Problems solved by technology

But at present, the nine-pin serial port socket of the controller has the following technical problems when welding: 1) The outer diameter of the welded lead wire is equal to the outer diameter of the cylindrical pin. Since one cylindrical pin needs to be inserted into two leads at the same time, As a result, it is difficult for one of the leads to be inserted into the cylinder of the pin, resulting in low production efficiency; moreover, the distance between the pins is too small, and because the two lead wires are connected together, there will be a large solder joint and a small contact point at the solder joint. Unstable, non-standard, and non-standard; 2) This welding method may lead to problems such as false welding, weak welding, and easy falling off; 3) Due to large solder joints and large space occupation, the existing controller has insufficient space. Covering the upper cover will squeeze the lead wires in, and the stress concentration at the connection will lead to fracture and fall off, and reduce the life of the controller

Embodiment Construction

[0034] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0035] like figure 1 and figure 2 As shown, the nine-pin serial port socket 5 includes a sleeve pin 51 positioned at the rear and a serial socket 52 positioned at the front, and a pin 53 is arranged in the serial socket 52, and the pin 53 is electrically connected to the sleeve pin 51. To connect, install nuts 54 on both sides of the serial port socket 5 .

[0036] like image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, a terminal connection device connected to a serial port socket includes a terminal 1 and a lead wire 2 connected to the tail of the terminal 1. The top of the terminal 1 is a hollow sleeve 11, and a connecting rod is arranged inside the hollow sleeve 11. The cylinder 12 is inserted, and a gap 13 is formed between the...

Abstract

The invention discloses a terminal connecting device in socket connection with a serial port. The terminal connecting device comprises a terminal (1) and a lead wire (2) which is connected on the tail part of the terminal (1), wherein a hollow sleeve (11) is arranged on the top of the terminal (1); a plugging post body (12) is arranged in the hollow sleeve (11); and a clearance is formed between the sleeve (11) and the post body (12). The terminal connecting device is convenient, fast, neat, safe and standard, and has close and firm connection, stable quality and small occupation space.

Description

Technical field: [0001] The invention relates to a terminal connection device connected with a serial port socket. Background technique: [0002] Now the controller of the electric vehicle has a nine-pin serial port socket to be welded together with the lead wire during assembly. The nine-pin pin is arranged on the serial port socket, and the pin is cylindrical. In the pin of the cylinder, tin soldering is added to ensure the stability of the soldering. But at present, the nine-pin serial port socket of the controller has the following technical problems when welding: 1) The outer diameter of the welded lead wire is equal to the outer diameter of the cylindrical pin. Since one cylindrical pin needs to be inserted into two leads at the same time, As a result, it is difficult for one of the leads to be inserted into the cylinder of the pin, resulting in low production efficiency; moreover, the distance between the pins is too small, and because the two lead wires are connecte...
