Embodiment
Make further more detailed description to the technical solution of the utility model with reference to embodiment.Obviously,
Described embodiment is only part of the embodiment of the present utility model, rather than whole embodiments.It is new based on this practicality
Embodiment in type, the every other reality that those of ordinary skill in the art are obtained on the premise of creative work is not made
Example is applied, should all belong to the scope of the utility model protection.
Refering to Fig. 1-2, Fig. 1 is the vertical view and elevational schematic view of a kind of contact type charger provided by the utility model, Fig. 2
It is a kind of configuration schematic diagram of contact type charger provided by the utility model.The charger 100 includes shell 110, set
The circuit board 120 being placed in shell and the positive and negative electrode 130 being arranged on circuit board.
Shell 110 can be formed in one, or fastened and formed by two parts.Preferably, the shell fastened using two parts
110, the two is threadedly connected, or by setting buckle to be attached at the edge that two parts connect.Circuit board 120
It is fixedly installed on inside shell 100.Complete charging circuit is provided with the circuit board 120, will be outer by a power transformer
The alternating current of boundary's connection imports circuit board, is operated by the transformation of power transformer, rectification and filtering etc., eventually through positive negative electricity
The voltage volt degree that pole output is specified, such as 3.5V.Second through hole 112 is set on shell 110, and the input interface of power transformer is from
Two through holes 112 stretch out, and circuit board 120 and extraneous alternating current is attached by wire.Two are vertically arranged on circuit board 120
Individual electrode, as spring electrode 130, the positive and negative electrode 131 of spring electrode 130 are in the form of a column, and are connected to circuit by spring 132
Plate 120, and spring 132 is vertical with circuit board 120.Tie point of the spring 132 on circuit board 120 is the electricity of circuit board 120
Output point is pressed, after spring 132 and positive and negative electrode 131 are connected into circuit board 120, finally export and specifies from positive and negative electrode 131
Fu Du magnitude of voltage.Meanwhile first through hole 111 is set on shell 110, first through hole 111 has two, makes spring electrode respectively
130 positive and negative electrode 131 stretches out housing exterior.The length of positive and negative electrode 131 is set by the thickness of shell 110, bullet is worked as in guarantee
Spring 132 is compressed to most in short-term, and positive and negative electrode 131 still can reach housing exterior inside shell 110.
In the present embodiment, the surface of first through hole 111 is set to form a plane, first through hole 111 on shell 110
Contacted positioned at the center of the plane or by paracentral position, the charging position of charging equipment and positive and negative electrode 131, can should
Charging equipment is positioned over the surface for setting first through hole 111.After charging complete, by the charging position of charging equipment with it is positive and negative
Electrode 131 departs from.Connection during to consolidate charging between the electrode of charger and electrical equipment to be charged, bag is set generally on shell
The annular projection edge 114 of positive and negative electrode 131 is enclosed, the one of which of positive and negative electrode 131 is arranged in annular projection edge 114
Heart position.It is the charging structure corresponding to spring electrode 130 in the charging electrode of electrical equipment to be charged, such as in the utility model
Shown in Fig. 3, including a conductive pole 101 and a conducting ring 102, conductive pole 101 are arranged in the annular space of conducting ring 102, the two
The circuit board of electrical equipment to be charged is connected to, and the two is not contacted.During charging, ring will be arranged on conductive pole 101 and charger 100
The spring electrode contact of the center of shape raised brim 114, conducting ring 102 contacts with another spring electrode, and realizes charging.Together
When, for convenience of electrical equipment to be charged, when charging, placement consolidates, annular for center of circle setting one with conductive pole 101 on band charging electrical equipment
Groove, the annular groove coordinate with annular projection edge 114, annular projection edge 114 are placed in annular groove during charging,
It is easy to fix the position of electrical equipment to be charged in charging.
Further, in addition to base 140.Base 140 is used for load-carrying covering 110, and whole contact type charger 100 is placed
Cause to leak electricity in base 140, preventing from contacting with water or other liquid, at the same can ensure set first through hole 111 surface with
Plane-parallel.
Further, third through-hole 113 is set on shell 110, an indicator lamp (not shown) is set on circuit board 120, is indicated
Lamp is reached outside shell 110 by third through-hole 113, and the energization situation of circuit board 120 is observed by indicator lamp.
Contact type charger of the present utility model can meet the charging of the different product of charging modes of the same race, by contact into
Row charging, avoids the situation of charging plug, adds the service life of charger, while can prevent potential safety hazard.
