Description

Technical Field

[0001] This utility model relates to a resistance welding carrier, specifically, to an insulation structure for a resistance welding carrier. Background Technology

[0002] Resistance welding is a process that uses the resistance heat generated by the current flowing through the contact area of ​​the workpiece to heat the metal to a molten or plastic state, and then applies pressure to achieve a fusion connection. In the production of straight male terminals, the conductor needs to be welded to the terminal by resistance welding. To ensure the stability of both during the welding process, the straight male terminal and the conductor usually need to be precisely placed in corresponding positions on a metal carrier beforehand.

[0003] However, traditional metal carriers have the following drawbacks: First, current can easily pass through the carrier, causing abnormal conduction, resulting in insufficient welding energy, poor weld quality, and damage and safety hazards caused by resistance heating. Second, the connection stability between insulating components and the carrier body is poor, and they are prone to loosening and displacement under long-term welding vibration and temperature cycling, leading to insulation failure. Moreover, conventional insulating materials are difficult to maintain reliable performance in the long-term welding environment of high temperature and high mechanical stress. Third, the insulation structure design often fails to take into account the precise positioning requirements and insulation requirements of the direct male terminal and the conductor, which makes them prone to misalignment during welding, affecting the consistency and stability of the welding. Utility Model Content

[0004] The purpose of this invention is to provide an insulation structure for resistance welding carriers to solve the problems mentioned in the background art. Traditional metal carriers have the defect that current can easily pass through the carrier and form abnormal conduction. This defect leads to insufficient welding energy, poor weld quality, and damage to the carrier and safety hazards caused by resistance heating effect.

[0005] To address the above problems, the present invention provides an insulating structure for a resistance welding carrier, including a carrier base. A lifting block and a conductor support plate are fixedly installed on the upper side wall of the carrier base. A gap is provided between the conductor support plate and the lifting block. An insulating block is fixedly installed on the upper side wall of the lifting block. A terminal support plate is horizontally arranged on the upper side wall of the insulating block. A positioning component for fixing the terminal support plate is provided on the insulating block. A plurality of straight male terminals are horizontally arrayed and fixedly connected on the upper side wall of the terminal support plate. A conductor is placed on the conductor support plate at a position corresponding to each straight male terminal. The ends of the conductors and straight male terminals that are close to each other extend directly above the gap, and the ends of the conductors contact the upper side wall of the corresponding straight male terminal ends.

[0006] As a further improvement to this technical solution, the positioning component includes two symmetrically arranged recessed grooves on the top of the raised block. A pad is provided on the bottom side inside the recessed groove, and a needle seat is provided on the upper side wall of the pad. The lower side wall of the insulating block contacts the upper side wall of the needle seat.

[0007] As a further improvement to this technical solution, a positioning pin is vertically arranged on the upper side wall of the pin holder. The positioning pin is integrally formed with the pin holder, and the upper end of the positioning pin slides through the insulating block and extends upward.

[0008] As a further improvement to this technical solution, the terminal carrier plate is provided with a number of positioning holes arranged in a horizontal array, and the two positioning pins pass through two of the positioning holes and extend upward.

[0009] As a further improvement to this technical solution, the positioning component also includes a pressure cap that is slidably sleeved on the positioning pin, and the lower sidewall of the pressure cap contacts the upper sidewall of the terminal support plate.

[0010] As a further improvement to this technical solution, a number of blocks are fixedly connected in a horizontal array at one end of the upper sidewall of the lifting block near the conductor bearing plate. A positioning groove is formed between two adjacent blocks. The positions of the positioning grooves correspond to the positions of a number of straight male terminals, and the straight male terminals are set inside the corresponding positioning grooves.

[0011] As a further improvement to this technical solution, a positioning block is fixedly installed on the upper side wall of the straight male terminal, and the two ends of the bottom of the positioning block are respectively in contact with the side of the stop block on both sides of the corresponding positioning groove that are close to each other.

[0012] As a further improvement to this technical solution, a long groove is provided on the conductor carrier plate at a position corresponding to each conductor, and the conductor contacts the inner wall of the corresponding long groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The insulation structure of this resistance welding carrier uses polyetheretherketone (PEEK) insulating blocks and conductor carrier plates as the core insulation barrier, supplemented by PEEK pads and positioning blocks for auxiliary isolation. At the same time, the design prevents the pin holder from contacting the inner wall of the embedded groove, which can effectively block the current path between the conductor and the straight male terminal and the metal carrier seat and lifting block, thereby avoiding damage to the carrier seat and lifting block due to heat generation and improving the safety of the welding process.

[0014] 2. The insulation structure of this resistance welding carrier has a pre-set gap between the lifting block and the conductor support plate, which provides space for downward deformation or displacement of the welding part where the conductor and the straight male terminal are in contact. When the conductor or the straight male terminal deforms due to vibration or thermal effect during the welding process, this gap allows them to make adaptive movements in the direction of the gap, buffering mechanical stress and preventing the insulation structure from loosening, shifting or failing due to stress.

[0015] 3. The insulation structure of this resistance welding carrier restricts the horizontal movement of the terminal support plate through the cooperation of the positioning pin and the positioning hole. The pressure cap uses gravity to press the terminal support plate to prevent it from falling upward. At the same time, the positioning groove cooperates with the inclined surface of the positioning block to restrict the movement of the positioning block and the straight male terminal in the horizontal and vertical directions. The groove is set on the conductor support plate to constrain the horizontal degree of freedom of the conductor. Through the synergistic effect of these positioning structures, the straight male terminal and the conductor are accurately and stably kept in the predetermined contact position during the welding process, thereby ensuring the alignment accuracy and welding quality of the welding point.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 Please see Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the purpose of this embodiment is to provide an insulating structure for a resistance welding carrier, including a carrier base 1. A lifting block 2 and a conductor carrier plate 5 are fixedly installed on the upper side wall of the carrier base 1. A gap is provided between the conductor carrier plate 5 and the lifting block 2. An insulating block 3 is fixedly installed on the upper side wall of the lifting block 2. A terminal carrier plate 4 is horizontally arranged on the upper side wall of the insulating block 3. Several straight male terminals 42 are horizontally arrayed and fixedly connected on the upper side wall of the terminal carrier plate 4. It should be noted that the terminal carrier plate 4 is composed of multiple sub-carrier plates bonded and spliced ​​together. Each straight male terminal 42 is fixed on the corresponding sub-carrier plate. A conductor 9 is placed on the conductor carrier plate 5 at the position corresponding to each straight male terminal 42. The ends of the conductor 9 and the straight male terminal 42 that are close to each other extend to the top of the gap, and the end of the conductor 9 contacts the upper side wall of the end of the corresponding straight male terminal 42.

[0020] Both the insulating block 3 and the conductor carrier plate 5 are made of polyetheretherketone (PEEK), a material with excellent insulation properties. This material maintains excellent electrical insulation performance and mechanical strength even under extreme high temperatures and harsh environments, making it very suitable for resistance welding applications. The core function of this insulation structure is to block the current flowing from the conductor 9 and the straight male terminal 42 to the carrier base 1 and the lifting block 2, thereby preventing damage to the carrier base 1 and the lifting block 2 due to abnormal energization and heating, and improving the safety of the welding process.

[0021] The contact point between conductor 9 and straight male terminal 42 is the welding point. When the external welding torch welds this welding point from top to bottom, the welding point is located directly above the gap, providing space for the conductor 9 and straight male terminal 42 to deform or shift downwards during the welding process. If the conductor 9 and straight male terminal 42 deform due to factors such as vibration or temperature changes during the welding process, they can make adaptive displacements towards the gap direction, thereby effectively buffering the mechanical stress they are subjected to. This design avoids loosening or displacement of conductor 9, straight male terminal 42, insulating block 3, and conductor carrier plate 5 due to stress, thereby preventing insulation failure.

[0022] To improve the stability of the straight male terminal 42 during the welding process, a positioning assembly for fixing the terminal carrier plate 4 is provided on the insulating block 3. The structure of the positioning assembly is detailed below, referring to... Figure 2 and Figure 3 The positioning component includes two symmetrically arranged recessed grooves 21 on the top of the lifting block 2. A pad 6 is provided on the bottom side inside the recessed groove 21. A needle seat 7 is provided on the upper side wall of the pad 6. The lower side wall of the insulating block 3 contacts the upper side wall of the needle seat 7. The insulating block 3 and the lifting block 2 cooperate to fix the position of the needle seat 7.

[0023] A positioning pin 71 is vertically arranged on the upper side wall of the pin holder 7. The positioning pin 71 is integrally formed with the pin holder 7. The outer diameter of the positioning pin 71 is smaller than the outer diameter of the pin holder 7. The upper end of the positioning pin 71 slides through the insulating block 3 and extends upward. Several positioning holes 41 are arranged in a horizontal array on the terminal support plate 4. Two positioning pins 71 pass through two of the positioning holes 41 respectively and extend upward. The positioning assembly also includes a pressure cap 8 that is slidably sleeved on the positioning pin 71. The lower side wall of the pressure cap 8 contacts the upper side wall of the terminal support plate 4. In use, a metal pressure block is placed on the upper side wall of the lifting block 2. The two ends of the pressure block are fixed on the carrier seat 1. The pressure block presses down on the pressure cap 8 and presses it downward, so that the pressure cap 8 presses the terminal support plate 4 tightly.

[0024] The pin holder 7 and the positioning pin 71 are made of metal to ensure sufficient structural strength. The two positioning pins 71 and the two positioning holes 41 restrict the horizontal movement of the terminal support plate 4. The pressure cap 8 prevents the terminal support plate 4 from coming off vertically upward from the positioning pins 71, thereby fixing the terminal support plate 4 horizontally and stably above the lifting block 2.

[0025] To further enhance the stability of the terminal support plate 4, several blocks 22 are horizontally arrayed and fixedly connected to one end of the upper sidewall of the lifting block 2 near the conductor support plate 5. A positioning groove is formed between two adjacent blocks 22. The positions of the positioning grooves correspond to the positions of several straight male terminals 42. The straight male terminals 42 are set inside the corresponding positioning grooves. A positioning block 43 is fixedly installed on the upper sidewall of the straight male terminal 42. The two ends of the bottom of the positioning block 43 are in contact with the side of the blocks 22 on both sides of the corresponding positioning groove. The contact surface between the blocks 22 and the positioning block 43 is designed as an inclined surface. This structure restricts the downward and horizontal movement of the positioning block 43, thereby stabilizing the positioning block 43 and the straight male terminal 42 in the predetermined position in the positioning groove. At this time, the lower surface of the straight male terminal 42 is not in contact with the lifting block 2.

[0026] At the same time, the pressure block contacts the upper side wall of the positioning block 43, ensuring that the metal pressure block does not directly contact the straight male terminal 42, avoiding damage to the pressure block due to abnormal power supply and heating, and further improving welding safety.

[0027] In summary, the precise positioning of the terminal support plate 4 is achieved through the coordinated action of the positioning groove formed by the positioning component and the stop block 22 and the positioning block 43. This not only ensures that the welding position of each straight male terminal 42 can make precise contact with the corresponding conductor 9, but also improves the stability of the straight male terminal 42 during the welding process.

[0028] The pad 6, pressure cap 8, and positioning block 43 are all made of insulating polyetheretherketone material. The pin seat 7 does not contact the inner wall of the recessed groove 21. Therefore, the insulating pad 6 and insulating block 3 isolate the positioning pin 71, pin seat 7 from the lifting block 2. At the same time, the insulating block 3 and positioning block 43 also isolate the terminal support plate 4 and straight male terminal 42 from the lifting block 2. Therefore, the lifting block 2 can be made of metal to ensure its structural strength. The terminal support plate 4 and straight male terminal 42 will never form a conductive circuit with the carrier seat 1 and the lifting block 2.

[0029] To improve the stability of conductor 9 during the welding process, a long groove 51 is provided on the conductor support plate 5 at a position corresponding to each conductor 9. The conductor 9 contacts the inner wall of the corresponding long groove 51. The long groove 51 restricts the horizontal movement of conductor 9 in the direction perpendicular to its length, thereby enhancing the positioning stability of conductor 9.

[0030] In summary, by improving the stability of conductor 9 and straight male terminal 42 during the welding process, the welding quality between the two can be guaranteed.
