Detailed Description

In order to explain the technical content, the objects and the effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.

The utility model discloses the most crucial design lies in: one end of the suction part is turned downwards and extends to form a welding part, the other end of the suction part extends to form an elastic arm in a direction away from the welding part in an inclined mode, the elastic piece is novel in structure, and the deformation space is sufficient.

Referring to fig. 1 to 3, the elastic sheet includes a suction portion 1, a welding portion 2 and an elastic arm 3, one end of the suction portion 1 is turned downward and extends to form the welding portion 2, and the other end of the suction portion 1 extends to form the elastic arm 3 in a direction away from the welding portion 2.

From the above description, the beneficial effects of the present invention are: the elastic sheet has simple and novel structure and low manufacturing cost; the absorption portion that vertical direction overlaps, welding part can reserve sufficient deformation space for the elastic arm, not only can increase the upper limit of the positive force that the shell fragment provided, can also let the shell fragment stably switch on with outside electronic components.

Further, still include kink 5, absorption portion 1 passes through kink 5 and connects elastic arm 3.

From the above description, the bending portion enables the absorbing portion and the elastic arm to be in smooth transition, so as to reduce stress concentration and improve the stability of the elastic sheet structure.

Further, the bending part 5 is lower than the top surface of the suction part 1.

According to the description, the bending part can also be used as a supporting leg to form a contact when the elastic sheet is pressed, so that the working stability of the elastic sheet is improved.

Further, the number of the elastic arms 3 is two, and the two elastic arms 3 are arranged at intervals.

Furthermore, the side surfaces of the two elastic arms 3 close to each other are respectively an arc surface 6, and an installation hole position 7 is formed between the two elastic arms 3.

As can be seen from the above description, due to the existence of the mounting hole, the elastic sheet can be used not only as an electrical connector, but also as a gasket, thereby achieving multiple purposes.

Further, the other end of the suction part 1 is provided with a transition surface 8, and the two arc surfaces 6 are in smooth transition through the transition surface 8.

Furthermore, one end of the welding part 2 close to the elastic arm 3 is provided with a clearance gap 9.

As can be seen from the above description, the avoiding notch can avoid the external fixing piece in the mounting hole position.

Further, the elastic arm 3 is arc-shaped.

As can be seen from the above description, the spring plate is shaped like a horn.

Example one

Referring to fig. 1 to fig. 3, a first embodiment of the present invention is: the elastic sheet comprises a suction part 1, a welding part 2 and an elastic arm 3, wherein one end of the suction part 1 is turned downwards and extends to form the welding part 2, and the other end of the suction part 1 inclines towards the direction far away from the welding part 2 and extends to form the elastic arm 3. The top surface of the suction part 1 is a suction surface so that the elastic sheet can be welded and assembled with an external component (such as a PCB (printed Circuit Board) 4) by using an SMT (surface Mount technology) process; the soldering part 2 is used for soldering with an external member such as a PCB 4. In detail, the welding portion 2 is parallel to the suction portion 1 and the welding portion 2 is located below the suction portion 1. The sucking part 1 and the elastic arm 3 form an obtuse angle structure.

Still include kink 5, absorption portion 1 passes through kink 5 connects elastic arm 3. Preferably, the bent portion 5 is lower than the top surface of the suction portion 1, and the radian corresponding to the bent portion 5 is smaller than pi. When the elastic sheet is pressed, the bottom of the bending part 5 firstly pushes against an external component (such as a PCB 4) to form a contact, so that the elasticity of the elastic sheet is further improved.

The number of the elastic arms 3 is two, and the two elastic arms 3 are arranged at intervals. Optionally, the side surfaces of the two elastic arms 3 close to each other are respectively an arc surface 6, a mounting hole 7 is formed between the two elastic arms 3, and preferably, the elastic arms 3 are arc-shaped. In this embodiment, the other end of the suction portion 1 is provided with a transition surface 8, and the two arc surfaces 6 are in smooth transition through the transition surface 8. More specifically, the transition surface 8 and the two arc surfaces 6 are located on the same circumferential surface. The spring plate of this embodiment can be directly used as a planar gasket (for example, a bolt is inserted into the mounting hole 7, so that the spring plate becomes a bolt gasket). The resilient arm 3 can be pressed flat against the top surface of the suction part 1 to provide a sufficient positive force to increase the contact stability. In addition, when the elastic sheet is used as a plane gasket, an auxiliary part of conductive foam does not need to be arranged, and cost is saved.

In summary, the elastic sheet provided by the utility model has simple and novel structure and low manufacturing cost; can provide larger positive force, and has good structure and working stability; the elastic sheet can be used as an electric connector and also can be used as a gasket, so that the multifunctional electric connector is realized.
