Description

Elastic sheet type electric contact structure of optical filter switcher and camera device

Technical Field

The utility model relates to a camera technical field, in particular to shell fragment formula electrical contact structure and camera device of light filter switch.

Background

In the prior art, the filter switcher is connected with the client circuit board by a lead wire with a lead connector, however, the lead wire mode has the following disadvantages:

(1) because the wire has the joint, a male seat is required to be punched on the circuit board of the client side, and the female head of the wire is inserted, so that the cost of the male connector is also required for the client side besides the punching cost, and the cost of one more wire is also required;

(2) the client often troubles how the wire is stored in the machine due to the length of the wire, and sometimes the wire is broken by the factor of the wire in assembling the shell, so the wire lengths with different requirements are generated on the requirements of different clients, and the problem of material preparation is disturbed due to the fact that a manufacturer distinguishes multiple machines for the same type of products due to the factor of the wire length, and the wire length is different singly;

(3) at present, a plurality of imitation factories are full of wire connectors in the market, because the connectors need to be matched by a male seat and a female seat, the connectors are led by Japanese-series Momo-type large brands in the early stage, and later, because various imitation factories exist, the problem that the connectors cannot be electrified after being plugged once the connectors are not matched is caused;

(4) the mode that utilizes the lead wire to be qualified for the next round of competitions is difficult to automatic, or automatic equipment cost is higher that says so, because the switch is with the lead bonding, the lead wire is the bending bend, does not design the machine clamp to get in automation well and carries out automatic weld.

SUMMERY OF THE UTILITY MODEL

The utility model provides a shell fragment formula electrical contact structure and camera device of light filter switch to solve at least one above-mentioned technical problem.

In order to solve the above problem, as an aspect of the present invention, there is provided a spring sheet type electrical contact structure of a light filter switch, including: the optical filter comprises a lens mount, a spring plate electrode, a coil frame and an optical filter sliding frame, wherein the coil is wound on the coil frame, an iron core is arranged inside the coil frame, the iron core drives the optical filter sliding frame to move relative to the lens mount so as to realize optical filter switching, the spring plate electrode is fixedly connected with one end of the coil frame, one end of the spring plate electrode is electrically connected with the coil, and the other end of the spring plate electrode is bent to form an elastic contact part which is in elastic contact with a contact point on a circuit board at the bent part.

Preferably, the plurality of dome electrodes are arranged in parallel.

Preferably, the other end of the dome electrode is bent back in a reverse direction to form the elastic contact portion.

Preferably, the elastic sheet electrode is fixedly connected with the coil rack in an injection molding mode.

The utility model also provides a camera device, shell fragment formula electrical contact structure including foretell light filter switch.

By adopting the technical scheme, the utility model can save a male seat of the connector needing to be punched on the board, thereby reducing the cost; when the switcher is assembled, the screws can be directly assembled only by contraposition assembly, and the assembly is completed after the screws are assembled, so that the electric conduction is realized, the cost of assembly working hours is reduced, and the assembly working hours are saved; the elastic sheet electrode arranged at the bottom of the switcher is beneficial to being in direct elastic contact with a circuit board of a client, the structure appearance and the size are integral and clean, and the wire coil is not required to be laid on the appearance.

Detailed Description

The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

An aspect of the utility model provides an elastic sheet formula electrical contact structure of light filter switch, include: lens mount 1, shell fragment electrode 2, coil 3, coil former 4 and light filter carriage 5, coil 3 twines on the coil former 4, the inside of coil former 4 is provided with the iron core, iron core 8 passes through swing arm 9 drive the light filter carriage 5 is relative lens mount 1 motion is in order to realize the light filter and switch, and is a plurality of the one end of shell fragment electrode 2 with one side fixed connection of coil former 4, shell fragment electrode 2 the one end with coil 3 electricity is connected, the other end of shell fragment electrode 2 is buckled and is being buckled the department and form the elastic contact portion 7 with contact point 11 elastic contact on the circuit board 6.

When the elastic sheet type electric contact structure is used, the elastic sheet type electrode 2 is utilized to form the elastic sheet type electric contact structure, and when the elastic sheet type electric contact structure is installed, the elastic sheet type electrode 2 faces the contact point 11 on the client circuit board and is pressed tightly, so that the elastic force of the elastic sheet type electrode 2 is utilized to enable the elastic sheet type electrode 2 to be in conductive contact with the contact point 11.
