wherein the curved or bent portion of each contact pin is free to move in said space, and

wherein each curved or bent portion comprises:

a first, straight section extending in a first direction from one of the contacts;

a second section extending from the end of the first section opposite the contact and away from the first direction;

a third section extending from the end of the second section opposite the first section and toward the first direction; and

a fourth, straight section extending from the end of the third section opposite the second section and in the first direction.

2. The female electrical connector of claim 1 , wherein:

the first and second sections are positioned at a first angle to each other;

the second and third sections are positioned at a second angle to each other; and

the third and fourth sections are positioned at a third angle to each other.

3. The female electrical connector of claim 2 , wherein:

each angle is an obtuse or acute angle; and

the transition between at least one of the first and second sections; the second and third sections; and the third and fourth sections is sharp, curved, or both.

4. The female electrical connector of claim 1 , wherein:

the second section extends away from the first section at a first, obtuse angle; and

the first angle is sharp, curved, or both.

5. The female electrical connector of claim 1 , wherein:

the third section extends away from the second section at a second, obtuse or acute angle; and

the second angle is sharp, curved, or both.

6. The female electrical connector of claim 1 , wherein:

the fourth section extends away from the third section at a third, obtuse angle; and

the third angle is sharp, curved, or both.

7. The female electrical connector of claim 1 , wherein the first and fourth sections are aligned.

8. The female electrical connector of claim 1 , wherein the female connector is a USB connector or an RJ connector.

9. The female electrical connector of claim 1 , wherein the substrate is a PCB.

10. The female electrical connector of claim 1 , wherein electromagnetic interference (EMI) shielding defines one or more of the plurality of walls.

11. The female electrical connector of claim 10 , wherein the EMI shielding:

defines a top wall of the housing; and

covers side walls of the housing.

12. The female electrical connector of claim 1 , wherein the contact pins extend from a bottom wall of the housing.

13. The female electrical connector of claim 1 , wherein each channel is defined by a pair of adjacent projections.

14. The female electrical connector of claim 1 , wherein:

an upper section of the contact pin passes through one of the pair of channels; and

a lower section of the contact pin passes through the other of the pair of channels.

15. The female electrical connector of claim 1 , wherein the straight sections of the contact pin on opposite sides of the curved or bent portion are aligned.

16. A female electrical connector comprising:

a plurality of walls defining a housing, a female connector inside the housing, and an opening configured to facilitate insertion of a mating male connector into the female connector;

contacts of the female connector positioned in the opening of the housing; and

contact pins extending from the contacts of the female connector through at least one of the plurality of walls of the housing for connection to a substrate,

wherein each contact pin includes a curved or bent portion disposed in a space between a pair of channels of the housing through which straight sections of the contact pin on opposite sides of the curved or bent portion pass,

wherein the curved or bent portion of each contact pin is free to move in said space, and

wherein each contact pin includes another curved or bent portion disposed in another space between another pair of channels of the housing through which straight sections of the contact pin on opposite sides of the other curved or bent portion pass.

17. A female electrical connector comprising:

a plurality of walls defining a housing, a female connector inside the housing, and an opening configured to facilitate insertion of a mating male connector into the female connector;

contacts of the female connector positioned in the opening of the housing; and

contact pins extending from the contacts of the female connector through at least one of the plurality of walls of the housing for connection to a substrate,

wherein each contact pin includes a curved or bent portion disposed in a space between a pair of channels of the housing through which straight sections of the contact pin on opposite sides of the curved or bent portion pass,

wherein the curved or bent portion of each contact pin is free to move in said space, and

wherein the curved or bent portion of each contact pin is part of an otherwise straight section of the contact pin.
