Different locking components and features of the J30J series connectors

1. Type L, K, and K1

• These three types mostly serve as auxiliary supporting locking components, often used in conjunction with the mainstream P-series locking components. The K1 type is particularly special, compatible only with the P1-type locking component. In contrast, the L and K types have broader adaptability, capable of matching multiple P-series components such as P, P0, and P3. They are suitable for certain modified versions of J30J products; for example, the J30J-C series can only be paired with L, K, and K1-type locking components, ensuring connection stability when the outlet direction of the connector is 90° to the insertion direction.

2. Front-panel Mount P-series (P, P1, P8, P9, etc.)

• Types P, P8, and P9: Exclusive to front-panel mounting, they must be used with L or K-type locking components. In terms of adaptability, J30J products with anti-rotation slots or shielded cable clamps (such as the J30J-D series and J30J-AD series) can only be matched with these locking components. The anti-rotation design of their shell flanges prevents screws from rotating during installation, improving mounting accuracy.
• Type P1: Also a front-panel mounting adapter component, its core feature is the exclusive matching with the K1-type locking component. This differentiates it from the matching rules of P, P8, and P9 types, meeting assembly precision requirements in specific scenarios.
• Types P5 and P10: Specifically designed for straight plug printed circuit boards (PCBs), they are only suitable for front-panel mounting scenarios with compatible PCB thicknesses and must be used with L or K-type locking components. They adapt to connectors with various contact counts (9–100 contacts), fulfilling the installation needs of straight plug PCBs.

3. Rear-panel Mount P-series (P0, P3, P4, P11, etc.)

• Types P0, P3, P4, and P11: General-purpose rear-panel mounting locking components, requiring pairing with L or K-type components. For plugs (sockets) with cable clamp assemblies, the mounting panel thickness should be adjusted according to the formula "mounting panel thickness + 0.7" to avoid the cable clamp affecting installation fit. They are suitable for most conventional rear-panel mounting scenarios.
• Type P2: Has strict installation restrictions, applicable only to 1mm-thick mounting panels and rear-panel mounting of 90° bent plug PCBs, requiring matching with L or K-type components. It adapts to connectors with 9–100 contacts, focusing on specialized mounting scenarios for bent plug PCBs with thin mounting panels.
• Type P14: Suitable for 3mm-thick mounting panels, also used for rear-panel mounting of 90° bent plug PCBs and paired with L or K-type components. It forms a thickness-differentiated adaptation with the P2 type, covering the mounting needs of bent plug PCBs with different panel thicknesses.

4. Special Function Types (P7, V, V1)

• Type P7: Specifically designed for 90° bent plug PCBs, exclusive to front-panel mounting and requiring matching with L or K-type components. It adapts to various contact count specifications, filling the specialized locking demand for front-panel mounting of bent plug PCBs.
• Types V and V1: Both used in scenarios where strong locking is not required. The V type is suitable for PCBs with a thickness not exceeding 2.5mm and only applicable to J30J standard straight plug PCB products without locking requirements. The V1 type follows a similar non-locking adaptation logic, meeting the needs of low-intensity fixation, frequent disassembly, or light-duty connection scenarios.
