Description

Technical Field

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

[0002] With the continuous development of society and the electronics industry, connectors, also known domestically as plugs, sockets, and connectors, generally refer to electrical connectors. They are devices that connect two active devices, allowing current or signals to flow from one conductor to another. Simply put, electronic connectors are components used to complete electrical connections between circuits or electronic devices, thus becoming a bridge between them. Furthermore, because connectors come in a wide variety of forms and structures, depending on the application, frequency, power, and application environment, there are various types of connectors. The components that connect the circuit on all connectors are the contacts, or contact terminals. These contact terminals include power terminals, signal terminals, and ground terminals. Traditionally, all terminals are embedded (injection molding) or inserted into a single large insulating base in one piece. The position and spacing of the terminals are entirely determined by the structure of the insulating base and are indivisible.

[0003] Later, someone invented a connector with modular terminals. By pre-assembling terminals with corresponding functions into independent terminal modules, multiple terminal modules are stacked and assembled into a complete connector according to the use requirements of the connector. However, the connection and positioning structure design on the shell after stacking multiple terminal modules is not good. This makes it easy for some terminal modules to shift in position when subjected to external vibration or collision, resulting in a high rework rate and making it difficult to connect the connector to the equipment for subsequent soldering operations. This limits its applicability.

[0004] Therefore, it is necessary to research a new technical solution to address the above problems. Utility Model Content

[0026] Please refer to Figures 1 to 3 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0027] A modular terminal connector structure includes a housing 10, a terminal module 11, and a locking member 12; wherein:

There are two positioning posts 13, which are respectively arranged between the two support parts 14 on the corresponding sides. In this way, the positioning post is provided to facilitate the positioning and connection of the housing on the device. Together with the support part, it ensures that the connector will not shake during use, thereby improving the safety and stability of the connector.

[0033] Preferably, the opposite sides of the insertion cavity 101 are respectively provided with anti-mistake protrusions 106 and anti-mistake recesses 107. This facilitates the accurate and smooth insertion of the connector into the insertion cavity, avoids damage to the terminals due to incorrect insertion of the connector, and results in a long service life and good usability.

[0034] The key design feature of this utility model is that it achieves locking and positioning of the terminal module in the mounting cavity by matching the locking groove of the locking fastener with the locking part of the insulator through the design of each component. This ensures the accurate and firm connection of the terminal module to the outer shell, avoids the positional displacement of some terminal modules due to external influences, facilitates the subsequent welding operation of the terminal module with the equipment, improves the production efficiency of the product, and has strong practicality and wide applicability.

[0035] Secondly, the rotatable design of the connection part allows the locking parts to be opened by rotating on the housing, which facilitates the placement and maintenance of the terminal module in the mounting cavity, resulting in excellent usability. At the same time, the reinforcement part improves the welding reliability between the terminal and the equipment.

[0036] Furthermore, the positioning post facilitates the positioning and connection of the housing on the equipment.
