Put, top 111 and bottom 112 can also electrically connect with adjacent device respectively.The first terminal 11a top 111 and bottom 112
On can be provided with connecting hole 114, and connecting hole 114 can run through the first terminal 11a top along the thickness direction at top 111
Portion 111 and bottom 112；Can be provided with mounting hole 121 on insulating body 12, connecting hole 114 and mounting hole 121 can jointly with
Connector 2 coordinates, and electric connector 1 is connected together with adjacent device.The first terminal 11a and Second terminal 11b can be with
Be enclosed on insulating body 12, and make the first terminal 11a sidepiece 113 and Second terminal sidepiece 113 it is relative, meanwhile, can be with
All tops 111 and bottom 112 is set to be in contact with insulating body 12.
Wherein, the first terminal 11a and Second terminal 11b can made of same metal material electric-conductor, and the two
Shape and the size of corresponding position are also identical, and the first terminal 11a and Second terminal 11b can electrically connect with device, with
Make that between multiple devices the current loop closed can be formed.Certainly, the first terminal 11a and Second terminal 11b construction can also portions
Split-phase is same, and the metal material for such as making the first terminal 11a and Second terminal 11b can be different；The first terminal 11a and Second terminal
The size of the upper corresponding positions of 11b can also be of different sizes etc., but in order that caused inductance value is use up after electric connector 1 is powered
It is possible small, it is identical with Second terminal 11b it is advantageous to the first terminal 11a, and the structure of top 111 and bottom 112
It is identical.Below by taking the first terminal 11a as an example, in the first terminal 11a, top 111, bottom 112 and sidepiece 113 can be

Further, due to by the sense of current of top 111 and bottom 112 on the contrary, so top 111 and bottom 112 are being powered
In the case of caused inductance can cancel each other substantially；Likewise, due to the sidepiece 113 and second by the first terminal 11a
The sense of current of terminal 11b sidepiece 113 on the contrary, so, two sidepieces 113 inductance caused by because of energization also substantially can be with
Cancel each other.In summary, the electric connector 1 that the application provides, it can play a part of to electrically connect and support adjacent devices, also simultaneously
Itself can be mitigated because of energization and caused by inductance phenomenon.
Further, the electric connector 1 that the application provides can also include insulation board 13, and insulation board 13 can be connected to absolutely
On edge matrix 12, and insulation board 13 can be arranged at the first terminal 11a sidepiece 113 and Second terminal 11b sidepiece 113 it
Between.
Specifically, insulation board 13 can be the plate-like structures made of insulating materials such as rubber, plastics, mica.Wherein, it is excellent
Insulation board 13 and insulating body 12 is selected to be made up of same material, and insulation board 13 can be with insulating body 12 by integrally formed
Mode processes to be formed, and the insulation board 13 and insulating body 12 to link together can be such as processed by way of injection, and make
Insulation board 13 is located at the middle position of insulating body 12, can so make the first terminal 11a sidepiece 113 and Second terminal
11b sidepiece 113 can be respectively arranged at the relative both sides of insulation board 13, and make the first terminal 11a sidepiece 113 away from insulation board
13 distance, and distance of the Second terminal 11b sidepiece 113 away from insulation board 13 are generally equalized, and this can greatly reduce first
When passing to high current the probability of punch-through occurs for terminal 11a and Second terminal 11b；At the same time it can also make two sidepieces
113 in the case of energization caused inductance cancel out each other it is more thorough.
, can on insulating body 12 in order to further reduce the amount of the caused stray inductance when being powered of electric connector 1
To be provided with mounting groove 122, and the sidepiece 113 of the first terminal 11a sidepiece 113, insulation board 13 and Second terminal 11b can be according to
It is secondary to be distributed in mounting groove 122.
Specifically, mounting groove 122 can be bar-shaped trough, and in the manufacturing process of insulating body 12, can directly make
Insulating body 12 with mounting groove 122；It can also insulated after insulating body 12 completes, then by cutting tool etc.
The mounting groove 122 of bar shaped is processed on matrix 12.Certainly, mounting groove 122 can also be other suitable shapes and the groove of size.The
One terminal 11a sidepiece 113 and Second terminal 11b sidepiece 113 can be arranged in mounting groove 122, and this can make first end
Sub- 11a sidepiece 113 and Second terminal 11b sidepiece 113 are relatively near apart, and make the more compact structure of whole electric connector 1.Two
Individual sidepiece 113 is apart from each other compared to the two at a distance of relatively near, in the former two sidepieces 113 be powered caused by inductance can be more
Easily cancel out each other.
Optionally, on the distribution arrangement of all sidepieces 113, insulation board 13 can stretch in sidepiece 113 outside.Specifically, side
The distribution arrangement in portion 113 can be equal to two relative directions of sidepiece 113, it is also assumed that being two peaces on insulating body 12
Fill the line direction in hole 121, when manufacturing insulation board 13, can make that insulation board 13 has with sidepiece 113 and insulating body 12
Relative surface, the surface more relative with sidepiece 113 than on the surface of sidepiece 113 and insulating body 12 is bigger, can so make absolutely
Listrium 13 can separate the first terminal 11a and Second terminal 11b completely, i.e. be folded with insulation board 13 between two sidepieces 113,
This, which can be further reduced between the first terminal 11a and Second terminal 11b, the general of punch-through occurs because electric current is excessive
Rate；Meanwhile in the assembling process of electric connector 1 and adjacent devices, on insulation board 13 relative to the overhanging part of sidepiece 113 also
Pre-determined bit can be played, this can improve the efficiency of assembling of electric connector 1.
In order that the annexation between electric connector 1 and adjacent device is more stable, a kind of preferable specific embodiment
