Electrical connection

1. An electrical connection comprising:

a first connector;

a second connector, configured to form a connection with the first connector, wherein the first and second connectors further comprise one or more fastening members configured to secure the connection between the first and second connectors;

a first wall surrounding the first connector;

a second wall surrounding the second connector, wherein the first wall is configured to fit inside the second wall when the first and second connectors are connected, and the first and second walls include leading faces comprising first and second chamfered portions, respectively, wherein the first and second chamfered portions are angled complementarily;

a seal disposed around the first wall; and

a first flange, from which the first wall protrudes axially, parallel to the connection axis (C-C), wherein the seal is compressed against the first wall, the first flange, and the second chamfered portion when the connection between the first and second connectors is secured by the one or more fastening members.

2. The electrical connection of claim 1 , wherein the first and second chamfered portions are angled at about 45° relative to the connection axis (C-C).

3. The electrical connection of claim 1 , wherein the first and second walls extend axially, parallel to the connection axis (C-C), and the axial extension of the first and second walls is greater than that of the first and second connectors, respectively.

4. The electrical connection of claim 3 , wherein the second wall has a greater axial extension than the first wall, for example, by 1 mm or greater.

5. The electrical connection of claim 1 , wherein the leading face of the first wall features a less-angled portion radially inward of the first chamfered portion ( 16 a ) relative to the connection axis (C-C).

6. The electrical connection of claim 1 , wherein the seal forms a hermetic seal between the first and second connectors when the first and second connectors are connected.

7. A method of connecting a control module to an actuator module using the electrical connection of claim 1 , wherein the method comprises:

stretching the seal to fit around the first wall;

disposing the stretched seal on the first wall such that it contacts the first wall and the first flange;

guiding the first wall inside the second wall using the first and second chamfered portions;

connecting the first and second connectors; and

compressing the stretched seal between the first wall, the first flange and the second chamfered portion by securing the connection between the first and second connectors using the one or more fastening members.

8. The method of claim 7 , wherein the seal is stretched to increase its perimeter by up to 5%.

9. The method of claim 7 , wherein the seal is stretched to increase its perimeter by between 3% and 5%.

10. The method of claim 7 , wherein the seal is stretched to increase its perimeter by about 3.5%.

11. An actuator assembly comprising:

an actuator module;

a control module; and

the electrical connection of claim 1 , configured to allow electrical communication between the control module and the actuator module, wherein the actuator module comprises one of the first and second connectors and respective first or second wall, and the control module comprises the other of the first and second connectors and respective first or second wall.

12. The actuator assembly of claim 11 , wherein the actuator assembly is configured to control one or more flight control surfaces of an aircraft.
