Description
Technical field
The utility model relates to a kind of switch, relates in particular to the switch that a kind of pin has waterproof effect.
Background technology
The injury of electronic component maximum is that the threat from water can cause the electronic component risk of short-circuits; because the all-pervasive characteristic of water; even having the electronic component of housing protection also can damage because of the infiltration of water; if the easier situation of cocking off that causes of the influence that provides the switch of current lead-through function to be subjected to water, its influence be we can say quite huge.
At this problem, many switch designs provide waterproofing design, its body interior that is the structural improvement of No. 496567 described a kind of water proof switch of TaiWan, China utility model patent for example, its main water-proof function disposes waterproof washer and enters the internal circuit of this water proof switch to stop water.
The structural design that the water proof switch of other relevant Patent publish is also arranged can be and utilize the packing ring that is arranged on switch main body inside to reach good waterproof effect with reference to TaiWan, China utility model patent No. 551595, No. 495089 or the like.Yet above-mentioned all kinds of patents all is only limited to the water-proof function of body interior, and pin and electric wire junction also are important links, whether can reach complete good waterproof effect aside from the above-mentioned mode of waterproof washer of utilizing, if the same switch that can allow with the short circuit of electric wire junction of water proof switch pin damages, cause unpredictable loss.The known practice is to use core place that heat-shrink tube exposes pin and electric wire to be coated with to reach insulation effect, but involution pin and electric wire, especially pin and main body junction fully by this way more can't reach isolated in the mode of heat-shrink tube.
In addition, because the electric wire core also is complained by the user with the effect that is electrically connected of pin, its main cause is that majority was fixing again with welding manner after core was fixedly installed on pin, and the annexation of pin and core can't be therefore and firmly, will produced fracture with the pin connecting place or get loose if core pulls, rotated, and then produce the situation of loose contact.
Please refer to Fig. 1, it is the schematic diagram of prior art, as shown in the figure: for avoiding above-mentioned situation, prior art has disclosed a kind of water proof structure of switch pin, and its switch main body 10 is provided with respectively at pin 12 places and buries hole 11 underground, and the connection of pin 12 and electric wire is then in burying hole 11 underground, at pin 12 with after electric wire rod 20 is connected, bury hole 11 underground and fill with insulator 30 again, thereby electric wire rod 20 is imbedded with pin 12, can reach the effect of waterproof insulation.
In addition, please refer to Fig. 2, it is the schematic diagram of another prior art, as shown in the figure: its water proof structure is the outer end that earlier a housing 40 is fixedly installed on the pin 12 of switch main body 10, wherein 20 in pin 12 and the electric wire rod that is connected are covered by described housing 40, electric wire 20 stretches out at the opening part 41 of housing 40 and switch main body 10 formation, utilizes the encapsulating mode that insulator is inserted in the housing 40 by described opening part 41 again, obtains sealing the junction of pin 12 and electric wire rod 20 thus.
Though above-mentioned two kinds of prior aries can provide the retention effect of firm electric wire rod 20 and the water-proof sealing effect of electric wire rod 20 of complete coating and pin 12 joints, but still there is the glue problem of overflowing, and carry out the mode of gluing by hand, efficient is low and quality is unstable, does not meet cost benefit.
The utility model content
Main purpose of the present utility model is to solve the defective that exists in the above-mentioned prior art, a kind of switch pin water proof structure is provided, it is the insulative water-proof material that pin that exposes at switch and the joint of the electric wire rod that is connected with pin are provided with the described joint of coating, make the joint of this pin and electric wire rod reach the purpose of isolating by the insulative water-proof material with water, wherein the insulative water-proof material also can the holding electrical wire rod, reduces the chance that electric wire rod separates with pin.
Another purpose of the present utility model is to provide the manufacture method of manufacturing according to switch pin water proof structure of the present utility model, this manufacture method is that switch is put into the mould location and formed the material feeding space in the junction of pin and electric wire rod, also provide the auxiliary clamp of holding electrical wire rod that electric wire rod is fixed in the mould, in this material feeding space, inject the water proof structure of insulative water-proof forming materials and switch formation one again with shoot mode, this manufacture method fast and quality fix, can be so that use and make processing automatically.
To sum up, can reach the purpose of isolating, reduce the chance that the electrical equipment wire rod separates with pin with water according to the water proof structure of switch pin of the present utility model, with and manufacture method fast and quality fix, be convenient to use automatic manufacturing processing.
