Description
Technical Field
[0001] The utility model relates to a connector, in particular to a radial contact integrated connector. Background Art
[0002] A connector generally refers to an electrical connector, which is a device that connects two active devices and transmits current or signals. The male and female ends can transmit information or current after contact, and are also called connectors.
[0003] Among them, the connector on the filter, in the conventional method, adopts the welding method, that is, the line is inserted into the connector, and then fixed by welding. In this way, it is inconvenient to connect and disassemble. Among them, an attempt has been made to use the commonly used connector on the market, that is, the plug is inserted into the socket to achieve electrical connection. However, for the connector used for the filter, a plug inner conductor and a plug outer conductor need to be set on the plug, and a socket inner conductor and a socket outer conductor are set on the socket. The plug outer conductor and the socket outer conductor need to be electrically connected, and the plug inner conductor and the socket inner conductor need to be electrically connected. In conventional connectors, due to the problem of processing accuracy, it is difficult to ensure that after the plug inner conductor and the socket inner conductor are plugged in, the plug outer conductor and the socket outer conductor can also be smoothly plugged in and tightly matched. In other words, after the plug outer conductor and the socket outer conductor are tightly matched, the plug inner conductor and the socket inner conductor are also difficult to fit tightly. At the same time, the socket and the plug are assembled from multiple parts. Due to the processing errors between the various parts, after assembly, there may be certain deviations in the axial directions of different sockets and the conductors inside the sockets, resulting in a certain gap between the conductors inside a certain group of sockets and the conductors inside the plug after the plug and the socket are plugged in, resulting in insufficient continuity and stability in the transmission of electrical and signal transmission after plugging in. Therefore, how to solve the above technical problems is the direction that technicians in this field need to work hard on. Summary of the invention

[0027] The utility model is further described below in conjunction with the accompanying drawings and embodiments:
[0028] Example 1: See Figures 1 to 3 As shown, a radial contact integrated connector includes a plug 1 and a socket 2 that are plugged into and matched with each other.
[0029] A socket outer conductor 3 is provided on the right side of the socket 2, and a socket inner conductor 4 is provided inside the socket outer conductor 3;
[0030] The left side of the plug 1 is provided with a plug outer conductor 5 which is plugged and matched with the socket outer conductor 3, and the inside of the plug outer conductor 5 is provided with a plug inner conductor 6 which is plugged and matched with the socket inner conductor 4;
[0031] The outer surface of the left end of the plug outer conductor 2 is evenly distributed with a plurality of spring pieces 7 in a ring shape, and the outer surface of the spring pieces 7 is flush with the outer surface of the plug outer conductor 5, and there is a spacing between adjacent spring pieces 7; an outwardly convex arc-shaped convex portion 8 is provided on the outer surface of the left end of each spring piece 7, and the plug outer conductor 5 and the spring piece 7 are inserted into the socket outer conductor 3, and the outer surface of the arc-shaped convex portion 8 is against the inner surface of the socket outer conductor 3. Among them, the spring piece and the arc-shaped convex portion are also conductors, which will be electrically connected to the plug outer conductor.
[0032] In this embodiment, there are multiple plug outer conductors and multiple socket outer conductors. Each plug outer conductor is inserted into a socket outer conductor. Each plug outer conductor has a plug inner conductor, and each socket outer conductor has a socket inner conductor. When the plug and the socket are plugged in, each plug outer conductor faces a socket outer conductor, the plug inner conductor will be inserted into the socket inner conductor, and the spring sheet and the plug outer conductor will be inserted into the socket outer conductor. When plugging in, due to the existence of the arc-shaped convex portion, the socket outer conductor will squeeze the arc-shaped convex portion, that is, the left end of the spring sheet will deform inward. Through the restoring force of the spring sheet itself, the spring sheet and the arc-shaped convex portion clamp the socket outer conductor, thereby realizing the limit of the plug and the socket, and the radial contact is achieved. The arc-shaped convex portion and the socket outer conductor are in radial contact, which can ensure the stability of the electrical connection. Among them, multiple spring pieces and arc-shaped protrusions form an annular petal structure. When the outer conductor of the plug is inserted into the outer conductor of the socket, the left end of the petal structure becomes smaller through the outer conductor of the socket. The spring piece itself has a restoring force, so that the arc-shaped protrusion can always contact the inner wall of the outer conductor of the socket through the restoring force of the spring piece, thereby achieving stable radial contact and ensuring electrical performance.
[0033] See also Figure 1 As shown, a first plug hole 9 is provided at the right end of the socket outer conductor 3, the diameter of the first plug hole 9 matches the outer diameter of the plug outer conductor 5, the plug outer conductor 5 and a plurality of spring pieces 7 are plug-connected to the first plug hole 9, and the outer surface of the arc-shaped protrusion 8 and the outer surface of the plug outer conductor 5 are against the inner surface of the first plug hole 9.
[0034] In this embodiment, since the diameter of the first socket matches the outer diameter of the plug outer conductor, when the plug outer conductor and the spring sheet are inserted into the first socket, the spring sheet will be squeezed inward through the first socket, causing the spring sheet to deform. In this way, through the deformation ability of the spring sheet itself, the arc-shaped protrusion is subjected to an outward restoring force and is always in contact with the first socket, thereby achieving stable radial contact.
[0035] See also Figure 1As shown, the socket inner conductor 4 is coaxially arranged in the first plug hole 9, and a gap is provided between the right end of the socket inner conductor 4 and the right end surface of the socket outer conductor 3; that is, the socket inner conductor will be inside the socket outer conductor and will not be exposed.
[0036] The right end of the plug inner conductor 6 is coaxially arranged inside the plug outer conductor 5, and the left end of the plug inner conductor 6 is arranged outside the left side of the plug outer conductor 5;
[0037] The right end of the socket inner conductor 4 is provided with a coaxially arranged second jack 10, and the left end of the plug inner conductor 6 is inserted into the second jack 10. In this way, the plug inner conductor is directly inserted into the second jack, so that the plug inner conductor and the socket inner conductor are plugged in and the electrical connection between the two is achieved.
[0038] See also Figures 1 to 3 As shown, an annular protrusion 11 is provided on the middle outer surface of the plug inner conductor 6, and the left end surface of the annular protrusion 11 abuts against the right end surface of the socket inner conductor 4.
[0039] The annular protrusion is arranged on the left side outside of the plug outer conductor.
[0040] In this way, while the outer surface of the inner conductor of the plug is in radial contact with the second plug hole of the inner conductor of the socket, the annular protrusion can also make end surface contact with the inner conductor of the socket. Such double contact can effectively ensure electrical connection performance.
[0041] See also Figure 1 As shown, a tapered guide hole 12 is provided on the right inner surface of the first jack 9, the outer diameter of the right end of the tapered guide hole 12 is larger than the outer diameter of the left end of the tapered guide hole 12, the right end of the tapered guide hole 12 is connected to the right end surface of the socket outer conductor 3, and the left end of the tapered guide hole 12 is connected to the inner surface of the first jack 9.
[0042] In this embodiment, the tapered guide hole is provided so that when the spring piece is inserted into the first plug hole, the spring piece can be guided through the tapered guide hole, and the left end of the spring piece is pressed inward, so that the outer diameter of the left end of the annular structure composed of multiple spring pieces is reduced, so that the spring piece can smoothly enter the first plug hole, and then the outer conductor of the plug is inserted into the first plug hole, so as to realize the quick plug-in connection between the outer conductor of the plug and the outer conductor of the socket.
[0043] See also Figure 2 As shown, an annular groove 13 is provided on the left outer surface of the plug 1, and the annular groove 13 is arranged outside the outer conductor 5 of the plug. A sealing ring 14 is installed in the annular groove 13, and the left side of the sealing ring 14 is against the right side of the socket 2.
[0044] The sealing ring adopts an elastic sealing ring. Through the setting of the annular groove and the sealing ring, after the plug and the socket are plugged in, the connection between the plug and the socket can be sealed to prevent external water and dust from entering the outer conductor of the plug and the outer conductor of the socket from the connection, thereby ensuring the electrical connection performance and stability of use.
[0045] See also Figure 2 , 3 As shown, the outer diameter of the annular structure formed by the plurality of arc-shaped protrusions is smaller than the inner diameter of the outer conductor of the socket, and the outer conductor of the plug is tightly matched with the inner conductor of the socket;
[0046] The inner conductor of the plug is tightly matched with the inner conductor of the socket.
[0047] The tight fit between the two can ensure radial contact, thereby ensuring electrical connection performance.
