Description

Technical Field

[0001] This utility model relates to the field of electrical connector repair, and in particular to a connector with a point-by-point self-test function. Background Technology

[0002] During installation, existing electrical connectors require stripping out the multiple independent electrical cores contained in the wire harness and making reliable electrical connections with the corresponding contacts inside the connector (usually by welding, crimping, or screw fixing). When the connector is plugged into the mating socket, the current is transmitted to the socket through each contact, thus achieving circuit conduction.

[0003] However, when connection problems occur during subsequent use (such as signal interruption), a troubleshooting problem arises. When a fault occurs, it is necessary to check whether the battery cells and contacts are conducting current normally. By using testing tools (such as a multimeter), the conduction current status of each set of battery cells and their corresponding contacts is tested and checked one by one. This "point-by-point testing" fault location method is extremely inefficient, especially for connectors with a large number of cores, which significantly increases the downtime for maintenance and results in low maintenance efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a connector with a point-by-point self-test function, which can accurately locate a group of contacts that have failed through a prompting mechanism, thereby improving maintenance efficiency.

[0005] The technical solution adopted by the connector with point-by-point self-test function disclosed in this utility model is:

[0006] The device includes a main body, within which a core is installed. Multiple contacts are fixedly connected to the core, and terminals are electrically connected to the contacts. A prompting mechanism is provided on the main body, and the prompting mechanism is electrically connected to the contacts. The prompting mechanism is used to monitor whether the contacts are energized.

[0007] As a preferred embodiment, the indicator mechanism includes an indicator light electrically connected to the contact element, and the insert is provided with an inductor coil electrically connected to the indicator light.

[0008] As a preferred embodiment, the main body includes a housing, the insert is snapped into the housing, and the indicator light extends out of the housing and is fixedly connected thereto.

[0009] As a preferred embodiment, one end of the contact has a mating hole, and the other end of the terminal is inserted into the mating hole of the contact.

[0010] As a preferred embodiment, the insert has multiple through holes, the contact is placed in the through holes, the insert has mounting holes corresponding to the through holes, the mounting holes are connected to the through holes, and a fastener is provided in the mounting hole, the fastener is inserted into the mating hole and tightens the outside of the terminal.

[0011] As a preferred embodiment, the insert has a slot, the through hole is located in the slot, and the other end of the contact extends into the slot.

[0012] The beneficial effects of the connector with point-by-point self-test function disclosed in this utility model are:

[0013] After the multiple independent cells of the wire harness are electrically connected to multiple terminals, the terminals are then electrically connected to the contacts, and the insert is installed inside the main body. Since the indicator mechanism is electrically connected to the contacts, and the contacts are electrically connected to the terminals, it is possible to monitor whether each contact is conducting current simultaneously. When one of the cells fails, causing the corresponding contact to have no current conduction, maintenance personnel can accurately locate the faulty cell and the corresponding contact based on the indicator mechanism, without having to check all contacts one by one, which significantly improves maintenance efficiency.

[0018] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0019] Please refer to Figure 1 and Figure 2 .

[0020] This utility model discloses a connector with point-by-point self-testing function, comprising a main body 1;

[0021] The main body 1 includes an outer shell 2; the outer shell 2 is provided with a limiting member 21. In this embodiment, it is preferred that there are two limiting members 21 in the outer shell 2. The two limiting members 21 in the outer shell 2 are respectively close to the two ends of the outer shell 2. The limiting members 21 are fixed to the inner wall of the outer shell 2 by bolts.

[0022] Furthermore, a spring piece 211 extends from the limiting member 21. In this embodiment, it is preferred that there are two spring pieces 211 on the limiting member 21, with the two spring pieces 211 respectively close to the two sides of the limiting member 21.

[0023] The main body 1 is equipped with a core 3, and the core 3 has a slot 31. In this embodiment, it is preferred that there are four slots 31 on the core 3, and the four slots 31 are located at both ends of the core 3 respectively.

[0024] The outer shell 2 is fitted on the outside of the insert 3. The two limiting members 21 inside the outer shell 2 are located at both ends of the insert 3. The spring piece 211 inside the outer shell 2 is inserted into the slot 31 on the adjacent insert 3 for fixation. The outer shell 2 constrains the insert 3 inside the outer shell 2 through the limiting members 21.

[0025] Please refer to Figure 1 , Figure 3 and Figure 4 .

[0026] In this embodiment, the bottom of the insert 3 is preferably provided with a slot 32, and the insert 3 has multiple through holes 33. One end of the through hole 33 is located at the top of the insert 3, and the other end of the through hole 33 is located in the slot 32. The multiple through holes 33 are arranged at intervals on the top of the insert 3. In this embodiment, the multiple through holes 33 are preferably arranged in two rows.

[0027] Furthermore, an annular step extends inside the through hole 33, making the diameter of one end of the through hole 33 larger than the diameter of the other end of the through hole 33;

[0028] Furthermore, the insert 3 has mounting holes 331 corresponding to the number of through holes 33. In this embodiment, it is preferred that multiple mounting holes 331 are arranged in two rows located on both sides of the insert 3. The mounting holes 331 are connected to the through holes 33, and fasteners 332 are provided in the mounting holes 331. In this embodiment, it is preferred that the fasteners 332 are screws.

[0029] Multiple contact elements 34 are fixedly connected to the insert 3. One end of the contact element 34 is provided with a mating hole 341, and the outer side of the contact element 34 is provided with a threaded hole, which communicates with the mating hole 341.

[0030] Furthermore, the contact 34 is placed inside the through hole 33, with the middle part of the contact 34 abutting the annular step, and the other end of the contact 34 extending through the annular step into the slot 32; the fastener 332 is inserted into the through hole 33 and connected with the threaded hole, and the contact 34 is constrained in the through hole 33 by the fastener 332 and the annular step, so that the contact 34 cannot move along the axial direction of the through hole 33.

[0031] The main body 1 is provided with a prompting mechanism 4, which is electrically connected to the contact element 34;

[0032] Furthermore, the indicator mechanism 4 includes an indicator light 41 electrically connected to the contact 34. The indicator light 41 is electrically connected to one end of the contact 34 via a wire. In this embodiment, the indicator light 41 is preferably a pulsed dot-shaped light-emitting diode. The indicator light 41 extends out of the housing 2 and is fixedly connected to the housing 2. Multiple indicator lights 41 are arranged at intervals on the housing 2. In this embodiment, multiple indicator lights 41 are preferably arranged in two rows, so that the position of the indicator light 41 corresponds to the position of the contact 34 electrically connected to it on the core 3, allowing maintenance personnel to more accurately locate the faulty wire harness cell and the corresponding contact 34.

[0033] Furthermore, the insert 3 is provided with an inductor coil that is electrically connected to the indicator light 41, and the indicator light 41 is electrically connected to the inductor coil via a cable;

[0034] Since the diode of the indicator light 41 has unidirectional conductivity, it needs to be rectified by an inductor coil to a voltage and current suitable for lighting the indicator light 41, and the pulsating DC needs to be smoothed; when the contact 34 conducts current, it simultaneously supplies power to the indicator light 41 to light it up.

[0035] The contact 34 is electrically connected to a terminal 35. The wire harness passes through the housing 2, and multiple independent battery cells of the wire harness are electrically connected to one end of multiple terminals 35 respectively. The other end of the terminal 35 is inserted into the mating hole 341 of the contact 34. The fastener 332 passes through the mating hole 341 and presses against the outside of the terminal 35. The fastener 332 uses the friction force of contact with it to constrain the terminal 35 to the contact 34, so that the terminal 35 cannot move along the axial direction of the mating hole 341. The battery cell conducts current to the contact 34 through the terminal 35.

[0036] Please refer to Figures 1-4 .

[0037] When using:

[0038] When the ferrule 3 is plugged into the matching external socket, multiple cells transmit current to the external socket via the contact 34 connected thereto.

[0039] When the battery cell normally conducts current to the external socket through the contact 34, the current carried by the contact 34 will simultaneously power the indicator light 41, thus illuminating the indicator light; when the battery cell fails or the connection between the battery cell and the contact 34 is abnormal, causing the current to be interrupted, the contact 34 loses power and the indicator light 41 goes out; by observing the on / off state of the indicator light 41, maintenance personnel can quickly and accurately locate the faulty battery cell and its corresponding contact 34.

[0040] This invention provides a connector with a point-by-point self-test function. After multiple independent battery cells of the wire harness are electrically connected to multiple terminals, the terminals are then electrically connected to contacts, and the ferrule is installed inside the main body. Since the prompting mechanism is electrically connected to the contacts, and the contacts are electrically connected to the terminals, it is possible to simultaneously monitor whether each contact is conducting current. When one of the battery cells fails, causing the corresponding contact to have no current conduction, maintenance personnel can accurately locate the faulty battery cell and the corresponding contact based on the prompting mechanism, without having to test all contacts one by one, significantly improving maintenance efficiency.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
