It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application. Also, the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
Fig. 1 shows a schematic structural view of an electrical connector 1 according to an embodiment of the present application. As shown in fig. 1, the electrical connector 1 includes a connector body 11, and the connector body 11 may be made of an insulating material, specifically, plastic. One end of the connector body 11 is opened to form a plugging groove 12, and a plurality of contact terminals 13 are arranged in the plugging groove 12. The contact terminals 13 are made of a conductive material and arranged as required for abutting against the pins of the mating member to form an electrical connection. Because the contact terminal 13 is relatively slender, when it protrudes into the insertion groove 12 and is inserted into the mating part, it is easy to generate tilt and deflection, which causes insertion interference with the mating part. Therefore, the embodiment shown in fig. 1 also provides a terminal fixture 14 within the plug recess 12 of the electrical connector 1.
Referring to fig. 2 to 4, in an embodiment of the present application, the terminal fixing device 14 includes a fixing plate 141, and a plurality of positioning holes 142 are formed on the fixing plate 141 opposite to the plurality of contact terminals 13 disposed in the insertion groove 12. The positioning holes 142 are arranged in accordance with the contact terminals 13 for the plurality of contact terminals 13 to pass through. A sliding guide 144 extends vertically downward from each of two opposite sides of the fixing plate 141, and a guide groove 111 is formed on each of two corresponding sides of the connector body 11. The two slide insertion guides 144 of the terminal fixture 14 are slidably fitted in the guide grooves 111 formed on the respective sides of the connector body 11, respectively, so that the terminal fixture 14 can slide vertically up and down in the insertion groove 12. Also, a first set of mutually cooperating limiting structures is provided between the sliding plug guide 144 and the guide groove 111 of the connector body 11 to limit the fixing plate 141 to a first position at the contact terminal tops 131 (see fig. 3), and a second set of mutually cooperating limiting structures is also provided to limit the fixing plate 141 to a second position at the bottom of the insertion groove 12 (see fig. 4). As shown in detail, the slide insertion guide 144 has first and second guide protrusions 145 and 146 protruding outward from both sides thereof opposite to the guide groove 111, respectively, and a third guide protrusion 147 protruding outward above the same side as the second guide protrusion 146. The connector body 11 has a first guide-groove projection 112 and a second guide-groove projection 113 projecting inward from the upper portion of the guide groove 111 on the respective sides. When the fixing plate 141 of the terminal fixing device 14 is at the first position shown in fig. 3, the lower portion of the first guide protrusion 145 on the slide insert guide 144 abuts against the upper portion of the first guide groove protrusion 112 on the side corresponding to the guide groove 111 to limit the fixing plate 141 from moving downward, and the upper portion of the second guide protrusion 146 abuts against the lower portion of the second guide groove protrusion 113 on the side corresponding to the guide groove 111 to limit the fixing plate 141 from moving upward, so that the fixing plate 141 is limited at the first position by being snapped up and down. When the fixing plate 141 of the terminal fixing device 14 is at the second position shown in fig. 4, the lower surface of the fixing plate 141 abuts against the bottom 122 of the insertion groove 13 to limit the downward movement of the fixing plate 141, and the upper portion of the third guide protrusion 147 on the slide-in guide 144 abuts against the lower portion of the second guide groove protrusion 113 on the corresponding side of the guide groove 111 to limit the upward movement of the fixing plate 141, so that the fixing plate 141 is limited at the second position by being locked up and down. Further, one side of the fixing plate 141, which is not provided with the sliding insertion guide, is further provided with a sliding insertion structure matched with the inner wall of the opposite insertion groove 12, so as to provide further guiding and positioning functions for the vertical sliding movement of the fixing plate 141. Referring to the embodiment shown in fig. 2 and 3, a plurality of ribs 121 are formed on an inner wall of the inserting groove 12, a plurality of sliding grooves 143 facing the plurality of ribs 121 are formed on a side surface of the fixing plate 141, and the fixing plate 141 slides with the plurality of ribs 121, and when the fixing plate 141 slides up and down in the inserting groove 12, the plurality of ribs 121 and the plurality of sliding grooves 143 are also in sliding contact with each other.
When the electrical connector 1 according to the above-mentioned embodiment of the present application is assembled, the terminal fixing device 14 is first inserted into the insertion groove 12 in a sliding manner and pushed to the bottom of the insertion groove 12, and at this time, the lower surface of the fixing plate 141 abuts against the bottom 122 of the insertion groove 13, the first guide protrusion 145, the second guide protrusion 146 and the third guide protrusion 147 on the sliding guide 144 respectively pass over the first guide groove protrusion 122 and the second guide groove protrusion 123 on both sides of the guide groove 12 under the pushing force, and the upper portion of the third guide protrusion 147 on the sliding guide 144 abuts against the lower portion of the second guide groove protrusion 113 on the corresponding side of the guide groove 111, so as to limit the fixing plate 141 from moving up and down. To facilitate the retention of the guide protrusions of the chute guide 144 over the guide protrusions of the chute 12, the chute guide 144 is preferably centrally formed with a vertically extending slot 148 to enhance the deformability of the chute guide 144. After the terminal fixture 14 is placed at the bottom of the insertion groove 12, the contact terminals 13 are implanted in the connector body 11 and the contact terminals 13 are passed through the positioning holes 142 in the fixture plate 141, as shown in fig. 4. After the contact terminal 13 is fully planted, a certain force is applied to make the fixing plate 141 of the terminal fixing device 14 release the limit restriction of the second position and slide upward. When the fixing plate 141 is slid upward to a first position at the contact-terminal top 131, the lower portion of the first guide projection 145 on the slide-in guide 144 abuts against the upper portion of the first guide-groove projection 112 on the corresponding side of the guide groove 111 and the upper portion of the second guide projection 146 abuts against the lower portion of the second guide-groove projection 113 on the corresponding side of the guide groove 111, thereby restricting the fixing plate 141 from moving up and down to be held in the first position, as shown in fig. 3. At this time, the top 131 of each contact terminal 13 is inserted into the positioning hole 142 of the fixing plate 141, so that the fixing plate 141 provides a good fixing and holding effect for each contact terminal 13, and the contact terminals 13 are prevented from tilting.
When the electrical connector 1 according to the above embodiment of the present application is plugged into the mating part 2, as shown in fig. 5, first, during the process that the plugging convex portion 21 of the mating part 2 gradually enters the plugging groove 12 of the electrical connector 1 to plug with the contact terminal 13, the fixing plate 141 of the terminal fixing device 14 is pushed by the plugging convex portion 21 of the mating part 2 to slide downward, and always provides support for the contact terminal 13, so as to prevent the contact terminal 13 from tilting. When the plugging convex part 21 of the docking piece 2 is plugged in place, as shown in fig. 6, the fixing plate 141 is just pushed by the plugging convex part 21 of the docking piece 2 to abut against the bottom 122 of the plugging groove 12 to be in the second position. With the aid of the terminal fixing device 14, the plugging process of the electrical connector 1 and the mating member 2 is smoothly performed, and problems such as mating interference and the like do not occur.
According to another embodiment of the present application, as shown in fig. 7, the sidewall 123 of the inserting groove 12 may further be formed with a through hole 124, so that a tool can pass through the through hole 124 to lift the fixing plate 141 at the second position and slide to the first position.
According to still another embodiment of the present application, as shown in fig. 8, in case that the inner wall of the insertion groove 12 is further provided with the barb 125, the fixing plate 141 can enter the second position at the bottom of the insertion groove 12 by pulling back the barb 125 by a tool when the terminal fixing device is mounted. After the contact terminal is fully implanted, the fixing plate 141 is moved up to the first position to fix and protect the top of the contact terminal, and the barb 125 is pushed open, so that the insertion convex part 21 of the butt-joint piece 2 can be smoothly inserted.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
