Description
Technical field
The present invention relates to the accessory technical field of electronic component, especially relate to a kind of capacitor insulation terminal cap.
Background technology
Conventionally, the formation of capacitor insulation terminal cap is: on the upper surface of lid prepared by insulating material, be fixed with fast connecting terminal by rivet, and this rivet is fixed on bonding pad on the lower surface of this lid simultaneously, and the internal power cord of this capacitor is electrically connected this bonding pad by the mode of welding.This terminal cap has following defect: 1, parts used are more, consistency is poor, is easy to cause larger contact resistance (how in 2m Ω left and right); 2, the bonding area of bonding pad and internal power cord is less, is easy to come off or rosin joint; 3, when bonding pad is riveted, easily cause spacing larger, cause the creepage distance of power supply larger.
Summary of the invention
The object of this invention is to provide a kind of capacitor insulation terminal cap, it have simple in structure, contact resistance is less, internal power cord difficult drop-off, the stable feature of creepage distance.
The technical solution adopted in the present invention is: capacitor insulation terminal cap, comprise lid prepared by insulating material and the internal power cord of capacitor, described capacitor insulation terminal cap also comprises fast connecting terminal, this fast connecting terminal comprises and is riser and the transverse slat that " L " font links together, on this riser, there is upper connecting hole, this transverse slat is provided with lower connecting hole, the edge of this lower connecting hole extends to form connecting cylinder downwards, simultaneously, the installing hole that this lid is provided with and this connecting cylinder matches, this connecting cylinder is stuck in this installing hole by the mode of punching press, and, the metal-cored mode by welding of this internal power cord is fixed in this connecting cylinder, and welding material used is full of in this connecting cylinder.
Described connecting cylinder is thin dolioform in the middle of forming after punching press.
The advantage that the present invention has is: simple in structure, contact resistance is little, internal power cord difficult drop-off, creepage distance stable.The parts that capacitor insulation terminal cap of the present invention adopts are less, adopt the direct connection of line and fast connecting terminal, thus simple in structure, non-contact resistance; Welding material surrounds the metal-cored of line completely, thereby contact area is large, difficult drop-off and rosin joint; Between bonding pad, spacing is fixed, thereby the creepage distance of power supply is comparatively fixing.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is that embodiments of the invention are looked cutaway view (not containing welding material) the master of decomposing state;
Fig. 2 is that the master after lid of the present invention is connected with fast connecting terminal looks cutaway view;
Fig. 3 is that the master of embodiments of the invention looks cutaway view.
In figure: 10, lid; 20, internal power cord; 30, fast connecting terminal, 31, riser, 311, upper connecting hole, 32, transverse slat, 321, lower connecting hole, 322, connecting cylinder.
Embodiment
Embodiment, is shown in shown in Fig. 1 to Fig. 3: capacitor insulation terminal cap, comprises lid 10 prepared by insulating material and the internal power cord 20 of capacitor.Obviously, this internal power cord 20 must have metal-cored.Further say, this capacitor insulation terminal cap also comprises fast connecting terminal 30.This fast connecting terminal 30 comprises and is riser 31 and the transverse slat 32 that " L " font links together., this fast connecting terminal 30 can be to form after 90 ° of bendings of sheet metal.On this riser 31, have upper connecting hole 311, this transverse slat 32 is provided with lower connecting hole 321, and the edge of this lower connecting hole 321 extends to form connecting cylinder 322 downwards.The formation of this lower connecting hole 321 can be to form by the mode of punching press, and in the process of punching press, makes the edge of this lower connecting hole 321 form this connecting cylinder 322 to downward-extension.Meanwhile, the installing hole 11 that this lid 10 is provided with and this connecting cylinder 322 matches., in this this installing hole 11 of connecting cylinder 322 reeve from top to bottom.This connecting cylinder 322 is stuck in this installing hole 11 by the mode of punching press.That is, after treating that this connecting cylinder 322 inserts in this installing hole 11, take the mode of punching press, the lower limb of this connecting cylinder 322 is swelled slightly, then make this connecting cylinder 322 be stuck in this installing hole 11.Obviously, the diameter of this installing hole 11 preferably equals the external diameter of this connecting cylinder 322, thereby the two can keep contact relation comparatively closely before punching press.And the metal-cored mode by welding such as solderings of this internal power cord 20 is fixed in this connecting cylinder 322, and welding material used is full of in this connecting cylinder 322.Like this, prepare this terminal cap by less parts, make its structure comparatively simple, and there is no contact resistance.And the connection area of its internal power cord 20 and fast connecting terminal 30 is large, difficult drop-off and rosin joint; And the creepage distance of power supply is comparatively fixing.
Further say, this connecting cylinder 322 is thin dolioform in the middle of forming after punching press.Like this, be convenient to the filling of welding material, and welding material is thin dolioform in the middle of forming afterwards in welding, has then not only strengthened contact area, and very firm.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
