Description
Technical field
The utility model relates to a kind of locating terminal, especially relates to a kind of easy-to-dismount locating terminal, belongs to the communications field.
Background technology
General with direct current (also useful asymmetrical alternating current electric current or pulse current) charging.Under the different situations, adopt the combined charging of different charging methods such as constant current charge, constant voltage charging, floating charge, trickle charge, boost charge or these methods etc.Charger has a lot, such as the test of lead acid batteries charger, valve-control sealed lead acid battery and monitoring, electricity charger for Ni-Cd battery, nickel-metal hydride battery charger, charger for lithium ion battery, portable electric appts charger for lithium ion battery, lithium ionic battery protection circuit multifunctional charger, electromobile battery charger, Che Chong etc.The fixing of traditional charging terminal all is to adopt screw to fix, namely be to make screw hole at charging terminal and mainboard, this process is loaded down with trivial details, careless slightly, just easy overall structure on charging terminal has caused impact, in use the whole stress balance of charging terminal is destroyed, when running into bump, the screwed hole place is easy to crack, all bother very much in the installation and removal process, and screw when using one section after, easily produce the phenomenons such as corrosion or stripped thread, caused very large inconvenience for maintenance personal's dismounting.
The utility model content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, a kind of easy-to-dismount locating terminal is provided, this locating terminal is simple in structure, utilize the cooperation of reference column and location hole, cargo handling process is all very convenient, has reduced maintenance personal's lay day, has improved production efficiency, avoided simultaneously locating terminal inside is produced the imagination such as leak, guaranteed the accuracy of installing.
The purpose of this utility model is achieved through the following technical solutions: a kind of easy-to-dismount locating terminal, comprise mainboard and charging terminal, be provided with reference column on the described charging terminal, be provided with location hole on the described mainboard, described reference column is arranged in the location hole, is provided with pad between described location hole and the reference column.
Described pad is arranged in the location hole, and contacts with the bottom of location hole.
Described location hole diameter is greater than the diameter of reference column.The assurance reference column can be put into location hole exactly, guarantees effectively fixing.
The quantity of described reference column is two, is separately positioned on the two ends of charging terminal.
The quantity of described location hole is two, and its position is corresponding with the position of reference column.Adopt two-way location, can be so that the location be more firm.
The bottom of described charging terminal contacts with mainboard.The bottom of charging terminal contacts with mainboard, has fixed in the vertical charging terminal.
In sum, the beneficial effects of the utility model are: this locating terminal is simple in structure, utilize the cooperation of reference column and location hole, cargo handling process is all very convenient, reduced maintenance personal's lay day, improve production efficiency, avoided simultaneously locating terminal inside is produced the imagination such as leak, guaranteed the accuracy of installing.
Description of drawings
Fig. 1 is structural representation of the present utility model;

Mark and corresponding parts title in the accompanying drawing: 1-mainboard; 2-charging terminal; 3-reference column; 4-location hole; 5-pad.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but execution mode of the present utility model is not limited only to this.
Embodiment 1:
Such as Fig. 1, Fig. 2, shown in Figure 3, a kind of easy-to-dismount locating terminal comprises mainboard 1 and charging terminal 2, is provided with reference column 3 on the described charging terminal 2, is provided with location hole 4 on the described mainboard 1, and described reference column 3 is arranged in the location hole 4.Described pad 5 is arranged in the location hole 4, and contacts with the bottom of location hole 4.Described location hole 4 diameters are greater than the diameter of reference column 3.The diameter of location hole 4 can guarantee that greater than the diameter of reference column 3 reference column 3 is placed in the location hole 4 smoothly, so that the location is more accurate.
The quantity of described reference column 3 is two, is separately positioned on the two ends of charging terminal 2.Two reference columns 3 are separately positioned on the two ends of charging terminal 2,, can not come off while stressed more balance at work so that charging terminal 2 is more firm.
The quantity of described location hole 4 is two, and its position is corresponding with the position of reference column 3.The position that guarantees reference column 3 and location hole 4 is corresponding.The bottom of described charging terminal 2 contacts with mainboard 1.The bottom of charging terminal 2 contacts with mainboard 1, has fixed in the vertical charging terminal 2.
Adopt two reference columns 3 to add the contact plane and charging terminal 2 is done spacing in three directions, guarantee the positioning accuracy before the charging terminal 2SMT.
SMT is surface installation technique (surface mounting technology), is most popular a kind of technology and technique in the present Electronic Assemblies industry.
Embodiment 2:
The structure of the present embodiment and embodiment 1 is basic identical, and its difference only is: be provided with pad 5 between described location hole 4 and the reference column 3.By reference column 3 is placed in the location hole 4, can exactly charging terminal 2 be installed on the mainboard 1, be fixed rapidly.Locating terminal in use for some time, reference column 3 easily and the bottoms of location hole 4 occur bondingly, cause dismounting difficult, pad 5 is set after, can avoid occurring this situation.
Take aforesaid way, just can realize preferably the utility model.
