Description

Technical Field

[0001] The present application relates to the field of relay assembly, and more specifically to a push rod limiting structure. Background Art

[0002] Our company's previous push rod 30 structural design was that the end of the push rod 30 was only directly against the first connecting part 21, as shown in the setting method 2. However, during the installation process, this structure will require the push rod 30 to be installed separately, and this product is a small structure product, which leads to the push rod 30 being more likely to fall off during the installation process. Therefore, the end of the push rod 30 away from the first connecting part 21 is heavier, and the end close to the first connecting part 21 is lighter, which causes the push rod 30 to easily fall off the first installation groove 101, thereby making the probability of the installation process successful in one time lower, thereby affecting the assembly efficiency, and thus the push rod 30 structure needs to be improved.

[0024] Schematic push rod limit structure

[0025] refer to Figures 1 to 3 According to a preferred embodiment of the push rod limiting structure of the present invention, it should be noted that the structure of the push rod limiting structure is as follows Figure 3As shown, it includes a housing structure 10, which is used to place other components of an external relay, and one side of the housing structure 10 has a first mounting groove 101, and both side walls forming the first mounting groove 101 have a first notch 102, and both first notches 102 are connected to the first mounting groove 101. In addition, the housing structure 10 has a bottom groove 105, a second mounting groove 103 and a third mounting groove 104 on the side where the first mounting groove 101 is provided, and the second mounting groove 103 and the third mounting groove 104 are arranged opposite to each other and spaced apart by a predetermined distance, and the bottom groove 105 is located on the lower side of the second mounting groove 103, and are connected to the second mounting groove 103 and the third mounting groove 104. It should be understood by those skilled in the art that, Figure 3 The housing structure 10 has a first partition and a second partition on one side of the first mounting slot 101. The first and second partitions form the aforementioned second mounting slot 103 and third mounting slot 104. The side of the second partition facing away from the first partition is used to house the external relay frame, with the top of the frame resting against the bottom wall forming the bottom slot 105. Specifically, an L-shaped yoke 100 is also positioned within the third mounting slot 104, the top of which is secured to the top of the frame 200.

[0026] It should also be noted that the rod limiting structure also includes an armature 20, which has a first connecting portion 21 and a second connecting portion 22. The first connecting portion 21 is connected to the second connecting portion 22, and the first connecting portion 21 is perpendicular to the second connecting portion 22. Specifically, the second connecting portion 22 is arranged horizontally and is placed in the bottom groove 105. At the same time, the end of the second connecting portion 22 is facing the bottom of the skeleton 200. In addition, the first connecting portion 21 is placed in the second mounting groove 103, and the top of the first connecting portion 21 is also facing one of the first notches 102. In addition, the width of the second mounting groove 103 is greater than the thickness of the first connecting part 21, so that the first connecting part 21 can swing toward the corresponding first notch 102 or toward the second partition at a predetermined angle. That is, those skilled in the art should understand that the skeleton 200 is also provided with an iron core and a coil 300, and the top of the skeleton 200 is facing the yoke 100, and the top of the iron core is fixedly connected to the yoke 100, and the second connecting part 22 is facing the bottom of the iron core. When the relay is operating, the armature 2030 is close to the wall of the iron core 200 and will be directly adsorbed on the bottom of the iron core 200. At this time, the first connecting part 21 swings toward the corresponding first notch 102 at a predetermined angle.

[0027] It is worth mentioning that the push rod limiting structure also includes a push rod 30, one end of which passes through one of the first notches 102, the first mounting groove 101 and the other first notch 102 in sequence, and rests on the first connecting portion 21. It should be noted that our company's previous push rod 30 structural design was only for the end of the push rod 30 to directly rest on the first connecting portion 21, as shown in Figure 2. However, during the installation process, this structure requires the push rod 30 to be installed separately, and this product is a small-structure product, which results in the push rod 30 being more likely to fall off during the installation process. Therefore, the end of the push rod 30 away from the first connecting portion 21 is heavier, and the end close to the first connecting portion 21 is lighter, which results in the push rod 30 being easily detached from the first mounting groove 101, which in turn reduces the probability of the installation process being successful in one go, thereby affecting the assembly efficiency, and thus the push rod 30 structure needs to be improved.

[0028] Specifically, the top of the first connecting portion 21 also has a limiting groove 2101, both ends of the limiting groove 2101 are connected to the first mounting groove 101, and one side of the first connecting portion 21 also has a matching groove 2102, and the matching groove 2102 is opposite to the bottom wall of the second mounting groove 103 to match the structure of the wall there.

[0029] It should also be noted that the push rod 30 has an insertion portion 31 and an extrusion portion 32, the insertion portion 31 is connected to the extrusion portion 32, and one end of the insertion portion 31 passes through one of the first notches 102, the first mounting groove 101 and the other first notch 102 in sequence, and rests on the first connecting portion 21, and the extrusion portion 32 is located on the side of the first mounting groove 101 away from the first connecting portion 21, and the end of the insertion portion 31 facing away from the extrusion portion 32 also has a limiting protrusion 321, and the limiting protrusion 321 cooperates with the limiting groove 2101. Specifically, the width of the limiting protrusion 321 is greater than the width of the limiting groove 2101, that is, the limiting protrusion 321 is squeezed into the limiting groove 2101 by an external extrusion device, thereby limiting the position of the insertion portion 31. It should be noted that, as Figure 2 As shown, the static spring piece 500 and the dynamic spring piece 400 can be installed on the other side of the shell structure 10, and the end of the extrusion portion 32 away from the insertion portion 31 is configured to squeeze the dynamic spring piece 400 so that the dynamic spring piece 400 swings toward the static spring piece 500 by a predetermined angle.

[0030] In summary, the push rod limiting structure based on the embodiment of the present application is explained, which provides the push rod limiting structure with advantages such as the push rod is not easy to fall, easy installation, high practicality, and local rationality.

[0031] It is worth mentioning that in the embodiments of the present application, the push rod limit structure does not involve complex manufacturing processes and expensive materials, and is highly economical. At the same time, for manufacturers, the push rod limit structure provided by the present application is easy to produce and has low cost, which is more conducive to controlling production costs and further facilitating product promotion and use.
