Embodiment

Below with reference to accompanying drawing the preferred embodiments of the present invention are described.

Referring to Fig. 1, Computer signal cable connector of the present invention comprises metal-back 2, a plurality of contact insert pins 5 and insulator 6.

A plurality of contact insert pins 5 pass insulator 6.The insulator 6 that is inserted with contact insert pin 5 is contained in the metal-back 2.

Most important characteristic of the present invention is that the shape of metal-back 2 and contact insert pin 5 is improved, thereby the contact insert pin that will need ground connection ground connection safely promptly, is inserted in the ground connection contact pin in a plurality of contact insert pins 5 in the connector.

At first see metal-back 2, make the inserted

sheet

3,3 of ground connection contact pin ground connection ', be integrally formed in the front of metal-back 2, as shown in Figure 2.These inserted sheets 3,3 ' be used for that the 4th, the 6th and the 11 contact pin ground connection is had the through hole that inserts each ground connection contact pin respectively above.The ground connection contact pin only gets final product ground connection by inserting in these holes, makes things convenient for ground connection work.Here, inserted sheet 3,3 ' shape be not subjected to the restriction of any concrete shape, and also without limits to its material, as long as identical with the material of metal-back 2.Therefore, the work of the work of metal-back and conventional metals shell does not have difference, and it is no problem to this means aspect the availability of metal-back.

On the other hand, several ground connection contact pins integrate (see figure 3) by being connected to each other.That is, in 15 contact insert pins in inserting connector, need 5 contact pins (the 6th, the 7th, the 8th, the 9th and the tenth contact pin) of second row of electrical grounding to be connected to each other formation single-piece contact insert pin 4.By with a ground connection in 5 ground connection contact pins, other contact pin is with automatic ground connection.

The shape of normal contact insert pin 5 as shown in Figure 9.In other words, in traditional connector, these 15 contact pins 5 must insert connector respectively, need the contact pin of electrical grounding to be welded on the electric wire singly in 15 contact pins.These work are very complicated and inconvenient, and cause higher percent defective.According to the present invention, 10 contact pins form shape shown in Figure 9, and insert first and the third line respectively, but second row needs 5 contact pins of electrical grounding to form the contact insert pin 4 of single-pieces, can insert simultaneously by only inserting a contact pin 4 like this.And all 5 contact pins are by being grounded any one ground connection wherein.Therefore, improved the availability of contact pin greatly.

As mentioned above, in connector of the present invention, ground connection contact pin (the 4th, the 6th and the 11 contact pin) is only by can automatic ground connection in the hole of inserting the inserted sheet that metal-back one side forms, other ground connection contact pin (the 6th, the 7th, the 8th, the 9th and the tenth contact pin) by will be wherein any one ground connection and ground connection automatically because they are interconnected into the single-piece contact insert pin.

Connector of the present invention does not need 5 contact pins of second row are carried out the electric wire welding job.This widened first and the third line between working space, thereby greatly facilitate first and the electric wire welding job of the third line.And, owing to saved the electric wire welding job number of leads is reduced, thereby do not form interference, diffraction and radiation between each contact pin.Eliminated interference by this way.Owing to do not need to be used for the lead-in wire of ground connection, in short-circuit test, out of circuit test and voltage-withstand test, do not produce defective.

Because whole single-piece contact pin as the ground connection passage, therefore makes the noise filtering maximization, and owing to does not have contact resistance to make noise by reaching maximization between the contact pin.In fact, the single-piece contact pin of signal cable, metal-back and braid be common ground simultaneously, this means the maximization of ground connection quantity.Based on this, make the noise filtering effect and the maximization of EMI filtering effect of signal cable.

Owing to do not use FERRITE CORE to realize the EMI filtering effect, therefore do not produce the impedance of using FERRITE CORE, the not free delay during the transmission chrominance signal, thus color accurately is transported on the display plane in RGB chromatic rendition process.That is, obtain high image definition.

At last, simplified the structure of connector greatly, and significantly reduced operation quantity (for example, reducing to 72 operations of the present invention), thereby not only machinability and productivity ratio improve, and percent defective reduces greatly from 130 operations of traditional connector.

Although described the preferred embodiments of the present invention for illustrative purposes, one of ordinary skill in the art should be appreciated that and can make different modifications, increases and substitute under the condition that does not depart from the claims of the present invention scope and spirit.
