Abstract
A kind of duplex round chip DC adaptor, comprises positioning sleeve, outer tube and interior pipe; Described outer tube sleeve is located at the outside of interior pipe, is provided with insulator between outer tube and interior pipe; Described positioning sleeve is sheathed on the outer rim in the middle part of described outer tube; It is characterized in that: the tube wall at the two ends of described interior pipe is all at least provided with two panels shell fragment, and each described shell fragment is evenly arranged in the circumference of inner pipe wall.By arranging multiple shell fragment on inner pipe, interior pipe can be connected with the center pin of direct current jack at multiple position (namely circumference is connected), even if the environment of therefore work has vibrations also can not change the connection status of Nei Guanhe center pin, then ensure that the reliability that DC adaptor connects in direct current jack.Compared to existing technologies, the utility model can meet the switching of limited distance between LED lamp tube, can ensure again the stability contacted.
Description
Technical field
The utility model relates to a kind of DC adaptor, is specifically related to a kind of duplex round chip DC adaptor.This duplex round chip DC adaptor is for two adjacent LED lamp tube of connecting.
Background technology
Double end DC adaptor is a kind of small-sized electrical connection device, and its effect is for two adjacent LED lamp tube of connecting, and the direct current jack be equipped with in described LED lamp tube end realizes the transmission transport of power supply.
As shown in Figure 1, existing double end DC adaptor comprises positioning sleeve 1, outer tube 2 and interior pipe 3.Wherein, described outer tube 2 is sheathed on the outside of interior pipe 3, is provided with insulator 4 between outer tube 2 and interior pipe 3.Described positioning sleeve 1 is sheathed on the outer rim in the middle part of described outer tube 2, and the material of this positioning sleeve 1 is the composition of nylon and glass.Design whereby, when described double end DC adaptor inserts in a direct current jack of LED lamp tube end, described outer tube 2 will coordinate with the inwall of described direct current jack (this inwall is provided with electroconductive elastic sheet), and is electrically connected with it; Described interior pipe 3 is sheathed on a center pin of this direct current jack, is electrically connected with it.Although this existing double end DC adaptor solves the switching problem of limited distance between LED lamp tube, but find after Long-Time Service to have the following disadvantages: the operation principle due to this existing double end DC adaptor is the center pin diameter by being arranged by the internal diameter of described interior pipe slightly larger than direct current jack, again by the electroconductive elastic sheet effect on described direct current jack inwall, inner tube wall side and the described center pin of adapter described in trend carry out linear contact lay to connect, and this kind of structural design when working under some vibration environment, have certain probability to connect because vibration causes described Nei Guanyu center pin to depart from, thus cause the generation of instant contact unfavorable condition.
Therefore, how to solve the problem of the connection reliability deficiency that above-mentioned prior art exists, just become the problem that the utility model will be studied.
Summary of the invention
The utility model provides a kind of duplex round chip DC adaptor, its object is to the problem solving the connection reliability deficiency that existing double end DC adaptor exists.
For achieving the above object, the technical solution adopted in the utility model is: a kind of duplex round chip DC adaptor, comprises positioning sleeve, outer tube and interior pipe; Described outer tube sleeve is located at the outside of interior pipe, is provided with insulator between outer tube and interior pipe; Described positioning sleeve is sheathed on the outer rim in the middle part of described outer tube; The tube wall at the two ends of described interior pipe is all at least provided with two panels shell fragment, and each described shell fragment is evenly arranged in the circumference of inner pipe wall.
Related content in technique scheme is explained as follows:
1., in such scheme, the setting of described shell fragment, makes described interior pipe can connect with the center pin of direct current jack at multiple position (namely circumference is connected), even if the environment of therefore work has vibrations also can not change the connection status of described Nei Guanhe center pin.
2., in such scheme, also comprise a copper ring; In addition, described outer tube is two-part structure; Described copper ring is sheathed on the junction of two sections of outer tubes, plays the effect connecting these two sections of outer tubes; Described positioning sleeve is sheathed on the outer rim of described copper ring.Designed by said structure, will the assembling of the utility model DC connector be convenient to.
Operation principle of the present utility model and advantage as follows:
A kind of duplex round chip of the utility model DC adaptor, by arranging multiple shell fragment on inner pipe, interior pipe can be connected with the center pin of direct current jack at multiple position (namely circumference is connected), even if the environment of therefore work has vibrations also can not change the connection status of Nei Guanhe center pin, then ensure that the reliability that DC adaptor connects in direct current jack.Compared to existing technologies, the utility model can meet the switching of limited distance between LED lamp tube, can ensure again the stability contacted.
