[0002] Ethernet refers to the most common communication protocol standard used in the existing local area networks. If electronic devices are to be connected to Ethernet and exchange data with Ethernet, using data cables is the most common and direct means of implementation. Connectors, as the intermediate components connecting electronic devices and data cables, have been produced and used on a large scale in daily life.
[0003] With the development of my country's automobile industry, consumers' requirements for automobile functions are gradually increasing. Now, waterproof function is also a key direction for automobile development. A car with good waterproof function means that it can adapt to more complex terrains and roads and has higher driving safety performance.
[0004] The utility model with Chinese patent authorization announcement number CN21745374223U discloses a waterproof automotive connector, which includes a shell, an outer conductor, an insulator and an inner conductor from the outside to the inside. The outer conductor is snapped into the shell, that is, the outer conductor can be stably configured in the shell. The outer circumference of the outer conductor is provided with at least one snap-in groove. Correspondingly, the inner wall of the shell is convexly provided with a snap-in protrusion, and the snap-in protrusion is configured in the snap-in groove. The snap-in protrusion is an elastic deformable structure, such as a spring structure, so that when the outer conductor is inserted into the accommodating cavity of the shell, the snap-in protrusion can be deformed so that it can be reliably snap-into the shell.
[0005] The clamping protrusion is an elastic and deformable structure, and when it is reversely squeezed by the outer conductor, it will deform outwards. The clamping stability between the clamping protrusion and the clamping groove opened on the outer circumference of the outer conductor needs to be improved. Utility Model Content

[0036] See also Figure 1-7 A vehicle-mounted Ethernet waterproof connector in the present application includes an electrical connection component 4, a bracket 5 and a housing 7, and a cable 1 is connected to the rear end of the electrical connection component 4.
[0037] In the present application, the electrical connection component 4 is composed of an outer conductor, an insulator and an inner conductor from the outside to the inside, and the inner conductor and the outer conductor are respectively electrically connected to the cable 1.
[0038] The bracket 5 is in the shape of a hollow tube, and a notch 51 is provided on the circumferential wall in the middle of the bracket 5. An elastic clamping protrusion 52 is provided in the notch. The elastic clamping protrusion 52 is in the shape of a strip and is arranged along the axial direction. The root of the elastic clamping protrusion 52 is connected to the rear side of the notch as a whole, and the front end of the elastic clamping protrusion 52 is a free end, and protrudes outwardly from the outer wall of the bracket 5 and inwardly from the inner wall of the bracket 5.
[0039] During the first assembly, the electrical connection component 4 is first inserted into the bracket 5, and the elastic snap-fit protrusion 52 is deformed outward. After the electrical connection component 4 passes smoothly, the elastic snap-fit protrusion 52 recovers its deformation and abuts against the electrical connection component 4 to prevent the electrical connection component 4 from retreating.
[0040] An axial limiting structure for limiting the penetration of the electrical connection component 4 into the limit position is provided in the housing 7, and the axial limiting structure can be a housing clamping step 71 protruding from the inner wall. The middle part of the electrical connection component 4 is protruded to form an outer conductor shoulder 41. When the electrical connection component 4 is previously penetrated into the housing 7, the front end of the outer conductor passes through the housing clamping step 71 until the outer conductor shoulder 41 abuts against the inner side of the housing clamping step 71, and the electrical connection component 4 cannot move forward any further.
[0041] When reassembling, the electrical connection component 4 and the bracket 5 are inserted into the shell 7 together, and the elastic snap-in protrusion 52 that holds the electrical connection component 4 interferes with the inner surface of the shell 7 and deforms inward, so that the elastic snap-in protrusion 52 maintains a holding force to squeeze the electrical connection component 4 forward, and the electrical connection component 4 is squeezed toward the elastic snap-in protrusion 52 through the axial limiting structure, so that the electrical connection component 4 is held between the shell 7 and the bracket 5.
[0042] In the present application, there are multiple elastic snap-fit protrusions 52, and the multiple elastic snap-fit protrusions 52 are evenly distributed around the circumference of the bracket 5. A snap-fit groove 42 cooperating with the elastic snap-fit protrusion 52 is provided on the outer wall of the electrical connection component 4, and the snap-fit groove 42 is arranged around the circumference of the electrical connection component 4, and the elastic snap-fit protrusion 52 abuts against the front side wall of the snap-fit groove 42.
[0043] In order to hold the bracket 5, a block 53 cooperating with the shell is provided on the outer side of the rear end of the bracket 5 in the insertion direction, and a slot 74 for fixing the bracket 5 is provided on the rear end of the shell 7 along the insertion direction of the bracket 5. The block 53 and the slot 74 are interlocked to prevent the bracket 5 from falling off from the inside and ensure that the electrical connection component 4 in the bracket 5 is in the correct position, thereby playing the role of holding and positioning.
[0044] In the present application, the rear portion of the housing 7 is provided with one or more card slots 74 for retaining the bracket 5, and the bracket 5 is correspondingly provided with a plurality of card blocks 53 that can slide into the card slots 74 along the insertion direction. At the end of the stroke when the electrical connection component 4 and the bracket 5 are inserted into the housing 7 together, the card block 53 is inserted into the card slot 74 to prevent the bracket 5 from retreating.
[0045] To improve the waterproof performance, a bracket sealing ring 6 is provided between the bracket 5 and the shell 7, a cable sealing ring 3 is provided between the bracket 5 and the cable 1, and a shell sealing ring 8 is fixed to the inner wall of the front end plug interface of the shell 7.
[0046] In order to prevent the cable sealing ring 3 from falling out, the rear end of the housing 7 is clamped with the rear cover 2, which abuts against the outside of the cable sealing ring to prevent the cable sealing ring from falling out. The clamping structure of the housing 7 and the rear cover 2 is as follows: the rear end of the housing 7 is a rear cover joint 73, and the outer circumference of the rear cover joint 73 is provided with a second clamping block 731, the rear cover 2 is rotated outside the rear cover joint 73, and the inner wall of the rear cover 2 is provided with a second clamping groove 21 clamped with the above-mentioned second clamping block.
[0047] When assembling the cable 1, the front end of the cable 1 first passes through the rear cover 2, then passes through the cable sealing ring 3, and is riveted to the inner and outer conductors of the electrical connection component 4. The electrical connection component 4 is then passed through the bracket 5 to seal the bracket 5 and the cable 1. The electrical connection component 4 and the bracket 5 are then passed through the outer shell 7 together until an end point is formed. The electrical connection component 4 is held between the outer shell 7 and the bracket 5. Finally, the rear cover 2 is clamped to the tail of the outer shell 7.
[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
