Description

Cable Connector Combination

【Technical field】

The utility model relates to a cable connector combination, in particular to a cable connector combination for transmitting radio frequency signals.

Background technique

For the technology related to this case, please refer to US Patent No. 4,580,862, which discloses a cable connector assembly with a plug connector mating end provided with a hollow first housing in which the plug terminals are accommodated. The mating end of the mated socket connector is provided with a second housing, and the socket terminal is accommodated in the second housing, and the outer periphery of the second housing is provided with threads. When docking, the second housing of the socket connector is plugged into the first housing of the plug connector, and the plug terminal is docked with the socket terminal at the same time, and the thread on the periphery of the second housing is locked with the inner wall of the first housing to Ensure reliable connection between the two. However, since the plug terminal and the socket terminal are initially plugged directly, and no corresponding guiding device is provided therebetween, during the docking process of the plug and socket connectors, if one of them deviates slightly on the docking axis, it will It may cause the terminals of the other connector to be bent and damaged. This situation is more serious in radio frequency connectors, because radio frequency connectors require high precision, relatively small size, and low mechanical strength of terminals. The deviation of the direction is large, and the terminal is easily bent, and in severe cases, the terminal may be broken.

Of course, the industry has also proposed corresponding solutions. For related content, please refer to US Patent No. 5,611,707, which discloses a connector combination including a plug connector and a socket connector. Among them, the plug connector is provided with an elastic socket between the outer shell and the insulating body holding the terminal. There is a slope at the end and the slope of the inner wall of the shielding shell forms a groove for receiving the convex ring. When plugging in, the connection between the elastic socket and the insulating sleeve provides a pre-guided positive position for the terminals, so that the terminals can be reliably docked with each other. ; At the same time, the retaining force of the butt connector is increased by the buckle between the convex ring and the groove. However, the protruding ring of the plug connector engages directly with the groove provided at the end of the insulating sleeve. In this way, when the plug connector is subjected to a force perpendicular to the direction of the insertion axis, it may cause the elastic insert to generate a large torque at the junction of the convex ring and the groove, so that elastic deformation occurs, which may further make the plug terminal relative to the socket. The terminals are deflected and the plug or socket terminals are bent and damaged. In addition, a large force is also required to separate the mating plug and socket.

【Content of invention】

The purpose of the utility model is to provide a cable connector combination which can make two electrical connectors stably and safely docked and can easily separate the two docked connectors.

The purpose of this utility model is achieved in this way: the utility model includes first and second connectors, wherein the first connector includes a first housing, a first insulator, a first terminal assembled in the first insulator and an assembly The elastic sleeve is arranged between the first shell and the first insulator, the free end of the elastic sleeve is protruded with a buckle ring, and the protruding ring is provided with at least a pair of drivable rings at a certain distance from its free end. The pressure handle retracted by the elastic sleeve; and the second connector includes a second housing, a second insulator, and a second terminal assembled in the second insulator, and the inner wall of the second housing is provided with a buckle ring. snap slot.

The utility model not only can increase the holding force of the joint between the two connectors through the cooperation between the buckle ring and the buckle groove, but also can reduce the diameter of the elastic sleeve when plugging and unplugging by pressing the handle against each other, so that The two connectors mate smoothly and reliably and can be easily separated.
