Abstract
ABSTRACT
The multi-contact connector comprises a pair of plugs.
Each plug houses a rigid flat base having a plurality of transverse sockets. A contact insert is mounted in each socket. Each contact insert includes a non-conducting, resilient support body. An electric contact is embedded in the body which resiliently supports the electric con-tact, whereby, in use, when the two plugs are moved toward each other for latching engagement, the electric contacts become resiliently engaged under pressure.

Description
``` ~()~OS58 While the connector of this invention is not limited to the seism~c field, it will be described as having particular utility thereto. Multi-contact connectors are adapted for lnterconnecting seismic detector cables known as geophone cables. In seismic work, the connectors typically become exposed to dirt, sand, water, mud, etc. ~ ;
Conventional seismic connectors require that their contacts be precision manufactured and accurately aligned. Such a conventional connector cannot easily be serviced in the field, since seismic crews are not expected to locate a problem associated with a multi-contact connector and make the required repairs thereto.
The multi-contact connector of this invention is adapted for interconnecting a plurality of conductors.
The connector comprises a pair of plugs. Each plug ~ . .
houses a rigid flat base having a front side and a bottom .
side. The base has a plurality of transverse sockets.
A contact insert is mounted in each socket. Each contact insert includes a non-conducting, resilient support body.
An electric contact is embedded in the body. The contact has a rear end and a front end. The body resiliently supports the front end and means are provided for latching the two connector plugs together so that the front ends of the contacts in one base becomes resiliently engaged under axial pressure with the front ends of the contacts in the other base.

of conductors 8. Connector 10 comprises a pair of substan-tiall~ semi-cylindrical plu~ 11, 12. Each plug supports a flat ri~id base 16 which can be made from metal or plastic.
Each base supports two groups 13, 14 of contact inserts 30 (Figs. 3,4~ in a plurality of transverse, rectangular holes or soc~ets 21, 20 (Fi~.9~. The planes of symmetry of sockets 21 and 20 are perpendicular to each other.
Each insert 30 is removably mounted in its socket 20 or 21.
The preferred embodiment of insert 30 consists of a non-conducting support bod~ 30a made of a resilient ma-terial, such as rubber or the làke, which resilientl~
supports a conductox contact 23 that is em~edded therein.
Contacts 23 can assume varàous configurations and are ~ade out of a flat metal such as copper or alu~inium.
Each metal contact 23 is shaped as shown in Fig. 12, and is characterized by a rear end 25 and a front end 24.
The resilient bod~ 30a has a square top 31 (Fig. 14), a smaller rectangular bottom 3Z, and a reduced neck 33 which snugly fits inside its socket 20 or 21. Each bod~ 30a is ~orcibl~ inserted into its socket b~ first pushing in bot-tom 32 which barel~ s~ueezes through the socket and abuts against one side of base 16, while its top 3I rests on and is supported b~ the opposite side of the base.
The rear ends 25 o contacts 23 project outwardl~ of the bottoms 3Z and are soldered to the conductors 8 of : ~:

~06~5S8 .
cable 7. The front ends 24 of contacts 23 pro~ect out~
wardl~ of the tops 31. Each front end 24 has a rectangular surface 24a (Fig. 12~ whose width dimension w is consi-derably smaller than its length dimension 1 (Fig. 17), so that the ratio ltw is gxeater than one, and, in the preferred embodiment, is between five and ten.
The rectangular top surfaces 24a of a pair of opposed contacts 23 intersect at an angle A, preferably 90. Each front end 24 can move slightl~ inwardly (Figs. 18~ in a vertical direction in response to an axial force F which is reslsted by a nearly e~ual force F' produced by the re-silient support body 3aa. Thus, when a particular contact 23 has a front end 24 which is not properly aligned with the other front ends 24 of contacts 23, such misalignment ~ill be compensated for by its resilient body 30a in which the paxticular contact is embedded. This compensation will be achleved without disturbing the~front ends 24 of the ad;acent contacts 23.
Cable 7 enterR into it~ plug 11 or 12 through an opening ~2 (Figs. 10, 11) and the c~ble is secured to its plug by a conventional split-sleeve chuck 44 (Fig. 1). Conductors 8 and the rear ends 25 o~ contacts 23 are lodged inside a , cavity 45 (Fig. 5) in the plug. A "takeout" cable (not shown) can be provided through another opening 42', as is txpical with connectors used for geophone cables. Base 16 is secured by screws 53 to polarized screw holes 53', 53'' (F~g. 7) so that the base always rests in the same position in its plug.
10~()558 An outwardl~-extendàng shoulder 54 of one plug is adapted to be received by a m~tlng channel 55 in the op-posite plug ~igs. 3, 4). Each'base 16 is pro~ided with a peripheral O-ring 56 whàch seals off the space between the front ends 24, when the connector 10 is latched.
The latchàng means comprise a rotatably mounted sleeve ,~
60 (Fig. 1~ having an inclined recess 61 housing a radially extending pàn 62. The rotation of sleeves 60 causes plugs 11, 12 to move toward each other for mating engagement.
When the connector 10 becomes latched, there becomes ex- ' erted against the enga~ed contact inserts 23 a continuous latching pressure P (Fig. 1~).
To better break awa~ any film of duæt or other foreign matter, the front ends 24 can be provided with teeth (not shown), instead of having flat surfaces 24a (Fig. 12).
The ¢ont~cts 23'in the'two groups 13 and 14 (Fig. 4) ' lie in mutuall~ perpendicular planes. Upon full mating ,'~
engagement of plugs 11, 12, each'pair of opposed contact in5erts 30 will be en~a~ed as best shown in Fig. 16.
To allow either end of a geophone'cable 7 to become '~
coupled to either end of another geophone cable, one half ' ~ "
of the eIectric conductors 8 in ea`ch cable are connected '~, to the inserts 30 of group 13'mounted in sockets 21, and the other half of the conductors 8 are connected to the , ~nserts 3a of group 14 mounted in sockets 20. In this ~, manner plugs 11 and 12 need not be polarized and are in- , terchangeable.
