The plug connector comprises a first insulation body and a first terminal contained in the first insulation body; the socket connector comprises a second insulation body and a second terminal containing in the second insulation body; the first terminal and the second terminal are both arranged in an array and a cross mode. Compared with prior art, the terminals of the electric connector combination of the utility model adopt array type arrangement, a plurality of traditional operations of the board to board plug and socket connector without any clamping or connection can be replaced, and accordingly, the arranging density of the terminals can be effectively improved, which is helpful for the microminiaturization of the electronic products; as the terminals are respectively arranged in a cross mode, the signal disturbance can be greatly decreased.

Description

The electric connector combination

[technical field]

The utility model relates to the combination of a kind of electric connector, refer in particular to a kind of being used for directly to connect daughter board and motherboard, and the Board-to-Board Electrical Connector that includes pin connector and socket connector makes up.

[background technology]

In active computer, be extensive use of the Board-to-Board Electrical Connector combination and directly connect daughter board and motherboard, and need not to use winding displacement or other servicing unit.Plate all is provided with board-like electric connector and is long and narrow relatively, and has two row's terminals and extend to arrange insulating body on it.And along with current densities trend of rising on the circuit board, connect two circuit boards and usually need more than electric connector combination.Past is for achieving this end, all earlier plural socket connector is clipped together, and then with the motherboard welding, and the pin connector of respective numbers is also clipped together and be welded on the daughter board, afterwards, motherboard and daughter board are electrically connected with docking of socket connector via plug.Yet, can not guarantee that like this connector of clipping together can be in sustained height, therefore when this type electric connector butt joint, its inner terminal has in various degree amount of interference and causes relatively poor signal to transmit.Moreover, electric connector clipped together take a lot of work and not convenient.Therefore, need the Board-to-Board Electrical Connector combination of a kind of Improvement type of design to reduce the influence that defective was caused of above-mentioned existing Board-to-Board Electrical Connector combination.

[summary of the invention]

The purpose of this utility model is to provide a kind of electric connector combination with socket and plug connector, the combination of this electric connector can replace most traditional plates to plate plug and socket connector and operation that need not any clamping connection, and can improve the arranging density of terminal.

The combination of the utility model electric connector comprises pin connector and socket connector, this pin connector comprises first insulating body and is located in the first terminal in this first insulating body, this socket connector comprises second insulating body and is located in second terminal in second insulating body, this the first terminal and second terminal are array and arrange, and all are staggered.

Compared with prior art, the terminal of the utility model electric connector combination adopts array to arrange, can replace most traditional plates to plate plug and socket connector and operation that need not any clamping connection, thereby can effectively improve the arranging density of terminal, help the microminiaturization of electronic product, and terminal all is staggered, and can significantly reduce signal and disturb.

[embodiment]

The utility model electric connector combination comprises pin connector 1 and socket connector 3, sees also Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, and this pin connector 1 comprises rectangle first insulating body 10 and is located in some the first terminals 20 in first insulating body 10.This first insulating body 10 is provided with some the first terminal grooves 12, insert for the first terminal 20, each the first terminal groove 12 two opposite sides extends upward and is provided with support portion 14, this support portion 14 roughly is Contraband shape, and opening is relative, to clamp the first terminal 20, avoid this first terminal 20 when pegging graft, to produce flexural deformation.On these first insulating body, 10 longwells roughly the centre position be provided with projection 16.This first terminal 20 is to be formed by the metal sheet punching out, and roughly be tabular, it is provided with first main body 22, this first main body 22 extension downwards is provided with first junction 24, to connect mutually with corresponding circuits plate (not drawing among the figure), and extension is provided with first projection 26 to both sides in these first main body, 22 bottoms, so that this first terminal 20 is fixed in first insulating body 10.This first terminal 20 is to take array to arrange (be on length and width two directions the first terminal number average more than two rows) in first insulating body 10, and whenever ranked first terminal 20 all be staggered (as shown in Figure 2, promptly adjacent row's corresponding terminal is not arranged in same row).

As Fig. 5, Fig. 6, Fig. 7 and shown in Figure 8, this socket connector 3 comprises rectangle second insulating body 30 and is located in some second terminals 40 in second insulating body 30.This second insulating body 30 is provided with some second terminal grooves 32, inserts for second terminal 40.Projection 16 in these second insulating body, 30 outside corresponding plug connectors 1 is provided with groove 34, to cooperate with this projection 16, socket connector 3 and pin connector 1 is accurately located.This second terminal 40 also is to be formed by the metal sheet punching out, and with the first terminal 20 vertical corresponding settings (promptly assembling back cross section is cross), it is provided with second main body 42, these second main body, 42 both sides stretch out and are provided with second projection 44, extend downwards and be provided with second junction 45, extend upward and be provided with and second main body 42, two arms 46 at grade, these arm 46 inboards inwardly convex with contact site 48 relatively, gap between this contact site 48 is less than the thickness of 20 main bodys 22 of the first terminal in the pin connector 1, thereby these the first terminal 20 main bodys 22 can firmly be inserted between the contact site 48 that is fixed in second terminal 40 during assembling, guarantee that two electric connectors electrically conduct (as shown in Figure 9).Accordingly, this second terminal 40 also is that array is arranged in second insulating body 30, and whenever ranked second terminal 40 all be staggered (as shown in Figure 6, promptly adjacent row's corresponding terminal is not arranged in same row).

Because terminal all is that array is arranged in the utility model electric connector combination, thereby operation that need not any clamping connection just can make terminal arrange very closely; Terminal all is staggered, and makes the part that overlaps between terminal less, disturbs thereby can significantly reduce signal, and this is particularly important in high frequency environment; The first terminal and second terminal insert back cross section approximate vertical, thereby can utilize the space more fully, can make terminal arrange closelyr, help the microminiaturization of electric connector combination; Terminal structure is simple, and processing is got up very convenient (only needing stamping procedure), so applicable to very accurate and microminiaturized application scenario.
