Description

Technical Field

[0001] This utility model relates to the field of electrical connectors, and in particular to a pluggable male connector. Background Technology

[0002] Plug-in connectors are electronic components used to achieve electrical connections. They are used in various electrical devices to facilitate wiring. Their function is to act as a bridge between interrupted circuits or independent circuits, undertaking the task of current or signal transmission; or they can be used in conjunction with electrical terminals to form board-to-wire connections; they can also be used independently for board-to-board connections. Plug-in terminal blocks are widely used in various fields, such as the automotive and electric vehicle industries, and various electronic equipment fields, to connect various electrical components.

[0003] As part of a connector system, pluggable male connectors connect and disconnect circuits via plugging and unplugging with female connectors. Traditional pluggable male connectors typically use a plastic-coated structure. However, because different connectors have different terminal shapes, the corresponding plastic shell needs to be specially designed and injection molded according to the terminal structure to ensure the positioning and use of the terminals. Therefore, the separate design and manufacturing of the plastic shell increases costs and reduces production efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a pluggable male connector so that the plastic structure can be used for at least two types of terminals.

[0005] To solve the above-mentioned technical problems, the present invention provides a pluggable male connector comprising a plastic body and a terminal assembly. The plastic body has a first surface and a second surface that are relatively distributed along a plugging direction. A plugging cavity is formed on the plastic body along the plugging direction, penetrating the first surface and the second surface. The plugging cavity allows at least two sets of terminals to be selectively inserted into it, thereby enabling the use of multiple terminals. This eliminates the need to design a special plastic body for different terminals, thus saving costs to a certain extent.

[0006] Furthermore, of the at least two sets of terminals, one set of terminals is configured as a straight terminal and the other set of terminals is configured as a bent terminal; one end of the insertion cavity is provided with a limiting groove for limiting the bent terminal, so that it can be used for both types of terminals.

[0007] Furthermore, the bent terminal has a straight section extending along the insertion direction and a bent section perpendicularly connected to one end of the straight section; the straight section is inserted into the insertion cavity, and the bent section passes through and is confined in the limiting groove to increase the stability of the bent section.

[0008] Furthermore, the limiting groove is disposed on one side cavity wall of the insertion cavity along the bending section, the limiting groove penetrates the one side cavity wall along the bending direction, and the limiting groove is recessed along the insertion direction so that the bending section can pass through it.

[0009] Furthermore, the insertion cavities are configured as a plurality of rectangular arrays, forming at least one column of insertion cavities and several rows of insertion cavities. When the bent terminals are inserted into the plurality of insertion cavities one by one, the bent sections are distributed in the column direction. In the plurality of rows of insertion cavities, the recess depth of the limiting groove of each row of insertion cavities gradually increases along the extension direction of the bent section, so that the bent sections of each column can pass through the limiting groove accordingly.

[0010] Furthermore, the insertion cavity is configured in multiple rows, and a groove for reducing adhesive is formed between the cavity walls of two adjacent rows of insertion cavities to facilitate adhesive reduction.

[0011] Furthermore, the insertion cavity includes an assembly cavity, a limiting cavity, and a mating cavity arranged sequentially along the insertion direction. The limiting groove is disposed on one end of the assembly cavity away from the mating cavity. When a linear terminal is inserted into the insertion cavity, the linear terminal is confined in the limiting cavity. The two ends of the linear terminal pass through the assembly cavity and the mating cavity, respectively, to facilitate the mating between each set of terminals and the plastic body, as well as the mating between the plastic body and the complementary connector.

[0012] Furthermore, the insertion cavity includes an assembly cavity, a limiting cavity, and a mating cavity arranged sequentially along the insertion direction; when the bent terminal is inserted into the insertion cavity, the straight section of the bent terminal is limited in the limiting cavity, and the end of the straight section away from the bent section extends into the mating cavity, while the end closer to the bent section extends into the assembly cavity; the bent section of the bent terminal is blocked outside the assembly cavity and is limited in the limiting groove to facilitate soldering to the circuit board.

[0013] Furthermore, the outer surface of the plastic body is provided with a snap-fit ​​structure to facilitate mating and engagement with the corresponding complementary connector.

[0014] Furthermore, connecting components are provided on opposite sides of the plastic body, and the connecting components are used to connect with the mating connector.

[0015] The pluggable male connector of this utility model has at least the following beneficial effects: by setting a plugging cavity on the plastic body, the plugging cavity can allow at least two sets of terminals to be inserted into it, thereby allowing at least two types of terminals to be inserted into it. There is no need to design a special plastic body for at least two types of terminals, which saves costs to a certain extent and simplifies the production and manufacturing difficulty.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figures 1 to 5 As shown, the pluggable male connector of this utility model includes a plastic body 1 and a terminal assembly. The plastic body 1 is used to protect the terminal assembly and also serves as insulation. The terminal assembly is used to electrically connect and cooperate with complementary terminals and circuit boards to realize the transmission of electrical signals.

[0026] In this embodiment, the plastic body 1 is injection molded from plastic and has insulating and protective functions. The plastic body 1 has a square structure and has a first surface 111 and a second surface 112 that are distributed opposite to each other along an insertion direction. The insertion direction is the height direction of the plastic body 1, and the first surface 111 and the second surface 112 are horizontal planes that are parallel to each other. An insertion cavity 12 is formed on the plastic body 1 along the insertion direction, penetrating the first surface 111 and the second surface 112, and the terminal assembly can be inserted into it along the insertion direction. The insertion cavity 12 includes an assembly cavity 121, a limiting cavity 122, and a mating cavity 123 that are distributed sequentially along the insertion direction. The assembly cavity 121 is located on the side closer to the first surface 111, and the mating cavity 123 is located on the side closer to the second surface 112. The assembly cavity 121, the limiting cavity 122, and the mating cavity 123 are all cuboid structures. The size of the limiting cavity 122 is adapted to the structure of the terminal assembly so that the terminal assembly can be inserted into it along the insertion direction. The outer wall of the portion of the terminal assembly that passes through the limiting cavity 122 is fitted to the inner wall of the limiting cavity 122 to restrict the movement of the terminal assembly in a direction perpendicular to the insertion direction. In this embodiment, the size of both the assembly cavity 121 and the mating cavity 123 is larger than the size of the limiting cavity 122. The larger size of the assembly cavity 121 is to reduce the amount of plastic used, thus saving plastic costs. The larger size of the mating cavity 123 is to adapt to the protruding structure corresponding to the mating connector, allowing the protruding structure corresponding to the mating connector to pass through it, thereby improving the stability between the plastic body 1 and the mating connector.

[0027] In this embodiment, a limiting groove 13 is provided on one side of the cavity wall of the assembly cavity 121 of the insertion cavity 12. The limiting groove 13 is recessed from one end of the assembly cavity 121 near the first surface 111 (i.e., from one side of the assembly cavity 121 near the first surface 111 or the end away from the docking cavity 123) along the insertion direction. In this embodiment, the insertion cavities 12 are configured in a rectangular array, forming at least one column and several rows. The column direction towards one side is defined as positive. Each insertion cavity 12 has a limiting groove 13 on both sides of its assembly cavity 121 along the column direction. Alternatively, each insertion cavity 12 can have a limiting groove 13 on one side of its assembly cavity 121 from the center along the positive column direction. Each limiting groove 13 penetrates the first surface 111 and extends through the cavity wall along the column direction, allowing the corresponding structure of the terminal assembly to be inserted into the limiting groove 13 along the insertion direction. In the rows of insertion cavities 12, the depth of the limiting groove 13 in each row gradually increases along the positive column direction, allowing the terminal assemblies in each column to be distributed sequentially along the depth of the limiting groove 13 without interfering with each other. Preferably, the insertion cavities 12 are arranged in several columns, and a glue-reducing groove 18 is formed between the cavity walls of the assembly cavity 121 of any two adjacent columns of insertion cavities 12 to reduce glue and save costs.

[0028] In this embodiment, both ends of the limiting cavity 122 are wide-mouthed to facilitate the quick insertion of the terminal assembly. In this embodiment, the mating cavity 123 extends through the second surface 112, and a protruding post 14 is provided on the side of the mating cavity 123 near the assembly cavity 121. The limiting cavity 122 extends through the protruding post 14 to increase the contact area of ​​the terminal assembly with the inner wall of the limiting cavity 122, thereby improving stability. A cross-shaped reinforcing rib 15 is formed on the outer wall of the protruding post 14. The mating cavity 123 includes an insertion cavity section 1231 that mates with the mating connector and a truncated trapezoidal clearance cavity section 1232 that connects to the insertion cavity section 1231. The narrow side of the clearance cavity section 1232 faces the insertion cavity section 1231 and connects to the insertion cavity section 1231. After the corresponding structure of the mating connector is inserted into the insertion cavity section 1231, the clearance cavity section 1232 is used for clearance.

[0029] In this embodiment, connecting components 16 are provided on opposite sides of the plastic body 1 (i.e., on both sides along the direction of the plastic body 1). The connecting components 16 include connecting blocks 161 in a specific direction, mounting holes 162 recessed in the connecting blocks 161 along the insertion direction, and nuts 163 screwed into the mounting holes 162. In this embodiment, the plastic body 1 can mate with a mating connector with screws, so that the screws of the mating connector are aligned with and screwed into the nuts 163 to achieve connection and fixation between the plastic body 1 and the mating connector. T-shaped positioning protrusions 164 are provided on the opposite side of the two connecting blocks 161 to facilitate riveting with corresponding T-grooves on the inner wall of the mating connector. In another embodiment, connecting components 16 are provided on opposite sides of the plastic body 1, and buckle structures are symmetrically provided on opposite sides of the plastic body 1. The buckle structure includes a triangular buckle block 17. The buckle block 17 can be snapped into the buckle slot after the plastic body 1 is inserted into the slot by opening a slot on the inner wall of the groove structure corresponding to the docking connector.

[0030] like Figures 1 to 4 As shown, in this embodiment, the terminal assembly includes at least two sets of terminals, and only one set of terminals is selected and inserted into each plastic body 1, while a selected terminal is inserted into each insertion cavity 12.

[0031] In at least two sets of terminals, one set of terminals is configured as a straight terminal 21 and the other set of terminals is configured as a bent terminal 22. Each terminal can be inserted into a limiting cavity 122, and a limiting groove 13 is used to limit the bent terminal 22 so that the bent terminal 22 can pass through the limiting groove 13. The straight terminal 21 passes through the insertion cavity 12 along the insertion direction.

[0032] In this embodiment, the linear terminals 21 are distributed in a straight line only along the insertion direction. When the linear terminals 21 are selected to be installed on the plastic body 1, a linear terminal 21 is inserted into each insertion cavity 12. The middle part of the linear terminal 21 passes into the limiting cavity 122 and is located therein. One end of the linear terminal 21 passes into the mating cavity 123 for mating with the mating terminal of the mating connector to realize the transmission of electrical signals. The other end of the linear terminal 21 passes through the assembly cavity 121 and protrudes from the first surface 111 of the plastic body 1. The end of the linear terminal 21 protruding from the first surface 111 is used for soldering to the circuit board.

[0033] In this embodiment, the bent terminal 22 has a straight section 221 extending along the insertion direction and a bent section 222 perpendicularly connected to one end of the straight section 221. The bent section 222 extends in a direction perpendicular to the straight section 221 after being bent from the straight section 221. When the bent terminal 22 is selected to be installed on the plastic body 1, one bent terminal 22 is inserted into each insertion cavity 12. The middle part of the straight section 221 is inserted into the limiting cavity 122, and the end of the straight section 221 away from the bent section 222 passes into the mating cavity 123 for mating with the mating connector. The end of the straight section 221 near the bent section 222 extends into the assembly cavity 121. The bending sections 222 extend from the straight sections 221 in the forward direction of the column. Therefore, a limiting groove 13 is provided on one side wall of the insertion cavity 12 along the extension direction of the bending sections 222, and the limiting groove 13 penetrates this side wall along the bending direction of the bending sections 222. Each column of bending sections 222 enters the limiting groove 13 in the forward direction of the column, and the length of each bending section 222 in each column gradually decreases. Furthermore, a portion of the straight sections 221 in each column penetrates into the assembly cavity. The lengths of the grooves gradually decrease along the column direction, while the depth of each column's limiting groove 13 gradually increases along the column direction. Therefore, each bending section 222 in each column is distributed sequentially and independently in the insertion direction so as not to interfere with each other. Each bending section 222 passes through each limiting groove 13 along the column direction until the bending section 222 of each column protrudes out of the plastic body 1, at which point the ends are aligned in the insertion direction. The end of the bending section 222 that protrudes out of the plastic body 1 is used for soldering to the circuit board.

[0034] Compared with the prior art, the pluggable male connector of this utility model has the following advantages: by setting the plug-in cavity 12 on the plastic body 1, not only can the straight terminal 21 be inserted into it, but also the bent terminal 22 can be inserted into it, so that the plastic body 1 can be used for a variety of terminals, ensuring improved utilization of the plastic body 1, avoiding the need to specially design and manufacture the plastic body 1 when using the aforementioned different terminals, and reducing time and economic costs.
