Case member having connector portion
View Patent ↗There is provided a case member having a structure for preventing the pushing-out of a seal member caused by gas leakage within a connector portion and also for preventing an annular lip portion of the seal member from falling when fitting the connector portion and a mating connector to each other. In the seal member 13 , the annular lip portion 13 f extends in a direction of connecting of the connector portion 18 to the mating connector in surrounding relation to electrical contact portions 19 a of connection terminals 19 . A seal member holder 15 is fitted on an outer peripheral surface of the connector portion 18 . An annular groove 15 f for receiving the annular lip portion 13 f of the seal member 13 is formed in this seal member holder 15.
1. A case member, comprising:
a case portion that has an electrical part chamber formed therein for receiving an electrical part;
a connector portion that is integrally formed with the case portion, and includes:
a seal member chamber;
a partition wall formed between the seal member chamber and the electrical part chamber to separate the seal member chamber from the electrical part chamber of the case portion; and
a connection terminal fixed to the partition wall so as to pass through the partition wall, and has an electrical contact portion projecting into the seal member chamber;
a seal member having a terminal hole disposed within the seal member chamber so that the electrical contact portion of the connection terminal passes through the hole of the seal member; and
a seal member holder that is fitted on an outer peripheral surface of the connector portion,
wherein the seal member has an annular lip portion at an edge thereof which has an inner peripheral surface and an outer peripheral surface extending in a connection direction in which the connector portion connects to a mating connector so as to surround the electrical contact portion of the connection terminal; and
wherein the seal member holder has an inner annular groove which receives the annular lip portion of the seal member so as to support the inner peripheral surface and the outer peripheral surface of the annular lip portion when the seal member holder is fitted on the connector portion.
2. The case member according to claim 1 , wherein the electrical part is a Charged Coupled Device (CCD) camera unit; and
wherein the CCD camera unit is received in the electrical part chamber in a sealed condition.
