Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a connector with a connection structure. Background Technology

[0002] With the trend of integration and miniaturization in electronic devices, connectors, as core components for signal and power transmission, are facing increasingly complex and diverse application scenarios. Different devices and their internal modules have significantly different requirements for connector installation methods, arrangement, and space occupation. For example, in fields such as precision electronic instruments, automated control equipment, and new energy devices, connectors are needed for individual independent installation to meet simple local connection needs, while multiple connectors are often combined to form double-row or multi-row structures to adapt to high-density integrated transmission requirements. However, the existing connector structures are mostly fixed and single-form, and their shells do not have flexible splicing and combination functions, resulting in many limitations in practical applications. On the one hand, to adapt to different installation requirements such as single, double-row, and multi-row, it is necessary to design and produce a variety of different specifications and models of connectors, increasing the cost of research and development and manufacturing. It is also necessary to establish separate warehousing and management systems for different models of connectors, which also increases the later maintenance costs. On the other hand, there is a lack of standardized quick-connection structures between existing connectors. When multiple connectors need to be used in combination, additional fixing brackets, fasteners, and other auxiliary components are usually required for assembly and fixation, which increases costs. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a connector with a connection structure that is lower in cost and more flexible in use.

[0004] To achieve the above objectives, this utility model provides a connector with a connecting structure, including a housing, terminals, and limiting members. The housing includes an inner cavity for terminal installation. The housing includes a plurality of first connecting parts and a plurality of second connecting parts. The plurality of first connecting parts and second connecting parts are arranged in pairs on each end face of the housing circumferentially. The first connecting parts and second connecting parts arranged on the same end face are respectively located on both sides of the end face. The positions of the first connecting parts and second connecting parts on opposite end faces on both sides of the housing are opposite. The first connecting parts and second connecting parts can be inserted and limited to each other with the second connecting parts and first connecting parts of adjacent housings, respectively.

[0005] The advantages of the above technical solution are: by symmetrically pairing the first connecting part and the second connecting part on each end face of the shell, and making the positions of the first and second connecting parts on opposite end faces of the shell opposite, the precise insertion and limiting fit of the first connecting part and the second connecting part between adjacent connector shells can be achieved. Single, double or multiple rows can be quickly and flexibly combined without additional auxiliary fixing parts, adapting to the installation requirements of different scenarios, greatly simplifying the assembly process, improving the overlapping efficiency, and effectively avoiding installation direction deviation when multiple connectors are combined, ensuring connection positioning accuracy and signal transmission stability, and saving internal installation space of the equipment.

[0006] The present invention can be further configured such that: the first connecting part is provided in the shape of a protruding column, and the second connecting part is provided in the shape of a groove into which the first connecting part can be inserted.

[0007] By further designing the first connecting part into a convex column shape and the second connecting part into a matching groove shape, and adopting a plug-in mating structure between the convex column and the groove, not only can the connection between adjacent connector housings be realized, but the splicing operation steps are also simplified. No additional auxiliary fixing parts are needed, thus improving assembly efficiency. At the same time, the structural design of the convex column and the groove is compact and will not take up too much additional installation space.

[0008] The present invention can be further configured such that the first connecting part and the second connecting part are both located near the middle of the shell, and the extending direction of the first connecting part and the slot direction of the second connecting part are opposite to each other.

[0009] By further configuring the first and second connecting parts to be located near the center of the housing, and setting the extension direction of the first connecting part opposite to the slot direction of the second connecting part, the stress point of adjacent connectors during splicing is concentrated in the central area of ​​the housing, avoiding warping and loosening caused by uneven stress at the ends after splicing. At the same time, the opposite extension direction and slot direction ensure that the retraction directions of the two sets of first and second connecting parts are opposite, thereby achieving a limiting effect and ensuring the stability of the product.

[0010] The present invention can be further configured such that: an installation port for inserting a limiting member is provided in the middle of the shell, and the limiting member can be inserted into the inner cavity through the installation port and form a limiting engagement with the terminal.

[0011] By further designing the housing, an installation port is provided in the middle of the housing for inserting the limiting component. This allows the limiting component to extend into the inner cavity through the installation port and form a limiting engagement with the terminal. The limiting component positions the terminal. The engagement between the installation port and the limiting component does not require additional fixing structures on the housing, thus reducing product costs.

[0012] The present invention can be further configured such that: the limiting member includes a rod and a handle, the rod is used to extend into the inner cavity and abut against the terminal for limiting, the handle is located at the rear end of the rod and abuts against the wall of the housing mounting opening for limiting, and the handle is provided with a groove and a through hole on both sides respectively, the groove is for inserting the first connecting part, and the through hole is aligned with the slot of the second connecting part.

[0013] With further design, the handle abuts against the side wall of the housing mounting opening and is limited. At the same time, the two sides of the handle are respectively provided with grooves that are adapted to the first connecting part and through holes that are aligned with the groove of the second connecting part. This allows the limiting part to be reinforced through the cooperation between the first connecting part and the second connecting part. Furthermore, the grooves and through holes also serve to prevent errors.

[0014] The present invention can be further configured such that: the terminal is provided with a protrusion, and the housing includes an anti-misalignment groove provided at the position of the protrusion.

[0015] By further configuring the terminals with raised sections and anti-misalignment grooves at corresponding positions on the housing, the installation direction can be quickly identified during the terminal installation stage, effectively preventing reverse assembly of the terminals.
