In some embodiments, the first fastening portion 21 includes a first fastening end 211 and a first limiting step 212, and the first fastening end 211 is further away from the second fastening portion 22 than the first limiting step 212, and a first limiting groove 213 is formed between the first fastening end 211 and the first limiting step 212. That is, in the first direction, the first snap end 211, the first limiting groove 213, and the first limiting step 212 are sequentially arranged.

In particular, when the outer circumferential surface of the first fastening end 211 is formed with the first conical surface 214, and the radius of the first conical surface 214 gradually decreases along the first direction towards the direction away from the first limiting step 212, that is, the radius of the end of the first fastening end 211 away from the first limiting step 212 is smaller than the radius of the end of the first fastening end 211 close to the first limiting step 212, so that the first fastening end 211 is conveniently inserted into the first mounting hole along the first direction towards the back plate 1.

That is, with continued reference to fig. 11, the first snap end 211 has a large end and a small end, the small end is disposed away from the first limiting step 212, and the large end is disposed close to the first limiting step 212.

In particular, when the shape of the first limiting groove 213 is a cylinder, the radius of the cross section of the first limiting groove 213 is smaller than the radius of the large end of the first fastening end 211, so that after the first fastening end 211 passes through the first mounting hole, the first fastening end 211 can be abutted against the second plate surface 12 of the back plate 1 along the opposite direction of the passing direction, thereby realizing the abutting limiting. Specifically, the first mounting hole is a circular hole, and the radius of the first mounting hole is smaller than the radius of the large end of the first snap end 211.

Meanwhile, the first limiting step 212 can be abutted on the bottom wall of the mounting groove 13 along the passing direction of the first clamping end 211, so that the backboard 1 is limited between the first limiting step 212 and the first clamping end 211, namely, the backboard 1 is limited in the first limiting groove 213, namely, the bottom wall of the mounting groove 13 is limited in the first limiting groove 213.

It should be noted that, in some embodiments, the radius of the first mounting hole is smaller than the radius of the large end of the first fastening end 211, so that there is a larger stress during the mounting process of the first fastening end 211, which causes inconvenience in mounting.

In the present disclosure, a plurality of first deformation gaps 215 are formed on the first snap end 211, the plurality of first deformation gaps 215 are arranged along the circumferential direction of the first snap end 211 at intervals, and the plurality of first deformation gaps 215 divide the first snap end 211 into a plurality of movable ends, so that the first snap end 211 can elastically deform along the radial direction of the first mounting hole in the mounting extrusion process, thereby reducing the mounting difficulty.

Referring to fig. 11, the first deformation gap 215 is provided to extend in the first direction, and in particular, the first deformation gap 215 may extend to the first limiting step 212 to increase the amount of deformation, so that the installation operation is simple. Of course, the extension length of the first deformation gap 215 may be specifically set as required, which is not limited in the present disclosure, so long as the first snap end 211 can be elastically deformed in the radial direction of the first mounting hole.

In some embodiments, a movable gap along the first direction is formed between the first fastening portion 21 and the first mounting hole, that is, the fit between the first fastening portion 21 and the first mounting hole on the back plate 1 is a clearance fit, so that the first fastening portion 21 has a movable space along the first direction, so that the second fastening portion 22 and the connector 3 are driven to have a movable space along the first direction.

So set up, the lamp strip that is connected with connector 3 is heated after the inflation, can drive connector 3 and remove in the activity space to avoid because hard connection makes the problem that expansion stress can't release, improve display device's life.

Specifically, the height of the first limiting groove 213 in the first direction is greater than the thickness of the groove bottom wall of the mounting groove 13, so that a movable gap in the first direction is formed between the first fastening portion 21 and the first mounting hole. It should be noted that, the difference between the height of the first limiting groove 213 along the first direction and the thickness of the bottom wall of the mounting groove 13 is not too large, and it is required to ensure that the connector 3 and the light bar do not have too much active space on the back plate 1, so as to ensure the screen lighting effect and improve the user experience.

In some embodiments, the diameter of the first mounting hole is greater than the width of the first limiting groove 213 in the radial direction of the first mounting hole, such that the first snap portion 21 is clearance fit with the first mounting hole in the radial direction of the first mounting hole. That is, there is a moving gap between the first limiting groove 213 and the first mounting hole in the radial direction of the first mounting hole, so that the connector 3 has a moving space in the radial direction of the first mounting hole.

It can be understood that the light bar is fixed on the back plate 1 by hard connection modes such as screw fixation, and the connector 3 has a movable space in the radial direction of the first mounting hole, so that the problem of poor matching between the connector 3 and the light bar caused by the deviation of the light bar and the connector 3 during mounting is avoided, and the light bar mounting device has high fault tolerance and good reliability.

It should be noted that, the difference between the diameter of the first mounting hole and the width of the first limiting groove 213 along the radial direction of the first mounting hole is not too large, that is, it is required to ensure that the connector 3 and the light bar do not have too much active space on the back plate 1, so as to ensure the screen lighting effect and improve the user experience.

That is, in the first direction, the second snap end 221, the second limiting groove 223, and the second limiting step 222 are sequentially arranged.

It will be appreciated that, referring to fig. 11, in the first direction, the first snap end 211, the first limiting groove 213, the first limiting step 212, the second limiting step 222, the second limiting groove 223, and the second snap end 221 are sequentially arranged.

In particular, when the outer circumferential surface of the second snap end 221 is formed with the second conical surface 224, and the radius of the second conical surface 224 gradually decreases along the first direction towards the direction away from the second limiting step 222, that is, the radius of the end of the second snap end 221 away from the second limiting step 222 is smaller than the radius of the end of the second snap end 221 close to the second limiting step 222, so that the second snap end 221 is conveniently inserted into the second mounting hole along the first direction towards the connector 3.

That is, with continued reference to fig. 11, the second snap end 221 has a large end and a small end, the small end is disposed away from the second limiting step 222, and the large end is disposed close to the second limiting step 222.

In particular, when the shape of the second limiting groove 223 is a cylinder, the radius of the cross section of the second limiting groove 223 is smaller than the radius of the large end of the second snap end 221, so that after the second snap end 221 passes through the second mounting hole, the second snap end 221 along the opposite direction of the passing direction can be abutted against the side surface of the connector 3 far away from the backboard 1, thereby realizing the abutting limiting. Specifically, the second mounting hole is a circular hole, and the radius of the second mounting hole is smaller than the radius of the large end of the second snap end 221.

Meanwhile, the second limiting step 222 can abut against a surface of the connector 3 facing the back plate 1 along the passing direction of the second snap end 221, so that the connector 3 is limited between the second limiting step 222 and the second snap end 221, i.e. the connector 3 is limited in the second limiting groove 223.

It should be noted that, in some embodiments, the radius of the second mounting hole is smaller than the radius of the large end of the second fastening end 221, so that there is a larger stress during the mounting process of the second fastening end 221, which causes inconvenience in mounting.

In the present disclosure, a plurality of second deformation gaps 225 are formed on the second snap end 221, the plurality of second deformation gaps 225 are disposed along the circumferential direction of the second snap end 221 at intervals, and the plurality of second deformation gaps 225 divide the second snap end 221 into a plurality of movable ends, so that the second snap end 221 can elastically deform along the radial direction of the second mounting hole in the mounting extrusion process, thereby reducing the mounting difficulty.

Referring to fig. 11, the second deformation gap 225 is provided to extend in the first direction, and in particular, the second deformation gap 225 may extend to the second limiting step 222 to increase the amount of deformation, so that the installation operation is simple. Of course, the extension length of the second deformation gap 225 may be specifically set as needed, which is not limited in the present disclosure, so long as the second snap end 221 can be elastically deformed in the radial direction of the second mounting hole.

In some embodiments, a movable gap is formed between the second fastening portion 22 and the second mounting hole along the first direction, that is, the fit between the second fastening portion 22 and the second mounting hole on the back plate 1 is a clearance fit, so that the second fastening portion 22 has a movable space along the first direction, so as to drive the connector 3 to form a movable space along the first direction.

So set up, the lamp strip that is connected with connector 3 is heated after the inflation, can drive connector 3 and remove in the activity space to avoid because hard connection makes the problem that expansion stress can't release, improve display device's life.

Specifically, the height of the second limiting groove 223 in the first direction is greater than the thickness of the connector 3, so that a movable gap in the first direction is formed between the first fastening portion 21 and the first mounting hole. It should be noted that, the difference between the height of the second limiting groove 223 along the first direction and the thickness of the connector 3 is not too large, so that the connector 3 and the light bar do not have too much active space on the back plate 1, thereby ensuring the screen lighting effect and improving the user experience.

In some embodiments, the diameter of the second mounting hole is greater than the width of the second limiting groove 223 in the radial direction of the second mounting hole, such that the second snap portion 22 is clearance fit with the second mounting hole in the radial direction of the second mounting hole. That is, there is a movable gap between the second limiting groove 223 and the second mounting hole in the radial direction of the second mounting hole, so that the connector 3 has a movable space in the radial direction of the second mounting hole.

It can be understood that the light bar is fixed on the back plate 1 by hard connection modes such as screw fixation, and the connector 3 has a movable space in the radial direction of the second mounting hole, so that the problem of poor matching between the connector 3 and the light bar caused by the deviation of the light bar and the connector 3 during mounting is avoided, and the light bar mounting device has high fault tolerance and good reliability.

It should be noted that, the difference between the diameter of the second mounting hole and the radial width of the second limiting groove 223 along the second mounting hole is not too large, that is, it is required to ensure that the connector 3 and the light bar cannot have too much active space on the back plate 1, so as to ensure the screen lighting effect and improve the user experience.

In particular, when the shape of the third limiting groove 43 is a cylinder, the radius of the cross section of the third limiting groove 43 is smaller than the radius of the large end of the third fastening end 41, so that after the third fastening end 41 passes through the fourth mounting hole and the third mounting hole, the third fastening end 41 can be abutted against the side surface, away from the connector 3, of the back plate 1 along the opposite direction of the passing direction, and thus the abutting limiting is realized.

Specifically, the fourth mounting hole and the third mounting hole are circular holes, and the radii of the fourth mounting hole and the third mounting hole are the same and are smaller than the radius of the large end of the third snap end 41.

Meanwhile, the third limiting step 42 can abut against the side surface, far away from the back plate 1, of the connector 3 along the passing direction of the third snap end 41, so that the connector 3 and the back plate 1 are limited between the third limiting step 42 and the third snap end 41, namely, the connector 3 and the back plate 1 are limited in the third limiting groove 43. That is, the connector 3 and the back plate 1 are fitted and commonly retained in the third retaining groove 43.

It should be noted that, in some embodiments, the radius of the fourth mounting hole and the third mounting hole is smaller than the radius of the large end of the third fastening end 41, so that there is a large stress during the mounting process of the third fastening end 41, which causes inconvenience in mounting.

In the present disclosure, a plurality of third deformation gaps are formed on the third fastening end 41, the plurality of third deformation gaps are arranged along the circumferential direction of the third fastening end 41 at intervals, and the plurality of third deformation gaps divide the third fastening end 41 into a plurality of movable ends, so that the third fastening end 41 can be elastically deformed in the radial direction of the fourth mounting hole and the second mounting hole in the mounting extrusion process, thereby reducing the mounting difficulty.

Referring to fig. 7, the third deformation gap is provided to extend in the first direction, and in particular, the extension length of the third deformation gap may be provided as needed, which is not limited by the present disclosure, so long as the third snap end 41 can be elastically deformed in the radial direction of the third mounting hole.

The number and the mounting position of the second fastening members 4 are not particularly limited, as long as the connector 3 and the back plate 1 can be fixed.

In some embodiments, the engagement between the second fastening member 4 and the back plate 1 and the connector 3 may also be set in a clearance fit manner along the first direction, specifically, a clearance between the second fastening member 4 and the fourth mounting hole and the third mounting hole is formed along the first direction, so that after the connector 3 is assembled with the back plate 1, there is a clearance space along the first direction.

So, after the lamp strip that is connected with connector 3 is heated and expands, can drive connector 3 and remove in the activity space to avoid because hard connection makes the unable problem of releasing of expansion stress, and then avoid connector 3 and lamp strip to damage because of the unable release of expansion stress, improve display device's life.

Specifically, the height of the third limiting groove 43 along the first direction is greater than the common thickness of the connector 3 and the back plate 1, so that a movable gap along the first direction is formed between the second fastening member 4 and the fourth mounting hole and between the second fastening member and the third mounting hole.

Further, the diameters of the fourth mounting hole and the third mounting hole are larger than the radial width of the third limiting groove 43 along the fourth mounting hole or the third mounting hole, so that the second fastening piece 4 is in clearance fit with the fourth mounting hole and the third mounting hole in the radial direction of the fourth mounting hole or the third mounting hole.

That is, there is a movable gap between the third limiting groove 43 and the fourth mounting hole or the third mounting hole in the radial direction of the fourth mounting hole or the third mounting hole, so that the connector 3 has a movable space in the radial direction of the fourth mounting hole or the third mounting hole. The problem of poor matching between the connector 3 and the light bar caused by deviation of the light bar and the connector 3 during installation can be avoided, and the fault tolerance is high and the reliability is good.

Of course, it should be noted that the first fastening end 211 of the first fastening portion 21, the second fastening end 221 of the second fastening portion 22, and the third fastening end 41 of the second fastening portion 4 of the present disclosure are not limited to forming a conical outer circumferential surface, as long as they can correspondingly pass through the corresponding first mounting hole, second mounting hole, third mounting hole, or fourth mounting hole and fixedly connect the back plate 1 and the connector 3 together, which is not limited in this disclosure.
