Abstract
Description
- The present invention relates to an electrical connector assembly and, more particularly, to an electrical connector assembly that is useful for waterproof applications.
- Various conventional waterproof connectors have been proposed. Many of these connectors have complicated structures that have a tendency to decrease the operability of the connectors, as a result of the waterproofing effect. Additionally, with waterproof connectors waterproofing cannot usually be provided to a member connected to the connector. The present device has been proposed in consideration of this situation, and it is an object to provide a waterproof connector as a connector assembly having a simple structure and good operability so as to eliminate conventional drawbacks.
- It is a primary object of the invention to provide an improved waterproof connector assembly.
- In accordance with a preferred form of the invention, a waterproof connector assembly comprises a board having opposite surfaces and including a plurality of conductors thereon, the conductors being exposed to one of the surfaces. A housing supports a plurality of contacts in electrical engagement with the exposed conductors. A compressible member, supported by the housing, circumscribes the contacts and is disposed between the board and the housing. A holding member supported by the housing includes a resilient portion for resiliently urging the board toward the housing and thereby causing electrical engagement between the conductors and the contacts and compressing the compressible member between the housing and the board to provide a waterproof seal around the engaged conductors and contacts.
- Figures 1A, 1B and 1C are perspective views showing the respective elements of one embodiment of the present connector assembly.
- Figure 2 is a longitudinal sectional view of the connector assembly of Figure 1.
- Figure 3 is a transverse cross-sectional view of the assembly of the connector assembly of Figure 1.
- Referring now to Figures 1A through 1C, a connector of the present device is shown with a member connected thereto, such as a printed
circuit board 1. Ahousing 2 of the connector includes a plurality ofcontacts 21 at suitably spaced pitches. Thehousing 2 has a board insertion recessedportion 23 for inserting theboard 1.Distal end portions 21a of the contacts are exposed in theboard insertion portion 23. In a connecting state, described hereinafter, thecontacts 21 are in contact with conductors portions ofconductor parts 11 of the printedcircuit board 1, respectively. Opposite end portions of the contacts constitute dependinglegs 21b to be connected to another printed circuit board 4. - A
packing member 22, such as an elastomeric ring, is disposed in thesubstrate insertion portion 23 of the housing so as to surround the plurality of contacts, as shown in Fig. 1C. - The printed
circuit board 1 connected to thehousing 2 includes theconductor parts 11 which are to be electrically connected to electric components mounted on the board or other electric components through the board. The surfaces of theconductor parts 11 are coated with a suitable waterproof film or, alternatively, a waterproof insulatinglayer 12 is formed thereon. Anelongated window 13 is formed through the insulating layer portion which is brought into contact with theend portions 21a of thecontacts 21 in the housing. The edge of thewindow 13 is located inside the edge of theboard 1. The engagement areas between thecontacts 21 and theboard 1 are waterproofed by pressing thepacking member 22 on the edge of the window so as to prevent water from entrance. -
Reference numeral 3 in Fig. 1A denotes a cap member for holding and pressing the printedcircuit board 1 on thecontacts 21 in thehousing 2. In the illustrated embodiment, the ends of thecap member 3 all have dependingflanges 32 withopenings 33 therethrough which are engaged withlatches 24 arranged at the end faces of thehousing 2. In the present device, the latching means is not limited to the specific latch shown. - To cause the
cap member 3 to press theboard 1 against thehousing 2, a spring effect is provided in thecap member 3. In the illustrated embodiment,spring members 31 are disposed in thecap member 3. However, other spring effects may also be provided to the contacts. - Figs. 2 and 3 show states wherein the connector is about to be connected to the printed
circuit board 1. In the connector state, the contact portions between theconductors parts 11 of the board and thecontacts 21 are waterproofed by the peripheral portion of thewindow 13 surrounding the contact portions and thepacking member 22 so as to prevent waterdrops from entering the contact portions. - The connector assembly as the present device is provided to have good waterproof properties that result when the board is inserted in the
board insertion portion 23 of thehousing 2 and is held by the holding action of thecap member 3. Therefore, good electrical connections between the board and the contacts can be achieved, and at the same time the contact portions waterproofed. As such, operability is desirably improved relative to a conventional waterproof connector. - Having described the preferred embodiment of the present invention, it should be appreciated the variations may be made thereto without departing from the contemplated scope of the invention. Accordingly, the preferred embodiment is considered as illustrative rather than limiting, the true scope of the invention being set forth in the claims appended hereto.
