Abstract

A power connector may comprise a first connecting member and a second connecting member. The first connecting member has a plurality of first terminals, and a connecting base formed at an end of the second connecting member comprises a plurality of L-shaped slots thereon, and each of the L-shaped slots has a second terminal secured therein. When the first terminals and the second terminals are connected, the first connecting member and the second connecting member are electrically connected. The other end of the second connecting member has a first base which comprises a connecting surface and an assembling surface, and a second frame protruding from the assembling surface has a first housing therein. A cover is disposed in the first housing, and an outer periphery of the cover has a first packing groove filled with a hot-melt adhesive layer to achieve sealing effect.

Claims

1. A power connector comprising,

a first connecting member having a plurality of first terminals, and

a second connecting member comprising a connecting base at an end thereof, and the connecting base having a plurality of L-shaped slots thereon, and each of the L-shaped slots comprising a second terminal secured therein;

when the first terminals and the second terminals connected, the first connecting member and the second connecting member electrically connected;

the other end of the second connecting member having a first base, and the first base comprising a connecting surface which is faced to the connecting base and an assembling surface which is located at an opposed side of the connecting surface;

a second frame, which protrudes from the assembling surface, comprising a first housing therein which is communicated with the L-shaped slots, and each of two lateral edges of the second frame having an engaging slot at corresponding positions;

each of the second terminals comprising a pin protruding toward the first housing, and the pin configured to couple with the second frame and protrude from the first base;

the second connecting member having a cover disposed in the first housing, and each of two ends of the cover comprising an engaging block which is adapted to engage with the engaging slot so as to enable the pin to be clamped between the second frame and the cover;

an outer periphery of the cover having a first packing groove, and a hot-melt adhesive layer configured to pave on the first packing groove to achieve sealing effect on the first packing groove, and the hot-melt adhesive layer adapted to seal around the pin.

2. The power connector of claim 1, wherein a second packing groove is formed on an inner periphery of the second frame of the second connecting member, and the second packing groove is adapted to collaborate with the first packing groove to circle around the pin, and the hot-melt adhesive layer is adapted to be filled around the pin with the thickness same as the depth of the first packing groove and the second packing groove.

3. The power connector of claim 1, wherein the second connecting member has a plurality of locating slots, and each of the locating slots is located between two adjacent pins;

a plurality of abutting blocks are formed at an edge of the cover;

the first packing groove is formed across an peripheral edge of the abutting blocks, and the abutting blocks are accommodated in the locating slots so as to secured the single pin between two adjacent abutting blocks, and the pins are configured to protrude from a surface of the cover which is paved with the hot-melt adhesive layer.

4. The power connector of claim 3, wherein the connecting base has a plurality of partitions, and each of the partitions is located between two adjacent L-shaped slots, and a bottom portion is extended from the partition to accommodate in the first housing;

a concaved second housing is formed on the other surface of the cover which is faced to the first housing, and the second housing is extended to the abutting blocks;

a waterproof second gasket is installed at the second housing, and the second gasket is directly abutted against the bottom portions of the partitions, and the second gasket is configured to surround outer peripheries of the pins.

5. The power connector of claim 1, wherein the first base has two block bodies protruding from the assembling surface, and the two block bodies are connected to the second frame to reinforce the structural strength of the second frame;

the second frame is processed to form the two engaging slots without penetrating through the second frame.

6. The power connector of claim 5, wherein the first base comprises two inner threaded bushings, and each of the inner threaded bushings has an end extending to the connecting surface of the first base, and the other end of the inner threaded bushing is configured to extend to an interior of the block body so as to enable the block body to enhance the structural strengths between the first base and the inner threaded bushing.

7. The power connector of claim 1, wherein a sealing unit connected to the first connecting member comprises a plurality of through holes which are configured to be respectively passed through by the first terminals;

a side piece vertical protrudes from an edge of the sealing unit to form an L-shape, and the sealing unit collaborated with the side piece is abutted against the L-shaped slot when the first terminal is connected to the second terminal.

8. The power connector of claim 1, wherein the second connecting member has a first gasket disposed on the connecting base, and the first gasket abutted against the connecting surface is configured to achieve the waterproof effect when the first base of the second connecting member is connected to an external component, and the first gasket is abutted against between the first base and the external component.

9. The power connector of claim 8, wherein an annular groove is formed on the connecting surface of the first base, and a third frame is connected to an inner edge of the first gasket;

the third frame is wider than the first gasket so as to axially protrude from two lateral sides of the first gasket to form a first protruding portion and a second protruding portion, wherein the first protruding portion faced to the second connecting member is configured to insert into the annular groove, and a second protruding portion protrudes toward the first connecting member, and the second protruding portion is abutted when the second connecting member is connected to an external part so as to enable the first protruding portion to abut against the annular groove.

10. The power connector of claim 1, wherein each of the second terminals has a first frame which enables the second terminal to be secured in the L-shaped slot, and two parallel clamping pieces are configured to extend from the first frame toward the second frame, and each of the clamping pieces has a offset bending thereon;

an end of the clamping piece connected to the first frame is located close to an opening of the L-shaped slot, and the other end of the clamping piece is located close to the first housing so as to enable the two clamping pieces to tightly clamp a lower portion of the first terminal.
