As shown in fig. 1-8, the utility model provides a joint formula electric connector, include:

a plug and a socket, the plug comprises a first housing 1 and a fixing member 2.

The first casing 1 includes two first cylindrical portions 101. The two first cylindrical portions 101 are arranged side by side and fixedly connected by a first connecting portion 102. The fixing member 2 has two first through holes adapted to pass the electric wire therethrough. The fixing member 2 is fixed to the tail of the first housing 1 in a clamping manner, and the two first through holes are coaxial with the two first cylindrical portions 101 respectively.

The plug further comprises a latch 3, the latch 3 comprising two side plates 301 and a connecting plate 302. The two side plates 301 are located on both sides of the first casing 1 and respectively correspond to the two first cylindrical portions 101, and the two side plates 301 are fixedly connected by a connecting plate 302.

A second locking column 1011 extends from the outer wall of the first cylindrical portion 101, and the axis of the second locking column 1011 is perpendicular to the axis of the first cylindrical portion 101. The side plate 301 is provided with a second through hole 3013, and the second locking column 1011 is rotatably inserted into the second through hole 3013. In this way, the latch 3 is hinged to the first housing 1 with the hinge axis perpendicular to the axis of the first cylindrical portion 101.

The socket comprises a second housing 4, the second housing 4 comprising two second cylindrical portions 401, the two second cylindrical portions 401 being arranged side by side and being fixedly connected by a second connecting portion 402. The second cylindrical portion 401 has a first stopper 4011 protruding therefrom.

One surface of the side plate 301 facing the first housing 1 is provided with a sliding slot 3011 adapted to accommodate the sliding of the first locking post 4011, and a notch 3012 communicating with the sliding slot 3011 from the edge of the side plate 301.

When the locking piece 3 rotates to the first position, the position of the gap 3012 is suitable for the first locking pillar 4011 to pass through the gap 3012 when the socket and the plug are plugged. After rotating 3 first positions with the latch fitting, insert the socket and close with the plug, at this in-process, first card post 4011 passes breach 3012 and gets into spout 3011, rotate latch fitting 3 next, at this in-process, first card post 4011 slides in spout 3011, when latch fitting 3 rotates to the second position, first card post 4011 is no longer aimed at to breach 3012, because spout 3011 is to the limiting displacement of first card post 4011 this moment, consequently can't extract the separation with plug and socket.

In this embodiment, the fastening manner of the fixing member 2 and the first housing 1 is specifically as follows: the fixing member 2 includes two sleeving portions 201, the two sleeving portions 201 are fixedly connected by a third connecting portion 202, and the two sleeving portions 201 correspond to the two first cylindrical portions 101 respectively.

The sleeve 201 includes a first sleeve 2011 and a second sleeve 2012, an inner diameter of the first sleeve 2011 is smaller than an inner diameter of the second sleeve 2012, and the first sleeve 2011 and the second sleeve 2012 are coaxially fixed by a connection ring 2014. The inner bore of the first sleeve 2011 is the first through hole.

A plurality of second protrusions 1016 are protruded from the outer wall of the first cylindrical part 101 at positions near the rear thereof.

The second sleeve 2012 is provided with a plurality of fastening holes 2013, and the fastening holes 2013 are in one-to-one correspondence with the second protrusions 1016. The second sleeve 2012 is sleeved on the corresponding first cylindrical portion 101, and the fastening hole 2013 is fastened on the corresponding second protruding portion 1016.

The plug further comprises a first rubber core, and the first rubber core is arranged in the first cylindrical part 101 in a plugged mode. The first rubber core is provided with a first inserting hole, and an anode contact element (namely a contact pin) is inserted into the first inserting hole.

The socket further comprises a second rubber core, and the second rubber core is arranged in the second cylindrical part 401 in a plugged mode. The second rubber core is provided with a second inserting hole, and a cathode contact element (namely an inserting hole) is inserted into the second inserting hole.

When the plug of the clamping type electric connector is used for wiring, the electric wire needs to pass through the first through hole of the sleeving piece, then the electric wire is sleeved with the waterproof ring, then the end part of the electric wire is inserted into the tail part of the first cylindrical part 101, the end part of the conductive core of the electric wire is electrically connected with the anode contact element, finally the second sleeve 2012 is sleeved on the corresponding first cylindrical part 101, and the buckling hole 2013 is buckled on the corresponding second bulge 1016. Because the diameter of first sleeve 2011 is less than the diameter of second sleeve 2012, first sleeve 2011 has the effect of blockking the waterproof circle, avoids waterproof circle to fall out.

In the prior art, the fixing piece 2 and the plug are connected through threads, but the threads are connected to enable the risk of loosening and falling off, and the threads are connected in a mode so as to be convenient to detach, but in the actual use process, the fixing piece is often only required to be installed once, and the fixing piece is not detached. Therefore, in this embodiment, the fixing member 2 is connected with the first housing 1 in a clamping manner, so that the installation efficiency is higher compared with the threaded connection manner in the prior art, and the clamping manner is not easy to loosen.

According to a further embodiment, the outer wall of the first cylindrical part 101 also projects with a first projection 1013 towards the side plate 301. The first protrusion 1013 further has a first protrusion 1014 and a second protrusion 1015. The side plate 301 is further provided with a third through hole 3015.

When the latch 3 is rotated to the first position, the first protrusion 1014 is inserted into the third through hole 3015. When the latch 3 rotates to the second position, the second protrusion 1015 is inserted into the third through hole 3015.

In the rotation process of the locking piece 3, when the first protrusion 1014 or the second protrusion 1015 is inserted into the third through hole 3015, a sound and a resistance are generated to prompt the user that the locking piece 3 rotates to the first position or the second position.

According to another embodiment, a hook 3021 is further fixed to a surface of the connection plate 302 facing the first housing 1. The first housing 1 further has a hooking portion 103 adapted to be hooked by the hook 3021, and the hooking portion 103 is located between the two first cylindrical portions 101 and integrally connected to the first housing 1. When the locking member 3 rotates to the second position, the hook 3021 hooks the hooking portion 103.

After the plug is inserted and closed with the socket, with the locking piece 3 locking in the second position, avoid locking piece 3 rotatory to first position back plug and socket pine to take off.

According to another embodiment, a protrusion 1012 radially protrudes from the outer wall of the second latching post 1011, and the protrusion 1012 is disposed near the end of the second latching post 1011. The inner wall of the second through hole 3013 is further opened with a groove 3014 for the protrusion 1012 to pass through.

When the first housing 1 is assembled with the locking member 3, the protruding portion 1012 is positioned corresponding to the recess 3014, and then the second locking column 1011 is extended into the second through hole 3013, and after the protruding portion 1012 of the second locking column 1011 extends out of the second through hole 3013, the second locking column 1011 is rotatably engaged with the second through hole 3013.
