Description

Terminal adapter

Technical field

The present invention relates to be used for annex is connected to the terminal adapter of terminal.

Background technology

The purpose of terminal adapter is as connector, pass through terminal adapter, annex such as headphone, controller, microphone-headphone set component, helmet equipment, portable computer etc. can be connected to terminal, especially Nokia or EADS produce in commercially available THR880 and THR880i Tetra terminal, and be connected to similarly or other terminal equipment, GPS position indicator, mobile radio station etc.In order to be coupled, terminal has attachment unit interface, and terminal adapter electrically connects this attachment unit interface.Desired signal conducts to annex by terminal adapter, and these signals can be, for example audio frequency and/or data-signal.As the specific embodiment of this terminal adapter, THR880 or THR880i adapter are the data transmission sets that is intended to be used to rescue/put out a fire official's use of professional and police service, by it, can send and receive information at the official of a target job.

Because terminal adapter is intended to be used for exigent professional purpose, thus it must be very reliable, have good usability and mechanical robustness and a durability.Terminal generally is placed in user's pocket with the terminal adapter that is connected to terminal, and environment wherein is almost identical with external environment condition: temperature, humidity and mechanical stress change greatly.Terminal needs electric power to come work, by powering as the battery of a terminal part.If battery electric quantity step-down, empty battery will be replaced by new charged battery.

Summary of the invention

The characteristic of terminal adapter of the present invention is to comprise:

---charging socket, charging plug can be connected to this charging socket so that be terminal charge when terminal adapter is connected to terminal, and charging socket comprises the shield plug that is used for protecting with waterproof type charging socket when charging plug is not connected to charging socket.

---accessory cable, be connected to a side of terminal adapter by connector, make that when connector is extracted the angle that the direction of accessory cable departs from from the closure (X) of terminal adapter mostly is α≤45 ° most.

For the present invention, water proofing property is meant the water proofing property according to the classification IP 55 of standard SFS-EN 60529.In the present invention, the closure of terminal adapter is meant such direction, the direction of motion when terminal adapter being mechanically connected to terminal and electrically contacting to form between terminal adapter and terminal.When terminal was THR880 or THR880i, in fact this was almost with identical towards the longitudinal direction of the terminal of antenna from pedestal.For the present invention, directions X corresponding to terminal vertically, the Y direction is corresponding to laterally, and the Z direction is corresponding to the degree of depth, i.e. thickness direction, X, Y and Z are about orthogonal.

Terminal adapter has charging socket, and when terminal adapter was connected to terminal, charging plug can be connected to this charging socket so that terminal is charged.By this way, even long-time continuous is used, terminal also can remain on the state of electric weight abundance easily, because can be charged to end cell by automobile or AC/DC charger when needed.

About charging socket, provide a kind of and be used for when charging plug is not couple to charging socket, protecting charging socket so that the shield plug of its waterproof.This shield plug can be made by elastomer, and the grasping surface (grip surface) that can have the edge (lip) that is used to guarantee water proofing property and be used to catch this shield plug.Shield plug is fastened to the shell of terminal adapter, makes that it can not lost when charging socket does not expose.

Terminal adapter also comprises accessory cable, and it is connected to a side of connector by accessory cable, makes that the direction of free accessory cable departs from 45 ° from the closure of terminal adapter at most when when connector is extracted.The direction of accessory cable is relevant, because especially when the user of terminal is using headphone, terminal often is arranged in user's pocket, makes the user might with the hands do a little things of removing this terminal of use.When terminal adapter of the present invention is arranged in pocket, taken the space of minimum, make the long life of accomplishing terminal adapter simultaneously, because almost there is not external stress to affact accessory cable.

Accessory cable is connected to terminal adapter by connector; in this case, connector as cable clamp with the joint of mechanically protecting accessory cable and accessory cable, as cable support and as the slit between the shell of liner (gasket) encapsulation fitting cable and terminal adapter with waterproof.When specific execution mode was THR880 or THR880i terminal, from the front, accessory cable preferably was connected to the right side of terminal adapter, because the part of the user interface of terminal is positioned at the left side of terminal.In the case, accessory cable does not hinder the use of button on the user interface, but is helping its use in some cases, for example, only uses the situation of terminal by coat on the basis of perception.From the position of accessory cable, the user can easily determine the position of required button, such as tangent direction.

Description of drawings

To specifically illustrate terminal adapter of the present invention with reference to appended accompanying drawing, wherein,

Fig. 1 is the front view of terminal adapter, and

Fig. 2 is to the front view of the terminal adapter of observing diagonally from the lower right.

Embodiment

Fig. 1 illustrates terminal adapter 1, the shield plug 21 that it has terminal adapter shell 11, is arranged in the charging socket 2 of pedestal and is used for charging socket.Accessory cable 3 is connected to the shell 11 of terminal adapter by connector 31, connector 31 as cable clamp with the joint of mechanically protecting accessory cable 3 and accessory cable, support and come slit between the shell 11 of encapsulation fitting cable 3 and terminal adapter as liner with waterproof as cable.The shell 11 of terminal adapter, connector 31 and the accessory cable freely 3 of stretching out connector 31 basically form a plane in the XY plane.Accessory cable 3 is connected to a side of terminal adapter 1, and in this side, terminal self has less such as console switchs such as buttons.Especially, when terminal was THR880 or THR880i terminal, accessory cable was connected to the right side of terminal adapter.

When terminal adapter 1 was connected to the shield plug 21 of terminal and charge closing socket, the connecting portion between terminal and the terminal adapter 1 was a waterproof.For this purpose, terminal adapter 1 has elastic insert 15, and when the respective surfaces of contact terminal, it makes the connecting portion waterproof between terminal adapter 1 and the terminal.

Terminal adapter 1 has the fixture 61 that spring is housed, and such as hook, bail, jaw etc., terminal adapter 1 can be locked into terminal by them.Fixture 61 can be opened by button 62, makes terminal adapter can break away from terminal.Fixture 61 also can be operated by screw.

When connector 31 is extracted, the direction of accessory cable 3 is preferably from the X closure of terminal adapter deviation angle α≤20 ° roughly freely.The value of angle [alpha] is smaller have been reduced terminal and has been connected to the external dimensions of the terminal adapter of terminal, but when the angle of connector during near 90 °, the mechanical strength of structure not necessarily is best again.

Fig. 2 illustrates from another angle, and promptly the terminal adapter of observing from lower right corner side makes that charging socket 2, connector 31 and button 62 can be than seeing clearlyer among the previous figure.
