Description

Technical Field

[0001] This utility model relates to the field of relay base technology, and more specifically, to an injection molded part for fixing a relay base. Background Technology

[0002] A relay is an electrical control device that, when a change in the input quantity reaches a specified requirement, causes a predetermined step change in the controlled quantity in the electrical output circuit. It establishes an interactive relationship between the control system and the controlled system. Commonly used in automated control circuits, it essentially converts a small current or low voltage signal into a large current or high voltage signal, thereby achieving circuit control. Therefore, it plays roles in automatic adjustment, safety protection, and circuit switching. When installing a relay, it is usually used in conjunction with a relay base.

[0003] When existing relay bases are used for a long time, wear and tear can reduce the secure installation of the relay, causing the live conductors of the connecting wires to detach from the relay base, resulting in poor contact and overheating, or even leakage when they come into contact with the metal casing, leading to circuit failure and inability to meet the needs of use. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a safe and reliable injection molded part for fixing a relay base.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a relay base fixing injection molded part, including a base body and a movable clip disposed at the bottom end of the base body. The base body has several evenly distributed connecting seats on both sides, the connecting seats being used to install gaskets, and the base body has several mounting seats in the middle for installing connecting pieces. The base has clips symmetrically disposed on both sides, the clips being disposed between the connecting seats and the mounting seats. Each clip includes connecting seats symmetrically disposed on both sides. The base has an assembly groove adapted to the clip. The connecting seat has a mounting groove in the middle of one side and a limiting groove symmetrically disposed on the other side. The connecting seat has a circular hole in the center.

[0006] The present invention is further configured such that the width of the mounting groove is between 1 / 2 and 2 / 3 of the width of the connecting seat.

[0007] The present invention is further configured such that: a protrusion is provided in the middle of the limiting groove, and the height of the protrusion is between 1 / 2 and 2 / 3 of the depth of the limiting groove.

[0008] The present invention is further configured such that: the mounting base includes a plurality of support columns with a bracket structure, a groove is provided between adjacent support columns, and inclined surfaces are provided on both sides of the upper end of the support column.

[0009] The present invention is further configured such that: the bottom end of the base body is provided with a sliding groove for mounting on the bracket, the movable clip is located on one side of the groove, and a number of limiting members are provided on the other side of the sliding groove.

[0010] The beneficial effects of this utility model are:

[0011] 1. The base body has several evenly distributed connecting seats on both sides, which are used to install gaskets. The base body also has several mounting seats in the middle for installing connecting pieces. Furthermore, symmetrical locking devices are arranged on both sides of the base, positioned between the connecting seats and mounting seats. Each locking device includes the symmetrically arranged connecting seats on both sides. The base also has assembly slots that mate with the locking devices, making assembly, maintenance, and disassembly very convenient. One side of the connecting seat has a mounting slot in the middle, and the other side has symmetrically arranged limiting slots. A circular hole is also provided in the center of the connecting seat, ensuring a better fit with the gasket. During installation, excessive torque will not cause damage, resulting in a more stable connection and extended service life.

[0012] 2. When the width of the mounting groove is less than half the width of the connector, the width of the corresponding washer bend also decreases. The torque generated when the nut connects to the washer will damage the bend and compromise the mounting structure. When the width of the mounting groove is greater than two-thirds the width of the connector, the torque generated when the nut connects to the washer will damage the mounting groove, preventing the wire from being securely fixed to the base. Therefore, a mounting groove width between half and two-thirds of the connector width ensures the structural strength of both the mounting groove and the washer bend.

[0013] 3. A protrusion is provided in the middle of the limiting groove to form a limiting structure, which restricts the gasket when it is installed on the connecting seat, making the connection more secure. When the height of the protrusion is less than 1 / 2 of the depth of the limiting groove, the length of the prongs on both sides of the bend on the corresponding gasket side becomes shorter, and the torque generated when the gasket is connected to the nut causes the gasket to detach from the connecting seat; when the height of the protrusion is greater than 2 / 3 of the depth of the limiting groove, the depth of the groove on the bend on the corresponding gasket side becomes deeper, reducing its structural strength and making it easier to damage during installation.

[0014] 4. The mounting base includes several bracket-shaped support columns that fit snugly against the connecting piece to form a support position. Grooves are provided between adjacent support columns to facilitate heat dissipation when connected to external circuits. Sloping surfaces are provided on both sides of the upper end of the support columns to facilitate fixing the connecting piece and prevent movement. The bottom of the base body has a sliding groove for mounting on the bracket. Movable clips are located on one side of the groove, and several limiting pieces are provided on the other side of the groove to facilitate fixing the base inside the electrical box and convenient maintenance and disassembly.

[0018] Reference Figures 1 to 2 The embodiments of this utility model will be further described below.

[0019] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0020] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0021] Figures 1 to 2 The diagram shows an injection-molded part for fixing a relay base, comprising a base body 1 and a movable clip 11 disposed at the bottom of the base body 1. The base body 1 has several evenly distributed connecting seats 2 on both sides, which are used to install gaskets. The base body 1 also has several mounting seats 3 in the middle for installing connecting pieces. Clips 12 are symmetrically arranged on both sides of the base, positioned between the connecting seats 2 and the mounting seats 3. Each clip 12 includes connecting seats 2 symmetrically arranged on both sides. The base has an assembly groove adapted to the clip 12. One side of the connecting seat 2 has an installation groove 8 in the middle and a symmetrically arranged limiting groove 6 on the other side. A circular hole 7 is provided at the center of the connecting seat 2, facilitating assembly, maintenance, and disassembly. The installation groove 8 on one side and the symmetrically arranged limiting groove 6 on the other side, along with the circular hole 7 at the center of the connecting seat 2, ensures a better fit with the gaskets, preventing excessive torque during installation and resulting in a more stable connection and extended service life.

[0022] When the width of the mounting groove 8 is less than half the width of the connector 2, the width of the corresponding washer bend also decreases. The torque generated when the nut connects to the washer will damage the bend and compromise the mounting structure. When the width of the mounting groove 8 is greater than two-thirds the width of the connector 2, the torque generated when the nut connects to the washer will damage the mounting groove 8, preventing the wire from being securely fixed to the base. Therefore, the width of the mounting groove 8 should be between half and two-thirds the width of the connector 2 to ensure the structural strength of both the mounting groove 8 and the washer bend.

[0023] A protrusion 5 is provided in the middle of the limiting groove 6, forming a limiting structure that restricts the gasket when it is installed on the connecting seat 2, making the connection more secure. When the height of the protrusion 5 is less than 1 / 2 of the depth of the limiting groove 6, the length of the prongs on both sides of the bend on the corresponding gasket side becomes shorter, and the torque generated when the gasket is connected to the nut causes the gasket to detach from the connecting seat 2. When the height of the protrusion 5 is greater than 2 / 3 of the depth of the limiting groove 6, the depth of the groove on the bend on the corresponding gasket side becomes deeper, reducing its structural strength and making it easier to damage during installation.

[0024] The mounting base 3 includes several support columns 4 with a bracket structure, which can fit snugly with the connecting piece to form a support position. Grooves are provided between adjacent support columns 4 to facilitate heat dissipation when connected to external circuits. The upper ends of the support columns 4 have inclined surfaces on both sides to facilitate fixing the connecting piece and prevent movement. The bottom of the base body 1 has a sliding groove 10 for mounting on a bracket. A movable locking piece 11 is located on one side of the groove, and several limiting pieces 9 are provided on the other side of the sliding groove 10. The base is elastically fixed to the mounting strip inside the electrical box by a spring device provided within the movable locking piece 11. The limiting pieces 9 prevent the base from falling off. When the base needs maintenance, simply move the movable locking piece 11 to detach the base.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
