Description

Handfree receiver unit

The utility model relates to a kind of handfree receiver unit of communication electro-acoustic element, particularly a kind of replaceable connecting interface, and it can cooperate different vehicular telephones and change the signal connecting interface of same types.

Along with the requirement of people to communication service, the popularity rate and the Occupation coefficient of vehicular telephone increase rapidly, because of vehicular telephone easy-to-use, in any place and any time, as long as can collect mail and can communicate by letter.

Yet, use vehicular telephone to still have inconvenience, even under some environmental aspect, also have danger; When just carrying thing, or when driving, can't vacate on the other hand and grip vehicular telephone as both hands, also therefore, existing handfree receiver unit appearance, and the kind of handfree receiver unit is a lot of, as shown in Figure 6, it is a kind of common handfree receiver unit; The convenience that handfree receiver unit provides makes the use of vehicular telephone more become to improving facility really; But also have corresponding problem, because the label type of vehicular telephone is numerous on the market, the vehicular telephone of each producer all has its signal gang socket separately, uses its special-purpose interface signal line 18; Therefore, existing being seen on the market handfree receiver unit only is suitable for specific label, specific model specification mostly, can't be general.

In addition, the interface signal line 18 of whole handfree receiver unit is exposed to the outside, uses also inconvenience, and influences outward appearance.

Main purpose of the present utility model is to provide a kind of handfree receiver unit that is common to various vehicular telephones; Its by a main base frame and in be provided with replaceable connecting interface, cooperating various Connection Block, can replace the Connection Block that is suitable at the signal connection end of different labels, different model, make handfree receiver unit be applicable to the vehicular telephone of various label.

For achieving the above object, the utility model is taked following technical measures:

Handfree receiver unit of the present utility model comprises: a main base frame, a Connection Block, a signaling conversion circuit plate and a Handless motherboard;

The Handless motherboard is located at main base frame inside;

Place, main base frame below is provided with a lid, and lid and main base frame are articulated; The main base frame relative position place at opening cover place is provided with the storage tank of an installing Connection Block:

The upper end of Connection Block is provided with inserted terminal, and the below of Connection Block connects the signaling conversion circuit plate, and the signaling conversion circuit plate is provided with transom, to engage with corresponding transom on the main base frame in-to-in Handless motherboard, to finish the transmission of signal.

Wherein, described lid medial surface be provided with main base frame on the draw-in groove grab of blocking mutually at relative position place.

Wherein, described transom is a Signal connector.

Wherein, described transom is connected with Signal connector by a connection lead.

Wherein, described storage tank both sides are respectively equipped with clamping groove, cooperate the holding limit of described Connection Block both sides, and described Connection Block is installed in the storage tank of described main base frame.

Wherein, described Connection Block is connected with signal connecting line with the signaling conversion circuit plate.

Reaching embodiment in conjunction with the accompanying drawings is described in detail as follows architectural feature of the present utility model:

Description of drawings is as follows:

Fig. 1: three-dimensional combination figure of the present utility model;

Fig. 2: three-dimensional exploded view of the present utility model;

Fig. 3: local structure cut-away view of the present utility model;

Fig. 4: running condition scheme drawing of the present utility model;

Fig. 5: another embodiment local structure scheme drawing of the present utility model;

Fig. 6: the schematic perspective view of existing handfree receiver unit.

As shown in Figure 1, 2, 3, the handfree receiver unit of the replaceable connecting interface of the utility model comprises a main base frame 1 and Connection Block 2 at least;

Main base frame 1 positive place is provided with a grip slipper 11; The vehicular telephone of the applicable multiple label type of clamp structure that grip slipper 11 is adjustable is put, and can firmly be folded in it;

The place, below of main base frame 1 is provided with a lid 12, and lid 12 can be articulated with main base frame 1 and combine, and can open shape and be; On lid 12 medial surfaces, can establish grab 121,, may be stuck on the draw-in groove of the relative position place of main base frame 1 establishing 16, play fixation with when lid 12 is closure state.

The main base frame 1 relative position place at opening cover 12 places is provided with one and is cross storage tank 14, and storage tank 14 both sides are respectively equipped with clamping groove 141.

The upper end of Connection Block 2 is provided with inserted terminal 21, and inserted terminal 21 is complied with the Connection Block 2 of the vehicular telephone type that is suitable for different labels, and establishes the inserted terminal 21 to be suitable for; Connection Block 2 both sides are provided with holding limit 23, utilize holding limit 23 sliding putting in the clamping groove 141 of the storage tank 14 that snaps in main base frame 1 relative position during installing; Connection Block 2 is positioned in the storage tank 14, and the inserted terminal 21 of its upper end just can cooperate the grip slipper 11 of main base frame, makes to place the signal connection end of the vehicular telephone lower end in it to combine with the inserted terminal 21 of Connection Block 2.
