1. Field of the Invention
The present invention relates to a machine for processing electrical connectors, and more particularly, to a machine for cutting pins of the electrical connectors.
2. The Related Art
We know existing connectors for cables are mostly constructed from insulating housings and multiple conductive connector pins. The connector pins are used for transmitting electric power or signals. The insulating housing holds these conductive pins therein for insulating these pins from outside and simultaneously to avoid these pins being into contact with each other. Each pin has a soldering portion for being soldered with one according electric wire of the cable. For conforming with technical standards governing dimensional configuration and electrical characteristics, the housings of the existing connectors often have been available in various designate size and shapes, and a lot of connector pins are commonly disposed in one housing. However, some of these connector pins are functional pins which need to be soldered with the wires of the cable so as to transmit electric power or signals, others of these connector pins are idle pins which have no actual use and need not to be soldered with the wires of the cable. Therefore, for decreasing the possibility of unexpected contacts generated between the adjacent soldering portions or generated between the soldering portions of the idle pins and the electric wires of the cable, it is suggested to cut the soldering portions of these idle pins.
However, in prior art, the soldering portions of these idle pins are often cut by pliers by manual manipulation, the cutting force acted on the pins and the cutting dimensions of the pins are more difficult to control, thereby there may be a high unqualified rate of the products in this producing manner. Furthermore, more manual labor is needed in producing, which increase the producing cost so that cannot be applied in mass production of the connectors.
Accordingly, an object of present invention is to provide a connector pins cutting machine which can provide a high qualified rate in production of the connectors.
Another object of present invention is to provide a connector pins cutting machine which is applied in mass production of the connectors.
To achieve the above objects, a connector pins cutting machine is provided, which is used for cutting soldering portions of idle pins of a connector. The connector pins cutting machine includes a base member, a containing member mounted on the base member having at least one sliding groove extending there-through, a connector-positioning member coupled to the containing member, the connector-positioning member having at least one connector-positioning recess opening upward and communicating with the sliding groove for positioning the connector with the soldering portions of the idle pins extending into the sliding groove, a propeller slidably contained in the sliding groove, a cutting member installed on a front end of the propeller, and a driving member fixed to a rear end of the propeller for driving the propeller together with the cutting member to reciprocate in the sliding groove. Thereby, the soldering portions in the sliding groove are cut by the cutting member.
Constructed as mentioned-above, the connector pins cutting machine can provides predetermined and constant cutting force and cutting dimensions to the pins, thereby decreasing the unqualified rate of the connectors. Furthermore, the connector pins cutting machine is driven by special driving member, so less manual labor is needed, thereby the connector pins cutting machine is adapted to be applied in mass production of connectors.
These and other features, objects and advantages of the present invention will be more fully apparent from the following detailed description set forth below when taken in conjunction with the accompanying drawings.

In present invention, according to one manually manipulating to the switch 14, the connector pins cutting machine 1 will perform one processing procedure. One processing procedure will be described in detail as following: firstly, the relay device 11 activates the rear air-entry pipe 243 to feed the high pressure air into the air cylinder 245 and the exhaust pipe 244 simultaneously to exhaust the existing air in the air cylinder 245, thereby driving the driving shaft 241 to move forward; next the relay device 11 activates the front air-entry pipe 242 to feed the high pressure air into the air cylinder 245 and the exhaust pipe 244 simultaneously to exhaust the existing air in the air cylinder 245, thereby driving the driving shaft 241 to move rearward. It can be seen that, one processing procedure of the connector pins cutting machine 1 corresponds to one reciprocating motion of the driving shaft 241. Furthermore, corresponding to the reciprocating motion of the driving shaft 241, the propeller 25 together with the cutting members 27 installed thereon simultaneously reciprocates in the sliding grooves 222. When the cutting members 27 move forward to a predetermined position, the soldering portions of the idle pins are cut off by the cutting portions 271 of the cutting members 27, and the soldering portions of the functional connector pins remain in the slots 272 of the cutting members 27.

As described above, one advantage of the present invention is that, the two connector-positioning recesses 232 defined in the connector positioning member 23 can reliably position the connector 2 therein. Additionally, the propeller 25 with the cutting members 27 installed thereon is contained in the sliding grooves 222. Therefore, after the connector pins cutting machine 1 being completely assembled, the scope of operation of the cutting members 27 is restrained. That is the cutting force acted on the pins and the cutting dimensions of the pins are predetermined and constant, thereby raising the qualified rate of the connectors.
Another advantage of the present invention is that, the connector pins cutting machine 1 is driven by air pressure driving member 24, thereby less manual labor is needed, and furthermore, more connector-positioning recesses, more cutting members, more sliding grooves and more pillars can be provided in one of this type connector pins cutting machine so as to simultaneously process more connectors. That is, this type of connector pins cutting machine of present invention is consequently applied in mass productions of the connectors.
Although a preferred embodiment of the present invention has been described in detail hereinabove, it should be clearly understood that many variations and/or modifications of the basic inventive concepts herein taught which may appear to those skilled in the present art will fall within the spirit and scope of the present invention, as defined in the appended claims.
