The Connector Backshell supports a connector termination while managing cable exit, strain relief, shielding, sealing, and service access. This page is an unbranded request-for-quotation entry for an application-specific product type, not a fixed stocked model. Share the assembly, interface, environment, quantity, and documentation requirements so the proposed supply boundary can be reviewed before quotation.
Connector Backshell Selection and RFQ Requirements
A backshell that fits mechanically can still conflict with shielding, bend radius, sealing, or installation space. The review begins with the function of the item in the robot, then separates mechanical fit, electrical or material requirements, operating conditions, service access, and verification. Similar-looking parts are not treated as interchangeable. Drawings, connector schedules, photographs of mating interfaces, and revision-controlled bills of materials are more useful than a product-family name alone.
How to specify the Connector Backshell
Provide the intended function and identify the two interfaces or assembly boundaries that the item connects. The initial review should address the following points:
- Connector Shell Family And Accessory Thread: provide the drawing, schedule, or requirement that controls this decision.
- Straight Or Angled Cable Exit: provide the drawing, schedule, or requirement that controls this decision.
- Shield Termination And Bonding Method: provide the drawing, schedule, or requirement that controls this decision.
- Bundle Diameter, Clamp Range, And Environment: provide the drawing, schedule, or requirement that controls this decision.
Supply the full connector designation, shell size, accessory interface, cable bundle diameter, shield construction, and available exit envelope. A section or installation photograph should show nearby covers, fasteners, bend restrictions, and tool access. For shielded assemblies, define whether the termination is overall or individual, how the braid or foil is prepared, and where chassis bonding occurs. For sealed entries, identify the cable jacket, environmental exposure, and mating arrangement rather than asking for a generic waterproof accessory.
Configuration, Interfaces, and Quoted Scope
A connector backshell is quoted against the exact connector interface and cable construction. Clamp hardware, boots, adapters, braid termination parts, and sealing accessories are listed separately unless included. The quotation should identify the exact deliverable, quantity, revision, and supplied state. It should also list excluded mating parts, customer-provided items, required tools, documentation, and acceptance evidence. Options may be compared, but they remain alternatives until a specific configuration is approved.
The word backshell covers several termination accessories. A d sub backshell uses a different connector interface from a circular connector backshell; neither can be selected from cable diameter alone. EMI backshells additionally require a defined shield and bonding method, so electrical screening performance is reviewed with the connector and cable construction.
Connector Backshell verification before quotation
- Confirm product identity from controlled drawings, interface definitions, or an approved sample.
- Review mechanical, electrical, material, environmental, and motion requirements as separate evidence sets.
- Record every included component and accessory, including both mating halves where applicable.
- Agree the inspection, continuity, dimensional, visual, functional, or documentation checks relevant to the item.
- Freeze the approved revision before production quantities or interchangeability are discussed.
An Engineering reference is provided as background for preparing the inquiry. It does not define the specification of a proposed item or certify that a generic product meets the application.
Inquiry Checklist
- Robot subsystem, installation location, function, and development phase
- Interface drawings, connector or part identities, revision, and mating direction
- Operating duty, routing or load conditions, environment, and maintenance expectations
- Required included items, tools, files, labels, packaging, and inspection documents
- Prototype quantity, production estimate, destination, and target schedule
Submit the available information through the RobotPiece quote list or contact page. Related product-type inquiries are organized under the Hardware category.
A D-sub backshell inquiry should include the connector hardware, screw arrangement, cable exit, and enclosure clearance. A circular connector backshell instead depends on its shell accessory interface, coupling method, and available clamp envelope. For EMI backshells, provide the cable shield construction and chassis-bonding concept so that the termination method can be reviewed with the complete assembly.
Some drawings and procurement records write the same accessory as a d sub backshell without a hyphen; the controlled connector identity should resolve that naming difference. Where EMI backshells are required, the review should also record shield coverage, termination hardware, bonding surface preparation, and inspection access instead of treating screening as an implied feature.
Frequently Asked Questions
How do I choose straight versus angled cable exit?
Provide the installed connector orientation, available envelope, cable route, minimum bend requirement, and service access. The exit direction should reduce strain without obstructing mating hardware or adjacent components.
Does a backshell automatically provide shielding and sealing?
No. Shield termination, environmental sealing, strain relief, and cable support are separate functions. The exact configuration and required accessories must be stated in the quotation.
Does the illustration define the delivered connector backshell?
No. The cover is a conceptual product-type illustration, not a photograph of a confirmed model. Actual dimensions, materials, connectors, finish, markings, included items, and supplied documents must be stated in the approved quotation.
