Abstract

The utility model discloses a DC power supply connector for a mobile phone. In order to provide a circuit connector which has the advantages that the manufacture is easy and the bad contact of a plug of a charger and a jack of the mobile phone can be avoided, the utility model is provided. The utility model comprises an insulating cement core, an internal terminal and an external sleeve pipe. A rectangular inserting rod which passes to a T-shaped groove on the bottom end of the insulating cement core and arranged on the side edge is arranged on the insulating cement core; the external sleeve pipe is a metal pipe body with a rectangular cross section; the internal terminal is inserted in the T-shaped groove of the insulating cement core and the external end is exposed on the side edge at the front end of a short inserting rod of the insulating cement core; the external sleeve pipe is sheathed out of the rectangular inserting rod.

Description

Mobile phone DC power supply connector

The utility model belongs to line connector, particularly a kind of mobile phone DC power supply connector.

If general mobile phone be will charge the time, the direct current plug of charger must be inserted on the fuselage the direct current jack, can charge.

And the direct current jack on the known mobile phone is shaped as circle, so the dc power plug on the charger also is circular.So because of, circular section configuration is rotated easily, and the shape of proper circle is in actual manufacture process and can not make and draw, so this dc power plug is easy to generate the situation of loose contact when being inserted into mobile phone direct current jack.

The purpose of this utility model provides a kind of easy to manufacture, mobile phone DC power supply connector of avoiding Charger (portable round) and the loose contact of mobile phone electric jack.

The utility model comprises the insulating cement heart, inner terminal and outer tube; Insulating cement has the rectangle inserted link in the heart, and is provided with the T-slot that passes to insulating cement heart bottom at rectangle inserted link side; Outer tube is the metal body of rectangular section; Inner subsystem is inserted in the T-slot of the insulating cement heart, and its outer end is emerging in the front end side of insulating cement heart rectangle inserted link; The overcoat piping is sleeved on outside the rectangle inserted link.

Wherein:

The and arranged on left and right sides of rectangle inserted link bottom is respectively equipped with to the limit; The inner and arranged on left and right sides of outer tube be respectively equipped with rectangle inserted link bottom and arranged on left and right sides support the limit corresponding and against interior curved reverse lug; The inner and arranged on left and right sides lug that is sleeved on the outer outer tube of rectangle inserted link is resisted against supporting on the limit of rectangle inserted link bottom and arranged on left and right sides.

Because the utility model comprises the insulating cement heart, inner terminal and outer tube; Insulating cement has the rectangle inserted link that side is provided with the T-slot that passes to insulating cement heart bottom in the heart; Outer tube is the metal body of rectangular section; Inner subsystem is inserted in the T-slot of the insulating cement heart, and its outer end is emerging in the front end side of insulating cement heart rectangle inserted link; The overcoat piping is sleeved on outside the rectangle inserted link.Be inserted into because of inner subsystem in the T-slot of the insulating cement heart, avoid inner terminal generation warpage and keep straight shape, when it is inserted in the Direct current power source socket of mobile phone, it is closely contacted with corresponding contact, to avoid producing the situation of loose contact, not only easy to manufacture, and avoid Charger (portable round) and the loose contact of mobile phone electric jack, thus reach the purpose of this utility model.

Fig. 2, be the utility model decomposition texture schematic isometric.

Fig. 3, be the utility model structural representation cutaway view.

Fig. 4, be A-A cutaway view among Fig. 3.

Below in conjunction with accompanying drawing the utility model is further elaborated.

As Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises the insulating cement heart 1, inner terminal 2 and outer tube 3.

Have rectangle inserted link 11 on the insulating cement heart 1, and be provided with T-slot 11a at rectangle inserted link 11 sides, and make T-slot 11a pass to the bottom of the insulating cement heart 1, the and arranged on left and right sides in rectangle inserted link 11 bottoms is respectively equipped with to the limit 12.

Outer tube 3 is the metal body of rectangular section, its inner and arranged on left and right sides be respectively equipped with rectangle inserted link 11 bottom and arranged on left and right sides support limit 12 corresponding and against interior curved reverse lug 31.

As shown in Figure 3, Figure 4, inner terminal 2 is to be inserted in the T-slot 11a of the insulating cement heart 1, and its outer end is emerging in the front end side of the insulating cement heart 1 rectangle inserted link 11; Outer tube 3 is to be sleeved on outside the rectangle inserted link 11, and the lug 31 of its inner and arranged on left and right sides is resisted against supporting on the limit 12, so that outer tube 3 is fixed on outside the rectangle inserted link 11 of rectangle inserted link 11 bottom and arranged on left and right sides.

By said structure,, avoid inner terminal 2 generation warpages and keep straight shape because of inner terminal 2 is to be inserted in the T-slot 11a of the insulating cement heart 1 rectangle inserted link 11.As shown in Figure 1, when it is inserted in the Direct current power source socket 41 of mobile phone 4, it is closely contacted, with corresponding contact to avoid producing the situation of loose contact.

Moreover, the inner interior curved reverse lugs 31 of going up tools of outer tube 3, therefore, when outer tube 3 is sleeved on the rectangle inserted link 11 of the insulating cement heart 1, lug 31 is resisted against supporting on the limit 12 of rectangle inserted link 11, makes this outer tube 3 be able to firm encapsulation outside the rectangle inserted link 11 of the insulating cement heart 1.

Outer tube 3 is the metal body of rectangular section again, when it is inserted in the Direct current power source socket 41 of mobile phone 4, can avoid producing rotation, and outer tube 3 is closely contacted with corresponding contact, to avoid producing the situation of loose contact.
