Description
Technical Field
[0001] This utility model relates to the field of connectors, and in particular to a right-angle cable exit connection assembly with secondary locking. Background Technology
[0002] Electrical connectors are indispensable components in electronic and electrical devices. For electrical connectors, the ability to make stable and reliable, high-speed transmission of signals or current is essential. Connector assemblies typically include mating plug connectors and socket connectors. Traditional plug and socket connectors are usually connected and fixed by the tight fit of conductive springs or housings during insertion. However, this type of locking force is insufficient, especially in harsh application environments, which can easily lead to poor electrical contact. In particular, under high voltage conditions, a larger locking force is required to prevent the plug and socket connectors from loosening and causing poor electrical contact.
[0003] Therefore, existing connectors are generally equipped with locking structures, such as snap-fit or latch, to connect two connectors and improve the connection stability between the two connectors. However, the locking structure is generally a one-time locking mechanism and does not lock and fix the locking structure again, thus failing to further improve the locking stability.
[0004] In addition, the direction of the connector's outgoing wires or lead wires is also crucial, as it corresponds to the overall arrangement capacity of multiple connectors. Therefore, the ease of operation when connecting or disconnecting the connectors must also be considered. Utility Model Content

The pressing block is disposed on the opposite side of the elastic arm based on the insertion and removal direction. In the locked state, the second limiting block engages with the first limiting block, and the second locking block engages with the second locking groove. In the unlocked state, the second limiting block separates from the first limiting block, and the second locking block separates from the second locking groove.
[0007] A further proposed solution is to install a fixing flange on the outer wall of the fixed housing, with the fixing flange perpendicular to the insertion / removal direction and located between the fixing lead end and the hinge post.
[0008] A further proposed solution is to provide a positioning flange on the outer wall of the fixed housing, which extends circumferentially and is located between the hinge post and the fixed connection end. When the fixed end connector and the free end connector are connected, the end of the fixed housing is inserted into the free housing, and the end of the free housing is adjacent to the positioning flange.
[0009] A further proposed solution is to have an extension block between the two first locking blocks on the outer wall of the free end connector, forming a second locking groove between the extension block and the outer wall of the free end connector.
[0010] A further embodiment is that the lock cover has a second sliding groove between its inner sidewalls, the second sliding groove extends along the insertion / removal direction, the first sliding groove communicates with the second sliding groove and has an opening at the end near the free end connector; the sliding lock block includes a second slider, the fixed end of the second slider is connected to the pressing block, the second slider moves in the second sliding groove along the insertion / removal direction, the pressing block covers the opening, and the elastic arm can elastically deflect toward the second sliding groove.

Subsequently, by pushing the sliding locking block in again, and utilizing the elastic deformation of the first slider, the second limiting block engages with the first limiting block, and the second locking block engages with the second slot. This not only fixes the locking position of the sliding locking block but also locks the free end connector again, thereby achieving a secondary locking of the connector. Attached Figure Description

The first locking block 25 is used to engage with the slot 51 to achieve a first locking. The outer wall of the free end connector 2 is provided with a locking block 27 between the two first locking blocks 25. The bayonet 52 is used to engage with the locking block 27 to achieve a second locking.
[0035] As can be seen from the above, since the fixed housing and the free housing are coaxially connected or separated along the insertion and removal direction, and both the fixed housing and the free housing are arranged at right angles along the insertion and removal direction, radial or circumferential space is saved, allowing for the arrangement of more connectors. Furthermore, the fixed flange facilitates the installation of the fixed end connector on a fixed object, and the annular arrangement of the positioning flange ensures that the end of the free housing is adjacent to the positioning flange, thereby improving connection stability. Moreover, the locking cover is connected to the fixed housing and the free housing, and the first slot can be detachably engaged with the first locking block to achieve the first locking, which provides the main locking force. Subsequently, by pushing the sliding locking block in again, and utilizing the elastic deformation of the first slider, the second limiting block engages with the first limiting block, and the second locking block engages with the second slot. This not only fixes the locking position of the sliding locking block but also locks the free end connector again, thereby achieving a secondary locking of the connector.
