Abstract
The utility model relates to an electric connector which can be arranged on a base board, comprising an insulation casing, a plurality of terminals and a fixing device. The insulation casing is provided with at least one installation surface which can be arranged toward the base board; a plurality of terminals are contained inside the insulation casing. The high density electric connector is characterized in that the high density electric connector also comprises an obstructing device; the obstructing device is provided with a cylinder and a groove, wherein, the cylinder extends from the installation surface; the groove is arranged in the central position of the cylinder; the fixing device is contained inside the groove of the obstructing device, wherein, the cylinder of the obstructing device and the fixing device can be inserted into the fixing hole of the base board together.
Description
The utility model relates to a kind of electric connector, particularly relates to having baffling device, can prevent the electric connector that scolding tin or scaling powder adhere to.
The electric connector of prior art is by fixture electric connector to be fixed on the substrate.This electric connector is to make with the metal material punching press mostly, crossing in order to be installed up to substrate in the process of tin stove, and the situation that floating appears in regular meeting, it is bad that electric connector is fixed after welding.In addition, the tin liquor of molten condition even can be via the fixing hole of substrate is inhaled to the electric connector direction is contrary along fixture, and is caused excessive tin, makes scolding tin adhere to terminal and is short-circuited.And, can pass through flux bath at circuit board by the tin stokehold, the scaling powder in the groove can adhere to a side of circuit board via the stirring of gases at high pressure, still, scaling powder also can adhere in the termination contact district to the absorption of electric connector direction along fixture, causes terminal to be difficult for the phenomenon of conducting.
For addressing the above problem, generally be to deepen to strengthen the interference region of fixture and circuit board fixing hole, to prevent that the situation that electric connector floats from taking place.In addition, with the bending of the contact jaw of terminal or fixture and circuit board or stamp little breach, in order to stop tin liquor the situation of adhesion takes place along contrary suction the in gap of fixture or terminal and fixing hole.Then washing oven dry again with a large amount of clear water for the problem of scaling powder adhesion terminal solves.Yet, strengthen the interference region of deepening fixture and can cause the installing force of electric connector on substrate to increase, be easy to cause destruction, and the difficulty of manufacturing is increased circuit board; With the way of terminal bending, then will change the circuit arrangement on the substrate with anti-overflow tin; Terminal is stamped small gap, then increase technologic difficulty, and produce simultaneously that stress is concentrated and problem such as coating accumulation; To remove scaling powder, certainly will cause sizable pollution with a large amount of clear water irrigation circuit plates, what add when oven dry electric power expends and the increase of processing step the requirement that does not meet environmental protection and save cost.
From the above, prior art does not propose suitable solution with regard to foregoing problems, or still has the difficulty of its enforcement and part to be overcome is arranged.
The purpose of this utility model is to provide a kind of electric connector with baffling device, is soldered in the process of substrate at electric connector, can prevent that electric connector from floating and scolding tin or scaling powder adhere on the terminal.
For achieving the above object, the utility model provides a kind of electric connector that is installed on the substrate, and it comprises: an insulation shell, and having one at least can be towards the installed surface of substrate installing; A plurality of terminals that are accommodated in the insulation shell; And fixture, it also comprises a baffling device, have a cylinder and a groove on it, wherein said cylinder extends from described installed surface, described groove is arranged on described cylindrical central part, described fixture is accommodated in the groove of described baffling device, and wherein, the cylinder of described baffling device can plug in the fixing hole of substrate with described fixture.
The advantage of electric connector of the present utility model is, because the cylinder of baffling device can insert in the fixing hole of substrate with fixture fixing hole is stopped up, thus can prevent scolding tin or scaling powder along fixture towards the electric connector direction contrary suction the and cause scolding tin, scaling powder to adhere to the situation that terminal or electric connector float to take place.
Below in conjunction with accompanying drawing in detail preferred embodiment of the present utility model is described in detail.In the accompanying drawing:
Fig. 1 is the stereogram of electric connector of the present utility model, wherein shows the bottom of electric connector, the separated attitude of the insulation shell of fixture and electric connector;
Fig. 2 is installed up to the front view of substrate, the wherein structure of display part electric connector and substrate for the utility model electric connector;
Fig. 3 is installed up to the end view of substrate for the utility model electric connector;
Fig. 4 is installed up to the bottom view of substrate for the utility model electric connector, wherein the also structure of display part electric connector and substrate.
See also Fig. 1,2 and 3, electric connector 10 of the present utility model mainly comprises insulation shell 12, a plurality of terminal 14, baffling device 16 and fixture 18.This insulation shell 12 has an installed surface 122, and electric connector 10 is installed in the face of substrate 20 with this installed surface 122.A plurality of terminals 14 are installed in the insulation shell 12, and give prominence to and be installed on substrate 20 from installed surface 122 to the outside of electric connector 10.This baffling device 16 comprises turriform portion 162 and cylinder 166 two parts, wherein, 12 outside extensions are provided with from installed surface 122 towards insulation shell in turriform portion 162, has coverage rate 164 in turriform portion 162 with respect to the other end of installed surface 122, please be simultaneously with reference to Fig. 4, the Zone Full of the fixing hole 22 of substrate 20 can be contained in the zone of this coverage rate 164,12 outside extensions are provided with cylinder 166 from coverage rate 164 towards insulation shell, the external diameter of this cylinder 166 is slightly less than the external diameter of substrate 20 fixing holes 22, its central part is provided with elongated slot 168, and fixture 18 can be installed in the elongated slot 168.
When electric connector 10 is mounted to substrate 20, terminal 14 inserts in the terminal jacks 24 of substrate relatively, fixture 18 is inserted in the fixing hole 22 of substrate 20 with cylinder 166, fixture 18 is fastened in the periphery of fixing hole 22, fixing hole 22 is blocked by cylinder 166 with the gap of fixture 18, turriform portion 162 is with insulation shell 12 bed hedgehoppings, coverage rate 164 is smooth in the surface of substrate 20, inhale along fixture 18 is contrary to block fusion scolding tin or scaling powder, thereby prevent to overflow tin and prevent that scaling powder from adhering to terminal.In addition, cylinder 166 inserts in the fixing hole 22 of substrate 20 tightly, and can strengthen the fixed effect of fixture 18, takes place with the situation of avoiding electric connector to float.
