Abstract
The utility model discloses an automatic contacting lamp holder, which comprises a lamp cap which is connected with the sleeve of a bulb by inserting together; two contacting pieces inside of the lamp cap are connected with a positive power supply and a negative power supply. The lower part of the contacting piece is arranged with collects on which spring pieces are provided; on end of the spring piece is fixedly contacted with a left contacting piece, and the other end of the spring piece is contacted with the contacting head of the right contacting piece on free state. When one bulb is burnt off, a user just needs to unpin the bulb and the spring piece can make the lamp string keep return circuit; thus this design makes other bulbs implement the effect of normal luminescence.
Description
Technical field
The utility model relates to the holder connecting device in a kind of lamp string, particularly a kind of automatic contact lamp holder.
Background technology
Festival lamp luster is because moulding is varied and light flash is colorful, have the night illumination decorative effect and form the first-selection that increases festive air for people's conduct in red-letter day, but the festival lamp luster that generally uses on the market is linked up all bulb strings by a power line usually now, after a certain bulb is burnt on the lamp string, will cause whole lamp string normally not use, thereby influenced decorative effect greatly, and the connected mode complexity of its bulb on lamp holder, cause replacing with also inconvenience.
Summary of the invention
In order to overcome the deficiencies in the prior art, the automatic contact lamp holder that the utility model provides a kind of lamp string to use.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of automatic contact lamp holder, the lamp holder that comprises grafting bulb sleeve, two contacts that link with positive-negative power respectively about having in the lamp holder, there are collets described contact below, spring leaf is arranged on the collets, spring leaf one end fixedly contacts with left contact, and the other end contacts with contact on the right contact under free state; Described spring leaf tail end is connected in the collets.
The beneficial effects of the utility model are: when the bulb sleeve is inserted lamp holder, the contact that connects positive-negative power contacts with the both positive and negative polarity of bulb sleeve, thereby make the bulb on the bulb sleeve normally luminous, simultaneously, the bulb sleeve is the spring leaf compression of collets tops, makes it to separate with contact on the contact; When the bulb sleeve does not insert lamp holder, reply normal condition at elastic force effect lower spring sheet, contact with contact on the contact, thereby make lamp string maintenance loop, so after a certain bulb is burnt on the lamp string, just can make other bulb reach the effect of normally lighting as long as bulb pulled out.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Structural representation when Fig. 1 is the utility model installation bulb sleeve;
Fig. 2 is the structural representation of the utility model when the bulb sleeve is not installed.
Embodiment
With reference to Fig. 1, Fig. 2, a kind of automatic contact lamp holder, the lamp holder 1 that comprises grafting bulb sleeve 2, two contacts 3,4 that link with positive-negative power respectively about having in the lamp holder 1, there are collets 5 described contact 3,4 belows, collets 5 with about two contacts opened in 3,4 minutes, prevent contact 3,4 contacts and caused short circuit, spring leaf 6 is arranged on the collets 5, and spring leaf 6 one ends fixedly contact with left contact 3, and the other end contacts with contact 7 on the right contact 4 under free state.
When bulb sleeve 2 is inserted lamp holder 1, the contact 3,4 that connects positive-negative power contacts with the both positive and negative polarity of bulb sleeve 2, thereby makes the bulb on the bulb sleeve 2 normally luminous, simultaneously, bulb sleeve 2 is spring leaf 7 compression of collets 5 tops, makes it to separate with contact 7 on the contact 4; When bulb sleeve 2 does not insert lamp holder 1, reply normal conditions at elastic force effect lower spring sheet 7, contact with contact 7 on the contact 4, thereby make lamp string maintenance loop, so after a certain bulb is burnt on the lamp string, just can make other bulb reach the effect of normally lighting as long as bulb pulled out.
The utility model is connected to spring leaf 6 tail ends in the collets 5; thereby guarantee when reaching stationary spring 6 that spring leaf 6 fixedly contacts with left contact 3; also the spring leaf 6 of length less than distance between two contacts 3,4 can be placed between two contacts 3,4 in design; and under free state, contact with contact 7 on two contacts 3,4; but the installation high request of this design; use inconvenient; no matter but use which kind of mode; as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection range of the present utility model.
Claims (2)
