LMHC RANGE

DESCRIPTION & CHARACTERISTICS

INTRODUCTION This range of miniature bayonet connectors is designed to perform to the requirements of VG 95328 & MIL-C-26482 Series 1. The range comprises 9 shell sizes and 24 shell styles. Configuration of contacts varies from 3 to 61, spread across the nine shell sizes.

BASIC CONSTRUCTION

Connector shells are manufactured from aluminium alloy. The standard shell has a high resistance to corrosion with an olive drab chromate conversion over cadmium plate finish. Inserts are of polychloroprene, compounded to a WEALD specification. Operating temperature range is -55ºC to +125ºC. The connectors have gold plated, removable, crimp type contacts.

SECTION OF CONNECTORS

1 – Fixed shell 2 – Free inner shell 3 – Coupling nut 4 – Grommet 5 – Contact retention disk 6 – Pin insert 7 – Socket insert 8 – Plug contact 9 – Socket contact 10 – Waved washer 11 – Grounding fingers 12 – Gasket

LMHC RANGE

GENERAL INFORMATION

EMC SCREENING To satisfy electromagnetic compatibility (EMC) and electromagnetic pulse (EMP) requirements, free shells can be fitted with grounding fingers. Fixed & free shells can be fitted with accessories for screened cable terminations.

POLARISATION To avoid mis-mating with similar connectors which may be adjacently mounted, LMHC connectors may be polarised thus:

a) Angular Disposition of the Inserts within the Shell providing up to four different orientations other than Normal (N). These are designated W, X, Y, Z. See Table on page 9 for variations available in each planform, or;

b) The Position of Shell Keys and Keyways providing up to four different polarisations other than normal (N). These are designated B, C, E, F (see page 10). With these variations, inserts can be supplied only with the Normal (N) position.

LMHC STANDARD CHARACTERISTICS Environmental Category – 55/125/56 Low pressure severity – 44 millibars Number of Contacts – 3 to 61 Contact Termination – Crimp Maximum Current Rating at 85ºC:

a) per individual contact in isolation – Size 20 – 7,5 amp – Size 16 – 13,0 amps

b) per contact through all contacts simultaneously – Size 20 – 5,0 amp – Size 16 – 10,0 amps

Contact Finish – Gold Plated Working Voltage DC or AC Peak (at sea level) – 700 volts or 1200 volts Sealing – Environment Resistant with barrier or barrier and panel seal *Housing (Shell) Material – Aluminium Alloy *Housing (Shell) Finish – Olive drab chromate conversion over cadmium plate *Housing (Shell) – Other materials and finishes available. Please consult Sales.

ORIENTATION (INSERTS)

Connectors can be supplied with the moulding inserts in up to 4 alternative positions to ‘Normal’ (N) in relation to major key/keyway. The ‘Normal’ (N) position is when the ‘A’ contact is adjacent to the major key/keyway. See table below for orientations available for each size. Insert orientation is not preferred and is intended for replacement purposes only.

ASSEMBLY INSTRUCTIONS

WIRE STRIPPING Cut wire to length and strip 6,5mm of insulation from end for use with size 16 contacts. Strip 5,0mm of insulation from end for use with size 20 contacts. Take care not to cut or nick strands, if ends fray twist back to original form. CRIMPING WIRE TO CONTACT Use Crimp Tool (M22520/1-01) with Turret Head (M22520/1-02). Release and rotate Turret Knob to proper contact size (as per colour code) and lock adjust Selector Knob on handle to correct wire size (see table)

ASSEMBLY INSTRUCTIONS CONTACT INSERTION Select the proper insertion tool for the size of contact (see table). Slide rear accessory (if applicable) over wire bundle. Lay wire in groove of insertion tool and the tool tip butts against the contact shoulder.

Insert contact into the correct hole in the rear face of grommet. The insertion tool has to be in axial position to the insulator face area to prevent damage to contacts. Insert contact slowly into connector until it snaps in audibly. Withdraw tool at right angles to grommet surface until completely free of connector. Slightly pull cable and check the correct position of contact. Contacts must be inserted whether in circuit or not and the appropriate size sealing plug used behind any contacts that are not wired. Push the sealing plug in by hand until it is fully seated.

Insertion tool can damage insulator, contact or contact clip when it is not used according to instructions, when twisted or is itself damaged. If any part is damaged it must be replaced. After insertion of contacts, check connector on the mating side to ensure all contacts are at the same level.

PRODUCT SAFETY INFORMATION

These notes are intended to be used in conjunction with the Product Catalogue and Product Specification. Products may be safely used in the applications for which they have been designed and within the specified rating and environments. If products are exposed to condition outside the performance ratings or specified environments they may constitute a hazard. In particular it should be noted that:-

1. Material Content Circular Connectors generally use metalwork parts made of brass, aluminium, phosphor-bronze or steel, which, dependant on the particular application, may be passivated and protect with cadmium or zinc plate – in conjunction with chromated or anodised surface finishes. The insulating materials can either be natural or synthetic rubber, together with plastic or glass-filled plastic moulded parts. Contact materials vary but are usually made of brass, phosphor-bronze, alumel or chromel. 2. Electric Shock, Burns and Fire Hazard can occur if the product is used outside the specified parameters or if the product is damaged, wrongly wired or poorly assembled, or poorly integrated into larger equipments, or contaminated with conductive fluids. Live circuit terminations must be protected and live circuits never broken by disconnecting products. Hot spots may be created when resistance is increased due to damage or incorrect integration particularly soldering, or loose terminations. Overheating can cause breakdown of insulation, electric shock, burns or, ultimately, fire. In the event of fire noxious and/or toxic fumes may be released and, in these circumstances, any fire involving the product should be dealt with by personnel properly equipped. Connectors with exposed terminations or contacts should not be used on the current supply side of a circuit with exposed contacts on an unmated product. Before making a circuit live, the product and wiring should be checked to ensure there is no electrically conducting debris present. Circuit resistance checks should also be conducted before making the circuit live. Always ensure that connectors are assembled and wired by properly trained personnel. 3. Use, Transport and Storage of Products Care must be exercised to avoid damage to any part of the products during transporting, storage or use. Abnormal transit or storage conditions and abuse during installation can give rise to damage. Products should not be used in a damage condition. Improper storage (particularly of damaged products) can give rise to additional hazards particularly corrosion. Your attention is specifically drawn to the need for proper storage of products containing cadmium and you are advised to see the Guidance Note from the Health and safety Executive on Cadmium – Health and Safety Precautions. 4. Disposal of Products Product should not be burnt.

SAFETY RULES 1. FOLLOW THE GUIDELINES GIVEN. 2. ALWAYS PROTECT LIVE CIRCUITS AND NEVER DISCONNECTOR A LIVE CONNECTOR 3. NEVER USE A DAMAGED CONNECTOR. 4. NEVER BURN DISCARGED CONNECTORS.
