Can anyone identify these connectors please

[ronbryan]

I need to identify these connectors (J10 and J350 on the first photo), so I can make some extension cables to allow access for fault investigation. They are from a Bose Companion 5 multimedia speaker system.

The pins are 1mm square and the contact pitch is 4mm. Does anyone recognise the connector type so that I can order some, or possibly have a few spare contact pins and sockets please.

The thing to remember is the headers come separately from the pins, which need crimping on. The pitch is 0.2" and they are readily available

True, but for test purposes you can buy headers with tags on - by the bucket load sourced from China of course...

I have some RS 178-9546 which is friction lock, not latch but should be O.K. for test purposes, they are IDC which means no crimping, Ihave 5 way versions as well which could be cut down for the 2 way connector.

Alternatively I have Farnell 143-161 which is crimp pin, I could crimp some pins on lengths of wire if you wanted.

I don`t have any of the pin headers but they are readily available, also off old duff boards.

I'm wondering if the connectors in my photos (post #1) are JST VH style, which are 3.96mm pitch, almost the 4mm I measured. I've ordered some two pin ones for trial.

Thanks for looking and for the offer of help Barry. Without having noticed your post above, I've steamed off and ordered some housings and socket contacts, which should arrive later this week. I may get back to you about your offer of crimping some wires on to the contacts if it proves difficult to insert them after soldering.

Hello Ron.

Are you looking for the ones with the brown, blue, green, yellow wires right? Molex is most likely the brand, check Mouser Electronics they have huge inventory.

I'd say so

[ronbryan]

Thanks for the recently posted interest Richard and Kevin.

I ordered some 2 and 4 way JST VH connectors and crimp socket contacts from ebay supplier komodo-electronics in Brighton last September and made up a 4 way extension cable for the speakers and a 2 way lead to connect 19V AC input from an external transformer (soldered crimps will go into the housing ok). This allowed the electronics (a circuit board bolted to a large heatsink) to be separated from the cabinet containing the Bose mains transformer and speakers. The fault was a rasping buzz from the speakers. The only analogue bit was the psu and power amp, all the rest was surface mount digital signal processing and DACs. I tested and resoldered some psu smoothers whilst examining the pcb, connected my test leads detailed above and measured psu voltages, only to find that the buzz had gone away. Most unsatisfactory, especially as I had spent ages poring over the multi-page circuit diagrams. I put the electronics back in the box, returned it to the owner and it has been working ok for five months.

The attached photo shows the speaker and low voltage AC extension leads (red/black at top centre of pcb) on the opened sound system).

if it's worked for 5 months then I think you fixed it!
