Description

Connector patch structure

Affiliated technical field

The utility model relates to a kind of connector patch structure, refers in particular to a kind of connector patch structure of cable being adopted the bending location.

Background technology

Connector patch technology is for asking the simplification operation, now many insulative pricking connection (InsulationDisplacement Connection that adopted, IDC) technology, this kind do not need lead carried out processing such as peeling or crimping, and can realize being connected of lead and conducting terminal quickly and easily, so be widely used in field of connectors.A kind of typical insulative pricking interconnection technique is that lead vertically is pressed into the set slit of conducting terminal, and the edge of slit punctures the insulation sheath of lead and forms with the electric heart yearn of lead and electrically connects.This slit is made up of the relative two edges of a slice metal, and this sheet metal has certain width and has sufficient intensity to bear the contact pressure that puts on aforementioned edge to guarantee it.

No. 090222801 announcement technology of Taiwan patent, if in the micro coaxial cable connector assembly in order to the size of lead of transmission power supply signal usually greater than the conductor size of other purposes, its insulated hull is thicker relatively.Cause lead not to be punctured or to puncture to exist deviation easily, can not form excellent electrical property between the conductive core line of lead and corresponding conducting terminal and be connected, influence signal and transmit.

United States Patent (USP) the 4th, 410, No. 222, the insulative pricking portion that punctures the connecting-type terminal is exposed to outside the insulating body fully, when flat cable is pressed into the slit of conducting terminal, because its insulative pricking portion unbraced structure may cause the distortion of insulative pricking portion, and then cause the signal between cable and conducting terminal not transmit reliably.United States Patent (USP) the 5th, 030, No. 132 and the 6th, disclosed several interconnection techniques that puncture for 524, No. 127 respectively, the insulative pricking portion of conducting terminal is that the inwall of accommodating cavity that forms by passing insulating body respectively supports, but, when the operator was pressed into the slit of conducting terminal with lead, therefore these inwalls can not guarantee the precision of assembling with partly stopping operator's sight line.

In addition; be housed in the slit of conducting terminal when lead after; design an Additional Protection structure in case the principal vertical line cable comes off from conducting terminal; as United States Patent (USP) the 5th; the conducting terminal that is disclosed for 030, No. 123, it comprises that a pair of claw-like structure is separated to prevent lead and conducting terminal; but these structures make conducting terminal complicated and will increase manufacturing cost.

In view of this, the utility model designer is at above-mentioned shortcomings and deficiencies, and process studies for a long period of time, and cooperates the utilization of scientific principle, creates a kind of utility model design that can solve above-mentioned deficiency and defective finally.

Summary of the invention

Main purpose of the present utility model provides a kind of connector patch structure, and the channel design that installs of lead is become bending structure, makes lead more firm with being connected of conducting terminal, and data or power supply signal are transmitted more reliably.

For achieving the above object, the utility model can be realized by following technical scheme: the utility model provides a kind of connector patch structure, and this connector comprises insulating body, be housed in plurality of conductive terminals, the bonnet in the insulating body and be coated on the metal shell of insulating body periphery; From being provided with in conjunction with tongue for the ccontaining perforation channel of terminal, each channel vertical lower is established a location division for conducting terminal trifid structure insulative pricking portion conflict fixing to this insulating body by the rear portion; Be provided with the lip limit in insulating body bottom, can guide the arc groove that lead is drawn in the corresponding setting of the ccontaining channel of terminal it on, the insulating body bottom side also is provided with one and stretches into for bonnet button arm and to detain the channel that holds that is set to card in holding; And conducting terminal is provided with the contact site that is housed in the insulating body respective terminal channel and be relatively arranged on the insulative pricking portion of location conduit with contact site, and insulative pricking portion establishes the slit that a clamping lead electrically connects.And the metal shell non-integral is sheathed, but with localized forms insulating body is coated, and which is provided with to being positioned some back-offs on insulating body surface, reaches the button portion for the engaging of bonnet button arm.

This bonnet is a tabular, is provided with the conduit that mates longitudinal register for lead in order at the face of covering, and each channel sidewalls is dashed forward and established the salient point that a conflict holds lead; And draw upper signal channel, the lower channel that is provided with vertical alignment for lead, two interchannels are provided with one and supply accommodating of conducting terminal trifid structure insulative pricking portion insertion, to form the default locate mode of two kinds of different leads, for lead location and derivation.

By the installing of lead guiding access is positioned bonnet, bonnet is covering with insulating body, fasten by bonnet set button arm and insulating body then, each terminal trifid structure insulative pricking portion punctures each lead, lead is led core and is located in the slit and the conducting terminal electric connection, is the L-shaped structure of wire connecting ends location.

Compared with prior art, the utility model connector patch structure has following benefit: the insulative pricking portion of conducting terminal is positioned the conduit of insulating body, be covered with the button arm simultaneously, when lead is pressed into the slit of conducting terminal by insulative pricking portion, the guiding protection is arranged, reduce insulative pricking portion distortion possibility, it is more firm that lead is connected with conducting terminal; Lead adds the strong fix protective effect in the installation and positioning structure of bonnet, avoids external force to directly act on electrical contact point, can prevent effectively that lead and conducting terminal from becoming flexible, breaking away from because of being subjected to the external force effect, thus the data of making or power supply signal reliable transmission more.
