Description

Technical Field

[0001] The utility model relates to an electric connector, in particular to a female socket electric connector. Background Art

[0002] Currently, many electronic products or computer products are equipped with female electrical connectors for external matching male electrical connectors to connect for data transmission and / or charging. Generally, a tongue is provided inside the female electrical connector for multiple metal terminals to be arranged thereon, which can be inserted into the slot of the corresponding male electrical connector to connect with the metal terminals arranged on the slot wall of the male electrical connector.

[0003] Current electrical connectors have different sizes depending on the transmission standards, so the tongue of the female electrical connector is easily damaged by the metal shell of the male electrical connector that is inserted obliquely, or by the shell of a male electrical connector of a smaller size. Therefore, it is common to embed a metal partition laterally in the tongue to increase the strength of the tongue. However, the metal partition has a certain thickness, which also relatively increases the overall thickness of the tongue, thereby limiting the application of the female electrical connector. Utility Model Content

[0004] In view of the disadvantage that the existing female socket electrical connector using a middle partition but thickened tongue has limited application, the main purpose of the utility model is to provide an improved female socket electrical connector, which increases the strength of the tongue by other structures to avoid thickening the tongue.

[0005] To achieve the above-mentioned purpose, the utility model provides a female socket electrical connector comprising:

[0006] A first housing having a front opening and a rear opening;

[0007] A terminal block is disposed in the first housing and comprises:

[0008] An insulating seat, comprising:

[0009] a base, proximate the rear opening of the first housing; and

[0010] a tongue extending transversely from the front end of the base toward the front opening of the first housing and having an upper surface, a lower surface, two opposite outer sides and a front side; and

[0011] At least one terminal set, each of the at least one terminal set has a plurality of metal terminals, and the metal terminals are disposed on the upper surface or the lower surface of the tongue of the insulating seat; and

[0012] A rigid vertical wall is embedded in the two opposite outer sides and the front side of the tongue piece and is harder than the tongue piece and has:

[0013] Two side portions facing each other and respectively partially embedded in the two opposite outer sides of the tongue piece, and at least one of the two side portions forms a height difference portion corresponding to the upper surface or the lower surface of the tongue piece, and the height difference portion is exposed from the tongue piece; and

[0014] A front standing portion is embedded in the front side of the tongue piece and is located between the two opposite side standing portions.

[0015] From the above description, it can be seen that the female socket electrical connector of the present invention mainly embeds the hard vertical wall on the two outer sides and a front side of the tongue piece, and one of the two side vertical parts corresponds to the upper surface or the lower surface of the tongue piece to form a height difference part, and each of the height difference parts is exposed from the tongue piece to be engaged with a locking part of a matching male electrical connector; in this way, the hard vertical wall of the female socket electrical connector of the present invention can not only strengthen the strength of the terminal seat, but also has the locking function of the electrical connector to prevent the male electrical connector from falling off after being plugged in.

[0043] The present invention aims to improve the terminal seat of a female electrical connector, and the technical contents are described in detail with several embodiments and drawings below.

[0044] First see Figure 1 and Figure 2 As shown, the female socket electrical connector 1 of the present invention comprises a first housing 10 , a terminal seat 20 and a rigid vertical wall 30 .

[0045] The first housing 10 has a front opening 11 and a rear opening 12 . In one embodiment, a second housing 13 may be further sleeved outside the first housing 10 .

[0046] The terminal base 20 includes an insulating base 21 and at least one terminal set. The insulating base 21 has a base 211 and a tongue 212. Figure 4As shown, the base 211 is located near the rear opening 12 of the first housing 10 , and the tongue 212 extends laterally from the base 211 toward the front opening 11 of the first housing 10 and has an upper surface 213 , a lower surface 214 , two opposite outer sides 216 and a front side 215 . The terminal group includes a plurality of metal terminals, which are arranged on the upper surface 213 or the lower surface 214 of the tongue, and the rear end of each metal terminal is exposed after passing through the base 211 backward; in this embodiment, the terminal base 20 includes a first terminal group 22 and a second terminal group 23, the first terminal group 22 includes a plurality of first electrode terminals and at least one first signal terminal 223, and the second terminal group 23 includes a plurality of second electrode terminals and at least one second signal terminal 233; wherein the first electrode terminals and the first signal terminal 223 are arranged on the upper surface 213 of the tongue 212, and the second electrode terminals and the second signal terminal 233 are arranged on the lower surface 214 of the tongue 212.

[0047] In this embodiment, the female electrical connector 1 is a charging electrical connector, so the first electrode terminals are composed of a first positive plate 221 and a first negative plate 222, which are much wider than the first signal terminal 223 to increase the rated charging current value; similarly, the second electrode terminals are composed of a second positive plate 231 and a second negative plate 232, which are also wider than the second signal terminal 233. In addition, to meet the matching male electrical connector, it can be plugged in and out for charging, such as Figure 3 As shown in FIG. 1 , the first positive plate 221 and the first negative plate 222 are arranged alternately with the second positive plate 231 and the second negative plate 232, that is, the lower part of the first positive plate 221 corresponds to the second negative plate 232, and the lower part of the first negative plate 222 corresponds to the second positive plate 231. The first signal terminal 223 and the second signal terminal 233 can be located in the middle of the tongue 212, or can be as shown in FIG. Figure 3 As shown, the positions are staggered up and down to match the signal terminal position of the male electrical connector. The first signal terminal 223 is located between the first positive terminal 221 and the first negative terminal 222, and the second signal terminal 233 is located between the second positive terminal 231 and the second negative terminal 232. In other words, the first signal terminal 223 is disposed between the first positive plate 221 and the first negative plate 222, and the second signal terminal 233 is disposed between the second positive plate 231 and the second negative plate 232.

[0048] The rigid vertical wall 30 matches the tongue 212 of the insulating seat 21 and is harder than the tongue 212. It is embedded or partially embedded in the two opposite outer sides 216 and the front side 215 of the tongue 212. Therefore, the rigid vertical wall 30 includes two opposite side parts 32 and 33 and a front part 31 between the two opposite side parts 32 and 33. In one embodiment, the rigid vertical wall 30 is formed by bending a metal plate. However, in order to make the metal plate easy to be completely combined with the tongue 212 during the plastic molding process, at least two metal plates 300 and 301 are prepared. Figure 1 and Figure 2 As shown, from a top view, one metal plate 300 is in a straight line shape, and the other metal plate 301 is bent into an L shape. One end of the straight line metal plate 300 forms a recess 332, and one end of the L-shaped metal plate 301 forms a buckling portion 311 corresponding to the recess 332 to buckle into the recess 332, or can be further laser-fused and joined. The buckling portion or the welded portion is located at one of the side stand portions 33 of the rigid stand 30. Figure 6 As shown, in one embodiment, the buckle portion or the weld of the rigid vertical wall 30a can be located at the front vertical portion 31 of the rigid vertical wall 30a. Figure 7 As shown, the front portion 31 of the rigid vertical wall 30b may further be formed with an opening 312. The rigid vertical wall 30 formed of a metal plate may further be electrically connected to a positive potential, a negative potential or a signal source.

[0049] In addition, the rear ends of the two opposite side standing parts 32 and 33 of the rigid vertical wall 30 penetrate into the base 211, and can further extend a side wing 34 in different directions to be more firmly combined in the insulating base 21. Figure 1 As shown, each of the side portions 32, 33 forms a height difference portion 321, 331 corresponding to the upper surface 213 or the lower surface 214 of the tongue piece 212 to match Figure 5 The corresponding locking member 51 of the male electrical connector 50 is shown. In one embodiment, a height difference portion 321, 331 may be formed on only one of the two side portions 32, 33 corresponding to the upper surface 213 or the lower surface 214 of the tongue piece 212. In this embodiment, the locking member 51 of the male electrical connector 50 is a tuning fork-type buckle clip, which has two buckling portions 511 opposite to each other at the upper and lower sides. Therefore, each of the side portions 32, 33 forms a height difference portion 321, 331 corresponding to the upper surface 213 and the lower surface 214 of the tongue piece 212, respectively, so that the two buckling portions 511 corresponding to the tuning fork-type buckle clip can be buckled therein. In one embodiment, the height difference portions 321 , 331 of the side standing portions 32 , 33 are exposed from the upper surface 213 and the lower surface 214 of the tongue piece 212 , and the front side 215 covers or partially exposes the front standing portion 31 of the rigid vertical wall 30 .

[0050] Please see again Figure 1 and Figure 2 As shown, in order to further strengthen the male electrical connector so that it is not easy to disengage after being inserted into the female electrical connector 1 of the utility model, at least one of the electrode plates can further form a concave-convex portion 224, and a part of the upper surface 213 or a part of the lower surface 214 of the tongue 212 corresponds to the concave-convex portion 224 to form at least one concave-convex area 217, so that the concave-convex portion 224 is matched and accommodated in the concave-convex area 217. In this embodiment, the upper surface 213 of the tongue 212 forms a concave-convex area 217 corresponding to the middle and front position of the first negative electrode plate 222, and the first negative electrode plate 222 forms a concave-convex portion 224 corresponding to the concave-convex area 217; thus, when the male electrical connector is inserted into the female electrical connector 1, the contact portion of the corresponding electrode plate of the male electrical connector will contact the concave-convex portion 224 of the first negative electrode plate 222; preferably, the contact portion of the corresponding electrode plate of the male electrical connector will contact the lowest position of the concave-convex portion 224 of the first negative electrode plate 222.

[0051] In summary, the female socket electrical connector of the present invention mainly embeds the rigid vertical wall on the two outer sides and one front side of the tongue piece, and one of the two side vertical parts corresponds to the upper surface or lower surface of the tongue piece to form a height difference part, and the height difference part is exposed from the tongue piece to be engaged with a locking part of a matching male electrical connector; in this way, the rigid vertical wall of the female socket electrical connector of the present invention can not only strengthen the strength of the terminal seat, but also have the locking function of the electrical connector to prevent the male electrical connector from falling off after being plugged in. In addition, since the tongue piece of the female socket electrical connector of the present invention does not need to be horizontally embedded in the middle partition, the thickness of the tongue piece can be relatively thin, and the problem of insufficient avoidance space between the positive plate and the negative plate when used as a charging connector can be avoided. At least one electrode plate forms a concave-convex part for the corresponding electrode plate of the male electrical connector to contact and reduce the force of pulling out, which also helps to prevent the male electrical connector from falling off after being plugged in.
