Abstract
A brake signal transmitter (10) includes a housing (11) and a liquid drainage system (20). The liquid drainage system (20) includes an opening in the housing (11) and a cover (30) that extends over or along the opening. The cover (30) includes at least one aperture that allows a liquid to be drained through the cover (30). The opening (21) of the housing (11) is arranged on a downward side of the housing (11) relative to a gravitational force the transmitter is mounted horizontally. The cover (30) may be a cap having a filter inserted therein. The filter may define a tortuous path to block ingress of water or debris into the housing. The cover may include resilient fingers that snap fit into a socket of the housing.
Claims20
A brake signal transmitter (10), comprising:
- a housing (11);
- and
- a liquid drainage system (20), comprising:
- an opening (21) in the housing (11);
- and
- a cover (30) configured to extend over or along the opening (21);
- wherein the cover (30) includes at least one aperture (33) configured to allow a liquid to be drained through the cover (30);
- wherein the cover (30) includes a plastic material;
- wherein the cover (30) includes an engagement structure (31, 32) that engages with the housing (11), wherein the engagement structure (31, 32) includes or is made of the plastic material;
- wherein the engagement structure (31, 32) includes at least one resiliently deformable cover portion (31), wherein the at least one resiliently deformable cover portion (31) provides a snap-fit engagement with the housing (20);
- and
- wherein the at least one resiliently deformable cover portion (31) comprise at least one resilient finger (31), and the at least one aperture (33) includes gaps (33) on opposite sides of the at least one resilient finger (31).
A brake signal transmitter (10), comprising:
- a housing (11);
- and
- a liquid drainage system (20), comprising:
- an opening (21) in the housing (11);
- and
- a cover (30) configured to extend over or along the opening (21);
- wherein the cover (30) includes at least one aperture (33) configured to allow a liquid to be drained through the cover (30);
- wherein the brake signal transmitter (10) includes a foreign matter ingress-reducing arrangement (24, 26, 37) configured to reduce or eliminate foreign matter ingress through the opening (21) into the housing (11)
- wherein the foreign matter ingress-reducing arrangement (24, 26, 37) includes a tortuous path (45), wherein the cover (30) delimits at least a portion of the tortuous path (45)
- wherein the foreign matter ingress-reducing arrangement (24, 26, 37) includes a filter (26)
- wherein the cover (30) is a cap (30), wherein the cap (30) includes a skirt portion (31, 35) that receives at least a portion of the filter (26) therein, wherein the skirt portion (31, 35) extends from a cap end portion (34);
- and
- wherein the foreign matter ingress-reducing arrangement (24, 26, 37) includes a resiliently deformable bias member (37) that biases the filter (26) and the cap end portion (34) away from each other, wherein the resiliently deformable bias member (37) is interposed between the filter (26) and the cap end portion (34) and biases the filter (26) toward an abutment surface (24) surrounding the opening (21).
A brake signal transmitter (10), comprising:
- a housing (11);
- and
- a liquid drainage system (20), comprising:
- an opening (21) in the housing (11);
- and
- a cover (30) configured to extend over or along the opening (21);
- wherein the cover (30) includes at least one aperture (33) configured to allow a liquid to be drained through the cover (30);
- wherein the brake signal transmitter (10) includes a foreign matter ingress-reducing arrangement (24, 26, 37) having a filter (26) biased toward an abutment surface (24) surrounding the opening (21);
- wherein the filter (26) is integrally formed as one piece with the housing (11) or the cover (30).
