Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to the outer conductor structure of a waterproof elbow connector. Background Technology

[0002] With societal development, the application of waterproof elbow connectors is becoming increasingly widespread. While the existing outer conductor structure of waterproof elbow connectors can meet basic functional requirements to a certain extent, it still has shortcomings: The existing outer conductor structure cannot completely prevent the intrusion of external interference signals and the leakage of internal signals. In some complex electromagnetic environments, external interference signals may enter the connector through the shielding gaps or weak points of the outer conductor, interfering with normal signal transmission and causing signal distortion, increased bit error rate, and other problems. Simultaneously, internal signals may also leak out, interfering with other surrounding electronic equipment and affecting the EMC (electromagnetic compatibility) performance of the entire system. Furthermore, when the male or female terminals of the connector are mated, a significant force needs to be applied between the contact surfaces of the male or female outer conductors to ensure the continuity of the electrical and mechanical structure. This means that the existing outer conductor structure is prone to deformation and wear during long-term, frequent mating processes due to the large insertion force and contact pressure, thus affecting the connector's performance and lifespan.

[0017] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front", "back", "horizontal", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] It should be noted that the terms "horizontal" and "vertical" in this utility model are used to describe approximate positional relationships, and not strictly "horizontal plane" or "vertical plane".

[0020] like Figure 1 As shown, a preferred embodiment of the waterproof elbow connector has an outer conductor structure, including an outer conductor body 1 and a spring sheet assembly. The outer wall of the outer conductor body 1 is provided with a plurality of mounting groove modules, which are evenly arranged along the circumference of the outer conductor body 1. Each mounting groove module is provided with a spring sheet assembly.

[0021] Furthermore, as a preferred embodiment, the mounting slot module includes: a first slot 2 and a second slot 3, the first slot 2 is disposed on one side of the second slot 3, the first slot 2 and the second slot 3 are connected, and the first slot 2 and the second slot 3 are offset along the axial direction of the outer conductor.

[0022] Furthermore, as a preferred embodiment, the spring assembly includes a first spring 4 and a second spring 5, wherein the first spring 4 is disposed within a first slot 2 and the second spring 5 is disposed within a second slot 3. Furthermore, by providing the first spring 4 and the second spring 5, the problem of contact failure after wear of a single spring can be avoided. The first spring 4 and the second spring 5 can form a double-spring stepped structure, thereby creating redundant contact. Even if one spring wears out, the other spring can still maintain a conductive or mechanical connection with the connector.

[0023] Furthermore, as a preferred embodiment, the first spring 4 and the second spring 5 located in the same mounting slot module form a certain angle.

[0024] Furthermore, as a preferred embodiment, the horizontal dimension of the first spring 4 is different from the horizontal dimension of the second spring 5, and this arrangement can be applied to annular contact structures.

[0025] Furthermore, in a preferred embodiment, one end of the first spring 4 is connected to the sidewall of the first slot 2, and the other end of the first spring 4 is arc-shaped. Furthermore, the arc shape allows the first spring 4 to buffer and disperse stress through its own elastic deformation when subjected to external force. When the male or female connector terminals mate, the arc-shaped end of the first spring 4 contacts the corresponding female or male terminal component, dispersing the insertion force through the elastic deformation of the arc surface, thereby preventing the outer conductor body 1 from deforming due to stress concentration.

[0026] Furthermore, in a preferred embodiment, one end of the second spring piece 5 is connected to the side wall of the second slot 3, and the other end of the second spring piece 5 is arc-shaped.

[0027] Furthermore, in a preferred embodiment, both the first spring 4 and the second spring 5 are made of conductive materials. More specifically, both the first spring 4 and the second spring 5 are made of conductive materials such as beryllium bronze or phosphor bronze.

[0028] Furthermore, in a preferred embodiment, the net distance between the first spring 4 and the axis of the outer conductor body 1, and the net distance between the second spring 5 and the axis of the outer conductor body 1, located in the same mounting slot module, are different.

[0029] Furthermore, in a preferred embodiment, the two first spring contacts 4 in two adjacent mounting slot modules are distributed at 90° to each other, and the two second spring contacts 5 in two adjacent mounting slot modules are also distributed at 90° to each other. Furthermore, when the connector is subjected to external forces from various directions, the first spring contacts 4 and second spring contacts 5, evenly distributed along the circumference, can not only disperse stress from multiple directions, thus ensuring the structural integrity of the outer conductor body 1, but also comprehensively block and attenuate electromagnetic interference signals from different directions, thereby effectively improving the EMC shielding performance of the connector.

[0030] The working principle of this utility model is as follows: During the mating process of the male or female end of the connector, the components of the male or female end contact the spring sheet group on the outer conductor body 1. The first spring sheet 4 and the second spring sheet 5 buffer and disperse the insertion force through their own elastic deformation. Due to the differences in the included angle, size, and net distance between the first spring sheet 4 and the second spring sheet 5 and the axis of the outer conductor body 1, stress can be effectively dispersed from multiple angles and directions, preventing the outer conductor body 1 from deforming due to excessive insertion force, thereby ensuring the continuity of electrical and mechanical structures. During signal transmission, when there are external electromagnetic interference signals, these interference signals will be reflected, absorbed, or attenuated when they encounter the first spring sheet 4 and the second spring sheet 5. Multiple first spring sheets 4 and second spring sheets 5 work together in different directions to block interference signals from entering the connector in all directions, protecting the internal signals from interference. At the same time, for the signals transmitted inside the connector, the first spring sheet 4 and the second spring sheet 5 can also effectively limit their leakage to the outside, avoiding electromagnetic interference to surrounding equipment, thereby achieving a good electromagnetic shielding effect and meeting the high requirements for shielding performance in specific application scenarios.

[0031] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
