Description

A female signal terminal, an insulating shell and a female connector TECHNICAL FIELD

[0001] The utility model relates to the field of electric connector, concretely relates to a female signal terminal, an insulating shell and a female connector. BACKGROUND

[0002] With the rapid development of intelligent technology of new energy vehicles, the signal connector used on new energy vehicles also tends to miniaturization. The contact density on the vehicle connector is also getting higher and higher, and the contact specification is getting smaller and smaller. How to optimize the structure of the contact while miniaturizing the product to improve the performance of the product has become one of the main research and development directions of the current signal connector.

[0003] The existing miniaturized jack structure, such as the electric terminal disclosed in the Chinese invention application with the application publication number CN115621810A, can meet the current high-density miniaturized electric connection requirements on new energy vehicles. After the electric terminal is inserted into the mounting hole of the insulating shell, the front end of the electric terminal abuts against the corresponding cavity surface of the mounting hole to realize the positioning of the electric terminal in the mounting hole along the insertion direction. A positioning spring is arranged on the electric terminal or the hole wall of the mounting hole to stop cooperating with the corresponding positioning boss on the other after the electric terminal is inserted into place to realize the positioning of the electric terminal in the mounting hole in the direction opposite to the insertion direction. Since the positioning spring can be retracted inward under the action of external force, whether the positioning spring is located on the electric terminal or the hole wall of the mounting hole, the electric terminal may be deflected towards the positioning spring in the mounting hole under the influence of a certain external force, thereby causing the failure of the whole connector. This undoubtedly increases the technical requirements of product structure design, packaging and transportation, assembly and other links, and improves the processing and production cost of the related connector products in the above links.

DETAILED DESCRIPTION

[0031] The scheme principle of the female connector is as follows:

[0032] A female connector comprises an insulating shell 2 and a female signal terminal 1. The insulating shell 2 and the female signal terminal 1 can be inserted and fitted into an integrated body in the arrangement mode shown in FIG. 1 and FIG. 2. The insulating shell 2 is provided with a terminal mounting cavity 3, and the female signal terminal 1 is fixedly inserted into the terminal mounting cavity 3. The structure of the female signal terminal 1 can be referred to FIG. 3-6, and the front end thereof is provided with an anti-inclination convex part 15. The front end of the terminal mounting cavity 3 matched with the female signal terminal 1 is provided with a positioning cavity 16 for being inserted and fitted with the anti-inclination convex part 15, so as to prevent the female signal terminal 1 from being inclined in the terminal mounting cavity 3.

[0033] Since the front end of the female signal terminal 1 is inserted and fitted with the positioning cavity 16 on the insulating shell 2, the front end of the female signal terminal 1 is constrained in the positioning cavity 16 after being inserted in place, thereby making the entire female signal terminal 1 not easy to produce deflection in the terminal mounting cavity 3. Therefore, the above-mentioned setting can ensure the position degree of the female signal terminal 1 in the terminal mounting cavity 3. Even if affected by external force, the female signal terminal 1 is still not easy to produce deflection towards any direction, effectively avoiding the situation that the connector as a whole is caused to fail due to the deflection of the female signal terminal 1.

[0034] Based on the above scheme principle, the embodiment 1 of the female connector of the utility model is as follows:

[0035] A female connector, as shown in Fig. 5, comprises an insulating housing 2 and female signal terminals 1. The insulating housing 2 and the female signal terminals 1 can be assembled together as a whole in the arrangement shown in Figs. 1 and 2. The insulating housing 2 is provided with terminal mounting cavities 3, and the female signal terminals 1 are fixedly assembled in the terminal mounting cavities 3. The insulating housing 2 can be provided with a plurality of terminal mounting cavities 3, such as 10, 20, 30, so that a corresponding number of female signal terminals 1 can be fixedly assembled in the terminal mounting cavities 3. The structure of the female signal terminal 1 can refer to Figs. 3-6, which is a rectangular cylindrical structure. The rectangular cylindrical structure is relatively simple, easy to form, and has good dimensional consistency. The rectangular cylindrical structure has a plug-in interface 6 at the front end for the insertion of the pins of a male connector, and a connecting portion 7 at the rear end for fixed connection with a cable conductor. The rectangular cylindrical structure includes a first side wall 8, a second side wall 9, a third side wall 10, and a fourth side wall 11. The middle portions of the first side wall 8 and the second side wall 9 are hollowed out to form cantilever arms 12 thereon. The cantilever arms 12 of the first side wall 8 and the second side wall 9 are both arched towards the inside of the rectangular cylindrical structure to form contact portions for electrical connection with the pins of the mating male connector. The arched portion of the cantilever arm 12 of the first side wall 8 is also provided with a first elastic arm 13 facing towards the inside of the rectangular cylindrical structure to further improve the electrical contact capability of the cantilever arm 12 with the pins of the mating male connector. The third side wall 10 is provided with a second elastic arm 14 opposite the first elastic arm 13 to increase the contact points on the female connector for electrical contact with the pins of the mating male connector. The cantilever arms 12 of the first side wall 8 and the second side wall 9 are connected together at the ends to increase the contact area of the cantilever arms 12 with the pins of the mating male connector. Since the cantilever arms 12 are located on adjacent two cylinder walls of the rectangular cylindrical structure and are connected to each other, the cantilever arms 12 restrict each other to prevent any side cantilever arm 12 from deforming too much, thereby ensuring that the cantilever arms 12 can always reliably abut against the pins of the mating connector, effectively preventing the problem of failure or reduced service life of the cantilever arms 12 due to excessive deformation.

[0036] When the female signal terminal 1 is assembled in place in the terminal mounting cavity 3, the front end face of the female signal terminal 1 is stopper-fitted with the cavity wall of the terminal mounting cavity 3 to realize the positioning of the female signal terminal 1 in the terminal mounting cavity 3 along the insertion direction thereof. The inner wall of the terminal mounting cavity 3 is provided with a anti-drop elastic claw 4 protruding towards the front end of the female signal terminal 1, and the female signal terminal 1 is provided with a positioning boss 5 for positioning fitting with the anti-drop elastic claw 4. The anti-drop elastic claw 4 is stopper-fitted with the rear end face of the positioning boss 5 after the female signal terminal 1 is assembled in place to realize the positioning of the female signal terminal 1 in the terminal mounting cavity 3 against the insertion direction thereof. In this embodiment, the positioning boss 5 can be provided on the fourth side wall 11. At this time, the anti-drop elastic claw 4 on the terminal mounting cavity 3 is provided opposite to the fourth side wall 11.

[0037] The front end of the female signal terminal 1 is provided with an anti-tilting protrusion 15, and the front end of the terminal mounting cavity 3 is provided with a positioning cavity 16. The positioning cavity 16 is inserted and fitted with the anti-tilting protrusion 15 to prevent the female signal terminal 1 from tilting in any direction in the terminal mounting cavity 3, especially tilting towards the anti-withdrawal pawl 4, thereby avoiding the risk of failure of the female connector due to the tilting of the female signal terminal 1.

[0038] On the basis of the foregoing structure, the key of the present embodiment is that, in order to facilitate the inserted and fitted cooperation of the anti-tilting protrusion 15 and the positioning cavity 16, the side of the anti-tilting protrusion 15 away from the anti-withdrawal pawl 4 is a flat fitting surface 17, and the side of the terminal mounting cavity 3 away from the anti-withdrawal pawl 4 is a flat guiding surface 18. The anti-withdrawal pawl 4 abuts the female signal terminal 1 against the flat guiding surface 18, so that the flat fitting surface 17 of the female signal terminal 1 can be guided and cooperated with the flat guiding surface 18 to facilitate the inserted and fitted cooperation of the anti-tilting protrusion 15 into the positioning cavity 16.

[0039] Specifically, since the anti-withdrawal pawl 4 overhangs towards the front end of the female signal terminal 1, the female signal terminal 1 can be abutted by the anti-withdrawal pawl 4 against the flat guiding surface 18 of the terminal mounting cavity 3 during the insertion into the terminal mounting cavity 3. At this time, the flat fitting surface 17 of the female signal terminal 1 can be guided and cooperated with the flat guiding surface 18, and the anti-tilting protrusion 15 of the female signal terminal 1 can be precisely inserted into the positioning cavity 16. After the female signal terminal 1 is inserted into place relative to the terminal mounting cavity 3, the anti-tilting protrusion 15 at the front end of the female signal terminal 1 is completely inserted into the positioning cavity 16. Therefore, under the abutting and retaining of the cavity wall of the positioning cavity 16 and the anti-withdrawal pawl 4, the female signal terminal 1 is less likely to tilt in the direction away from and towards the anti-withdrawal pawl 4. In this way, the female signal terminal 1 is stably retained in the terminal mounting cavity 3, effectively avoiding the failure of the female connector due to the tilting of the female signal terminal 1.

[0040] It should be noted that when the anti-withdrawal pawl 4 is arranged on the female signal terminal 1 and the positioning boss 5 is arranged on the insulating shell 2, the specific arrangement and technical effects of the anti-tilting protrusion 15 and the positioning cavity 16 can be referred to the foregoing, which will not be described here.

[0041] The positioning boss 5 is integrally bent and formed with the main body of the female signal terminal 1. In this way, the positioning boss 5 and the main body of the female signal terminal 1 have good structural rigidity, avoiding the possibility of structural deformation and failure of the positioning boss 5. Of course, the positioning boss 5 can also be separately welded on the main body of the female signal terminal 1 by welding means, or directly formed by stamping process.

[0042] When the positioning boss 5 is formed by one-piece bending process between the main body of the female signal terminal 1, the side wall of the female signal terminal 1 facing the anti-drop pawl 4 can be a double-layer side wall formed by lapping. The positioning boss 5 is arranged on the outer layer of the double-layer side wall, and the last bending-formed platform wall of the positioning boss 5 extends a clamping wall 19, and the inner layer of the double-layer side wall and the side wall connected with the inner layer are provided with a clamping groove 20 matched with the clamping wall 19. The clamping wall 19 is clamped in the clamping groove 20, so that the positioning boss 5 has good structural rigidity. Referring to FIGS. 1-4, the aforementioned rectangular cylindrical structure further includes a fifth side wall 21. The first side wall 8, the second side wall 9, the third side wall 10, the fourth side wall 11, and the fifth side wall 21 are all formed by one-piece bending of a plate. The fifth side wall 21 is lapped on the outside of the first side wall 8 to form a double-layer side wall, so that the first side wall 8 can be constrained by the fifth side wall 21 from moving outward. The positioning boss 5 is formed by bending part of the fifth side wall 21, and the last bending part extends a clamping wall 19 towards the first side wall 8. The release groove 22 on the fifth side wall 21 for cutting out the part of the positioning boss 5 is provided at the root with a large circular arc to prevent large stress concentration at this position and thus tear the fifth side wall 21. The first side wall 8 and the second side wall 9 are provided with clamping grooves 20 for clamping the clamping wall 19. After the clamping wall 19 is clamped into the clamping groove 20, the front and rear end faces of the clamping wall 19 are in abutting engagement with the corresponding groove faces of the clamping groove 20. In this way, when the female signal terminal 1 is inserted into the terminal mounting cavity 3, the force acting on the positioning boss 5 is shared by the clamping groove 20. In this way, the possibility of deformation or tearing of the root of the positioning boss 5 connected with the fifth side wall is avoided, and the deformation of the positioning boss 5 itself is also effectively avoided. The first side wall 8 and the fourth side wall 11 can also be provided with a connecting groove 23, and the side edge of the first side wall 8 relative to the fourth side wall 11 is provided with a clamping eave 24 matched with the connecting groove 23; the clamping eave 24 is clamped in the connecting groove 23 to strengthen the strength of the cylindrical structure of the female signal terminal 1. The front end of the positioning boss 5 is preferably provided with an inclined inclined surface to reduce the resistance of the female signal terminal 1 when inserted into the terminal mounting cavity 3, thereby improving the efficiency of the female signal terminal 1 when inserted into the terminal mounting cavity 3.

[0043] On the basis of the foregoing structure, the positioning boss 5 can be offset on the female signal terminal 1 along the width direction of the female signal terminal 1. In this embodiment, the positioning boss 5 is arranged on the side of the fifth side wall 21 deviated from the clamping groove 20. In this way, the positioning boss 5 can be used as a mistake-proof structure to facilitate correct installation. Of course, the positioning boss 5 can also be arranged centrally on the central surface of the fifth side wall 21 for ease of design and processing.

[0044] In addition, the female connector can further include a secondary positioning locking piece 26, and a secondary positioning locking matching boss 25 is arranged at the rear end of the female signal terminal 1. The secondary positioning locking matching boss 25 can be formed on the fifth side wall 21 by stamping, and specifically includes a transition inclined surface at the front end and a blocking surface at the rear end. When the female signal terminal 1 is inserted into the terminal mounting cavity 3 in place, the secondary positioning locking piece 26 is fixed at the rear side of the secondary positioning locking matching boss 25, so that the blocking surface of the secondary positioning locking matching boss 25 is blocked and matched with the secondary positioning locking piece 26, thereby achieving the secondary positioning effect of the female signal terminal 1, and further ensuring that the female signal terminal 1 is reliably mounted in the terminal mounting cavity 3. In addition, if the female signal terminal 1 is not inserted into the terminal mounting cavity 3 in place, the secondary positioning locking piece 26 cannot be completely mounted in place. Therefore, whether the female signal terminal 1 is completely inserted in place can be judged by the mounting state of the secondary positioning locking piece 26, so as to ensure the yield of the female connector in production.
