Embodiment
Exemplary embodiment of the present invention is described below with reference to accompanying drawings.
Fig. 1 represents the outside drawing of data link module 1 according to an illustrative embodiment of the invention.
With reference to Fig. 1, this data link module 1 can be between equipment transmission of electric signals and light signal, and have cable 3 and be attached to connector 2 on the end of cable 3.Cable 3 is for being combined with the single bundle of eight wires and four optical fiber in it.
Fig. 1 also show the top end that is arranged in each connector 2, treat the electric connector 24 (describing in detail after a while) that is connected with external equipment.
Fig. 2 represents the exploded perspective view of connector shown in Figure 12.
With reference to Fig. 2, connector 2 is by housing main body 26, cover 25 and wait to be contained in housing main body 26 and the substrate 20 that covers in 25 constitutes.
On the end face of base main body 21 and the back side, electric wire is installed.Therefore, the electric connection 231 (referring to Fig. 3) of the LED222 of led section 22 and electric connection part 23 is electrically connected on the electric wire that is installed on the base main body 21.Fig. 2 also shows line 221, and this line is used for the LED that is wired to led section 22 222 that will be installed on the base main body 21.
Be provided with contact 211 on item face and the back side of base main body 21, be used for being connected with electric connector 24, electric connector 24 is positioned at the end face opposing end faces place that is connected with cable 3 with base main body 21.Contact 211 is connected on the electric wire that is installed on the base main body 21.Therefore, electric connector 24 is electrically connected with LED 222 and electric connection 231 by contact 211.Described LED is the example according to " the signal media conversion element " of this exemplary embodiment.Form porose 21a in the base main body 21, be used for when this base main body is housed inside housing main body 26, positioning.
Housing main body 26 has the boss 261 that is arranged on its inner bottom surface.All has thread groove in each boss 261.In assembling during connector 2, at first, will cover 25 then and be placed on base main body 21 and the housing main body 26 by boss 261 being inserted pass the hole 21a of base main body 21 and base main body 21 being assemblied in the housing main body 26.By being screwed into, the screw (not shown) is formed in the hole 25a of cover in 25 and clamp connector 2.In addition, housing main body 26 has at some position formation hole 26b within it, thereby electric connector 24 is plugged between the 26b of these holes.Lock screw 262 is inserted and is passed hole 26b, to guarantee engaging of electric connector 24 and matching connector.
Fig. 3 is illustrated in the connector 2 shown in Fig. 2 and cuts open the cutaway view of getting with the part place that the cable 3 shown in Fig. 1 is connected.
Fig. 3 shows the led section 22 on the end face that is fixed to base main body 21.This led section 22 is made up of LED222 and framework 220.
Fig. 3 also shows the electric connection part 23 on the back side that is fixed to base main body 21.This electric connection part 23 is made up of electric connection 231 and framework 230.
In addition, Fig. 3 shows and comprises optical fiber 31, electric wire 32 and bind round 30 cable 3.Hoop 30 has the patchhole 30b that inserts for the end of the patchhole 30a of the end insertion of optical fiber 31 and supply lines 32.
The framework 220 of led section 22 and the framework 230 of electric connection part 23 have bonding part 22a respectively and 23a binds round 30 to receive, connect thereby when being inserted into hoop 30 among bonding part 22a and the 23a, can between LED222 and optical fiber 31, form light, between electric connection 231 and electric wire 32, form and be electrically connected.
Can handle electrical transmission again although can either handle optical transmission according to the data link module 1 of this exemplary embodiment, the part that module 1 is linked to external equipment only limits to electric connector 24.Therefore, the number of times that module 1 engages drops to half of the conventional module that can carry out optical transmission and electrical transmission, and conventional module connects for light and is electrically connected needs at least twice bonding operation.Therefore, described data link module 1 has reduced the work when chained device.In addition, owing to only be inserted among bonding part 22a and the 23a and easily connector 2 be connected on the cable 3 by bind round 30, so also change cable 3 easily.
In addition, in order to reduce the thickness of substrate 20, four LED222 in led section 22 are configured to be arranged in rows along the side of base main body 21, thereby are connected with electric wire on the end face that is installed in base main body 21.By the same token, eight electric connections 231 of electric connection part 23 are arranged in rows along the side of base main body 21, thereby are connected with electric wire on the back side that is installed in base main body 21.
The cutaway view of the cable 3 shown in Fig. 4 presentation graphs 1.
As shown in Figure 4, in cable 3, be inserted with core 35, thus make four optical fiber 31 in this cable each other side by side.With four groups of electric wires 32 of two one group that metallic sheath 33 covers described four optical fiber 31 and wraps up with aluminium foil 321, this metallic sheath covers with sheath 34 again.
As previously mentioned, in order to reduce the thickness of substrate 20, the LED222 of data link module 1 and electric connection 231 are arranged in rows along the side of base main body 21.Optical fiber 31 in cable 3 each other side by side, thereby corresponding with the LED222 that is arranged in rows on the position, prevent thus owing to error of transmission takes place in optical fiber 31 distortion.
In addition, aluminium foil 321 and the metallic sheath 33 by each two wire of organizing 32 of parcel shielded electromagnetic noise reliably.
Fig. 5 A to Fig. 5 C represents being connected between substrate 20 and the cable 3.
Fig. 5 A is when hoop 30 is received by the bonding part 23a of the bonding part 22a of led section 22 and electric connection part 23 (referring to Fig. 3), from covering the top view that is connected between 25 observed substrates 20 and the cable 3.
In Fig. 5 A, divested near the part the end of cable 3 of sheath 34, to expose cover 33.
In Fig. 5 B, the base main body 21 shown in Fig. 5 A is accommodated in the housing main body 26, and overlaps 33 expose portion and be fixed on the edge 260 of housing main body 26 by securing member 27.
Fig. 5 C is illustrated in the cutaway view that the cable of getting 3 is cutd open in position on cable 3 is fixed to housing main body 26 by securing member 27 the edge 260.
Shown in Fig. 5 C, because the cover 33 of cable 3 is connected on the metal shell main body 26 of connector 2, so the electric current that connector 2 can be by cable 3 provides good ground connection, thereby suppressed the harmful effect that causes owing to electromagnetic noise.
According to above-mentioned exemplary embodiment, be inserted among bonding part 22a and the 23a and connector 2 is connected on the cable 3 by binding round 30.Yet the present invention is not limited to described exemplary embodiment, connector 2 can be directly connected on the cable 3, and need not to get involved hoop 30.Perhaps, cable 3 can overlap covering, perhaps can not be connected on the housing main body 26 by securing member 27.
The foregoing description of exemplary embodiment of the present is provided for the purpose of illustration and description.Be not intended to limit or the present invention is limited to disclosed precise forms.Obviously, many modifications and variations all are conspicuous to one skilled in the art.Selecting and having described described exemplary embodiment is to be suitable for concrete various modifications of using for principle of the present invention and practical application thereof being described best, making others skilled in the art can understand various embodiment of the present invention whereby and reckon with.Scope of the present invention is intended to limit by claims and equivalent thereof.
