[0043] In order to make the technical problems, technical schemes and beneficial effects to be solved by the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Therefore, one feature mentioned in the specification is used to explain one feature of one embodiment of the utility model, and it is not implied that each embodiment of the utility model must have the explained feature. In addition, it should be noted that the specification describes many features. Although certain features can be combined together to show possible system designs, these features can also be used in other combinations that are not explicitly described. Therefore, unless otherwise stated, the explained combination is not intended to be limited.

[0044] The principles and structures of the utility model will be described in detail below in combination with the drawings and embodiments.

[0045] Embodiment 1

[0046] With reference to the drawings Figures 1-2 The utility model provides a common pressure needle seat, including needle seat body 10, at least one end of opposite two sides of needle seat body 10 extends outward and forms buckle 101, and buckle 101 is located at the same end of both sides of needle seat body 10;

[0047] The two sides of needle seat body 10 are provided with a plurality of limiting holes 102 that pass through itself corresponding to buckle 101, a plug pin 20 is matched and arranged in each limiting hole 102, and the two ends of plug pin 20 respectively stretch out from the two sides of needle seat body 10;

[0048] When buckle 101 is matched and connected with the connector 301 of one end of wire harness 30, the plug pin 20 corresponding to buckle 101 can be matched and inserted into connector 301, so that connector 301 is electrically connected with needle seat body 10.

[0049] It should be noted that four limiting holes 102 are taken as an example in the embodiment, that is, four limiting holes 102 that pass through itself are arranged on the two sides of needle seat body 10 corresponding to buckle 101, and one plug pin 20 is matched and inserted into each limiting hole 102.

[0050] It should be noted that the connector 301 of the wire harness 30 in the embodiment includes a 2P connector and a 4P connector, wherein the 2P connector indicates that the connector 301 has only two contacts in contact with the pins 20, and the 4P connector indicates that the connector 301 has only four contacts in contact with the pins 20.

[0051] In this way, when the wire harness 30 needs to be extended, and the connector 301 of the wire harness 30 is a 2P connector, the 2P connectors of the two wire harnesses are respectively buckled with the buckles 101 at the same end of the two sides of the needle base body 10, and the two pins 20 located in the middle are correspondingly inserted into the 2P connectors and connected with the corresponding contacts one by one, so as to realize the extension of the wire harness 30.

[0052] When the wire harness 30 needs to be co-pressed and expanded, the buckle 101 at one end of one side of the needle base body 10 is buckled with the 2P connector of one wire harness 30, and the two pins 20 located at one side and in the middle are correspondingly inserted into the 2P connector and connected with the corresponding contacts one by one; at the same time, the buckle 101 at the same end of the other side of the needle base body 10 is buckled with the 4P connector of the other wire harness 30, and the four pins 20 located at the other side are correspondingly inserted into the 4P connector and connected with the corresponding contacts one by one, so as to realize the co-pressed expansion of the wire harness 30.

[0053] Therefore, the co-pressed needle base can not only extend the length of the wire harness 30, but also enable the wire harness 30 to be co-pressed and expanded without damaging the integrity of the wire harness sheath, without the need to use wire stripping and welding to realize the extension of the wire harness 30 and the co-pressed expansion of the wire harness 30, thereby avoiding the situation that the service life of the wire harness 30 is greatly reduced due to wire stripping, reducing the risk of electric shock, especially in high-voltage or large-current applications; and can improve the versatility of the co-pressed needle base, and can flexibly adapt to various application scenarios; can improve the compatibility of the co-pressed needle base, and can be compatible with multi-pin connectors or other standardized interfaces, reducing the need for additional adapters or converters; can improve the expansibility of the co-pressed needle base, providing more connection options without increasing additional hardware, improving the expansibility and flexibility of the co-pressed needle base; and can also avoid the situation that the exposed core of the wire harness 30 is more susceptible to external electromagnetic field interference after wire stripping, affecting the stability and quality of signal transmission.

[0054] In order to ensure that the needle base body 10 has better fault tolerance and flexibility, more connection options are realized on one co-pressed needle base, and different wiring requirements are adapted, with reference to the accompanying drawings Figure 1 The two ends of the opposite two sides of the needle base body 10 extend outward to form buckles 101.

[0055] It should be noted that the two ends on one side of the needle holder body 10 are end A and end B, and the two ends on the opposite side of the needle holder body 10 are end C and end D. End A and end C are the same end on the opposite sides of the needle holder body 10. Similarly, end B and end D are also the same end on the opposite sides of the needle holder body 10. The buckles 101 located at ends A, B, C and D of the needle holder body 10 are each provided with a set of limiting holes 102. Each set of limiting holes 102 includes four limiting holes 102.

[0056] When the connectors 301 connected to the A and C ends on opposite sides of the pin holder body 10 malfunction due to some accident and are inconvenient to remove from the pins 20, the user can cut off the pins 20 corresponding to the A and C ends of the pin holder body 10 to detach the connectors 301 from the pin holder body 10. Then, the connectors 301 of the same type of wire harness 30 are respectively snapped into the C and D ends of the pin holder body 10, and the pins 20 corresponding to the C and D ends of the pin holder body 10 are inserted into the connectors 301 of the wire harness 30 and make contact with the contacts to complete the extension or co-pressure expansion of the wire harness 30.

[0057] To ensure that the pins 20 corresponding to each clip 101 can connect to the connectors 301 of the wire harness 30 more effectively and flexibly, please refer to the attached document. Figures 4-5 The needle holder body 10 has multiple limiting holes 102 on both sides corresponding to the buckle 101, and the multiple limiting holes 102 corresponding to each buckle 101 are in the same straight line.

[0058] To ensure that the pin 20 can be more securely installed in the corresponding limiting hole 102, refer to the attached document. Figure 5 Each of the limiting holes 102 has a corresponding protrusion 103 extending inward from the middle of the opposite sides, and there is a gap 104 between the two protrusions 103; the gap 104 facilitates the insertion of the needle 20 from the limiting hole 102 on one side of the needle holder body 10 and the extension from the corresponding limiting hole 102 on the other side of the needle holder body 10.

[0059] The pin 20 is provided with a matching recess (not shown, same throughout) corresponding to the boss 103.

[0060] Thus, when it is necessary to insert the pin 20 into the corresponding limiting hole 102, first insert one end of the pin 20 into the limiting hole 102, and then slowly push the pin 20 into the limiting hole 102 until the concave platform of the pin 20 matches and engages with the protrusion 103 in the limiting hole 102. At this time, even if you push the pin 20 with force, the pin 20 cannot be pushed.

[0061] It should be noted that the limiting hole 102 proposed in this embodiment is in the shape of an "I" shaped hole.

[0062] Of course, in other embodiments, the pins 20 can also be fixed on the socket body 10 and extend from opposite sides of the socket body 10.

[0063] Wherein, referring to the accompanying drawings Figure 2 , the number of the limiting holes 102 is plural, and the limiting holes 102 on the same side of the two sides of the socket body 10 form a group with two, and the first conductive metal sheet 105 is arranged between the limiting holes 102 of each group to form an electrical connection between the pins 20 of each group.

[0064] It should be noted that the pins 20 in the four limiting holes 102 corresponding to the A end and the D end are sequentially the first pin, the second pin, the third pin and the fourth pin from left to right; and the pins 20 in the four limiting holes 102 corresponding to the B end and the C end are sequentially the first pin, the second pin, the third pin and the fourth pin from right to left. And the first pin and the second pin, and the third pin and the fourth pin of the A end and the C end are each provided with a first conductive metal sheet 105; similarly, the first pin and the second pin, and the third pin and the fourth pin of the B end and the D end are each provided with a first conductive metal sheet 105.

[0065] Specifically, if the selected wire harness 30 is too large due to improper selection of the wire harness 30, the connector 301 of the wire harness 30 cannot be co-pressed and crimped with multiple wire harnesses 30, resulting in the need to co-press and expand the wire harness 30, referring to the accompanying drawings Figures 8-9 , the 2P connector of the wire harness 30 is expanded to a 4P connector, and the A end and the C end of the socket body 10 are taken as an example. The user needs to pull out the pins 20 corresponding to the B end and the D end of the socket body 10 to prevent the connector 301 of the wire harness 30 from being unable to connect with the pins 20 of the A end;

[0066] The 2P connector is clamped with the buckle 101 of the A end, and the second pin and the third pin corresponding to the A end are inserted into the 2P connector and connected with the corresponding contacts one by one; at the same time, the buckle 101 of the C end of the socket body 10 is clamped with the 4P connector, and the four pins 20 corresponding to the C end are inserted into the 4P connector and connected with the corresponding contacts one by one, thereby realizing the co-pressed expansion of the wire harness 30. In order to better connect the 2P connector with the buckle 101 of the A end, the user can cut off the first pin and the fourth pin of the A end to prevent affecting the connection of the 2P connector with the buckle 101 of the A end.

[0067] If the wire harness 30 data derived during three-dimensional simulation wiring is not properly set due to parameters such as wire harness 30 bending radius, or the wiring is not considered in actual conditions, resulting in insufficient wire length, the wire harness 30 needs to be lengthened, referring to the accompanying drawings Figures 6-7In this embodiment, two 2P connectors of the wire harness 30 are connected to extend the wire harness 30. At this time, the two 2P connectors are inserted into the buckles 101 of the A end and the C end, and the second pins and the third pins corresponding to the A end and the C end are connected to the contacts of the 2P connectors one by one, so as to realize the extension of the wire harness 30. In order to enable the 2P connectors to be better connected with the buckles 101 of the A end and the C end, the user can cut off the first pins and the fourth pins of the A end and the C end to prevent affecting the connection of the 2P connectors with the buckles 101 of the A end and the C end.

[0068] Similarly, a second conductive metal sheet (not shown, the same throughout) is arranged between a group of limiting holes 102 corresponding to the two ends of each side of the needle base body 10, so that a group of pins 20 at one end of each side of the needle base body 10 is electrically connected with a group of pins 20 corresponding to the other end.

[0069] In this way, when the A end and the C end of the needle base body 10 are connected with the connectors 301 of one wire harness 30, if the connector 301 connected with the C end fails due to some accident and cannot be detached from the pins 20, the pins 20 connected with the C end can be cut off at this time, so that the connector 301 connected with the C end is separated from the C end, and then a connector 301 of the same type as the C end is connected with the B end (i.e., the pins 20 corresponding to the B end are in correct contact with the connector 301), so as to complete the adjustment of the wire harness 30 without replacing the entire common pressure needle base, thereby improving the versatility and expansibility of the common pressure needle base.

[0070] Preferably, the first conductive metal sheet 105 and the second conductive metal sheet are completely wrapped by the needle base body 10, so as to prevent the first conductive metal sheet 105 and the second conductive metal sheet from being contacted with the outside world and causing leakage, electromagnetic interference, etc.

[0071] Preferably, the limiting member 201 is a thin metal sheet. Figure 3 Preferably, each pin 20 is provided with a limiting member 201 in the recess towards the corresponding first conductive metal sheet 105.

[0072] Preferably, the limiting member 201 is a thin metal sheet.

[0073] In this way, when the pin 20 is inserted into the corresponding limiting hole 102, the pin 20 gradually moves into the limiting hole 102 until the limiting member 201 abuts against the corresponding first conductive metal sheet 105 and forms a limit, so that the pin 20 can be more stably installed in the corresponding limiting hole 102.

[0074] Preferably, the limiting member 201 is located at a first preset distance from the midpoint of the pin 20, so as to further enable the pin 20 to be more stably installed in the corresponding limiting hole 102.

[0075] It should be noted that the first preset distance is in the range of [1.5mm, 1.8mm].

[0076] For the convenience of understanding, the thickness of the needle seat body 10 is selected as 3.6mm, and the thickness here refers to the length of the needle seat body 10 along the length direction of the insertion needle 20, and then the first preset distance is preferably 1.6mm, so that when the insertion needle 20 needs to be inserted into the corresponding limiting hole 102, the end of the insertion needle 20 far away from the limiting piece 201 is inserted into the limiting hole 102 first, so that when the lengths of the insertion needle 20 extending from the opposite sides of the needle seat body 10 are the same, the limiting piece 201 will abut against the corresponding first conductive metal sheet 105 and form a limit.

[0077] Embodiment 2

[0078] The utility model discloses still propose a kind of multicore connector, the multicore connector includes at least one above-mentioned co-pressing needle seat.

[0079] When the wiring harness 30 needs to be extended, and the connectors 301 of the wiring harness 30 are all 2P connectors, referring to the accompanying drawings Figures 6-7 , the 2P connectors of the two wiring harnesses are respectively clamped with the buckles 101 of the A end and the C end (or the B end) of the needle seat body 10, and the second insertion needle and the third insertion needle located in the middle are inserted into the 2P connectors and connected with the contacts one by one, so as to realize the extension of the wiring harness 30.

[0080] When the 2P connectors of the wiring harness 30 are expanded to 4P connectors to realize the co-pressing expansion of the wiring harness 30, referring to the accompanying drawings Figures 8-9 , the buckle 101 of the A end of the needle seat body 10 is clamped with the 2P connector of one wiring harness 30, and the second insertion needle and the third insertion needle corresponding to the A end are inserted into the 2P connector and connected with the contacts one by one; at the same time, the buckle 101 of the C end (or the B end) of the needle seat body 10 is clamped with the 4P connector of another wiring harness 30, and the four insertion needles 20 corresponding to the C end (or the B end) are inserted into the 4P connector and connected with the contacts one by one, so as to realize the co-pressing expansion of the wiring harness 30.

[0081] Therefore, the common pressure needle base can not only extend the length of the wire harness 30, but also make the wire harness 30 expand under common pressure without damaging the integrity of the wire harness sheath, without using the wire stripping and welding method to realize the lengthening and common pressure expansion of the wire harness 30, thereby avoiding the case that the service life of the wire harness 30 is greatly reduced due to wire stripping, reducing the risk of electric shock of the common pressure needle base, especially in high voltage or large current applications, and improving the versatility of the multi-core connector, which can flexibly adapt to various application scenarios, and also improving the compatibility of the multi-core connector, which can be compatible with multi-pin connectors or other standardized interfaces, reducing the need for additional adapters or converters, and also improving the expansibility of the multi-core connector, providing more connection options without increasing additional hardware, improving the expansibility and flexibility of the multi-core connector, and also avoiding the case that the wire harness 30 is more susceptible to external electromagnetic field interference after the exposed core is exposed, affecting the stability and quality of signal transmission.

[0082] Obviously, the above-described embodiments are only a part of the embodiments of the present application, not all the embodiments, and the preferred embodiments of the present application are given in the drawings, but do not limit the patent scope of the present application. The present application can be realized in many different forms, and conversely, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.
