Description
The utility model relates to a kind of wire rod fixing device, and it comprises one first fixed position, one second fixed position, and one the 3rd fixed position.By fixture of the present utility model, can reach essence fixedly wire rod to be connected with terminal.
The switch (SW) of overwhelming majority power supply unit or socket (Socket) all must combine with wire rod in the use, and this is called wire rod processing (Wire Harness) operation.Have small part then directly terminal to be inserted on the PC plate (being the host housing plate of PC) in addition, this is called board plug type operation (PC Board Mounted).And conception of the present utility model mainly is the shortcoming proposition improvement project at aforesaid wire rod processing operation aspect.
As it is, the processing of all wire rods has only two kinds of operating types, see also Fig. 1, demonstrate the male plug 10 of a welding pattern (Solder Type), be meant bare wire 12 parts of wire rod 11 are inserted in the perforate 14 of terminal 13, utilize scolding tin (Solder) to weld again with fixing bare wire 12.Another kind of operation is quick terminal 15 patterns shown in Fig. 2 (Fasten Terminal Type), this field application mode very widely is that wire rod 11 is gone ahead of the rest fixed processing on a connector 15 (connector), promptly utilize first fixed position 151 among Fig. 3 to fix the insulator 111 of wire rod 11, second fixed position 152 is the fixing electric conductor 112 of wire rod 11 then, again connector 15 is inserted and clamp terminal 13 simultaneously, promptly finish the program of connection.
Yet, the shortcoming of welded type is many, at first be the thermal deformation problem of sticking up the socket 10 among version (Rocker) switch 16 or Fig. 4 as shown in Figure 5: reason is that general provision uses flatiron welding (Iron Soldering) to add man-hour, operating time is 3-0.5 second, can both accomplish but in fact be difficult to take precautions against each operator.In case and weld time is long, the fixed terminal position 17 of switch 16, and the outstanding position 102 of the fixed terminal 13 of the plastic body 101 of socket 10 promptly is easy to overheating deforming, the lighter causes the loss of work,, weight person even can cause short circuit and initiation potential.
Moreover in the process of welding; need to add the polymeric retention aid solder flux; just smell pungent strange taste through regular meeting; electric iron can send the high temperature more than 350 ℃ in addition; and can produce leaded toxic gas; this heavy metal can be accumulated in the human organ, and can't excrete, so health is had extremely bad influence.Though most factory all is provided with the equipment of exhaust duct, but still some factory is in the operation of airtight place, and this has great prestige association to operator health, even if toxic gas can be discharged still more, the result remains loss in air, has caused the pollution of environment.
In addition, international well-known big factory such as Samsung of Intel (Intel) or Korea S etc., all require when the bare wire 12 of welding wire 11, must first spot welding fixing several strand (not shown)s of bare wire 12 own, just penetrate the perforate 14 of terminal 13 then and be turned back on the bare wire 12, be welded in terminal 13 again, though so can guarantee that wire rod 11 can not come off, but increased the burden of manual work, so be the desirable bridging mode of non-genus.
Shortcoming as for quick terminal 15, it at first is the insufficient strength of clamping terminal 13, though do not process the problem that is caused because of bonding wire, but because of operating type is a plug-in type, since available hand inserts, certainly also available hand-lifting goes out, and so low chuck strength military order manufactory all will emit with the consumer just in case the risk that wire rod comes off, or just causes elastic fatigue easily because of long-term use.Moreover, this quick terminal 15 easily produces instant cut-off (Intermittence) phenomenon, because of quick terminal 15 is that the mode of two kinds of metal objects (being quick terminal 15 and the terminal 13 of socket 10) with insertion combined, event is unavoidable to be, might metal and metal can't combine closely, except causing the increase of impedance, and may be to have produced a space (Gap) because of two intermetallic slightly being located away from, in case this space is arranged, behind the then logical upward electric current, will produce the phenomenon of instant cut-off, and make this finished product also become a defective products.
Therefore, how to improve the problem that above-mentioned wire rod and terminal are connected mutually, after the designer carries out research improvement, obtain a kind of wire rod fixing device finally, except the shortcoming of effective solution prior art, also combining two kinds of metals more closely.
Main purpose of the present utility model is to provide a kind of wire rod fixing device, wherein uses a riveted type (Crimp style) connector, comes the firm terminal in conjunction with wire rod and switch or socket.
A purpose more of the present utility model is to provide a kind of wire rod fixing device, wherein utilize have a hollow circuit cylinder to be fixed on the terminal, realize being electrically connected between wire rod and the terminal.
Another purpose of the present utility model is to provide a kind of wire rod fixing device, wherein uses the fixed form of extrusion metal sheet, and wire rod is combined with terminal, has the value of environmental protection.
A time purpose of the present utility model is to provide a kind of wire rod fixing device, wherein fixture be provided with outstanding plate with female terminal on a pair of groove be connected mutually.
A kind of wire rod fixing device provided by the utility model, being used for fixing a wire rod is electrically connected to carry out one with a terminal, on this terminal and have a perforate, it comprises one first fixed position, in order to fix one of this wire rod insulator, one second fixed position, be installed near this first fixed position, in order to fix one of this wire rod electric conductor, and one the 3rd fixed position, be installed near this second fixed position, in order to pass this perforate, and through extruding and this device is fixed on this terminal, to reach being electrically connected of this wire rod and this terminal.
