Description

Technical Field

[0001] The utility model specifically relates to a wiring structure and an auxiliary contact. Background Art

[0002] With the cost control, for existing accessories such as auxiliary contacts, the connection between plastic parts has changed from traditional screw and rivet connections to more applications of snap, ultrasonic, hot riveting / rotary riveting and other processes, especially in accessory products.

[0003] Secondly, due to the development trend of product miniaturization, customers have higher and higher requirements for product volume / width, further compressing the wall thickness of plastic parts.

[0004] There are several wiring structures in various accessories. The wiring structure includes a groove opened near the short side wall of the base, a screw washer arranged in the groove, a wiring board arranged below the screw washer, and a screw passing through the screw washer and connecting to the wiring board. Since the washer is square and fits the shape of the groove, when screwing the screw during wiring, the washer will also bear corresponding torque. At this time, the corner adjacent to and rotating towards the short side wall of the base will transmit the torque to the short side wall of the base, resulting in damage and white edges on the short side wall of the base. And due to the rotation of the washer used, obvious imprints are pushed out on the side wall or the side wall bulges outwards, reducing the insulation strength, resulting in poor customer experience and even complaints. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a wiring structure and an auxiliary contact.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A wiring structure, which includes a housing formed by the cooperation of a first housing and a second housing. At least two pole cavities are arranged in the housing, a loop conductive part is arranged in the pole cavity, and an installation groove for placing a screw and a washer is arranged on the upper side of the loop conductive part. The washer is rectangular. At least two avoidance grooves are symmetrically arranged on the groove wall of the installation groove. The avoidance grooves are integrally formed on the first housing and the second housing, and there is a gap between the groove wall of the installation groove and the washer. The avoidance grooves are located at two corner parts on the same side of the washer, and at least one of each corner part of the washer is a first corner part. The first corner part is located near the first housing or the second housing, and rotates towards the direction where the first housing or the second housing is located when the washer deflects slightly clockwise or counterclockwise. When the washer deflects counterclockwise, its first corner part is always in the avoidance groove and there is always a gap between the first corner part and the groove wall of the avoidance groove.

[0008] The inner wall of the avoidance groove is a plane or a curved surface.

[0009] There are two corners of the tile gasket close to the first housing or the second housing, one of which is the first corner and the other is the second corner, and the second corner rotates in a direction away from the first housing or the second housing when the tile gasket deflects slightly clockwise or counterclockwise.

[0010] The groove wall of the installation groove located at the rear end of the loop conductive part is formed by the inner wall perpendicular to the first housing or the second housing.

[0011] There are two corners at the rear end of the tile gasket, and the corner close to the first housing is the first corner, then the corner close to the second housing is the third corner, and the third corner or the first corner contacts the inner wall when the tile gasket deflects slightly clockwise or counterclockwise.

[0012] An auxiliary contact includes a housing formed by the cooperation of a first housing and a second housing. At least two pole cavities are provided in the housing. A loop conductive part is provided in the pole cavity, and an installation groove for placing a screw and a tile gasket is provided on the upper side of the loop conductive part. A static contact is provided on the loop conductive part. A movable contact assembly that can move axially is provided in the housing, and the movable contact assembly can form a make-and-break cooperation with the static contact. The tile gasket is rectangular. At least two avoidance grooves are symmetrically provided on the groove wall of the installation groove. The avoidance grooves are integrally formed on the first housing and the second housing, and there is a gap between the groove wall of the installation groove and the tile gasket. The avoidance grooves are located at two corners on the same side of the tile gasket, and at least one of each corner of the tile gasket is the first corner, and the first corner is located near the first housing or the second housing, and rotates in the direction of the first housing or the second housing when the tile gasket deflects slightly clockwise or counterclockwise. When the tile gasket deflects counterclockwise, its first corner is always in the avoidance groove and there is always a gap between it and the groove wall of the avoidance groove.

[0013] There are four pole cavities, which are respectively located on both sides of the movable contact assembly.

[0014] There are two groups of the loop conductive parts, two in each group, and they are arranged in layers on both sides of the movable contact assembly.

[0015] The beneficial effects of the present utility model: By providing avoidance grooves on the first housing and the second housing, when the screw is twisted, the corners of the tile gasket can always be placed in the avoidance grooves when the tile gasket deflects passively, and will not directly contact the outer wall of the housing, avoiding or reducing the torque transmitted to the sharp corners of the tile gasket, and preventing obvious imprints from being pushed out on the outer wall or the outer wall protruding outward due to the rotation of the tile gasket.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back,...) are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0021] Since two sets of loop electrodes are symmetrically arranged in this application, the front end in this application refers to the side of the loop electrode close to the moving contact assembly, and the rear end refers to the side of the wiring. Since the two loop electrodes are symmetrically structured left and right, there will be two front ends of the loop electrodes in Figure 1 both referring to the side close to the moving contact assembly 700.

[0022] Such as Figure 1 and Figure 2As shown in the figure, the utility model discloses a wiring structure, which comprises a housing 100 formed by the cooperation of a first housing and a second housing. At least two pole cavities 200 are arranged in the housing 100. A loop conductive member 400 is arranged in the pole cavity 200. An installation groove 300 for placing a screw 600 and a washer 500 is arranged on the upper side of the loop conductive member 400. The washer 500 is rectangular. At least two avoidance grooves 310 are symmetrically arranged on the groove wall of the installation groove 300. The avoidance grooves 310 are integrally formed on the first housing and the second housing. There is a gap between the groove wall of the installation groove 300 and the washer 500. The avoidance grooves 310 are located at two corner parts on the same side of the washer 500. The width of the avoidance groove is sufficient for the first corner part to swing therein. At least one of the corner parts of the washer 500 is a first corner part 510. The first corner part 510 is located near the first housing 110 or the second housing 120 and rotates towards the direction where the first housing 110 or the second housing 120 is located when the washer 500 deflects slightly clockwise or counterclockwise. When the washer 500 deflects counterclockwise, its first corner part 510 is always in the avoidance groove 310 and there is always a gap between the first corner part 510 and the groove wall of the avoidance groove 310.

[0023] As Figure 3 shown in the figure, when the washer deflects slightly counterclockwise, the first corner part 510 rotates into the avoidance groove. Since the groove wall of the avoidance groove abuts against the side wall 540 of the washer, the rotation of the washer is restricted. At the same time, the first corner part never contacts the outer wall of the first housing. Therefore, the torque transmitted to the sharp corner of the washer can be avoided and reduced. Thus, the corner part of the washer will not directly act on the outer wall of the housing. The effect of improving the strength of the housing can be achieved by skillfully reducing the material instead of increasing the wall thickness. At the same time, even if the washer rotates due to torsion, its side will abut against the groove wall of the avoidance groove and the corner part cannot act on the outer wall. Therefore, there will be no white spots or damage.

[0024] Similarly, when the washer deflects slightly clockwise, the third corner part 530 enters the avoidance groove.

[0025] The inner wall of the avoidance groove 310 is a plane or an arc surface. Whether to adopt a plane or an arc surface depends on the processing technology. The depth of the avoidance groove is preferably such that when the corner part rotates, it cannot directly contact the corner part due to the abutment of the side.

[0026] There are two corner parts of the washer 500 close to the first housing or the second housing. One is the first corner part 510 and the other is the second corner part 520. The second corner part 520 rotates towards the direction away from the first housing 110 or the second housing 120 when the washer 500 deflects slightly clockwise or counterclockwise.

[0027] The groove wall of the installation groove located at the rear end of the loop conductive member 400 is formed by the inner wall 130 perpendicular to the first housing 110 or the second housing 120. This inner wall can be composed of half-walls respectively formed on the first housing and the second housing and joined together, or can be directly integrally formed on the first housing or the second housing. It is mainly used to bear the torsion generated when the tile gasket rotates. That is, when the first corner or the third corner rotates, it will abut against this inner wall, so that the inner wall bears the torsion, rather than causing the outer wall of the housing to bear the torsion.

[0028] Two corners are provided at the rear end of the tile gasket. The corner close to the first housing is the first corner 510, and the corner close to the second housing is the third corner 530. When the third corner 530 or the first corner 510 slightly deflects clockwise or counterclockwise on the tile gasket 500, it contacts the inner wall 130.

[0029] When the first corner rotates counterclockwise and the third corner also rotates accordingly, and it directly acts on the inner wall, with the inner wall bearing the torsion. Even if the torsion is continuously increased, the torsion will be transmitted to the interior of the product. At this time, the first corner of the tile gasket is still in a suspended state, and no force is applied to the outer wall of the product.

[0030] As Figure 1 As shown, the present utility model also discloses an auxiliary contact, which includes a housing 100 formed by the cooperation of a first housing 110 and a second housing 120. At least two pole cavities 200 are provided in the housing 100. A loop conductive member 400 is provided in the pole cavity 200. An installation groove 300 for placing a screw 600 and a tile gasket 500 is provided on the upper side of the loop conductive member 400. Static contacts are provided on the loop conductive member 400. A movable contact assembly 700 that can move axially is provided in the housing 100, and the movable contact assembly 700 can form a make-and-break cooperation with the static contacts. The tile gasket is rectangular. At least two avoidance grooves 310 are symmetrically provided on the groove wall of the installation groove 300. The avoidance grooves 310 are integrally formed on the first housing 110 and the second housing 120. There is a gap between the groove wall of the installation groove 300 and the tile gasket 500. The avoidance grooves 310 are located at two corners on the same side of the tile gasket 500. At least one of the corners of the tile gasket 500 is the first corner 510. The first corner 510 is located near the first housing 110 or the second housing 120, and rotates towards the direction where the first housing 110 or the second housing 120 is located when the tile gasket 500 slightly deflects clockwise or counterclockwise. When the tile gasket 500 deflects counterclockwise, its first corner 510 is always in the avoidance groove 310 and there is always a gap between it and the groove wall of the avoidance groove 310.

[0031] There are four pole cavities 200, which are respectively located on both sides of the movable contact assembly 700.

[0032] The circuit conductive members 400 are in two groups, with two in each group, and are arranged on both sides of the moving contact assembly 700 in layers. That is, the moving contact assembly includes a contact support and two groups of moving contacts arranged on the contact support. During operation, the two groups of moving contacts can respectively contact the circuit conductive members in the upper and lower layers to form a circuit.

[0033] The embodiments should not be regarded as limitations on the present utility model, but any improvements made based on the spirit of the present utility model should fall within the protection scope of the present utility model.
