Description

electrical connector

technical field

The utility model relates to an electric connector, in particular to an electric connector with many engaging places between conductive terminals and terminal holes.

Background technique

As various types of electronic products become more and more popular, the demand for electrical connectors, which are connecting components between electronic products, is also increasing. However, how to make the structure of the electrical connector capable of withstanding a large force of plugging and unplugging, and how to make the structure of the electrical connector not easily damaged after repeated plugging and unplugging is a common problem that the industry wants to solve.

A traditional plug-type electrical connector (plug connector), such as the electrical connector of US Patent No. US6,997,733, includes a rubber body and a plurality of conductive terminals, and the plurality of conductive terminals are inserted into the rubber core in the terminal hole of the body. Each conductive terminal has two horizontally protruding protrusions, and the width of the protrusions is greater than the width of the terminal hole of the rubber core body. Therefore, when the conductive terminal is inserted into the terminal hole, the two sides of the protrusion will abut against and press the hole surface of the terminal hole, so that an engaging force is generated between the two, and then the conductive terminal is fixed in the terminal hole. The engagement force between the terminal hole and the protrusion is determined by the interference amount between the width of the protrusion and the width of the terminal hole. The greater the interference amount, the greater the engagement force between the two, and the more stably the conductive terminal can be fixed on the terminal hole. in the terminal hole.

However, the conventional plug-type electrical connector often has the following disadvantages: the conductive terminal has only two protruding portions, and the force for the conductive terminal to engage with the terminal hole is only provided by the two protruding portions. If the designer wants to increase the engaging force between the conductive terminal and the terminal hole, the amount of interference between each protrusion and the terminal hole must be increased. The place where the terminal hole of the rubber core body is in contact with the convex part will also generate stress due to the engaging force. The structural strength of the rubber core body is usually low, and the stress it can withstand is relatively low, so the convex part and the terminal When the amount of hole interference is too large, the core body is easily damaged.

Therefore, when the conductive terminal has only two protruding parts, it is difficult to have a large engaging force between the plurality of conductive terminals and the terminal hole of the rubber core body.

Therefore, the utility model proposes an electrical connector with a reasonable design and which can effectively improve the above disadvantages.

Contents of the invention

The plurality of conductive terminals 20 are made of metal materials with high conductivity, which are sequentially inserted into the terminal holes 11 of the rubber core body 10, and the rear sides of the plurality of conductive terminals 20 protrude from the The rear side of the rubber core body 10 is outside.

3 and 4, each of the plurality of conductive terminals 20 has at least three horizontally protruding protrusions 21 and a plurality of vertically protruding protrusions 22, and each of the plurality of protrusions 21 is evenly distributed. On both sides of the plurality of conductive terminals 20 , the plurality of bumps 22 are disposed on the top surface or the bottom surface of the plurality of conductive terminals 20 , and can also be disposed on the top surface and the bottom surface of the plurality of conductive terminals 20 at the same time. In this embodiment, the plurality of bumps 22 are located on the top surface of the conductive terminal 20 , the number is six, and two bumps 21 are arranged on the top surface of each protrusion 21 .

Since the width of the plurality of protrusions 21 and the height of the protrusions 22 are larger than the corresponding size of the terminal hole 11, when the conductive terminal 20 is inserted into the terminal hole 11, the protrusions 21 and the protrusions 22 will be in contact with the terminal hole. 11 to form an interference fit, the plurality of protrusions 21 and bumps 22 will abut against and squeeze the hole surface of the terminal hole 11, so that an engaging force is generated between the two, and then the conductive terminal 20 is fixed in the terminal hole 11 .

In addition, the width of the protruding portion 21 closer to the front end of the conductive terminal 20 is slightly smaller than the width of the protruding portion 21 closer to the rear end of the conductive terminal 20. Such a design allows the assembler to insert the conductive terminal 20 into the terminal hole more easily. 11.

Since the plurality of conductive terminals 20 have more than three convex portions 21 and six convex points 22, there are nine places where the conductive terminals 20 engage with the terminal holes 11, each of which can provide a partial card. The resultant force is between the conductive terminal 20 and the terminal hole 11 , so the overall engaging force is much increased compared with the traditional design. Moreover, since the engaging force acts on the top surface and both sides of the plurality of conductive terminals 20 , the plurality of conductive terminals 20 can be more firmly fixed in the terminal hole 11 .

In addition, the engaging force provided by each convex portion 21 or protruding point 22 does not need to be too large, and the stress on the terminal hole 11 of the rubber core body 10 due to this force is also less, which can make the structure of the rubber core body 10 relatively small.
