Abstract
The utility model discloses an earphone pin improving practicality, and the earphone pin comprises a smartphone, an earphone sleeve, an earphone jack, external equipment, a housing projection part, a pin extension part, and an earphone pin. The housing projection part is connected with the pin extension part, and the pin extension part is connected with the earphone pin. The external equipment is provided with a part for installing the earphone pin. The earphone pin is designed in an outwards-bulged structure, thereby forming the housing projection part, enabling the whole body of the pin to be extended outwards. A type of pin, which is provided with an extension part at the rear part of an electrode, is selected for the earphone pin, thereby enabling the electrode of the earphone pin to be extended outwards. After the external equipment is plugged into the earphone jack, the housing projection part of the external equipment and the extension part at the rear part of the pin electrode are stacked, thereby enabling the distance between an equipment housing and a mobile phone housing to be increased obviously. The equipment housing cannot contact with a mobile phone protection sleeve, and the earphone is easy to plug in place.
Description
Technical field
The utility model relates to a kind of newly-designed earphone contact pin, particularly improves the earphone contact pin of practicality.
Background technology
A lot of consumers, in order to protect mobile phone often a containment vessel on cell-phone cover, have preformed hole in earphone jack part, and earphone jack has just become " deeply " relatively like this.Like this, for the earphone of audio frequency output, contact pin rear section is elongated; can be inserted into smoothly position, but partly with the equipment of earphone contact pin, the device housings of contact pin rear section is very large; after earphone contact pin inserts, shell side face easily touches mobile phone protecting case and causes slotting not in place.
Summary of the invention
The technical problem that the utility model solves is: for the problem of above-mentioned existence, realized with the large equipment of earphone contact pin and can insert smoothly in the mobile phone with containment vessel, improved the practicality of earphone contact pin.
The technical solution adopted for the present invention to solve the technical problems is: the position of mounting ear machine transplanting of rice pin above external equipment, be designed to outwards outstanding structure, and contact pin entirety is extended outward; Contact pin selects electrode rear portion to have the contact pin model of prolongation, and contact pin electrode can be extended outward.
Equipment inserts after handset earphone jack, and the prolongation at device housings ledge and contact pin electrode rear portion is cumulative, and device housings and phone housing distance are obviously increased, and device housings just can not touch mobile phone protective cover, and earphone contact pin is easily inserted into position.
To sum up, due to the technique scheme adopting, the invention has the beneficial effects as follows:
Increased the distance of device housings and phone housing, made device housings can not touch mobile phone protective cover, earphone contact pin is easily inserted into position.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structure chart of the present utility model.
Fig. 2 is connection layout of the present utility model.
In figure, 1. smart mobile phone, 2. cell-phone cover, 3. earphone jack, 4. external equipment, 5. shell ledge, 6. contact pin prolongation, 7. earphone contact pin.
Embodiment
In Fig. 1, cell-phone cover 2 is enclosed within on smart mobile phone 1, and has preformed hole to insert smart mobile phone 1 for earphone contact pin 7 in the position of earphone jack 3; In external equipment 4 side casings, have shell ledge 5, shell ledge 5 is connected with earphone contact pin prolongation 6, and earphone contact pin prolongation 6 is connected with earphone contact pin 7.
In Fig. 2; the earphone contact pin 7 of external equipment 4 is inserted in the earphone jack 3 of smart mobile phone 1; because the length of device housings ledge 5 and contact pin prolongation 6 is cumulative mutually; earphone contact pin 7 is inserted into behind position; external equipment 4 and phone housing distance obviously increase; equipment 4 just can not touch mobile phone protective cover 2, and earphone contact pin 7 is easy to be inserted into position.
