Detailed ways

As shown in FIG. 1 a to FIG. 2 , it is an embodiment of the electrical connector of the present invention, which includes a male seat 1 and a female seat 2 . Wherein, the male seat 1 and the female seat 2 are both made of insulating materials, such as plastic injection-molded shells, of course, other materials and processes can also be used for molding.

An inserting protrusion 11 protrudes axially from the inner side of the male seat 1 ; and the female seat 2 adjacent to the inserting protrusion 11 defines an engaging recess 21 in the axial direction for the inserting protrusion 11 to be inserted and connected. The male seat 1 and the female seat 2 are axially respectively provided with positioning grooves 12 and 22 opposite to each other for the positioning and insertion of conventional contact terminals and pins (not shown). Therefore, when the insertion protrusion 11 of the male seat 1 is inserted into the engagement groove 21 of the female seat 2, the contact terminals and the pins are in contact with each other to form an electrical connection, which is a well-known technology in the art. I won't go into details here.

Wherein, a sealing ring 13 is sleeved on the periphery of the insertion protrusion 11, and the sealing ring 13 can be made of polymer elastic material, such as silica gel, rubber, etc., to prevent foreign matter, such as liquid or dust, from entering the electrical connector.

The male seat 1 and the inner side of the female seat 2 are oppositely provided with a buckle mechanism 3, the buckle mechanism 3 is arranged at an appropriate position of the male seat 1, for example, a tongue 31 is axially extended on the top surface of the male seat 1, and the tongue The fixed end 311 of 31 is radially integrally connected to the top surface of the male seat 1, so that the axial movable end 312 of the other end can be elevated, and a buckle groove 313 is opened radially to form a first buckle mechanism. Moreover, an abutment groove 314 is axially recessed on the right bottom surface of the buckle groove 313 of the tongue piece 31 , and a guiding slope is formed on the outside of the abutment groove 314 . In addition, for the convenience of pressing the tongue piece 31 , a pressing handle 315 is radially connected to the top surface of the buckle groove 313 approximately in the middle.

And the appropriate position of the female base 2, for example, a "ㄇ"-shaped top cover 32 protrudes from the top surface, and a slot 321 is formed axially inside it, and a buckle hook is radially protruded from the inner surface of the top wall of the top cover 32 corresponding to the position of the buckle groove 313. 322 ; and in order to make the buckle 322 have the function of elastic radial movement, the top wall of the top cover 32 defines a "U" shaped groove 323 radially around the buckle 321 . Wherein, the extension wall 324 on the right side of the top cover 32 is connected to one end of an inverted "L"-shaped movable handle 33, and the bottom edge of the extension wall 324 corresponds to the bottom surface on the right side of the tongue 31 and extends horizontally inwards to the top surface of the female seat 2. The support 331 is separated so that the support 331 can support the bottom surface of the right side of the tongue 31 to form a second buckle mechanism.

Wherein, the support member 331 is axially recessed with a locking groove 332 formed on the inner side to form a guiding slope, so that the abutment groove 314 on the bottom surface of the right side of the tongue 31 is supported on the support member 331 and buckled in the locking groove 332 Inside. Further, in order to push the handle 33 conveniently, the other end of the handle 33 , that is, the pushing end of the left side wall is provided with several parallel and protruding ribs 333 to facilitate pushing the handle 33 .

Please refer to Figure 1a, Figure 1b, Figure 2, Figure 3a and Figure 3b. When the electrical connector needs to form an electrical connection, it is only necessary to connect the male seat 1 and the female seat 2, that is, the insertion protrusion 11 of the male seat 1 Insert it into the joint recess 21 of the female base 2. At this time, the tongue 31 passes through the handle 33 first, and overlaps the bottom surface on the right side on the support 331, so that the abutment groove 314 and the snap-in groove 332 form a buckle; then , the tongue 31 continues to be inserted into the slot 321 of the top cover 32, so that the movable end of the tongue 31 touches the guiding slope of the buckle 322, so that the buckle 322 moves up elastically until the buckle groove 313 passes through the buckle 322, so that The buckle 322 loses the support of the tongue 31, and returns to its original position, and is further buckled in the slot 321. At this time, the male seat 1 and the female seat 2 cannot be axially separated, and a double buckle mechanism is formed; at the same time , The contact terminals of the male seat 1 and the female seat 2 are in contact with each other and form an electrical connection state.

As shown in Figure 4a, if the male seat 1 and the female seat 2 of the electrical connector are to be separated, the user only needs to push the rib 333 on one side of the handle 33 forward with one hand, so that the other side takes the extension wall 324 as a fulcrum , and the support member 331 is offset and rotated counterclockwise, and the guide slope of the engaging groove 332 of the support member 331 is disengaged along the guide slope of the abutting groove 314 on the bottom surface of the right side of the tongue 31, so that the tongue As shown in FIG. 4 b , the bottom surface on the right side of the sheet 31 loses the support of the supporting member 331 and has the function of elastically pressing down.

Next, as shown in FIG. 4c, the user presses down the pressing handle 315 on the top surface of the tongue 31 with the other hand, so that the buckle groove 313 is disengaged from the catch of the buckle hook 322, and the male seat 1 can be pulled forward, so that the socket The convex part 11 is gradually separated from the engaging concave part 21 of the female seat 2; until the male seat 1 and the female seat 2 are completely separated, that is, the separated state shown in Figure 4d. At this time, the contact terminals of the male seat 1 and the female seat 2 are connected to the The pins are also in a separated electrical disconnection state.

Further, the tongue piece 31, the top cover 32 and the handle 33 with one end connected to the extension wall 324 on one side of the top cover 32 are respectively arranged on the top surface of the male seat 1 and the female seat 2, but it is not limited to this, that is, the tongue The sheet 31 can be placed on the top surface of the female seat 2, while the top cover 32 and the handle 33 can be arranged on the top surface of the male seat 1, so as to obtain a double unlocking buckle effect, which is also the solution claimed by the present invention.

Therefore, through the implementation of the present invention, the enhanced effect is that the buckle mechanism is integrally connected with a handle on the extension wall in front of the slot opening of the top cover, and when the pushing end of one end of the handle is pushed, the support at the other end Due to the rotation, the part is moved away from the bottom surface of the same side of the tongue, so that the tongue loses the support of the supporting part, and can be pressed down, and the first unlocking mechanism is formed; in addition, by pressing down the tongue, the hook that makes its buckle groove disengage to form a second unlocking mechanism. Therefore, when the tongue is subjected to an external force, such as vibration, it will not cause the unlocked state where the hook and the groove are easily disengaged, which can be regarded as a great feature of similar items.

What is disclosed in the present invention is one of the preferred embodiments, and all partial changes or modifications derived from the technical idea of the present invention and easily deduced by those skilled in the art will not depart from the scope of the patent protection of the present invention.
