H15EDGKDM-3.5 Terminal block connector with side screw

H15EDGKDM-3.5 Terminal block connector with side screw

1.Internal Electrical Connections (Screwless)

Method: Identical to standard models, utilizing spring pressure technology ("push-in" or "press-fit"). Each pin has a corresponding spring clip to hold the wire, enabling fast and reliable electrical connections.

Purpose: To provide excellent conductivity and vibration resistance, and to facilitate quick wiring.

2.External Mechanical Locking (with Screws)

Location: There are typically metal threaded inserts on both the left and right sides of the plastic connector housing, each fitted with a small screw (usually M2 or M2.5 size).

Function: After the connector is fully inserted into the corresponding socket (or base), these two screws are tightened. The tips of the screws will press against or lock into corresponding grooves or locking mechanisms on the socket housing.

Purpose: To provide strong mechanical locking force, preventing the connector from becoming loose or detached from the socket due to strong vibration, accidental pulling, or prolonged use.

1.Type and Pole

Type: Pcb Pluggable Screw Terminal Block

Pole:

It primarily addresses the following pain points:

Reliability in vibrating environments: In scenarios such as rail transit, mining machinery, heavy vehicles, and vibrating screens, the plastic clips of ordinary connectors may fatigue or detach due to prolonged vibration. Screw locking fundamentally eliminates this problem.

Prevention of accidental disconnection: In areas with high traffic or where accidental bumping is likely, screw locking prevents the connector from being unintentionally dislodged, thus preventing unexpected equipment downtime.

Ensuring critical signal/power connections: For critical control circuits, safety circuits, or main power circuits where interruptions are unacceptable, using a design with locking screws is a "double-insurance" engineering practice.

Extending the overall lifespan of the connector: This reduces wear and tear on the socket pins caused by repeated minor movements.

Typical Application Scenarios

This design is typically used in applications where extremely high connection reliability is required:

Heavy machinery and equipment: Control cabinet connections for construction machinery (excavators, cranes), agricultural machinery, and port machinery.

Rail transportation: Interconnection of control units inside train carriages, requiring resistance to continuous vibration and shock.

Energy and power: Wind turbine pitch/yaw control cabinets and photovoltaic inverters, where environmental vibration is significant and maintenance is difficult.

Critical process control: I/O stations involved in safety interlocks (ESD) or critical process control in the chemical, oil, and gas industries.

Mobile equipment and vehicles: Electronic system connections for special vehicles and military equipment.
