Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to an electrical connection technical field, more particularly, it relates to an anti-disassembly insulator. BACKGROUND
[0002] Generally, in the process of pin assembly, due to the installation of two independent insulators, after the pin assembly, the insulator is prone to falling off and needs to be reinstalled, for the multi-core pin, the on-site installation difficulty is increased, meanwhile, in the wire welding process, the independence of the insulator causes the difficulty of wire welding.
[0003] Therefore, the design of the bayonet is used to fix the front and rear insulators. In the production operation process, the operator installs the pin on the insulator, and the two independent insulators are fixed together by using the buckle device on the front and rear insulators, so that the method of fixing by using adhesive tape is reduced, thereby ensuring the convenience of installation and wire welding. UTILITY MODEL CONTENTS
[0004] In view of the deficiencies in the prior art, the utility model aims at providing an anti-disassembly insulator which is firm in installation and convenient in disassembly.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: an anti-disassembly insulator, comprising a front insulating plate and a rear insulating plate, the end face of the rear insulating plate is symmetrically provided with buckles on both sides, the end face of the front insulating plate is provided with insertion grooves matched with the buckles on both sides, the bottom end of the insertion groove extends to the outer wall of the front insulating plate to form a bayonet, the top end of the buckle is provided with a barb, and the insertion groove is configured to form a clamping connection when the buckle is inserted, and the barb on the buckle is in abutment with the bayonet on the insertion groove.
[0006] The utility model is further provided as follows: the front insulating plate comprises a head end portion and a tail end portion, and the depth of the insertion groove is between 0.5 and 0.7 times the axial length of the head end portion.
[0007] The utility model is further provided as follows: the thickness of the barb is between 0.5 and 0.7 times the depth of the bayonet.
[0008] The utility model is further provided as follows: the width of the insertion groove is between 1.5 and 1.7 times the thickness of the buckle.
[0009] The utility model is further provided as follows: the rear insulating plate is provided with two mounting holes for mounting the pins, and the front insulating plate is provided with through holes corresponding to the mounting holes.
[0010] The utility model has the advantages of:
[0011] 1. When the buckle is inserted into the slot, the barb on the buckle and the socket on the slot are in contact to form a clamping connection, and the barb on the top end of the buckle and the socket on the slot are in contact to form a clamping connection. This structure makes the front and rear insulating plates not easy to accidentally separate after assembly, can reliably maintain the connected state, and the operation is relatively simple and direct, without the need for complex auxiliary tools or tedious installation process, which can improve the assembly efficiency, reduce the assembly difficulty, save manpower and time cost, and is especially suitable for batch assembly production scenes.
[0012] 2. When the depth of the slot is less than 0.5 times the axial length of the first end part, the slot is too shallow to cause the clamping connection to be not firm and easy to be separated under external force; when the depth of the slot is greater than 0.7 times the axial length of the first end part, the outer wall of the first end part becomes fragile and fragile because the slot is too deep, and the buckle matched with the slot is too long to be easily broken, therefore, the depth of the slot is between 0.5 to 0.7 times the axial length of the first end part, which effectively withstands external force from different directions and maintains the stability of the structure.
[0013] 3. When the thickness of the barb is less than 0.5 times the depth of the socket, the width of the barb is too narrow to cause the contact area with the socket to be too small, and the clamping connection is easy to loosen and separate; when the thickness of the barb is greater than 0.7 times the depth of the socket, the width of the barb is too wide to make the insertion process difficult or cause extrusion damage to the surrounding structure due to the size being too large, and it is also exposed outside the sidewall of the front insulating plate, affecting the appearance, therefore, the thickness of the barb is between 0.5 to 0.7 times the depth of the socket, which improves the smoothness of the assembly operation, reduces the possible jamming problems in the assembly process, and improves the assembly efficiency.
[0014] 4. When the width of the slot is less than 1.5 times the thickness of the buckle, the width of the slot and the buckle is close, causing difficulty in insertion or jamming, increasing the fault tolerance of the assembly operation; when the width of the slot is greater than 1.7 times the thickness of the buckle, it is easy to separate the clamping connection under the action of external force, making the connection structure unstable, therefore, the width of the slot is between 1.5 to 1.7 times the thickness of the buckle, the buckle can still move freely in the slot within this width range, ensuring the stability and reliability of the connection between the front and rear insulating plates, improving the assembly efficiency, the two mounting holes provided on the rear insulating plate provide a clear mounting position for the insertion pin, and the front insulating plate is provided with through holes corresponding to each mounting hole, providing a channel for the further extension of the insertion pin or connection with external lines, and the operation process is relatively clear and simple.

[0018] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to describe the relationship of one element or feature to another element or feature as shown in the drawings. It should be understood that, in addition to the orientation shown in the drawings, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the drawing is inverted, the element described as being "below" other elements or features will be positioned "above" the other elements or features. Therefore, the exemplary term "below" can include both upward and downward orientations. The device can be positioned in other ways (rotated 90 degrees or positioned in other orientations), and the spatial relative descriptions used herein can be interpreted accordingly.
[0019] Moreover, relational terms such as "first" and "second" and the like are used solely to distinguish one from another of a common entity without necessarily requiring or implying any such actual relationship or order between such entities.
[0020] As Figure 1 shown in the drawings, an anti-disassembly insulator includes a front insulating plate 10 and a rear insulating plate 1, the end face of the rear insulating plate 1 is symmetrically provided with a fastener 2 on both sides, the end face of the front insulating plate 10 is provided with an insertion slot 4 adapted to each fastener 2 on both sides, the bottom end of the insertion slot 4 extends to the outer wall of the front insulating plate 10 to form a bayonet 5, the top end of the fastener 2 is provided with an inverted hook 3, the insertion slot 4 is configured such that when the fastener 2 is inserted, the inverted hook 3 on the fastener 2 abuts against the bayonet 5 on the insertion slot 4 to form a clamping connection, when it is necessary to disassemble the front and rear insulating plates, only need to press the inverted hook 3 on the fastener 2 inward, and then move the rear insulating plate 1 outward, so that the front and rear insulating plates can be separated, this structure makes the front insulating plate 10 and the rear insulating plate 1 not easy to accidentally separate after assembly, can reliably maintain the connected state, the operation is relatively simple and direct, does not need to rely on complex auxiliary tools or tedious installation process, can improve the assembly efficiency, reduce the assembly difficulty, save the labor and time cost, especially suitable for batch assembly production scenes.
[0021] When the depth of the slot 4 is less than 0.5 times the axial length of the first end part 9, the slot 4 is too shallow to cause the clamping to be not firm and to be easily separated under the action of external force; when the depth of the slot 4 is greater than 0.7 times the axial length of the first end part 9, the outer wall of the first end part 9 becomes fragile and fragile because the slot 4 is too deep, and the fastener 2 matched with the slot 4 is too long to be easily broken, therefore, the depth of the slot 4 is between 0.5 to 0.7 times the axial length of the first end part 9, which effectively bears the external force from different directions and maintains the stability of the structure.
[0022] When the thickness of the barb 3 is less than 0.5 times the depth of the bayonet 5, the width of the barb 3 is too narrow to cause the contact area with the bayonet 5 to be too small, and the clamping is easily loose and separated; when the thickness of the barb 3 is greater than 0.7 times the depth of the bayonet 5, the width of the barb 3 is too wide to make the insertion process difficult or to cause extrusion damage to the surrounding structure due to the size being too large, and the barb 3 is also exposed outside the side wall of the front insulating plate 10, affecting the appearance, therefore, the thickness of the barb 3 is between 0.5 to 0.7 times the depth of the bayonet 5, which improves the smoothness of the assembly operation, reduces the possible jamming and other problems in the assembly process, and improves the assembly efficiency.
[0023] When the width of the slot 4 is less than 1.5 times the thickness of the fastener 2, the width of the slot 4 and the fastener 2 is close to cause the phenomenon of being difficult to insert or being stuck, which increases the fault tolerance of the assembly operation; when the width of the slot 4 is greater than 1.7 times the thickness of the fastener 2, it is easily separated from the clamping under the action of external force, so that the connection structure is unstable, therefore, the width of the slot 4 is between 1.5 to 1.7 times the thickness of the fastener 2, which ensures that the fastener 2 can still move freely in the slot 4 within this width range, guarantees the stability and reliability of the connection between the front and rear insulating plates 1, and improves the assembly efficiency.
[0024] The two mounting holes 7 provided on the rear insulating plate 1 provide a clear mounting position for the pin, and the front insulating plate 10 is provided with a through hole 8 corresponding to each mounting hole 7, which provides a channel for the further extension of the pin or connection with external lines, and the operation process is relatively clear and simple.
