Description

Technical Field

[0001] The utility model relates to the technical field of connector butt joint structures, in particular to a cable connector butt joint buckling structure. Background Art

[0002] Existing cable connectors mainly achieve the purpose of transmitting power and / or electrical signals by plugging a first connector connected to a plurality of first cables and a second connector connected to a plurality of second cables. In order to avoid unexpected separation of the cable connector and interruption of power or electrical signals, a quick-connect push-pull method, such as a straight-arm snap-on type or an L-shaped snap-on type, is widely used in cable connectors; however,

[0003] The existing L-shaped buckle type cable connector has the following disadvantages: the width of the L-shaped buckle on one of the butt joints is exactly the same as the width of the plug on the other butt joint. Although the stability between the two joints is guaranteed, when the cable connected to one of the butt joints is subjected to external force, the cable drives the corresponding butt joint to rotate, so that the two butt joints are twisted with each other. This twisting force makes it easy for the butt joints to be squeezed and damaged by each other, thereby reducing their service life. Utility Model Content

[0004] In view of the problems existing in the existing cable connector butt-jointed buckling structure, the utility model is proposed.

[0005] Therefore, the purpose of the utility model is to provide a cable connector butt-jointing structure, which solves the problem that the width of the L-shaped buckle on one of the butt joints and the width of the plug-in on the other butt joint are exactly the same in the current L-shaped buckle type cable connector. Although the stability between the two joints is guaranteed, when the cable connected to one of the butt joints is subjected to external force, the cable drives the corresponding butt joint to rotate, thereby causing a mutual twisting trend between the two butt joints. This twisting trend will make the butt joints easily squeeze each other and be damaged, thereby reducing the service life.

[0006] In order to solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solutions:

[0007] A cable connector butt-jointed snap-fit ​​structure comprises a first pair of joints and a second pair of joints, wherein one end of the first pair of joints and the second pair of joints is respectively provided with a first butt joint portion and a second butt joint portion, the first butt joint portion is provided with a first snap-fit ​​groove, the second butt joint portion is provided with a first snap-fit, and the width of the first snap-fit ​​groove is greater than the width of the first snap-fit.

[0008] As a preferred solution of the cable connector docking and buckling structure described in the utility model, the second docking portion is composed of a first arc plate and a second arc plate that are staggered, and the first buckle is integrally formed with the second arc plate.

[0009] As a preferred solution of the cable connector docking and snap-fitting structure described in the utility model, a docking post is provided in the inner cavity of the first docking part, a docking tube is provided in the inner cavity of the second docking part, a wiring slot is provided on the docking post, and a wiring pin is provided in the docking tube.

[0010] As a preferred solution of the cable connector butt-jointed structure described in the utility model, the slot is composed of a connected slot and an open slot, and the size of the open slot is larger than the connection pin.

[0011] As a preferred solution of the cable connector butt-jointed buckling structure described in the utility model, wherein: an auxiliary arc block is integrally provided on the outer wall of the first butt joint portion, and an arc through hole is provided on the auxiliary arc block;

[0012] A support block is integrally provided on the outer wall of the second pair of joints, an arc-shaped piece is integrally provided on one side of the support block, and a second buckle is integrally provided at the end of the arc-shaped piece.

[0013] As a preferred solution of the cable connector docking and snap-fitting structure described in the utility model, a third buckle is integrally provided on the outer wall of the docking column, a second buckle groove is opened on the docking tube, and the width of the second buckle groove is greater than the width of the third buckle.

[0014] Compared with existing technologies:

[0015] 1. By providing a first clamping groove on the first docking portion, the width of the first clamping groove is greater than the width of the first buckle on the second docking portion. Therefore, after the first pair of connectors and the second pair of connectors are plugged in, a small rotation can be generated between the first pair of connectors and the second pair of connectors. Therefore, when one of the cables connected to the first pair of connectors and the second pair of connectors is rotated under force, the twisting degree between the first pair of connectors and the second pair of connectors can be effectively reduced, thereby achieving protection for the first pair of connectors and the second pair of connectors.

[0016] 2. The third buckle and the first buckle groove are respectively provided on the docking column and the docking tube. Therefore, after the first pair of connectors and the second pair of connectors are plugged in, the docking column and the docking tube are buckled together, further enhancing the docking stability between the first pair of connectors and the second pair of connectors.
