Description

The waterproof socket connector

Technical field

The utility model relates to a kind of socket connector, relates in particular to a kind of waterproof socket connector.

Background technology

Usually socket connector generally comprises an insulating body, several are fixed at conducting terminal and in the insulating body and are coated on metal shell on the insulating body.Because terminal client is more and more higher to product quality and performance demands, the water-proof function of electronic product is listed in one of important indicator gradually, the most of flexible glue material seal snare that adopts a cross section to be roughly circle of electronic product waterproof technique is located on the socket connector at present, and product shell makes its deformation to sealing ring compression, sealing ring is pasted mutually with socket connector, thereby reach the purpose of water-tight.

Yet, because the variant of sealing circle is very unstable, cause one-sided shift phenomenon easily, therefore be difficult to the classification of waterproof that reaches higher.

The utility model content

The purpose of this utility model is to provide a kind of waterproof socket connector at above-mentioned the deficiencies in the prior art, this waterproof socket connector can prevent that dust and water from entering into connector inside, can reduce the friction between banjo connector and the insulating body again, thereby good contact engaging and separating force is provided.

For achieving the above object, waterproof socket connector provided by the utility model comprise insulating body, coat described insulating body metal shell, several are retained on the conducting terminal in the described insulating body and are installed in and be used to detain the fixed part of holding the banjo connector in the described insulating body.Described insulating body comprise the host cavity that surrounds by roof, three sidewalls and diapire, opening and from the sidewall relative with described opening to Plug Division that host cavity protrudes out.Described fixed part comprises two keepers and a card-bit part.Described metal shell has the accommodation space of the perforation that is surrounded by a top board, a base plate and two side plates, to accommodate described insulating body.Described waterproof socket connector also comprises first metallic interconnect and second metallic interconnect that periphery is stepped, the roof of described insulating body and diapire are respectively equipped with first groove perforation and that be communicated with described host cavity and second groove, the described first groove periphery is also stepped, described first metallic interconnect and described second metallic interconnect are contained in respectively in described first groove and described second groove, and be sealed and matched by the ladder periphery, be respectively equipped with groove in relative two sidewalls of described insulating body.The centre of each described keeper offers a through hole, and described through hole one edge outwards bending is extended with a baffle plate, and sleeve is in the groove of described sidewall respectively for two described keepers, and the side plate of described baffle plate and described metal shell is closely conflicted.The top board of described metal shell and described first metallic interconnect fit tightly, and described card-bit part is fixed on the diapire of described insulating body and fits and hold described second metallic interconnect, and the base plate of described metal shell and described card-bit part fit tightly.

As mentioned above, because the hole on the insulating body of the utility model waterproof socket connector is very little, and the outside of insulating body adopts metal shell to closely cooperate, thereby can prevent effectively that dust and water from entering into connector inside.In addition, because first metallic interconnect is concavo-convex the cooperation with the groove of insulating body, thereby can reduce to cooperate the slit, prevent that steam from entering.Moreover, because the part that contacts with the banjo connector is two metallic interconnects, thereby can reduce the friction between banjo connector and the insulating body, thereby provide good contact engaging and separating force.
