Abstract

The utility model relates to a combined type surge protector connection structure. The combined type surge protector connection structure comprises one-pole type surge protectors, wherein a surge protection module of each one-pole surge protector is respectively assembled in a base of the one-pole type surge protector, a connection end of one end of each base is embedded with a busbar, a side wall of each busbar is sleeved with an insulation sleeve casing, the other end of the base is respectively arranged with an inward concave long groove, fasteners are mounted between the adjacent inward concave long grooves, a connection portion of each busbar and the surge protection module of each one-pole surge protector is respectively arranged with an inward concave circular groove, a caliber of a notch of the inward concave circular groove is smaller than that of the inward concave circular groove, and each inward concave circular groove is locked and connected with the connection end of one end of each base through a locking piece. According to the combined type surge protector connection structure, the connection portion of an upper end of the busbar and the surge protection module is arranged with the inward concave circular groove, even a locking screw looses, reliable connection of the busbar and the base of each one-pole type surge protector can be guaranteed, so risks of loosening and separation can be effectively avoided, and connection is reliable.

Description

The syndeton of combined electrical surge protector

Technical field

The utility model relates to surge protector, is specifically related to the syndeton of combined electrical surge protector.

Background technology

Combined electrical surge protector of the prior art; to be connected by many identical acyclic type surge protectors to consist of; end at each acyclic type surge protector pedestal relies on bus-bar to connect; the other end at each pedestal relies on metal or nonmetal fastener to connect; connector in this kind structure is away from the termination in the pedestal, thereby can avoid producing between each acyclic type surge protector the hidden danger of interpolar discharge or large voltage breakdown.Yet the bus-bar in the above-mentioned bindiny mechanism and pedestal are fastenedly connected with screw by bus-bar upper end " U " shape groove, and shown in 6 among Fig. 6, wherein 7 for being set in the plastic housing of bus-bar 6 sidewalls.The defective of " U " shape groove is on the above-mentioned bus-bar; in case screw produces loosening; because the A/F of " U " groove is greater than the trip bolt diameter, bus-bar then easily produces slippage with pedestal and separates, and affects reliable shape and fail safe that the combined electrical surge protector uses.

The utility model content

The applicant improves for above-mentioned shortcoming of the prior art; a kind of syndeton of combined electrical surge protector is provided; it has overcome the existing deficiency of " U " shape groove on the bus-bar of the prior art; even trip bolt is loosening; the reliable connection that still can keep bus-bar and each acyclic type surge protector pedestal; effectively avoid the slippage of bus-bar and the risk of separation in the prior art, guaranteed the reliability of syndeton.

The technical solution of the utility model is as follows:

The syndeton of combined electrical surge protector, comprise each acyclic type surge protector, the surge protection module of described each acyclic type surge protector is assemblied in respectively among the pedestal of described each acyclic type surge protector, terminals interlocking at each pedestal one end has bus-bar, and the sidewall sheath of bus-bar has the insulation sheath body; Have the indent elongate slots at each pedestal other end, between adjacent indent elongate slots, fastener is housed; The junction of the surge protection module of bus-bar and each acyclic type surge protector has the indent circular recess; the notch bore of described indent circular recess is less than the bore of indent circular recess, and described each indent circular recess is fastenedly connected by the terminals of securing member and each pedestal one end.

Its further technical scheme is:

Consist of the combined electrical surge protector by three acyclic type surge protectors by described syndeton.

Technique effect of the present utility model:

The utility model is the improvement to combined electrical surge protector syndeton of the prior art; the groove that the junction of the surge protection module of bus-bar upper end and each acyclic type surge protector has is set to the indent circular recess; the notch bore of described indent circular recess is less than the bore of indent circular recess; even trip bolt is loosening; because the notch bore of indent circular recess is less than the diameter of trip bolt; thereby reliable connection that still can keep bus-bar and each acyclic type surge protector pedestal; effectively avoid bus-bar and the slippage of pedestal and the risk of separating in the prior art, guaranteed the reliability of combined electrical surge protector syndeton.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described.

See Fig. 3, the utility model comprises three acyclic type surge protectors, the surge protection module 1 of described each acyclic type surge protector is assemblied in respectively among the pedestal 2 of described each acyclic type surge protector, and be electrically connected with termination in each pedestal 2, the plastic casing at two ends is riveted with plastic rivet respectively in each pedestal 2; Terminals interlocking at each pedestal 2 one end has bus-bar 6, bus-bar 6 upper ends have groove, bus-bar 6 is fastenedly connected by the terminals of described groove and each pedestal 2 one ends, and the sidewall sheath of bus-bar 6 has plastic shell 7, guarantees connection insulation and the safety of each acyclic type surge protector; Protuberance 3 places at each pedestal 2 other end have respectively indent elongate slots 4; between adjacent indent elongate slots 4, fastener 5 is housed; by fastener 5 and bus-bar 6 described three acyclic type surge protectors are connected, become the combined electrical surge protector, as shown in Figure 1 and Figure 2.

Fig. 4 shows the structure of fastener 5, and fastener 5 has certain elasticity, can be by metal or the high plastic production of intensity.

See Fig. 5; the junction of bus-bar 6 upper ends in the utility model and the surge protection module 1 of each acyclic type surge protector has the indent circular recess; bus-bar 6 is fastenedly connected by the terminals of described indent circular recess and each pedestal 2 one ends; the notch bore of described indent circular recess is less than the bore of indent circular recess; even trip bolt is loosening; because the notch bore of indent circular recess is less than the diameter of trip bolt; thereby reliable connection that still can keep bus-bar and each acyclic type surge protector pedestal; effectively avoid the risk of slippage of the prior art and separation, guaranteed the reliability of combined electrical surge protector syndeton.

Above description is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range within protection range of the present utility model, can be done any type of modification referring to claim.
