Abstract

The utility model relates to a bulb power input line, in particular to an improved structure of the connecting terminal of the bulb power input line used for the electrical connection of a bicycle lamp and a power source. The bulb power input line comprises an electric line and a male connecting terminal arranged at the end part of the electric line, wherein, the splicing part of the male connecting terminal comprises a palm part and a finger part, the finger part is narrower than the palm part, and the finger part is formed at the front end of the palm part. When being used, if the bulb power input line is spliced with a narrower female connecting terminal, the utility model is directly used to be spliced, namely the finger part is used to be matched with the female connecting terminal; if the bulb power input line is spliced with a wider female connecting terminal, the finger part of the utility model is broken off firstly, and then the wider palm part is used to be spliced. The utility model has simple and reasonable structure, the purpose of the exchanging is skillfully achieved under the precondition of the connecting quality is not affected, and the operation is very convenient.

Description

The bulb power incoming line

(1) technical field

The utility model relates to a kind of bulb power incoming line, the architecture advances of the binding post of the bulb power incoming line that is electrically connected with power supply in particular for car light.

(2) background technology

Existing car light bulb power incoming line has the public access line terminals of plurality of specifications as the power input line on the HID xenon lamp, also is furnished with female binding post of corresponding specification on power supply or the ballast.Wherein, model commonly used has 9006 and two kinds of H7 (as shown in Figure 1, 2), these two kinds of male and female binding posts, 9006 narrower, and the broad of H7 so do not match mutually, is pegged graft after can't exchanging, wiring inconvenience when often causing lamp installation.

(3) summary of the invention

The purpose of this utility model is to provide a kind of bulb power incoming line that can peg graft with female binding post of two kinds of specifications.

For achieving the above object, the utility model is by the following technical solutions:

A kind of bulb power incoming line comprises electric wire and is fixed in the public access line terminals of wire end, and the grafting part of described public access line terminals is made of a metacarpus and a finger, and the finger is narrower than metacarpus, and the finger forms in the metacarpus front end.

During use,, directly insert connection, promptly use the finger to cooperate with female binding post with the utility model as pegging graft with narrower female binding post; As pegging graft with female binding post of broad, can earlier finger of the present utility model be fractureed, peg graft with the metacarpus of broad then.

Technique scheme can also be further improved by following technical measures.

The ratio of described finger width and metacarpus width is greater than 0.2 and less than 0.8.

Described finger width is greater than 0.3 and less than 0.7 with the ratio preferred range of metacarpus width.

The ratio of described finger width and metacarpus width is preferably greater than 0.4 and less than 0.6.

Described finger and metacarpus joint are step-like.Described finger and metacarpus joint have easy to break mouthful.This two structure can be convenient to the disconnection of finger and metacarpus.

Be arranged with the leakproof gum cover on the described electric wire, leakproof gum cover front end has opening, its rear end and the electric wire interference fit that can cooperate with female binding post.During use, earlier the male and female binding post is inserted, again the leakproof gum cover is enclosed within outside the binding post, prevent the joint loose contact of making moist.

Described finger front end is formed with the awns portion narrower than the finger.This three stage structure goes for three kinds of female binding posts.

The utility model is simple and reasonable, under the prerequisite that does not influence bond quality, has reached the purpose of exchanging cleverly, uses very convenient.

(4) description of drawings

Fig. 1 is that existing model is the schematic perspective view of 9006 public access line terminals;

Fig. 2 is that existing model is the schematic perspective view of the public access line terminals of H7;

Fig. 3 is a schematic perspective view of the present utility model;

Fig. 4 is a floor map of the present utility model;

Fig. 5 is the right view of Fig. 4;

Fig. 6 is the vertical view of Fig. 4.

(5) embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Shown in Fig. 3-6: a kind of bulb power incoming line, comprise electric wire 1 and be fixed in the public access line terminals 2 of wire end, the grafting part of described public access line terminals 2 is made of a metacarpus 21 and a finger 22, finger 22 and metacarpus 21 are one, finger 22 is narrower than metacarpus 21, and finger 22 forms in metacarpus 21 front ends.Finger 22 width are 3 millimeters, and metacarpus 21 width are 6 millimeters.Described finger 22 is step-like with metacarpus 21 joints.Be arranged with leakproof gum cover 3 on the described electric wire 1, leakproof gum cover 3 front ends have opening, its rear end and the electric wire interference fit that can cooperate with female binding post.

In conjunction with Fig. 1,2 as can be seen, the size of finger 22 and shape and model are that shape, the size of 9006 public access line terminals is close; The size of metacarpus 21 and shape and model are that shape, the size of the public access line terminals of H7 is close.
