Abstract

A housing 1 of a resiliently flexible synthetic material has a plurality of chambers 4 each extending between front side 2 and rear side 3. Each chamber 4 provides accommodation for a contact element 5 having a knurled cylindrical section 9 force-fitted into a cylindrical section 11 of the chamber adjacent the rear side 3. The cylindrical section 11 provides a shoulder 13 supporting an abutting cylindrical collar 12 of the contact element, the diameter of which is greater than that of the knurled cylindrical section 9 and is a sliding close fit in the section of the chamber leading to the front side 2. The contact element has only a pin 15 projecting through the rear side of the housing so that the pin can be plugged into a bore in a circuit board (17). <IMAGE>

Description

A PLUG CONNECTOR This invention relates to a plug connector comprising an insulating housing made of resiliently flexible synthetic material and chambers in the housing being arranged to accommodate contact elements, the chambers being accessible via a front side and a rear side of the housing, at least one contact element being arranged in a respective one of the chambers.
A plug connector of this type has been disclosed for example in the German utility patent 74 24 517 in which the contact element is inserted via the front side of the connector housing into the assigned chamber, where "front side" is to be understood as that side of the housing via which a mating-contact element can be plugged into the contact element located in the chamber. The plug-in depth of the contact element within the chamber is limited by a cylindrical collar which is supported by a shoulder in the chamber wall and whose diameter is greater than a cylindrical section of the contact element which is inserted into a hollow-cylindrical section of the chamber adjacent the rear side of the connector housing.To inhibit movement in the opposite direction, thus the direction opposite to the plug-in direction of a mating-contact element, the contact element is retained in the chamber by a terminal wire which is inserted into, and projects from, an annular groove in a contact element section projecting from the rear side of the housing so that withdrawal of the contact element 15 prevented by abutment of the wire against the rear side of the housing. In this way the contact element is located in a given position in the chamber.
However, the fixing of the contact element in the chamber necessitates the use of relatively rigid terminal wires and does not readily facilitate the direct soldering of a contact element section, which is located on the rear side of the connector housing and which projects from the housing, in the bore of a circuit board.
Therefore it is an aim of the present invention to provide a plug connector such as to simplify the fixing of the contact element in the connector housing.
According to this invention there is provided a plug connector comprising an insulating housing made of resiliently flexible synthetic material and chambers in the housing being arranged to accommodate contact elements, the chambers being accessible via a front side and a rear side of the housing, at least one contact element being arranged in a respective one of the chambers and which has a knurled cylindrical section force-fitted into a hollow-cylindrical section of the chamber adjacent the rear side and providing a shoulder at the transition to a larger diameter portion of the chamber leading to the front side, said shoulder supporting a cylindrical collar which has a larger diameter than the cylindrical section and is accommodated by means of a sliding close fit in the larger diameter portion of the chamber.
An advantageous development consists in that the contact element has only a pin projecting via the rear side of the housing so that the pin can be plugged in to a bore of a circuit board.
Thus the rear side of the housing can form a substantially gap-free contact with a circuit board into the bores of which are plugged the pins of the contact elements projecting from the connector housing.
An embodiment of the invention will now be described by way of example, with reference to the accompanying drawing in which the sole figure is a part-sectional side view of a plug connector embodying this invention.
Referring to the drawing, it can be seen that an insulating strip-housing 1 made of a resiliently flexible synthetic material is traversed between a front side 2 and a rear side 3 by a plurality of chambers 4, each of which is intended to accommodate a contact element 5.
The contact element 5, which can be inserted into a chamber 4 from the front side 2, comprises a section 6 which is provided with contact tongues 8 directed in parallel to longitudinal axis 7 of the chamber 4. When these contact tongues 8 are elastically forced apart, a mating-contact element, e.g. a cylindrical contact pin, can be inserted between these tongues.
In the vicinity of the rear side 3 of the housing 1 the contact element 5 is provided with a cylindrical section 9, whose outer cylindrical surface is provided with knurling, preferably extending longitudinally, i.e. parallel to the chamber axis 7. The diameter of the cylindrical section 9 is contrived to be such that it can be inserted only by a force fit into a hollow-cylindrical section 11 of the chamber 4 which is to accommodate the cylindrical section 9.
In the direction of the front side 2 the cylindrical section 9 is adjoined by a cylindrical collar 12 which has a larger diameter than the cylindrical section 9. Leading to the front side 2, from the hollow-cylindrical section 11, the chamber 4 has a diameter which matches that of the collar 12 so that when the contact element 5 is inserted into the chamber 4 the collar 12 can pass, in parallel with the chamber axis 7, into the chamber 4 in a sliding close fit.
Finally the collar 12 is supported by a shoulder 13 in the chamber formed by the sudden decrease in diameter from the region 14 to the hollow-cylindrical section 11.
When the knurled, cylindrical section 9 has been impressed into the hollow-cylindrical section 11, the contact element 5 is accommodated in the chamber 4 and is adequately protected from being pulled out in either direction via the front side 2 or via the rear side 3.
The contact element 5 projects from the rear side 3 of the connector housing 1 only in respect of a pin 15 which can be plugged into a bore 16 of a circuit board 17.
As the rear side 3 of the connector housing has no elements projecting from the connector housing, for locking the contact element 5 in the chamber 4, the connector housing 1 can contact the circuit board 17 with no gaps between the rear side 3 and the circuit board 17.
Hovement of the contact element in the direction of withdrawal from the chamber is thus inhibited by the force-fit within the hollow-cylindrical chamber section, the knurling of the cylindrical section of the contact element increasing frictional resistance to movement between the contact element and the connector housing. Thus, no additional measures are required on the rear side of the housing to hold the contact element in the housing.
When the contact element is inserted into the housing, the cylindrical collar serves to locate the contact element in the chamber.
