Abstract
The utility model discloses a threaded connection structure for a conducting rod and a contactor seat of a vacuum arc extinguish chamber. The threaded connection structure comprises the conducting rod, external threads are arranged at a salient at the lower end of the conducting rod, internal threads are arranged on the contactor seat which is in contact with the salient at the lower end of the conducting rod, and a first circle of welding wire and a second circle of welding wire are arranged on a non-threaded connecting surface where the conducting rod is in contact with the contactor seat in a surrounding manner. According to the threaded connection structure, only the contactor seat part is welded when a component is welded for the vacuum arc extinguish chamber, the connection of the conducting rod and the contactor seat can be welded when being placed in a homogeneous tube of the arc extinguish chamber, the volume of the component in welding is reduced, loading amount of the components in a single furnace can be increased, and the production efficiency is improved; meanwhile, the conducting rod and the contactor seat adopt the welding and the threaded connection, the connection is more reliable, the conducting contact area is increased, and the contact resistance is reduced.
Description
Technical field
The utility model belongs to the vacuum interrupter technical field, relates to a kind of vacuum interrupter conducting rod and contact base screw connection structure.
Background technology
The contact base of vacuum interrupter and the connected mode of conducting rod generally adopt riveted structure at present, or monolithic construction.Yet, the easy sealing-off of riveted structure, bonding strength is low; And the welding of vacuum interrupter must be carried out the welding of parts welding carrying out then homogeneous tube earlier, and riveted joint and these two kinds of structures of integral type are when carrying out the parts welding, and contact base part and conducting rod part must be put into vacuum brazing furnace together and weld.Because the restriction in vacuum brazing furnace space and the limitation in height of conducting rod, stove parts can only be loaded one deck or two-layer in vacuum brazing furnace, the shipped quantity of single stove parts has received great restriction, and production efficiency is low.
Summary of the invention
The purpose of the utility model provides a kind of vacuum interrupter conducting rod and contact base screw connection structure; Contact base part and conducting rod can separate erection welding; Reduce the assembling volume of parts, can increase the assembling quantity of vacuum extinction chamber component list stove, enhance productivity.
The technical scheme that the utility model adopts is; A kind of vacuum interrupter conducting rod and contact base screw connection structure; Comprise conducting rod; Conducting rod lower end projection is provided with external screw thread, is provided with internal thread with the conducting rod lower end contacted contact base of projection, is surrounded with the first lap solder wire and the second circle solder wire on the non-threaded joint face that conducting rod contacts with contact base.
The beneficial effect of the utility model is:
1, the utility model couples together conducting rod and contact base through screw thread; Parts are not welded with conducting rod when welding together; Only carry out the welding of contact base part, sealing-in together when changing to homogeneous tube to the welding of conducting rod has reduced the assembling volume of parts; The assembling quantity of single stove parts is increased greatly, improved production efficiency.
2, the utility model conducting rod and contact base adopt and to be threaded, and make connection more reliable, compare with the riveted type structure that to have increased conductive contact surfaces long-pending, have reduced contact resistance.
3, between conducting rod and contact base, inlay two circle scolders, adopt the mode that is threaded that conducting rod and contact base are coupled together then, improve bonding strength, be difficult for sealing-off.
Description of drawings
Fig. 1 is the utility model vacuum interrupter conducting rod and contact base screw connection structure sketch map.
Fig. 2 is the structure enlarged diagram at A place among Fig. 1.
Among the figure, 1. conducting rod, 2. first lap solder wire, 3. second circle solder wire, the 4. contact base.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
The utility model vacuum interrupter conducting rod and contact base screw connection structure such as Fig. 1, shown in Figure 2; Comprise conducting rod 1; The conducting rod 1 lower end projection contact base 4 that has been threaded is inlaid with the first lap solder wire 2 and the second circle solder wire 3 on conducting rod 1 and non-threaded joint face that contact base 4 contacts.
The use of the utility model vacuum interrupter conducting rod and contact base screw connection structure is; After other parts of contact base 4 elder generations and vacuum interrupter carry out the parts erection welding; Again with the conducting rod 1 that is inlaid with the first lap solder wire 2 and the second circle solder wire 3 through being threaded, assemble up with the vacuum interrupter miscellaneous part then and carry out homogeneous tube and weld.Conducting rod 1 adopts with contact base 4 and is threaded; And the first lap solder wire 2 and the second circle solder wire 3 are through weld conducting rod 1 and contact base 4 after the high temperature melting again; It is more reliable that conducting rod 1 is connected with contact base 4, and it is long-pending to have increased conductive contact surfaces, has reduced contact resistance; Also, conducting rod 1 and contact base 4 be threaded owing to having adopted; Compare with monolithic construction with riveted structure in the past; Conducting rod 1 no longer advances the stove welding with contact base 4 parts together when parts weld; Reduced the volume of parts welding, can increase single stove parts shipped quantity of soldering oven greatly, enhanced productivity.
