Description

Technical Field

[0001] The utility model belongs to the technical field of fastener tools, in particular to an electric connector fastener installation tool. Background Art

[0002] When the circuit module is integrated into the whole machine, the circuit board will be installed in the shell for integrated protection, and then the electrical signal will be connected and transmitted with the outside through the electrical connector. The assembly of the electrical connector and the shell needs to be installed and fixed with the fasteners of the electrical connector to ensure that the circuit board, shell and electrical connector are integrated and will not shake to affect the connection and transmission of the electrical signal.

[0003] At present, the common micro rectangular electrical connector fasteners are round head internal slotted screws and fasteners. The screws have internal threads. Round head internal slotted screws can be assembled with a slotted screwdriver, and fasteners can be assembled with a hexagon socket. However, due to the limitations of the installation slots, the assembly space for fasteners is very small ( Figure 2 As shown in Figure 01), the hexagon socket does not have enough space to fit the fastener, making assembly difficult. The assembly efficiency is low when using open-end pliers, and there is a risk of damaging the housing and fasteners. When making a small open-end wrench for manual assembly, only a small angle can be turned during each assembly process, and the accuracy of aligning the outer edge of the fastener is poor each time, resulting in low assembly efficiency. When using an external thread mounting head for assembly, when the screw is tightened to a certain extent, there is a risk of thread damage and stripping.

[0004] Due to the limitations of the installation position, when the assembly space of the fasteners is very small, standard tools cannot complete the assembly efficiently and reasonably. It is necessary to design an electrical connector fastener installation tool for assembly. The external thread of the tool is pre-tightened first, and then tightened with an open-end wrench. This not only solves the problem of difficult assembly, but also significantly improves the assembly efficiency, while reducing the risk of damage. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an electric connector fastener installation tool, which can realize the assembly of fasteners in a small and limited installation space, improve the assembly efficiency and also increase the stability.

[0006] In order to solve the above technical problems, the technical solution of the utility model is: an electrical connector fastener installation tool, which includes: a tool body and a snap ring open wrench, the top of the tool body is a tightening handle, the middle from top to bottom is a cylinder, a hexagonal cylinder, and a stop end face, and the bottom is an external threaded installation head, the hexagonal snap ring of the snap ring open wrench is connected to the open wrench from the side through a connecting bracket, the outer diameter of the cylinder is smaller than the outer diameter of the tightening handle, and is also smaller than the circumscribed circle diameter of the hexagonal cylinder, the inscribed circle diameter of the hexagonal snap ring is larger than the outer diameter of the cylinder, and is inserted into the tool body and slides up and down in the cylindrical area, and the tool body and the snap ring open wrench form an integral whole.

[0007] In one embodiment, the fastener is a screw with an internal thread and an external hexagon socket (such as Figure 3 as shown).

[0008] In one embodiment, the external thread mounting head 105 is first connected to the internal thread of the fastener for pre-tightening.

[0009] In one of the embodiments, the hexagonal snap ring 201 can slide up and down between the cylinder 102 and the hexagonal column 103, and achieve torque transmission by sliding downward and clamping with the hexagonal column 103; at the same time, the stop end face 104 is used to prevent the hexagonal snap ring 201 from slipping, ensuring that the hexagonal snap ring 201 will not detach during the clamping process with the hexagonal column 103.

[0010] In one embodiment, the open-end wrench 203 is aligned with the outer edge of the fastener and the force is transmitted through the connecting bracket 202 to tighten the fastener.

[0011] In one embodiment, when the open-end wrench 203 is used to tighten the fastener, there is no space for tightening due to angle rotation. The open-end wrench 203 can be slid upward to change the angle and then tightened again.

[0012] In one embodiment, the external thread mounting head 105 is coaxial with the hexagonal retaining ring 201 and the open-end wrench 203. After the open-end wrench 203 changes its angle, it can quickly and accurately align with the outer edge of the fastener, thereby improving efficiency and accuracy.

[0013] The beneficial results achieved by the utility model are: the utility model provides an electrical connector fastener installation tool. When the fastener is small and cannot be assembled using a hexagonal socket due to limited installation space, the fastener can be assembled by cooperating with the patented external thread and open-end wrench, thereby solving the problem of difficult assembly, significantly improving assembly efficiency, and reducing the risk of shell scratches and fastener stripping due to tool mismatch during the assembly process. At the same time, the coaxial design of the external thread and the open-end wrench significantly improves the accuracy and efficiency of the open-end wrench in installing the fastener.

[0023] The utility model discloses an electric connector fastener installation tool, such as Figure 1 As shown, the tool comprises a tool body 10 and a snap ring open spanner 20. The fastener is pre-tightened using an external thread mounting head 105. At this time, the snap ring open spanner 20 is in a loose state and is not clamped with the hexagonal column 103 (combined with Figure 4 understand).

At this time, the fastener can be tightened by rotating the tightening handle 101 (combined with Figure 4 understand).

[0025] Further, when there is no space to tighten after rotating a certain angle, the snap ring open end wrench 20 is slid upward, rotated a certain angle, and then slid downward. According to the concentric and coaxial design, the open end wrench 203 can be quickly aligned with the outer edge of the fastener and then tightened. Repeat this process until the screw cannot be tightened and the assembly is completed (combined with Figure 4 understand).

[0026] Furthermore, after the assembly is completed, the snap ring open-end wrench 20 is first slid upward to disengage from the hexagonal column 103, and then withdrawn from the external thread installation head.

[0027] In summary, the utility model discloses an electric connector fastener installation tool, including a tool body and a snap ring open end wrench. The tool body is composed of a tightening handle, a cylinder, a hexagonal cylinder, a stop end face and an external thread installation head. The snap ring open end wrench is composed of a hexagonal snap ring, a connecting bracket and an open end wrench. The tool body can be first connected with the internal thread of the fastener for pre-tightening; then the hexagonal snap ring is clamped with the hexagonal cylinder of the tool body, and the open end wrench is aligned with the outer edge of the fastener, and the connecting bracket conducts force to tighten the fastener. The utility model proposes an electric connector fastener installation tool. In the case where the fastener is small and cannot be assembled using a hexagonal socket due to limited installation space, the fastener can be assembled by cooperating with the patented external thread installation head and the open end wrench, solving the problem of difficult assembly and reducing damage during the assembly process. At the same time, the concentric and coaxial design significantly improves the accuracy and efficiency of installation.
