Description

The modified model direct current electric connector

The utility model relates to electric coupler, refers to a kind of attaching plug with plug and socket especially, and the positive pole of socket and plug is connected respectively with negative pole, to reduce the modified model direct current electric connector of manufacturing cost, the raising market competitiveness.

In the prior art, general portable electrical equipment as laptop computer, mobile phone, walkman etc., uses battery usually, when using up as if the electric energy of battery, must charge with charger or power supply unit.

And portable electrical equipment has a supply socket, the connecting line of charger or power supply unit has an attaching plug, need the attaching plug of charger or power supply unit is inserted in the supply socket of portable electrical equipment, and, can charge or select for use AC power directly to use portable electrical equipment with the power line grafting AC power of charger or power supply unit.

Some portable electrical equipment uses identical voltage again, and when a plurality of portable electrical equipment need use a charger or power supply unit simultaneously, because of the connecting line of charger or power supply unit only has a plug, so can't use a charger or power supply unit jointly; Thereby install a socket additional at the rear of plug, make plug be inserted into the seat of portable electrical equipment after, the socket at this plug rear need become a supply socket, uses for other portable electrical equipment socket power.

Referring to Fig. 3, be the portable electrical equipment in the prior art, it has plug a, socket b and power line c, plug a is made of an outer sleeve a1 and inner sleeve a2, between outer sleeve a1 and inner sleeve a2, be provided with an insulating barrier a3, this insulating barrier a3 is provided with a socket a31, the plug-in mounting one guide card d of socket a31 place makes guide card d contact inner sleeve a2; Socket b is made of a cylinder base b1 and center latch b2, is set with a tubular shell fragment b3 in cylinder base b1; The inner sleeve a2 of plug a has an inserted terminal a21 again, and the center latch b2 of this socket b has a spliced eye b21, and the inserted terminal a21 plug-in mounting of inner sleeve a2 is fixed in the spliced eye b21 of center latch b2, and inner sleeve a2 and center latch b2 are linked into an integrated entity; The outer sleeve a1 of plug a is connected on the cylinder base b1 of socket b by lead e again, and outer sleeve a1 is connected with cylinder base b1; The anodal c1 of one power line c is connected with above-mentioned guide card d, and negative pole c2 is connected with the cylinder base b1 of socket b, and making the inner sleeve a2 of plug a and the center latch b2 of socket b is the positive pole of power supply, and the cylinder base b1 of the outer sleeve a1 of plug a and socket b is the negative pole of power supply; The insulator f of one injection molding outside integral body again.

But the center latch b2 of the inner sleeve a2 of plug a and socket b is two independently members, must make respectively, assembles connection again, so comparatively trouble is inconvenient on making and assembling, and the manufacturing cost height.

The outer sleeve a1 of plug a is connected on the cylinder base b1 of socket b by lead e again, must connect by welding manner, so equally comparatively trouble is inconvenient in assembling, and the manufacturing cost height.

The purpose of this utility model is: at the problems referred to above, provide a kind of and be convenient to make and assembling, to reduce the modified model direct current electric connector of manufacturing cost, the raising market competitiveness.

The purpose of this utility model is achieved in that a kind of modified model direct current electric connector, and it is made up of plug and socket, is formed with an insulation ectosome at plug and socket; Plug is made of outer sleeve and inner sleeve, is provided with an insulating barrier between outer sleeve and inner sleeve, and this insulating barrier is provided with a socket, plug-in mounting one guide card in the socket, and this guide card is connected with the inner sleeve contact; And socket is made of a cylinder base and center latch, is set with a tubular shell fragment in cylinder base, and the outer sleeve of plug is connected with the cylinder base of socket, and the inner sleeve of plug is connected with the center latch of socket; The positive pole of one power line is connected on the above-mentioned guide card, and negative pole is connected on the cylinder base of socket, it is characterized in that: the center latch of above-mentioned socket and the inner sleeve of plug are formed in one, tubular shell fragment the inner in the cylinder base of socket is provided with a lug, this lug is welded on the outer sleeve surface of plug, and the positive and negative electrode of socket and plug is connected as a single entity separately.

The utility model further specifies by the following drawings and embodiment:

Fig. 1, be stereogram of the present utility model.

Fig. 2, be assembling view of the present utility model

Fig. 3, be the assembling view of prior art.

Referring to Fig. 1,2, a kind of modified model direct current electric connector, it is made up of plug 1 and socket 2, and plug 1 is formed with an insulation ectosome 10 with socket 2; This plug 1 is made of outer sleeve 11 and inner sleeve 12, is provided with an insulating barrier 13 between outer sleeve 11 and inner sleeve 12, and this insulating barrier 13 is provided with a socket 131, and plug-in mounting one guide card 14 in the socket 131 makes guide card 14 be connected with inner sleeve 12 contacts; And socket 2 is made of a cylinder base 21 and center latch 22, is set with a tubular shell fragment 23 in cylinder base 21, and the outer sleeve 11 of plug 1 is connected with the cylinder base 21 of socket 2, and the inner sleeve 12 of plug 1 is connected with the center latch 22 of socket 2; The positive pole 31 of one power line 3 is connected with guide card 14, and negative pole 32 is connected with the cylinder base 21 of socket 2; The center latch 22 of this socket 2 is formed in one with the inner sleeve 12 of plug 1, and tubular shell fragment 23 the inners in the cylinder base 21 of socket 2 are provided with a lug 231, this lug 231 is welded on outer sleeve 11 surfaces of plug 1, and the socket 2 and the positive and negative electrode of plug 1 are connected as a single entity separately.

According to above-mentioned structure, because the inner sleeve 12 of the center latch 22 of socket 2 and plug 1 forms for one car system, thus exempted each trouble of connecting in making and subsequent group load of part in addition, so reduced manufacturing cost, improved the market competitiveness.

Guide card 14 is connected with inner sleeve 12 contacts of plug 1 again, the positive pole 31 of power line 3 is connected with guide card 14, make the center latch 22 of socket 2 and the inner sleeve 12 of plug 1 be the positive pole of power supply, the negative pole 32 of power line 3 is connected with the cylinder base 21 of socket 2, makes the outer sleeve 11 of plug 1 and the cylinder base 21 of socket 2 be the negative pole of power supply.

Tubular shell fragment 23 the inners in the cylinder base 21 of above-mentioned socket 2 are provided with lug 231, and this lug 231 directly is welded on outer sleeve 11 surfaces of plug 1, have therefore exempted the trouble and inconvenience that connect by lead, and have reduced manufacturing cost, have improved the market competitiveness.
