Description

Technical Field

[0001] The present invention relates to the field of circuit board assembly, and particularly to a positioning device for installing circuit board plug connectors. Background Art

[0002] In the design and manufacturing process of motorcycle start-stop control systems, the reliability and installation efficiency of circuit boards are crucial. The traditional circuit board plug connectors of motorcycle start-stop controllers are welded to the circuit board through pins. The welding method usually involves manually aligning the pins on the plug board with the copper foil on the circuit board and then performing welding installation. This method has the following disadvantages:

[0003] First, the installation efficiency is low: The traditional installation method usually requires manual alignment and welding, which is not only time-consuming but also prone to errors, especially when multiple plug connectors need to be welded.

[0004] Second, the positioning is inaccurate: During the manual installation process, the alignment of the plug connector with the circuit board often depends on the experience and skills of the operator, making it difficult to ensure that each plug connector can be accurately installed in place.

[0005] Third, the welding quality is unstable: The quality of manual welding is affected by various factors, including welding temperature, welding time, and the skills of the operator, which may lead to uneven and unreliable welding points. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] As Figure 1 - Figure 2A positioning device for installing plug connectors of a circuit board 14 as shown, comprising a positioning plate 1. A positioning groove 2 matching the circuit board 14 is provided on the positioning plate 1. The positioning groove 2 is a blind groove, and a first relief groove 3 and a second relief groove 4 are also provided in the positioning groove 2. First plug connector positioning grooves 5 and second plug connector positioning grooves 6 are respectively provided at the front side edges of the positioning plate 1, and third plug connector positioning grooves 7 are respectively provided at the rear side edges of the positioning plate 1. Pressing mechanisms are respectively connected to the left side edge and the right side edge of the positioning groove 2 of the positioning plate 1, and a support wall strip 8 is also provided on the side wall of the positioning groove 2.

[0022] The process of using the present utility model is as follows. When it is necessary to weld and connect the plug connectors to the circuit board 14, first position the circuit board 14. Specifically, during positioning, the circuit board 14 is positioned and connected into the positioning groove 2, and its edge is supported by the support wall strip 8. The components on the circuit board 14 are accommodated through the space enclosed inside the support wall strip 8, while the relatively large components such as the heat sink and capacitors on the circuit board 14 pass through the first relief groove 3 and the second relief groove 4. After the circuit board 14 is positioned, the circuit board 14 is pressed by the pressing mechanism. Finally, the three plug connectors are respectively placed in the three plug connector positioning grooves 2, and the welding contacts on them are welded. After the welding is completed, the circuit board 14 can be taken out.

[0023] Furthermore, the pressing mechanism includes a pressing plate 9. The pressing plate 9 includes a large end portion 10 and a small end portion 11, and a pressing screw 12 is connected to the large end portion 10. The pressing plate 9 of the present utility model is made of rubber material. The pressing plate 9 is respectively composed of the large end portion 10 and the small end portion 11. The tightness of the pressing plate 9 is adjusted by the pressing screw 12 to make it in a state where it can rotate and can be preliminarily pressed, ensuring the positioning accuracy and firmness after installation of the circuit board 14 during the installation process.

[0024] Furthermore, a first relief groove 3 and a second relief groove 4 are also provided in the positioning groove. Specifically, through the first relief groove 3 and the second relief groove 4, relatively large components such as the heat sink and capacitors on the circuit board 14 can be relieved, avoiding deformation caused by extrusion.

[0025] Furthermore, a taking groove 13 is provided on the side of the positioning plate 1 beside the positioning groove 2, and the taking groove 13 is communicated with the positioning groove 2. Through the setting of the taking groove 13, it is convenient for the operator to take the circuit board 14 from the side after the welding and installation of the plug connectors are completed, making it convenient to apply force.

[0026] Further, both the first relief groove 3 and the third relief groove are through grooves. Since the bottoms of the first plug connector and the third plug connector have a protrusion, in order to provide clearance for the protrusion and to enable the smooth placement of the plug connectors, both the first relief groove 3 and the third relief groove are through grooves. At the same time, when taking the circuit board 14, in order to maintain the balance of the pulling force, while pulling the circuit board 14 through the pulling groove 13, a pulling force can also be applied upward to the circuit board 14 through the through groove. In this way, the circuit board 14 will not shift when being taken.

[0027] Further, the width of the support wall strip 8 is 5-6 mm. Specifically, the support wall strip 8 of the present utility model cannot be set too wide. It only needs to support the edge of the circuit board 14, otherwise it will interfere with the components on the circuit board 14.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
