Abstract
The utility model relates to a buzzer guiding needle. According to the utility model, problems that the stability of a T-shaped guiding needle is poor and a circuit board is easily damaged due to tin soldering of the T-shaped guiding needle and the circuit board are solved. The buzzer guiding needle is in a cross and cylinder structure, and comprises a cylindrical guiding needle body, a clamping ring is arranged at a position close to the end head of one end of the cylindrical guiding needle body, the diameter of the cylindrical guiding needle body is 0.59-0.61 mm, the diameter of the clamping ring is 1.45-1.155 mm, and the distance between the clamping ring and the end head of the end of the cylindrical guiding needle body is 0.6-1 mm. The buzzer guiding needle is of simple and stable structure and low cost, and by employing the buzzer guiding needle, burning damage to the circuit board can be effectively reduced.
Description
Technical field
the utility model relates to a kind of hummer guide pin.
Background technology
existing hummer structure is, buzzing sheet is set in hummer housing, two guide pins is installed below buzzing sheet, and wherein guide pin is generally T shape structure, and the guide pin of T shape is welded and fixed in the circuit board by electric soldering iron.When making hummer, because the guide pin of T shape need to weld in the circuit board by electric soldering iron, and wiring board is thin, and high temperature scolding tin easily burns, and the poor stability of welding guide pin in the circuit board.
in order to solve existing T shape guide pin and wiring board welding, easily cause the problem of above-mentioned defect, be necessary to research and develop a kind of hummer guide pin of new structure.
Summary of the invention
this practical object is in order to solve T shape guide pin and wiring board scolding tin, easily damaged line plate, and the problem of poor stability, and a kind of hummer guide pin is provided.
the utility model is achieved through the following technical solutions:
a kind of hummer guide pin, for cruciform column structure, comprise cylindrical guide pin main body, in cylindrical guide pin main body, near the position of termination, one end, be provided with snap ring, the diameter of described cylindrical guide pin main body is 0.59-0.61mm, the diameter of described snap ring is 1.45-1.155mm, and described snap ring is located at the position near cylindrical guide pin main body one end termination 0.6-1mm.
while making hummer, preset in the circuit board jack, jack is inserted in the one end that cylindrical guide pin main body is arranged to snap ring, can avoid like this welding scaling loss wiring board, and Stability Analysis of Structures.
the utility model is simple in structure, and cost is low, can effectively reduce the scaling loss of wiring board, and Stability Analysis of Structures.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model;
fig. 2 is vertical view of the present utility model;
in figure: the cylindrical guide pin main body of 1-, 2-snap ring.
Embodiment
below in conjunction with accompanying drawing, the utility model is described further.
a kind of hummer guide pin as shown in Figure 1, 2, for cruciform column structure, comprise cylindrical guide pin main body 1, in cylindrical guide pin main body 1, near the position of termination, one end, be provided with snap ring 2, the diameter of described cylindrical guide pin main body 1 is 0.59-0.61mm, the diameter of described snap ring 2 is 1.45-1.155mm, and described snap ring 2 is located at the position near cylindrical guide pin main body 1 termination, one end 0.6-1mm.
