Adapter arrangement

摘要

A first adapter arrangement includes a housing having a sealing end supporting the housing in a vertical wall opening of a casing containing an electronics device, and a connecting end extending externally of the casing for connection with the housing of a companion adapter arrangement. A pair of resilient generally-annular longitudinally-spaced seal members are mounted concentrically about the adapter housing sealing portion for sealing the space between the adapter housing outer surface and the adjacent surface of the casing wall opening. An electrical connector mounted in a through passage contained in the adapter housing includes a conductor contact end connected with the conductors of the electrical device, and a connector contact end adapted for connection with the corresponding contacts of a companion second adapter arrangement. A fastening device serves to connect together the adjacent ends of the adapter housings of the first and second arrangements.

主权项

1. An adapter arrangement for mounting an electrical connector in a sealed electronics casing, comprising:
(a) a rectangular open-topped first electronics casing (5) having a horizontal bottom wall, and two pairs of vertical side and end walls that cooperate with said bottom wall to define a chamber (52),
(1) at least two of said vertical side and end walls having top edge portions containing access openings (50);(2) each of said access openings including a wall surface provided with two continuous longitudinally-spaced ribs (500) that extend the entire surface of said opening; (b) an electrical device (40) arranged in said electronics casing chamber, said electrical device including a plurality of electrical conductors (41); (c) a pair of adapter housings (11, 11′) having sealing ends (13, 13′) inserted within said wall openings, respectively, and connecting ends (14, 14′) extending outwardly from said first electronics casing, said adapter housings containing longitudinal through passages (114, 114′); (d) an adapter sealing arrangement for sealing the space between each adapter housing and the associated electronics casing opening, including a pair of longitudinally-spaced resilient continuous annular first seal members (21, 22) mounted concentrically about said adapter housing sealing end for sealing engagement with corresponding rib surfaces on the associated electronics casing access opening, respectively; (e) a pair of electrical connectors (12, 12′) mounted in said adapter housing through passages, respectively, each of said electrical connectors including a connector body having a contact end (120, 120′) including a plurality of internal conductor contacts connected with said electrical device conductors, and a connection end (121, 121′) including a plurality of external conductor contacts (121a; 121b); (f) a connector sealing arrangement for sealing the space between each connector body and the wall of the associated adapter through passage, comprising a second annular seal member (S, S′) mounted concentrically about said connector body for sealing engagement with the adjacent wall surface of the associated adapter housing through passage; (g) a cover member (55) seated on said electronics casing to close said electronics casing chamber, said cover member cooperating with said first seal members to close said access openings, thereby to protect the electronics housing chamber from dust and moisture; and (h) a fastening arrangement (23, 23′) operable to fasten said adapter housing connecting end with the connecting end of a companion adapter housing.
