Description
~ESCRIPTION
CONNECTOR
Technical Field This invention relates to a connector, and particularly to a connector for connecting a battery unit.
Background Art Among connectors of this kind, the popular type in which the contact of a male type connector or a female type connector or the contacts of connectors of both types are exposed outwardly.
Disclosure of Invention However, when the number of electrodes becomes great and the distance between the contacts becomes short, the danger of being short-circuited between the contacts becomes correspondingly great. Especially, in a connector attached to a battery unit cont~;ning a battery of larc~e capacity therein, a contact leading to the electrode of the battery will suffer from great damage when short-circuiting takes place, and will also be dangerous.
The present invention has as its object to elirninate the above-noted defect peculiar to the connector according to the prior art.
To achieve such object, the present invention provides a connector comprising a header having a plurality of post portions mounted thereon in such a manner as to protrude outwardly, and a socket having mounted thereon a plurality of contacts for contacting with the respective post portions of said header and being electrically connecte(~ thereto, said socket ~urther having a plurality of guide grooves for receiving the respective post portions of the header thereinto and guiding them to the corresponding contacts of said socket, said guide grooves forming slots thin enough to be broken when receiving the post portions thereinto or sufficiently narrower than the width of the post portions, these regions oi the contacts of said so,_ket which contact with ~said post portions being provided so as not to be exposed outwardly of said socket.
In the present invention, the contacts of the socket are mounted in the housing of the socket and when the header and the socket fit to each other, the post portions of the header contact with the contacts while breaking or enlarging the guide grooves of the socket.

sest Mode for Carrying Out the Invention The invention will hereinafter be described with respect to an embodiment thereof shown in the drawings.
Figu~es 1 to 3 show the header lO of a connector according to the present invention. ~rhe header comprises a housing lOA and a plurality of contacts 11 and 12 mounted so that the post portion thereof may protrude outwardly from the housing, and with predetermined intervals provided in the lengthwise direction of the housing (see Figures 1 to 3). The details of the contacts are shown in Figures 5 and 6. As can be seen from these figures, the contacts comprise post portions llA, 12A, leg portions llC, 12C and connecting portions llB, 12B connecting these together.
The cross-sectional shape of the housing lOA with the post portions removed is shown in Figure 4. As shown the cross-section thereof has a short leg portion lOa provided at its bottom but generally presents a substantially rectangular shape.
As can be seen from F:igures 2, 5 and 6, at least one (11) of the post portions of the contacts is shorter than the other post portions (12) and the leg portions llC and 12C of the contacts protrude downwardly from the bottom (leg portion) of the housing. Also, at least one of the post portions has its width made narrower than the width of the other post portions. As regards the position at which the post portions protrude from the housing, that of at least one post portion may be made to differ from that of the other poc;t portions.
Figures 7 to 10 show the socket 20 of the connector according to the present invention. The socket comprises a housing 20A and a plurality of contacts 21 for contacting with the respective post portions of the header and being eLectrically connected thereto. The contacts are mounted with predetermined intervals provided in the lengthwise direction of the housing.
Also the-contacts are mounted in the housing except terminal portions which will be clescribed later so that the regions thereof contacting with the post portions may not be exposed outwardly of the housing.
The socket further has a plurality of guide grooves 2Z for receiving the respective post portions of the header thereinto and guiding them to the corresponding contacts of t:he socket.
These guide grooves form slots 22A which are thin enough to be broken when receiving the post portions therein or sufficiently narrower than the width of the post portions. For example, each of the guide grooves is provided so that, as shown in Figure 10, the cross-sectional portion thereof may present a substantially M-shape or so that, as can be seen from Figures 7 to 9, it may be astride at least two (or three) adjacent surfaces of the housing. In the showing, the opposite side regions of each guide groove with respect to the slot are formed thinly cLS compared with the other portions of' the housing and use a mat;erial rich in flexibility to thereby act as a spring.
Each of the contacts of the socket, as shown in Figures 11 and 12, comprises a pair of contact pieces 21A, a, terminal portion 21C and a connecting portion 21B connect:ing these together. The contact pieces are provided so as to be opposed to each other as shown in order to receive the post portion of the header and sandwich it therebetween.
Figure 13 is a cross-sectional view showing the coupled state of the header and the socket. The post portic~ns of the contacts of the header pass through the guide grooves of the socket and are received cmd sandwiched between the mutually opposed contact pieces of t;he socket and electrically connected thereto.
The socket, although not shown, is attached in advance, for example, to a battery unit, and the terminals of the contacts are connected to the electrodes of the unit. Also, the header, although not shown, is mounted, for example, on a printed substrate through the leg ~)ortions of the contacts.
In the socket of the present invention, the plurality of guide grooves for receiving the respective post portions of the header thereinto and guidin,g them to the correspondin!~ contacts of the socket are provided so as to form slots which are thin enough to be broken when receiving the post portions and so that those regions of the contacts of the socket which contact with the post portions of the header may not be exposed outwardly o~
the socket and therefore, the contact portions of the contacts of the socket are not exposed outwardly of the housing, irrespective of before and after the connection of the socket and the header. Accordingly, even when the socket is attached, for .
example, to a unit including a battery of large capacity for use, short-circuiting will not take place and the safety :in handling will be achieved.
Also, each guide groc,ve is provided so as to be astride at least two adjacent surfaces of the housing of the socket and therefore, it becomes possible for the post portions of the header and the contacts oi. the socket to be connected so as to become linear with one a.nother or to intersect one another.
Accordingly, about the connection of the header and socket, the degree of freedom of the d.irection of connection is great.
At least one of the post portions of the conta.cts of the header is shorter than the other post portions and therefore, when the post portions and the contacts of the sockel~ are to be connected together, a diiference in the time for connection occurs between the longer post portions and the sh.orter post portion. Thereby, for~ example the connection of a ground terminal may be staggered :in time so as to take measures such as improving safety. This also holds true of a case where with regard to a header differi.ng in the width of the post portions thereof, the post portic)ns are connected to the contacts of the socket in a direction intersecting the direction of protrusion thereof, and further holds true also of a case where with regard to a header differing in the position of protrusion of the post portions thereof, the post portions are connected to t]-e contacts of the socket in a direction intersecting the direction of protrusion.
