Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The embodiment of the invention provides a radio frequency coaxial connector.
As shown in fig. 1 and 2, in one embodiment, the rf coaxial connector includes: the first connector comprises a first shell 101, and the second connector comprises a second shell 102 and a sleeve 103 sleeved on the second shell 102.
In this embodiment, a jack 104 is provided at one end of the first housing 101, the other end is connected to the first cable, and the first end of the second housing 102 is matched with the jack 104, and the second end is connected to the second cable, and when in use, the first end of the second housing 102 is inserted into the jack 104, so that the first cable and the second cable are conducted.
Specifically, a conducting portion 105 is disposed in the jack 104 of the first housing 101, the conducting portion 105 is electrically connected to the first cable, a contact portion 106 is disposed at a first end of the second housing 102, the contact portion 106 is electrically connected to the second cable, the contact portion 106 is matched with the conducting portion 105, and when the first end of the second housing 102 is inserted into the jack 104, the conducting portion 105 contacts with the contact portion 106, so that the first cable and the second cable are conducted.
It should be understood that, in this embodiment, the connection manner between the conducting portion 105 and the first cable and the connection manner between the contact portion 106 and the second cable may refer to the existing connector, which are not further defined and described herein.
The connection between the first housing 101 and the second housing 102 in this embodiment is achieved by the claw 107 and the clamping groove 108. Specifically, the inner wall of the jack 104 of the first housing 101 is provided with a clamping groove 108, the outer side of the second housing 102 is provided with a claw 107 matched with the clamping groove 108, when the first end of the second housing 102 is inserted into the jack 104, the claw 107 can be clamped into the clamping groove 108, and at this time, the second housing 102 cannot be pulled out from the jack 104 due to the limiting function of the claw 107, so that the relative movement of the first housing 101 and the second housing 102 is limited.
In this embodiment, at least one claw 107 is provided, and in a preferred embodiment, the number of claws 107 is plural, and plural claws 107 are disposed around the second object with a certain interval therebetween, so that the accuracy and firmness of connection can be further improved.
In this way, by the cooperation of the claw 107 and the clamping groove 108, the relative positions of the first housing 101 and the second housing 102 are actually determined, so that the contact portion 106 and the conducting portion 105 can be fully contacted, and the situation that the communication condition is affected due to the fact that the contact is not in place, such as virtual connection, is avoided.
Further, the sleeve 103 in this embodiment is slidably sleeved on the outer side of the second housing 102, and can slide on the second housing 102. The sleeve 103 serves to increase the strength of the connection between the first connector and the second connector and to unlock the pawl 107.
The socket 103 is in driving connection with the pawl 107, and when the socket 103 slides in the direction of the second end of the second housing 102, the pawl 107 moves in the direction approaching the axis of the second housing 102, so that the pawl 107 can be unlocked from the engagement groove 108.
As shown in fig. 4, the driving connection may be achieved by means of inclined surfaces, for example, in a specific embodiment, inclined surfaces which are in contact with each other are provided on the rotatable jaw 107 of the sleeve 103, so that when the sleeve 103 slides in the direction of the second end of the second housing 102, i.e. to the right as shown in fig. 4, the jaw 107 is pushed to move in the axial direction close to the second housing 102, i.e. to move downwards as shown in fig. 4, so that the jaw 107 is disengaged from the engagement groove 108.
It is obvious that the particular form of the driving connection is not limited thereto, but can be realized, for example, by providing rollers on the sleeve 103 and inclined surfaces on the jaws 107 abutting the rollers, which are not further limited herein.
Because the connection strength of the claw 107 and the clamping groove 108 is lower, in this embodiment, a first connection portion is further provided on the first housing 101, a second connection portion is provided on the sleeve 103, and when the first end of the second housing 102 is inserted into the insertion hole 104, the sleeve 103 and the first housing 101 can be fixed by matching the first connection portion and the second connection portion, so that the connection strength between the first connection head and the second connection head is improved.
In a specific embodiment, the first connecting portion is an external thread, the second connecting portion is an internal thread matched with the first connecting portion, and in use, the sleeve 103 and the first connecting portion can be connected by matching the external thread with the internal thread.
It should be understood that since the claws 107 and the clamping grooves 108 are provided, when the claws 107 are clamped into the clamping grooves 108, the relative positions of the first and second connectors are fixed, so that the connection effect can be ensured, and the sleeve 103 is connected with the first housing 101 mainly in terms of improving the connection strength, so that when the sleeve 103 is connected, even if it is not connected to the limit position, the sleeve 103 only has a certain influence on the connection strength, and does not have an influence on the communication effect.
In yet another embodiment, as shown in fig. 3, the first connection portion is an outer locking groove 109 and the second connection portion is a locking pin 110 that mates with the first connection portion. Thus, when in use, the sleeve 103 and the first connector can be fixed by only rotating a small angle, and the operation is more convenient.
In this way, the rf coaxial connector of the present invention is matched with the clamping groove 108 through the claw 107, so that the contact portion 106 and the conducting portion 105 can be ensured to be fully contacted, the communication effect is ensured, and the installation is convenient, and meanwhile, the connection strength is improved by connecting the sleeve 103 with the first connection head.
In order to further improve the communication effect, in this embodiment, the contact portion 106 includes an elastic contact piece, and the elastic contact piece abuts against the conducting portion 105 and is elastically deformed when the first end of the second housing 102 is inserted into the insertion hole 104.
In this way, when the first end of the second housing 102 is inserted into the insertion hole 104, the conductive portion 105 abuts against the elastic contact piece and deforms the elastic contact piece, so that the conductive portion 105 of the elastic contact piece can be ensured to be sufficiently contacted, and the possibility of occurrence of false connection can be reduced.
In yet another embodiment, the rf coaxial connector further includes a limit clamp spring 115, where the limit clamp spring 115 is configured to limit the axial movement of the sleeve 103 along the second connector, and the sleeve 103 includes a clamping portion corresponding to the limit clamp spring 115, where the clamping portion abuts against the limit clamp spring 115 when the first connector is locked with the second connector and the sleeve 103 is fixed with the first housing 101.
Specifically, as shown in fig. 3, when the sleeve 103 moves to the left to the limit position, the limit clamp spring 115 just abuts against the clamping portion of the sleeve 103, so that the sleeve 103 cannot move further to the left, and the connection effect is improved.
In yet another embodiment, the rf coaxial connector further includes a resilient return element 111, the resilient return element 111 being coupled to the second housing 102 and the sleeve 103 such that the resilient return element 111 is compressed when the sleeve 103 is slid toward the second end of the second housing 102.
In this embodiment, the elastic restoring element 111 may be a spring or a spring plate, which is exemplified in this embodiment. As shown in fig. 3, when the sleeve 103 slides to the right, it will contact with the elastic restoring element 111 and compress the elastic restoring element 111, at this time, if the sleeve 103 is released, the sleeve 103 will slide to the left under the driving of the elastic restoring element 111, so that the claw 107 can be prevented from being in an inwardly contracted state, and the convenience of use is improved.
Further, in one embodiment, the jack 104 is provided with a positioning hole (not identified), and the first end of the second housing 102 includes a positioning post (not identified) matching the positioning hole. The connection position of the first connector and the second connector can be ensured to be more accurate.
Optionally, the positioning hole is located on the axis of the first connector, and the positioning column is located on the axis of the second connector. In a preferred embodiment, the first connector and the second connector are both cylindrical, so that the connection angle of the first connector and the second connector is not limited any more, and the first connector and the second connector can be connected at any angle, thereby improving the convenience of connection.
Further, the rf coaxial connector further includes a waterproof sealing sleeve 112, and two ends of the waterproof sealing sleeve 112 are respectively connected with the second housing 102 and the sleeve 103 in a sealing manner. The degree of sealing between the sleeve 103 and the second housing 102 can be improved.
Optionally, the rf coaxial connector further includes a first sealing ring 113, where the first sealing ring 113 is disposed in the jack 104, and when the first end of the second housing 102 is inserted into the jack 104, the first sealing ring 113 abuts against the second housing 102. Further, the rf coaxial connector further includes a second sealing ring 114, where the second sealing ring 114 is disposed on the outer side of the first housing 101, and when the sleeve 103 is fixed to the first housing 101, the sleeve 103 abuts against the second sealing ring 114. In this way, the sealing effect between the first connector and the second connector can be further improved.
The foregoing is merely illustrative embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think about variations or substitutions within the technical scope of the present invention, and the invention should be covered. Therefore, the protection scope of the invention is subject to the protection scope of the claims.
