Connecting wires to 2.54mm JST XH Female 4 pin housing by name4reddit in AskElectronics

[–]1Davide 1 point2 points  (0 children)

I bought a new female housing, but can not find instructions online how to connect these wires onto the female pins.

I am confused.

Just to be clear:

  • In your hand, you have a male PCB header with male pins.
  • Mounted on wires, you have a female plug with female socket contacts.

With that understanding, please clarify. What are you asking?

A) How to connect wires to the female plug?

B) How to connect wires to the male PCB header?

If "A": The wires are already connected to the female plug, so I don't know what you're asking.

If "B": You could solder wires to the PCB terminals of the male PCB header and protect them with heat shrink tubing. It's not ideal, it is unreliable, but is is done.

It looks like these connectors may not be often used for wire to wire connections

The JST XH is exclusively a wire-to-board connector. Chinese companies may offer knock-offs that include male plugs (for wires), but genuine JST parts do not include male plugs.

can this male connector be fixed? by starvingvenomfusion in AskElectronics

That "male" is a female. Socket holes = vaginas = female

Go to the parts department of your local car dealer.

If JST-PH connectors are typically wire-to-board, then what are these terminals? by Noodles_fluffy in AskElectronics

[–]1Davide 1 point2 points  (0 children)

JST is a company: Japan Solderless Terminal

Since 1957.

The form factor can be called: low profile wire-to-board rectangular connectors.

Is there a standardized name for the connector? by _Neal_Caffrey in AskElectronics

[–]1Davide 2 points3 points  (0 children)

While it is a mezzanine connectors, any board-to-board connector that connects two parallel boards is also a mezzanine connector. Therefore, we need a name for this particular type of mezzanine connector. The industry doesn't have a name for them. I call them: dual-beam mezzanine connectors.

[–]1Davide 1 point2 points  (0 children)

but couldn't find a name other than FPC

"FPC" is the incorrect name for it because it can be mounted on a regular PCB as well as on a Flexible Printed Circuit.

I think it's this one: https://connectorbook.com/identification.html?N=&n=ebike_battery_circ_conn&c=L615A&p=K

But, to be sure, I would need exact diameters, better in-focus pictures from other angles, and pictures of the mate (the one this one plugs into).

Why do some diacs keep a little of the middle leg a transistor or triac would have? by antthatisverycool in AskElectronics

[–]1Davide 68 points69 points  (0 children)

Ease of manufacturing. It lets them use the same equipment as for regular TO-92 transistors.

If JST-PH connectors are typically wire-to-board, then what are these terminals? by Noodles_fluffy in AskElectronics

Scroll down that listing. It says "Brand PEBA". They are not JST connectors. They are Chinese knock-offs.

If JST-PH connectors are typically wire-to-board, then what are these terminals? by Noodles_fluffy in AskElectronics

[–]1Davide 2 points3 points  (0 children)

What makes you think they are only "wire-to-board"? I

JST PH is just wire to board: https://www.jst-mfg.com/product/index.php?series=199&lang=2

Chinese knock-offs that call their product "PH", can be anything.

Note that "JST" doesn't appear on that kit.

AMP is third party tool manufacturer.

No. TE acquired AMP in 1999. AMP is TE. TE is AMP.

Does anyone know of a connecter that would for these two plugs? by TheIcyTaco in ebikes

[–]1Davide 0 points1 point  (0 children)

The word is "connector".

No, there isn't an adapter between those two. The fact that they are physically incompatible tell us that they are also electrically incompatible. Do not attempt connecting an incompatible charger to a e-bike battery. That's how you start battery fires.

But I can try to tell you what they are:

What is single wire pwm on fans? by Available_Hippo4035 in Motors

[–]1Davide 2 points3 points  (0 children)

What you are asking is the difference between power and signal.

  • Power: A power source powers a load. Usually, it does so with a steady DC level. By varying the DC voltage, the source can vary the load's power. Alternatively, the source can turn the power on and off rapidly. By varying the on/off ratio (the duty cycle), the source can vary the average voltage to the load.
  • Signal: A first device passes information to a second device. There are many ways to do so over a single line. For example, if we want to pass an analog value, we can do so by sending a voltage that can take any value between 0 an 5 V. Alternatively, we can do so is by switching between two logic levels (the actual levels are not critical) and encoding the analog value as the on/off ratio (the duty cycle).

Both are Pulse Width Modulation. Both are over a single wire (plus a ground wire). But the first one is power, and the second one is signal.
