It is not intended to limit the scope of the invention. It is pointed out that in the following detailed description and in the appended claims, for convenience, the end of the male contact to be combined with the female contact is referred to as the front end or the joint end, and the transposition with the isolating switch One end to which the mechanism is connected is referred to as a rear end or a connection end; and therefore, in the male contact, one end of the joint end of each member closest to the female contact is also referred to as a front end, and the opposite end is referred to as a rear end. The direction toward the joint end in the male contact is referred to as the forward direction, and vice versa.

1 is a view showing a male contact 100 according to a preferred embodiment of the present invention, and FIG. 2 is a view of FIG. A side view of the structure of the male contact shown. The male contact 100 includes a conductive arm 101 connected to the transposition mechanism of the isolating switch, a connecting block 102 disposed at the front end of the conductive arm, and a front end disposed at the front end of the male contact 100 in a direction from the rear end to the front end. A plurality of contact flaps 103, an access cap 104 disposed at a front portion of the contact flap 103, and a push rod 105 slidably passing through a through hole (not shown in FIG. 2) provided in the connection block 102 and pushing the contact flap 103 And four shields 107 disposed on the outside of the male contacts.

Referring to Figures 1, 2 and 4, the cap 104 is disposed at the front end of the male contact 100, and the cap 104 is coupled to the connecting block 102 by a plurality of bolts 1041 (four in this embodiment). The bolts 1041 sequentially pass through the four holes 1042 of the contact cap 104, a corresponding number of oblique holes 1031 provided in the contact flaps 103 (see FIGS. 5A and 5B), and the putter heads 1052 disposed at the front end of the push rods 105. The thread is connected to a threaded hole (not shown) of the connecting block 102.

As shown in FIG. 4, the push rod 105 includes a shaft 1051 and the above-described push rod head 1052. The shaft 1051 slidably passes through a through hole provided in the connecting block 102 and the transmission arm 101 and the transposition mechanism of the isolating switch. The pieces are connected, thereby being pushed or pulled by the transmission member during the closing and opening, so that the push rod 105 can slide in the axial direction of the male contact 100. The pusher head 1052 is generally square in shape, and the four bolts 1041 that connect the contact caps 104 are slidably passed through the four semicircular grooves 10521 without interfering with the movement of the pusher. In addition, arcuate recesses 1053 are provided on the four sides of the front end of the pusher head 1051, and the arcuate recesses 1053 extend along four sides to accommodate the bottom 1032 of the contact flap 103 (see Figs. 5A and 5B). .

Referring to Figures 2, 4 and 5A, 5B, as shown in Figure 5A, the contact flap 103 has a generally trapezoidal shape in a front view, the width of the bottom portion 1032 is smaller than the width of the top portion, and a skew hole 1031 is formed in the bottom portion 1032 so that A bolt 1041 connecting the cap 104 passes therethrough. The oblique hole 1031 is a non-cylindrical hole, and the front and rear ends of the hole are widened, and the center is a circular hole so as not to be interfered by the bolt 1041 during the movement of the contact flap. For example, the angled aperture 1031 can be achieved by drilling a hole in the contact flap 103 at two intersecting angles.

At a substantially intermediate position behind the contact flap, for example, by soldering a soft connection 106, the rear end of the soft joint 106 is fixed to the conductive arm 101 by, for example, a bolt or the like to connect the contact flap 103 with the conductive arm 101.

On the outer side of the male contact 100, a shield 107 is provided. In the present embodiment, the shield 107 is made of a metal plate and has a plate shape with a wave shape in the middle, and is axially symmetrically fixed on the four sides of the outer side of the conductive arm, and the contact flap is disposed between the contact cap and the push rod. 103, the bottom 1032 is snail passing through the hole 1031 The peg 1041 is confined within the arcuate recess 1053, and the contact flap is only rotatable about the arcuate recess 1053. As the pusher slides forward, the contact flap 103 slides against the contact cap 104 to an upright position. On the other hand, when the push rod slides rearward, the contact flap 103 is gradually tilted from the upright position by the interference of the front end of the guard 107, thereby forming a reliable position corresponding action.

In addition, the shield 107 encloses the soft connection 106 and other parts on the inside to provide protection against dust, rain and the like.

A pressure plate 1048 is provided at the front end of the cap to fix the bolt and the contact cap after the male contact is installed and installed to prevent the contact from damaging the contact.

The assembled male contact 100 will now be described with reference to Figures 2 and 3. 2 shows the male contact 100 in the state in which the flap is tilted, and FIG. 3 shows the male contact 100 in the upright state of the contact flap.

As shown in FIG. 2, after the male contact 100 is mounted to the indexing mechanism of the isolating switch, the lower end of the contact flap 103 fits within the arcuate recess of the putter head 1052, and the cap 104 utilizes four bolts 1041. It is fixed to the connecting block 102, and the front end of the contact flap 103 abuts on the contact cap 104. The shield is screwed to the conductive arm 101 while the soft connection 106 is connected to the conductive arm. The push rod 105 is coupled to the transmission member of the shifting mechanism of the isolation switch.

Next, the operation of the male contact and the fracture assembly according to the present invention will be described with reference to Figs. 2 and 3.

When the male contact 100 is engaged with the corresponding female contact, as shown in FIG. 2, the contact flap 103 of the male contact 100 is inserted in a tilted state (for the double-column split-type disconnector to be screwed in) to When the contact of the female contact is surrounded by the contact of the female contact, the active side of the isolating switch continues to rotate, and the transmission member of the transposition mechanism of the isolating switch moves forward, thereby being touched by the putter head 1051 The bottom of the flap 103 is pushed forward, since the front side of the flap 103 rests on the contact cap 104 and the cap 104 is fixed relative to the connecting block 102 by means of the bolt 1041, so that the contact flap 103 is in contact with While the rear surface of the cap slides, it swings from the inclined state as shown in FIG. 2 to the upright state shown in FIG. 3, that is, the outwardly expanding of the contact flap 103 gradually pushes away the finger, so that the contact flap 103 and the female contact are The fingers are in close contact. The final female and male contacts 100 are joined together. And during the bonding process, it can be seen that there is slight friction between the contact 103 of the male contact 100 and the front end of the contact of the female contact, thereby removing the oxide film, and the isolation switch can be operated in a long-term outdoor operation. The front and rear contacts of the fracture assembly are in good electrical contact.

During the opening process, the push rod 105 of the male contact 100 is pulled backward by the transmission member of the transposition mechanism of the isolating switch, so that the contact flap 103 loses support and is tilted forward under the constraint of the guard plate, thereby, the male touch head The contact flap 103 of 100 is contracted and is unobstructed from the female contact 200 after being sufficiently contracted, and the contracted state of the contact 103 of the male contact 100 (dumped state) is as shown in FIG.

In addition, in contrast to the fracture assembly of the prior art, as in the fracture assembly described in the applicant's prior Chinese Patent Application No. 200910211917.2, in the present invention, the female contact is mounted on the opposite side of the isolating switch The function of the male contact depends on the movement of the push rod passing through the conductive arm. In the splitting action, the exposed conductive arm does not move relative to the transposition mechanism, so that the reliability of the mechanism is improved.

Although the preferred embodiments of the present invention have been described in detail with reference to the drawings, the present invention is not limited to the described embodiments. For example, the screws 1041 that fix the cap 104 are not limited to four, but may be three or more than four. The cap 104 is not limited to the form described above. For example, as shown in FIGS. 6A and 6B, the front end of the cap 104 is convex, and a card groove for accommodating the collar is provided around the protrusion, and a recess is provided at the front. a pit 1043 to trap the bolt head of the bolt 1041 into the recess 1043, the open annular collar 1044 can be snapped into the slot to hold the bolt head in place and elastically center the bolt Tightening, thereby making the movement of the flap more accurate.

Next, a male contact according to a second embodiment of the present invention will be described with reference to Figs. 7-10. The same components are given the same reference numerals.

As shown in FIG. 7, FIG. 8A, FIG. 8B and FIG. 9, the male contact 100 according to the second embodiment of the present invention also includes the contact flap 103 and the contact cap 104. Unlike the first embodiment, the contact flap 103 is further disposed. There is a curved guide rail 1032. Cooperating with the curved guide rail 1032, a slot-shaped slide 1045 is provided in a plate-like base body of the contact cap 104 so as to radiate centrally, and in the slide 1045, a guide is also disposed transversely. A rod 1047 is inserted into the slide 1045. And the guide rod 1047 passes through the slot in the middle of the curved guide rail 1032 of the contact flap 103. Thus, during the swinging of the contact flap 103 between the tilted position and the upright position, the curved guide rail 1032 of the contact flap 103 will cooperate with the passage formed by the slide 1045 and the guide rod 1047 in the contact cap 104 to thereby touch The movement of the flap 103 is guided such that the contact flap 103 is reliably in an upright position as the pusher 105 is pushed forward, and the flap 103 can be reliably poured when the pusher pulls back on the contact flap 103.

As shown in FIG. 10A and FIG. 10B, in order to prevent the contact flap 103 from jumping or disengaging from the groove 1053 in the curved groove 1053 of the pusher head during the movement, the contact flap 103 is symmetrically opened near the bottom. There are two oblique holes 1031, and correspondingly, a U-shaped hoop spring 1054 made of a round wire is provided around the putter head. Referring to FIG. 10, the hoop spring is further provided with a 90-degree vertical bend near the U-bend to avoid the push rod shaft, and the hoop spring 1054 is axially caught in the groove on the side of the pusher head from the periphery, and The piercing hole 1031 is inserted into the oblique hole 1031 of the contact flap 103, for example, by drilling the contact flap 103 in two angled directions, whereby the coil spring 1054 can prevent the contact flap 103 The jumper spring 1054 does not interfere with the swinging motion of the contact flap 103. The loop spring structure described in this embodiment is only an implementation manner, and is not limited to this structure, but penetrates The way can also be from front to back.

As shown in FIG. 7 and FIG. 9, in the second embodiment according to the present invention, the replacement cap 104 is fixed to the conductive arm 101 by four bolts 1041, and the cap link 1046 is used, and the cap link 1046 is used. The center position of the rear side of the contact cap 104 may be integral with the contact cap 104, or may be separately manufactured and joined together by welding or the like. The cap link 1046 extends from the contact cap 104 to the conductive arm 101. In this case, the push rod 105 is hollow and slidably fitted over the outside of the contact cap 1046. It should be noted that the connection manner of the contact cap and the connecting rod can completely adopt other connecting manners, for example, a threaded connection can be adopted.

As shown in the right part of Fig. 7 (i.e., near the side of the conductive arm), in order to fix the contact rod link 1046 to the conductive arm 101, the outer circumference of the hollow push rod 105 is symmetric on both sides, axially spaced apart by a certain distance. Four long slots 1055 are formed, and four connecting pins 1011 disposed at corresponding positions on the conductive arm 101 are respectively connected to the contact cap connecting rod 1046 through the four long slots, only one corresponding position is shown in the figure. The connecting nail 1011 and the long groove, the connecting nail is connected with the contact cap connecting rod 1046, and the other end of the connecting nail is fixed in a hole formed at the side of the connecting block 102 at the front end of the conductive arm, thereby fixing the contact cap connecting rod 1046. Connected to the conductive arm 101. At the same time, since the four connecting nails respectively pass through the long grooves on the outer circumference of the push rod, the push rod 105 is guided during the axial movement of the push rod, and it is undoubted that according to the different needs of the assembly size, The connection of the connecting rod and the connecting block can be completely connected by a pin.

In the second embodiment, the contact flap 103 and the curved guide rail 1032 can be joined together, for example, by a welding method. In this embodiment, due to the presence of the curved guide rails 1032, the shields mounted on the four sides of the contacts may serve only as a shield and do not participate in the action of the contact members.

Other structures of the second embodiment are the same as those of the first embodiment, and are not described herein again. Compared with the first embodiment, the structure of the second embodiment is mainly to make adjustment easier.

However, since the curved guide rail is arranged on the contact flap, and the guide groove needs to be processed in the contact cap, the processing of the arc guide rail selection and welding and the contact cap slide is difficult. In order to overcome this problem, as shown in Figs. 11 and 12, a third embodiment is provided.

As shown in Fig. 11, in the third embodiment according to the present invention, the guide rails of the slide cap, the guide bar 1047 and the contact flap 103 of the cap 104 are removed. Thus, as shown in FIG. 12, the front side of the cap 104 is based. The upper surface is provided with an eye contact link 1046 at a position substantially at the center of the rear side of the contact cap. The cap link 1046 is attached to the conductive arm 101 in the same manner as in the second embodiment.

In the front portion of the push rod 105, similar to the second embodiment, a pusher head is provided, and a hoop spring 1054 is provided around the pusher head. Similarly, a skew hole 1031 is provided in the contact flap 103, into which the hoop spring 1054 is inserted to prevent detachment from the recess 1053 during movement of the contact flap 103.

As shown in Fig. 11, in the third embodiment, when the push rod 105 is pushed forward, the tip end of the contact flap 103 slides on the rear side of the contact cap 104 while swinging from the inclined position to the upright position. When the push rod 105 moves in the opposite direction, the bottom end of the contact flap 103 located in the recess 1053 is pulled backward by the push rod 105, and at the same time, the rear side of the contact flap 103 interferes with the front end of the shield 107, so that the contact flap 103 completes the dumping action, which also enables the contact flap to act on a predetermined trajectory.

It can be seen that the male contact according to the third embodiment of the present invention removes the guide rails in the curved guide rail and the contact cap in the second embodiment, thereby making the structure of the male contact simple and easy to process. Meanwhile, the male contact of the third embodiment also has the effect of easy adjustment in the second embodiment.

Further, in the above embodiment, during the closing process, the contact flap 103 of the male contact 100 is pushed by the push rod 105, thereby swinging from the tilted state to the upright state. However, the present invention can also be implemented as follows: As shown in FIG. 13, the contact cap 104 is coupled to the transmission member of the transposition mechanism via a link 1046, and the push rod is fixed to the conductive arm 101 through the connection block and relative to the conductive arm 101. fixed. Thus, during the closing process, the cap 104 is moved toward the rear end under the pulling of the transmission member of the indexing mechanism, thereby swinging the tab 103 from the tilted state to the upright state.

Alternatively, the soft joint 106 can be soldered directly to the conductive arm instead of being clamped to the conductive arm by bolts as described above.

Although the present invention has been described by taking a male contact having a four-sided structure as an example in the above description, the present invention is not limited thereto, and a male contact having a hexagonal structure or even an octagonal structure may be used. These variations are intended to be covered by the scope of the invention. Therefore, various modifications and alterations may be made by those skilled in the art without departing from the scope of the invention.
