Detailed Description
In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Example 1
As shown in fig. 6 to 9, the present invention discloses a cable connector, which includes a plastic body 200, an electrical contact body, a cable 400, a pull belt 500, and a connector latch 100. The electrical contacts are PCB boards or conductive terminal sets, in this embodiment conductive terminal set 300. The conductive terminal set 300 is installed in the plastic body 200, one end of the cable 400 is electrically connected with the conductive terminal set 300, and the other end extends out of the plastic body 200.
As shown in fig. 1 to 5, a connector latch 100 of the present disclosure includes: a pressing portion 110, a connecting arm 120, and a fixing portion 130. The connecting arm 120 has a bent structure, and two ends of the connecting arm 120 are respectively connected with the pressing portion 110 and the fixing portion 130 to form a U-shaped structure. Two sets of clamping points 111 are disposed on the pressing portion 110, and in this embodiment, the clamping points 111 are integrally formed on the pressing portion 1 by punching. One end of the clamping point 111 is a guiding end for guiding insertion, and the other end is a positioning surface 112. In order to facilitate guiding, the inclined plane is arranged from the guiding end to the stopping surface. The direction from the guide end of the latch 111 to the stop surface 112 (direction of arrow s in fig. 4 a) is opposite to the opening direction of the U-shape (direction of arrow t in fig. 4 a), which is directed toward the mating surface of the connector.
As shown in fig. 7, the plastic body 200 includes a front case 210 and a rear case 220 assembled with each other. As shown in fig. 10, the front case 210 is provided with a mounting portion 230 for mounting the connector latch 100. The mounting portion 230 includes a bottom surface 231, two side surfaces 232, and a stopper 233 located at a rear portion above the two side surfaces 232. The mounting portion bottom surface 231 is provided on both sides with first grooves 234. The rear part of the bottom surface 231 of the mounting part is also provided with a clamping boss 235, and the rear end of the clamping boss 235 is connected with the bottom surface 231 through a third inclined surface 236. The front end of the side 232 of the mounting portion is inclined inwardly to form a lead-in 237. The lead-in 237 serves as a guided plug.
The end of the pressing portion 110 is bent downward to form a guide arm 113, and the guide arm 113 plays a role of abutting guide. The pressing portion 110 is provided with a drawstring hole 114 to facilitate connection of the drawstring. When the pull strap is connected, the pressing portion 110 is pressed by the pull strap force, and the pressing portion 110 may be directly pressed by hand. The pressing portion 110 and the fixing portion 130 are provided with a clearance groove 140 at a middle portion of the connection portion, and the connection arms 120 are disposed at both sides of the clearance groove 140. The provision of the clearance groove 140 facilitates the installation of the rear housing of the connector, so that there is more design space for installation.
As shown in fig. 5, the pressing portion 110 is disposed parallel to the fixing portion 130 or at an inclined angle, so that the front end of the pressing portion 110 has more pressing stroke space. The front end surface of the pressing portion 110 protrudes from the front end surface of the fixing portion 130. The pressing part is connected with the fixing part through the elastic arm, when the pressing part is not installed in the plastic main body, a larger angle can be arranged between the elastic arm and the fixing part, for example, θ can be set to 10 ° to 15 °, when the pressing part is limited and installed in the limiting block 233, 0 ° < θ < 10 °, and further θ=2° to 3 °. Because the U-shaped opening direction is oriented to the butt joint surface of the connector, unlocking can be realized only by a small inclination angle after installation, and the theta is small after installation, thereby being beneficial to the miniaturization design of the connector.
As shown in fig. 4B, when the distance between the stop surface 112 of the clip 111 and the front end of the pressing portion 110 is B and the distance between the front end of the pressing portion 110 and the rear end of the connecting arm 120 is a, b= (0.2-0.4) a. The stop surface 112 is advanced to accommodate a low height board end connector, facilitating a compact design. In this embodiment, in order to achieve a miniaturized design, and make the pressing portion have better elasticity in a small space through pressing, so as to facilitate unlocking, the distance b=22.3±0.4mm between the stop surface of the design stuck point and the front end of the pressing portion, and the distance h=13±0.4mm between the upper surface of the pressing portion and the lower surface of the fixing portion when the pressing portion is mounted in the plastic main body in a limited manner.
As shown in fig. 2, the fixing portion 130 is provided with a first through hole 131, and a first elastic piece 132 bent downward is disposed in the first through hole 131.
As shown in fig. 3, two sides of the fixing portion 130 are provided with clamping portions 150 extending outward from the pressing portion 110. A boss 151 is provided outwardly in the middle of the clamping part 150, and the boss 151 is connected to the front end of the clamping part 150 through a first inclined surface 152. The first elastic piece 132 and the clamping portion 150 are disposed to be positioned and fixed on the plastic body of the cable connector.
As shown in fig. 11, the mounting portion 230 is provided with side grooves 240 on both side surfaces 232, and first and second stepped surfaces 241 and 242 are provided on the inner wall of the side groove 240, and the two stepped surfaces are connected by a second inclined surface 243. As shown in fig. 9, the depth h1 of the first step surface 241 is deeper than the depth h2 of the second step surface 242. The fixing portion 130 of the connector latch 100 is located on the bottom surface 231, such that the first elastic piece 132 is located in the first groove 234. The upper surface of the pressing portion 110 is located below the stopper 233. The clamping portions 150 on both sides of the connector latch 100 are inserted from the side grooves 240, so that the boss 151 slides from the first step surface 241 into the second step surface 242, and is clamped to the second step surface 242. As can be seen from the figure, when the boss 151 just enters the side groove 240, the depth h1 of the first step surface 241 is relatively large, a gap is left between the boss 151 and the first step surface 241, and when the boss enters the second inclined surface 243, the first inclined surface 152 gradually contacts with the second inclined surface 243, and the boss 151 is continuously inserted, so that the boss 151 slides onto the second step surface 242, thereby realizing clamping and fixing. At this time, the front end surface of the clearance groove 140 of the connector latch 100 is located at the front end of the latching boss 235.
As shown in fig. 12, the rear case 220 is provided with a rear case drawstring hole 221, and the drawstring 500 has one end connected to the drawstring hole 114 of the connector latch 100 and the other end extending through the rear case drawstring hole 221. The rear case drawstring hole 221 is inclined at an inclination angle gamma of 40 deg. to 50 deg. to the surface of the rear case 220. The rear case drawstring hole 221 is provided with an inclination angle, so that the rear case drawstring hole 221 functions as a fulcrum, and can be used for changing the direction of force. When the direction of the biasing force of the pull belt 500 is deviated, the connector lock 100 can be biased, and the pressing portion 110 can be swung to unlock.
