Detailed Description
The following description of the technical solutions in the embodiments of the present disclosure will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are some embodiments of the present disclosure, but not all embodiments. Based on the embodiments in this disclosure, all other embodiments that a person skilled in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.
Fig. 1 shows an apparatus for connecting a first hybrid cable and a second hybrid cable according to an embodiment of the present invention. As shown in fig. 1, an embodiment of the present invention provides an apparatus 100 for connecting a first hybrid cable 5 and a second hybrid cable 6. The device 100 comprises a female connection unit 1 and a male connection unit 2. The female connection unit 1 is typically mounted on the end of a first hybrid cable 5 and the male connection unit 2 is typically mounted on the end of a second hybrid cable 6. When the female connection unit 1 is docked with the male connection unit 2, the first and second hybrid cables 5 and 6 can transmit optical and electrical signals through the device 100. Wherein the first hybrid cable 5 comprises a busbar comprising an electrical transmission sub-line 51 and an electrical transmission sub-line 52, reference being made to fig. 2. The second hybrid cable 6 includes a bus bar including a power transmission sub-line 61 and a power transmission sub-line 62, which can be referred to fig. 4.
As shown in fig. 2 and 3, the female connection unit 1 includes a socket body 11 having a socket 111a, a first optical fiber connector 12 inserted into the socket body 11 and connected to an optical fiber of the power transmission sub-line 51 of the first hybrid cable 5, and a first electrical connection member 13 provided on a sidewall of the socket 111a of the socket body 11 and connected to a conductive wire (e.g., a copper wire) of the power transmission sub-line 52 of the first hybrid cable 5. Meanwhile, the female connection unit 1 further comprises a locking nut 15 sleeved outside the socket body 11, and a locking rubber sleeve 16 arranged between the socket body 11 and the locking nut 15.
As shown in fig. 4 and 5, the male connection unit 2 includes a plug main body 21, a second optical fiber connector 22 inserted in the plug main body 21 and connected to an optical fiber of the power transmission sub-line 61 of the second hybrid cable 6, and a second electrical connection member 23 provided on an outer circumferential wall of the plug main body 21 and connected to a conductive wire (e.g., copper wire) of the power transmission sub-line 62 of the second hybrid cable 6.
When in use, the plug main body 21 of the male connection unit 2 is inserted into the socket 111a of the socket main body 11 of the female connection unit 1, and the first optical fiber connector 12 and the first electrical connector 13 in the female connection unit 1 can be sequentially in butt joint with the second optical fiber connector 22 and the second electrical connector 23 in the male connection unit 2, so that not only can the optical transmission sub-line 51 of the first hybrid cable 5 and the optical transmission sub-line 61 of the second hybrid cable 6 be ensured to be in butt joint with each other to transmit optical signals, but also the optical transmission sub-line 52 of the first hybrid cable 5 and the optical transmission sub-line 62 of the second hybrid cable 6 can be ensured to be in butt joint with each other to transmit electrical signals. Then, the lock nut 15 is slid and rotated so that the internal thread of the lock nut 15 is engaged with the external thread provided outside the plug main body 21, thereby forcing the lock nut 15 to connect the socket main body 11 and the plug main body 21 together while pressing the locking rubber sleeve 16.
According to the invention, the applicant innovatively adds the locking nut 15 and the anti-loosening rubber sleeve 16 on the basis of the prior art, wherein the additionally added locking nut 15 can connect the socket main body 11 of the female connecting unit 1 with the plug main body 21 of the male connecting unit 2, so that the male connecting unit 2 and the female connecting unit 1 are ensured to have firmer and more reliable connection when being butted with each other, and even if any mixed cable is pulled by using external force, the locking nut 15 is not easy to cause the disconnection of the male connecting unit 2 and the female connecting unit 1, and effective safety guarantee can be provided for mechanical connection and communication connection between the mixed cables. In addition, when the locking nut 15 connects the socket body 11 and the plug body 21 together, the added anti-loosening rubber sleeve 16 not only can prevent the locking nut 15 from loosening, but also can seal the gap between the socket body 11 and the locking nut 15 to a certain extent, thereby reducing the risk of external pollutants entering and damaging the device 100.
In the present embodiment, as shown in fig. 2, 3, and 6, the socket body 11 includes a large diameter portion 111 having a socket 111a and a small diameter portion 112 closer to the first hybrid cable 5 than the large diameter portion 111. The first electrical connector 13 is preferably a spring sheet, and is configured to pass through the large-diameter portion 111, so that an end portion of the first electrical connector 13 exposed outside the small-diameter portion 112 can be easily connected to the power transmission sub-line 52 of the first hybrid cable 5, and an end portion at the socket 111a can be contacted with the second electrical connector 23 of the male connection unit 2 when the male connection unit 2 is docked with the female connection unit 1, and the docking of the two is completed. On the other hand, as shown in fig. 7, a plurality of engaging grooves 151 are provided in the inner peripheral wall of the lock nut 15, which are spaced around the socket body 11 and are separated from the female screw thereof. As shown in fig. 3 and 8, the locking rubber sleeve 16 includes a flat surface 161 that abuts against the junction between the large diameter portion 111 and the small diameter portion 112 of the socket body 11, and a plurality of snap projections 162 that are fitted one by one with the respective snap grooves 151 of the lock nut 15. The matching mode of the clamping groove 151 and the clamping protrusion 162 can improve the anti-loosening effect of the anti-loosening rubber sleeve 16 on the locking nut 15, and can also better seal the gap between the socket main body 11 and the locking nut 15.
In this embodiment, as shown in fig. 2 and 3, the female connection unit 1 may further include a first adapter cover 14. The first switching cover 14 is sleeved outside the optical transmission sub-line 51 of the first hybrid cable 5, and is fastened on the socket main body 11 to prevent the first optical fiber connector 12 from being withdrawn from the socket main body 11. As one example, the first access cover 14 is configured to be inserted and snapped into the socket body 11. In order to reduce the difficulty of assembling the first access cover 14, the first access cover 14 may be formed by splicing the first sub-cover 141 and the second sub-cover 142, and configured such that the first sub-cover 141 and the second sub-cover 142 can be restrained together by the socket body 11 when the first sub-cover 141 and the second sub-cover 142 are inserted into and caught in the socket body 11. Although the first switching cover 14 may be selected to have an integral structure, the first switching cover 14 formed by splicing the first sub-cover 141 and the second sub-cover 142 may be more easily sleeved outside the light transmission sub-line 51 of the first hybrid cable 5 and fastened to the socket body 11.
In this embodiment, as shown in fig. 4 and 5, the male connection unit 2 may further include a second switching cover 24, where the second switching cover 24 is sleeved outside the optical transmission sub-line 61 of the second hybrid cable 6 and fastened on the plug main body 21 to prevent the second optical fiber connector 22 from being withdrawn from the plug main body 21. As one example, the second transit cover 24 is configured to be inserted and snapped into the plug body 21. Similarly, to reduce the difficulty of assembling the second transit cap 24, the second transit cap 24 may also be spliced from the first and second sub-caps 241 and 242, and configured such that the first and second sub-caps 241 and 242 can be restrained together by the plug body 21 when the first and second sub-caps 241 and 242 are inserted and snapped into the plug body 21. Although the second switching cover 24 may be selected as an integral structure, the second switching cover 24 formed by splicing the first sub-cover 241 and the second sub-cover 242 may be more easily sleeved outside the output sub-wire 61 of the second hybrid cable 6 and fastened on the plug main body 21.
In the present embodiment, as shown in fig. 2 and 3, the first optical fiber connector 12 may be selected from any type of optical fiber connector that can be fitted into the socket body 11, but preferably an MT-type optical fiber connector or an LC-type optical fiber connector that is high in cost performance is suggested. Taking the first optical fiber connector as an MT type optical fiber connector as an example, the first optical fiber connector 12 includes a first ferrule 121, a first line tube 122, a first needle seat 123 and a first elastic member 124, where the first ferrule 121 is fixedly sleeved on an end portion of an optical fiber of the light transmission sub-line 51 of the first hybrid cable 5, and the first line tube 122 is sleeved outside the optical fiber of the light transmission sub-line 51 of the first hybrid cable 5, is sleeved in the first ferrule 121, and is in tight contact with an inner wall of the first ferrule 121. The first hub 123 includes a first guide pin passing through the first ferrule 121 and a hub body abutting against the first wire arrangement tube 122. The first elastic member 124 is sleeved outside the optical fiber of the optical transmission sub-line 51 of the first hybrid cable 5, and one end abuts against the first needle seat 123 and the other end abuts against the inner wall of the first adapter cover 14. The first elastic member 124 may be a compression spring or a rubber sleeve, etc., which can avoid the first ferrule 121 from being damaged due to strong collision when being abutted against the second optical fiber connector 22, particularly the second ferrule 221 (described in detail below), and can continuously maintain good abutment between the first ferrule 121 and the second ferrule 221.
Similarly, as shown in fig. 4 and 5, the second fiber optic connector 22 may be selected from any type of fiber optic connector that can be received within the socket body 11, but preferably is a cost effective MT-type fiber optic connector or LC-type fiber optic connector. Taking the second optical fiber connector as an MT type optical fiber connector as an example, the second optical fiber connector 22 comprises a second ferrule 221, a second line tube 222, a second needle seat 223 and a second elastic member 224, wherein the second ferrule 221 is fixedly sleeved at the end part of the optical fiber of the light transmission sub-line 61 of the second hybrid cable 6, and the second line tube 222 is sleeved outside the optical fiber of the light transmission sub-line 61 of the second hybrid cable 6, is sleeved in the second ferrule 221 and is in tight contact with the inner wall of the second ferrule 221. The second hub 223 includes a second guide pin passing through the second ferrule 221 and a hub body abutting against the second wire discharge tube 222. The second elastic member 224 is sleeved outside the optical fiber of the optical transmission sub-line 61 of the second hybrid cable 6, and one end abuts against the second needle seat 223 and the other end abuts against the inner wall of the second switching cover 24. The second elastic member 224 may be a compression spring or a rubber sleeve, etc., which can avoid the second ferrule 221 from being damaged due to strong collision when being abutted against the first ferrule 121 (described in detail below), and can continuously maintain the first ferrule 121 and the second ferrule 221 to be well abutted.
In the present embodiment, as shown in fig. 2 and 3, the female connection unit 1 may further include a first bus bar cover 18a. One end of the first bus bar cover 18a is fixedly sleeved on the first adapter cover 14, and the other end is fixedly sleeved on the bus bar of the first hybrid cable 5. That is, the first bus bar cover 18a can fix and hold the bus bar of the first hybrid cable 5 on the first transfer cover 14, preventing the first hybrid cable 5 from being separated from the female connection unit 1. In terms of the molding method, the first busbar jacket 18a may be manufactured by injection molding, additive manufacturing, or the like, but in the present embodiment, the first busbar jacket 18a is preferably obtained by injection molding, and the first busbar jacket 18a is an injection molded article obtained by injection molding on the first splice cover 14 and the first hybrid cable 5. The first bus bar cover 18a obtained in this way can be directly fixed to the bus bars of the first splice cover 14 and the first hybrid cable 5 without performing secondary treatment such as bonding or welding.
Meanwhile, in order to reduce the risk of the bus bar of the first hybrid cable 5 breaking at the junction with the first bus bar cover 18a due to frequent bending, the female connection unit 1 may further include a first tail cone cover 17, wherein the first tail cone cover 17 is sleeved outside the first bus bar cover 18a, and one end of the first tail cone cover 17 is fixedly sleeved on the first adapter cover 14 and the other end is sleeved on the bus bar of the first hybrid cable 5. The fixing manner between the first tail cone sleeve 17 and the first adapter cover 14 can be screw connection or clamping connection, etc., and preferably plug-in clamping connection is suggested. In addition, since the first tail cone sleeve 17 has a certain taper, the angle and fatigue of bending of the bus bar of the first hybrid cable 5 at the joint of the bus bar and the first bus bar sleeve 18a can be reduced due to the existence of the taper, and further the risk of fracture of the bus bar of the first hybrid cable 5 at the joint of the bus bar and the first bus bar sleeve 18a due to frequent bending can be effectively reduced.
