Description

[Detailed Description of the Invention] The present invention relates to a friction lock connector that enables high-density mounting.

A conventional friction lock connector is shown in FIG. Housing 101 of socket connector 10
A socket contact 102 is attached to the housing, and a protrusion 103 is provided on the peripheral wall of the housing. Further, the pin header 20 has a box shape for receiving the socket housing 101, has a pin 202 planted therein, and has an engagement hole 203 in a part of the peripheral wall that engages with the protrusion 103. When the socket connector 10 and the pin header 20 are fitted together, the protrusion 104 of the socket housing 101 slides against the circumferential wall 204 of the pin header for guidance, and the protrusion 103 slides into the engagement hole 2.
03 to lock. In this type of connector, the pin header is box-shaped with an engaging hole in a part of the peripheral wall, so if the pin header is used continuously in series, the side wall 202 portion overlaps and cannot be closely mounted on the board at the same pitch.

The purpose of this invention is to meet the demand for high-density internal mounting due to the miniaturization of electronic devices.The purpose of this invention is to create a friction device that can be closely mounted to the board at the same pitch even when used in series and has a reliable locking structure. To provide lock connectors.

The friction lock connector according to the present invention has side walls on both sides of the pin header in the longitudinal direction, and protrusions are formed on the side walls at positions facing the pin contacts, so that the protrusions can be used when the pin header and socket connector are mated. It is characterized in that it is locked by fitting into the locking hole of the socket contact of the socket housing.

Embodiments of the present invention will be described below with reference to the drawings.

An embodiment of the present invention shown in FIGS. 2 and 3 consists of a socket connector 1 and a pin header 4. As shown in FIGS. The housing 2 of the socket connector 1 is integrally molded from a plastic material and has a plurality of contact insertion holes 21, and a plurality of locking holes 23 on a peripheral wall 22 that communicate with the contact insertion holes 21. The socket contact 3 is locked in the locking hole 23 by a lance 31 and installed in the insertion hole 21, and the contact portion 32 is brought into contact with the insertion opening 24.

The pin header 4 has a plurality of pin contacts 5 arranged in the longitudinal direction and has side walls 6 on both sides parallel to the pin contact row. The side wall 6 is integrally molded from plastic material together with the bottom surface 7 on which the pin contact is planted, and has a protrusion 61 at a position opposite to the pin contact. The protrusion 61 has an engaging surface 61a that is continuous with a chamfered portion 62 having a tapered surface provided at the upper end of the side wall and that engages with the locking hole 23 of the socket housing.

FIG. 4 shows the fitted state of the socket connector and pin header. The socket housing 2 is inserted using the chamfered portion 62 of the pin header as a guide, the socket contact 3 is fitted into the pin contact 5, and the side wall 6 is bent outward by the amount of projection of the projection 61, so that the projection 61 rides over the bottom portion 22a of the side wall. The pin header is then fitted into the locking hole 23, and the locking of the socket connector and pin header is completed.

To separate the socket connector and pin header, pull the socket housing upward with a certain force to release the protrusion 6.
1 and the locking hole 23 are disengaged, and the pin header can be pulled out.

According to this structure, the pin header has a number of mating protrusions corresponding to the number of pin contacts, and there is no wall in the pitch direction, so highly reliable locking is achieved, and the pin header can be inserted continuously as necessary. Close mounting becomes possible.

Furthermore, by making the pin header have a larger number of cores than the socket housing, it is possible to fit a plurality of socket connectors with arbitrarily selected number of cores into one pin header.

As mentioned above, the friction lock connector of the present invention uses the locking hole 23 of the contact of the socket housing as the locking hole for locking with the pin header, so there is no need for a locking hole for locking, and it can be used for molds, etc. The cost is low, a lock can be obtained reliably, and unlike conventional products, there is no wall in the pitch direction of the pin header, so close mounting in the longitudinal direction is possible, and it is extremely effective for increasing the density of internal mounting of electronic equipment.

Although the present invention has been described above using a specific embodiment, the present invention is not limited thereto, and includes various design changes within the scope of the present invention.
