Description

Technical Field

[0001] The present invention belongs to the technical field of detection devices, and particularly relates to a detection device for the electrical performance of metal connectors. Background Art

[0002] A plug-in part mainly refers to a connection tool for electrical signal interaction between different devices or circuits. Its main structure is as Figure 1 shown, including two plug heads 5 and a wire harness 51 connecting the two plug heads 5. Before the plug-in part is put on the market, it is often necessary to detect whether its electrical performance is conductive and normal. At present, the common detection methods mostly involve manually connecting the plug heads and then testing, and then removing them after completion. Such a method has a long test preparation time and a long waiting time, and it is difficult to meet the production efficiency requirements for industrial production. At present, some detection means also use robotic arms for operation. Although such detection methods reduce the intervention of manual labor, the continuity of such methods is still not high. Summary of the Invention

[0003] The purpose of the present invention is to provide a detection device for the electrical performance of metal connectors to solve the problems mentioned in the background art.

[0004] To achieve the above technical purpose, the technical solution adopted by the present invention is as follows:

[0005] A detection device for the electrical performance of metal connectors, including a base, a detection plug, and a control panel. The detection plug is installed on a bracket and is electrically connected to an external detection device through a wire harness. An installation mechanism matching the detection plug is provided at the upper end of the base;

[0006] The installation mechanism includes a platform, a transmission shaft, an outer sleeve, and a plurality of traction devices. The transmission shaft is concentrically connected to the platform and rotates on the upper end of the base.

A plurality of positioning grooves equal in number to the traction devices are formed at the upper end of the platform. The traction devices are arranged between the base and the platform, and the plurality of traction devices correspond to the plurality of positioning grooves one by one.

[0007] The positioning groove includes a fixing groove and a wire clamping groove. The fixing groove matches the shape and structure of the base part of the plug-in part. The size of the wire clamping groove matches the size of the wire harness of the plug-in part and extends through the middle of the fixing groove to the outside of the platform. The wire clamping groove penetrates the upper and lower ends of the platform.

[0008] The tractor includes a guide rod, a traction body, and a guide head. A turntable concentric with the transmission shaft is rotatably provided at the upper end of the base. The guide rod is fixedly provided between the turntable and the platform. The traction body is slidably connected to the guide rod up and down. The guide head is provided on the traction body. A guide groove matching the guide head is formed on the side of the outer sleeve. The guide groove includes a C-shaped groove portion and a V-shaped groove portion connected end to end. The C-shaped groove portion is parallel to the ground and is located on the side close to the platform, and the V-shaped groove portion is perpendicular to the ground and is located on the side close to the detection plug.

Specific embodiments

[0023] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the drawings and embodiments.

[0024] As Figures 1-6 shown, a device for detecting the electrical performance of a metal connector includes a base 1, a detection plug 11 and a control panel. The detection plug 11 is installed on the bracket 12 and is electrically connected to an external detection device through a wire harness. An installation mechanism matching the detection plug 11 is provided at the upper end of the base 1;

[0025] The installation mechanism includes a platform 2, a transmission shaft 21, an outer sleeve 3 and a plurality of traction devices. The transmission shaft 21 is concentrically connected to the platform 2 and is rotatably arranged at the upper end of the base 1. The outer sleeve 3 is concentrically sleeved on the transmission shaft 21 and is fixedly connected to the base 1. A plurality of positioning grooves equal in number to the traction devices are formed at the upper end of the platform 2. The traction devices are arranged between the base 1 and the platform 2, and the plurality of traction devices correspond to the plurality of positioning grooves one by one.

[0026] When detecting the electrical performance of the plug-in connector, one of the plugs of the plug-in connector is installed in the positioning groove of the platform 2 by means of manual or external mechanical facilities, etc., so that one of the plugs is fixed. Subsequently, the transmission shaft 21 can be driven by an external transmission facility such as a motor through the control panel, and then the platform 2 rotates to switch to the next positioning groove. On the one hand, it meets the need for intermittent feeding, on the other hand, it meets the need for intermittent switching of detection, and at the same time improves the continuous synchronization of feeding and detection. The control panel refers to any one with a control function such as a single-chip microcomputer and a timing circuit, which is used to control the intermittent opening and closing of the motor and the detection of the detection plug 11. Its control means and methods are well-known and understandable or replaceable by those skilled in the art, so no more details will be given here;

[0027] When the platform 2 moves from the feeding side to the position of the detection plug 11, the traction device will stretch and pull the unfixed end of the plug-in connector, so that its wire harness is straightened and the other plug is fixed. At this time, the positions of the two plugs do not move and the wire harness is straightened, so as to meet the need for the detection plug 11 to detect the conductivity of the plug-in connector. In this way, during the detection and feeding processes, the production detection effect can be effectively improved, and the manual fixing time of feeding and the detection waiting time can be reduced.

[0028] The positioning groove includes a fixing groove 22 and a wire clamping groove 23. The fixing groove 22 matches the shape and structure of part of the base 1 of the plug-in connector. The size of the wire clamping groove 23 matches the size of the wire harness of the plug-in connector and extends through from the middle of the fixing groove 22 to the outside of the platform 2. The wire clamping groove 23 penetrates through the upper and lower ends of the platform 2.

[0029] The fixing groove 22 is used to limit and fix the plug part of the plug-in connector, and anti-slip materials or elastic materials such as silica gel, sponge, friction pads, etc. are provided on the inner wall of the fixing groove 22, which can further improve the fixing effect on the plug. The wire clamping groove 23 is used to limit the position of the wire connecting between two plugs.

[0030] The tractor includes a guide rod 4, a traction body 41 and a guide head 42. A turntable 421 concentric with the transmission shaft 21 is rotatably provided at the upper end of the base 1. The guide rod 4 is fixedly arranged between the turntable 421 and the platform 2. The traction body 41 is slidably connected with the guide rod 4 up and down. The guide head 42 is arranged on the traction body 41. A guide groove matching with the guide head 42 is opened on the side of the outer sleeve 3. The guide groove includes a C-shaped groove part 43 and a V-shaped groove part 44 connected end to end. The C-shaped groove part 43 is parallel to the ground and is located on the side close to the platform 2, and the V-shaped groove part 44 is perpendicular to the ground and is located on the side close to the detection plug 11.

[0031] The traction body 41 is also provided with a positioning groove matching with the plug-in connector. The opening of the fixing groove 22 of the traction body 41 faces downward, and the opening of the fixing groove 22 of the platform 2 faces upward.

[0032] During the movement of the platform 2, the guide head 42 on the traction body 41 is in the guide groove and slides in the guide groove along with the movement of the platform 2. Among them, the C-shaped groove part 43 matches the area of the platform 2 that does not correspond to the detection plug 11. At this time, the two plugs of the plug-in connector are in an adjacent state, and the wire harness is not straightened, so as to meet the needs of loading and unloading. When the positioning groove on the platform 2 gradually corresponds to the area of the detection plug 11, at this time, the guide head 42 of the traction body 41 gradually corresponds to the V-shaped groove part 44. The downward movement of the traction body 41 will be caused by the guidance of the V-shaped groove part 44. Thus, the two plugs are pulled apart by the traction body 41. At this time, the wire harness is straightened, and the two plugs respectively fall into the corresponding fixing grooves 22. Since the wire harness is straightened and the fixing groove 22 has a certain depth, the plug cannot be taken out by upward pulling or gravity at this time. Therefore, the plug-in connector has good stability at this time;

[0033] At this time, the detection plug 11 can perform electrical performance detection on the connection of the plug through an external lifting component such as an electric control telescopic rod, a hydraulic rod or a guide rail. After the detection is completed, in order to avoid excessive friction during connection and cause excessive tension on the wire harness when separating and damage the plug-in connector, corresponding anti-pushing components or fixing components can also be set, such as a clamping plate, a baffle plate, and another telescopic component to fix the position of the plug, so as to achieve the effect of stable separation, and finally complete the detection.

[0034] A guiding cover 45 is provided at the opening of the positioning groove of the towing body 41. The guiding cover 45 is provided with an opening matching the wire clamping groove 23. The guiding cover 45 is integrally in a horn-shaped structure and the large opening is away from the opening of the positioning groove.

[0035] The setting of the guiding cover 45 can position and guide the plug connector that is not fixed in the initial state, so that it can slide into the fixing groove 22 more smoothly and stably. Among them, the wire clamping groove 23 can limit the state of the wire harness relatively. That is, during the process of straightening the wire harness, the twisted or torsional wire harness will be kept vertical and in the same direction, that is, the plug connector whose shape is not kept downward due to the twisting of the wire harness is corrected, thereby improving the connection stability.

[0036] An anti-slip pad is provided in the opening of the wire clamping groove 23.

[0037] This can further limit the position and state of the wire harness.

[0038] An elastic member is provided at the bottom of the fixing groove 22.

[0039] Furthermore, setting the elastic member can enable the plug connector to have a certain displacement stroke in the fixing groove 22. At this time, the height dimension of the V-shaped groove portion 44 can be lengthened, so that the length of the V-shaped groove portion 44 is greater than the length of the wire harness after being straightened. In this way, after the wire harness is straightened, a certain pulling force will be generated between the wire harness and the solder joint of the plug connector, thereby being able to detect the stability of the solder joint between the wire harness and the plug connector.

[0040] Furthermore, the present application can also meet the detection requirements of plug connectors with different wire harness lengths by adjusting parameters or characteristic components such as replacing the outer sleeve 3, adjusting the distance between the platform 2 and the turntable 421, setting the telescopic guide rod 4, the transmission shaft 21, etc., but no specific restrictions and descriptions are made in the present application.

[0041] The above embodiments only exemplarily illustrate the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
