Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 and 2, the utility model discloses an optical fiber interface for communication engineering, including setting up the jack 3 on the commuting case, the drill way department of jack 3 is by being equipped with first baffle 1 and second baffle 2 to inside respectively outside, first baffle 1 and second baffle 2 are the structure of running from opposite directions that comprises two door plants, wherein, second baffle 2 is opened to jack 3 is interior, and be equipped with torsional spring 21 in the articulated department of second baffle 2 and 3 lateral walls of jack, under natural state, torsional spring 21 makes two door plants of second baffle 2 be in the closed condition, first baffle 1 is outwards opened, and be equipped with the line hole 11 the same with optic fibre 41 external diameter at the concatenation center of two door plants.
The split door structure refers to a common side-hung door structure which is opened from the middle to two sides in life, one side of the two door panels, which is close to each other, is a free end, the other side of the two door panels, which is away from each other, is a fixed end, and the door panels are hinged with the side wall of the jack 3 through the fixed ends. Since the first shutter 1 is formed by two door panels, the line hole 11 is also formed by a semicircular groove formed in the two door panels. In order to facilitate manufacturing and mounting of the baffle plate structure, the cross section of the insertion hole 3, the first baffle plate 1 and the second baffle plate 2 are all set to be rectangular.
The specific working state of the optical fiber structure is as follows: when the jack 3 is in an idle state, the two door panels of the second baffle 2 are in a closed state under the action of the torsion spring 21, so that dust is prevented from entering the jack 3, and the first baffle 1 can be in a closed or opened state; when optical fiber head 4 is inserted to needs, need earlier outwards open first baffle 1, this process can penetrate line hole 11 with the finger or with the help of tiny instrument, then two door plants of first baffle 1 are pulled to both sides, insert optical fiber head 4 at last, optical fiber head 4 can inwards push second baffle 2 inwards open getting into the in-process, treat to peg graft after stable, close first baffle 1 again, line hole 11 just blocks on optic fibre line 41, play the sealing effect, accessible interference fit or buckle structure guarantee with jack 3's inseparable joint when first baffle 1 is in the closed condition.
For the first barrier 1 and the second barrier 2, a single-door structure may be employed in addition to the double-door structure. The single-door opening structure has the advantages that the rotating radius of the single-door opening structure is larger, the double-door opening structure is not practical, but the single-door opening structure can be adopted under certain specific conditions, such as the situation that the jack 3 is deeper, and the jack 3 and the optical fiber head 4 are of flat structures. To seal the first baffle 1 with a single-door type, the original wire hole 11 must be replaced by a wire slot 14, as shown in fig. 3, the opening of the wire slot 14 is located on one side of the first baffle 1 away from the hinged end, and the wire slot 14 extends inwards to the center of the first baffle 1, so that after the optical fiber head 4 is inserted, the first baffle 1 can be smoothly closed, and the optical fiber 41 enters the bottom of the wire slot 14 along the opening of the wire slot 14. The further improvement is that a rubber pad 15 can be arranged in the wire slot 14, and the rubber pad 15 is divided into two pieces which are spliced left and right, so that the optical fiber 41 is not influenced to enter the wire slot 14, and the sealing effect on the wire slot 14 can be realized.
When specific structural design, in order to facilitate the installation of first baffle 1 and second baffle 2 the both sides of 3 inner walls of jack are equipped with first fixed block 31 and second fixed block 32 from outside to inside respectively, the stiff end of first baffle 1 and second baffle 2 is articulated with first fixed block 31 and second fixed block 32 respectively. The middle part of the torsion spring 21 is hinged below the second fixing block 32, two ends of the torsion spring 21 respectively abut against the inner wall of the jack 4 and the lower surface of the second baffle 2, and the lower surface of the second baffle 2 refers to the surface facing the bottom of the jack 3 when the second baffle 2 is in a closed state.
With the first shutter 1, there is still the possibility of opening after the insertion of the fiber head 4 because the connection is not sufficiently secure, thus affecting the dust-blocking effect. Therefore, the further improvement is that a projection 12 is arranged on one side of the fixed end of the two door panels of the first baffle plate 1 facing the inside of the jack 3, the axis of the projection 12 is preferably perpendicular to the axis of the first baffle plate 1, the side facing the inside of the inserting hole 3 refers to the side of the first baffle 1 facing the bottom of the inserting hole 3 when the first baffle 1 is in the closed state, the rotating shaft of the first baffle 1 is positioned at the joint of the convex block 13 and the first baffle 1, the two sides of the tail part of the optical fiber head 4 matched with the jack 3 are respectively provided with a limiting block 42, the lug 12 and the limiting blocks 42 are arranged to function, when the optical fiber head 4 is inserted, after most of the optical fiber head 4 enters, the limiting block 42 can contact with the bump 12, and the first baffle 1 is driven to rotate inwards along with the continuous entering of the optical fiber head 4 until the optical fiber head 4 is completely inserted, and the first baffle 1 is just in a closed state. At this time, the limiting block 42 abuts against the protruding block, so that the first baffle plate 1 can be limited and cannot rotate outwards, and the stability of closing the first baffle plate 1 is ensured. When the optical fiber head 4 is pulled out, the first baffle 1 can be opened along the same trend.
Further, when the optical fiber head 4 is in an idle state, the second baffle 2 can already play a good sealing role, and in order to facilitate subsequent insertion of the optical fiber head 4, the first baffle 1 is preferably in an open state, so that the upper surface of the first baffle 1 is provided with the clamping groove 13, the side wall of the jack 3 is provided with the rubber block 33, and when the first baffle 1 is in a completely open state, the rubber block 33 can be inserted into the clamping groove 13 to fix the first baffle 1.
The structure form of the optical fiber interface can also be used for other data transmission interfaces, and can also be used on an exchange box for communication engineering or other equipment needing connecting optical fiber lines.
As shown in fig. 4 and 5, the exchange box with the optical fiber interface includes a box body 5 and a box cover 6, and the box body 5 is further provided with other data interfaces 55 and heat dissipation holes 56. Furthermore, a device with a relatively precise structure is generally arranged in the exchange box, and in the process of transportation and use, excessive vibration can possibly damage the device, so that the box body 5 is divided into an outer shell 51 and an inner wall 52, the sponge pad 7 is filled between the outer shell 51 and the inner wall 52, the upper end of the outer shell 51 is folded inwards to wrap the upper edge of the inner wall 52, and the upper edge of the inner wall 52 is clamped in the fixing groove 54 at the upper end of the inner wall 52 through a clamping column 53. The foam-rubber cushion 7 enables the optical fiber exchange box to be effectively damped, and prevents accidents caused by improper transportation and use, even if the box body is damaged, the foam-rubber cushion can also play a certain role in protecting parts of internal devices.
