Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and in particular to a vehicle heater connector. Background Technology

[0002] Currently, new energy vehicles are increasingly widely used in all aspects of social life, and the detailed technologies in new energy vehicles are becoming more and more perfect. However, there are still some shortcomings. The liquid heater connection terminal is a connector used in the liquid heating circulation system of new energy vehicles. This connector realizes the connection between the circuit board and the heating plate. In the existing technology, the connector is often connected to the circuit board by surface mount soldering. However, the surface mount end of the conductive sheet in this connector is set horizontally. This structural design is unstable, and the conductive sheet is prone to fatigue fracture at the connection stress position, which seriously affects the service life of the product. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a vehicle heater connector that is not prone to fatigue fracture, has a long service life, and has a good performance.

[0004] The technical solution adopted by this utility model to solve its technical problem is a vehicle heater connector, including a base and conductive sheets arranged side by side on the base. The base and the conductive sheets are integrally injection molded. The conductive sheets include a first connecting end and a second connecting end. The first connecting end is vertically inserted through the bottom end of the base, and the second connecting end is horizontally inserted through the side end of the base. The second connecting end is also provided with a Z-shaped structure, which is arranged outside the side end of the base.

[0005] The advantages of the above technical solution are as follows: By integrally injection molding the base and the conductive sheet, external moisture cannot enter through the gap between the conductive sheet and the base. The conductive sheet adopts a structure with a vertical first connecting end and a horizontal second connecting end. This design makes it less likely for the conductive sheet to detach from the base during insertion and removal, making it more reliable. Furthermore, by setting a "Z"-shaped structure on the second connecting end, the thermal stress generated during the power-on process can be dispersed to a larger area, thereby effectively preventing breakage. This results in a long service life for the conductive sheet, excellent performance, and a simple structural design.

[0006] Furthermore, the zigzag structure includes a top segment, a first side segment, and a second side segment. The first side segment and the second side segment are perpendicularly disposed on the left and right sides of the top segment, and the length of the second side segment is greater than the length of the first side segment.

[0007] The advantages of adopting the above technical solution are: both the first and second side sections of the Z-shaped structure are set vertically, thereby preventing the end of the second connection from tilting up, thus ensuring the contact area with the circuit board, stable surface mount connection, good power conduction effect, and the second side section is longer. This setting makes the conductive sheet with the Z-shaped structure more resistant to breakage, and the structural design is reasonable.

[0008] Furthermore, the zigzag shape also includes a first bottom segment, which is horizontally positioned and connected to the second side segment. The first bottom segment is patch-connected to the circuit board, and a positioning protrusion is provided on the lower end surface of the first bottom segment, while a U-shaped notch is provided on the right end surface of the first bottom segment.

[0009] The advantages of the above technical solution are as follows: the first bottom segment of the zigzag structure is used as the end segment of the second connection end to be connected to the circuit board. The overall structure of the second connection end is simple and reasonable and easy to form. By setting positioning protrusions and U-shaped notches, the fit between the first bottom segment and the circuit board is more accurate and the soldering is more secure.

[0010] Furthermore, the zigzag shape also includes a second bottom segment, which is horizontally arranged. One side of the second bottom segment is connected to the first connecting end, and the other side of the second bottom segment is connected to the first side segment. The front and rear end faces of the second bottom segment are symmetrically provided with protrusions, which are arranged at the connection between the first bottom segment and the first side segment.

[0011] The advantages of the above technical solution are: the second bottom segment of the zigzag structure is used to connect the first connecting end and the first side segment. The overall structure of the second connecting end is simple and reasonable and easy to form. By setting protrusions, the anti-breakage effect of the conductive sheet with the zigzag structure is better and the structural design is more reasonable.

[0012] Furthermore, a first protrusion and a second protrusion are respectively provided on the lower end surface and the upper end surface of the base. The first protrusion and the second protrusion are arranged in a group, and the first protrusion and the second protrusion are arranged corresponding to the conductive sheet.

[0013] The advantages of the above technical solution are: the setting of the first protrusion and the second protrusion makes the connection strength between the conductive sheet with the first connection end and the second connection end structure and the base body high.

[0014] Furthermore, a first rib is provided on the lower end surface of the seat, and the first rib is connected and cooperates with the first protrusion. A second rib is provided on the upper end surface of the seat, and the second rib is connected and cooperates with the second protrusion.

[0015] The advantages of adopting the above technical solution are: by setting the first rib and the second rib, the connection strength between the first protrusion, the second protrusion and the base is higher, thereby making the use of the conductive sheet more reliable.

[0016] Furthermore, the left and right ends of the base are provided with mounting ears, the mounting ears are provided with mounting parts made of hard metal, the mounting parts are provided with mounting holes, and the outer peripheral wall of the mounting parts is provided with a snap-fit ​​structure.

[0017] The advantages of the above technical solution are as follows: by setting a mounting part made of hard metal on the mounting ear, the fixing bolt will not deform the seat body after it is engaged with the mounting hole on the mounting part, thus ensuring the reliability of use. In addition, the installation stability of the mounting part is higher by setting a snap-fit ​​structure. Attached Figure Description

Obviously, the accompanying drawings described below are merely some embodiments of this utility model.

Furthermore, references to orientation only indicate the relative positional relationship between the components, not their absolute positional relationship.

[0025] Please see Figures 1 to 5 As shown, a vehicle heater connector includes a base 1 and conductive sheets 2 arranged side-by-side at intervals on the base 1. Three conductive sheets 2 are provided. The base 1 and the conductive sheets 2 are integrally injection molded. Each conductive sheet 2 includes a first connecting end 3 and a second connecting end 4. The first connecting end 3 is vertically inserted through the bottom end of the base 1, and the second connecting end 4 is horizontally inserted through the side end of the base 1. The second connecting end 4 also has a U-shaped structure, which is positioned outward relative to the side end of the base 1. In this structure, the base 1 and the conductive sheets 2 are integrally formed. The injection molding method prevents external moisture from entering through the gap between the conductive sheet 2 and the base 1. The conductive sheet 2 adopts a structure with a vertical first connecting end 3 and a horizontal second connecting end 4. This design makes it less likely for the conductive sheet 2 to detach from the base 1 during insertion and removal, making it more reliable. Furthermore, the Z-shaped structure on the second connecting end 4 disperses the thermal stress generated during the power-on process to a larger area, effectively preventing breakage. This results in a long service life, excellent performance, and a simple structural design for the conductive sheet 2.

[0026] In this example, the Z-shaped structure includes a top segment 5, a first side segment 6, and a second side segment 7. The first side segment 6 and the second side segment 7 are vertically arranged on the left and right sides of the top segment 5, and the length of the second side segment 7 is greater than the length of the first side segment 6. In the above structure, the first side segment 6 and the second side segment 7 in the Z-shaped structure are both set to be vertical, thereby preventing the end of the second connection end 4 from tilting up, thus ensuring the contact area with the circuit board, stable surface mount connection, and good power conduction effect. In addition, the second side segment 7 is longer. This setting makes the anti-breakage effect of the conductive sheet 2 with the Z-shaped structure better, and the structural design is reasonable.

[0027] In this embodiment, the Z-shaped structure also includes a first bottom segment 8, which is horizontally positioned and connected to the second side segment 7. The first bottom segment 8 is patch-connected to the circuit board, and a positioning protrusion 9 is provided on the lower end surface of the first bottom segment 8. A U-shaped notch 10 is provided on the right end surface of the first bottom segment 8. In this example, the first bottom segment 8 in the Z-shaped structure is used as the end segment of the second connecting end 4 and patch-connected to the circuit board. The overall structure of the second connecting end 4 is simple and reasonable and easy to form. By setting the positioning protrusion 9 and the U-shaped notch 10, the fit between the first bottom segment 8 and the circuit board is more accurate and the soldering is more secure.

[0028] In this embodiment, the Z-shaped structure also includes a second bottom segment 11, which is horizontally arranged. One side of the second bottom segment 11 is connected to the first connecting end 3, and the other side of the second bottom segment 11 is connected to the first side segment 6. Protrusions 12 are symmetrically arranged on the front and rear end faces of the second bottom segment 11, and the protrusions 12 are arranged at the connection between the first bottom segment 11 and the first side segment 6. In the above structure, the second bottom segment 11 in the Z-shaped structure is used to connect the first connecting end 3 and the first side segment 6. The overall structure of the second connecting end 4 is simple and reasonable and easy to form. By setting the protrusions 12, the anti-breakage effect of the conductive sheet 2 with the Z-shaped structure is better, and the structural design is more reasonable.

[0029] In this embodiment, a first protrusion 13 and a second protrusion 14 are respectively provided on the lower end surface and the upper end surface of the base 1. The first protrusion 13 and the second protrusion 14 are arranged in a group and are arranged corresponding to the conductive sheet 2. In the above structure, the arrangement of the first protrusion 13 and the second protrusion 14 makes the connection strength between the conductive sheet 2, which adopts the structure of the first connecting end 3 and the second connecting end 4, and the base 1 high.

[0030] In this example, the end of the first connecting end 2 is designed as a ring, which ensures sufficient contact and good conductivity.

[0031] In this embodiment, a first rib 15 is provided on the lower end surface of the base 1, and the first rib 15 is connected and cooperates with the first protrusion 13. A second rib 16 is provided on the upper end surface of the base 1, and the second rib 15 is connected and cooperates with the second protrusion 14. In the above structure, by setting the first rib 15 and the second rib 16, the connection strength between the first protrusion 13, the second protrusion 14 and the base 1 is higher, thereby making the use of the conductive sheet 2 more reliable.

[0032] In this example, mounting ears 17 are provided on both the left and right ends of the base 1. Mounting ears 17 are provided with mounting parts 18 made of hard metal. Mounting parts are provided with mounting holes 19, and the outer peripheral wall of mounting parts 18 is provided with a snap-fit ​​structure 20. In the above structure, because the mounting parts 18 made of hard metal are provided on the mounting ears 17, the fixing bolts will not deform the base 1 after they cooperate with the mounting holes 19 on the mounting parts 18, thus ensuring the reliability of use. Furthermore, by providing the snap-fit ​​structure 20, the installation stability of the mounting parts 18 is improved.

[0033] In this embodiment, the snap-fit ​​structure 20 can be a snap-fit ​​tooth formed circumferentially on the outer wall surface of the mounting member 18, and the snap-fit ​​tooth is arranged in two sets, one above the other, which makes the installation stability of the mounting member 18 higher.

It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
