Description
Technical field
Buzzer technical field is the utility model is related to, specially a kind of new buzzer guide pin.
Background technology
Existing buzzer structure is that piezo is set in buzzer housing, and two guide pins are installed below in piezo, its
Middle guide pin is generally T-shaped structure, and the guide pin of T-shaped is welded and fixed in assist side by electric iron.When making buzzer, due to
The guide pin of T-shaped is needed by electric iron welding in the circuit board, and wiring board is thin, and high temperature scolding tin easily burns, and is welded on
The stability of guide pin on wiring board is poor；In addition, buzzer guide pin low intensity of the prior art, is easily broken off, service life
It is short.
Utility model content
The purpose of this utility model is to provide a kind of new buzzer guide pin, to solve what is proposed in above-mentioned background technology
Problem.
To achieve the above object, the utility model provides following technical scheme：A kind of new buzzer guide pin, including lead
Pin body, the guide pin body include guide pin end, guide pin stalk portion and guide pin head, and the guide pin stalk portion is arranged on guide pin body
Middle part, the guide pin stalk portion side are provided with the groove of an at least ring cross-section semicircular in shape, and the guide pin end is welded with blade, institute
State guide pin head and be welded with contact chip.
Preferably, in addition to reinforcement, the reinforcement is welded between guide pin end and guide pin stalk portion, and the reinforcement
Muscle and blade contact.
Preferably, the blade sets 3-4 pieces.
Preferably, the distance between the blade and guide pin body termination are 1mm-1.5mm.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple in construction, convenient welding,
Guide pin end is welded with 3-4 piece blades, it is possible to increase firm welding, can prevent wiring board from burning；In addition in guide pin end
Reinforcement, and reinforcement and blade contact are welded between guide pin stalk portion, it is possible to increase guide pin bulk strength, it is not easy to break,
Service life is grown.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out

Referring to Fig. 1, the utility model provides a kind of technical scheme：A kind of new buzzer guide pin, including guide pin body
1, the guide pin body 1 includes guide pin end 2, guide pin stalk portion 3 and guide pin head 4, and the guide pin stalk portion 3 is arranged on guide pin body
1 middle part, the side of guide pin stalk portion 3 are provided with the groove 5 of an at least ring cross-section semicircular in shape, and the guide pin end 2 is welded with leaf
Piece 6, it is 1mm-1.5mm that blade 6, which sets the distance between 3-4 pieces blade 6 and the termination of guide pin body 1,；Weld on the guide pin head 4
There is contact chip 7.
In the present embodiment, in addition to reinforcement 8, the reinforcement 8 are welded between guide pin end 2 and guide pin stalk portion 3, and
The reinforcement 8 contacts with blade 6.
The utility model is simple in construction, convenient welding, 3-4 piece blades is welded with guide pin end, it is possible to increase welding jail
Solidity, it can prevent wiring board from burning；Reinforcement, and reinforcement and leaf are welded between guide pin end and guide pin stalk portion in addition
Piece contacts, it is possible to increase guide pin bulk strength, not easy to break, service life length.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
