Abstract

The utility model discloses a European style connector, which comprises a male terminal and a female terminal. The two ends of the male terminal and the female terminal are provided with guiding devices which are mutually matched. The guiding devices are provided with guiding holes at both ends of the male terminal and provided with guiding columns at both ends of the female terminal corresponding to the guiding holes. When the connector conducts cooperation, guiding columns arranged at both ends of the female terminal firstly enter the guiding holes at both ends of the male terminal with contact pins and the guiding columns arranged at both ends of the female terminal enter the guiding holes at both ends of the male terminal before the cooperation of the main bodies of the male and the female terminals. Then the contact pins of the male terminal cause the main bodies of the male and the female terminals to carry out the cooperation under the directed action of the guiding columns. After the contact pins of the male terminal are inserted in contact pin holes, the main body parts of the male and the female terminals start cooperated inserted connection. Thus, the contact pins are effectively prevented from hitting to bend caused by first contact. Simultaneously, the guiding range is enlarged and the guiding accuracy is enhanced because of the guiding function of the guiding columns. The European style connector can also be favorable to the realization of blind inserted connection, which causes the assembly to become simple and easy.

Description

DIN connector

Technical field

The utility model relates to connector, is specifically related to a kind of DIN connector that is applied to the industrial power module.

Background technology

Along with China's process of industrialization is further accelerated, the basic mechanization of industrial production, automation, electrification.The industrial machinery of China is the energy mostly with the electricity at present, and European industrial power is used in a large number, and we also adopt DIN connector in large quantities simultaneously.The DIN connector that the new 15A module of industrial power is used on the market, when assembling, occur contact pin easily and hit curved phenomenon, its reason is this connector no obvious guide frame in assembling process, connector as shown in Figure 1, contact pin 011 on the male terminal 01 contacts with the end face 021 of female terminal 02 earlier probably, and the contact pin 011 in the DIN connector is all very tiny, positioning requirements is high again, very easily cause contact pin 011 to damage, and mounting hardness is bigger, thereby has a strong impact on the normal use of module.

The utility model content

The utility model purpose is the deficiency at the existing product technology, and provide a kind of non-damageable, be convenient to the DIN connector that people install.

For achieving the above object, the utility model provides a kind of DIN connector, comprises male terminal and female terminal, is provided with the guider that cooperatively interacts at the two ends of described male terminal and female terminal.

Described guider is to be provided with lead at the male terminal two ends, is provided with the pilot hole corresponding with lead at the female terminal two ends.

Can also be lead to be set, corresponding pilot hole is set at the male terminal two ends at the two ends of female terminal.

The DIN connector beneficial effect that the utility model provides is: this connector is when cooperating, the lead that is arranged on the female terminal two ends enters the pilot hole at male terminal two ends prior to contact pin, and then the contact pin of male terminal is under the orientation of lead, insert pin holes, their main part just enters to cooperate and pegs graft then, hit curved with regard to avoiding contact pin contact earlier effectively like this, simultaneously because the guide effect of lead, also can realize blind slotting connection, make assembling become simple, practical value is strong; If adopt and lead be set, and the mode of corresponding pilot hole is set at the male terminal two ends, have equally and the identical guide effect of preceding a kind of set-up mode at the two ends of female terminal.

Embodiment

The following stated is a better embodiment of the present utility model, does not therefore limit protection range of the present utility model.

Embodiment one, referring to Fig. 2, shown in Figure 3, and the DIN connector that the utility model provides, comprise male terminal 1 and female terminal 2, male terminal 1 is provided with 96 contact pins 11 of 3 rows, and the socket correspondence of female terminal 2 is provided with 96 pin holes, and 2 liang of side positions of male terminal 1 and female terminal are provided with guider.Guider is a kind of lead 21 and pilot hole 12 that can cooperatively interact and use.Lead 21 generally is located at the two ends of female terminal 2, and lead 21 will be a little more than the end face of female terminal 2, and lead 21 is higher than female terminal 2 end faces height partly and is not less than 1mm; Lead 21 is entered in the pilot hole, to realize avoiding the effect of striker prior to contact pin.Lead 21 can adopt double-screw bolt to fixedly connected with female terminal 2 with nut, pilot hole 12 is located at the two ends of male terminal, can certainly be provided with conversely, can pilot hole 12 be set, be provided with the lead 21 corresponding at the two ends of male terminal 1 with pilot hole 12 at female terminal 2 two ends; Lead 21 is a little more than contact pin 11, and lead 21 is higher than contact pin height partly and is not less than 1mm.These two kinds of set-up modes can obtain identical result of use.

Embodiment two, and referring to Fig. 4, Fig. 5, guider can also be in the inboard, two ends of male terminal 1 arc guide groove 13 to be set, and at the two ends of female terminal 2 lead 22 that matches with arc guide groove 13 are set.The use that matches of arc guide groove 13 and lead 22, this setup also can obtain the result of use identical with embodiment one.Also can be provided with conversely, can lead be set in the inboard at male terminal 1 two ends, the arc guide groove that the lead insertion that supplies male terminal is set at the two ends of female terminal 2 is realized guiding.

Because the lead 21 of guider and the effect of pilot hole 12, male terminal 1 have directivity when plugging with female terminal 2, can avoid contact pin to insert like this and tiltedly damage contact pin 11.Chamfering is carried out in end at lead 21, is convenient to lead 21 and inserts in the pilot hole 12.

When being used, the lead 21 at female terminal 2 two ends is introduced into the pilot hole 12 at male terminal 1 two ends, and then the contact pin 11 of male terminal 1 is under the orientation of lead 21, insert pin holes (lead 21 is longer), their main part just enters cooperation then, is hit curved with regard to avoiding contact pin 11 contact earlier effectively like this, simultaneously because the guide effect of lead 21, can realize blind slotting connection, make assembling become more simple, prolong this DIN connector useful life.
