Abstract
The utility model relates to an electromagnetic welding-free buzzer, which comprises a buzzer shell, connecting terminals and contact pins, wherein the connecting terminals and the contact pins are symmetrically arranged on the buzzer shell; the connecting terminal is L-shaped, and the inner side wall of one end of the connecting terminal is connected with the side wall of the shell of the buzzer; the upper end face of the other end of the connecting terminal is positioned below the bottom of the buzzer shell and is not contacted with the bottom of the buzzer shell; the contact pin is arranged below the lower end face of the other end of the connecting terminal; the contact pin comprises a fixed rod, a movable rod sleeved in the fixed rod and a spring sleeved on the movable rod; when the buzzer shell moves downwards, the movable rod abuts against the lower end face of the connecting terminal and bends the connecting terminal, and the connecting terminal is in contact with the buzzer shell; thereby take place relative motion through bee calling organ casing and contact pilotage and realize the pronunciation of bee calling organ to realize exempting from of bee calling organ to weld, thereby conveniently dismantle from the circuit board.
Description
Technical Field
The utility model relates to a buzzer specifically is an electromagnetic type exempts from to weld buzzer.
Background
The buzzer is an electronic buzzer with an integrated structure, adopts direct current voltage for power supply, and is widely applied to electronic products such as computers, printers, copiers, alarms, electronic toys, automobile electronic equipment, telephones, timers and the like as a sounding device. The patch type electromagnetic buzzer is often connected with the circuit board through a connecting terminal of a shell at the bottom of the buzzer to provide electric energy for the buzzer; the conventional patch type electromagnetic buzzer is usually welded on a circuit board, and the buzzer is difficult to take down when the circuit board is damaged; how to realize the welding-free of the buzzer so as to be convenient to disassemble from the circuit board becomes a problem which needs to be solved urgently by the company.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: how to realize the welding-free of the buzzer, thereby being convenient to be detached from the circuit board.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model relates to an electromagnetic welding-free buzzer, which comprises a buzzer shell, connecting terminals and contact pins, wherein the connecting terminals and the contact pins are symmetrically arranged on the buzzer shell;
the connecting terminal is L-shaped, and the inner side wall of one end of the connecting terminal is connected with the side wall of the shell of the buzzer;
the upper end face of the other end of the connecting terminal is positioned below the bottom of the shell of the buzzer and is not contacted with the bottom of the shell of the buzzer;
the cross section of the connecting terminal is L-shaped, and the L-shaped function is to fix the connecting terminal on the side wall of the shell of the buzzer, prevent the connecting terminal from contacting with a contact of an internal component of the buzzer and prevent the sounding of the buzzer.
A contact pin is arranged below the lower end face of the other end of the connecting terminal;
the contact pin has the function of moving relative to the buzzer shell, the end part of the contact pin is abutted against the lower end face of the connecting terminal to bend the connecting terminal, one end of the connecting terminal is in contact with the buzzer shell, and components in the buzzer shell are electrified and sounded.
The contact pin comprises a fixed rod, a movable rod sleeved in the fixed rod and a spring sleeved on the movable rod;
when the buzzer shell descends, the movable rod abuts against the lower end face of the connecting terminal and bends the connecting terminal, and the connecting terminal is contacted with the buzzer shell;
the fixed rod is a fixed rod, the movable rod is sleeved in the fixed rod and moves up and down relative to the fixed rod, and the movable rod moves and abuts against the end part of the connecting terminal; the spring functions to provide a directional force when the contact pin is pressed against the connection terminal, and to return the movable lever.
The utility model has the advantages that: the utility model relates to an electromagnetic type exempts from to weld bee calling organ takes place relative motion through bee calling organ casing and contact pilotage and realizes the pronunciation of bee calling organ to realize exempting from of bee calling organ and weld, thereby the convenience is dismantled from the circuit board.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention;
