Definitions

  • This invention relates to a multi contact connector having a ground terminal block and a method of manufacturing the same.
  • a multi contact connector has been used, whose a series of contacts 1 includes some contacts la previously determined to be grounded in accordance with a circuit to be connected and integrally formed with a ground terminal block 1b for commonly connecting the some contacts la as shown in a perspective view of Fig. 1.
  • positions of contacts to be grounded of first and second series of contacts 1 and 1' are not aligned with each other. Moreover, it is required to arrange distal ends la of the first series of contacts 1 in alignment with distal ends la' of the second series of contacts 1' in order to facilitate the connection of the flat cables as shown in Fig. 2a. It is furthermore required to commonly connect ground terminal blocks lb and lb' of the first and second series-of contacts 1 and 1' as by welding 2. To meet these requirements, two kinds of series of contacts 4 and 4' different in shape of ground terminals must be manufactured as shown in Fig. 2b. Moreover, the shapes of ground terminals must be changed every time when positions of the ground terminals are changed.
  • a multi contact connector comprises a ground terminal block_having branched connections, and a connector portion having a plurality of contacts, said branched connections of said ground terminal block being connected to some_-of said contacts of said connector portion to be grounded.
  • the method of manufacturing a multi contact connector comprises steps of producing a ground terminal block having branched connections to be connected to contacts to be grounded in accordance with requirement of a circuit to be connected, and connecting said branched connections with distal ends of said contacts of a connector portion separately produced.
  • a ground terminal block having branched connections at different locations according to requirement of a circuit to be connected is produced every time when the contacts to be grounded are changed, or a ground terminal block having a great number of branched connections commonly formed for requirement of various circuits is produced and then unnecessary branched connections are.removed to form a ground terminal block having the branched connections only required for requirement of a specific circuit to be connected.
  • FIGs. 1, 2a and 2b and 3 are perspective views for explaining connectors of the prior art
  • Fig.s 4a, 4b and 4c are perspective views illustrating the method according to the invention.
  • Figs. 5a and 5b are side views of an application example of a connector portion of the connector according to the invention.
  • Figs. 4a, 4b and 4c illustrate one preferred embodiment of the invention.
  • a connector portion 6 and a ground terminal block 7 are separately made as shown in Fig. 4a.
  • one ground terminal-block 7 is provided, which comprises branched connections 7a to be connected to the contacts to be grounded and is common to a first and second series of contacts 1 and 1'.
  • the ground terminal block 7 is connected to distal ends of required contacts of the connector portion as by welding as shown in Fig. 4b to form a connector having the required ground terminal block.
  • a new terminal block 7 having branched connections at different locations may be made in accordance with the changed contacts to be grounded.
  • this is troublesome and different dies for forming the ground terminal blocks are needed every time when the locations of the branched connections are changed.
  • common ground terminal blocks 7 having a great number of branched connections are preferably made as shown in Fig. 4c. According to required locations of branched connections, required- branched -connections are retained and the other unnecessary branched connections are removed to obtain a ground terminal block required for a connection. In this manner only one kind of ground terminal blocks 7 may be prepared for various connectors required to have different locations of branched connections.
  • ground terminal blocks 7 different in shape are made according to requirements of respective connectors and connected to the connector portions 6, even if contacts to be grounded are changed. Accordingly, connector portions 6 the same in construction can be commonly used without making connectors including two series of contacts and having ground terminal blocks different in shape to meet respective requirements as in the prior art. Moreover, according to the invention, only one ground terminal block 7 is required common to distal ends la and la' of first and second series of contacts aligned in rectilinear rows. As the result, costs of dies and materials to be used are reduced in comparison with those of the prior art and manufacturing of connectors and management of stocks are facilitated.
  • the assembling method the same as that shown in Fig. 3 for forming the connector portion 6 by inserting and fixing a series of contacts into fixing apertures 5a of an insulating housing 5 can be used. Therefore, it is possible to avoid the difficulty in manufacturing in the prior art such as the accurate positioning of two series of contacts in molding to achieve the alignment with a mating connector. At the same time, according to the invention, replacement and repairing can be easily carried out at will.
  • the second series of contacts are inserted reversely to the first series of contacts into fixing apertures 5a to form a connector portion 6 having the first and second series of contacts having the same shape.
  • a connector can be made as so-called "solder-dip type connector".
  • This type connector is produced by cutting distal ends 1a and la l of contacts of the connector portion 6 along- a broken line in Fig. 5a and then by inserting the cut distal ends into insert apertures 8a formed in current conducting portions of a print circuited board 8 to be soldered.
  • the invention can be applied to usual connectors including wires soldered thereto. In this manner, connector for various applications can be produced by commonly using manufacturing installations, thereby contributing rationalization of work and reduction of kinds of products.
  • the manufacturing method according to the invention provides inexpensive multi contact connectors.
