Description

Technical Field

[0001] The utility model belongs to the technical field of cable laying equipment, in particular to a novel CPA structure. Background Art

[0002] In electronic devices, connectors play a key role in transmitting signals and power. In order to ensure that connectors can reliably perform their functions, various designs and technical means are needed to ensure the fixity of their positions and the stability of terminal connections. Connector Position Assurance (CPA) is an important performance to ensure connector reliability.

[0003] The industrial hybrid connectors currently on the market are mainly quick-lock products. Quick-lock products are easy and quick to install, which can improve the installation efficiency of end users and facilitate wiring. However, there will definitely be gaps due to the quick-lock structure. In addition, the hybrid product is larger in size, and the plug and socket are fastened to the hook in the middle of the socket by the locking rod. There is still shaking when pulling the wire. The vibration resistance is not as good as the screw locking structure. There is a risk of the locking rod being unhooked during vibration, causing downtime. In addition, the area of ​​the hand-pressed position of the locking rod of the existing product is small, and it is a sharp metal surface, which is easy to get injured during operation and is not conducive to installation. Utility Model Content

[0004] The purpose of the utility model is to provide a novel CPA structure in order to solve the above problems.

[0005] The technical solution adopted by the utility model is as follows: a new CPA structure, comprising:

[0008] CPA, whose buckle is connected to the outer wall of the upper end of the lock rod. The left and right sides of the lower wall of the CPA are integrally provided with vertical rods, and the outer wall of the vertical rod is provided with a primary locking point and a secondary locking point in sequence from bottom to top;

[0009] The buckle handle is integrally arranged at the center of the upper end of the locking rod.

[0010] Through the above technical solution, when in use, the CPA is pulled to the primary lock position, and the buckle hand will block the CPA, so there is no need to worry about the CPA falling off, and the primary lock position is kept unchanged; after the plug is matched with the socket, the lock rod is first flipped to engage with the horn on the socket, and the CPA is continued to be pushed from the primary lock point to the secondary lock point, so that the gap between the lock rod and the shell is filled with the CPA, so that the lock rod is fixed and cannot be disengaged, and the locking is completed; when the plug and socket need to be released, the CPA is pushed from the secondary lock point to the primary lock point to complete the unlocking.

[0011] In a preferred embodiment, a hand-grip position is provided on the upper surface of the CPA.

[0012] In a preferred embodiment, a cantilever buckle is integrally provided at the center of the lower wall of the CPA.

[0013] Through the above technical solution, during the locking and unlocking process, when locking, the cantilever buckle on the CPA will clamp the boss on the shell, thereby locking the position; when unlocking, the cantilever buckle on the CPA will disengage from the boss on the shell, thereby releasing the secondary lock position and returning to the primary lock position.

[0014] In a preferred embodiment, a through hole adapted to fit the handle is opened at the upper end of the CPA.

[0015] In a preferred embodiment, an observation hole is opened in the middle of the locking rod.

[0016] Through the above technical solution, whether it is in a locked state can be observed through the observation hole.

[0017] In a preferred embodiment, the buckle is formed by in-mold injection molding.

[0018] Through the above technical solution, the sharp metal hand button is wrapped with plastic after injection molding, thereby increasing the hand pressing area and solving the problem of easy injury to the hand when pressing the lock rod.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are: the utility model proposes a new CPA structure.

[0020] When in use, pull the CPA to the primary lock position, and the buckle handle will block the CPA, so there is no need to worry about the CPA falling off, and the primary lock position can be kept unchanged; after the plug is matched with the socket, first flip the locking rod to engage with the horn on the socket, and continue to push the CPA from the primary locking point to the secondary locking point, so that the gap between the locking rod and the shell is filled with the CPA, so that the locking rod is fixed and cannot be disengaged, thus completing the locking; when you want to release the plug and socket, push the CPA from the secondary locking point to the primary locking point to complete the unlocking. The CPA structure fixes the gap between the locking rod and the plug shell, so that the position of the plug and socket is stable after matching, the shaking is reduced, the locking rod will not fall off, and the seismic performance is enhanced.
