A purpose more of the present utility model is to provide a kind of electric connector, by changeing the shell that covers with pin, make electric connector have heavily the convenience of going up, keeping in repair even reclaim.

For achieving the above object, the electric connector that the utility model provides, comprise one first shell, one second shell and a terminal base, this terminal base is provided with a plurality of terminals, can conduct the telecommunications signal, and this first shell coats this terminal base and becomes one, this first shell also becomes a docking port in terminal base the place ahead, connector for a butt joint inserts, and plug-in this first shell outside of being fixed in of this second shell becomes an electric connector; This second shell is provided with a plurality of pins, makes electric connector can be fixedly welded on printed circuit board (PCB).

Wherein this electric connector further respectively is provided with a location division in the two side of first shell, and respectively is provided with a fastener in the two side of second shell, and these fasteners can be sticked in these corresponding location divisions, makes second shell can be fixed in first shell outside.

Wherein the perforate of first side wall of outer shell is located at at least one in this location division.

Wherein the groove in first side wall of outer shell outside is located at at least one in this location division.

Wherein this fastener is located at the door bolt sheet that second side wall of outer shell inwardly protrudes out at least one.

Wherein this fastener is located at the projection of the second side wall of outer shell inboard at least one.

Wherein this first shell upper wall is provided with a plurality of outstanding shell fragments downwards.

Wherein this first shell lower wall is provided with a plurality of shell fragments that project upwards.

Wherein this first shell extends upward a stop tab perpendicular to upper wall at this docking port place.

Wherein this stop tab is provided with a fixing hole.

Embodiment

For understanding spirit of the present utility model and technical characterictic more, after act following examples and conjunction with figs. are specified in.

See also Fig. 2 to Fig. 4, this connector comprises one first shell 1 among the utility model first embodiment, one second shell 2 and a terminal base 3, this terminal base 3 is provided with a plurality of terminals 31, can conduct the telecommunications signal, this first shell 1 coats this terminal base 3, become a docking port 11 in terminal base 3 the place aheads, connector for a butt joint inserts, the two side of first shell 11 respectively is provided with a location division 12, this second shell 2 is sheet thin plates, both sides are bent into side plate 22 separately downwards, on this biside plate 22, respectively be provided with a fastener 23 corresponding to these location divisions 12, these fasteners 23 can be sticked in these location divisions 12, make this second shell 2 can be fixed in this first shell, 1 outside, these second shell, 2 side plates 22 extensions downwards are provided with a plurality of pins 24, make connector can be fixedly welded on printed circuit board (PCB), and the length of this pin 24 can be set according to user demand and make.
