Description

Technical Field

[0001] The invention relates to a plug-in connector, in particular to a connector which is convenient to operate. Background Art

[0002] The plug-in connector is a plug-in connector that is inserted into the plug-in sleeve of the socket to achieve electrical conduction and current transmission. It is commonly used in plug-in charging structures. After the traditional plug and socket are plugged in, the friction between the two is used to achieve fixed positioning. After long-term use of this type of connector, the friction between the plug and the socket will gradually decrease, resulting in poor connection stability and easy circuit breakage. Therefore, in order to increase the service life, the friction resistance between the plug and the socket needs to be increased, which consumes effort during plugging and unplugging, and is easy to damage the terminals. This structure is also prone to the plug being pulled out due to external force when the plug and the socket are plugged in, causing the current transmission to be interrupted;

[0003] In order to improve the plugging stability of the plug-in connector, a locking structure is currently provided on the plug and socket of the plug-in connector. When the plug and the socket are plugged in, the plug and the socket are locked and connected by the locking structure, thereby improving the connection stability between the plug and the socket. The most convenient structure in the existing locking structure is to provide a handle on the plug and a buckling surface on the socket, and the raised part on the handle passes through the avoidance opening on the plug shell to buckle and position with the buckling surface on the socket. However, the surface of the raised part on the existing handle contacts the buckling surface on the socket through a concave arc surface, and after being pressed to unlock, it needs to avoid the side wall of the avoidance opening of the plug shell. The buckling surface between the raised part on the handle and the socket is limited, so the head seat holding force provided by this type of locking structure is limited, and the plug can be pulled out by force.

[0024] Embodiment: A conveniently operated connector comprises a socket 1 and a plug 2, wherein one end of the socket 1 is provided with a plug sleeve 11, and one end of the plug 2 is provided with a plug post 21, wherein the plug post 21 can be inserted into the plug sleeve 11, and a first buckle is provided on the outer circumferential wall of the plug sleeve 11, and a handle 3 is installed on the plug 2 to slide a set distance, and an elastic retaining structure 4 is also provided on the plug 2 to provide the handle 3 with movement in the locking direction, and an elastic lock buckle 31 is provided on the handle 3 to be able to elastically swing along the radial direction of the plug post 21, so that A second buckle is formed on the free end of the elastic lock buckle 31. When the handle 3 is in the locked position, the second buckle at the free end of the elastic lock buckle 31 can be engaged with the first buckle on the plug-in sleeve 11 sleeved on the outside of the plug-in column 21 to prevent the plug-in sleeve 11 from being separated from the plug-in column 21. A linkage mechanism is also provided on the plug 2. When the handle 3 moves in the unlocking direction, the linkage mechanism drives the elastic lock buckle 31 to swing. When the handle 3 moves to the unlocking position, the linkage mechanism causes the second buckle at the upper end of the elastic lock buckle 31 to disengage from the first buckle on the plug-in sleeve 11.

[0025] The handle 3 on the plug 2 is maintained in a locked state under the action of the elastic retaining structure 4. When the plug post 21 of the plug 2 is inserted into the plug sleeve 11 of the socket 1 to achieve electrical connection, the second buckle on the elastic lock buckle 31 of the handle 3 automatically engages with the first buckle on the circumferential outer wall of the plug sleeve 11 under the elastic force of the elastic cantilever structure of the elastic lock buckle 31, preventing the plug sleeve 11 from sliding axially and disengaging from the plug post 21, thereby realizing the automatic locking function of the plug 2 and the socket 1.

[0026] When it is necessary to unlock and separate the plug 2 from the socket 1, it is only necessary to slide the handle 3, and under the drive of the linkage mechanism, the elastic lock buckle 31 will swing elastically, so that the second buckle at the free end of the elastic lock buckle 31 is disengaged from the first buckle on the circumferential outer wall of the plug sleeve 11, and the plug 2 can be easily pulled out from the socket 1. This structure is easy to operate, improves the electrical connection stability when the plug 2 and the socket 1 are plugged in, and facilitates quick unlocking of the two.

[0027] After the plug 2 is unplugged from the socket 1 , the handle 3 loses the external force and automatically returns to the locked position under the action of the elastic retaining structure 4 .

[0028] The linkage mechanism includes an inclined surface 22 provided on the plug 2 and a protrusion 311 provided on the side wall of the elastic lock buckle 31. When the handle 3 slides on the plug 2, the protrusion 311 on the elastic lock buckle 31 slides along the inclined surface 22 on the plug 2, forcing the elastic lock buckle 31 to swing. When the handle 3 slides, the elastic lock buckle 31 slides synchronously with the handle 3, and the protrusion 311 on the elastic lock buckle 31 slides along the inclined surface 22 on the side wall of the plug 2, thereby forcing the elastic lock buckle 31 to swing elastically, wherein the protrusion 311 on the elastic lock buckle 31 preferably contacts the inclined surface 22 on the plug 2 through the arc surface or inclined surface 22 to ensure smooth sliding.

[0029] The plug-in column 21 of the plug 2 is also coaxially provided with a circle of insulating protective sleeve 23 on the outside, and the plug-in sleeve 11 of the socket 1 can be accommodated in the annular gap between the insulating protective sleeve 23 and the plug-in column 21. The side wall of the insulating protective sleeve 23 of the plug 2 is provided with a hollow notch 231, and the second buckle end of the elastic lock buckle 31 can enter the annular gap through the hollow notch 231 and be buckled and connected with the first buckle on the plug-in sleeve 11. When the plug-in column 21 of the plug 2 is inserted into the plug-in sleeve 11 of the socket 1, the plug-in sleeve 11 on the socket 1 is inserted into the insulating protective sleeve 23 of the plug 2, so as to achieve insulation protection of the plug-in part, and can play a waterproof and dustproof effect, and ensure the use safety and current and signal transmission stability when the plug is connected. After the plug 2 is plugged into the socket 1, the second buckle on the elastic lock buckle 31 enters the annular gap through the hollow notch 231 of the insulating protective sleeve 23, and then locks the plug-in sleeve 11 on the socket 1.

[0030] The first buckle on the outer circumferential wall of the plug sleeve 11 is a circle of flange 12 or groove arranged on the outer circumferential side of the end of the plug sleeve 11, and the second buckle on the free end of the elastic lock buckle 31 is a boss 312 arranged on the side wall of the free end of the elastic lock buckle 31. The boss 312 can stop the flange 12 on the outer circumferential side of the plug sleeve 11 or the inner wall of the groove to prevent the plug sleeve 11 from sliding axially along the plug column 21 and disengaging the plug 2. The locking function is achieved by the concave and convex blocking each other, and the locking function can also be achieved by hooking.

[0031] The middle part of the boss 312 along the sliding direction of the handle 3 is a straight surface tangent to the outer side surface of the plug sleeve 11 or the bottom surface of the groove. The two ends of the boss 312 along the sliding direction of the handle 3 are chamfered inclined surfaces 22. The hollow notch 231 on the side wall of the insulating protective sleeve 23 forms a stop surface on one side wall facing the locking direction of the handle 3. The boss 312 at the free end of the elastic lock buckle 31 stops on the stop surface on the side facing the locking direction. A flat surface is also formed on the outer side wall of the insulating protective sleeve 23. When the elastic lock buckle 31 is in the locked state, its side wall is flat on the flat surface. This structure is conducive to keeping the elastic lock buckle 31 in a stable position in the locked state, thereby improving the locking stability.

[0032] A handle accommodating cavity 24 is provided in the shell of the plug 2. The handle accommodating cavity 24 shares a side wall with the insulating protective sleeve 23. The hollow notch 231 connects the inner space of the insulating protective sleeve 23 with the handle accommodating cavity 24. The handle 3 can be slidably inserted in the handle accommodating cavity 24. Placing the handle 3 in the handle accommodating cavity 24 can protect the handle 3 and effectively prevent accidental touch.

[0033] The handle accommodating cavity 24 is further provided with a handle guide slot 241, and the handle 3 is further provided with a guide rod 32, which can be inserted into the handle guide slot 241 in a linearly sliding manner. The guide rod 32 slides back and forth in the handle guide slot 241 to achieve guidance and position limitation perpendicular to the sliding direction. The handle guide slot 241 can be a ring-shaped structure or an open groove-shaped structure, and the guide rod 32 is a columnar structure matching it.

[0034] The guide rod 32 is provided with an axially extending spring slot 321, the elastic member is a spring, the spring is inserted into the spring slot 321, one end of the spring is fixedly connected to the bottom surface of the spring slot 321, and the other end of the spring extends out of the opening of the spring slot 321 and is fixedly connected to the bottom surface of the handle guide slot 241. The above structure hides the spring between the guide column and the handle guide slot 241, saving space, and also plays a guiding role in the compression deformation of the spring.

[0035] The handle 3 is also provided with an outwardly protruding limiting protrusion 33 or a long groove-shaped limiting sliding groove, and the inner wall of the handle accommodating cavity 24 is provided with a long groove-shaped limiting sliding groove or an outwardly protruding limiting protrusion 33, and the limiting protrusion 33 can be slidably inserted in the limiting sliding groove, and the two side walls of the limiting protrusion 33 along the sliding direction of the handle 3 are stopped on the inner wall of the limiting groove to limit the sliding distance. The limiting protrusion 33 cooperates with the long strip-shaped limiting sliding groove to limit the sliding distance of the handle 3, thereby preventing the handle 3 from being separated from the plug 2.

[0036] The handle accommodating cavity 24 is provided with a countersunk structure 25 with an expanded size at its opening, and an operating plate 34 that can be accommodated in the countersunk structure 25 is formed on the handle 3, and the root of the elastic lock buckle 31 is integrally formed on the operating plate 34. When unlocking the plug 2 and the socket 1, the operation plate 34 can be easily operated by simply pressing the thumb, and anti-slip patterns can be formed on the operating plate 34 to facilitate force application and achieve an anti-slip effect.
