The utility model relates to a kind of connector, specifically, relates to a kind of electric connector that is used for the anti-mis-insertion of electronics, electrical system codified.

Range of application

Electric connector is widely used in fields such as electric power, electrical equipment, communication, railway, aviation, instrument and meter, machinery control, shipping industry.

Electric connector is to be used for the termination conductor, and plug together with respective element pairing or separate, to realize the element of connecting and disconnecting of the circuit, electric connector be realizations such as lead in the circuit, cable and components and parts be switched on or switched off fast make things convenient for element, in electric wiring, play the mechanical function effect, and circuit is connected or separation, circuit energy or signal are produced distribute and transmission.

The background that produces

In electric wiring, in most cases, can use a lot of electric connectors.These electric connector great majority have prevents self anti-inserted function, but the electric connector that does not still have anti-mis-insertion between same model occurs, these electric connector structures are identical, but the pairing electric logical relation of their contact pilotage has nothing in common with each other requirement formation one-to-one relationship when therefore plugging together.

The distribution personnel are when distribution, because of error might be with the electric connector wrong plug.In addition, the commissioning staff may carry out by subdivision when carrying out the whole set equipment debugging, and at this moment, the commissioning staff may withdraw from other unit, just removes the electrical connection of other unit, and its measure is exactly that relevant electric connector is pulled out.After unit accent passes to, the commissioning staff can plug together other electric connector, at this moment can produce the possibility of wrong plug electric connector, in other words this plug to electric connector is inserted on another socket to electric connector, so not only electric logical relation mistake, and may cause that components and parts burn, system crash, or even fatal crass's consequence, this problem allows circuit design engineer and engineering debug personnel have a headache especially, and therefore, development anti-mis-insertion electric connector is most important.

Structure and principle

At the problem of above-mentioned existence, task of the present utility model is to create the electric connector of a class codified, by the plug of electric connector, the encoding block on the socket are encoded, to reach the purpose that prevents the electric connector wrong plug.

Describe the principle of structure, coding and the anti-mis-insertion of this kind electric connector in detail below in conjunction with accompanying drawing.

Electric connector You plug of the present utility model, socket two large divisions Zu become, such as Fig. 1 Zhi is shown in Figure 8, plug You plug encoding block (1), plug plastic body (2), plug sun Contact pilotage (3) Zu becomes; Socket You socket encoding block (4), socket plastic body (5) is inserted Cloudy contact pilotage (6) Zu of Zuo becomes. The two sides that it is characterized in that the Zai plug are provided with quantity one Calmly be equipped with the encoding block (1) of numeral number on it, each encoding block of plug is Yu the plug basis The continuous position of body is processed with the groove (7) of the You certain depth of being convenient to Bai Zhe; Zai socket two The position corresponding Yu the encoding block of plug, side is provided with quantity equally Yu the plug coding The identical encoding block (4) that is equipped with numeral number on it of piece, each encoding block Yu of socket inserts The continuous position of seat body is processed with the groove (7) of the You certain depth of being convenient to Bai Zhe.

When electric connector is not encoded, that is to say and do not remove corresponding encoding block, Plug and socket just can not plug together, and corresponding cloudy contact pilotage just can't contact with positive contact pilotage; When When encoding, if the numbering of plug and socket is identical, removes in other words or keep and insert Behind the encoding block on head and the socket, the encoding block that stays on the socket just can be filled up corresponding being gone The remaining breach of the encoding block that falls, Zhe sample just can guarantee that plug and socket plugs together smoothly, Incorrect if encode, that is to say on the socket encoding block can not with encoding block on the plug Left breach is corresponding, encoding block just takes place on the plug on the encoding block and socket mutually The top, Zhe sample plug and socket just can not plug together, and prevents the effect that misplugs thereby just reached.

The encoding block of electric connector of the present utility model links to each other Yu plastic body, and Zhi is that Zai links to each other The groove (7) of position You certain depth, it can guarantee being connected of encoding block Yu plastic body Intensity can guarantee that You encoding block is fallen by Bai easily, and Zhe is to plastic mold manufacture Be easy to realize.

What of encoding block the coded number of this kind electric connector depend on, if respectively establish 8 encoding blocks on the plug, socket, its codified number is 2 ⁸Individual, promptly 256, if respectively establish 12 encoding blocks on the plug, socket, then the number of codified is 2 ¹², promptly 2048, this number is enough to satisfy the requirement of common equipment.If inadequately, can increase the quantity of encoding block, to reach the purpose of extended coding number.

Be equipped with numeral number on the coding of electric connector, be convenient to carry out binary coding like this.At first make such agreement: when certain encoding block on the plug is retained, this position be 1, when it is removed, it the institute on the throne be 0; The coding method of socket is opposite with the coding method of plug, and promptly when the encoding block on the socket is retained, its institute is on the throne to be 0, and when it was removed, its institute is on the throne to be 1.

Lift a coding method of being compiled this kind electric connector that is No. 586 below.

Fig. 9 is electrical connector plug, the socket rear view that this Zhong is not encoded.

Figure 10 is electrical connector plug, the socket rear view that this Zhong is removed encoding block.

Figure 11 is the front view of Fig. 9.

Figure 12 is the front view of Figure 10.

Figure 13 is the code pattern of this Zhong electrical connector plug.

Figure 14 is the code pattern of this Zhong electric connector socket.

When electric connector is No. 586 by volume, on the plug Encoding block is retained, Encoding block is removed, and according to above-mentioned agreement, its binary number is 1001001010, and promptly decimal number 586; On the socket Encoding block is retained,

Encoding block is removed, and according to a preconcerted arrangement, its binary number numbering also is 1001001010, and promptly decimal number 586.On the plug After encoding block was removed, the encoding block that their left breach are retained on the socket is filled, and was identical because of numbering, and plugs and sockets can plug together.If on the plug Encoding block is retained, and removes

Encoding block, then the binary number of plug is numbered: 1001001110, both decimal number was 590, at this moment, the numbering of plug, socket is inequality, just forms the relation of interfering because of No. 3 encoding blocks on the plug exist, plug, socket can't plug together, and prevent the effect that misplugs thereby reach.

After this electric connector is encoded, if plug, socket numbering is identical, just form one-to-one relationship, plugs and sockets just can plug together; If numbering is different, plug, socket just can not couplings, thereby avoided forming serious consequence because of mispluging electric connector.
