Abstract
The utility model discloses an improved conformation of a quincunx contact, which comprises movable contact pieces, blade springs and an annular contact piece stand, wherein the movable contact pieces and the blade springs have a plurality of pairs and respectively penetrate into positioning holes on the annular contact piece stand along circumferential direction, two ends of each blade spring are connected at two ends of the corresponding movable contact piece, and the middle portions of the blade springs are propped on the side walls of the positioning holes of the annular contact piece stand. When the improved conformation of the quincunx contact is inserted in a static contact, the quincunx contact can lead the contact piece and the static contact to be reliably connected through the action of the pressure on both ends of the blade springs and the support of the annular contact piece stand, the entire manufacturing technology is simple, and the pressure of the contact is large. Each contact piece is also provided with an R angle wiring groove, thus the heat dissipation property of the entire contact is enhanced, and the insulating property and exquisite appearance of a circuit breaker are guaranteed.
Description
Technical field
The utility model discloses a kind of improvement structure of Mume flower contact, belongs to killer switch manufacturing technology field.
Background technology
A kind of Mume flower contact is arranged on the market, be to be combined into one by moving contact contact, ring spring and contact frame, fixed contact inserts during use, the moving contact contact of Mume flower contact is connected with the dynamic/static contact contact under the effect of ring spring and contact frame, the effect of ring spring is to guarantee contact pressure, but owing to the restriction of its structure causes the part contact not reach the situation generation of position.Simultaneously, Mume flower contact is easy to generate heat in galvanization, and the material of ring spring is easily loosening in the back that is heated, and causes whole contact loose contact, thereby has influenced the normal use of circuit breaker.
The inventor is engaged in the circuit breaker research and development for many years, creates a novel Mume flower contact, so proposition of the present utility model is just arranged.
Summary of the invention
At the deficiency of existing Mume flower contact contact technique, the utility model provides a kind of improvement structure of rational in infrastructure, Mume flower contact that contact pressure is big.
For achieving the above object, the utility model is achieved through the following technical solutions:
The utility model is to be combined by moving contact contact, sheet spring and annular contact frame, how right moving contact contact and sheet spring are, along the location hole that circumferentially is arranged in respectively on the annular contact frame, and each sheet spring two ends is connected in the two ends of corresponding moving contact contact, and the middle part of sheet spring is supported on the sidewall of location hole of annular contact frame.
Further, there is through hole at described annular contact frame center, and each location hole is along the central through hole circumferential distribution of contact frame.
Further, described moving contact contact and sheet spring are six pairs, each moving contact contact and the shape setting ringwise of sheet spring, and each moving contact contact is provided with R linea angulata groove.
The utility model Mume flower contact is combined by moving contact contact, sheet spring and annular contact frame, when when fixed contact inserts, Mume flower contact is by the effect of sheet spring pressure at two ends and the support of annular contact frame, contact reliably is connected with fixed contact, adopt ring spring to guarantee contact pressure before having avoided, and the situation that causes the part contact not reach the position takes place, also avoided simultaneously spring loosening in the back that is heated, causing whole contact loose contact, is the loosening of single spring and adopt the contact of sheet spring formula.And whole manufacturing process is simple, and contact pressure is big.Each contact has also designed R linea angulata groove, improves the heat dispersion of whole contact, has guaranteed the insulation property and the exquisite outward appearance of circuit breaker.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is a vertical view of the present utility model;
Fig. 3 is that Fig. 2 is the A-A cutaway view.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Embodiment: structure such as Fig. 1, Fig. 2 and shown in Figure 3, the utility model is combined by moving contact contact 1, sheet spring 2 and annular contact frame 3, how right moving contact contact 1 be with sheet spring 2, along the location hole 30 that circumferentially is arranged in respectively on the annular contact frame 3, and each sheet spring 2 two ends is connected in the two ends of corresponding moving contact contact 1, and the middle part of sheet spring 2 is supported on the sidewall of location hole of annular contact frame 3.There is through hole 31 at annular contact frame 3 centers, and each location hole 30 is along central through hole 31 circumferential distribution of contact frame.
Moving contact contact 1 is six pairs with sheet spring 2, each moving contact contact and the shape setting ringwise of sheet spring, and each moving contact contact is provided with R linea angulata groove 10.
The utility model is when when fixed contact 4 inserts, Mume flower contact reliably is connected contact with fixed contact by the effect of sheet spring pressure at two ends and the support of annular contact frame, is the loosening of single spring and adopt the contact of sheet spring formula, and whole manufacturing process is simple, and contact pressure is big.Each contact has also designed R linea angulata groove, improves the heat dispersion of whole contact, has guaranteed the insulation property and the exquisite outward appearance of circuit breaker.
The above record only for utilizing the embodiment of this origination techniques content, anyly is familiar with modification, the variation that this skill person uses this creation to do to do, and all belongs to the claim of this creation opinion, and is not limited to those disclosed embodiments.
