Detailed Description

The embodiment of the application provides a solution that pressfitting support was fixed in advance to realize firm fixed effect in advance and the convenient and easy nature of dismantlement. In the specific application of electronic equipment such as cell-phone, panel computer, notebook computer and smart screen, based on different assembly process flows, can make the pre-installation reliability of waiting to press the component effectively promote, can promote simultaneously and produce line efficiency and assembly quality.

Without loss of generality, the present embodiment takes the BTB connector 10 as a description main body, and details a pre-fixing structure scheme of a pressing bracket for pressing a component to be pressed. The BTB connector shown in the figure can realize connection of a component to an FPC (Flexible Printed Circuit) 20. It should be understood that the functional structure of the BTB connector 10 and the specific implementation of the connection relationship are not the core invention of the present application, and therefore, the pre-fixing structure of the press-fit bracket claimed in the present application is not substantially limited.

In the electronic equipment who uses the BTB connector, for the characteristics of adaptation BTB connector, utilize pressfitting support 30 to assemble the location, can ensure the connection stability between its public female head, and then prevent to connect the pine and take off and lead to appearing the problem such as functional failure. In actual assembly, the press-fit fixing of the bracket 30 includes two operation links of pre-fixing and locking and fixing. At the press-fit bracket assembly station, the bracket 30 and the housing 40 of the electronic device are preliminarily fixed, and after the flow is transferred to the locking and fixing station, the final locking and fixing is completed by fasteners (not shown) such as screws.

In order to simplify the drawing to clearly illustrate the main structure and connection of the present embodiment, only the mounting holes (30a, 40a) of the screws are shown on the bracket 30 and the housing 40.

For example, but not limited to, between the press-fit bracket assembly station and the screw locking station, other assembly stations are configured. It can be understood that if the pre-fixing effect of the pressing bracket 30 is not good, it will cause the screw locking station to be tilted, deviated, and dropped. The reliability of the pre-fixing structure of the bracket 30 directly affects the production line efficiency and the assembly quality.

In the present embodiment, the housing 40 of the electronic device is used as a fixing member fitted to the stand 30. The term "fixing member" herein means a structure that is held relatively fixed in an assembled relationship of the constituent parts of the apparatus, and is used for mounting the device without a dynamic fitting relationship, such as but not limited to the housing 40 of the electronic apparatus 1 shown in the drawings. In practical application, the electronic equipment can be selected according to the overall design requirements of the corresponding electronic equipment,

in other embodiments, the fixing member for the mounting bracket 30 may also be a main board of the electronic device based on actual stress.

In addition, the fixing component can also be a component fixed on a shell or a main board of the electronic equipment, so long as the bearing requirement is met and the basic function of the corresponding fixing component is taken into consideration.

For ease of description, three directions are defined herein for the cradle 30 to mate with the BTB connector 10: the first direction X is a direction of the pressing force provided by the support 30, the second direction Y is a sliding direction of the switching position of the support 30, and the third direction Z is a direction perpendicular to the first direction X and the second direction Y; the portion of the holder body 33 that is press-fitted to the BTB connector 10 is formed in a plane formed by the third direction Z and the second direction Y.

The pressing bracket pre-fixing structure provided by the embodiment of the application comprises pre-fixing parts (31, 32) at two end sides of the bracket 30 in the second direction Y, and two limiting parts (41, 42) arranged on the shell 40. Two limiting parts are formed at the position of the shell 40 opposite to the bracket in the first direction X, and two pre-fixing parts and the two limiting parts are respectively constructed to form two sliding limiting pairs.

Wherein, two slide spacing pairs all configure to: the pre-fixing parts (31, 32) can slide along the second direction Y relative to the corresponding limiting parts (41, 42) so as to be switched between the installation position and the pre-fixing position, and the limiting parts (41, 42) can limit the pre-fixing parts (31, 32) located at the pre-fixing position in the first direction. Here, the "mounting position" refers to an initial position where the bracket 30 is engaged with the BTB connector 10, and in this state, the limiting portion does not have a limiting effect on the corresponding pre-fixing portion; the "pre-fixing position" refers to an adaptive position reached by the bracket 30 after sliding displacement along the second direction Y, and in this state, the limiting portion forms a limit on the corresponding pre-fixing portion in the first direction X, so as to complete reliable pre-fixing of the press-fit bracket.

In the two sliding limiting pairs, the limiting part of at least one sliding limiting pair forms limiting after the pre-fixing part is switched to the pre-fixing position; that is to say, at least one limit relationship is required to be formed after the pre-fixing portion is switched to the pre-fixing position, so that the basic assembly requirement of the press-fit support is met, and the assembly or disassembly of the support 30 is convenient to realize.

In specific implementation, the two sliding limiting pairs can be configured to be switched to a preset position and then form the limiting. That is, when the two pre-fixing portions (31, 32) are located at the "mounting position", neither of the two limiting portions (41, 42) forms a limit for the corresponding pre-fixing portion in the first direction X; the bracket 30 slides and displaces along the second direction Y, and when the two pre-fixing parts (31, 32) are located at the pre-fixing position, the two limiting parts (41, 42) respectively limit the corresponding pre-fixing parts in the first direction X.

Wherein, an elastic element 50 is arranged between the body 33 of the bracket 30 and the BTB or the fixing member, and the elastic element 50 can be pressed to generate deformation at least in the first direction X; in other words, the elastic element 50 needs to provide a restoring force to the bracket 30 in the pressing direction, and actually, the elastic element 50 can also have the capability of elastically deforming in other directions, rather than being limited to having the capability of deforming under pressure only in the first direction X.

Thus, after the pre-fixing is completed, based on the compression deformation in the first direction X, the elastic member 50 can apply an acting force to the bracket body 33 and form a static friction force therebetween, so that the bracket 30 can maintain a non-slip state in a plane perpendicular to the first direction X, thereby achieving a reliable pre-fixing of the press-fit bracket 30.

By the application of the scheme, the press-fit support has higher reliability after being fixed in advance, and the possibility of failure of the pre-fixing in the station transfer process is effectively avoided. In addition, the operator can do without the instrument and carry out pre-fixing operation and reverse maintenance operation, and when carrying out reverse maintenance dismantlement operation, need not change the auxiliary material and clear to glue.

It should be noted that the specific functional implementation of the two sliding limiting pairs may adopt different structural forms, and meanwhile, in the limiting relationship established in the first direction X, the two sliding limiting pairs may be formed after the pre-fixing portion is switched to the pre-fixing position, or both may be formed after the pre-fixing portion is switched to the pre-fixing position, and the following description is respectively given by corresponding embodiments:

example one

Referring to fig. 1 and fig. 2, fig. 1 is a schematic diagram illustrating a usage state of the pre-fixing structure of the press-fit bracket according to the present embodiment, and fig. 2 is an exploded view illustrating an assembly relationship of the pre-fixing structure of the press-fit bracket shown in fig. 1.

As shown in the figure, the first pre-fixing portion (31) and the second pre-fixing portion (32) on both end sides of the bracket 30 are respectively provided corresponding to the first limiting portion (41) and the second limiting portion (42) provided on the housing 40. Referring to fig. 3 and 4 together, fig. 3 is a top view of fig. 1, and fig. 4 is a sectional view taken along a line a-a of fig. 3.

In this embodiment, the first pre-fixing portion is a clamping plate 31 extending from the body 33 of the bracket 30, the first limiting portion includes a limiting groove 41, the clamping plate 31 can be inserted into the limiting groove 41 along the second direction Y, and the limiting groove 41 limits the clamping plate 31, i.e., forms a sliding limiting pair. The second pre-fixing portion includes a strip-shaped hole 32 with a length along the second direction Y, the second position-limiting portion 42 includes a positioning column 42 inserted into the strip-shaped hole 32 along the first direction X, a hook 421 is provided at an extending end of the positioning column 42, and the hook 421 extends toward the body 33 of the bracket along the second direction to form a position-limiting mechanism after the strip-shaped hole 32 is switched to the pre-fixing position, i.e., to form another sliding adapting pair.

Of course, the size of the retaining groove 41 in the second direction Y is larger than the size of the card 41, so that the card 41 is still placed in the retaining groove 41 after the strip-shaped hole 32 is switched to the pre-fixing position along with the bracket 30.

When the bracket 30 is assembled, the clamping plate 31 at one end side is obliquely inserted into the limiting groove 41, and the strip-shaped hole 32 at the other end side is sleeved on the positioning column 42, specifically, the mounting position shown in fig. 5; next, the bracket 30 is pressed along the first direction X, the elastic member 50 made of foam is deformed under pressure, and then the bracket 30 is pressed and pushed to slide along the second direction Y, in the process, the clamping plate 41 slides and displaces in the limiting groove 41, and the positioning column 42 slides and displaces in the strip-shaped hole 32 until the hook 421 at the end of the positioning column 42 is buckled on the surface of the bracket body 33, specifically, as shown in the pre-fixing position shown in fig. 6, which is an enlarged view of the portion i in fig. 4.

After the support pre-fixing operation is finished, the manual assembly downward pressure is removed, the reaction force formed by the compressed foam acts on the support 30 along the first direction X, the corresponding structures of the support 30 are respectively contacted with the hook surface of the positioning column 42 and the inner surface of the limiting groove 41, and the force balance is achieved; at this time, the static friction force between the two can effectively prevent the pressing bracket 30 from slipping and loosening, and realize the pre-fixation in the XYZ three directions.

In this embodiment, the elastic member 50 is located between the FPC20 and the bracket 30 to provide the above-mentioned static friction force and to press and position the FPC 20.

The limiting groove 41 and the positioning post 42 may be integrally formed with the housing 40. It is understood that the limiting groove 41 and the positioning post 42 in the present embodiment are not limited to be formed on the housing 40 as the base fixing structure. In other embodiments, both of them may be disposed on a fixing member such as a main board (not shown).

Of course, it is also possible to adopt such a design, for example, but not limited to, the limiting groove and the positioning post are respectively configured as independent components (not shown in the figure), and then fixed on the housing or the main body by welding or the like, and the function of the basic fixing structure can also be achieved.

In addition, the material of the bracket 30 may be stainless steel or aluminum alloy. This includes, but is not limited to, stainless steel, aluminum alloys, engineering plastics (which may be, for example, ABS, PC, PBT, or the like). The elastic member 50 can be made of foam, which is a material foamed by plastic particles and has the characteristics of elasticity, light weight, quick pressure-sensitive fixation and the like; in practical applications, the elastic member 50 may be pre-assembled on the surface of the reinforcement of the BTB connector 10 or the surface of the housing 40 of the electronic device, and may also provide the force for establishing the static friction force; such as but not limited to adhesive attachment, to prevent displacement of the resilient member during assembly operations. Alternatively, the elastic member 50 may be provided on the surface of the holder body 33 opposite to the BTB connector 10.

In other practical applications, the elastic member 50 may be made of silicone. The silica gel has the main component of silicon dioxide and has the characteristics of stable chemical property and better thermal stability.
