4 PIN MAGNETIC CHARGING CABLE FOR TOYS
This 4 pin magnetic charging cable is a complete cable assembly designed for children’s electronic toy charging interfaces. The visible cable head uses a compact rectangular housing with four electrical contact positions arranged in one linear row.
The four contacts are assigned according to the approved Pin Map. Charging is the confirmed function of this product, while polarity, auxiliary contact functions, voltage, current capability, cable construction and opposite-end termination are defined for each project.
Magnets primarily assist capture and retention during mating. Final position, alignment and seating should be controlled by the mating housing and mechanical geometry. The required release behavior should be selected according to the toy structure, cable direction and intended user interaction.
The magnetic charging head uses a compact rectangular form with four contacts arranged along one row inside a recessed mating area.
This architecture can be evaluated for electronic toys where a detachable charging cable and a compact external charging interface are required.
Pin Count Four electrical contact positions
Contact Layout Single row / linear arrangement
Head Shape Compact rectangular housing
Application Children’s electronic toy charging
The approved drawing should identify Pin 1, viewing direction, contact pitch, polarity and the electrical function of all four contact positions.
Four contacts do not automatically mean that all four positions are connected in parallel for charging. Depending on the toy electronics, contacts may be allocated to power, return, detection, identification or other defined functions.
The cable-side and device-side drawings should use the same viewing reference so the contact assignment cannot be mirrored during assembly.
The magnetic structure helps the charging head approach and remain engaged with the mating interface.
Capture force, retention force, separation force and peel force describe different mechanical conditions and should be specified separately when they are relevant to the finished toy design.
Stronger magnetic retention is not automatically better. The required holding force should be balanced against the intended cable-release direction, toy mass, enclosure strength, strain relief and expected user handling.
Final alignment and seating should be controlled by the mechanical mating geometry rather than by magnetic attraction alone.
The image confirms four electrical contact positions, but the internal spring-loaded structure and mechanical travel should be confirmed from the approved contact drawing.
If spring-loaded pogo contacts are used, working stroke and total travel must be treated as different parameters. Working stroke defines the intended operating compression, while total travel represents the available mechanical movement of the contact.
The housing and mating surfaces should establish the final mechanical seating condition. Spring contacts should provide electrical connection and controlled compliance rather than act as the primary mechanical hard stop.
Charging-current capability cannot be determined from the four-pin count or contact size alone.
Power Source → Opposite-End Termination → Cable Conductors → Magnetic Charging Head → Assigned Electrical Contacts → Device-Side Interface → Toy PCB → Charging Circuit → Battery / Load
Vdrop = I × Rpath
Ploss = I² × Rpath
Cable length, wire gauge, termination resistance, contact resistance, mating condition, device-side PCB copper and temperature rise should be evaluated together before a continuous-current rating is released.
If multiple contacts are connected in parallel, current sharing must also be evaluated because resistance and compression differences can cause unequal current distribution.
The magnetic charging head is only one part of the complete charging cable assembly.
Cable length, conductor count, wire gauge, outer jacket, cable flexibility, strain relief and opposite-end termination should be defined together with the electrical and mechanical requirements of the toy.
The cable outlet and strain-relief structure should also be reviewed with the expected handling direction so the cable load is not transferred unintentionally to the device enclosure or electrical contacts.
USB-A, USB-C, DC plug, bare wire or another custom termination should only be stated after the approved cable drawing confirms the actual configuration.
A magnetic charging cable intended for a children’s toy should be evaluated as part of the complete finished product rather than treated as a stand-alone safety-certified interface.
Final validation may need to consider electrical conditions, accessible surfaces, temperature rise, cable handling, detachable components, enclosure geometry, charging behavior and the requirements of the intended sales market.
Magnetic retention, materials, plating or connector appearance alone do not establish toy-product safety or regulatory compliance.
Any product-level compliance statement should correspond to the defined finished toy configuration and supporting test documentation.

This 4 pin magnetic charging cable can be evaluated for children’s electronic products that require a detachable charging interface with a compact rectangular connector head.
Final application suitability depends on the approved electrical design, mechanical interface, cable construction, magnetic release behavior and complete finished-product validation.
It is a magnetic charging cable assembly with four electrical contact positions. This version uses a compact rectangular head with the contacts arranged in one linear row for project-specific toy charging integration.
The exact electrical function of each contact is defined by the approved Pin Map. Contacts may be allocated to power, return, detection, identification or other project-specific functions.
Not necessarily. Parallel contact allocation must be defined by the electrical design. If contacts are paralleled, current sharing should be validated in the complete assembly.
Charging current is project-specific and must be validated through the complete conductive path, including the source termination, cable conductors, contact interface, toy PCB and charging circuit.
Not automatically. Retention should be balanced with separation and peel behavior, cable direction, toy mass, enclosure strength and intended handling conditions.
This should not be assumed. Release behavior depends on retention force, peel direction, cable routing, device mass and mechanical construction and should be validated in the finished product.
Working stroke should be defined by the approved contact drawing if spring-loaded contacts are used. It is different from the total mechanical travel of the contact.
Toy-product safety or regulatory compliance should not be inferred from the connector alone. The finished toy configuration and its intended sales market must be validated with the required product-level documentation and testing.
Yes. Cable length, wire construction, strain relief and opposite-end termination can be defined according to the approved project requirements.
Provide the Pin Map, voltage, continuous and peak current, cable length, wire gauge, charging-head dimensions, opposite-end termination, contact requirements, magnetic release requirements, device-side drawings and finished-product validation requirements.

This product page presents a CTP magnetic cable assembly configuration for engineering reference. Final dimensions, electrical ratings, materials, magnet structure, sealing level and reliability targets are not universal values; they are confirmed against the approved drawing, installation condition and model-specific validation plan.
CTP reviews the application and prepares a drawing or specification for approval before sample production. Test scope, acceptance criteria and report format should identify the model, sample status, method, conditions, result and review date.
Yes. Customization can cover geometry, contact layout, materials, cable construction, magnetic structure, sealing and appearance. Feasibility depends on the application and approved specification.
