Embodiment
Fig. 1 is the oblique view that the circuit-breaker behind the insulated barriers wall has been installed in the embodiments of the present invention 1, Fig. 2 is the oblique view that the preceding circuit-breaker of insulated barriers wall is installed in the execution mode 1, and Fig. 3 is the vertical view that comprises the part of the splicing ear of circuit-breaker among Fig. 1.The main body 1 of circuit-breaker has not shown internal mechanism in the inside of housing 10, and has and this internal mechanism connection terminals 2.Housing 10 is made of pedestal 10a and lid 10b, and splicing ear 2 is configured in mains side and the load-side of pedestal 10a respectively corresponding to each electrode.Each splicing ear 2 is connected with not shown bonding conductor.
Corresponding to each electrode with splicing ear 2 separated partition walls 3 on, be formed with the insulated barriers wall installation portion 4 of convex in the end of partition wall 3.Insulated barriers wall 7 is made of insulation board 6 and the circuit-breaker installation portion 5 that forms concavity, and circuit-breaker installation portion 5 is arranged on the end of insulation board 6.By embedding the insulated barriers wall installation portion 4 of convex from the top with the circuit-breaker installation portion 5 of concavity, chimeric and the card of the insulated barriers wall installation portion 4 of circuit-breaker installation portion 5 and convex of concavity of insulated barriers wall 7 is ended, simultaneously, insulated barriers wall 7 is fixed on the main body 1 of circuit-breaker.
On the partition wall 3 of pedestal 10a, clamping part 8a is set being that partition wall 3 direction of extending is outstanding laterally from pedestal 10a, on the partition wall 3 of lid 10b, from lid 10b be the outstanding clamping part 8b that is provided with of direction that partition wall 3 extends laterally.On the main body 1 of circuit-breaker, by the following side corner sections of the circuit-breaker installation portion 5 of clamping part 8a clamping insulated barriers wall 7, by the last side corner sections of the circuit-breaker installation portion 5 of clamping part 8b clamping insulated barriers wall 7.In addition, clamping part 8c, clamping part 8d are provided with from pedestal 10a, lid 10b are outstanding respectively, under the situation with the main body 1 of a plurality of circuit-breakers and row arrangement, play the effect of the circuit-breaker installation portion 5 of clamping insulated barriers wall 7.Clamping part 8a and clamping part 8c are arranged on the below of splicing ear 2, and clamping part 8b and clamping part 8d are arranged on the top of splicing ear 2.Carry out after with pedestal 10a and lid 10b combination under the situation of installation of splicing ear 2, avoid clamping part 8b and clamping part 8d and splicing ear 2 is installed on the link stroma from oblique upper.
Therefore, because the circuit-breaker installation portion of concavity 5 is chimeric with the insulated barriers wall installation portion 4 that is arranged at the convex on the partition wall 3, and the main body 1 of circuit-breaker constitutes by from the outstanding respectively clamping part 8a of pedestal 10a and lid 10b and the circuit-breaker installation portion 5 of clamping part 8b clamping insulated barriers wall 7, so insulated barriers wall 7 is difficult for coming off from the main bodys 1 of circuit-breaker.Thus, because splicing ear of each electrode 2 and bonding conductor mutually insulated, so can obtain safe circuit-breaker.In addition, if observe main body 1 from the top, then as shown in Figure 3, be arranged on the clamping part 8b of top of splicing ear 2 and the part that clamping part 8d covers splicing ear 2, finger can't insert directly over main body 1, the careless situation that touches the splicing ear 2 of the circuit breaker in the energising particularly can not appear in the therefore fail safe that can improve circuit breaker.
In addition, because insulated barriers wall installation portion 4, clamping part 8a to 8d all have simple structure, and it is uncomplicated, and can be integrally formed when the pedestal 10a of the housing 10 that forms circuit-breaker and lid 10b, therefore can obtain pedestal 10a and lid 10b by qurer, need not through complicated step.
As mentioned above, according to the circuit-breaker in the present embodiment, utilization is arranged on clamping part 8a on the partition wall 3 and 8b clamping and is arranged on circuit-breaker installation portion 5 on the insulated barriers wall 7, thus, even under the situation wall thickness of the splicing ear 2 separated partition walls 3 of circuit-breaker is thin corresponding to each electrode, also with prior art in make partition wall 3 the situation that intensity significantly reduces or insulated barriers wall 7 comes off easily differently, insulated barriers wall 7 can be securely fixed on the main body 1 of circuit-breaker, and can significantly not reduce the intensity of partition wall 3.
In addition, insulated barriers wall installation constitution as circuit-breaker, as shown in Figure 4, can be following structure also: make the insulated barriers wall installation portion 4 of partition wall 3 be concavity, circuit-breaker installation portion 5 has protuberance, with the protuberance of circuit-breaker installation portion 5 with chimeric as the insulated barriers wall installation portion 4 of recess.In this case, because do not have the part of wall thickness attenuation, can improve the intensity of circuit-breaker installation portion 5 at circuit-breaker installation portion 5 places of insulated barriers wall 7.
Even in this case, because the main body of circuit-breaker 1 constitutes by from the outstanding respectively clamping part 8a of pedestal 10a and lid 10b and the circuit-breaker installation portion 5 of clamping part 8b clamping insulated barriers wall 7, so insulated barriers wall 7 is not easy to come off from the main body 1 of circuit-breaker.In addition, under the situation of partition wall 3 attenuation, even the wall thickness attenuation of the insulated barriers wall installation portion 4 of concavity, also can strengthen the insulated barriers wall installation portion 4 of the partition wall 3 of concavity, so the intensity of partition wall 3 is significantly reduced by the clamping part 8a and the clamping part 8b that are arranged on the partition wall 3.Therefore, insulated barriers wall 7 can be securely fixed on the main body 1 of circuit-breaker, and the intensity of partition wall 3 is significantly reduced.
In addition, be illustrated based on pedestal 10a and the outstanding example that clamping part is set of lid 10b from the main body 1 of circuit-breaker, but the some outstanding clamping part that be provided with that also can be from pedestal 10a or lid 10b.In this case, because in the time of in the main body 1 that insulated barriers wall 7 is embedded circuit-breaker, circuit-breaker installation portion 5 only finally carries out gap between the clamping part of clamping by a place, therefore need there be the adjusting between the gap under the situation at two places in the gap between clamping part, the operation that can easily carry out on pedestal 10a, installing lid 10b.In addition, because only there is a place in the gap between clamping part, so can easily insulated barriers wall 7 be installed on the main body 1 of circuit-breaker.
Under the main body 1 and the fixing more weak situation between the insulated barriers wall 7 of circuit-breaker, by increasing the width of clamping part, increase the circuit-breaker installation portion 5 of insulated barriers wall 7 and the contact area between the clamping part, insulated barriers wall 7 can be fixed on the main body 1 of circuit-breaker fully.Perhaps, the fastener that clamping part and circuit-breaker installation portion 5 cards are ended can be set on clamping part also, on circuit-breaker installation portion 5, be provided with engage with this fastener by fastener.So also insulated barriers wall 7 can be fixed on the main body 1 of circuit-breaker fully.By increasing above-mentioned contact area, above-mentioned fastener is set and, insulated barriers wall 7 can be securely fixed on the main body 1 of circuit-breaker more by fastener.
In addition, also can make the outer wide wall thickness of circuit-breaker installation portion 5 identical with partition wall 3.Here, circuit-breaker installation portion 5 outer wide is meant the width with the wall thickness direction equidirectional of insulated barriers wall 7.Thus, will be connected crimp type terminal on the bonding conductor when being connected, and,, can not make to connect operation and become difficulty so can easily connect operation because insulated barriers wall 7 can not interfere with operator's hand or instrument with splicing ear 2.In addition, even under the state that insulated barriers wall 7 is installed, also can with the state that insulated barriers wall 7 is not installed in the same manner, congener crimp type terminal is installed.Also can make the outer wide wall thickness of circuit-breaker installation portion 5 narrow than partition wall 3.Thus, because it is wealthy to broaden near the splicing ear 2 on the main body of circuit-breaker 1, so can more easily carry out above-mentioned connection operation.In addition, because retaining part is above or below the splicing ear 2, so can not hinder above-mentioned connection operation.
In addition, the 2nd insulated barriers wall installation constitution shown in the 1st insulated barriers wall installation constitution shown in Fig. 3 and Fig. 4 suitably can be made up and uses.For example, can make the insulated barriers wall installation constitution of the outer wall section of main body 1 adopt the 1st insulated barriers wall installation constitution, the insulated barriers wall installation constitution of partition wall 3 adopts the 2nd insulated barriers wall installation constitution.
