Description

Technical Field

[0001] This utility model relates to the field of cable connectors, and more particularly to an M17 elbow cable connector. Background Technology

[0002] Cable connectors are mainly used for signal transmission between transmission devices. They are commonly used in devices that transmit data, audio, and video by connecting devices and cables.

[0003] Currently, the M17 series cable connectors on the market only have unidirectional straight-out output. When connecting at corners or where the cable needs to rotate, the cable bending angle will be too large. In addition to easily causing improper compression of the wire core inside the cable, it is also difficult to insert and remove the cable smoothly in the limited space. In order to overcome such problems, the inventor of this utility model has proposed an improvement strategy to overcome the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an M17 elbow cable connector, which is designed for elbow applications and can be used in places where the cable connection angle or direction needs to be changed, including:

[0032] like Figure 1 As shown, the M17 elbow cable connector of this utility model includes a first shell group 10, a second shell group 20, and a wire connection assembly 30. The first shell group 10 and the second shell group 20 are connected to form a bend, and an included angle θ is formed between the first shell group 10 and the second shell group 20. This included angle can be from 10 degrees to 170 degrees, that is, the included angle between the first shell group 10 and the second shell group 20 can be arbitrarily set according to the requirements. Preferably, in this embodiment, the included angle between the first shell group 10 and the second shell group 20 is 90 degrees. The wire connection assembly 30 is disposed between the first shell group 10 and the second shell group 20.

[0033] The first housing assembly 10 includes a connecting housing 11, a locking nut 12, a stop ring 13, and a sealing ring 14. The connecting housing 11 is a hollow housing with two ends, namely a connecting end 110 and a cable outlet end 111. A semi-arc plate is protruding from the connecting end 110, and the bottom of the plate is an inclined connecting arc surface for connecting with the second housing assembly 20. The cable outlet end 111 is on the opposite side of the connecting end 110, in the direction in which the cable extends outward. A foolproof groove 112 is provided on the inner side of the connecting housing 11 for assembling with the wire connection assembly 30 and preventing slippage. A sealing groove 113 is provided on the inner side of the connecting housing 11 for installing the sealing ring 14. A stop groove 114 is provided on the outer side of the cable outlet end 111 of the connecting housing 11 for installing the stop ring 13.

[0034] The locking nut 12 is disposed at the outlet end 111 of the connecting shell 11, the stop ring 13 is disposed between the locking nut 12 and the connecting shell 11, and is correspondingly disposed in the stop groove 114, and the sealing ring 14 is installed in the sealing groove 113 to prevent liquid from flowing in.

[0035] The second housing assembly 20 includes a serial housing 21, a sealing ring 22, a tail clip housing 23, a wire buckle 24, a wire clamp 25, a locking nut 26, and a positioning bolt 27. The serial housing 21 also has two ends, namely a connecting end 210 and a wire inlet end 211. The opening direction of the connecting end 210 is consistent with the connecting end 110 of the connecting housing 11, and it is used to connect with the connecting housing 11. The wire inlet end 211 is located on the opposite side of the connecting end 210 and is used to thread the cable through it. A recessed connecting groove 212 is formed on the upper outer side of the connecting end 210 of the serial housing 21. The connecting groove 212 matches the connecting end 110 of the connecting housing 11, so that the connecting end 110 can be correspondingly inserted into the connecting groove 212. A sealing groove is provided on the outer side of the wire inlet end 211 of the serial housing 21 for connecting the sealing ring 22.

[0036] The sealing ring 22 is correspondingly disposed in the sealing groove, and the tail clip shell 23 is correspondingly connected to the inner side of the inlet end 211 of the serial shell and abuts against the bottom of the sealing ring 22; the wire buckle 24 and the wire clamp 25 are sequentially disposed in the tail clip shell 23, and the locking nut 26 covers the wire buckle 24 and the wire clamp 25 and is correspondingly screwed into the bottom of the tail clip shell 23 so that the wire buckle 24 and the wire clamp 25 will not fall outward.

[0037] The wire connection assembly 30 is used to connect cables and includes a terminal block 31, an insulating core 32, and a grounding plate 33. The terminal block 31 is used to connect the wire harness on the cable. After connecting the wire harness, the insulating core 32 covers the outside of the terminal block 31 and the wire harness. In this embodiment, the insulating core 32 is composed of three detachable rubber sheets 321. A protrusion 322 corresponding to the slot 112 of the connecting shell 11 is provided on the outside of the insulating core 32 so that when the insulating core 32 is fixed in the connecting shell 11, it is not easy to fall off with the movement of the cable. The grounding plate 33 is connected to the terminal block 31 and is used for grounding and improving shielding.

[0038] The assembly method of this utility model is as follows: Remove the outer sheath of the cable end to be processed according to the part size, fold the shield back, and clean off any excess filler. Insert the cable into the inlet end 211 of the serial housing 21 and pull it out from the joint end 210. Wrap the front end of the cable with PE film to prevent loss of parts. Then, according to the size of the terminal 31, peel off the outer sheath of the cable, expose the wire harness, connect it to the terminal 31, and crimp it. Assemble the insulating core 32 onto the outside of the crimped terminal 31, and simultaneously assemble the grounding piece 33 onto... The grounding PIN corresponding to the terminal 31 is then connected to the cable of the wire connection assembly 30 and installed into the connecting shell 11 of the first shell assembly 10. The insulation is then engaged with the insulating core 32 in the connecting shell 11, and one end of the cable extends out from the outlet end 111. The cable outlet end is then fixed with the locking nut 12, and the connecting shell 11 and the serial shell 21 are fixed with the positioning bolt 27. Finally, the cable inlet end is fixed with the wire clamp 25, the wire buckle 24 and the locking nut 26 to complete the overall assembly.
