Description

Connector and connector assembly

Technical Field

The utility model relates to a connector for realize the break-make of circuit.

Background

Connectors are used in a wide variety of applications, often in the form of connector assemblies that include a plug connector and a receptacle connector that mate together in use. The plug connector and the socket connector are connected in a plugging mode comprising threaded connection, bayonet connection and locking ball connection. The threaded connection is that one of the plug connector and the socket connector is provided with an external thread, and the other one is provided with an internal thread; the bayonet connection is that a spiral groove is arranged on the plug connector or the socket connector, and a locking nail is arranged on the other plug connector or the socket connector and is locked through the spiral groove; the lock ball is connected to a connector disclosed in patent document No. CN 102820587A.

Plug and receptacle connectors sometimes require high sealing requirements. For example, with the development of 5G communication technology, the requirement for the reliability of the sealing protection level of the interface of the communication equipment is higher and higher, and the following requirements are generally required: 1. the fixed end connector (socket connector) of the equipment needs to realize open air sealing, namely liquid can not enter the equipment from the interface when the headstock (the plug connector and the socket connector) is in a non-plugging state, and whether the socket can meet the requirement or not is judged through air sealing test. Even, the following requirements may be present: 2. the free end connector (plug connector) also needs to meet the requirement of open air sealing, so that the possibility that liquid enters the plugging end face of the connector from the damaged part of the cable sheath can be avoided; in addition, when the plug is not in the plugging state, the plugging surface is accidentally met with water, and water cannot penetrate into the tail of the plug, so that the water is conveniently and quickly drained, and the redundancy of the protection capability is further improved.

However, if the plug connector adopts a conventional non-open sealing structure, the possibility that liquid enters the plug base plugging interface from the damaged cable or even enters the inside of the device cannot be avoided, the possibility that liquid enters the plug from the plug plugging surface or even enters the inside of the cable cannot be prevented, and the sealing performance is difficult to meet some specific requirements.

In addition, both threaded and bayonet connections require the operator to manually rotate the locking/unlocking feature, which requires sufficient space around the locking/unlocking feature to accommodate finger movement. To ensure a reliable connection, the locking and unlocking torque is usually high, sometimes requiring the operator even to wear anti-slip gloves or use a wrench. The operative space between the connectors is therefore usually much greater than the finger thickness for the operator to operate. Therefore, the installation density between the interfaces of the adjacent connectors is difficult to be improved, and the overall miniaturization design of the communication equipment is influenced. Moreover, since the coefficient of friction of the connector surface is generally small, an operator needs to additionally apply a large force to ensure slip prevention even when wearing slip-resistant gloves, and the experience of handling is generally poor. Especially threaded connection closes the number of turns soon more, has reduced the efficiency that the operator inserted the connector, and the convenience is relatively poor. For threaded connection, the arrangement of a thread anti-loosening measure is also required to be considered, and the connector is provided with an anti-loosening mechanism, and the connector is inserted into a heat-shrinkable tube which is sleeved in place, so that the miniaturization of the size of the connector and the convenience of operation are affected. The existing equipment miniaturization trend and equipment interface densification trend are prominent, the operation space for inserting and combining the head seat is smaller and smaller, the operation difficulty is improved, the possibility that an operator cannot insert and combine in place or misjudge the inserting and combining in place is increased, and therefore sealing failure of the interface is easily caused.

The utility model discloses embodiment 2 of well connector:

as shown in fig. 5 and 6, the receptacle connector of the connector in the present embodiment is adapted to the plug connector in embodiment 1. The socket connector comprises a socket shell 51 and a socket side plug part 52, wherein the socket shell 51 is a square disc shell and is provided with an inner hole, and the socket side plug part 52 is arranged in the inner hole of the square disc shell.

The square plate shell is provided with a lock ball hole, a lock ball 53 is arranged in the lock ball hole, and a lock ball structure is formed at the end of the socket connector and is matched with the lock ball structure on the plug connector.

The socket-side plug member 52 includes a socket-side insulator 54, a socket-side sealing rubber gasket 55 and an insulating pressure plate 56, which are sequentially arranged in the front-rear direction, and the three structures are similar to the plug-side plug member 30, and also have through holes penetrating in the front-rear direction for the socket contact 510 to be embedded therein, and similarly, the socket-side sealing rubber gasket 55 is provided with a sealing matching hole and a sealing outer peripheral surface; the insulating pressing plate 56 is a socket side righting body, and a backward step surface is arranged on the rear end surface and used for being in blocking fit with the socket core body clamp spring 57.

In addition, a circumferential color tape 59 is further arranged on the outer peripheral surface of the socket shell 51, the circumferential color tape 59 extends along the circumferential direction and is arranged at a set position along the axial direction of the socket shell 51, and when the plug connector is plugged in place, the circumferential color tape 59 is shielded by the plug shell of the plug connector to indicate that the plug connector and the socket connector are plugged in place.

Due to the fact that the socket side sealing rubber gasket 55 is arranged, after the socket connector is installed in place on the panel of the equipment, even if the socket connector is in a non-plugging state, external water cannot enter the equipment, and the protection performance of the equipment is improved. The structure also enables the socket connector to select a common dustproof cover without a matched waterproof sealing cover. In this embodiment, the receptacle connector further includes a receptacle dust cap 511, which is only used for dust protection before the connector assembly is plugged, and does not need to satisfy the waterproof requirement.

In the socket connector, the diameter of the part where the socket contact 510 is matched with the sealing colloid and the center distance of the socket contact 510 are respectively the same as the diameter of the plug contact 34 and the center distance of the contact.

Referring to fig. 7 and 8, when the plug-in locking is required, only the straight sleeve 11 or the tail nut 14 needs to be pushed, and at this time, the locking ball 53 at the socket end is jacked up by the outer wall of the front end of the spline housing and contacts with the step surface of the connecting nut 13 to force the connecting nut 13 to axially displace relative to the spline housing. When the ring groove 25 of the spline housing moves to the position right below the lock ball 53, the lock ball 53 is displaced by the reaction force of the connecting nut 13 and falls into the ring groove 25; the coupling nut 13 is now rapidly returned to its original position under the force of the spring 22. In a locking state, the locking ball 53 is positioned in the annular groove 25 of the spline housing and is blocked by the inner wall of the connecting nut 13, and the pre-compression force of the spring 22 ensures that the connecting nut 13 does not retreat, so that stable and reliable locking is realized. Before the socket is inserted in place, the circumferential color band 59 at the socket end is exposed and can be seen; after the plug-in position is achieved, the circumferential color band 59 is covered by the connecting nut 13, and the in-position mark is obvious.

When the unlocking is needed, only the connecting nut 13 needs to be pulled successively, the diameter of the inner wall surface of the connecting nut 13 contacted with the locking ball 53 is increased, the spline shell is forced by the spring 22 to move in the same direction, and the annular groove 25 of the spline shell pushes the locking ball 53 to ascend and finally separate from the annular groove 25, so that the unlocking is realized. In conclusion, the push-pull locking mode has a simple structure, is stable and reliable in looseness prevention, does not need an operation torsion space, and is convenient for meeting the requirements of equipment miniaturization and interface densification; the push-pull locking mode is simple to operate and can be in place in one step, the insertion reliability is more prominent in a narrow installation space compared with connection modes such as threads and bayonets, and the sealing failure risk caused by the fact that the insertion is not in place can be greatly reduced.
