Abstract
Description
Technical Field
[0001] This utility model relates to the field of relay technology, and in particular to a hook structure and a relay. Background Technology
[0002] A relay is an automatic switching element that uses electromagnetic force to drive the movement of mechanical parts. It generally includes a base and a magnetic circuit section, a moving contact, and a stationary contact mounted on the base. When energized, the magnetic circuit section generates electromagnetic force to drive the moving and stationary contacts to close or open. The magnetic circuit section includes an armature and a yoke. The armature is oscillating relative to the yoke, allowing it to reciprocate between the closed and open positions of the contacts. Therefore, the armature has a certain amount of room to move relative to the yoke. To ensure this range of motion, a hook is provided on the base to pre-position the armature.
[0003] In the prior art, when the hook is installed on the base, the hook only has a plate-shaped mounting position that is connected to the base. When the hook is installed on the base, there is little area available for holding and installation, which reduces operability and makes installation difficult. Utility Model Content
[0004] To address at least one problem existing in the prior art, according to one aspect of the present invention, a hook structure is provided, comprising:
[0005] The plug-in portion includes a first plug-in segment, a connecting segment, and a second plug-in segment connected in sequence, wherein the first plug-in segment and the second plug-in segment are respectively inserted into the base;
[0006] The abutting portion is set at an angle to the first insertion section and is used to abut against the armature to apply a preload to the armature.
[0007] In some embodiments, the abutting portion includes a first abutting section and a second abutting section arranged at an obtuse angle, the first abutting section abutting against the armature, and the second abutting section being connected to the first insertion section.
[0008] In some embodiments, the included angle θ between the first abutment segment and the second abutment segment is in the range of 90° < θ ≤ 180°.
[0009] In some implementations, along the Z direction, the length of the first plug segment is greater than the length of the second plug segment.
[0010] In some embodiments, along the Z direction, the first plug segment includes a first part and a second part, the width of the first part along the Y direction is greater than the width of the second part along the Y direction, the second part connects to the connecting segment, and the abutting portion is connected to the end face of the first part facing the second part.
[0011] In some embodiments, the second part has the abutting portion on both opposite sides along the Y direction.
[0012] In some embodiments, the sidewall of the end of the first plug segment away from the connecting segment is inclined toward the center of the first plug segment.
[0013] In some embodiments, the second plug segment has a protrusion on at least one side along the Y direction, the protrusion being used to engage with the base, and the sidewall of the end of the protrusion away from the connecting segment is inclined toward the center of the second plug segment.
[0014] In some embodiments, the second plug segment has a rib on the side opposite to the first plug segment, and the rib is used to engage with the base.
[0015] In another aspect, this utility model provides a relay including the hook structure described above.
[0016] In summary, the hook structure and relay provided by this utility model have the following technical effects:
[0017] The armature is supported by the abutting part and the armature, and has a preload. When installed on the base, it is installed by inserting the insert part into the base. Since the insert part includes three parts: the first insert section, the connecting section and the second insert section, the overall structure is more complex, with more areas available for holding and installation, making it more maneuverable and easier to install.

Detailed Implementation
[0024] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.
[0025] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0027] The present invention will now be described in further detail with reference to the accompanying drawings.
[0028] Please see Figures 1 to 5 The hook structure 100 provided in this embodiment of the utility model includes a plug-in portion 10 and a holding portion 20.
[0029] The insertion part 10 is inserted into the base 200 and includes a first insertion section 11, a connecting section 12 and a second insertion section 13 connected in sequence along the X direction. The first insertion section 11 and the second insertion section 13 are respectively inserted into the base 200. The abutting part 20 and the first insertion section 11 are arranged at an angle to abut against the armature 300 to apply a preload to the armature 300.
[0030] The hook structure 100 mentioned above supports the armature 300 by abutting the abutting part 20 against it, and has a preload. When installed on the base 200, it is installed by inserting the insertion part 20 into the base 200. Since the insertion part 20 includes three parts: the first insertion section 11, the connecting section 12, and the second insertion section 13, the overall structure has more parts, more areas that can be used for holding and installation, stronger controllability, and is easier to install.
[0031] Understandably, since the first insertion segment 11 and the second insertion segment 13 need to be inserted into the base 200, in order to ensure the stability of the insertion, the first insertion segment 11 and the second insertion segment 13 are arranged parallel to each other and are inserted into the base 200 in the same insertion direction. When setting the connecting segment 12, the connecting segment 12 can be inclined to the first insertion segment 11 and the second insertion segment 13 respectively, that is, it has an acute angle and an obtuse angle with the first insertion segment 11 and the second insertion segment 13 respectively, or the connecting segment 12 can be perpendicular to the first insertion segment 11 and the second insertion segment 13 respectively, so that when the insertion part 10 is inserted into the base 200, the base 200 can have a regular shape during molding, and after installation, the connecting segment 12 can be exposed on the surface of the base 200.
[0032] Further, please refer to Figure 1 and Figure 2 When the first insertion segment 11 and the second insertion segment 13 are installed, along the Z direction, the length of the first insertion segment 11 is greater than the length of the second insertion segment 13. That is, when inserted into the base 200, the depth of the first insertion segment 11 inserted into the base 200 is greater than the depth of the second insertion segment 13 inserted into the base 200. This allows the entire hook structure 100 to be installed by first inserting the longer first insertion segment 11 into the base 200 as a positioning function, and then gradually installing the supporting part 20 and the second insertion segment 13 into place, which facilitates the installation of the hook structure 100.
[0033] Please see Figure 1 When the abutment portion 20 is provided on the first insertion segment 11, the first insertion segment 11 includes a first part 111 and a second part 112 along the Z direction. The width of the first part 111 along the Y direction is greater than the width of the second part 112 along the Y direction. The abutment portion 20 is connected to the end face of the first part 111 facing the second part 112. The end of the second part 112 away from the first part 111 is connected to the connecting segment 12. Thus, the first part 111 is set wider, which not only has a larger contact area with the base 200 and increases the stability of the connection with the base 200, but also, since the width of the first part 111 is greater than the width of the second part 112, a notch 113 is formed at the connection between the first part 111 and the second part 112, so that the abutment portion 20 can be provided at the notch 113.
[0034] Understandably, when the entire hook structure 100 is formed, the original state can be plate-shaped, and the plate is cut to obtain the first part to be bent. The first part to be bent and the second part 112 have a certain gap. The first part to be bent is bent to obtain the supporting section. Then the part connected to the second part 112 is bent to obtain the connecting section 12 and the second insertion section 13.
[0035] Furthermore, when setting the first part 111 and the second part 112, both sides of the first part 111 protrude from the second part 112 along the Y direction. That is, there are two notches 113 between the end face of the first part 111 facing the second part 112 and the second part 112. In order to ensure the preload force on the armature 300, the hook structure 100 includes two abutting parts 20. The second part 112 has abutting parts 20 on both opposite sides along the Y direction. That is, the hook structure 100 and the armature 300 have two support points, so that the pressure applied by the armature 300 to the abutting parts 20 is dispersed, ensuring the service life of the abutting parts 20.
[0036] Please see Figure 1 In one embodiment of this utility model, since the first insertion segment 11 needs to be inserted into the base 200, in order to improve the convenience of insertion, the side wall of the end of the first insertion segment 11 away from the connecting segment 12 is inclined towards the center of the first insertion segment 11. That is, the first insertion segment 11 is provided with a first inclined side wall 114. Specifically, the first inclined side wall 114 is provided at the end of the first part 111 away from the second part 112. The first inclined side wall 114 is provided to guide when inserted into the base 200, which facilitates the insertion operation.
[0037] Understandably, the first inclined sidewall 114 is provided on both sides of the first part 111 along the Y direction.
[0038] Further, please refer to Figure 1To ensure the stability of the entire hook structure 100 when inserted into the base 200, the second insertion segment 13 has a protrusion 131 on at least one side along the Y direction. The protrusion 131 is used to engage with the base 200, and the side wall of the end of the protrusion 131 away from the connecting segment 12 is inclined towards the center of the second insertion segment 13, which is equivalent to the protrusion 131 having a second inclined side wall 132. By setting the protrusion 131, after the second insertion segment 13 is inserted into the base 200, the protrusion 131 and the base 200 abut against each other, preventing the second insertion segment 13 from coming out of the base 200. Furthermore, compared with the prior art... The existing hook structure has only one mounting plate with a protrusion that plugs into the base 200. When the hook structure is installed on the base 200, the mounting plate is prone to deformation due to the compression between the protrusion and the base 200. Furthermore, a second inclined sidewall 132 is provided on the protrusion 131 to guide the insertion of the second insertion segment 13, avoiding the increase in insertion difficulty when the protrusion 131 is provided. It is equivalent to the protrusion 131 in this embodiment having a "barb" structure, which is an interference fit with the base 200 and is tightly hooked into the base 200, improving the stability of the insertion.
[0039] In addition, please see Figure 1 and Figure 2 To further enhance the stability of the entire hook structure 100 when inserted into the base 200, a rib 133 is provided on the side of the second insertion segment 13 facing away from the first insertion segment 11 along the X direction. The rib 133 is used to engage with the base 200, which is equivalent to an interference fit, thus increasing the stability of the insertion. Understandably, by providing the rib 133 on the second insertion segment 13, the two opposing planes of the first insertion segment 11 become complete planes. When inserted into the base 200, this serves a positioning function. However, compared to providing the rib 133 on the first insertion segment 11 (which is equivalent to providing a rib on the mounting plate in the prior art), this method could easily cause the first insertion segment 11 to deform. Therefore, the rib 133 and the protrusion 131 on the second insertion segment 13 can prevent deformation of the hook structure 100 when installed on the base 200.
[0040] Furthermore, in order to facilitate the insertion of the second insertion segment 13 into the base 200, the head of the protruding rib 133 along the Z direction has an arc-shaped portion, which can be smoothly inserted into the base 200.
[0041] Understandably, in this embodiment, protrusions 131 and ribs 133 can be provided on the second insertion segment 13, or only one can be provided, both of which can achieve the effect of increasing the stability of the insertion part 10 when inserted into the base 200.
[0042] Please see Figure 2 The diagram below shows the structure of the supporting portion 20 in this embodiment. The supporting portion 20 includes two parts: a first supporting section 21 and a second supporting section 22 set at an obtuse angle. The first supporting section 21 supports the armature 300, and the second supporting section 22 is connected to the first insertion section 11. Thus, the first supporting section 21 and the second supporting section 22 set at an obtuse angle are equivalent to the first supporting section 21 moving closer to the first insertion section 11, which can adapt to the rotation of the armature 300 and form a small rotation space for the armature 300 to avoid rotation.
[0043] In some embodiments, the included angle θ between the first abutment segment 21 and the second abutment segment 22 is in the range of 90° < θ ≤ 180°. For example, θ can be set to values such as 90°, 120°, 150°, 160°, 165°, 170°, 175°, and 180° to achieve support for the armature 300.
[0044] For a schematic diagram of the cooperation between the hook structure 100 and the armature 300 in this embodiment, please refer to [link / reference needed]. Figures 3 to 5 .
[0045] The aforementioned relay, by configuring the abutment portion 20 to include a first abutment section 21 and a second abutment section 22 arranged at an obtuse angle, can be adapted to the movement of the armature 300; by providing a rib 133 and / or a protrusion 131 on the second insertion section 13, the second insertion section 13 and the base 200 can be installed in an interference fit manner, increasing the installation stability of the entire hook structure 100 on the base 200, and at the same time preventing the first insertion section 11 in the insertion portion 10 from deforming when inserted into the base 200, thus affecting the pre-tightening effect of the abutment portion 20.
[0046] In another embodiment, the present invention also provides a relay, including the hook structure 100 described above.
[0047] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
