Description

A kind of terminal-connecting means being connected with serial port socket

Technical field:

The present invention relates to a kind of terminal-connecting means being connected with serial port socket.

Background technology:

Now the controller of electric automobile has the nine kinds of needles serial port socket will be together with wire bonds when assembling, on serial port socket, be provided with nine kinds of needles pin, pin is cylindrical shape, and desirable welding is that lead-in wire is inserted in cylinder pin, add again tin welding, to guarantee the steadiness of welding.But at present there is following technical problem in the nine kinds of needles serial port socket of controller when welding: 1) the lead-in wire external diameter of welding equates with cylinder pin external diameter, because a cylinder pin will insert two lead-in wires simultaneously, cause a central lead-in wire to be difficult to insert the tube of pin, cause production efficiency low; Moreover pin distance is too little, due to two accesses together, so there will be solder joint huge, the contact point of weld is little, built on the sand, lack of standardization, and does not meet standard; 2) this kind of welding manner may cause rosin joint, not prison welding, the easy problem such as come off; 3) because solder joint is large, space is occupied greatly, causes existing controller insufficient space, covers in upper cover is squeezed in lead-in wire, is also that junction stress is concentrated and caused fracture and come off, and reduces the life-span of controller.

Summary of the invention:

The object of this invention is to provide a kind of terminal-connecting means being connected with serial port socket, it is easy to connect neat fast, and it is closely firm to connect, and steady quality, safety standard, take up room little.

The object of the invention is to be achieved by following technical proposals.

A kind of terminal-connecting means being connected with serial port socket, comprise terminal and the lead-in wire that is connected to terminal tails, the top of terminal is a hollow sleeve, in hollow sleeve the inside, arrange and patch cylinder, between sleeve and cylinder, form gap, cylinder is plugged into the sleeve pin the inside of serial port hub tail, hollow sleeve is wrapped in the outside of sleeve pin, the afterbody of terminal is with groove, wallboard in the both sides of groove, end the end of a thread of lead-in wire is fixed on groove the inside by soldering, or on end the end of a thread connecting line ear of lead-in wire, line ear is nested in groove, pin gets up two wallboards and the connection of line ear.

Sleeve described above is that the little rear end of front end is large, and cylinder is also that the little rear end of front end is large.

The front end of sleeve described above has otch.

Sleeve described above is cylinder cone, and cylinder is cone.

Described abovely in several sleeve pins and terminal outside, serial port hub tail, protective jacket is installed.

The afterbody of lead-in wire described above couples together two or many wires by double team terminal.

Insulating cement is coated in end the end of a thread of terminal described above, lead-in wire, line ear outside.

The front end of cylinder described above arranges chamfering.

The present invention compared with prior art, has following effect:

1) top of terminal of the present invention is a hollow sleeve, in hollow sleeve the inside, arrange and patch cylinder, between sleeve and cylinder, form gap, during installation, cylinder is plugged into the sleeve pin the inside of serial port hub tail, and hollow sleeve is wrapped in the outside of sleeve pin, makes firm and reliable connection, be difficult for getting loose, effective guarantee energising is difficult for being interrupted;

2) terminal of the present invention is a standard component, and volume is little, is directly plugged on the sleeve pin the inside of serial port hub tail, without welding, and rosin joint and the short circuit problem of therefore avoiding welding to bring, reliable in quality, and compare standard and neat, safe.

3) sleeve is that the little rear end of front end is large, cylinder is also that the little rear end of front end is large, cylinder is plugged into the sleeve pin the inside of serial port hub tail, sleeve pin is outwards expanded, but sleeve pin is wrapped up by the hollow sleeve of terminal all the time, sleeve pin outwards expands the hollow sleeve of terminal when outwards expanding, therefore, sleeve pin closely cooperates with cylinder and the sleeve of terminal all the time, connects more solid and reliable; The front end of the sleeve that terminal is hollow has otch, facilitates sleeve outwards to expand.

4) afterbody of terminal is with groove, the wallboard in the both sides of groove, and end the end of a thread of lead-in wire is nested in groove the inside, goes between and can rotate freely under the prerequisite of holding circuit path like this, has increased flexibility, has also solved the problem of local space deficiency; End the end of a thread of lead-in wire is fixed on end the end of a thread connecting line ear of groove the inside or lead-in wire by soldering, and line ear is nested in groove, and pin gets up two wallboards and the connection of line ear.

5) afterbody of lead-in wire couples together two or many wires by double team terminal, thereby simplified structure is electrically connected to two or many wires by a terminal and a lead-in wire.

6) insulating cement is coated in end the end of a thread of terminal, lead-in wire, line ear outside, is coordinated conducting position to award protection, plays and increases adhesion and have effect insulated from each other.
