Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of connectors, and particularly relates to a structure with a snap ring observation hole added at the wire end. Background Art
[0002] The MINI FAKRA wire end connector is mainly used in the field of automotive electronics. With the continuous progress of automotive electronics technology and the continuous popularization of intelligent vehicles, the market demand is increasing continuously, and the industry shows a rapid growth trend. This growth trend is mainly due to the rapid increase in the penetration rate of the ADAS intelligent driving assistance system and the increase in the usage of in-vehicle sensors, resulting in a relatively higher demand for high-speed, high-frequency, and large-data-volume transmission, which in turn promotes the growth in the usage of in-vehicle radio frequency connectors. To meet this market demand, the technical development trends of FAKRA connectors include the improvement of the frequency domain, miniaturization, ultra-low loss, waterproof and shock-resistant, etc., to meet the high requirements for the quality and reliability of connectors in the field of automotive electronics; in terms of market competition, due to the continuous development and popularization of connector manufacturing technology, the competition in the MiniFAKRA connector market is becoming increasingly fierce. Each connector manufacturer continuously launches more competitive products to compete for market share. This competition is not only reflected in the improvement of product performance but also includes the optimization of cost and delivery cycle to adapt to the rapidly changing market demand.
[0003] However, the traditional MINI FAKRA wire end connector cannot meet people's needs, and it has the following defects: First, there is no observation device designed. For the cable used in the MINI FAKRA connector, the snap ring is completely inside the rear shield during production, and it is impossible to judge whether the snap point of the rear shield catches the snap ring. The snap ring is an important component providing tension. If the snap ring is not caught on the snap point of the rear shield, the cable will be pulled off, causing serious accidents; Second, there is no simple device body designed. The MINI FAKRA connector is the next-generation miniaturized product of the FAKRA connector. Compared with the traditional FAKRA product, this interface supports data transmission of up to 20 Gbps and can reduce the installation space by 80%. A simpler structure is needed to facilitate the installation of the connector in the vehicle. An overly complex structure will result in a larger occupied space, which is not reasonable for in-vehicle use. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a structure with a snap ring observation hole added at the wire end to solve the problems put forward in the above background art.
[0005] To solve the above technical problems, the present utility model provides the following technical solutions: A structure with a snap ring observation hole added at the wire end, comprising a connector assembly.

A rear shielding shell is sleeved on the outer wall of one side of the cable. An observation hole body is provided on the outer wall of one side of the rear shielding shell, and the observation hole body is arranged on the upper surface of the snap ring body.
[0006] As a further technical solution of the present utility model, a metal tape is fixedly connected to the outer wall of one side of the cable.

The situation can be observed at the first time when the cable is pulled off, and serious accidents caused by failure to detect the detachment of the clamping ring body can be avoided; at the same time, a simple structural body is designed. For the device used, the components are simplified on the basis of the original connector.

A rubber core 2 is sleeved on the outer wall of the other side of the rear-end shielding assembly 3. A front-end shielding assembly 1 is sleeved on one end of the rubber core 2. The connector assembly 4 includes a cable 43. A snap ring body 42 is fixedly connected to the outer wall of one side of the cable 43. A rear shielding shell 32 is sleeved on the outer wall of one side of the cable 43. An observation hole body 31 is formed on the outer wall of one side of the rear shielding shell 32, and the observation hole body 31 is arranged on the upper surface of the snap ring body 42; A metal tape 44 is fixedly connected to the outer wall of one side of the cable 43. An insulator 45 is fixedly connected to the outer wall of one side of the metal tape 44. A second inner conductor 46 is fixedly connected to the outer wall of one side of the insulator 45. The insulator 45 is used to prevent the current from flowing to the surface of the device; A braided shield 47 is fixedly connected to the outer wall of one side of the cable 43, and the braided shield 47 is sleeved on the outer wall of one side of the snap ring body 42. A sheath 48 is fixedly connected to the outer wall of one side of the braided shield 47. The sheath 48 is used to protect the cable 43; A protective layer 23 is sleeved on the outer wall of one side of the rear shielding shell 32. An insulating layer 22 is sleeved on the outer wall of one side of the protective layer 23. The protective layer 23 is located on the outermost layer of the rubber core 2. Its main function is to protect the insulating layer 22, prevent it from being damaged during transportation, laying and use, and at the same time prevent moisture from invading. The insulating layer 22 is wrapped outside the first inner conductor 21, playing the role of electrical insulation, preventing the current from flowing to the outside, ensuring that the transmitted current or electromagnetic wave only travels along the conductor, and at the same time ensuring a certain electrical withstand voltage strength, having heat resistance performance and stable insulation quality; A front shielding shell 11 is sleeved on the outer wall of one side of the protective layer 23. A cap 12 is fixedly connected to one end of the front shielding shell 11. The front shielding shell 11 is used to protect the rubber core 2; A first inner conductor 21 is fixedly connected to the outer wall of one side of the insulating layer 22, and the first inner conductor 21 is sleeved on the output end of the terminal 41. The terminal 41 is used to connect the first inner conductor 21 and the second inner conductor 46 to transmit electrical signals; A connecting piece 13 is fixedly connected to the outer wall of one side of the cap 12. The connecting piece 13 is used to connect the cap 12 and the front shielding shell 11.
[0020] Working principle: When using this utility model, first assemble the device. Fix the second inner conductor 46 inside the insulator 45. The insulator 45 prevents the current from flowing to the surface of the device. Fix the insulator 45 inside the metal tape 44 to form a complete cable 43. Install the cable 43 in the rear shielding component 3 through the rear shielding shell 32, and protect the snap ring body 42 on the cable 43 through the braided shield 47. Connect with the terminal 41 on the connector component 4 and the rubber core 2. The rubber core 2 is composed of a first inner conductor 21, an insulating layer 22, and a protective layer 23. The first inner conductor 21 is the core part of the rubber core 2, responsible for transmitting electricity or signals. It can be made of metals with excellent electrical conductivity such as copper or aluminum, or an optical fiber used in an optical communication network. The insulating layer 22 is wrapped outside the first inner conductor 21, playing the role of electrical insulation, preventing the current from flowing to the outside, ensuring that the transmitted current or electromagnetic wave only travels along the conductor, and at the same time ensuring a certain electrical withstand voltage strength, having heat resistance performance and stable insulation quality. The insulating materials mainly include polymer materials such as plastics and rubbers. The protective layer 23 is located on the outermost layer of the rubber core 2, mainly to protect the insulating layer 22, prevent it from being damaged during transportation, laying, and use, and at the same time prevent moisture from invading. Install the rubber core 2 in the front shielding component 1 through the front shielding shell 11 to protect the whole rubber core 2, and install the cap 12 on the front shielding shell 11 through the connecting piece 13; after using this connector to complete the on-vehicle circuit connection, the state of the snap ring body 42 can be observed through the observation hole body 31 on the rear shielding component 3, effectively judging whether the clamping point of the rear shielding shell 32 has clamped the snap ring body 42. Since the snap ring body 42 is an important component providing tension, it can effectively avoid the situation where the snap ring body 42 is not clamped on the clamping point of the rear shielding shell 32 and cannot be detected, and the situation can be observed immediately when the cable 43 is pulled off, avoiding the occurrence of serious accidents caused by not detecting the detachment of the snap ring body 42. Among them, the sheath 48 is used to protect the cable 43.
