In the related art, a contact connector is formed by assembling a housing and two cover plates, and when the contact connector is applied to the electronic device, the cover plates and the electronic device are fixed. Since the structure of the contact connector is thick, a large space needs to be reserved in the electronic device for mounting of the contact connector, which affects the development of the electronic device towards the direction of thinning.

The objects of the disclosure are to provide a contact connector and an electronic device so as to reduce a thickness of the contact connector, which is conductive to thinning of the electronic device.

According to some examples of the disclosure, referring to FIG. 1 to FIG. 6, a contact connector is provided. The contact connector includes a substrate 10 and metal elastic sheets 20, the substrate 10 includes a first side 101 and a second side 102 opposite to each other, the metal elastic sheets 20 include fixed sections 201 and free sections 202 connected with each other, the fixed sections 201 are fixed to the substrate 10, the free sections 202 are provided with connection contacts 203, the substrate 10 is provided with through holes 103 penetrating through the first side 101 and the second side 102, the connection contacts 203 penetrate through the through holes 103 to protrude out of the first side 101, and the second side 102 is provided with mounting portions 104 configured to assemble with an electronic device 100.

By means of the above technical solution, when the contact connector provided by the disclosure is assembled on a fitting or an accessory in the electronic device 100, the mounting portions 104 on the second side 102 of the substrate 10 are configured to be assembled with the electronic device 100, in this way, the substrate 10 can be directly assembled with the electronic device 100 without other structural parts for assembling with the electronic device 100, so that the contact connector does not need to include other structural parts, the quantity of parts of the contact connector can be reduced, and the thickness of the contact connector can be lowered, which is conductive to thinning of the electronic device 100. After the contact connector is assembled with the fitting or the accessory in the electronic device 100, the connection contacts 203 on the metal elastic sheets 20 are exposed to the electronic device 100 so as to be able to make contact with exposed metal connection points of another electronic device 100, so that the two electronic devices are electrically connected to realize the functions of charging or data transmission or the like.

In some examples, the contact connector may include a plurality of metal elastic sheets 20, the plurality of metal elastic sheets 20 are arranged at intervals, and the connection contacts 203 of the plurality of metal elastic sheets 20 are colinear, that is, the connection contacts 203 of the plurality of metal elastic sheets 20 are located on the same straight line, the same arc or any curve, in other words, the arrangement of the connection contacts 203 of the plurality of metal elastic sheets 20 may have any appropriate design according to actual requirements, which is not specifically limited in the disclosure.

In the disclosure, the included angle between the free sections 202 and the fixed sections 201 of the side metal elastic sheets 22 may be any angle in intervals of 1° to 89° or 91° to 179°, which is not specifically limited in the disclosure. In addition, the two side metal elastic sheets 22 may have different shapes, that is, the included angles between the free sections 202 and the fixed sections 201 of the two side metal elastic sheets 22 are different. For example, in an implementation, the included angle between the free section 202 and the fixed section 201 of one of the side metal elastic sheets 22 may be an obtuse angle, such as 130°, and the included angle between the free section 202 and the fixed section 201 of the other side metal elastic sheet 22 may also be an obtuse angle 145°.

In some examples, referring to FIG. 2 and FIG. 4, in order to reliably assemble the contact connector and the electronic device 100, the mounting portions 104 may be disposed on two opposite side portions of the substrate 10 respectively.

The mounting portions 104 may be constructed in any appropriate way. Alternatively, referring to FIG. 2 and FIG. 4, the mounting portions 104 may be constructed as glue accommodating grooves, the glue accommodating grooves are concave from the second side 102 to the first side 101 and extend in a direction parallel to a length direction of the metal elastic sheets 20, and the glue accommodating grooves are configured to accommodate an adhesive to fix the substrate 10 and the electronic device 100. In other implementations, the mounting portions 104 may also be constructed as threaded holes, and in this case, fasteners (e.g., screws and pins) penetrate through the threaded holes to fix the substrate 10 and the electronic device 100. In some other implementations, the substrate 10 and the electronic device 100 may be assembled together through buckles and clamping grooves matched with each other, and in this case, the mounting portions 104 may be provided with one of the buckles and clamping grooves, the electronic device 100 is provided with another one of the buckles and the clamping grooves, and thus the substrate 10 and the electronic device 100 are connected in a clamped mode. In addition, the substrate 10 may also be assembled to the electronic device 100 in other appropriate ways, which is not specifically limited in the disclosure.

In some examples, the fixed sections 201 may be fixed to the substrate 10 in any appropriate way. Alternatively, the fixed sections 201 are fixed on the substrate 10 through injection molding, part of the fixed sections 201 are exposed to the substrate 10, and as shown in FIG. 2, the parts of the fixed sections 201 exposed to the substrate 10 may be configured to be electrically connected with the electronic device 100.

The fixed sections 201 and the electronic device 100 may have two electric connection manners.

In some examples, the parts of the fixed sections 201 exposed to the substrate 10 may be connected with a printed circuit board (PCB) or a flexible printed circuit (FPC) of the electronic device 100 through bonding wires.

When the connection contacts 203 make contact with exposed metal connection points of another electronic device, the connection contacts 203 sink towards the second side 102 of the substrate 10 under acting force, the connection contacts 203 transfer the acting force to the free sections 202, since the metal elastic sheets 20 have elasticity, the free sections 202 elastically deform after being subjected to the acting force and provide elasticity to the connection contacts 203, the elasticity makes the connection contacts 203 move towards the first side 101 of the substrate 10, and thus the connection contacts 203 and the exposed metal connection points of another electronic device are kept in contact, which guarantees the stability of a charging process or a data transmission process.

In some examples, the free sections 202 may be constructed in any appropriate way. Alternatively, referring to FIG. 6, the free sections 202 may include first sections 2021 and second sections 2022.

In addition, in practical applications, when the connection contacts 203 do not need to be raised, the free sections 202 do not need to be bent, that is, the first sections 2021 and the second sections 2022 are located at the same horizontal plane.
