[0031] When two mutually isolated circuits are connected, an electrical connector is often used for connection, wherein when two mutually isolated circuits are connected, a plurality of connecting terminals arranged in the electrical connector are used to connect the two mutually isolated circuits.

[0032] In the application process of the electrical connector, one end of the plurality of connecting terminals in the electrical connector is welded in one of the two circuits, and a plug-in connector is arranged in the other circuit. The plug-in connector is inserted into the electrical connector, so that the plug-in connector is connected to the other end of the plurality of connecting terminals, the two mutually isolated circuits are connected, and signal transmission can be performed. In the process of inserting the plug-in connector into the electrical connector, the problem of the deformation of the metal shell of the electrical connector caused by the low strength of the metal shell, thereby increasing the plug-in port often occurs.

[0033] Based on the problems existing in the prior art, the present application provides an electrical connector. As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 indicate that the electrical connector can include a metal shell 10 having an accommodating chamber 103, a plastic main body 11 and a connecting terminal 12.

[0034] The metal housing 10 has an interface 104 for connecting the connector 14 to be inserted. The interface 104 is connected to the accommodating chamber 103. The metal housing 10 is provided with a housing strength reinforcing part 101 to improve the strength of the metal housing 10. The plastic body 11 is disposed on the metal housing 10 and is partially located in the accommodating chamber 103. The connecting terminal 12 is disposed on the plastic body 11. The connecting terminal 12 includes a first end 121 and a second end 122 connected to a circuit. The second end 122 is located in the accommodating chamber 103 and extends out of the plastic body 11. The second end 122 is connected to the connector 14 inserted into the accommodating chamber 103. The connecting terminal 12 is provided at intervals along a first direction. The first direction is perpendicular to the insertion direction of the connector 14 when it is inserted into the accommodating chamber 103.

[0035] Specifically, the metal casing 10 can be a square casing, which can be made of stainless steel. A square profile, slightly larger than the outer profile of the plastic body 11, is formed inside the metal casing 10; this square profile serves as a receiving chamber 103. A square opening, slightly larger than the outer profile of the plastic body 11, is formed on the metal casing 10; this square opening serves as a connector 104.

[0036] like Figure 5 As shown, a first opening 106 may also be provided on the metal housing 10. The first opening 106 communicates with the receiving chamber 103 and is disposed opposite to the insertion interface 104. The outer contour of the plastic body 11 may be square. When the plastic body 11 is installed, it can be fixedly embedded in the receiving chamber 103 of the metal housing 10 (the specific method of fixing the plastic body 11 to the metal housing 10 is not limited in detail). One end of the plastic body 11 extends out of the insertion interface 104, and the other end of the plastic body 11 extends out of the first opening 106.

[0037] When the connecting terminals 12 are configured, they are spaced apart along a first direction on the plastic body 11. The first end 121 can be connected to a circuit by soldering. Specifically, the circuit connected to the first end 121 is set on a printed circuit board 13 (PCB). The first end 121 of the connecting terminals 12 is soldered to the PCB, so that the first end 121 is connected to a circuit on the PCB. A connector 14 is provided on another circuit. When the connector 14 is inserted into the receiving chamber 103, it is connected to the second end 122 of the connecting terminals 12, so that the other circuit is connected to the circuit on the PCB (the circuit on the PCB connected to the first end 121 of the connecting terminals 12) set on the PCB through the connecting terminals 12. The connector 14 can be a flexible printed circuit board (FPC).

[0038] The plastic body 11 can be a high-temperature-resistant and insulating plastic. The material of the plastic body 11 can be determined by those skilled in the art according to actual conditions, and is not limited herein. The connecting terminal 12 can be embedded in the plastic body 11 when the connecting terminal 12 is arranged. The mounting manner of the connecting terminal 12 on the plastic body 11 can be determined by those skilled in the art according to actual conditions, and is not limited herein.

[0039] In the embodiment, the shell strength reinforcing portion 101 is arranged on the metal shell 10, so that the strength of the metal shell 10 is improved. When the plug-in connector 14 is inserted, the strength of the metal shell 10 is improved, so that the risk of the plug-in port 104 of the electrical connector being enlarged due to the weak strength of the metal shell 10 during the insertion of the plug-in connector 14 is reduced.

[0040] In some embodiments, as shown in Figure 1 , Figure 2 and Figure 3 , the metal shell 10 can include a first wall 105, and the shell strength reinforcing portion 101 is arranged on the first wall 105. The first wall 105 is a wall of the metal shell 10 opposite to the plastic body 11 and subjected to a pushing force of the plug-in connector 14 along a second direction after the plug-in connector 14 is inserted into the accommodation cavity 103. The second direction is a direction from the plastic body 11 to the first wall 105.

[0041] Specifically, when the plug-in connector 14 is inserted into the accommodation cavity 103, the second end 122 is connected to the plug-in connector 14 in an abutting manner. Therefore, during the insertion of the plug-in connector 14 into the accommodation cavity 103, the second end 122 will generate an upward force applied to the plug-in connector 14 due to extrusion. During the insertion of the plug-in connector 14 into the accommodation cavity 103, as the insertion depth changes, after the plug-in connector 14 is connected to the first wall 105 of the metal shell 10, the plug-in connector 14 also generates an upward force (a pushing force in the second direction) applied to the first wall 105. Therefore, the first wall 105 is subjected to the greatest force during the insertion of the plug-in connector 14. Therefore, when the shell strength reinforcing portion 101 is arranged, the shell strength reinforcing portion 101 can be arranged on the first wall 105.

[0042] Further, as shown in Figure 1 , Figure 3 , the shell strength reinforcing portion 101 can include a plurality of reinforcing ribs 1011 arranged at intervals. The plurality of reinforcing ribs 1011 are arranged on the first wall 105. One end of the reinforcing rib 1011 is directed in a direction parallel to the first direction.

[0043] Specifically, when the reinforcing ribs 1011 are provided, the reinforcing ribs 1011 are integrally formed with the metal shell 10, i.e., the reinforcing ribs 1011 are formed on the metal shell 10 in the process of processing the metal shell 10, wherein the distance from one end to the other end of each reinforcing rib 1011 is approximately close to the distance between the second wall 107 and the third wall 108 of the metal shell 10, and the second wall 107 and the third wall 108 are two oppositely arranged walls on the metal shell 10. When the reinforcing ribs 1011 are provided, two parallel reinforcing ribs 1011 can be formed on the first wall 105 of the metal shell 10, wherein one reinforcing rib 1011 can be arranged close to the plug-in interface 104, and the distance from the reinforcing rib 1011 to the plug-in interface 104 can be approximately one fourth of the distance between the plug-in interface 104 and the first opening 106, and the other reinforcing rib 1011 is arranged close to the first opening 106, and the distance from the reinforcing rib 1011 to the first opening 106 can be approximately one fourth of the distance between the plug-in interface 104 and the first opening 106.

[0044] Of course, three, four or other numbers of reinforcing ribs 1011 can also be formed on the first wall 105 of the metal shell 10, and the specific number of reinforcing ribs 1011 can be determined by the person skilled in the art according to the actual situation.

[0045] Further, as shown in Figure 1 、 Figure 3 , the reinforcing ribs 1011 are arranged on the outer surface of the first wall 105.

[0046] Specifically, when the reinforcing ribs 1011 are provided, the reinforcing ribs 1011 are formed in the form of integral molding on the outer surface of the first wall 105 along the second direction, and each protrusion is a reinforcing rib 1011, wherein the outer side of the formed reinforcing rib 1011 is approximately V-shaped, and the inner side of the formed reinforcing rib 1011 is also approximately V-shaped, and the outer surface of the first wall 105 is a surface of the first wall 105 away from the accommodation chamber 103.

[0047] In this example, since the reinforcing ribs 1011 are arranged on the outer surface of the first wall 105, the space of the accommodation chamber 103 is not occupied, and therefore the arrangement of the reinforcing ribs 1011 on the outer surface of the first wall 105 can expand the accommodation space in the accommodation chamber 103.

[0048] In some embodiments, one end of the plastic body 11 close to the plug-in interface 104 extends out of the plug-in interface 104 along the third direction to form a first guide portion 111 for guiding the plug-in of the plug-in connector 14 into the accommodation chamber 103, wherein the third direction is opposite to the insertion direction of the plug-in connector 14 into the accommodation chamber 103.

[0049] Specifically, a guide slope is arranged on the plastic body 11 at an extension end close to one end of the plug-in interface 104, and the guide slope on the plastic body 11 is a first guide part 111. The guide slope on the plastic body 11 is arranged on a surface of the plastic body 11 close to the plug-in head 14 when the plug-in head 14 is plugged into the accommodating cavity 103, and the guide slope on the plastic body 11 gradually expands outward.

[0050] In the embodiment, the first guide part 111 can enable the plug-in head 14 to be quickly, accurately and conveniently plugged into the accommodating cavity 103, and improve the plugging speed.

[0051] In some embodiments, as shown in Figure 1 , Figure 3 A second guide part 102 is arranged on the first wall 105 at an end of the plug-in interface 104 to extend out of the plug-in interface 104 in a third direction, so as to guide the plug-in head 14 when the plug-in head 14 is inserted into the accommodating cavity 103.

[0052] In the embodiment, the first guide part 111 can enable the plug-in head 14 to be quickly, accurately and conveniently plugged into the accommodating cavity 103, and improve the plugging speed.

[0053] Specifically, the second guide part 102 can include a guide tongue 1021 extending out of the plug-in interface 104 in the third direction.

[0054] The guide tongue 1021 can be arranged as a guide slope smoothly transitioning at the position of the plug-in interface 104, and the guide slope on the first wall 105 gradually expands outward.

[0055] Further, as shown in Figure 1 , Figure 3 The second guide part 102 further includes a strength reinforcing section 1022, the guide tongue 1021 and the strength reinforcing section 1022 extend out of the plug-in interface 104 in the third direction in sequence, the strength reinforcing section 1022 is in a circular arc shape, the center angle of the circular arc shape is located on the inner surface side of the first wall 105, and an end of the strength reinforcing section 1022 away from the guide tongue 1021 is bent toward the center angle of the circular arc shape.

[0056] Specifically, the end of the strength reinforcing section 1022 connected with the guide slope also smoothly transitions, and the length of the strength reinforcing section 1022 can be determined by a person skilled in the art according to actual conditions when the strength reinforcing section 1022 is arranged, and the angle of the bending of the end of the strength reinforcing section 1022 away from the guide tongue 1021 can also be determined according to actual conditions (the strength reinforcing section 1022 should not affect the plugging of the plug-in head 14).

[0057] It should be noted that the inner surface of the first wall 105 is a surface of the first wall 105 located in the accommodation chamber 103, and the inner surface of the first wall 105 and the outer surface of the first wall 105 are two opposite surfaces.

[0058] In the embodiment, the arrangement of the strength reinforcing section 1022 improves the strength of the second guide portion 102.

[0059] In some embodiments, as shown in Figure 1 、 Figure 3 The guide tongue 1021 and the first guide portion 111 form a horn structure, and the end with a large opening is away from the plug-in port 104.

[0060] Specifically, the guide slope on the plastic body 11 is opposite to the guide slope on the first wall 105, and the end with a large opening of the horn structure formed by the guide tongue 1021 and the first guide portion 111 is away from the plug-in port 104 (the guide tongue 1021 and the first guide portion 111 form an outwardly expanding horn structure).

[0061] In the embodiment, the design of the outwardly expanding horn structure can expand the insertion space of the plug-in connector 14.
