Please refer to FIG. 1 , which is a three-dimensional view of the first joint and the second joint of the present invention without being connected. The utility model provides a butt joint structure of a push-lock type electrical connector, which includes a first joint 1, a second joint 2 connected with the first joint 1, and a joint between the first joint 1 and the second joint 2 When docking, provide latches 3 that are locked to each other (as shown in Figure 2); where:

The first joint 1 includes a first body 10 and a first docking portion 11 protruding from the front end of the first body 10, wherein the rear end of the first body 10 can be used to connect a cable 100, and the first docking portion A plurality of plug terminals 12 can be provided in the part 11 for telecommunications connection when docking with the above-mentioned second connector 2 . In addition, a card slot 110 is provided on the outer wall of the first docking portion 11. The card slot 110 can be annular and surround the outer wall of the first docking portion 11. The section of the card slot 110 can be It is a concave trapezoid, so as to have a first slot slope 111 and a second slot slope 112 .

The second connector 2 is used to connect with the above-mentioned first connector 1 . As shown in FIG. 2 and FIG. 3 , the second joint 2 includes a second body 20 , a sliding shell 21 set outside the second body 20 , and a sliding shell 21 set between the second body 20 and the sliding shell 21 . The elastic component 22, wherein the rear end of the second body 20 can also be used to connect another cable 200, and the front end of the second body 20 has a second docking portion 201, and the second docking portion 201 is provided with a matching first The first docking portion 11 of the connector 1 is inserted into the socket 202 for relative connection between the first connector 1 and the second connector 2 . In addition, the sliding housing 21 can be pushed toward the rear end by the human hand through the elastic component 22 , and can return to the original position by the elastic force of the elastic component 22 after the human hand releases the pushing force.

Please also refer to Fig. 4 and Fig. 5, the utility model is mainly provided with the locking member 3 on the second joint 2, so that when the first joint 1 and the second joint 2 are docked, the locking member 3 3 Provide further locking between the two to prevent separation. The locking member 3 is arranged on the second docking portion 201 of the second joint 2, and is located between the second body 20 and the sliding housing 21; in the embodiment of the utility model, the locking member 3 It includes a ring body 30 and one or more locking elastic arms 31 extending axially from the ring body 30. The ring body 30 can be in the form of a C-shaped ring for the locking member 3 to be clamped. On the second docking portion 201, at least one locking hole 203 is provided on the second docking portion 201, and each locking elastic arm 31 has a locking portion whose front end is opposite to the inner edge of the locking hole 203. 32 , and a locking block 33 protruding from each locking portion 32 toward the socket 202 of the second docking portion 201 , and there is an elastic distance S between the locking block 33 and the locking elastic arm 31 . In addition, the cross-section of the block 33 can be a protruding trapezoid to have a first block slope 330 and a second block slope 331 .

Thereby, as shown in FIG. 5 and FIG. 6 , since there is an elastic distance S between the block 33 of the lock member 3 and the elastic arm 31 of the lock, when the first joint 1 and the second joint 2 are in contact with each other, the lock The block 33 will be pushed by the first docking part 11 of the first joint 1 and deform toward the elastic distance S, so that the first joint 11 can be completely inserted into the socket 202 so that the first joint 1 and the second joint 2 are connected to each other without pushing the sliding housing 2 of the second joint 2. Therefore, the utility model can be convenient for users to install or maintain, so as to save time spent on operations.

As shown in FIG. 7 , when the first docking portion 11 of the first connector 1 is fully inserted into the socket 202 , the block 33 of the locking member 3 can pass through the slot through the first block slope 330 . 110 of the first slot slope 111 slides into it, so that the block 33 is snapped on the slot 110 of the first docking portion 11 and because the inner wall of the sliding housing 21 is still continuously against the locking portion 32 to prevent the locking block 33 from detaching from the locking slot 110 . In more detail, since the locking portion 32 falls into the locking hole 203 so that its front end 320 is relative to the inner edge of the locking hole 203 , and the outer side 321 of the locking portion 32 is limited by the resistance of the inner wall of the sliding housing 21 Therefore, the locking elastic arm 31 does not have any space for outward deformation or bending to make the block 33 break away from the slot 110, so that the first joint 1 and the second joint 2 can have high tensile strength when they are docked. And to prevent separation, and because the locking member 3 is located between the positions where the first joint 1 and the second joint 2 are docked, it does not occupy external space and can be applied to occasions with limited space.

In addition, as shown in FIG. 8, when the first joint 1 and the second joint 2 are to be separated, it is only necessary to push the sliding housing 21 of the second joint 2 backward and separate the two through the pulling force of the human hand; In the example of the utility model, the inner wall of the front end of the sliding housing 21 is provided with a retreat groove 210 with a larger diameter. Therefore, when the first docking portion 11 of the first joint 1 is separated from the socket 202 of the second joint 2, the first docking portion 11 can push the block 33 of the locking member 3 out of the slot 110 and push the block 33 is pushed radially outward to deform the locking elastic arm 31 and allow the locking part 32 to retreat to the retreat groove 210, and at the same time, the clamping block 33 can also be shortened and locked with the elastic distance S The distance between the elastic arms 31 is convenient for deformation, so that the first docking portion 11 can quickly disengage from the socket 202 to separate the first connector 1 and the second connector 2 from each other.

Therefore, the butt joint structure of the push-lock electrical connector of the present invention can be obtained by the above-mentioned structural composition.

The above-mentioned embodiments are only preferred embodiments for fully illustrating the utility model, and the protection scope of the utility model is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art on the basis of the present utility model are all within the protection scope of the present utility model.
