Description

The electric connector location structure of improvement

Technical field

The utility model relates to electric connector field, especially the electric connector location structure for improveing.

Background technology

The computer technology industry is flourish now, the speed of its research and development technology is at a tremendous pace, the compact boundary and all computers and peripheral product thereof are marched toward invariably, the transmission of its power supply and signal utilized electric connector to reach transmission and the function of changing when product used, thereby electric connector is for the also increase day by day of importance of product, manufacturing enterprise the location structure of electric connector partly with its production process on design and research and development, reach and produce solder overflow and the purpose of simplifying processing procedure when preventing to weld; When holding element, makes on the design button in the mode of lathe turning, stereo appearance figure when seeing also the use shown in the 5th figure, be to have button to hold element B at the pedestal A1 of insulating base frame A one side build-in, the holder B1 opposite side that its button is held element B has extended holding part B2, and is provided with a groove B21 and extends on the surface of holder A1 in the central part of holding part B2; Yet above-mentioned this design still has following a little disappearance:

1, to hold the production method of element be to carry out one turning moulding with lathe to its button, its manufacturing process is for after being shaped to the holding part structure and making with rectangular metal derby front end turning, be lathed the structure that type is a holder at its rear, and block in the turning of holder rear end, carry out next processing procedure action by remaining metal derby again, need expend the considerable time, make the low and prolongation in man-hour of production efficiency.

2, its holder strengthened its volume in when design, and this purpose is its bed hedgehopping can be touched and remains on the insulating base frame to prevent that tin liquor is stained with when holder being embedded the pedestal of insulating base frame, but has caused manufactured materials and cost waste simultaneously.

3, the groove of its holding part is to cut and extend on the surface of holder in the turning mode, is cut the restriction of lathe tool specification, so that the recess width that is cut out also can't be meticulous, is easy to generate the bad phenomenon of the tin that overflows when also making welding.

Other has a kind of design is that holder and holding part are separated making, see also shown in the 6th figure, stereo appearance figure when being another design use, be to have button to hold element D at the pedestal C1 of insulating base frame C one side build-in, its button is held element D and is included holder D1 and holding part D2, holding part D2 is at a base D21 and extends the retaining sheet D22 that is launched into two above it, behind the base D21 of holding part D2 and the mutual buckle of holder D1, retaining sheet D22 is bent into the structure of parallel upright with manual type, and between holding part D22 and holder D1, is provided with a clearance D 3; Yet the design of above-mentioned use still has following disappearance:

1, this holding part must be with two holding pieces with the manual type bending forming with after making of the integrated punching mode, and this mode need expend considerable manpower and activity duration, and fracture is easily caused in its bending place.

2, tangible gap is left in the junction of its holding part and holder, and causes the bad phenomenon of the tin that overflows can cause welding the time easily.

Therefore, above-mentioned existing design can not reach required substantially in the processing procedure, the tin that promptly prevents to overflow, saves cost and the purpose that increases output.

The utility model content

For overcoming the deficiencies in the prior art, the utility model provides a kind of tin that prevents to overflow to take place, and the electric connector location structure of the improvement of escapable cost and increase output.

The utility model is for achieving the above object, and adopt following proposal: a kind of electric connector location structure of improvement is provided with pedestal on insulating base frame, one side of pedestal is provided with the docking section, connect and be equipped with the complex conduction terminal in the portion, the pedestal both sides are respectively equipped with open-work, are positioned with button in the open-work and hold element; It is characterized in that: this button is held element and is comprised holder and holding part, holder is provided with fixed leg in a side of base, the both sides of base are provided with fitting portion, the fixed leg inner edge of holder is provided with plural screw thread, holding part is provided with buckling parts in a side of base portion, is extended with pin away from the opposite side of buckling parts.

Wherein, this complex conduction terminal that is arranged in the docking section of insulating base frame is the docking section that can protrude in insulating base frame side outer rim in addition.

Wherein, the pin of this holding part is and is oppositely arranged, and is provided with groove between two pins.

Wherein, holding part is extended with the elastic arm with grab in the both sides of base portion, and the fitting portion of holder is provided with latch.

The utlity model has following beneficial effect: after the buckling parts of holding part is inserted in the fitting portion of holder bottom, the gap of its junction is very tiny, and then the pin of holding part can be welded in the time of being located at circuit board, can prevent effectively that solder overflow from producing, and the structure of holding part belongs to compact type, available die sinking impact style makes the output multiplication, and then can reach the purpose of simplifying processing procedure.
