For example, in specific use, the pressing member 1 is placed on the clamped flexible circuit board and the connector 10 on the main board 2, and then the corresponding plugging portion 11 and the corresponding slot 221 on the pressing member 1 and the main board 2 are plugged and matched, so that the effect of pressing and fixing the connector 10 and the flexible circuit board clamped together can be achieved.

The connection fixing structure of the electronic device provided in this embodiment is mainly applied to electronic devices, such as a mobile phone, a tablet, and the like. The pressing element 1 may be, for example, a steel body, an alloy body or the like.

According to the connection fixing structure of the electronic equipment, the pressing piece 1 and the main board 2 are arranged, at least two plug-in parts 11 which are arranged at intervals are arranged on the pressing piece 1, the main board 2 is provided with the slots 221 which are matched with the plug-in parts 11, and the slots 221 are matched with the plug-in parts 11 for plug-in connection, so that the flexible circuit board which is clamped together and the connector of the main board 2 are pressed and fixed between the pressing piece 1 and the main board 2. The flexible circuit board and the connector which are clamped together can be limited and fixed to a certain extent, so that the clamping effect between the flexible circuit board and the connector is guaranteed to a certain extent, and the possibility of looseness between the flexible circuit board and the connector is reduced. Meanwhile, since the connector and the flexible circuit board can be pressed and fixed by matching and plugging between the plugging part 11 and the slot 221, compared with the scheme of pressing the flexible circuit board and the connector by using tools such as screws, the connection fixing structure of the electronic device provided by the embodiment does not need a third-party tool when in use, for example, the intervention of a screwdriver, so that the connector and the flexible circuit board are pressed and fastened at a simple timing and are easy to operate. Meanwhile, as the main board 2 and the compression piece are detachably connected in an inserting manner, on one hand, the main board 2 and the compression piece 1 are convenient to connect, and the flexible circuit board and the connector are fast and easy to operate when being compressed and fixed; on the other hand, when one of the pressing member 1 and the main plate 2 is damaged, only the damaged part is needed, so that the integral scrapping of the main plate 2 and the pressing member 1 is avoided.

Referring to fig. 1, each of the insertion portions 11 includes a flange provided on the pressing member 1, the flange protruding in a direction away from the pressing member 1 and being insertable into a slot 221 on the main board 2. Meanwhile, in the groove width direction along the slot 221, the groove width of the slot 221 is smaller than the dimension of one side, close to the flange, of the pressing piece 1, when the flange is located in the slot 221, the pressing piece 1 is made to abut against the outer edge of the corresponding slot 221, and the slots of the slot 221 corresponding to the plugging portions 11 located on two sides of the connector 10 face the fixing space 3. The slot width direction of the slot 221 is specifically the Y-Y direction shown in fig. 5.

By making the insertion portion 11 a flange provided on the pressing member 1, the insertion groove 221 is provided on the main plate 2, and the groove width of the insertion groove 221 in the X-X direction is made smaller than the dimension of the pressing member 1 on the side close to the flange, that is, the step 5 is formed between the side close to the flange of the pressing member 1 and the flange.

Meanwhile, when the flange is located in the slot 221, the pressing piece 1 can resist the outer edge of the slot 221, that is, the step surface 51 on the pressing piece 1 is abutted against the outer edge of the slot 221, and as the notches of the slot 221 corresponding to the plugging portions 11 located at two sides of the connector 10 face the fixing space 3, when the plugging portions 11 are matched with the corresponding slots 221, the position of the pressing piece 1 relative to the main board 2 can be limited to a certain extent, the stability of connection between the pressing piece 1 and the main board 2 is ensured, and the pressing and fixing effect of the connection and fixing structure of the electronic device on the connector 10 and the flexible circuit board is improved.

For example, when two flanges are provided on the pressing member 1 and the two flanges are matched with the corresponding slots 221, they are positioned at the left and right sides of the connector 10. As shown in fig. 2, the pressing member 1 can be limited in the left-right direction, i.e., the X-X direction, with respect to the main plate 2.

For example, the insertion operation can be performed by means of the elasticity of the compression element 1 itself when the flanges on the compression element 1 are sequentially inserted into the corresponding flanges. For example, referring to fig. 2 to 4, the flange on the right side of the pressing member 1 may be first inserted into the slot 221 on the right side of the main board 2, and then the pressing member 1 may be deformed to a certain extent by using the elasticity of the pressing member 1 itself, so that the flange on the left side of the pressing member 1 may be easily inserted into the slot 221 on the left side of the main board 2, so as to realize the connection between the pressing member 1 and the main board 2.

In other embodiments, the plugging portion 11 may be an elastic buckle, and the elastic buckle may extend into the slot 221 and be engaged with the slot 221 in a matching manner.

The flange and the compression piece 1 are integrally formed, so that the integrity between the flange and the compression piece 1 is good, the structural strength is high, and the subsequent assembly is convenient.

In some embodiments, the corners of the pressing piece 1 are rounded, so that the situation that the pressing piece 1 is worn when contacting with an external object can be reduced to a certain extent, and the structure of the pressing piece 1 is protected.

The pressing piece 1 is a fixed flat plate attached to the connector 10, so that the contact area between the pressing piece 1 and the connector 10 can be increased to a certain extent, the attachment between the pressing piece 1 and the connector 10 is more stable and reliable, and the pressing and fixing effect of the connecting and fixing structure of the electronic equipment on the connector 10 and the flexible circuit board is improved.

In some embodiments, at least one of the flanges and the pressing member 1 has an elastic member 3 therebetween, and the flange may extend into the corresponding slot 221 when the elastic member 3 is contracted.

By arranging the elastic element 3 between at least one flange and the pressing element 1 and enabling the elastic element 3 to deform along the X-X direction, the arrangement is such that when the flange extends into the slot 221, especially when the flange close to one side of the elastic element 3 extends into the corresponding slot 221, the elastic element 3 can be contracted along the X-X direction by applying an external force to the elastic element 3, so that the relative distance between the notch of the slot 221 and the side of the flange far away from the pressing element 1 along the X-X direction is shortened, the flange can be conveniently extended into the slot 221, and the convenience and efficiency of connection between the pressing element 1 and the main board 2 can be improved to a certain extent.

For example, as shown in fig. 2 to 4, an elastic member 3 is provided between the pressing member 1 and the left flange, and when the device is specifically used, the right flange is first inserted into the slot 221 corresponding to the right side of the main board 2, then an external force is applied to the elastic member 3 to shrink the elastic member 3 in the X-X direction, and finally the left flange is inserted into the slot 221 corresponding to the left side of the main board 2.

In the present embodiment, the elastic member 3 includes a connecting portion 31 and two elastic arms 32, and the two elastic arms 32 are arranged at intervals in the insertion and extraction direction along the flange within the slot 221. Specifically, one of the elastic arms 32 is connected between the connecting portion 31 and the pressing member 1, wherein the other elastic arm 32 is connected between the connecting portion 31 and the flange, and the deformation gap 4 is provided between the two elastic arms 32. The direction of inserting and extracting the flange in the slot 221 is specifically the X-X direction shown in fig. 1.

By providing the elastic member 3 as a connecting portion 31 and two elastic arms 32 with one of the elastic arms 32 being located between the connecting portion 31 and the pressing member 1 and the other elastic arm 32 being located between the connecting portion 31 and the flange, as shown with reference to fig. 1, the elastic member 3 is made to form a "like a Chinese character 'ji' shaped structure.

For example, referring to fig. 1, by arranging two elastic arms 32 at intervals along the insertion and extraction direction (X-X direction) of the flange in the slot 221, and having a deformation gap 4 between the two elastic arms 32, when implementing, the flange can be conveniently inserted into the slot 221 on the left side by applying a force to the elastic arms 32, which can deform the two elastic arms 32 towards directions approaching each other, so as to drive the corresponding flange on the left side to move rightward. Thus, the elastic member 3 has a simple structure and is convenient to operate.

Of course, in other embodiments, the elastic member 3 may be a spring, an elastic strip, or other elastic structures.

In this embodiment, the flange and the slot 221 are two. In some embodiments, one of the flanges is inserted into the corresponding slot 221, and the other flange is located between the two slots 221 when the elastic member 3 is retracted into place.

By arranging two flanges and slots 221, for example, as shown in fig. 2 and 3, the two flanges are located on the left and right sides of the connector 10, and by arranging the slots of the slots 221 corresponding to the flanges toward the fixing space 3, the slots of the slots 221 corresponding to the flanges on the right side are directed to the left, and the slots of the slots 221 corresponding to the flanges on the left side are directed to the right, the connector 10 and the flexible circuit board can be fixed in the fixing space 3 when the two flanges are mated with the corresponding slots 221.

The number of flanges is reduced, so that the number of plugging times when the pressing piece 1 is connected with the main board 2 is reduced to a certain extent, and the efficiency when the pressing piece 1 is connected with the main board 2 is improved.

By inserting one of the flanges into the corresponding slot 221 and retracting the elastic member 3 into place, wherein the other flange is located between the two slots 221, for example, as shown in fig. 2 to 4, the right flange is first inserted into the right slot 221, and then the elastic member 3 is retracted into place, in fig. 3, it can be seen that the left flange is located on the right side of the left slot, so that the left flange is more convenient to be inserted into the left slot 221, thereby further improving the efficiency of connecting the pressing member 1 and the main board 2.

The motherboard 2 includes a board body 21 and a shielding case 22 disposed on the board body 21 for shielding an external interference signal of the motherboard 2, the connector is disposed on the board body 21, and the slot 221 is disposed on the shielding case 22.

Through setting up mainboard 2 into plate body 21 and shield cover 22 to make connector 10 be located plate body 21, slot 221 is located shield cover 22, sets up like this, and the simple structure of mainboard 2, and in a flexible way has employed the structure of mainboard 2 self so that the setting of slot 221, and convenient, easy operation when compressing tightly fixed flexible circuit board and connector 10.

In some embodiments, at least a portion of the pressing member 1 corresponding to the flexible circuit board is a convex portion 12 protruding toward a direction away from the main board 2, and the flexible circuit board and the connector are pressed and fixed between the convex portion 12 and the main board 2. Meanwhile, the top surface of the shield 22 is at a lower level than the top surface of the flexible circuit board.

By arranging that at least the part of the pressing member 1 corresponding to the flexible circuit board and the connector 10 is the convex part 12 and the flexible circuit board and the connector are pressed and fixed between the convex part 12 and the main board 2, the convex part 12 can further play a certain limiting role on the connector 10 and the flexible circuit board. For example, referring to fig. 2 and 3, the projection 12 is provided to limit the positions of the connector 10 and the flexible circuit board in the X-X direction.

Meanwhile, referring to fig. 5 to 6, by making the height of the top surface of the shield case 22 lower than the height of the top surface of the flexible circuit board, the height of the slot 221 is lower than the height of the top surface of the protrusion 12 while the connector 10 and the flexible circuit board are accommodated and fixed by the protrusion 12 and the main board 2, thereby correspondingly reducing the height of the shield case 22 (the Z-Z dimension shown in fig. 2 and 5), saving the material of the shield case 22, and reducing the cost to a certain extent.

In some embodiments, the side of the flange remote from the compression member 1 has a guide portion for guiding the flange when it is inserted into the slot 221.

By arranging the guide part on the flange, the flange can conveniently extend into the slot 221, and convenience and efficiency of matching the flange with the slot 221 are improved.
