Connector with a connection position assurance device
A connector includes a housing having a mating portion matable with a mating connector and a flexible beam with a housing-side catch portion, and a connection position assurance device (CPA) that slides between a first position on the housing and a second position closer to the mating portion than the first position. The CPA in the second position assures that the connector is completely mated with the mating connector. The flexible beam extends in a sliding direction of the CPA and slidably supports the CPA. The housing-side catch portion interferes with the CPA and deflects by interfering with the CPA. The CPA includes a rail that has a device-side catch portion interfering with the housing-side catch portion and that slides while being supported by the flexible beam.
1. A connector, comprising:
a housing having a mating portion matable with a mating connector and a flexible beam with a housing-side catch portion; and
a connection position assurance device that slides between a first position on the housing and a second position closer to the mating portion than the first position and that, by being in the second position, assures that the connector is in a state of being completely mated with the mating connector, the flexible beam extends in a sliding direction of the connector position assurance device and slidably supports the connector position assurance device, the housing-side catch portion interferes with the connector position assurance device and deflects by interfering with the connector position assurance device, the connector position assurance device includes a rail that has a device-side catch portion interfering with the housing-side catch portion and that slides while being supported by the flexible beam.
2. The connector of claim 1 , wherein the flexible beam is one of a pair of flexible beams provided on both sides of the housing in a width direction intersecting the sliding direction.
3. The connector of claim 2 , wherein the rail is one of a pair of rails provided on both sides of the connection position assurance device in the width direction.
4. The connector of claim 1 , wherein the housing-side catch portion is a first housing-side catch portion provided on a first side of the housing and the device-side catch portion is a first device-side catch portion provided on a first side of the connector position assurance device.
5. The connector of claim 4 , wherein the first housing-side catch portion catches the first device-side catch portion when the connector position assurance device is in the first position.
6. The connector of claim 5 , wherein the housing has a second housing-side catch portion provided on a second side of the housing opposite the first side in a width direction intersecting the sliding direction.
7. The connector of claim 6 , wherein the connection position assurance device has a second device-side catch portion on a second side of the connector position assurance device opposite the first side in the width direction.
8. The connector of claim 7 , wherein the second housing-side catch portion catches the second device-side catch portion when the connector position assurance device is in the second position.
9. The connector of claim 1 , further comprising a waterproof seal member.
10. A connector, comprising:
a housing having a mating portion and a flexible beam with a housing-side catch portion; and
a connection position assurance device that slides in a sliding direction between a first position on the housing and a second position closer to the mating portion than the first position, the flexible beam extends in the sliding direction, the connector position assurance device includes a rail that has a device-side catch portion interfering with the housing-side catch portion and that slides while being supported by the flexible beam.
11. The connector of claim 10 , wherein the housing-side catch portion is a first housing-side catch portion, the housing has a second housing-side catch portion on an opposite side of the housing from the first housing-side catch portion.
12. The connector of claim 11 , wherein the device-side catch portion is a first device-side catch portion, the connection position assurance has a second device-side catch portion on an opposite side of the connection position assurance from the first device-side catch portion.
13. The connector of claim 12 , wherein the first housing-side catch portion catches the first device-side catch portion in the first position and the second housing-side catch portion catches the second device-side catch portion in the second position.
14. The connector of claim 10 , wherein the connector has a seal member disposed inside the housing.
15. The connector of claim 14 , wherein the seal member surrounds a cable and forms a waterproof seal between the housing and the cable.
16. The connector of claim 10 , wherein the housing has a lock arm with a front end fixed and a rear end opposite the front end in the sliding direction in a shape of a cantilever beam.
17. The connector of claim 16 , wherein the connection position assurance device has a basal portion with the rail and a beam portion extending from the basal portion.
18. The connector of claim 17 , wherein the beam portion contacts the lock arm in the first position and prevents movement of the connection position assurance device in the sliding direction.
19. The connector of claim 17 , wherein the beam portion engages the lock arm in the second position.
