Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a reliable double-row terminal connector. Background Technology

[0002] Existing connectors, due to their complex structural design, make insertion and removal cumbersome and laborious when installing male and female modules. Furthermore, they suffer from poor terminal fixation, leading to terminals detaching from the terminal holes. This is particularly true for dual-row terminal connectors, where the large number of terminals makes insertion and removal difficult. Therefore, the inventor aims to provide a connector with a simple and compact structure that is easy to insert and remove, and highly reliable. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the main purpose of this utility model is to provide a double-row terminal connector that is easy to plug in and unplug, has a stable and reliable structure.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a reliable double-row terminal connector, comprising a male terminal module and a female terminal module. The male terminal module includes a male terminal housing and a double row of male terminals fixedly disposed within the male terminal housing. The female terminal module includes a female terminal housing and a double row of female terminals fixedly disposed within the female terminal housing. A spring is provided in the middle of the female terminal housing. The spring is provided with a pressing part and two wedge-shaped locking parts. The female terminal housing has a relief groove below the spring for the spring to be pressed down. The male terminal housing has a relief groove for the spring to be pressed down. The inserted locking groove is provided with two abutting parts that can abut against the wedge-shaped locking parts and a limiting stop bar provided between the two abutting parts. The limiting stop bar is inserted in the middle of the two wedge-shaped locking parts. The female end plastic shell is provided with L-shaped protective blocks extending into the clearance groove on both sides of the spring piece. The L-shaped protective blocks abut against the male end plastic shell. The male end plastic shell and the female end plastic shell are respectively provided with terminal holes for inserting male terminals and female terminals. The male terminal and the female terminal are respectively provided with terminal barbs on both sides that can make tight contact with the inner wall of the terminal hole.

[0005] Preferably, the female end plastic shell is provided with guide limiting parts on both sides of the spring sheet, and the male end plastic shell is provided with guide limiting grooves that cooperate with the guide limiting parts.

[0007] Preferably, the male end plastic shell and the female end plastic shell are respectively provided with side ear grooves for inserting the male end side ear and the female end side ear, and the two sides of the male end side ear and the female end side ear are respectively provided with side ear barb structures that can closely contact the inner wall of the side ear groove.

[0008] This invention has the following advantages over existing technologies: its single locking structure, formed by the cooperation of a spring and a locking groove, facilitates insertion and removal while ensuring reliability. The spring is equipped with a pressing part and two wedge-shaped locking parts. The female end plastic shell has a relief groove below the spring for pressing down on it. During installation, when the female end plastic shell is inserted into the male end plastic shell, pressing down on the pressing part pushes the spring down, facilitating its entry into the locking groove. Releasing the pressing part causes the two wedge-shaped locking parts on the spring to abut against the two abutment parts in the locking groove, thus locking the male and female end modules together. During disassembly, simply pressing down on the pressing part allows the spring to disengage from the locking groove, separating the male and female end modules. The guide limiting part and guide limiting groove enhance the accuracy and connection stability when the male and female end modules are connected. The connector features two wedge-shaped locking sections that widen the spring clip, increasing the locking area and improving reliability. A stop bar, inserted between the two wedge-shaped locking sections, limits and secures the spring clip, ensuring connection accuracy and reliability. The female housing has L-shaped protective blocks extending into the clearance groove on both sides of the spring clip. These blocks prevent accidental activation of the pressing part, preventing accidental unlocking of the connector. Both the male and female housings have terminal holes for inserting male and female terminals. Each terminal has barbs on both sides that ensure tight contact with the inner wall of the terminal hole. The male and female terminals are installed under pressure and secured in place by the barbs, ensuring a secure connection and improving reliability. Attached Figure Description
