Specific structural details about this latch 300 and latch 400 will hereafter be illustrated in detail.

Fig. 3 shows the assembly drawing of the high-voltage plug 200 after having dismantled latch 300 and latch 400. As shown in the figure, the plug body assembly 210 of high-voltage plug 200 is provided with: plug card groove 211, realizes once locking for carrying out card conjunction with the latch button bit 304 on latch 300; Plug chute 212, slides wherein for latch 300; Plug projection 213, carries out coordinating to realize final locking for the CPA projection corresponding to latch 400; Plug slide rail 214, coordinates for the CPA chute corresponding to latch 400 so that latch 400 can slide along it with when being separated in high-tension connector locking; And plug button 215, for pressing the lock release realizing high-tension connector downwards. According to the preferred embodiment of the present invention, the tongue shape thing formed by plug button 215 and plug card groove 211 is unremovably arranged on the plug body assembly 210 of high-voltage plug 200, and typically has elasticity. In addition, limiting section (invisible in figure) it is provided with in the bottom of plug chute 212, move further to socket direction to limit latch 300, and described tongue shape thing recovers elasticity distortion after assembling latch 300, thus plug button 215 can limit assembling after latch 300 leave socket and move further to opposite direction. So, the maximum sliding scale of latch 300 is just defined in certain limit. In addition, when latch 300 slides along plug chute 212, the elasticity of described tongue shape thing also contributes to realizing the once locking of latch 300, about once locking, will hereafter be described by reference to the accompanying drawings in detail.

Fig. 4 shows the CONSTRUCTED SPECIFICATION of the latch 300 that the plug body assembly 210 from high-voltage plug 200 disassembles respectively from front and back. As shown in the figure, latch 300 comprises: latch card groove 301, realizes two locking for carrying out card conjunction with the socket button bit 111 in the jack housing 110 being arranged on high pressure socket 100; Latch block 302, in connector locking operating process with the socket end face 112 of high pressure socket 100 to connecing, latch 300 is moved backward, to realize coordinating of latch button bit 304 and plug card groove 211; Latch slide post 303, for, in junctor separation operation process, sliding after releasing once locking, and stop at the limiting section bottom plug chute 212 in plug chute 212; Latch button bit 304, realizes once locking for carrying out card conjunction with plug card groove 211; And latch button 305, for pressing downwards and make it to carry out pivotable using latch 300 and high pressure socket 100 joint as fulcrum so that latch card groove 301 departs from socket button bit 111 thus realizes two lock releases of high-tension connector. It needs to be noted, according to being arranged at the described ad hoc structure of this latch 300 of high-voltage plug 200 side and corresponding mode of operation thereof, not only make the locking process of the high-tension connector of the present invention can complete by simple operation is disposable, thus avoid lock or leakage lock by mistake, and twice latch-release can be realized in high-voltage plug side with compact structure. In addition, owing to latch 300 constructs on the whole in the form of sheets, so it can not have influence on the physical dimension of high-voltage plug 200 significantly, in other words, according to the high-tension connector of the preferred embodiment of the present invention in physical dimension with adopt single card button/engagement part low voltage connector roughly the same.

Fig. 5 demonstrate the high-voltage plug 200 assembling latch 300 and latch 400 lock with corresponding high pressure socket 100 before state. As shown in the figure, latch 300 and latch 400 are assembled on the plug body assembly 210 of high-voltage plug 200. In Figure 5, socket button bit 111 is roughly the same with the single engagement part adopted on traditional junctor, the guide rail being arranged at socket button bit 111 both sides slides the respective slide slots (in figure invisible) of high-voltage plug 200 1 side is inner, when socket end face 112 at high pressure socket 100 is finally connected to limiting section (invisible in figure) of high-voltage plug 200 inside, between high pressure socket and high-voltage plug, just stop relatively sliding. As can be seen from Figure 5, owing to the improvements major embodiment of the present invention is in high-voltage plug one side, the structure of high pressure socket one side is substantially substantially without the need to variation, and this changes in saving also has advantage in upgrade cost. Forming with it comparison, the open CN104348024A of the Chinese patent mentioned in background technology, then must all carry out structural change to high-voltage plug and high pressure socket both sides, just can realize two lockings and twice lock release.

Fig. 6 shows the CONSTRUCTED SPECIFICATION of the latch 400 as CPA (connectorpositionassurance) respectively from front and back. Described latch 400 is mainly used in locking further after high-voltage plug 200 and high pressure socket 100 are locked each other completely, to prevent the pine that meets accident because of plug button and latch button down activity is de-. As shown in the figure, latch 400 has the CPA chute 401 matched with plug slide rail 214; And the CPA projection 402 corresponding with plug projection 213. Described two groups of projections send the sound in the process of staggered cooperation because of shock, such that it is able to clearly alert completes locking. Incidentally, owing to the one end being close at plug bonnet 270 and latch 400 has recess, its width is less times greater than the width of latch 400, so latch 400 can not come off because of firmly excessive when releasing locking. Compared with the locking sliding block that CN104348024A open with prior art Chinese patent records, because without the need to ejection two card buckle portions in plug orientation, and be only to be perpendicular on the direction of plug orientation to prevent plug button 215 movable downwards, so latch 400 structure is simple and be easy to manufacture significantly.

According to above-mentioned description taken in conjunction with the accompanying drawings, the construction package realizing the disposable locking of high-tension connector and twice lock release can be found out, in flat configuration in monnolithic case size, and release, by sheet latch, twice lock release that locking realizes high-tension connector respectively two positions. According to the preferred embodiment of the present invention, described construction package and the corresponding construction assembly of latch 300 and latch 400 by arranging on plug body assembly 210 carry out co-ordinate motion, so that it may with simple to operate and compact construction realize the present invention high-tension connector plug and socket between locking be separated.

Below, composition graphs 7A-D and Fig. 8 A-D explains the high-voltage plug of the present invention and the concrete steps of the enforcement locking of high pressure socket and lock out operation.

First, the locking operation step of the high-tension connector of the present invention is described with reference to Fig. 7 A-D. As shown in Figure 7 A, the high-voltage plug 200 being assembled with latch 300 and latch 400 is directed at the socket key mapping of high pressure socket 100, along the direction driven forward shown in arrow. At this moment, latch 400 is in the de-state of pine, thus plug button 215 and latch button 305 are also just in and movable pine can take off state downwards. Then, as shown in Figure 7 B, when the latch block 302 of the socket end face 112 with latch 300 that are pushed into high pressure socket 100 contacts, under the effect of thrust, force the latch slide post 303 of latch 300 to slide in plug chute 212, and leave the limiting section bottom plug chute 212 and retreat. Then, as seen in figure 7 c, after being pushed into a segment distance, the latch button bit 304 at latch 300 back side falls in plug card groove 211, during this slip both along the upper and lower being perpendicular to slip direction to occurring corresponding elasticity be out of shape. Now, latch 300, again under the stop of plug button 215, makes latch card groove 301 buckle socket button bit 111 completely. In other words, the card of latch button bit 304 and plug card groove 211 is buckled and the card of latch card groove 301 and socket button bit 111 is buckled, it is the relatively sliding between general high-voltage plug 200 and high pressure socket 100 and completes once, thus not only simple to operate but also can avoid as prior art, there is locking by mistake or the situation of leakage locking. Conveniently, in this case, the signal pin of high-voltage plug and high pressure socket and power pin are all in connection state, about electric connection mode and the physical structure of signal pin and power pin, emphasis place that is completely identical with prior art and also non-invention, therefore be omitted at this. Finally, as illustrated in fig. 7d, along direction of arrow driven forward latch 400, plug button 215 is stoped also and then to stop latch button to move for 305 times, and under the acting in conjunction of CPA projection and plug projection, latch 400 is made to move to fully locked position, to prevent latch 400 retreats and the pine that meets accident is de-. The sound sent because misplacing collision each other by the plug projection of the CPA projection of latch 400 and plug body assembly 210, so operator can easily confirm to lock completely. In this case, high-voltage plug 200 and high pressure socket 100 realize locking completely and reliably lock.

Next, the lock out operation step of the high-tension connector of the present invention is described with reference to Fig. 8 A-D. As shown in Figure 8 A, the high-voltage plug 200 of high-tension connector and high pressure socket 100 are in complete locking state. Now, latch card groove 301 buckles socket button bit 111 completely, and latch button bit 304 falls in plug card groove 211 and latch 400 is in fully locked position, and latch 400 is in locking position. As shown in Figure 8 B, then, latch 400 i.e. CPA mechanism is retreated, so that plug button 215 becomes the state that can press downwards along the direction of arrow. Then, as shown in Figure 8 C, press down plug button 215, until making the latch button bit 304 of latch 300 depart from plug card groove 211 because of elasticity distortion, high-voltage plug 200 is pulled backward along the direction of arrow simultaneously, until latch slide post 303 is resisted against the limiting section of the bottom of plug chute 212 and cannot move, thus achieve a lock release. Now, signal pin disconnects, and power pin still contacts and realizes high-voltage interlocking function. Now, systems axiol-ogy is electrically connected to high-voltage plug 200 and high pressure socket 100 for disconnecting, and just automatically stops being powered by two cables, thus ensures the security that high-tension connector operates, prevents security incident. Finally, as in fig. 8d, press down latch button 305 further, until making latch card groove 301 and socket button bit 111 depart from because of elasticity distortion, draw after high-voltage plug 200 along the direction of arrow simultaneously, so that high-voltage plug 200 is separated completely with high pressure socket 100, thus achieve two lock releases.

Above preferred embodiment according to the present invention, special sheet latch it is provided with in high-voltage plug side, described inserted pin special has the latch card groove carrying out card with the socket button bit being arranged at high pressure socket side and closing, described inserted pin special can slide certain distance scope in the plug chute of high-voltage plug, and can be positioned the specific position of high-voltage plug by latch button bit. Thus, the high-tension connector of the present invention not only compact construction, and achieve high-voltage plug and can must be separated completely by twice lock release in the process being separated with high pressure socket, thus improve safety performance. Simultaneously, in the locking process of high-voltage plug and high pressure socket, the card of latch button bit and plug card groove is buckled and the card of latch card groove and socket button bit is buckled, relatively sliding between general high-voltage plug and high pressure socket completes once, compared with prior art, not only significantly simplify locking operation, and can avoid in locking process, lock or leakage lock by mistake. In addition, the high-tension connector of the present invention, by means of latch ad hoc structure and with high-voltage plug coordinate mode, avoid and frequently operate engagement part in locking process, such that it is able to improve engagement part work-ing life.

In addition, although in above-mentioned the preferred embodiments of the present invention, arranging latch in high-voltage plug side, adopting traditional single buckle structure in high pressure socket side, thus in the sepn process of high-voltage plug and high pressure socket, realizing twice lock release. But, those skilled in the art can also easily associate, and adopts and arranges similar latch structure in high pressure socket side, and adopt traditional single buckle structure in high-voltage plug side, to realize described twice lock release equally. Equally, structure is connected about contact pin and jack and other pairings, it is also possible to be arranged at high-voltage plug side or high pressure socket side as required flexibly, and be not limited to the situation of the preferred embodiment of the present invention.

In addition, although in above-mentioned the preferred embodiments of the present invention, it is illustrated for high-tension connector, but the structure of the present invention can also be applied to other junctors such as low voltage connector as required, as long as need the situation realizing twice lock release in two positions, place respectively in the sepn process of junctor, so that it may to utilize the connection structure of the present invention. Such as, may damage when relevant electric installation normal operation such as loses significant data in the direct power-off of junctor, adopt the structure of the present invention that such problem just can be avoided to occur.

In addition, in above-mentioned the preferred embodiments of the present invention, latch and plug body assembly adopt the mode of CPA projection and plug projection to carry out shrink-fit to realize final locking respectively, but its side or two sides can also suitably be changed to as required convex bar realize locking.
