This protective gear 101 is fixed on of conductive contact 111 of airtight terminal 110 of the sealing shell that is arranged at sealed electrical compressor.Weld fixedly filling-in bit terminal 112 on the conductive contact 111 of this airtight terminal, be inserted in this filling-in bit terminal and the conductive contact by the splicing ear 104 with protective gear, protective gear 101 is fixed with respect to airtight terminal 110.Like this; a side the conducting terminal joint 102B that is fixed in the protector 102 of the protective gear 101 in the seal container of motor compressor is connected with the power supply of seal container outside by airtight terminal 110, and the opposing party's conducting terminal joint 102C then is connected with the lead 113 that links to each other with the motor winding by splicing ear 105.In this embodiment, as shown in Figure 17, the sleeve terminal 114 of lead 113 front ends inserts splicing ear 105 and connects.
For the motor compressor protective gear 101 that is installed on like this on the sealed electrical compressor,, therefore can promptly carry out heat exchange with refrigeration agent because the canister 102A of protector 102 directly is configured among the stream of refrigeration agent.Among the running of motor compressor; flow in the circuit of its operating current in protector and make inner body generate heat; but because generally this heating value keeps state of equilibrium substantially with the heat that is absorbed by refrigeration agent, thereby hot servoelement can not reach the operating temperature of contact mechanism.If since certain abnormal conditions cause the rising of refrigerant temperature or refrigeration agent reduce cause dispelling the heat descend or protector in feeding excess current when making that temperature surpasses the operating temperature of hot servoelement; protector cuts off the power supply by opening its contact mechanism, thereby prevents the overheated destruction that causes of motor compressor and burn out.
For existing motor compressor protective gear 101; splicing ear 104 and 105 is with respect to support 103 predetermined fixed; the conducting terminal joint 102B and the 102C of difference welding protection device 102 on above-mentioned splicing ear, thus protector 102 is remained secured to support 103.
But, in this case, because splicing ear 104 is different with 105 shape, and a side splicing ear 105 embeds in advance and forms in support 103, for example want to change the occasion of using left and right sides terminal, when wanting to change the shape of terminal or the occasion of combination etc., do not just win the shape that changes terminal, even have to change new support 103 with matching.Therefore, the kind of support increases owing to the kind of terminal or the difference of combination, has the problem that lacks versatility.
