Description

Chargeable electric torch

Technical field

The utility model relates to a kind of Chargeable electric torch.

Background technology

There is multiple Chargeable electric torch in the prior art.Usually, direct current jack is arranged in the torch, and a jack is set on stack shell, and the plug with dc charger during charging is inserted on the direct current jack by jack.The rechargeable torch announced of Chinese patent CN 2360715Y for example, in this Chargeable electric torch, direct current jack is installed in the inside of the switch segments of torch, and jack exposes from another through hole on the tube wall of switch segments.During charging, the plug of dc charger is inserted in this jack.For waterproof, be provided with the sealed rubber pipe that has through hole, when charging, the jack on this through-hole alignment direct current jack when needing sealing, makes sealed rubber pipe rotate an angle with respect to switch segments, makes that the through hole on its through hole and the switch segments staggers mutually.But the reliability of the sealing of this method is bad, when using in the open air, inevitably there is a small amount of conduction liquid to enter the jack of direct current jack by sealed rubber pipe, because it is less in the jack of direct current jack as the distance between the contact of both positive and negative polarity, therefore short-circuit risks is bigger, thereby the possibility that short trouble occurs is higher, and uses very inconvenient.

Therefore, be necessary to design a kind of Chargeable electric torch, make the spacing of the charging contact in the torch can not be subjected to the influence of the spacing of the positive and negative electrode in the standard component dc charger plug, thereby can be bigger than this spacing, so in use or in when charging, can reduce the short trouble of rechargeable battery.

The utility model content

Technical problem to be solved in the utility model is: a kind of Chargeable electric torch is provided, make the spacing of the charging contact in the torch can not be subjected to the influence of the spacing of the positive and negative electrode in the standard component dc charger plug, that is to say, distance between the charging contact of Chargeable electric torch can design greatlyyer, the time all can reduce the short-circuit risks of rechargeable battery so in use or in charging.

According to the utility model, a kind of Chargeable electric torch is provided, comprise: the torch body, described torch body comprises first stack shell and second stack shell, first stack shell comprises lamp holder zone and the switch region that accommodates lamp adapter assembly, accommodates rechargeable battery in second stack shell, it is characterized in that, also comprise with the torch body be separated, by the switch region to described rechargeable battery powered cradle, be provided with direct current jack in the cradle.Be provided with in the switch region that vertical distribution, an end along described torch body passes stack shell with stack shell with insulating mutually and two charging contacts exposing, described cradle be provided with two with the corresponding electric current pin of described charging contact.

The utility model separates cradle and torch body, that is, cradle is arranged on outside the torch body, and direct current jack is integrated in the cradle.The advantage that it produced be charging be by the spacing of stretching out on cradle charge arbitrarily be provided with in probe and the switch region, an end and stack shell pass with insulating mutually stack shell and the same spacing that exposes arbitrarily two contacts that charge contact and realize.The charging probe is electrically connected with direct current jack in cradle, and the spacing of charging probe can be preset.Spacing between the charging contact that stretches out from the torch body also can be preset.The spacing of charging probe and corresponding the getting final product of spacing of charging between the contact.Like this, just can design the spacing of charging probe and the spacing between the charging contact bigger.

Described switch region is provided with an insulation bearing in barrel.This insulation bearing one side is used to support the other end that does not expose of charging contact, and opposite side is used for supporting the switch module that is arranged on the switch region.Bearing is the plate object that a side has two projectioies, and stretch out in a side that supports described charging contact these two protrusion accommodation sections, and the position is corresponding with the charging contact.Protrusion is provided with internal thread in the accommodation section, and the other end that does not expose of charging contact is provided with external screw thread.Thereby protruding the accommodation section can screw togather with the other end that does not expose of charging contact.

Also be provided with the switch module that ribbon gymnastics is made button in the switch region, button one side of described switch module is stretched out at the side tube-wall place of the barrel that stretches out with respect to the charging contact, and its button opposite side is supported on the opposite side of described bearing.That is to say that switch module stretches out from relative barrel respectively with the charging contact, and its part of not stretching out is supported on respectively on the both sides that are arranged on the insulation bearing in the barrel.Therefore, the design of torch main body structure is comparatively compact.

Described charging contact is a T shape, and its larger diameter end is a bared end, and its smaller diameter end is bared end not.The charging contact be socketed with a spring assembly respectively, described spring assembly will charge respectively contact be connected as the stack shell of GND and the positive pole of battery.Spring assembly is made of the leaf spring of helical spring and band opening respectively, and helical spring and leaf spring are socketed in the end that do not expose of described charging contact successively.Certainly, also can consider spring assembly is designed to the spring part of one.

Described cradle is a trench structure, and the one end offers the draw-in groove that can tighten the torch body, and the other end offers the cannelure of placing the torch body, and the electric current pin is arranged on the bottom of described draw-in groove.Be symmetrically arranged with the holding section, location in the described draw-in groove, the chucking projection that described location snap portions does not comprise first locating surface and protrudes from first locating surface, first plane of orientation is smooth face, and the stack shell in the described switch region is symmetrically arranged with two second smooth locating surfaces that cooperate with described first plane of orientation.Preferably, the pedestal of cradle is an elastic plastic member.The torch body can apply the elastic compression power of making every effort to overcome the clothes projection to be separated with cradle.

The torch body of the utility model Chargeable electric torch, because with cradle and the torch body is separated and direct current jack is arranged in this cradle, thereby can be in the switch region, be vertically arranged with the charging contact that two spacings can be provided with arbitrarily, but so contact pitch of described spacing overgauge plug positive and negative electrode, though cause the rechargeable battery short circuit so a spot of water or other conduction liquid can make the contact of the positive and negative electrode of standard plug be electrically connected, but can not short circuit connect two charging contacts, so can reduce the short trouble of rechargeable battery.In addition, the torch body according to the utility model Chargeable electric torch also has the comparatively compact advantage of structure.
