When in the host cavity of described banjo intercalation at socket, this existing socket lacks corresponding catch mechanism and holds and fix this banjo, thereby make this banjo firmly intercalation in described socket, and then make and can not reach reliably electrically contact between the conducting terminal of the conducting terminal of plug and socket.

The utility model content

The utility model purpose provides a kind of board to board connector, and firmly the intercalation banjo guarantees the excellent electrical property contact.

For achieving the above object, the board to board connector that the utility model provides comprises insulating body and a plurality of conducting terminal.Insulating body has base plate, the relative both sides of base plate are convex stretches out a pair of first side wall, the base plate opposite end is convex to stretch out a pair of second side wall, described base plate protrudes upward a nesting part from the middle part, form a host cavity between this nesting part and described first, second side wall, the relative both sides of insulating body offer a plurality of terminal grooves respectively and are used to accommodate corresponding conducting terminal, and the inwall of described side wall is convexly equipped with and forms the holding section of stretching into described host cavity.

As improvement of the present utility model, described first side wall has an inner surface, and this inner surface caves in a little respectively at two ends and forms a concave surface, and the concave surface of each first side wall end is convexly equipped with respectively and forms the described holding section of separation in described nesting part both sides.

As improvement of the present utility model, described holding section is included in substrate that vertically extends on the concave surface and the convex extension part that is communicated in this substrate top, this convex extension part has an outer surface, this outer surface is a smooth surface, and upwards level and smooth again depression terminates in described concave surface top after the substrate top upwards smoothly protrudes out.

As mentioned above, when the grafting mutually nested of the utility model board to board connector with corresponding plug, inwardly replace the sidewall of this plug by the convex extension part of holding section, and the balance support effect that substrate played of holding section, make this plug firmly intercalation at the board to board connector of this creation, to keep the excellent electrical property contact.

Embodiment

By describing technology contents of the present utility model, structural feature in detail, being reached purpose and effect, below exemplify specific embodiment and cooperate the graphic detailed explanation of giving.

See also Fig. 1 and Fig. 2, the utility model board to board connector 100 comprise insulating body 10 and be housed in a plurality of conducting terminals 20 in this insulating body 10 and four help weld tabs 30.

Please in conjunction with Fig. 3, insulating body 10 body that roughly is rectangle has flat base plate 11, and base plate 11 relative both sides are convex stretches out a pair of first side wall 12 and extend along the longitudinally of base plate 11, and base plate 11 also stretches out a pair of second side wall 13 in opposite end is convex.Base plate 11 middle parts protrude upward the rectangle nesting part 14 of a longitudinal extension, this nesting part 14 is all separated by a distance with described first side wall 12 and second side wall 13, thereby makes this nesting

part

14 and 12,13 host cavities 15 that form a rectangular ring of first, second side wall.Insulating body 10 relative both sides offer a plurality of terminal grooves of equidistantly arranging along longitudinally 17 respectively, are used to accommodate corresponding conducting terminal 20.Each first side wall, 12 opposite end offer respectively run through up and down help weld groove 16, describedly help weld tabs 30 to be retained on correspondingly to help in the weld groove 16 its lower ends and be welded on the external circuit board (not shown), thereby this board to board connector 100 is fixed on this circuit board.

Please continue to consult Fig. 3 and in conjunction with Fig. 4, each first side wall 12 has an inner surface 18, this inner surface 18 caves in a little respectively at two ends and forms a concave surface 181, and this is to concave surface 181 and the 18 common inwalls that constitute first side walls of the inner surface between it.The concave surface 181 at each first side wall, 12 two ends is convexly equipped with respectively to form and divides the holding section 182 that occupy described nesting part 14 both sides and stretch into described host cavity 15.This holding section 182 is included in substrate 183 that vertically extends on the concave surface 181 and the convex extension part 184 that is communicated in these substrate 183 tops, this convex extension part 184 has an outer surface 185, this outer surface 185 is a smooth surface, and upwards level and smooth again depression terminates in described concave surface 181 tops after substrate 183 tops upwards smoothly protrude out.

When the utility model board to board connector 100 during with the mutually nested grafting of corresponding plug (not shown), the host cavity 15 of described plug being aimed at insulating body 10 inserts, and the convex extension part 184 of the holding section 182 that the sidewall of this plug is convexly equipped with along the inboard of described first side wall 12 embeds in the described host cavity 15 gradually.Inwardly replace the sidewall of this plug by this convex extension part 184, and the balance support effect played of the substrate 183 of holding section 182, make this plug firmly intercalation guaranteed the excellent electrical property contact at the utility model board to board connector 100.

In addition, above-mentioned execution mode only is the better embodiment of the utility model board to board connector 100, should not constitute restriction of the present utility model.In the specific implementation, the utility model board to board connector 100 can also have other execution mode, for example the holding section 182 that is convexly equipped with of first side wall 12 is not limited to be located in the manner described above the inwall both sides of this first side wall 12, can also adopt other different structure, be located at first side wall, 12 other positions, also can be located at or be located at simultaneously the inwall of second side wall 13.
