According to a preferred embodiment of the invention, in a process of producing said ground terminal block, 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.

With such a connector, however, use is limited to a particular circuit. Therefore, it is impossible to use the connector for another circuit different in position of contacts to be grounded, unless a new connector is manufactured to meet the different position of the contacts. As the result, new punching dies for contacts are needed whenever circuits to be connected are changed.

In addition, a further process is needed for
3~ commonly connecting the ground terminal blocks lb and lb' of the first and second series of the contacts 1 and 1' at several locations as by welding, so that there is a great ~ 12688~
difficulty in manufacturing in comparison with the connector having only one series of contacts as shown in Fig. 1. As shown in Fig. 2b, furthermore, extra members are necessary such as connecting pieces 3 and 3' and respective series of contacts 4 and 4' having ground terminal blocks lb and lb'. Accordingly, this connector cannot be manufactured by a method wherein a series of contacts 4 is inserted into contact receiving and fixing apertures 5a formed in an insulating housing 5 and fixed therein and thereafter a connecting piece 3 is removed by cutting along a broken line as in a connector having no ground terminal block as shown in Fig. 3. Therefore, the series of contacts 4 and 4' forming the first and second series of contacts 1 and 1' are unavoidably formed by insulating resin molding.
As a result, it is necessary to position the series of the contacts with high accuracy in order to avoid damage to the contacts in connecting the connector with a mating connector, with resulting increased troublesome in production. Moreover, as the contacts are fixed to the molded resin, damaged contacts cannot be replaced or repaired.
Figs. 4a, 4b and 4c illustrate one preferred embodiment of the invention. According to the invention, a connector portion 6 and a ground terminal block 7 are separately made as shown in Fig. 4a. When contacts to .~`

However3 this is troublesome and differe~t die~ ~or fonming the ground terminal blocks are needed every tl~e when the locations of ~he branched connections are changed. To avoid this, common ground terminal block~ 7 having a great numbe~ of branch~d connec~lons 20 are preferably ~ade as shown ir~ Fig. 4~. According to require~ locations of branched ~onnections, required branched connections are retalned and the other un-nece~sary branched connectlons are removed to obtain a ~roun~ termlnal block requi~ed for a connection.
