Abstract

The utility model discloses a charging socket with contacts on two sides. The charging socket includes a socket shell. The charging socket also includes: a first metal contact and a second metal contact which are arranged in a first row and are extended backwardly along the socket shell to form pins which are used for welding a circuit board, and a third metal contact and a fourth metal contact which are arranged in a second row and are extended backwardly along the socket shell to form pins which are used for welding the circuit board. The first metal contact and the third metal contact are symmetrical with respect to a center of the socket. The second metal contact and the fourth metal contact are symmetrical with respect to a center of the socket. A contact reliability of the charging socket can be improved and a current-carrying capacity can be increased since the two rows of the metal contacts. The two rows of the metal contacts are respectively symmetrical with respect to a center of the socket so that a plug is allowed to be inserted not only positively but also negatively. Not only is performances of the socket improved but also the socket is convenient for users to use.

Description

There is the charging socket of contact a kind of both sides

Technical field

The utility model relates to the charging inlet of stand-by power supply of mancarried electronic aid.

Background technology

Along with development in science and technology, electronic product development, has greatly facilitated people's life.As portable set, its maximum feature is exactly light, and therefore, built-in battery capacity is limited.Need to charge quickly and easily.

Existing charging socket, the inadequate volume having is little and thin; Although the volume having is little, loaded current is less; Cannot meet the demand of large current charge.In addition, interface generally has directivity, if anti-inserted, easily damages socket.

Summary of the invention

for the problems referred to above, the utility model aims to provide a kind of both sides the charging socket of contact: both volume was little and thin; Loaded current is larger simultaneously, meets the demand of large current charge.In addition, insertion can not have directivity, is not easy to damage socket.

for realizing this technical purpose, scheme of the present utility model is:there is a charging socket for contact both sides, comprise jack housing, also comprise metal the first contact and metal second contact of the first row, and metal the first contact and metal the second contact extend back along jack housing respectively, form the pin of soldered circuit board; The metal of the second row the 3rd contact and metal the 4th contact, metal the 3rd contact and metal the 4th contact extend back along jack housing respectively, form the pin of soldered circuit board; Metal the first contact and metal the 3rd contact are about socket Central Symmetry; Metal the second contact and metal the 4th contact are about socket Central Symmetry .

as preferably, extend along jack housing respectively metal the first contact, metal the second contact, metal the 3rd contact and metal the 4th contact in this device, forms four pins of soldered circuit board.

as preferably, after metal the first contact in this device is connected with metal the 3rd contact, extends back and form the pin of soldered circuit board along socket; After metal the second contact is connected with metal the 4th contact, extends back and form the pin of soldered circuit board along socket; Socket has the pin of two soldered circuit boards.

as preferably,, can there be respectively the hard contact more than two two row metal contacts in this device; Wherein in two row corresponding hard contact respectively about the Central Symmetry of socket .

the beneficial effect of the technical program is: this charging socket had both met the demand of large current charge, can plug more easily again use; It is the charging socket that portable equipment and stand-by power supply are more suitable for.

Embodiment

below in conjunction with the drawings and specific embodiments, the utility model is described in further details.

as shown in Figure 1, of the present utility modelthere is a charging socket for contact both sides, comprise jack housing 1, also comprise metal first contact of the first row 2with metal the second contact 3, metal the first contact 2with metal the second contact 3extend back along jack housing respectively, form the pin of soldered circuit board; Also comprise metal the 3rd contact of the second row 4with metal the 4th contact 5, metal the 3rd contact 4with metal the 4th contact 5extend back along jack housing respectively, form the pin of soldered circuit board; Metal the first contact 2with metal the 3rd contact 4about socket Central Symmetry; Metal the second contact 3with metal the 4th contact 5about socket Central Symmetry .The intersection point of dotted line indicates socket center in front view.

as shown in Figure 2, extend along jack housing respectively metal the first contact 2, metal the second contact 3, metal the 3rd contact 4 and metal the 4th contact 5 in this device, forms four pins of soldered circuit board: pin 6, pin 8, pin 9, pin 7.Metal the first corresponding pin 6 in contact 2, metal the second corresponding pin 8 in contact 3, metal the 3rd corresponding pin 9 in contact 4, metal the 4th corresponding pin 7 in contact 5.Electrical property relation between each contact, is determined by the circuit on welded circuit board.

as shown in Figure 3,metal the first contact in this device 2with metal the 3rd contact 4after being connected, extending back and form the pin of soldered circuit board along socket 11; Metal the second contact 3with metal the 4th contact 5after being connected, extending back and form the pin of soldered circuit board along socket 10; Socket has the pin of two soldered circuit boards .

the above; it is only preferred embodiment of the present utility model; not in order to limit the utility model, any trickle amendment that every foundation technical spirit of the present utility model is done above embodiment, be equal to and replace and improve, within all should being included in the protection range of technical solutions of the utility model.
