Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to a control signal transmission connector and a connector pair. Background Art

[0002] A signal connector is a component used to connect electronic devices or circuits to transmit signals or electricity. The most common signal transmission connectors on the market today have several small square holes on the side. This hole-opening method requires that when the transmission connector is molded, sliders are set up at the upper and lower and left and right positions of the small square holes on the side of the connector to form a linkage mechanism to form the hole position. In this case, the mold structure setting will be more complicated, which will make the connector processing inconvenient and reduce the processing efficiency of the connector.

[0003] To this end, the utility model proposes a control signal transmission connector and a connector pair for solving the above-mentioned problems. Summary of the invention

[0004] The utility model aims to provide a control signal transmission connector and a connector pair, which can reduce the complexity of processing caused by opening a small square hole on the side of the connector, effectively improve the production and processing efficiency of the connector, and save resource costs.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A control signal transmission connector comprises: a connector body, the connector body comprising a plastic body, a plurality of cavities and a terminal group located in the cavities;

[0007] The plastic body is provided with an indicating arrow for indicating the insertion direction of the connector body, the terminal group includes a plurality of terminals parallel to each other, the number of the terminals is the same as the number of the cavities, and each of the cavities includes a plug-in section, a main section for placing the terminal, and a stop section for fixing the terminal;

[0008] The main section and the plug-in section in each cavity are connected in sequence in the direction of the indication arrow and pass through the connector body, the stop section and the plug-in section are located on the same side and their central axes are parallel to each other, one side of the stop section is connected to the main section, and the other side of the stop section is connected to the outside world.

[0009] By adopting the above technical solution, a stop section is set in the cavity inside the plastic body, and the terminal inside the plastic body is fixed by the stop section. The stop section is in the shape of a long strip. When opening the mold, it is only necessary to open the stop section along the direction of terminal placement to the end of one side of the plug-in section. There is no need to set a mold opening path perpendicular to the terminal placement direction, thereby improving the production and processing efficiency of the connector.

[0010] Preferably, the terminal comprises a terminal head, a terminal middle and a terminal tail in sequence, the terminal head is used for plugging, the terminal tail is used for wiring, and when the terminal is placed in the main section, the terminal head is close to the plug-in section.

[0011] By adopting the above technical solution, the direction in which the terminal is placed in the main body section is explained.

[0012] Preferably, an anti-retraction spring sheet is installed on one side of the middle portion of the terminal close to the stop segment, and the anti-retraction spring sheet is bent toward the stop segment, and the anti-retraction spring sheet is used to prevent the terminal from falling off.

[0013] By adopting the above technical solution, an anti-retraction spring sheet is arranged on the terminal to prevent the terminal from being separated from the connector body.

[0014] Preferably, when the terminal is inserted into the main section along the direction of the indication arrow, the anti-retraction spring sheet is pressed down by the plastic body in the opposite direction of the bending. When the terminal is placed in the main section, the anti-retraction spring sheet leaves the pressing of the plastic body and bounces up in the bending direction to the stop section.

[0015] By adopting the above technical solution, when the terminal is inserted into the main section, the bent anti-retraction spring sheet and the plastic main body can interact with each other to allow the terminal to be inserted smoothly. After insertion, the anti-retraction spring sheet bounces up and is stuck in the stop section to fix the terminal in the connector body.

[0016] Preferably, a stop groove is provided on one side of the stop section, and the side opposite to the stop groove is connected to the outside world, and the stop groove includes two outer arc surfaces and a stop plane, wherein the outer arc surface close to the main section is a first arc surface, and the outer arc surface close to the outside world is a second arc surface, and the stop plane is located between the first arc surface and the second arc surface, and the anti-retraction spring plate matches the stop groove.

[0017] By adopting the above technical scheme, a stop groove is set in the stop section to realize the anti-retraction function of the terminal, and the shape of the stop groove in the stop section is described in detail. The first arc surface facilitates the anti-retraction spring sheet to slide into the stop groove, and the stop plane facilitates the anti-retraction spring sheet to prevent the terminal from slipping off. The second arc surface limits the sliding distance of the anti-retraction spring sheet, so that the anti-retraction property of the terminal is more guaranteed.

[0018] Preferably, the plug-in section includes a first groove and a second groove, the first groove is connected to the outside, the second groove is located between the first groove and the main section, and the cross-section where the first groove connects with the second groove is smaller than the cross-section where the first groove connects with the outside.

[0019] By adopting the above technical solution, the cross-sectional sizes of the two ends of the first groove of the plug-in section are inconsistent, which has a guiding effect. Through the guiding effect of the first groove and then through the second groove, the accessory can be accurately inserted into the terminal head of the terminal.

[0020] Preferably, one side of the main body section away from the plug-in section is communicated with the outside, and the cross-section of the main body section communicated with the outside is larger than the cross-section of the other side.

[0021] By adopting the above technical solution, the cross section of one side of the main body section is larger than the other side, and the larger cross section is connected to the outside, so that the terminal can be inserted through the larger side and smoothly inserted into the plastic body.

[0022] Preferably, the connector body is also provided with an anti-misplugging structure for preventing mis-insertion.

[0023] By adopting the above technical solution, a fool-proof structure of the connector is provided to indicate the plug-in end of the connector to prevent mis-plugging.

[0024] Preferably, a plastic escape structure is respectively provided on both sides of the connector body.

[0025] By adopting the above technical solution and providing a material escape structure for the connector, the problem of shrinkage at this location during molding due to the thickness of the material at this location during production can be avoided.

[0026] A connector pair comprises a connector body and a mating connector engaged with the connector body.

[0027] In summary, the utility model has the following beneficial effects:

[0028] 1. The structure of the utility model opens the stop section in the cavity from the position of the stop groove to the opposite side of the stop groove to communicate with the outside world. Compared with the previous structure of only opening a small square hole, it is only necessary to set a mold in the direction of the indicating arrow to open the cavity of the stop section, and there is no need to add a mold perpendicular to the direction of the indicating arrow to form a linkage structure for grooving, which improves the grooving efficiency, saves the material of the connector, and saves the resource cost of the mold and the connector.

[0029] 2. The utility model sets the structure of the stop groove to a combination of two outer arc surfaces and a stop plane, so that one of the outer arc surfaces has a guiding function, and the other outer arc surface adds an extra layer of protection for the stop function, making it more functional.

In addition, the terms "first", "second", and the like are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features.

[0040] Reference Figures 1 to 4 A control signal transmission connector provided in this embodiment includes: a connector body 1, the connector body 1 includes a plastic body 2, a plurality of cavities 3 and a terminal group 4 located in the cavity 3.

[0041] An indicating arrow 5 for indicating the insertion direction of the connector body 1 is provided on the plastic body 2. In this embodiment, the indicating arrow 5 points to the side where the plug section is connected to the outside.

[0042] The terminal group 4 includes a plurality of terminals 6 which are parallel to each other. The number of the terminals 6 is the same as the number of the cavities 3. Each terminal 6 has a corresponding cavity and each terminal 6 is placed parallel to each other in the cavity.

[0043] Each cavity 3 includes a plug-in section 7, a main section 8 for placing the terminal 6, and a stop section 9 for fixing the terminal 6;

[0044] The main body section 8 and the plug section 7 in each cavity are connected in sequence in the direction of the arrow 5 and pass through the connector body 1. The stop section 9 and the plug section 7 are located on the same side and their central axes are parallel to each other. Figure 4 As shown, in this embodiment, the stop segment 9 has an opening on the plastic body 2 on the same side as the plug-in segment 7 , and the central axes of the plug-in segment 7 and the stop segment 9 are parallel but not overlapped.

[0045] One side of the stop section 9 is connected to the main body section 8, and the other side of the stop section 9 is connected to the outside.

[0046] like Figure 5 As shown, the terminal 6 includes a terminal head 61, a terminal middle part 62 and a terminal tail 63 in sequence, which has the same function as the existing terminal 6: the terminal head 61 is used for plugging with a matching part, and the terminal tail 63 is used for wiring.

[0047] Reference Figure 4 and Figure 5 When the terminal 6 is placed in the main body section 8, the terminal head 61 is close to the plug section 7. The upper and lower rows of terminals 6 in this embodiment are arranged in a mirror-symmetrical manner.

[0048] An anti-retraction spring sheet 64 is installed on one side of the terminal middle portion 62 close to the stop segment 9 . The anti-retraction spring sheet 64 is bent toward the stop segment 9 . The anti-retraction spring sheet 64 is used to prevent the terminal 6 from falling off.

[0049] When the terminal 6 is inserted into the main section 8 along the direction of the arrow 5, Figure 5 When the terminal 6 is inserted in the placement orientation, the anti-retraction spring piece 64 is pressed down by the plastic body 2 in the opposite direction of the bend. When the terminal 6 is successfully inserted into the main body section 8, the anti-retraction spring piece 64 leaves the pressing of the plastic body 2 and bounces up in the direction of the bend to the stop section 9. At this time, the state is as follows Figure 4 As shown, a stop groove 10 is provided on one side of the stop section 9, and the anti-retraction spring 64 is inserted into the stop groove 10 to prevent the terminal 6 from sliding in the opposite direction of the indicating arrow 5, that is, toward the terminal tail 63 and falling off.

[0050] The side opposite to the stop groove 10 is connected to the outside. Figure 4 As shown, in this embodiment, the side of the stop segment 9 away from the terminal 6 is connected to the outside world, the side where the stop groove 10 is located is perpendicular to the direction of the indicator arrow 5, and the side opposite to the stop groove 10 is connected to the outside world, that is, the range of the cavity slot of the stop segment 9 is directly opened from the stop groove 10 along the direction of the indicator arrow 5 and the side opposite to the stop groove 10. When the mold is used to slot the stop segment, the slider along the direction of the indicator arrow 5 is directly used to slot once. Compared with the processing method of not opening the side opposite to the stop groove 10 and only opening a hole, the mold of this structure does not need to set the slider side core pulling in the direction perpendicular to the indicator arrow 5, which simplifies the slider linkage mechanism set when opening the hole, which is equivalent to reducing the processing on one side and can double the processing efficiency.

[0051] like Figure 6 As shown, the stop groove 10 includes two outer arc surfaces and a stop plane 101, wherein the outer arc surface close to the main section 8 is the first arc surface 102, and the outer arc surface close to the outside is the second arc surface 103, the stop plane 101 is located between the first arc surface 102 and the second arc surface 103, and the anti-retraction spring plate 64 matches the stop groove 10.

[0052] When the anti-retraction spring piece 64 pops up and gets stuck into the stop groove 10, the anti-retraction spring piece 64 first slides into the stop groove 10 through the first arc surface 102. If the terminal 6 continues to slide toward the terminal tail 63, the anti-retraction spring piece 64 will abut against the stop plane 101. The second arc surface 103 is located on the other side of the stop plane 101, which can limit the sliding range of the anti-retraction spring piece 64, making the stop and anti-retraction function of the stop groove 10 more secure.

[0053] In this embodiment, when the terminal 6 is placed in the plastic body 2, it is sometimes subjected to a pulling force from the terminal head 61 to the terminal tail 63 during use, and the anti-retraction spring sheet 64 will tilt up. The structure of the second arc surface 103 can prevent the anti-retraction spring sheet 64 from continuing to tilt up. To prevent the anti-retraction spring sheet 64 from structural failure, the ability of the anti-retraction spring sheet 64 to resist pulling out is increased to improve the holding force of the terminal 6.

[0054] like Figure 4 As shown, the plug-in section 7 includes a first groove 71 and a second groove 72. The first groove 71 is connected to the outside, and the second groove 72 is located between the first groove 71 and the main section 8. The cross-section where the first groove 71 and the second groove 72 meet is smaller than the cross-section where the first groove 71 meets the outside.

[0055] Therefore, the first groove 71 has a guiding function. The parts used in conjunction with the connector body 1 of the utility model enter the second groove 72 through the guiding function of the first groove 71. The second groove 72 is connected to the terminal head 61, and the parts can be smoothly inserted into the terminal head 61 through the second groove 72.

[0056] One side of the main body section 8 away from the plug-in section 7 is communicated with the outside, and the cross section of the main body section 8 communicated with the outside is larger than the cross section of the other side.

[0057] That is, when the terminal 6 is placed in the main body section 8, the cross-section of the side of the main body section 8 close to the terminal tail 63 of the terminal 6 is larger than the cross-section of the side close to the terminal head 61. Therefore, the terminal 6 can be inserted into the main body section 8 from the larger cross-section side to the smaller cross-section side. For this reason, if there is no anti-retraction spring sheet 64 to abut against the stop section 9, the terminal 6 will slide out of the main body section 8 in the direction of the terminal tail 63.

[0058] The connector body 1 is also provided with a foolproof structure 11 for preventing mis-insertion. The foolproof structure 11 in this embodiment is located on the same side of the connector body 1 as the indicator arrow 5, and one edge of the foolproof structure 11 is flush with the edge of the plug section 7. When inserting the mating part, the foolproof structure 11 is on top and inserted in the direction of the indicator arrow 5.

[0059] A plastic material escape structure 12 is provided on both sides of the connector body 1, which is perpendicular to the foolproof structure 11 and adjacent to the opening side of the first groove 71. Each plastic material escape structure 12 includes a through groove parallel to the direction indicated by the indicator arrow 5. The material on both sides is thick, and the plastic material escape structure 12 can avoid shrinkage problems that may occur on both sides during production and molding.

[0060] This embodiment further provides a connector pair, including: a connector body 1 and a mating connector 13 engaged with the connector body 1 .

[0061] In summary, the utility model provides a control signal transmission connector and a connector pair, which improves the hole-shaped stop segment 9 that originally needs to be opened by the mold linkage mechanism by setting the stop segment 9 in the connector body 1 as a groove that is directly opened to the adjacent side surface, thereby improving the efficiency of mold opening. For example, before the improvement, only 4 stop segments 9 could be opened, but after the improvement, at most 8 stop segments can be opened, thereby reducing the complexity of the mold and also reducing the cost of the mold; at the same time, the volume of the cavity 3 of the stop segment 9 of the connector body 1 is increased, thereby saving the material cost of the connector body 1; finally, the structure of the stop groove 10 in the stop segment 9 is improved, so that the stop and anti-retreat function is further guaranteed.

[0062] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
