Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example one

Fig. 1 is a schematic structural diagram of a fixing structure of a connector according to an embodiment of the present invention; fig. 2 is a schematic structural view of a pressing member according to an embodiment of the present invention. As shown in fig. 1 and 2, the present embodiment provides a fixing structure (hereinafter referred to as a fixing structure) of a connector, which is used to press-fix a connector 400 onto a circuit board 300.

The connector 400 is usually located in mobile terminal products such as a mobile phone, a tablet computer, a smart watch, a digital camera, and the like, the connector 400 may be, for example, a BTB connector 400 or an FPC connector 400, and correspondingly, the circuit board 300 may be a printed circuit board 300(PCB) or a flexible printed circuit board 300(FPC), and the BTB connector 400 is used for connecting between two PCBs, so that the two PCBs are mechanically and electrically connected; the FPC connector 400 is used to realize connection of an FPC to other components (e.g., a liquid crystal module LCM).

In practical applications, the connector 400 may loosen or fall off during use, which may result in the connector 400 becoming non-functional. In order to prevent the connector 400 from loosening or falling off, in the prior art, the connector 400 is generally fixed and limited by a steel sheet, specifically, the steel sheet is pressed on the connector 400, and two ends of the steel sheet are fixed on the circuit board by screws.

Because the both ends of steel sheet pass through the screw connection on the circuit board, therefore the both ends of steel sheet need set up the screw, can understand that the screw can not be seted up at the marginal position of steel sheet to influence the intensity of steel sheet, and the screw warp easily or the fracture, need reserve sufficient space and set up the screw, therefore the whole space that occupies of steel sheet is great, and this can influence mobile terminal's whole size, and adopt the screw can increase cost.

The fixing structure provided by the embodiment is used for fixing the connector 400, and the fixing structure is used for preventing the connector 400 from loosening or falling off in the using process, so that the problems of large occupied space and high cost of the fixing structure of the connector 400 in the prior art are solved.

Specifically, the fixing structure includes a pressing member 100 and two positioning members 200, the pressing member 100 is used for pressing the connector 400, that is, the pressing member 100 is used for fixing the connector 400, so as to prevent the connector 400 from loosening or falling off, and the positioning members 200 are used for positioning and fixing the pressing member 100, so as to ensure the stability of the pressing member 100.

As shown in fig. 1 and 2, the pressing member 100 includes a main body 110 and a connecting portion 120, the connecting portion 120 is located at two ends of the main body 110, the main body 110 of the pressing member 100 presses on the connector 400, and the connector 400 is prevented from loosening or falling off by the pressure action of the main body 110 on the connector 400; the connecting parts 120 at the two ends of the main body part 110 extend out of the two ends of the connector 400, and the pressing piece 100 is fixed on the connector 400 through the connecting parts 120 at the two ends of the main body part 110, so that the pressing piece 100 can effectively press and fix the connector 400.

As shown in fig. 1, the positioning member 200 is used to cooperate with the connecting portion 120 of the compression member 100 to fix the compression member 100 to the connector 400. Specifically, the circuit board 300 is provided with two positioning elements 200, the two positioning elements 200 are respectively located at two sides of the pressing element 100, the two positioning elements 200 respectively correspond to the connecting portions 120 at two ends of the pressing element 100, and the pressing element 100 is fixed by clamping the positioning elements 200 and the outer edges of the corresponding connecting portions 120.

In this embodiment, the positioning members 200 are disposed on two sides of the pressing member 100, and the connecting portions 120 at two ends of the pressing member 100, which extend out of the connector 400, are clamped with the positioning members 200, so as to fix the pressing member 100. Thus, the part of the pressing member 100 extending out of the connector 400 can have a smaller length, and only the outer edge of the connecting portion 120 needs to be ensured to be clamped with the positioning member 200; and the two ends of the steel sheet do not need to be designed with enough extension length like the steel sheet in the prior art to reserve the positions for arranging the screw holes, so that the two ends of the steel sheet are fixed on the circuit board 300 by adopting a screw fixing mode.

Therefore, the fixing structure provided by this embodiment fixes the pressing member 100 by using the outer edges of the connecting portions 120 at the two ends of the pressing member 100 to be clamped with the positioning member 200, so that the length of the pressing member 100 can be reduced, and the overall occupied space of the fixing structure is smaller, thereby reducing the overall size of the mobile terminal.

In addition, in the embodiment, since the connection portions 120 at the two ends of the pressing member 100 are clamped with the positioning member 200, the pressing member 100 is prevented from being fixed by a screw connection method, and screws are not used, so that the cost of the fixing structure can be saved, and the cost of the mobile terminal can be reduced.

The fixing structure of the present embodiment is used to fix the connector 400 to the circuit board 300, and therefore, the fixing structure should have sufficient strength and rigidity to ensure that the fixing structure can stably connect the connector 400 to the circuit board 300 and ensure the workability of the connector 400. In practical applications, the pressing member 100 and the positioning member 200 in the fixing structure may be metal members, for example, the pressing member 100 and the positioning member 200 are made of stainless steel, so that the pressing member 100 and the positioning member 200 have good rigidity, and it is ensured that the positioning member 200 can firmly fix the pressing member 100, and the pressing member 100 is tightly pressed on the connector 400.

For the connection between the positioning member 200 and the circuit board 300, the positioning member 200 may be connected to the circuit board 300 by soldering, for example, to ensure that the positioning member 200 is firmly fixed. In this embodiment, when the fixing structure is installed, the two positioning members 200 may be connected to two sides of the connector 400 respectively, and then the pressing member 100 is placed on the connector 400, and the connecting portions 120 at two ends of the pressing member 100 are fixed to the positioning members 200 at two sides in a clamping manner.

It can be understood that, compared with the way of forming screw holes at both ends of the pressing member 100 and on the circuit board 300 and fixing the pressing member 100 on the circuit board 300 by using screws, the connecting parts 120 at both sides of the pressing member 100 are clamped with the positioning part 200, so that the pressing member 100 can be conveniently mounted and dismounted, and the assembly and dismounting efficiency of the fixing structure can be improved.

As shown in fig. 1, regarding the manner that the connecting portion 120 of the pressing member 100 is engaged with the positioning member 200, in a possible embodiment, the connecting portion 120 of at least one end of the pressing member 100 may be connected with the positioning member 200 by a snap 121. In this embodiment, the connecting portion 120 at the end of the pressing member 100 and the corresponding positioning member 200 may be connected by a buckle 121, so as to realize the clamping between the connecting portion 120 of the pressing member 100 and the positioning member 200.

For the connection between the pressing member 100 and the positioning member 200 through the buckle 121, specifically, at least one connection portion 120 of the pressing member 100 may be provided with the buckle 121, and the positioning member 200 corresponding to the buckle 121 may have a slot, and the buckle 121 is snapped into the slot. As shown in fig. 1 and 2, a connecting portion 120 at an end of the pressing member 100 is provided with a buckle 121, a positioning member 200 corresponding to the connecting portion 120 is provided with a slot, and a position of the buckle 121 matches a position of the slot.

Through set up buckle 121 on the connecting portion 120 that compresses tightly piece 100, set up the draw-in groove (not shown in the figure) on corresponding setting element 200, at the installation and compress tightly the in-process of piece 100, compress tightly piece 100 promptly and just when moving towards connector 400, buckle 121 gets into the draw-in groove gradually, wait to compress tightly piece 100 and install in place, in buckle 121 blocks the draw-in groove completely, through the backstop effect of draw-in groove to buckle 121, fix compressing tightly piece 100.

For the connection between the pressing member 100 and the positioning member 200 through the buckle 121, in some other embodiments, the buckle 121 may also be disposed on the positioning member 200, and the latching groove is disposed on the connecting portion 120 of the pressing member 100 corresponding to the positioning member 200, and during the process that the pressing member 100 is moving towards the connector 400, the latching groove on the connecting portion 120 moves towards the connector 400, so that the buckle 121 gradually enters the latching groove, and when the buckle 121 is fully latched into the latching groove, the pressing member 100 is fixed on the connector 400.

It should be noted that, no matter the buckle 121 is disposed on the connecting portion 120 of the pressing member 100 and the slot is disposed on the positioning member 200, or the buckle 121 is disposed on the positioning member 200 and the slot is disposed on the connecting portion 120 of the pressing member 100, for the position of the slot or the buckle 121 on the positioning member 200, when the buckle 121 is completely snapped into the slot, the pressing member 100 presses on the connector 400, so as to ensure the fixing effect of the pressing member 100 on the connector 400.

In addition, it can be understood that, no matter whether the catch 121 is provided on the connecting portion 120 of the pressing member 100 or the positioning member 200, the portion where the catch 121 is provided should have elasticity. As shown in fig. 1, taking the example that the latch 121 is disposed on the connecting portion 120 of the pressing member 100, one end of the positioning member 200 facing the connecting portion 120 has a guide wall 210, and the card slot is disposed on the guide wall 210, for example, the card slot is located on the guide wall 210 near the circuit board 300.

In the process that the pressing member 100 moves towards the connector 400, the catch 121 of the connecting portion 120 moves along the guide wall 210 of the positioning member 200, the pressure between the catch 121 and the guide wall 210 increases, and the catch 121 generates an elastic force towards the body portion 110 of the pressing member 100, so that when the catch 121 moves to the card slot, the elastic force of the catch 121 acts to enable the catch 121 to be clamped into the card slot.

In practical applications, if the latch 121 is disposed on the guide wall 210 of the positioning member 200 and the latch 121 faces the connecting portion 120 of the pressing member 100, the elastic force of the latch 121 should make it compressed toward the guide wall 210, as the pressing member 100 moves toward the connector 400, the connecting portion 120 of the pressing member 100 abuts against the guide wall 210 of the positioning member 200 and gradually compresses the latch 121 toward the guide wall 210, and when the slot of the connecting portion 120 moves to correspond to the latch 121, the elastic force of the latch 121 makes it latch into the slot.

For the reason that the latch 121 is disposed on the guide wall 210 of the positioning member 200, for example, the latch 121 may be a cantilever structure, one end of the latch 121, which is away from the circuit board 300, is connected to the guide wall 210 of the positioning member 200, one end of the latch 121, which is close to the circuit board 300, is suspended, and the latch 121 is inclined toward the pressing member 100 from the end of the latch 121, which is connected to the guide wall 210, to the suspended end, when the latch 121 is pressed, the suspended end moves toward the guide wall 210 of the positioning member 200, so that the latch 121 can be stably latched in the latching slot of the connecting portion 120 of the pressing member 100 by the elastic force of the latch 121.

As shown in fig. 2, in this embodiment, in order to facilitate the processing of the positioning element 200, the buckle 121 may be selectively disposed on the connecting portion 120 of the pressing element 100, specifically, the connecting portion 120 provided with the buckle 121 may have a bent portion 122, a first elastic arm 123 facing the main body portion 110 and a second elastic arm 124 facing away from the main body portion 110 are respectively formed on two sides of the bent portion 122, and the buckle 121 may be located on a surface of the second elastic arm 124 facing the positioning element 200.

In order to make the portion of the connecting portion 120 where the buckle 121 is disposed have elasticity, the connecting portion 120 has a bending portion 122, a first elastic arm 123 and a second elastic arm 124 are respectively formed on two sides of the bending portion 122, the first elastic arm 123 faces the main body portion 110 of the pressing member 100, and the second elastic arm 124 faces away from the main body portion 110, that is, the second elastic arm 124 is located on the side of the connecting portion 120 facing the positioning member 200. As described above, in the present embodiment, the pressing member 100 is a metal member, and thus the bending portion 122 is formed on the connecting portion 120, the first elastic arm 123 and the second elastic arm 124 are formed on both sides of the bending portion 122, and when the second elastic arm 124 is pressed, the second elastic arm 124 and the first elastic arm 123 are compressed, and the second elastic arm 124 is biased toward the first elastic arm 123.

In the process of installing the pressing member 100, the second elastic arm 124 of the connecting portion 120 abuts against the guiding wall 210 of the positioning member 200, and the guiding wall 210 presses the second elastic arm 124, so that the second elastic arm 124 is compressed, and when the pressing member 100 moves to the position where the latch 121 on the second elastic arm 124 corresponds to the latch slot of the positioning member 200, the elastic force of the second elastic arm 124 enables the latch 121 to be latched into the latch slot.

In this embodiment, the pressing member 100 may be an integrally formed member, for example, the main body portion 110 of the pressing member 100 and the connecting portions 120 at two ends of the main body portion 110 may be formed by forming a metal plate to form the pressing member 100; alternatively, the main body 110 and the connecting portion 120 of the pressing member 100 may be formed separately, and then the connecting portion 120 may be connected to two ends of the main body 110 by welding, etc., which is not limited in this embodiment.

Since the positioning member 200 is directly connected to the circuit board 300 and the positioning member 200 has the guide wall 210 facing the pressing member 100, for example, the cross section of the positioning member 200 may be in an "L" shape, the positioning member 200 has a fixing wall attached to the circuit board 300, and the fixing wall and the guide wall 210 are perpendicular to each other, so that the contact area between the positioning member 200 and the circuit board 300 can be increased, and the positioning member 200 can be ensured to be firmly connected; alternatively, the positioning member 200 may have other structures according to the specific layout of the components in the mobile terminal.

It should be noted that, in the present embodiment, specific shapes of the positioning elements 200 on both sides of the pressing member 100 are not limited, and the shapes and sizes of the two positioning elements 200 may be completely the same, which is convenient for processing and manufacturing the positioning elements 200, or the structural shapes of the two positioning elements 200 may also be different, only the positioning elements 200 are required to be fixed on the circuit board 300, and the positioning elements 200 can be clamped with the connecting portions 120 of the pressing member 100.

In order to form the connecting portion 120 having the bent portion 122 at the end of the main body 110, in a possible embodiment, the end of the main body 110 may be bent upwards to form the first elastic arm 123, and the bent portion 122 is located at an end of the first elastic arm 123 far away from the connector 400.

The end of the main body 110 is bent upwards to form the first elastic arm 123, and after the first elastic arm 123 is formed, the first elastic arm 123 can be further bent to form the bent portion 122 and the second elastic arm 124, so that the position of the bent portion 122 is the end of the first elastic arm 123 far away from the connector 400, that is, the bent portion 122 is located above the main body 110, and the bent portion 122 is further away from the circuit board 300, so that a space for forming the first elastic arm 123 and the second elastic arm 124 is formed between the bent portion 122 and the circuit board 300, and after the buckle 121 of the connecting portion 120 is clamped with the clamping slot of the positioning member 200, the main body 110 of the pressing member 100 is pressed against the connector 400.

As shown in fig. 2, in one embodiment, the bent portion 122 may be bent toward the connector 400. That is to say, after the end of the main body 110 is bent upwards to form the first elastic arm 123, the other end of the first elastic arm 123 is bent downwards to form the bent portion 122 and the second elastic arm 124, the position where the bent portion 122 is located is the highest position of the pressing member 100, that is, in the pressing member 100, the distance between the bent portion 122 and the circuit board 300 is the largest, so that the distance between the position where the bent portion 122 is located and the main body 110 is the largest thickness of the whole pressing member 100. By bending the bent portion 122 toward the connector 400, the pressing member 100 can have a small thickness as a whole, and the space occupied by the pressing member 100 in the thickness direction thereof is small.

In addition, the bending portion 122 is bent toward the connector 400, the first elastic arm 123 and the second elastic arm 124 on two sides of the bending portion 122 are both located on the same side of the bending portion 122, that is, the first elastic arm 123 and the second elastic arm 124 are both located between the bending portion 122 and the circuit board 300, so that when the connecting portion 120 is pressed by the guide wall 210 of the positioning member 200, the second elastic arm 124 is more easily contracted toward the first elastic arm 123, and after the latch 121 on the second elastic arm 124 corresponds to the slot of the positioning member 200, the second elastic arm 124 is more easily rebounded to allow the latch 121 to be inserted into the slot, and the connecting portion 120 can better maintain the elastic force.

In this embodiment, the connecting portions 120 at the two ends of the pressing member 100 and the corresponding positioning members 200 can be connected through the buckles 121, for example, the connecting portions 120 at the two ends of the pressing member 100 all have the bending portions 122, the two connecting portions 120 can have the same structure, the buckles 121 are arranged on the surfaces of the two connecting portions 120 facing the positioning members 200, the clamping grooves can be arranged on the positioning members 200 at the two sides of the pressing member 100, the buckles 121 on the two connecting portions 120 are clamped into the clamping grooves of the positioning members 200 at the two sides, and the pressing member 100 is fixed.

In order to facilitate the detachment of the pressing member 100, in one possible embodiment, the connecting portion 120 at one end of the pressing member 100 and the positioning member 200 may be connected by a buckle 121, the connecting portion 120 at the other end of the pressing member 100 may have a locking protrusion 125 protruding toward the positioning member 200, and the positioning member 200 may be provided with a slot into which the locking protrusion 125 may be inserted.

As shown in fig. 1 and fig. 2, in the present embodiment, the connecting portion 120 at one end of the pressing member 100 is connected to the corresponding positioning member 200 through a buckle 121, and another clamping manner is adopted between the connecting portion 120 at the other end of the pressing member 100 and the corresponding positioning member 200, specifically, the connecting portion 120 at the other end of the pressing member 100 is provided with a clamping protrusion 125, the clamping protrusion 125 extends toward the positioning member 200, a slot (not shown) is formed in a position of the positioning member 200 corresponding to the clamping protrusion 125, and when the connecting portion 120 of the pressing member 100 is connected to the positioning member 200, the clamping protrusion 125 is directly inserted into the slot of the positioning member 200 to fix the connecting portion 120 of the pressing member 100.

When the pressing member 100 is installed, the end of the pressing member 100 having the locking protrusion 125 may be firstly locked into the slot of the positioning member 200, the end of the pressing member 100 is firstly positioned, then the other end of the pressing member 100 is moved toward the connector 400, and the locking buckle 121 of the connecting portion 120 at the other end of the pressing member 100 is locked into the locking slot of the positioning member 200.

On one hand, when the pressing member 100 is detached, only one end of the pressing member 100 having the buckle 121 needs to be removed from the clamping groove of the positioning member 200, and then the buckle 125 at the other end of the pressing member 100 is removed from the slot of the positioning member 200, so that the pressing member 100 is detached conveniently; on the other hand, the mode that the convex card 125 is inserted into the slot is convenient for the positioning of the pressing member 100, and the problem that the buckles 121 at the two ends can not completely correspond to the slots of the positioning member 200 when the two ends of the pressing member 100 are the buckles 121 is avoided.

In addition, one end of the pressing member 100 is in the form of a locking protrusion 125, and the other end is in the form of a buckle 121, so that the connection between the pressing member 100 and the positioning members 200 on both sides is firmer. Since the end of the pressing member 100 having the catching protrusion 125 does not need to be subjected to processes such as bending and machining the catching hook 121, the machining efficiency of the pressing member 100 can be improved, and the cost of the pressing member 100 can be reduced.

As shown in fig. 2, in order to make the connection between the end of the pressing member 100 having the locking protrusion 125 and the positioning member 200 more stable, in a possible embodiment, the end of the locking protrusion 125 may have a stopping portion 1251 tilted away from the circuit board 300, and after the locking protrusion 125 is inserted into the slot, the stopping portion 1251 stops at a side of the positioning member 200 away from the main body 110.
