Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a male-male connector, and particularly to its lock structure.

In a typical male and female mating type connector, the pin contact fixing part where the pin contact is held by an insulator, the contact part between the pin contact and the mating contact, and the wiring part of the mating contact are:
Since they are arranged almost in a straight line with each other, the total length from the pin contact fixing part to the connection part of the mating contact is large. Therefore, for example, if an insulator holding a pin contact is installed on a board and the end opposite to the contact part of the pin contact is penetrated through the board, the mounting height on the board becomes large. It ends up.

Therefore, an object of the present invention is to provide a male-female connector that can reduce the overall height.

Another object of the present invention is to provide a lock structure in a connector that achieves the above objects.

Hereinafter, the present invention will be described using examples with reference to the drawings.

FIG. 1 shows an embodiment of a cross-contact type connector according to the present invention. This connector includes two male-female insulators 10 and 20 made of thermoplastic resin such as nylon. Female side insulator 1
Several thin partition walls 12 are formed in the fitting hole 11 at equal intervals. Pin contacts 30 are installed at positions corresponding to the partition walls 12, respectively. The pin contact 30 is made by bending a conductive bar material having a diameter larger than the thickness of the partition wall 12 into an L shape, and one side of the bent portion is passed through the female insulator 10 in the mating/disengaging direction 40. A contact portion 31 extends in a perpendicular direction, and the other side of the bent portion is a connecting portion 32 extending parallel to the fitting/disengaging direction 40. pin contact 3
0 into the female insulator 10, the part having the connecting portion 32 is pushed into the narrow entrance groove 13 formed on the side surface of the female insulator 10. At that time, the entrance dimension of the groove 13 is made slightly narrower than the pin diameter of the pin contact 30, so that when the pin contact 30 is pushed into the groove 13, the groove 13 is elastically deformed, is pushed in with a snap, and the pin contact 30 is pushed in. Make sure that it is firmly fixed in the groove 13. Note that the pin contacts 30 are attached alternately from both sides of the female insulator 10 one by one.

On the other hand, the tip of the male insulator 20 has a notch 21 at a portion corresponding to the partition wall 12 of the female insulator 10. The width dimensions of these notches 21 are such that they can accommodate the pin contacts 30. The male insulator 20 also incorporates socket contacts 50 as mating contacts at positions corresponding to the notches 21. The socket contact 50 is made of a conductive plate material, and the second
It is mechanically and electrically connected to an electric wire 60 as shown in the figure. The tip of the socket contact 50 is bifurcated and extends to the left and right of the notch 21. Contact portions 52, 52 are formed in the bifurcated portions 51, 51, which face each other with an interval narrower than the diameter of the pin contact 30. These contact portions 52, 52 slightly protrude into the notch 21, as is clear from FIG. Note that the socket contact 50 is provided with a locking pawl 54 for locking onto the male insulator 20, but these can be modified in various ways.

Furthermore, in some of the plurality of notches 21,
Like the notch 21a at the end in FIG. 1, a narrow portion 22 is formed in the middle of the fitting/disengaging direction 40. The width of the narrow portion 22 is smaller than the diameter of the pin contact 30. Moreover, a slope 23 is formed on the entrance side of the narrow portion 22. In this way, this cut 2
1a serves as a locking groove.

Now, when the male insulator 20 is fitted to the female insulator 10, the rear end surface 14 of the female insulator 10 and the front end surface 24 of the male insulator 20 are substantially The contact portions 31 of the pin contacts 30 and the contact portions 52 of the socket contacts 50 are in contact with each other, and an electrical connection is obtained. At this time, the overall height H from the surface of the substrate 70 is simply that of the male insulator 20 itself, so
It is possible to reduce the overall height.

Further, when the female insulator 10 and the male insulator 20 are fitted together, the pin contact 30 is inserted into the notch 21. In that case, the pin contact 30 inserted into the notch 21a which is the locking groove
is inserted into the inner part of the notch 21a as shown in FIG. 5 while expanding the narrow portion 22 along the slope 23. In this state, even if an unexpected force that pulls the connector apart acts, the pin contact 30 engages with the narrow portion 22, so that the fitting will not easily come off. Therefore, the mutually fitted state of the connectors is maintained. According to this lock structure, since no special lock device is added, the external size does not increase.

Note that the locking strength can be set to a desired value by appropriately selecting the number of notches 21a, which are locking grooves.
