Standard tail accessories (suitable for GJB599Ⅲ series connectors)
These accessories comply with the national military standard GJB1784 (equivalent to the U.S. military standard MIL-C-85049).
Note:
The "J1784" and "J1784A" mentioned in the accessory model numbers are equivalent and interchangeable.
When using these accessories, at least one of the following anti-loosening measures should be taken:
① Pass a safety wire through the safety hole for anti-loosening;
② Apply thread locker to the threads at the tail of the product and tighten the connecting nut for anti-loosening;
③ Use a heat shrink tube to shrink the entire accessory for anti-loosening.For accessories with set screws, apply thread locker to the set screws before tightening them.
If the product with which the cable accessory is compatible is equipped with a No. 8 contact, it is necessary to choose a longer cable accessory such as the J1784/38H or J1784/18 type to avoid interference between the contact locator and the cable accessory.

Example of Model Marking
J1784/18-09S01, where "J1784" is the main series name, "18" indicates the type - straight shielded cable clamp (for clamping shielded cables with accessories), "09" is the housing number, "S" denotes stainless steel passivation for the housing coating. The length of the accessory is specified as 64.4 mm.
Rotation-proof, shielded mesh clamping, and cable clamping accessory that securely wraps and seals the wire harness, providing a connection function between the shielded mesh and the tail accessory. It ensures the connector's high environmental resistance and electromagnetic shielding performance, making it suitable for harsh environments. This cable accessory comes in various lengths, catering to applications requiring longer attachments, such as mixed high and low-frequency installations. It is recommended to use pre-assembled cables with this accessory.
