Detailed Description

Hereinafter, specific embodiments of the present application will be described in detail with reference to the accompanying drawings.

The application provides an electronic equipment, the BTB connector receives horizontal effort, is transversely locked in order to realize locking, improves electronic equipment's reliability.

The electronic device to which the technical solution of the present application can be applied includes, but is not limited to, any device with a BTB connector, such as a mobile phone, a headset, a tablet computer, a desktop computer, and a television.

For convenience of description, the following description will be given taking an electronic device as a mobile phone as an example, and the electronic device of the present application will be described below with specific embodiments.

Referring to fig. 1, a mobile phone 1 according to an embodiment of the present disclosure includes a screen 1a, a middle frame 10 and a battery cover 1b, wherein the screen 1a and the battery cover 1b are respectively mounted on two opposite sides of the middle frame 10 along a thickness direction (shown as a Z direction in fig. 1) of the mobile phone 1. In the embodiment of the present application, the middle frame 10, the screen 1a, and the battery cover 1b may be attached together using an adhesive substance (for example, foam cotton), but the connection manner of the middle frame 10, the screen 1a, and the battery cover 1b is not limited to the adhesive substance as long as the assembly can be achieved.

In some possible embodiments, referring to fig. 2, the middle frame 10 of the handset 1 is provided with a BTB connector 20. Referring to fig. 3, the middle frame 10 includes a middle frame body 11 and a mounting groove 111 provided in the middle frame body 11, and the BTB connector 20 is provided in the mounting groove 111 of the middle frame 10.

Fig. 4 is a schematic structural diagram of a BTB connector 20 according to an embodiment of the present invention. The BTB connector 20 is used to connect a first device (e.g., a PCB board, not shown) with a second device (e.g., an FPC, not shown). Devices connected to the BTB connector are called panel devices such as the above-mentioned PCB board and FPC. The BTB connector 20 includes a first plug assembly 21 (also referred to as a male connector) and a second plug assembly 22 (also referred to as a female connector) that are mated with each other. Fig. 4 shows that the first plug assembly 21 is provided with a cable 211, the first plug assembly 21 is connected to the first component by the cable 211, and the second plug assembly 22 is connected to the second component by soldering or by the cable 211.

Illustratively, the first plug assembly 21 is provided with protruding pins (not shown), the second plug assembly 22 is provided with hole-shaped pins (not shown), and the protruding pins of the first plug assembly 21 and the hole-shaped pins of the second plug assembly 22 are in one-to-one correspondence. The protruded pins on the first plug assembly 21 are inserted into the hole-shaped pins on the second plug assembly 22, so that the first plug assembly 21 and the second plug assembly 22 are buckled, and the connection between the first device and the second device is realized. That is to say, the two plug-in modules are respectively connected to the two panels, and then the two plug-in modules are buckled, so that the lines to be connected in the two panels can be connected.

In some possible embodiments, referring to fig. 5, after the BTB connector 20 is placed in the mounting groove 111 of the middle frame 10 along the longitudinal direction (shown in the Z direction in fig. 5), the BTB connector 20 is spaced apart from the groove wall of the mounting groove 111 along the transverse direction (shown in the X direction in fig. 5 or shown in the Y direction in fig. 3) (i.e., there is a transverse gap), which is perpendicular to the longitudinal direction. For example, as shown in fig. 5, the second plug module 22 of the BTB connector 20 is spaced apart from a groove wall 1111 of one lateral side of the mounting groove 111, and the first plug module 21 of the BTB connector 20 is spaced apart from a groove wall 1112 of the other lateral side of the mounting groove 111.

The BTB connector 20 is not locked in the mounting groove 111 due to the lateral clearance of the BTB connector 20 from the wall of the mounting groove 111. For example, referring to fig. 6a, the first plug assembly 21 and the second plug assembly 22 of the BTB connector 20 may be buckled or not tightly, and thus the first plug assembly 21 and the second plug assembly 22 of the BTB connector 20 may be separated (the X direction in fig. 6a shows the separation direction). For another example, referring to fig. 6b, the BTB connector 20 may be released from the mounting groove 111 of the middle frame 10, that is, the BTB connector 20 may be separated from the mounting groove 111 of the middle frame 10 (the direction a in fig. 6b shows the separation direction). These situations all cause the reduction of the mounting reliability of the BTB connector 20, which may cause the connection of the panel device inside the cellular phone 1 to fail.

Therefore, the transverse clamping structure is arranged in the middle frame 10 of the mobile phone 1, so that the transverse clamping of the BTB connector 20 is realized, and the assembling stability and the anti-loosening performance of the BTB are effectively improved.

Referring to fig. 7 and 8, a clamping structure 30 is provided in a mounting groove 111 of the middle frame 10 of the cellular phone 1, the BTB connector 20 is mounted in the mounting groove 111, and the clamping structure 30 laterally clamps the BTB connector 20 in a groove of the mounting groove 111. The lateral direction (shown by the X direction in fig. 8) intersects with the depth direction (shown by the Z direction in fig. 8) of the mounting groove 111. Illustratively, the transverse direction is perpendicular to the depth direction of the mounting groove 111. In some possible embodiments, the angle between the transverse direction and the depth direction of the mounting groove 111 is acute or obtuse.

Therefore, the clamping structure 30 is used for transversely clamping the BTB connector 20 to play a role in preventing looseness, the clamping structure 30 is used for effectively improving the assembling stability and the looseness-preventing performance of the BTB connector 20, and the connection reliability of a panel device inside the mobile phone 1 is ensured.

The specific structure of the clamping structure 30 will be described in detail below with reference to the accompanying drawings.

In some possible embodiments, with reference to fig. 8, the clamping structure 30 comprises: a transverse support plate 31, a first clamping arm 32 and a second clamping arm 33. Wherein the lateral support plate 31 extends in the lateral direction (shown in the X-direction in fig. 8). Illustratively, the lateral support plate 31 is disposed facing the bottom wall of the mounting groove 111. Illustratively, the lateral support plate 31 is attached to the bottom wall of the mounting groove 111. Illustratively, both lateral ends of the bottom wall of the mounting groove 111 are perpendicular to a groove wall 1111 on one lateral side and a groove wall 1112 on the other lateral side of the mounting groove 111, respectively. The first clamp arm 32 and the second clamp arm 33 extend in the longitudinal direction (shown in the Z direction in fig. 8), and both ends in the lateral direction of the lateral support plate 31 are connected to one end 32a in the longitudinal direction of the first clamp arm 32 and one end 33a in the longitudinal direction of the second clamp arm 33, respectively, and the BTB connector 20 is adapted to be clamped between the first clamp arm 32 and the second clamp arm 33. Illustratively, in the transverse direction, the other longitudinal end 32b of the first clamping arm 32 abuts against a groove wall 1111 on one transverse side of the mounting groove 111, and the other longitudinal end 33b of the second clamping arm 33 abuts against a groove wall 1112 on the other transverse side of the mounting groove 111.

When the BTB connector 20 is mounted in the mounting groove 111, the first clamping arm 32 and the second clamping arm 33 together clamp the BTB connector 20, and at the same time, since the longitudinal other end 32b of the first clamping arm 32 abuts against the groove wall 1111 of one lateral side of the mounting groove 111 and the longitudinal other end 33b of the second clamping arm 33 abuts against the groove wall 1112 of the other lateral side of the mounting groove 111, the lateral movement of the BTB connector 20 is restricted. Therefore, the first clamping arm 32 and the second clamping arm 33 can transversely clamp the BTB connector 20 in the groove of the mounting groove 111, so that the anti-loosening effect is achieved, and the assembling stability and the anti-loosening performance of the BTB are effectively improved.

Exemplarily, the middle portion of the first clamping arm 32 comprises a first lateral clamping portion protruding towards the second clamping arm 33, the middle portion of the second clamping arm 33 comprises a second lateral clamping portion protruding towards the first clamping arm 32, and the BTB connector 20 is adapted to be clamped between said first lateral clamping portion and said second lateral clamping portion. That is, the first and second lateral clamping portions together laterally clamp the BTB connector 20. The first lateral clamp portion is, for example, a third portion 323 of the first clamp arm 32, which will be described later, and the second lateral clamp portion is, for example, a third portion 333 of the second clamp arm 33, which will be described later. That is, the clamping structure 30 laterally clamps the BTB connector 20 by the first and second lateral clamping portions.

In assembling the BTB connector 20, the BTB connector 20 may be first fitted into the clamping structure 30, and then the BTB connector 20 and the clamping structure 30 are fitted into the mounting groove 111 together, or the clamping structure 30 may be first fitted into the mounting groove 111, and then the BTB connector 20 is fitted into the clamp mounting groove 111 and the clamping structure 30.

Illustratively, the clamping structure 30 of the embodiment of the present application exists in two states: an expanded state and a contracted state. Referring to fig. 9a and 9b, fig. 9a illustrates a perspective view of the clamping structure 30 in an unfolded state, and fig. 9b illustrates a side view of the clamping structure 30 in an unfolded state, the clamping structure 30 of the embodiment of the present application being in an unfolded state before being installed in the installation groove 111. Referring to fig. 9c and 9d, fig. 9c shows a perspective view of the clamping structure 30 in a contracted state, and fig. 9d shows a side view of the clamping structure 30 in a contracted state, the clamping structure 30 of the embodiment of the present application being in a contracted state after being mounted in the mounting groove 111.

Illustratively, one longitudinal end 32a of the first clamp arm 32 is integrally formed and elastically connected to one lateral end 31a of the lateral support plate 31, and one longitudinal end 33a of the second clamp arm 33 is integrally formed and elastically connected to the other lateral end 31b of the lateral support plate 31. Equivalently, the first clamping arm 32, the second clamping arm 33 and the transverse support plate 31 are integrally formed, and the first clamping arm 32 and the second clamping arm 33 are respectively elastically connected with the transverse support plate 31.

Exemplary materials of the clamping structure 30 include metal materials and non-metal materials (e.g., industrial plastics), which can be elastically deformed without breaking.

Referring to fig. 9a and 9b, before the clamping structure 30 is installed in the installation groove 111 (the clamping structure 30 is in the unfolded state), an extension line of one longitudinal end 32a of the first clamping arm 32 and an extension line of one transverse end 31a of the transverse support plate 31 have a first included angle (shown as a in fig. 9 b), an extension line of one longitudinal end 33a of the second clamping arm 33 and the other transverse end 31b of the transverse support plate 31 have a second included angle (shown as b in fig. 9 b), and the other longitudinal end 32b of the first clamping arm 32 and the other longitudinal end 33b of the second clamping arm 33 can move towards each other in the transverse direction under the action of external force, so that the clamping structure 30 can be switched from the unfolded state to the folded state. Illustratively, the first included angle and the second included angle are obtuse angles, such as 100 °, 120 °, 130 °, and the like. Illustratively, the first included angle and the second included angle are equal. That is, the first and second clamping

arms

32 and 33 form a large opening when the clamping structure 30 is in the unfolded state before being installed in the installation groove 111.

Referring to fig. 8 and 9d, during the process of installing the clamping structure 30 in the installation slot 111, the first clamping arm 32 and the second clamping arm 33 of the clamping structure 30 are subjected to a transverse force (indicated by F in fig. 9 d), and move towards each other in the transverse direction under the action of the transverse force, so that the clamping structure 30 is switched from the expanded state to the contracted state, and the first clamping arm 32 and the second clamping arm 33 form a small opening.

As shown in fig. 8, after the clamping structure 30 is completely installed in the installation slot 111 (the clamping structure 30 is in a contracted state), the other longitudinal end 32b of the first clamping arm 32 elastically abuts against the slot wall 1111 on one lateral side of the installation slot 111, the other longitudinal end 33b of the second clamping arm 33 elastically abuts against the slot wall 1112 on the other lateral side of the installation slot 111, an extension line of the one longitudinal end 32a of the first clamping arm 32 and an extension line of the one lateral end 31a of the lateral support plate 31 have a third included angle (shown by c in fig. 9 d), the third included angle is smaller than the first included angle, an extension line of the one longitudinal end 33a of the second clamping arm 33 and an extension line of the other lateral end 31b of the lateral support plate 31 have a fourth included angle (shown by d in fig. 9 d), and the fourth included angle is smaller than the second included angle. Illustratively, the third angle and the fourth angle are each right angles. Illustratively, the first included angle and the second included angle are equal.

Elastic force is generated between the clamping structure 30 and the mounting groove 111 of the middle frame 10, and the BTB connector 20 is transversely and elastically clamped in the groove of the mounting groove 111, so that the anti-loosening effect can be effectively achieved.

With continued reference to fig. 8 and 9b, in some possible embodiments, the first and second clamping

arms

32, 33 are multi-segmented, bent plate-like structures. Wherein the first clamping arm 32 comprises a first portion 321, a second portion 322, a third portion 323, a fourth portion 324 and a fifth portion 325 which are connected in sequence, and the second clamping arm 33 comprises a first portion 331, a second portion 332, a third portion 333, a fourth portion 334 and a fifth portion 335 which are connected in sequence. The first portion 321 of the first clamp arm 32 is connected to one lateral end 31a of the lateral support plate 31, and the first portion 331 of the second clamp arm 33 is connected to the other lateral end 31b of the lateral support plate 31; the fifth portion 325 of the first clamping arm 32 abuts a channel wall 1111 on one lateral side of the mounting slot 111, and the fifth portion 335 of the second clamping arm 33 abuts a channel wall 1112 on the other lateral side of the mounting slot 111. The third portion 323 of the first clamping arm 32 comprises the first lateral clamping portion of the first clamping arm 32 and the third portion 333 of the second clamping arm 33 comprises the second lateral clamping portion of the second clamping arm 33. That is, the third portion 323 of the first clamping arm 32 and the third portion 333 of the second clamping arm 33 together laterally clamp the BTB connector 20.

With continued reference to fig. 9b, in some possible embodiments, the angle between the first portion 321 and the second portion 322 of the first clamping arm 32 (shown as α in fig. 9 b) is equal to the angle between the second portion 322 and the third portion 323 of the first clamping arm 32 (shown as α in fig. 9 b), and the angle between the third portion 323 and the fourth portion 324 of the first clamping arm 32 (shown as β in fig. 9 b) is equal to the angle between the fourth portion 324 and the fifth portion 325 of the first clamping arm 32 (shown as β in fig. 9 b). That is, the first portion 321 of the first clamp arm 32 is parallel to the third portion 323 of the first clamp arm 32, and the third portion 323 of the first clamp arm 32 is parallel to the fifth portion 325 of the first clamp arm 32.

The angle between the first portion 331 and the second portion 332 of the second clamping arm 33 (shown as α in fig. 9 b) is equal to the angle between the second portion 332 and the third portion 333 of the second clamping arm 33 (shown as α in fig. 9 b), and the angle between the third portion 333 and the fourth portion 334 of the second clamping arm 33 (shown as β in fig. 9 b) is equal to the angle between the fourth portion 334 and the fifth portion 335 of the second clamping arm 33 (shown as β in fig. 9 b). That is, the first portion 331 of the second clamping arm 33 is parallel to the third portion 333 of the second clamping arm 33, and the third portion 333 of the second clamping arm 33 is parallel to the fifth portion 335 of the second clamping arm 33.

After the arrangement, when the clamping structure 30 is installed in the installation groove 111, the first clamping arm 32 and the second clamping arm 33 respectively laterally abut against the groove wall of the installation groove 111, the first clamping arm 32 and the second clamping arm 33 can be tightly attached to the groove wall of the installation groove 111 and can be tightly attached to the BTB connector 20, and the clamping effect of the clamping structure 30 on the BTB connector 20 is improved due to the fact that the first clamping arm 32 and the second clamping arm 33 are attached to the groove wall of the installation groove 111.

In some possible embodiments, the first and second clamping

arms

32 and 33 are straight-segment plate-like structures. That is, the five portions of the first clamping arm 32 are in the same plane and the five portions of the second clamping arm 33 are in the same plane.

Illustratively, referring to fig. 9b, the first and

second clamp arms

32 and 33 are symmetrically disposed along a central axis (indicated by L in fig. 9 b) perpendicular to the transverse support plate 31. That is, the first portion 321 of the first clamp arm 32 and the first portion 331 of the second clamp arm 33 are symmetrically disposed along a central axis perpendicular to the lateral support plate 31.

Second portions

322 and 332 of first and

second clamp arms

32 and 33 are symmetrically disposed along a central axis perpendicular to transverse support plate 31. The third portion 323 of the first clamp arm 32 and the third portion 333 of the second clamp arm 33 are symmetrically disposed along a central axis perpendicular to the transverse support plate 31. Fourth portion 324 of first clamping arm 32 and fourth portion 334 of second clamping arm 33 are symmetrically disposed about a central axis perpendicular to transverse support plate 31.

Fifth portions

325 and 335 of first and

second clamp arms

32 and 33 are symmetrically disposed about a central axis perpendicular to transverse support plate 31.

In some possible embodiments, referring to fig. 10, the first portion 321 and the fifth portion 325 of the first clamping arm 32 respectively abut against the lateral groove wall 1111 of the mounting groove 111 (when a lateral force is applied (shown as F in fig. 9 d)), and the third portion 323 of the first clamping arm 32 is spaced apart from the lateral groove wall 1111 of the mounting groove 111; the first and

fifth portions

331 and 335 of the second clamping arm 33 respectively engage with the groove wall 1112 on the other lateral side of the mounting groove 111 (subjected to a lateral force (shown by F in fig. 9 d)), and the third portion 333 of the second clamping arm 33 is spaced apart from the groove wall 1112 on the other lateral side of the mounting groove 111.

Equivalently, in the contracted state of the clamping structure 30, the first clamping arm 32 and the second clamping arm 33 are each laterally recessed in a direction toward the BTB connector 20. That is, the lateral distance between the third portion 323 of the first clamping arm 32 and the third portion 333 of the second clamping arm 33 is equal to the lateral dimension of the BTB connector 20, but less than the lateral distance between the remaining portions of the first clamping arm 32 and the second clamping arm 33.

Thus, on the one hand, the clamping structure 30 can provide a uniform transverse force to the BTB connector 20, so as to play a role in preventing looseness during the assembling process, and prevent the BTB connector 20 from tilting to generate wrong pins due to uneven stress. The term "wrong pin" means that the protruding pin on the male connector of the BTB connector 20 and the hole pin on the female connector are dislocated and cannot be aligned to realize the insertion. On the other hand, the clamping structure 30 can be adapted to different lateral dimensions of the BTB connector 20, and the lateral distance between the third portion 323 of the first clamping arm 32 and the third portion 333 of the second clamping arm 33 of the clamping structure 30 can be adapted according to different lateral dimensions of the BTB connector 20, that is, lateral clamping of different lateral dimensions of the BTB connector 20 can be realized.

In some possible embodiments, the third portion 323 of the first clamping arm 32 and the third portion 333 of the second clamping arm 33 are arranged parallel to each other in the contracted state of the clamping structure 30 (as shown in fig. 9 d), i.e. after the clamping structure 30 is mounted in the mounting groove 111. The BTB connector 20 is parallel to the third portion 323 of the first clamping arm 32 and the third portion 333 of the second clamping arm 33, so that the BTB connector 20 is evenly stressed in the transverse direction and has a good clamping effect.

In some possible embodiments, the first portion 321 of the first clamping arm 32 and the first portion 331 of the second clamping arm 33 are perpendicular to the transverse support plate 31, respectively, in the contracted state of the clamping structure 30 (as shown in fig. 9 d), i.e. after the clamping structure 30 is mounted in the mounting groove 111. Such that the first portion 321 of the first clamping arm 32 abuts the channel wall 1111 of one lateral side of the mounting slot 111 (as shown in fig. 10), and the first portion 331 of the second clamping arm 33 abuts the channel wall 1112 of the other lateral side of the mounting slot 111 (as shown in fig. 10) to better generate the lateral clamping force.

In some possible embodiments, referring to fig. 11a and 11b, fig. 11a and 11b provide another clamping structure 30. The clamping structure 30 shown in fig. 11a and 11b comprises a first clamping arm 32, a second clamping arm 33, a transverse support plate 31 and a spindle. The difference from the clamping structure 30 shown in fig. 9a to 9d is that one longitudinal end 32a of the first clamping arm 32 shown in fig. 11a and 11b is rotatably connected to one transverse end 31a of the transverse support plate 31 by a first rotating shaft 34, one longitudinal end 33a of the second clamping arm 33 shown in fig. 11a and 11b is rotatably connected to the other transverse end 31b of the transverse support plate 31 by a second rotating shaft 35, and the rest of the structure is the same.

That is, the first clamping arm 32, the second clamping arm 33 and the lateral support plate 31 in fig. 9a to 9d are integrally formed, whereas the first clamping arm 32, the second clamping arm 33 and the lateral support plate 31 in fig. 11a and 11b are not integrally formed but connected by a rotation shaft. Also, the clamping structure 30 in fig. 11a and 11b applies a lateral force by deforming the first and second clamping

arms

32 and 33 through the rotation shaft.

In some possible embodiments, referring to fig. 12a, fig. 12a shows a schematic structural view of the first rotating shaft 34, and the second rotating shaft 35 and the first rotating shaft 34 have the same structure. The embodiment of the present application takes the structure of the first rotating shaft 34 as an example, and the structure of the second rotating shaft 35 is described with reference to the structure of the first rotating shaft 34.

One end of the first clamping arm 32 is provided with a first limit positioning block 342. A groove is formed in the rotating shaft body 341 of the first rotating shaft 34, a separating block 343 is arranged in the groove, and the separating block 343 divides the groove into a first limiting clamping groove 3411 and a first additional limiting clamping groove 3412 along the circumferential direction. The first position-limiting clamping groove 3411 and the first additional position-limiting clamping groove 3412 are respectively matched with the first position-limiting positioning block 342.

Similarly, a second limit positioning block (having the same structure as the first limit positioning block 342) is disposed at one end of the second clamping arm 33. The rotating shaft body of the second rotating shaft 35 is provided with a groove (the structure of the groove is the same as that of the groove on the rotating shaft body 341 of the first rotating shaft 34), a separating block (the structure of the separating block 343 is the same as that of the first rotating shaft 34) is arranged in the groove, and the separating block circumferentially divides the groove into a second limiting clamping groove (the structure of the second limiting clamping groove is the same as that of the first limiting clamping groove 3411) and a second additional limiting clamping groove (the structure of the second additional limiting clamping groove is the same as that of the first additional limiting clamping groove 3412). The second limit clamping groove and the second additional limit clamping groove are respectively matched with the second limit positioning block.

Before the clamping structure 30 is installed in the mounting groove 111 (the clamping structure 30 is in an unfolded state, as shown in fig. 11 a), the first limit positioning block 342 is located in the first additional limit catch 3412, the first limit positioning block 342 is separated from the first limit catch 3411, the second limit positioning block is located in the second additional limit catch, the second limit positioning block is separated from the second limit catch, and the longitudinal other end 32b of the first clamping arm 32 and the longitudinal other end 33b of the second clamping arm 33 can move transversely toward each other under the action of an external force.

Referring to fig. 12b and 13, after the clamping structure 30 is installed in the mounting groove 111 (the clamping structure 30 is in a contracted state), the first limit positioning block 342 is separated from the first additional limit catch 3412 and is engaged with the first limit catch 3411 (as shown in fig. 12 b), and the second limit positioning block is separated from the second additional limit catch and is engaged with the second limit catch to limit the first clamping arm 32 and the second clamping arm 33 from moving in a lateral direction or in a reverse direction. That is, after the clamping structure 30 is installed in the installation groove 111, the first rotating shaft 34 limits the movement of the first clamping arm 32 in the circumferential direction (indicated by the direction T in fig. 12 a), and the second rotating shaft 35 limits the movement of the second clamping arm 33 in the circumferential direction. So that the BTB connector 20 can be smoothly placed between the first and

second clamp arms

32 and 33 and laterally clamped by the first and

second clamp arms

32 and 33.

In some possible embodiments, referring to fig. 14a, fig. 14a shows a schematic view of another clamping structure. The clamping structure shown in fig. 14a comprises: the stopper 36, the stopper 36 is elastically connected with a groove wall 1111 of one lateral side of the mounting groove 111 in a lateral direction (shown in an X direction in fig. 14 a) by a first elastic member 361 (e.g., a spring), and is disposed opposite to a groove wall 1112 of the other lateral side of the mounting groove 111 in the lateral direction. That is, the stopper 36 is disposed at a distance from the groove wall 1112 on the other lateral side of the mounting groove 111, and the BTB connector 20 is placed in this distance.

Referring to fig. 14b, after the BTB connector 20 is installed in the installation groove 111, the stop 36 and the groove wall 1112 on the other lateral side of the installation groove 111 clamp the BTB connector 20 laterally in the groove of the installation groove 111, and the BTB connector 20 is subjected to a lateral force by the elastic force of the first elastic member 361, thereby performing a lateral locking function.

In some possible embodiments, with reference to fig. 14a, the clamping structure 30 further comprises: the positioning block 37 is elastically connected to the bottom wall of the mounting groove 111 along a longitudinal direction (shown in a Z direction in fig. 14 a) by a second elastic member 371 (e.g., a spring), and the longitudinal direction and the transverse direction are crossed. Illustratively, the longitudinal direction is perpendicular to the transverse direction.

Referring to fig. 14a, before the BTB connector 20 is mounted in the mounting groove 111, the positioning block 37 laterally abuts against the stopper 36 to limit the movement of the stopper 36 laterally toward the groove wall 1112 on the other lateral side of the mounting groove 111, and the first elastic member 361 is in a compressed state.

Referring to fig. 14b, after the BTB connector 20 is mounted in the mounting groove 111, the positioning block 37 is pressed in the longitudinal direction to be received in the bottom wall of the mounting groove 111, and the stopper 36 and the groove wall 1112 on the other lateral side of the mounting groove 111 clamp the BTB connector 20 laterally in the groove of the mounting groove 111 under the elastic force of the first elastic member 361.

Referring to fig. 15a, fig. 15a shows another arrangement of positioning blocks 37. The positioning block 37 shown in fig. 15a has one end connected (e.g., rotatably connected) to the top end of the groove wall 1111 on one lateral side of the mounting groove 111, and the other end for limiting the movement of the stopper 36 toward the groove wall 1112 on the other lateral side of the mounting groove 111 in the lateral direction.

Referring to fig. 15a, before the BTB connector 20 is mounted in the mounting groove 111, the other end of the positioning block 37 is engaged with the top end of the stopper 36 far from the bottom wall of the mounting groove 111 to limit the movement of the stopper 36 in the lateral direction toward the groove wall 1112 on the other lateral side of the mounting groove 111, and the first elastic element 361 is in a compressed state and is restrained by the positioning block 37.

Referring to fig. 15b, after the BTB connector 20 is installed in the installation groove 111, the positioning block 37 is opened, the other end of the positioning block 37 is separated from the top end of the stopper 36, and the stopper 36 moves toward the groove wall 1112 on the other lateral side of the installation groove 111 in the lateral direction under the elastic force of the first elastic member 361, and clamps the BTB connector 20 in the installation groove 111 in the lateral direction with the groove wall 1112 on the other lateral side of the installation groove 111, thereby performing a lateral locking function.

Illustratively, referring to fig. 15b, after the BTB connector 20 is mounted in the mounting groove 111, the other end of the positioning block 37 is located between the stopper 36 and a groove wall 1111 of one lateral side of the mounting groove 111. The space between the stopper 36 and the groove wall 1111 of the lateral side of the mounting groove 111 is sufficiently utilized to receive the other end of the positioning block 37, which makes the structure of the cellular phone 1 compact.

In some possible embodiments, the bottom end of the stopper 36 facing the bottom wall of the mounting groove 111 is attached to the bottom wall of the mounting groove 111. With this arrangement, the stability of the stop block 36 clamping the BTB connector 20 with the groove wall 1112 on the other lateral side of the mounting groove 111 is improved, so that the BTB connector 20 is stressed uniformly in the lateral direction.

In some possible embodiments, referring to fig. 16, fig. 16 shows a schematic view of another clamping structure 39. The clamping structure 39 shown in fig. 16 includes: a first portion 391, a second portion 392, and a third portion 393 made of a soft elastomeric material. The first part 391 extends along the transverse direction (shown by X in fig. 16) and is attached to the bottom wall of the mounting groove 111, and two transverse ends of the first part 391 are connected with the second part 392 and the third part 393 respectively; the second portion 392 is attached to a groove wall 1111 of one lateral side of the mounting groove 111, and the third portion 393 is attached to a groove wall 1112 of the other lateral side of the mounting groove 111 to form the mounting groove 111.

This structure is similar to a USB boot, and a soft interference is provided by the clamping structure 39, so that the space between the mounting groove 111 and the BTB connector 20 is filled with a soft elastic material, thereby functioning as a lock. The soft elastic filling material may be rubber, and may be soft rubber, but is not limited to the soft elastic material.

The first portion 391 of the clamping structure 39 shown in fig. 16 described above corresponds, by way of example, to the lateral support plate 31 of the clamping structure shown in fig. 9 a. The second portion 392 of the clamp structure 39 shown in fig. 16 described above corresponds to the first clamp arm 32 of the clamp structure shown in fig. 9 a.
