연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록
▼

The invention provides a multi-way tubular connector block including a body having a primary tubular channel of a first diameter, one or more resiliently deformable plug portions having secondary tubular channels of a secondary diameter there through, and a securing mechanism for securing the plug portions to the body, wherein the body has at least two openings or ports in communication with the primary tubular channel, and wherein the secondary diameters of the secondary channels are sized and dimensioned to permit snug fitting of a shock tube therein so that, in use, a plurality of shock tubes are secured in the plug portions so that at least some open ends of the shock tubes are in communication with the primary tubular channel. The invention extends to a multi-way composite connector block having a plurality of multi-way tubular connector block portions substantially as described above.

1. A multi-way composite connector block including a plurality of multi-way tubular connector blocks, each tubular connector block including a body having a primary tubular channel of a first diameter;one or more resiliency deformable plug portions having secondary tubular channels of a secondary diameter there through; anda securing mechanism for securing the plug portions to the body, wherein the body has at least two openings or ports in communication with the primary tubular channel, the securing mechanism for securing the resiliency deformable plug portion being provided on at least one of the ports, and wherein the secondary diameters of the secondary tubular channels are sized and dimensioned to permit snug fitting of a shock tube therein so that, in use, a plurality of shock tubes are secured in the plug portions so that at least some open ends of the shock tubes are in communication with the primary tubular channel; andwherein one port of each of said tubular connector blocks is secured in communication with a corresponding port of at least one other of said tubular connector blocks, the composite multi-way connector block including one or more initiation ports into which one or more detonators or igniters are secured, so that in use when the igniters or detonators are initiated, a signal is propagated to each of the tubular connector blocks and through said connector block out along a plurality of shock tubes. 2. A multi-way composite connector block as claimed in claim 1, wherein, for at least one of the tubular connector blocks, the primary tubular channel is a chamber having curved end zones. 3. A multi-way composite connector block as claimed in claim 2, wherein the end zones of the at least one tubular connector block are semi-spherical or hemi-spherical. 4. A multi-way composite connector block as claimed in claim 2, wherein, for the at least one tubular connector block, at at least one chamber end zone, there is an orifice or reduced diameter in respect to the primary tubular channel which results in a venturi type effect or pressure chamber effect whereby an initiation signal passing from the secondary channels into the primary tubular channel experiences a pressure increase before the orifice and is introduced into the primary tubular channel creating a higher pressure for signal transfer and propagation thereby to promote propagation of a signal from a signal initiation device or source, into the primary tubular channel and then onwards from within the primary tubular channel to the plurality of shock tubes. 5. A multi-way composite connector block as claimed in claim 4, wherein, for the at least one tubular connector block, at one or more of the ports, an attachment means is provided whereby an igniter, or a delayed igniter, being the source of the initiation signal, is attached and secured in communication with the primary tubular channel so that a signal propagating through said primary tubular channel initiates the shock tube by means of said igniter. 6. A multi-way composite connector block as claimed in claim 5, wherein the attachment means is a screw threaded or bayonet type formation to receive and attach a complementary formation on a body of said igniter. 7. A multi-way composite connector block as claimed in claim 6, wherein the screw threads or bayonet formation is on an outer or inner zone of the port. 8. A multi-way composite connector block as claimed in claim 1, wherein the primary tubular channel for at least one of the tubular connector blocks is a chamber that is a flat cylindrical tubular chamber with end zones perpendicular to side walls thereof. 9. A multi-way composite connector block as claimed in claim 1, wherein, for at least one of the tubular connector blocks, each of the one or more plug portions has at least 2 secondary channels there through. 10. A multi-way composite connector block as claimed in claim 9, in which the channels are equi-spaced from each other. 11. A multi-way composite connector block as claimed in claim 9, wherein at least one of the plug portions has 3 to 5 secondary channels there through. 12. A multi-way composite connector block as claimed in claim 1, wherein, for at least one of the tubular connector blocks, the body is made of a plastics material. 13. A multi-way composite connector block as claimed in claim 1, wherein, for at least one of the tubular connector blocks, the securing mechanism is in the form of an aluminium, or other metal, tube which protrudes and is secured into the body and, in use, when a plug portion is inserted into the securing mechanism, a portion of the metal tube which extends from out of the body is crimped onto the plug portion thereby securing the plug portion in position. 14. A multi-way composite connector block as claimed in claim 13, wherein waterproofing material is applied to the tube prior to crimping. 15. A multi-way composite connector block as claimed in claim 13, in which the crimping action alone and the deformability of the plug portion results in a waterproof seal. 16. A multi-way composite connector block as claimed in claim 1, wherein at least one of the tubular connector blocks includes one or more detonators and igniters. 17. A multi-way composite connector block as claimed in claim 1, the tubular connector blocks of the composite multi-way connector block are in communication with each other through a hub or central chamber shaped and dimensioned to promote propagation of the signal. 18. A multi-way composite connector block as claimed in claim 17, wherein the central chamber is curved or spherical or conical having channels therethrough linking specific tubular connector block portions to each other. 19. A multi-way composite connector block as claimed in claim 1, wherein the composite multi-way connector block is made by connecting independent multi-way tubular channel connector blocks. 20. A multi-way composite connector block as claimed in claim 1, wherein the composite multi-way connector block is made by integrally forming the composite multi-way connector block from multi-way tubular channel connector block like portions.
