Description

Technical Field

[0001] The utility model relates to the technical field of connector terminal structures, and more specifically to a connector plug-in terminal structure. Background Art

[0002] Connectors are also called connectors. In China, they are also called joints and sockets. They generally refer to electrical connectors. They are devices that connect two active devices and transmit current or signals. The male and female ends can transmit information or current after contact, and are also called connectors.

[0003] At present, the plug-in terminal structure of the connector on the market requires crimping terminals. Usually, a single crimping terminal is connected to a cable, and then the crimped terminal is connected to the connector. When two or more cables need to be connected in parallel at an interface on the connector, multiple terminals need to be stacked at the interface of the terminal row. After stacking, they are fixed with bolts to limit the height of the cover above the terminal row.

[0004] Since each cable needs to be crimped with a terminal head, it is very time-consuming and laborious, and many unmounted terminal heads need to be prepared in advance to ensure that there are enough crimps. Since the terminal head is directly locked and fixed by a single bolt, although this is a convenient installation method, the terminal head will rotate based on the bolt, and the terminal head cannot be limited and locked, which may cause the terminal head to fall off or short-circuit. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a terminal structure for connector plugging.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A terminal structure for connector plugging, comprising a terminal head mechanism, a wire fixing mechanism installed at the front end of the terminal head mechanism, a limit mechanism installed at the front end of the wire fixing mechanism, a connecting mechanism connected and fixed to the limit mechanism, and a clamping mechanism installed at the front end of the connecting mechanism;

[0008] A support plate is installed at the top of the bottom plate, and the support plate is connected to the wire fixing mechanism, and the wire fixing mechanism includes a second pressing plate, and the second pressing plate is arranged between the limiting mechanism and the terminal head mechanism;

[0009] The limiting mechanism comprises a limiting plate, the limiting plate is connected to the connecting mechanism, and the connecting mechanism is fixedly connected to the clamping mechanism.

[0010] The utility model is further configured as follows: the terminal head mechanism includes a bottom plate, wire holes are opened at both ends of the bottom plate, a folding groove is opened in the middle of the bottom end of the bottom plate, and the front of the bottom plate is connected to the support plate.

[0011] By adopting the above technical solution, the terminal head of the crimping terminal can connect two cables. When the crimped terminal is connected to the connector and two cables need to be connected in parallel at one interface on the connector, there is no need to stack multiple terminals at the interface of the terminal row. The bottom plate can be folded through the folding groove and used to connect two cables.

[0012] The utility model is further configured as follows: the line fixing mechanism also includes a first pressing plate, the rear end of the first pressing plate is fixedly connected to the support plate, a first clamping block is installed on the upper end of the first pressing plate, a second pressing plate is installed on the front end of the first pressing plate, and a second clamping block is installed on the upper end of the second pressing plate.

[0013] The utility model is further configured as follows: the opening outer diameter spacing of the second pressing plate is 2.22 mm, the side length of the second clamping block is 0.5 mm, and the bottom edge circle diameter of the second pressing plate is 0.76 mm.

[0014] The utility model is further configured as follows: the limiting mechanism further comprises a limiting convex point, the limiting convex point is installed in the middle position of the limiting plate, and folding plates are installed on both sides of the limiting plate.

[0015] The utility model is further configured as follows: the connection mechanism comprises two connection plates symmetrically mounted on the front end of the limit plate, and a limit groove is arranged between the two connection plates.

[0016] The utility model is further configured as follows: an adjusting plate is installed at the front end of the connecting plate, a clamping plate is installed at the lower end of the adjusting plate, an upper plate is installed at the upper end of the adjusting plate, and a hook is installed at the front end of the upper plate.

[0017] By adopting the above technical solution, the cable can be better pressed by designing the length of the second pressure plate, and the angle of the first clamping block can clamp the cable tightly on the terminal. When the cable passes through the clamping mechanism, the adjustment plate can be adjusted to a suitable angle to press the buckle to the clamping plate position.

[0018] In summary, the present application includes at least one of the following beneficial technical effects:

[0019] 1. A foldable bottom plate is provided, which can be folded and inserted into the connector, avoiding the problem of fixing multiple terminals with bolts when they are installed on the connector, thus limiting the height of the cover plate above the terminal row.

[0020] 2 When the cable passes through the limiting mechanism, the cable will be fixed in the limiting protrusion. When the cable reaches the clamping mechanism, it will be fixed on the clamping plate by the hook, avoiding the problem of the cable falling off when it is installed on the connector.
