In embodiments, such as generally illustrated in FIGS. 2A, 2B, 2C, 2D, 4A, 4B, 5, and 6, the connector 20 may include a first engagement portion 60, a second engagement portion 62, and/or a third engagement portion 64. The first engagement portion 60 may be connected to the first protrusion 50, the second engagement portion 62 may be connected to the second protrusion 52, and/or the third engagement portion 64 may be connected to the third protrusion 54. The first engagement portion 60, the second engagement portion 62, and/or the third engagement portion 64 may be configured to be at least partially received by the first surface 30, the second surface 32, and/or the third surface 34 (e.g., the circuit board 42 and/or the housing 40). For example and without limitation, the first engagement portion 60 may be at least partially received by the first surface 30. The first surface 30 (e.g., the housing 40) may include a first aperture 70 that may at least partially receive the first engagement portion 60 (see, e.g., FIG. 3). The first aperture 70 may include one or more of a variety of shapes, sizes, and/or configurations. The first aperture 70 may be substantially circular and/or rectangular. The shape and/or size of the first aperture 70 and the first engagement portion 60 may be substantially similar such that the first engagement portion 60 may engage the first aperture 70 (e.g., with minimal play between the first aperture 70 and the first engagement portion 60). The engagement portions 60, 62, 64 may, for example and without limitation, include substantially the same configuration (e.g., shape, size, material, etc.).
