DC 4017 Straight to Right Angle Combo Cable
This dc 4017 combo cable has a straight 4.0 x 1.7 mm male plug on one end and a right-angle female socket on the other, so a straight PSU lead can enter a tight chassis.
No kinking at the jack, no side load on the solder fillet.
Overview
A dc 4017 combo cable carries two different body styles on one lead: a straight 4.0 x 1.7 mm male plug on the source end and a right-angle 4.0 x 1.7 mm female socket on the device end. It answers a mechanical problem rather than an electrical one – the barrel jack on a compact device often sits flush against a wall, a panel or another connector, and a straight plug simply will not fit there without kinking the cable or levering the jack off the board.

Confirm the barrel before anything else
4017 sits in the middle of the family, which makes it easy to confuse with its neighbors in both directions. A coaxial power connector callout is outside diameter first, then the center contact – 4.0 mm and 1.7 mm here. The table is a measurement guide; the device rating label or the jack on the board is the authority.
| Callout | OD x ID (mm) | Typical equipment | Fits a 4017 jack? |
|---|---|---|---|
| 5525 | 5.5 x 2.5 | Laptop and industrial supplies | No |
| 5521 | 5.5 x 2.1 | CCTV, routers, LED drivers | No |
| 4017 | 4.0 x 1.7 | Compact consumer gear, mini laptops, portable DVD | This build |
| 35135 | 3.5 x 1.35 | Mini routers and small printers | No – too small to seat |
| 3513 | 3.5 x 1.3 | Mini travel routers, label printers | No |
Both ends of this assembly are the same barrel size, so the adapter does not change what you can plug into – it changes the geometry. That is worth stating plainly because it is the usual source of a wrong order: this is not a converter between sizes. If you need to bridge two different barrel sizes, ask for the adapter set instead.
Why the right-angle end earns its place
A straight plug needs clearance in front of the jack equal to its own length plus the bend radius of the cable. Where that clearance does not exist, installers do one of three things, and all three fail: they bend the cable hard at the strain relief, they let the plug body press against the panel so the jack takes a permanent side load, or they unplug and replug until the solder joints crack. A right-angle socket moves the exit 90 degrees and puts the bend inside a molded body that is designed to take it.
| Failure you see | Real cause | What fixes it |
|---|---|---|
| Device cuts out when the cable is moved | Side load on the jack, cracked solder fillet | Right-angle socket so the load goes into the mold |
| Cable jacket splits at the plug | Bend radius tighter than the cable allows | Right-angle body with a longer strain relief boot |
| Plug will not fully seat | Panel or adjacent connector in the way | Right-angle body, with the exit direction specified |
| Plug backs out over time | Cable weight pulling on a straight body | Route the cable, or specify a right-angle with a molded support |
Specify which way the right-angle exits
A right-angle body can leave the cable in four directions relative to the device face, and picking the wrong one puts you back where you started. On the drawing, state which way the cable should run once the socket is mated – up, down, left or right as you look at the device panel. A photo of the installation beats a written description every time.
Also state the length you need from the elbow to the straight plug, measured along the route the cable will actually take, not point to point. Combo cables are usually short and a 10 cm error is the difference between tidy and strained.
Typical applications for this dc 4017 combo cable
- Wall-mounted monitors and signage players where the jack faces the wall
- Compact laptops and portable DVD players with a flush barrel jack
- Rack shelves and patch panels where the next connector is 5 mm away
- Kiosk and point-of-sale enclosures with no rear clearance
- Retrofit work where the original straight lead has already damaged the jack
How to specify your build
- Exit direction of the right-angle body, with a photo if possible.
- Length measured along the real route.
- Barrel size confirmed against the device – 4017 here.
- Polarity – center positive unless stated otherwise.
- Load current, so the conductor is sized to the run.
- Jacket color and any print.
- Quantity – sample or production.
Workmanship and testing
DC 4017 Straight builds are assembled and inspected to IPC/WHMA-A-620 Class 3 criteria, with ISO 9001 as the quality system over 32 to 12 AWG work. Every DC unit is checked for 100% continuity and pinout before packing, and seal checking is quoted whenever an ingress rating is on the drawing.
Every production run can ship with RoHS and REACH declarations and the electrical report agreed at quotation; see certifications and material declarations. UL styles and other named approvals are built to drawing: we source to the style you specify and document it, rather than asserting a listing we do not hold. Exit direction is a tooling decision, not a field bend see right-angle overmold tooling options for the forms we mold and when each one makes sense. Related reading: what outdoor duty does to a jacket. Tooling is quoted separately, cut in-house rather than brokered out, and owned by you.
Custom builds and ordering
DC 4017 Straight prototype builds start from 1 to 50 pcs and are out in 3 working days. Production is quoted from 500 pcs at 14 working days after sample approval. Tooling not already held adds around 10 working days. Your part number and labeling go on OEM and ODM DC shipments, and material certificates with first-article reports are available.

Frequently Asked Questions
Does this convert between barrel sizes?
No. Both ends are 4.0 x 1.7 mm. What changes is the body style, from straight to right angle, so the cable can leave the device in a different direction.
Which way does the right-angle end exit?
Whichever way you specify. There are four orientations and we mold to the one on your drawing. Send a photo of the installation and we will confirm before tooling.
Can I get it in white or another color?
Yes. Jacket color, housing color and length are all set per build, and we can match a housing color to your brand.
Is 4017 the same as 4.0 x 1.7 mm?
Yes – the callout is just the two dimensions run together. Outside diameter first, then the center contact diameter.
