Description

FIELD OF THE INVENTION

The present invention relates to an electrical connector having right-angle bent terminals, and particularly to an electrical connector having an insulative protector for covering and protecting the terminals.

DESCRIPTION OF THE PRIOR ART

Electrical connectors with a large number of electrical contacts are often used in electrical computers, particularly large computers which produce a high number of transmission signals. To save the space, headers having electrical terminals bent at an angle of approximately 90° from the end of the header are commonly used in the electrical and electronic industry as, for example, on the end of a circuit board. The electrical terminals are usually unprotected and are subject to damage and may collect dust and debris which could interfere with the electrical operations.

Thus, there is a need for a simple, cost effective means to effectively shield the right angle bend electrical terminals to protect persons using electrical equipment from receiving an electrical shock when touching the exposed electrical terminals and to reduce the accumulation of the dust and debris on the electrical terminals. Hence, an improved electrical connector is required to overcome the disadvantages of the prior art.

SUMMARY OF THE INVENTION

Accordingly, an object of the present invention is to provide an improved electrical connector which has a protector steadily assembled to an insulative housing thereof so as to protect a plurality of terminals of the electrical connector and ensure the signal transmission.

To achieve the above object, an electrical connector in accordance with the present invention comprises an insulative housing, a plurality of terminals received in the housing, and an insulative protector. The insulative housing comprises a mating portion having a rear face, a plurality of terminal receiving passageways defined in the mating portion, a pair of sidewalls extending rearwardly from the mating portion and a pair of platforms respectively formed outside of the sidewalls. The protector comprises a top ledge having a pair of tongues formed on opposite ends thereof, and a base having a pair of opposite side latches at the bottom thereof. Each latch has a hook formed at the free end thereof. The tongues of the top ledge and the latches of the base engage the sidewalls of the insulative housing to assemble the insulative protector to the insulative housing.

Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to the drawings and particularly to FIGS. 1-5 , an electrical connector 1 of the present invention comprises an insulative housing 10 , a plurality of terminals 20 , a protector 30 protecting the terminals 20 , a spacer 40 , and a pair of board locks 50 .

Referring to FIG. 2 , the insulative housing 10 comprises a mating portion 11 having a rear face 12 for mating with a complementary connector (not shown), a plurality of terminal receiving passageways 13 defined in the mating portion 11 , a pair of trapezium-shaped sidewalls 14 extending rearwardly from the mating portion 11 , and a pair of platforms 16 respectively formed outside of the sidewalls 14 . A space 15 is defined between the two sidewalls 14 and the rear face 12 of the mating portion 11 for receiving the protector 30 . Each sidewall 14 defines a slot 141 in the top thereof, a recess 145 in the bottom thereof and an opening 142 in rear of the recess 145 . A protrusion 143 and a groove 144 are disposed in the opening 142 . Each platform 16 defines a slit 161 therethrough for receiving a corresponding board lock 50 . Also referring to FIG. 4 , the insulative housing 10 comprises a pair of opposite posts 18 at the bottom thereof to position the electrical connector 1 on a printed circuit board (not shown). The spacer 40 is elongated and comprises a plurality of through holes 41 and a pair of arms 42 respectively formed at opposite ends thereof. Each arm 42 has a catch 421 .

Referring to FIG. 3 , the protector 30 is substantially an insulative panel, and comprises a base 32 and a top ledge 31 projecting from the base 32 . The top ledge 31 has a pair of tongues 311 respectively projecting from opposite ends thereof and a plurality of stoppers 312 projecting from a front edge thereof. The base 32 has a pair of opposite side latches 321 at the bottom thereof. Each latch 321 has a hook 322 at the free end thereof.

Referring to FIG. 6 , the terminal 20 received in the housing 10 comprises a contact portion 21 , an engaging portion 22 perpendicularly connecting with the contact portion 21 , and a tail 23 connecting with the engaging portion 22 and extending out of the insulative housing 10 .

Referring to FIGS. 1 to 6 , in assembly, the contact portions 21 of the terminals 20 are received in the terminal receiving passageways 13 of the mating portion 11 , and the engaging portions 22 perpendicularly extend downwardly. The catch 421 of each arm 42 of the spacer 40 engages the recess 145 of the sidewall 14 of the insulative housing 10 , so that the spacer 40 is assembled onto the insulative housing 10 and the tails 23 of the terminals 20 are respectively inserted through the through holes 41 of the spacer 40 to extend out of the insulative housing 10 . The tongues 311 of the top ledge 31 of the protector 30 are respectively inserted into the slots 141 of the sidewalls 14 of the insulative housing 10 , and the stoppers 312 of the top ledge 31 of the protector 30 abut against the rear face 12 of the insulative housing 10 . The latches 321 of the protector 30 are respectively received in the openings 142 of the sidewalls 14 , and the hooks 322 of the latches 321 are received in the grooves 144 of the sidewalls 14 and engage the protrusions 143 of the sidewalls 14 . Thus, the protector 30 is assembled onto the insulative housing 10 and protects the engaging portions 22 of the terminals 20 from bending. Since the protector 30 is insulative and not a metal cover and the distance between the protector 30 and the terminals 20 is large enough to avoid engagement between the protector 30 and the terminals 20 , the electrical connector of the present invention has better and reliable signal transmission quality.

Although the present invention has been described with reference to the preferred embodiment thereof, it is apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the present invention which is intended to be defined by the appended claims.
