Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of electrical switches, and in particular to a wiring terminal structure and a contactor. Background Art

[0002] Contactors have been widely used in the field of low-voltage electrical appliances. Contactors are composed of terminal structures, contact systems, arc extinguishing systems, operating mechanisms, housings and other structures; among them, the terminal blocks are used to connect external wires to the contactors.

[0003] Conventional static contacts rely on the interference fit between the convex bump and the housing groove to fix the static contacts. However, during the long-term closing and releasing process of the contactor, the static contacts will be constantly vibrated by the impact force generated by the moving contact. Long-term use will cause wear on the housing groove, causing the static contacts to gradually loosen, thereby causing the electrical performance of the contactor to deteriorate. Utility Model Content

[0004] In view of the above problems, the embodiments of the present application provide a terminal structure and a contactor, which can enhance the fixing effect of the stationary contact and thus improve the electrical performance of the contactor.

[0005] According to one aspect of an embodiment of the present application, a terminal structure is provided, which includes a shell, a side cover, a static contact and an anti-loosening component, the shell is provided with a wiring port connecting the inside and outside of the shell, the side cover is connected to the shell, the static contact is installed between the shell and the side cover, and at least partially extends into the wiring port; the anti-loosening component includes: a side cover baffle, the side cover baffle is connected to the side cover and extends to one side of the static contact, and the side cover baffle abuts against the static contact; a boss, the boss is connected to the extension section of the static contact extending into the inner cavity of the shell, and the boss abuts against the side cover baffle.

[0006] The side shield baffle extends toward one side of the static contact, and the elastic force in the vertical direction generated by its own elastic deformation acts on the static contact, so that the static contact is tightly attached to the shell in the vertical direction, thereby increasing the static friction between the side shield baffle and the static contact and between the shell and the static contact, and can effectively prevent the static contact from loosening; and the boss applies force to one side of the side shield baffle, thereby enhancing the fixing effect of the static contact, thereby improving the electrical performance of the contactor.

[0007] In some embodiments, the boss is away from the stationary contact and faces the side shield baffle, and the boss is inclined toward the side shield baffle.

[0008] The boss is inclined toward the side cover baffle, so that when the side cover is installed into the shell, the side cover baffle first contacts the boss. As the side cover is pressed down continuously, the side cover baffle produces elastic deformation and the deformation gradually increases. The side cover baffle will produce elastic force on the boss, thereby increasing the force on the static contact, which can effectively prevent the static contact from loosening due to the impact of the moving contact.

[0009] In some embodiments, the end surface of the side shield baffle plate close to one end of the static contact is inclined, and the inclined surface of the boss abuts against the inclined surface of the side shield baffle plate.

[0010] By setting the end face of the side cover baffle close to one end of the static contact in an inclined manner, the side cover baffle generates an oblique downward elastic force on the boss during the downward pressing of the side cover. When the bottom of the side cover baffle abuts against the static contact, the bottom of the side cover baffle generates a vertical downward force on the static contact, thereby increasing the static friction between the side cover baffle and the static contact and between the shell and the static contact, effectively preventing the static contact from loosening due to the impact of the moving contact. At the same time, the side cover baffle is tightly fitted with the static contact to prevent dust from entering the inner cavity of the shell from above the static contact.

[0011] In some embodiments, a wiring screw is connected to the side wall of the wiring port, and one end of the wiring screw passes through the static contact and is connected to the shell, and the screw head of the wiring screw and the static contact are used to crimp the wire; the side cover baffle is located on the side of the wiring screw close to the wiring port and close to the shell.

[0012] The wire is crimped through the screw head of the wiring screw and the static contact to achieve the connection between the wire and the static contact, and then the connection between the terminal structure and the wire is achieved. At the same time, by distributing the side shield baffle on the side of the wiring screw close to the wiring port and close to the shell, the wire is completely blocked by the side shield baffle during the crimping process, avoiding the wire being inserted too deep and causing a virtual connection of the wire, and then avoiding the local temperature of the terminal structure being too high and causing damage.

[0013] In some embodiments, a shell baffle is provided on the shell, and the shell baffle is located on a side of the static contact away from the side cover baffle and abuts against the static contact.

[0014] The shell baffle makes it easy to apply force to the side of the static contact away from the side cover baffle, thereby increasing the static friction between the static contact and the shell baffle. At the same time, it blocks dust from entering the inner cavity of the shell from below the static contact, and cooperates with the side cover baffle to form a dustproof structure at the terminal structure position of the contactor, effectively preventing foreign matter from entering the interior of the contactor from the terminal structure.

[0015] In some embodiments, a static contact point is provided at one end of the static contact close to the inner side of the shell, and both ends of the static contact point protrude from the two side surfaces of the static contact. The end of the static contact provided with the static contact point is bent toward the side away from the shell baffle.

[0016] The static contact is used as a fixed electrode to provide a certain degree of constant current or voltage; in addition, the two ends of the static contact protrude from the two side surfaces of the static contact, so that the moving contact can contact the static contact during movement to achieve current transmission or cutting off, and the static contact is provided with a bent setting at one end of the static contact, so that when the static contact is assembled, the static contact position of the static contact avoids the shell baffle to prevent the static contact from interfering with the shell baffle.

[0017] In some embodiments, a convex bump is arranged on the stationary contact, and a groove for engaging the convex bump is arranged on the housing.

[0018] The clamping connection between the static contact and the housing is achieved through the convex bump and the groove, and at the same time, the contact area between the static contact and the housing is increased, thereby increasing the static friction between the static contact and the housing.

[0019] In some embodiments, the side cover is connected to the housing via a snap-fit ​​assembly.

[0020] The buckle assembly facilitates the connection between the side cover and the shell, thereby achieving fixation of the side cover and the shell.

[0021] In some embodiments, the snap assembly includes a protrusion provided on the side cover and a slot provided on the shell, or the snap assembly includes a slot provided on the side cover and a protrusion provided on the shell; the protrusion and the slot are snap-connected.

[0022] The protrusion and the slot are engaged to facilitate positioning of the side cover, thereby achieving engagement between the side cover and the housing.

[0023] According to another aspect of an embodiment of the present application, a contactor is provided, comprising the connection terminal structure of the above embodiment.

[0024] By adopting the above solution, the static friction between the side shield baffle and the static contact and between the shell and the static contact is relatively large, and dust is blocked from entering the inner cavity of the shell from the static contact position, effectively preventing foreign matter from entering the interior of the contactor from the terminal structure, thereby improving the electrical performance of the contactor and extending the service life of the contactor.

[0025] The embodiment of the present application increases the static friction between the side cover baffle and the static contact, as well as between the shell and the static contact, by the abutment between the side cover baffle and the shell baffle and the static contact, which can effectively prevent the static contact from loosening and thereby enhance the fixing effect of the static contact and improve the electrical performance of the contactor; in addition, by means of a boss inclined toward the surface of the side cover baffle, during the process of pressing down the side cover, the side cover baffle generates an oblique downward elastic force on the boss, and when the bottom of the side cover baffle abuts against the static contact, the bottom of the side cover baffle generates a vertical downward force on the static contact, thereby increasing the static friction between the side cover baffle and the static contact, as well as between the shell and the static contact, effectively preventing the static contact from loosening under the impact of the moving contact, and at the same time, making the side cover baffle fit tightly against the static contact to prevent dust from entering the inner cavity of the shell from the static contact position.

[0047] The embodiment of the present application provides a wiring terminal structure, Figure 1 This is a schematic diagram of the overall structure of the terminal block structure provided in the embodiment of the present application. Figure 2 This is an exploded diagram of the terminal block structure. Figure 3 FIG. 4 is a cross-sectional view of the side shield baffle 41 and the housing baffle 43 in abutment with the stationary contact 3, as shown in FIG. Figure 1 , Figure 2 and Figure 3 As shown, the terminal structure includes a shell 1, a side cover 2, a static contact 3 and an anti-loosening component 4. The shell 1 is provided with a wiring port 11 connecting the inside and outside of the shell 1, so that at least part of the static contact 3 can extend into the wiring port 11 and enter the inner cavity of the shell 1; the side cover 2 is connected to the shell 1, and the side cover 2 and the shell 1 are connected by a snap assembly 6, so that the side cover 2 and the shell 1 are fixed; in addition, the side cover 2 is made of a plastic material with good toughness, so that the side cover 2 can be elastically deformed during the installation process; the static contact 3 is installed between the shell 1 and the side cover 2, and the anti-loosening component 4 applies force to the static contact 3, thereby increasing the static friction of the static contact 3 and effectively preventing the static contact 3 from loosening under the impact of the moving contact.

[0048] like Figure 3 and Figure 4As shown, the anti-loosening assembly 4 includes a side cover baffle 41, a shell baffle 43 and a boss 42; the side cover baffle 41 is connected to the side cover 2 and extends to one side of the static contact 3, the side cover baffle 41 abuts against the static contact 3, and the end surface of the side cover baffle 41 close to the static contact 3 is inclined, so that when the side cover baffle 41 abuts against the static contact 3, the component force in the vertical direction generated by the elastic action of the inclined end surface of the side cover baffle 41 close to the static contact 3 acts on the static contact 3; in addition, the corresponding distribution of the side cover baffle 41 and the static contact 3, in this application, the side cover baffle 41 can be four, five, or two, as long as the side cover baffle 41 abuts against the upper surface of the static contact 3, in this embodiment, the side cover baffle 41 is set to four , the four side cover baffles 41 are distributed along the length direction of the side cover 2, and the distance between two adjacent side cover baffles 41 is the same; and, the total length of the side cover baffles 41 is slightly larger than the distance from the side cover 2 to the static contact 3, so that when the side cover 2 and the shell 1 are assembled in place, the bottom of the side cover baffle 41 will abut against the static contact 3, and the bottom of the baffle will also produce elastic deformation, and generate a vertical downward elastic force on the static contact 3, so as to increase the static friction force of the static contact 3; on the other hand, during the crimping process of the wire, the wire will be completely blocked by the side cover baffle 41, so that the wire cannot pass through the side cover baffle 41 from any position, avoiding the wire being inserted too deep to cause the wire to be virtual connected, thereby avoiding the local temperature of the terminal structure being too high and damaged.

[0049] The boss 42 is connected to the extension section of the static contact 3 extending into the inner cavity of the housing 1, and the boss 42 abuts against the side cover baffle 41; and the boss 42 is away from the static contact 3 and faces the side cover baffle 41, and the boss 42 is inclined toward the side cover baffle 41, and the inclined surface of the boss 42 abuts against the inclined end surface of the side cover baffle 41, so that when the side cover baffle 41 abuts against the boss 42, the inclined end surface of the side cover baffle 41 generates an oblique downward elastic force on the boss 42, and the component of the oblique downward elastic force in the horizontal direction acts on the inclined surface of the boss 42, so that the boss 42 and the side cover The baffle 41 is pressed tightly to prevent dust from entering the inner cavity of the shell 1 from above the static contact 3; at the same time, the component of the downward elastic force in the vertical direction acts on the upper surface of the static contact 3, thereby increasing the static friction of the static contact 3; in addition, the bosses 42 in the present application can be two, four, or six, as long as the boss 42 is in contact with the side cover baffle 41. In the present embodiment, two bosses 42 are provided, and the top of the boss 42 is provided with a rounded corner. The two bosses 42 are symmetrically distributed along the central symmetry line of the static contact 3, so that the bosses 42 on the central symmetry line are evenly stressed.

[0050] A shell baffle 43 is provided on the shell 1, and the shell baffle 43 is located on the side of the static contact 3 away from the side cover baffle 41, and abuts against the static contact 3; the shell baffle 43 can be located directly below the side cover baffle 41, so that the shell baffle 43 supports the position where the side cover baffle 41 applies a vertical force to the static contact 3, thereby making the forces applied by the shell baffle 43 and the side cover baffle 41 to the static contact 3 concentrated in the same vertical plane, and the distance between the shell baffle 43 and the side cover baffle 41 is slightly smaller than the thickness of the static contact 3, thereby increasing The shell baffle 43 and the side cover baffle 41 exert an action on the static contact 3, which effectively prevents the static contact 3 from loosening under the impact of the moving contact; the shell baffle 43 can also be staggered with the side cover baffle 41, and a force is applied to the bottom wall of the static contact 3 through the shell baffle 43 to increase the static friction of the static contact 3; in addition, in the present application, the shell baffle 43 can also be set in multiples, and multiple shell baffles 43 can be set in parallel to support the bottom wall of the static contact 3, and at the same time, prevent dust from entering the inner cavity of the shell 1 from below the static contact 3.

In the process of crimping the wire, the wire is extended between the elastic metal gasket 51 and the static contact 3, and the contact area with the wire is increased by the elastic metal gasket 51, so that the wire is crimped between the elastic metal gasket 51 and the static contact 3, thereby ensuring the connection performance of the wire and the static contact 3.

[0052] In addition, in order to facilitate the adjustment of the wiring screw 5, a through hole 21 is opened on the side cover baffle 41. The through hole 21 is distributed corresponding to the wiring screw 5, and the through hole 21 is directly opposite to the wiring screw 5, so that the wiring screw 5 can be adjusted by a screwdriver to achieve the wire crimping between the elastic metal gasket and the static contact 3.

[0054] On the other hand, two rows of anti-slip grooves 33 are provided on the upper surface of the static contact 3, and the two rows of anti-slip grooves 33 are symmetrically distributed about the central symmetry line of the static contact 3, so as to increase the friction between the static contact 3 and the side cover baffle 41, and effectively prevent the static contact 3 from loosening under the impact of the moving contact.

[0055] A convex bump 32 is provided on the stationary contact 3, and a groove 12 for snapping the convex bump 32 is provided on the shell 1. In the present application, the convex bump 32 can be set to two, four, or six, as long as the stationary contact 3 and the shell 1 are snapped together by the convex bump 32 and the groove 12. In the present embodiment, two convex bumps 32 are provided, and the two convex bumps 32 are symmetrically distributed on both sides of the central symmetry line of the stationary contact 3, thereby increasing the contact area between the stationary contact 3 and the shell 1, thereby increasing the static friction between the stationary contact 3 and the shell 1, and at the same time, realizing the snap-fit ​​fixation of the stationary contact 3 and the shell 1.

[0056] On the other hand, two groups of sinking bosses 34 are set on the bottom wall of the static contact 3, and the two groups of sinking bosses 34 are symmetrically distributed on both sides of the central symmetry line of the static contact 3. A sinking groove 13 for clamping the sinking boss 34 is opened on the shell 1, and the sinking boss 34 is set at the end away from the static contact 3 and away from the convex bump 32; during the installation process of the static contact 3 and the shell 1, the local force at the contact position between the static contact 3 and the shell 1 is increased through the sinking boss 34 and the sinking groove 13, and the clamping effect of the static contact 3 and the shell 1 is further enhanced.

[0057] like Figure 5 , Figure 6 and Figure 8As shown, the side cover 2 is snapped together with the shell 1 through a snap assembly 6, which includes a protrusion 62 provided on the side cover 2 and a slot 61 provided on the shell 1, and the protrusion 62 is symmetrically distributed on the opposite sides of the side cover 2, and the protrusion 62 and the slot 61 are snapped together; or, the snap assembly 6 includes a slot 61 provided on the side cover 2 and a protrusion 62 provided on the shell 1, and the slot 61 is symmetrically distributed on the opposite sides of the side cover 2, and the protrusion 62 and the slot 61 are snapped together; so that both sides of the side cover 2 are evenly stressed, and the side cover 2 and the shell 1 are snapped together and fixed.
