buckle 618 cooperates with the slide groove 22 to embed the second elastic arm 613 and the third elastic arm 615 between the two bracket side walls 21.

[0102] The buckle 618 can be installed on one end of the second elastic arm 613 and the third elastic arm 615 close to the second connecting arm 614 so that the buckle 618 can be embedded in the slide groove 22.

[0103] Specifically, after the end of the buckle 618 slides to correspond to the slide groove 22, the end of the buckle 618 enters the slide groove 22 under the action of its own elasticity to limit the second elastic arm 613 and the third elastic arm 615 from moving out from between the two bracket side walls 21.

[0104] The strength of the second elastic arm 613 and the third elastic arm 615 embedded in the two bracket side walls 21 can be adjusted by adjusting the direction of the end of the buckle 618. For example, when the end of the buckle 618 is tilted in the dissociation direction, the end of the buckle 618 is embedded in the slide groove 22 and abuts against the side wall of the slide groove 22, so that after the buckle 618 is embedded in the slide groove 22, it is difficult to pull the buckle 618 out of the slide groove 22, and the second elastic arm 613 and the third elastic arm 615 can be more firmly embedded between the two bracket side walls 21.

[0105] Furthermore, the fourth elastic arm 617 extends from a position away from the bracket side wall 21 to a position close to the bracket side wall 21, pressing the support portion against the bracket side wall 21, and the support top 62 includes a support plane 621 and a resistance slope 622. The support plane 621 is arranged at an end of the support top 62 away from the pre-installation portion 61, and is used to support the button side wall 51; the resistance slope 622 extends from the end of the support plane 621 close to the bracket side wall 21 to a direction away from the bracket side wall 21 and the support plane 621, so as to avoid the support plane 621 being embedded in the opposite wall of the bracket 20.

[0106] The supporting plane 621 is used to increase the supporting area of ​​the supporting top 62 against the button side wall 51 when the supporting top 62 is located outside the end of the button side wall 51. The resistance slope 622 is used to support and buckle on the bracket side wall 21 or the button side wall 51 to play a buffering role to prevent the supporting plane 621 from being embedded in the bracket side wall 21 or the button side wall 51 under the action of long-term bias.

[0107] For example, the supporting plane 621 and the resistance inclined surface 622 can be set as a V-shaped structure as a whole, and the closed end thereof is set as an arc-shaped transition.

[0108] Furthermore, the shell 10 is provided with a first dissociation hole 11 and a second dissociation hole 12, and the support top 62 is arranged corresponding to at least a part of the slide groove 22; the first dissociation hole 11 is configured for the dissociation tool to be inserted and pass through the slide groove 22 to push the support top 62 to move away from the bracket side wall 21, and the second dissociation hole 12 is configured for the dissociation tool to push the button 50 to drive the locking pin 40 to move to the locking position.

[0109] The first dissociation hole 11 and the second dissociation hole 12 are used to dissociate the latch 30 with a special tool.

[0110] Specifically, when the locking pin 40 moves to the locking position and engages with the latch 30, if the locking pin 40 is to be disengaged, a first disengagement tool is inserted into the first disengagement hole 11, and the support top 62 is pushed through the two slide grooves 22 to separate the support top 62 from the outer wall of the bracket side wall 21. Then, a second disengagement tool is inserted into the second disengagement hole 12 to push the button connecting wall 53, so that the button side wall 51 drives the locking pin 40 to move to the disengagement position, and when the locking pin 40 moves to the disengagement position, the latch 30 is disengaged from the locking pin 40, and at this time, the button side wall 51 is between the support top 62 and the bracket side wall 21.

[0111] like Fig.12 As shown, the seat belt connector also includes a retaining frame 70, a slider spring 80 and a slider 90; the retaining frame 70 is clamped to the end of the two bracket side walls 21 away from the latch 30; the slider spring 80 is arranged between the two bracket side walls 21, and one end of the slider spring 80 is connected to the retaining frame 70; the slider 90 is arranged between the two bracket side walls 21 and connected to the other end of the slider spring 80, and the end of the slider 90 away from the slider spring 80 is oppositely provided with two protrusions 91; when the slider 90 is not acted upon by the inserted latch 30 When the slider 90 is engaged, the slider spring 80 and the two protrusions 91 are used to support and limit the locking pin 40 in the locked position, and the supporting top 62 is pressed against the side surface of the button side wall 51; when the slider 90 is acted upon by the latch 30, the slider 90 compresses the slider spring 80, so that the slider 90 releases the limit on the locking pin 40, so that the locking pin 40 can move to the disengaged position, and the supporting top 62 is pressed against one side of the bracket side wall 21 and opposite to the outer side of the end of the button side wall 51.

[0112] Specifically, at least one bracket side wall 21 extends two clamping parts in the vertical direction, and the ends of the two clamping parts are provided with clamping pieces. Both ends of the retaining frame 70 are provided with clamping grooves corresponding to the clamping pieces, and the retaining frame 70 can be clamped with the clamping pieces through the clamping grooves to clamp the retaining frame 70 to the bracket side wall 21.

[0113] The clamping parts have a certain elasticity. When the two clamping parts are under pressure, the two clamping pieces can be close to each other, so that the clamping groove of the retaining frame 70 can be clamped on the two clamping pieces of the two clamping parts.

[0114] Furthermore, a boss is provided on the retaining frame 70 , and the boss is used to limit the slider spring 80 to prevent the slider spring 80 from sliding sideways.

[0115] The slider 90 can slide up and down between the two bracket side walls 21 through the slide rails provided on the two bracket side walls 21 to prevent the slider 90 from deflecting or tilting, which makes it impossible to limit the locking pin 40, and can push the latch 30 to move outward when it is disengaged.

[0116] Furthermore, a protruding column is also provided at one end of the slider 90 connected to the slider spring 80 to limit the slider spring 80 .

[0117] Among them, in the initial state of the seat belt connector, the locking pin 40 is in the disengaged position, and the slider 90 clamps the locking pin 40 under the support of the slider spring 80 and the retaining frame 70, preventing the locking pin 40 from moving to the locked position under the action of the button 50 and the button spring 52 in the initial state.

[0118] The slider 90 of this embodiment is used to limit and support the locking pin 40 when the locking pin 40 moves to the locking position, and can limit the locking pin 40 through two protrusions 91 on the slider 90 to prevent the locking pin 40 from moving in the disengagement direction, so as to further limit the locking pin 40.

[0119] The working principle of this embodiment is as follows:

[0120] When the latch 30 is not inserted between the two bracket side walls 21, the locking pin 40 is in the disengaged position, and the slider 90 is pushed by the retaining frame 70 and the slider spring 80 to the initial position close to the insertion buckle of the housing 10, and the limiting protrusion on the slider 90 is engaged with the locking pin 40 to prevent the button 50 and the locking pin 40 from moving in the engagement direction under the action of the button spring 52 (preventing the locking pin 40 from moving to the locked position), and at this time, the supporting top 62 of the anti-disengagement spring 60 is pressed against the outer side of the end of the button side wall 51;

[0121] When the latch 30 is inserted between the two bracket side walls 21, the latch 30 presses the slider 90 so that the slider spring 80 is compressed downward, and the resilience of the button spring 52 drives the button 50 and the locking pin 40 to move from the disengaged position to the locked position, so that the locking pin 40 can be engaged with the latch 30. At this time, the supporting top 62 of the anti-disengagement spring 60 is pressed against the outer wall of the bracket side wall 21 and against the end of the button side wall 51 to prevent the button 50 from moving in the disengagement direction.

[0122] After the latch 30 is inserted between the two bracket side walls 21, the slider spring 80 is compressed and moves downward, and the resilience of the button spring 52 drives the button 50 and the locking pin 40 to move in the engagement direction, and causes the locking pin 40 to move to the locking position to engage with the latch 30. The locking pin 40 locks the notch of the latch 30 as known. At this time, the support top 62 of the anti-disengagement spring 60 is pressed against the surface of the bracket side wall 21 and against the end of the button side wall 51 to prevent the button 50 from moving in the disengagement direction.

[0129] The flat surface portion 623 is used to prevent the support top portion 62 from damaging the support side wall 21 or embedding the support top portion 62 into the support side wall 21 when the support top portion 62 abuts against the support side wall 21 .

[0130] Specifically, the flange 624 is used to increase the support capacity of the button side wall 51 and prevent the support top 62 from being embedded in the bracket side wall 21 .

[0131] In some of the embodiments, the seat belt connector further includes a pressure plate, on which a slot corresponding to the connecting rib 24 is provided. After the slot is sleeved on the connecting rib 24 , the pressure plate is pressed on the pre-installed portion 61 .
