Abstract

PURPOSE:To prevent a damage of a connector in the inserting and pulling operation without causing a dimensional limitation by cutting an escape groove to a pin contact on a plug side on a part of a housing for holding the socket contact of a receptacle. CONSTITUTION:In a receptacle 10, a plurality of escape grooves 14 are provided on a part of both end sides of a housing having a plurality of socket contacts 13 arranged thereon. The width of the escape groove 14 is broader than the diameter of a pin contact 23, and set to a dimension such that the socket contact 13 received in a holding hole 12 causes no dislocation, and the depth of the escape groove 14 is set to a dimension such that the top end part of the pin contact 23 never make contact with a housing 11 even if a plug 20 is pulled out obliquely to the receptacle 10. Thus, the damage of the pin contact or housing caused by 'twisting' at the time of insertion and pulling can be prevented without causing a dimensional limitation.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a connector used for wiring connections of electrical and electronic equipment, and is particularly applicable to information processing connectors with relatively small external dimensions. related to effective techniques.

[Conventional technology]

For example, in information processing equipment, for interconnection of mounting boards inside the case and connection with external peripheral devices, for example, Japanese Patent Laid-Open No. 63-193471, Japanese Patent Laid-Open No. 63-292588, As disclosed in publications and the like, a connector is generally used in which a pin provided on the plug side is inserted into and removed from a socket provided on the shack side.

By the way, in a connector structured to insert and remove a pin and a socket, if the pin is inserted or removed in the axial direction or at an angle with respect to the socket, the pin will come into strong sliding contact with the housing on the socket side. ``There are concerns that this may cause damage to the resin that makes up the housing or bending of the pins.

Therefore, in the case of the former technique disclosed in JP-A-63-193471, a prying prevention piece is provided protruding from the end face of the housing on the socket side, and the prying prevention piece is inserted into the end face of the housing on the bottle side. 2. Prior to insertion and removal of the pin and socket, the strain prevention piece is fitted into the insertion groove so that the pin is inserted and removed parallel to the socket, thereby preventing the above-mentioned We are trying to prevent this from occurring.

In addition, in the case of the latter technique disclosed in JP-A-63-292588, a guide having a slit parallel to the insertion/extraction direction of the pin is provided on the socket side, and a guide is provided on the outer peripheral surface of the housing on the pin side. In this case, a protrusion is provided that fits in parallel with the slit, so that the insertion and removal operations between the pin and the socket are performed in parallel positions.

Furthermore, in a boat-mounted connector, allowances are made in the dimensions and shape of the housing and the arrangement spacing of the pins so that "prying" does not occur even if the connector is inserted or removed at an angle.

[Invention or problem to be solved]

However, as the packaging density of electronic devices continues to increase, there is a growing demand for connectors to have narrower pin spacing and smaller external dimensions.

Under such circumstances, it is practically difficult to provide extra space in the dimensions of the housing or add a guide mechanism other than pins and sockets, as in the prior art described above, due to dimensional constraints. Problems such as damage to pins and housing due to straining have not been solved.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a connector that can prevent damage during insertion and removal operations without imposing dimensional restrictions.

[Means to solve the problem]

A brief overview of typical inventions disclosed in this application is as follows.

That is, the connector of the present invention has a structure in which a plug having pin contacts is fitted into a receptacle having socket contacts, and at least a portion of the housing holding the socket contacts of the receptacle has a plug side A relief groove is carved for the pin contact.

Moreover, the connector of the present invention is a connector having a structure in which a receptacle having a pin contact is fitted into a plug having a socket contact, and at least a part of the housing of the plug holding the socket contact is provided on the receptacle side. A relief groove is carved for the pin contact.

Further, in the connector according to the present invention, the depth and shape of the relief groove vary depending on the position of the housing of the receptacle or plug.

Further, in the connector according to the present invention, the plurality of socket contacts are arranged in at least one row, and the relief groove is carved so that the depth gradually increases from the center part of the socket contact in the housing toward both sides. This is what I did.

[Effect]

According to the above-mentioned connector of the present invention, even if the plug is inserted or removed with the plug tilted relative to the receptacle, the receptacle facing the pin contact or the escape groove provided on the plug side allows the There is no contact between the receptacle or plug housing and the pin contact, which prevents "prying" from occurring.

For this reason, there is no dimensional restriction caused by providing extra mechanisms such as protrusions or guides on plugs and receptacles, and damage to pin contacts and housings caused by "prying" during insertion and removal can be avoided. can be reliably prevented.

[Embodiment 1] Hereinafter, a connector which is an embodiment of the present invention will be described in detail without reference to the drawings.

FIG. 1 is an external perspective view of the connector of this embodiment, and FIGS. 2 and 3 are a side view and a schematic sectional view, respectively.

The connector of this embodiment includes, for example, a receptacle 10 supported by a wiring board (not shown), and a plug 20 inserted into and removed from the receptacle 10.

The receptacle 10 includes a housing 11 made of, for example, heat-resistant and insulating resin, and a housing 11 made of heat-resistant and insulating resin.
The socket contacts 13 are individually housed in holding holes 12 that are opened in a row at a desired pitch on the end face of the socket. Each socket contact 13 is made of a conductor such as a copper alloy, and each connection terminal 13a protrudes toward the back side of the receptacle O and is connected to an unillustrated lead wire or the like.

On the other hand, the plug 20 has a housing 21 made of resin or the like.
The socket contact 1 on the receptacle 10 side is placed inside the recess 22 provided on the end face of the housing 21.
A plurality of pin contacts 2 arranged to correspond to 3.
3, and each pin contact 23 is connected to a cable 24.

By connecting the two so that the housing 11 of the receptacle 1o fits into the recess 22 of the housing 21 of the plug 20, each of the plurality of pin contacts 23 on the side of the plug 20 connects to the corresponding one on the side of the receptacle 10. Each of the socket contacts 13 is deposited.

In this case, in the receptacle 10, a first
As shown in Figures to Figure 3, a plurality of escape grooves 14 are carved. As shown in FIG. 2, the width of this relief groove 14 is wider than the diameter of the pin contact 23, and is dimensioned so that the socket contact 13 accommodated in the holding hole 12 will not be misaligned. Also, the escape groove 14
As shown in FIG. 4, the depth of the pin contact 23 is set to such a size that the tip of the pin contact 23 does not come into contact with the housing 11 even if the plug 20 is inserted into and removed from the receptacle 10 obliquely.

Therefore, for example, even if the plug 20 is tilted relative to the receptacle 10 when inserting or removing the plug 2o into or out of the receptacle 10, the plurality of pin contacts 23 of the plug 2o can be inserted into the receptacle as shown in FIG. Relief groove 14 provided in housing 11 of 10
This prevents the occurrence of "prying" in which the pin contact 23 is strongly slid into contact with the housing 11.

That is, according to the connector of this embodiment, for example, the socket contact 13 can be provided in the housing 11 of the receptacle 10 where the socket contact 13 is located, without adding an extra member such as a guide that causes dimensional restrictions as in the conventional case. Due to the effect of the relief groove 14, "squeezing" during insertion/extraction operation is prevented.
It is possible to reliably prevent damage to the pin contact 23 and the housing 11 caused by this. Therefore, the connector can be made smaller without worrying about damage caused by "prying".

In addition, in the housing 11 of the receptacle IO, when inserting/extracting the pin contact 23 in an inclined state, relief grooves 14 are selectively carved on both end sides where the inclined range becomes large, thereby reducing the strength of the housing 11 and preventing metallization. There is no concern that the shape of the plurality of holding holes 12 in the housing 11 will change after molding.

[Embodiment 2] FIG. 5 is a schematic cross-sectional view of a receptacle lO of a connector according to another embodiment of the present invention.

In the case of this second embodiment, there are a plurality of relief grooves 14a.

The depth dimension of each of the escape grooves 14b and 14c is changed in stages according to the location where they are arranged in the housing 11.

That is, in accordance with the magnitude of the inclination range of each pin contact 23 in the insertion/extraction operation of the connector in the inclined state, the position is shifted from the relief groove 14a on the inside where the inclination range of the pin contact 23 is relatively small to the outer side where the inclination range becomes larger. The escape groove 14c is designed to gradually become deeper as it approaches the end of the housing 11 from the engraved position.

In this way, the strength of the housing 11 and the shape of the housing 11 after molding can be stabilized by appropriately changing the depth of the escape grooves 14a to +4c according to the size of the inclination range of each pin contact 23. Can be maintained in good condition.

Note that in each of the above embodiments, the pin contact 23
and socket contacts 13, respectively, with plugs 20
Although the case where the pin contact 23 is arranged on the receptacle 10 side and the socket contact 13 is arranged on the plug 20 side has been described, the socket contact 13 may also be arranged on the side of the plug 20 where the socket contact 13 is arranged. It goes without saying that a similar effect can be obtained by carving a relief groove in the groove.

Although the invention made by the present inventor has been specifically explained based on Examples above, the present invention is not limited to the above-mentioned Examples, and it is understood that various changes can be made without departing from the gist of the invention. Needless to say.

For example, in each of the above embodiments, the case where there is one row of socket contacts and one row of pin contacts has been described, but two or more rows may be used.

Further, the structure may be such that a plurality of plugs or receptacles can be inserted into and removed from - receptacles or plugs.
