Abstract

The utility model relates to a commercial car is with OBD diagnosis socket assembly of resistant plug area secondary locking, its characterized in that: open the square -mouth shape column trompil for the terminal that has the slope on the socket, the terminal positioning groove sets up in the square -mouth shape column of socket for the terminal in the middle of the trompil, the socket afterbody is equipped with terminal secondary locking means, has the locking bolt between protecting crust and the socket, has the movable guard lid on the protecting crust, the sheath has the direction slope with terminal combination department. At the satisfied ISO 15031 that accords with 3 2004 requiring to change the terminal structure down, changing the Y type terminal that inserts the diagnosis socket originally into square -mouth shape column terminal, socket plug number of times is few before solving, the terminal is fragile, to inserting difficult scheduling problem, make the plug more easily, the plug number of times is more, the reliability is higher, have secondary locking means, the installation, maintain more low grade advantage of more convenient, cost of maintenance.

Description

A kind of commercial car plugs the obd diagnostic socket assembly with secondary locking with resistance to

Technical field

The utility model is related to a kind of commercial car with the resistance to obd diagnostic socket assembly with secondary locking for the plug, is a kind of business With car driver's cabin b type obd diagnostic socket assembly.

Background technology

Commercial-vehicle cab b type obd diagnostic socket assembly accept the interface that is connected with computer diagnostic instrument of engine ecu and , once loose contact or other are asked in passage, the communication between responsible engine ecu and computer diagnostic instrument and fault diagnosis Topic, will lead to the communication disruption between diagnostic equipment and engine ecu, engine ecu data cannot read, and failure code cannot be known And the problems such as cannot be carried out Pan Duan not demarcated.The socket assembly before adopting is import connector product, its connector inside end Son requires neat, somewhat for y type structure it is desirable to high to the dimensional requirement of the terminal of spigot diagnostic plug to the arrangement of spigot terminal Off-center, easily cause diagnostic socket terminal head portion to damage in swapping process, serious even directly exits terminal, or The faults such as loose contact, meanwhile, former female terminal exports as long strip type structure, plug terminal easily insert local derviation cause loose contact or Female terminal damages, and causes defective socket.

Content of the invention

The purpose of this utility model is to provide a kind of commercial car total with the resistance to obd diagnostic socket with secondary locking for the plug Become, be arranged on commercial-vehicle cab b type obd diagnostic socket assembly, meet under iso 15031-3-2004 requirement in satisfaction, change Become terminal structure, the y type terminal of original insertion diagnostic socket is changed to square opening shape column terminal, the front socket plug number of times of solution Less, terminal fragile, to slotting difficult the problems such as, so that plug is easier, plug number of times more, reliability is higher；With secondary lock Locking apparatus, install, safeguard more convenient, the more low advantage of maintenance cost.

The technical solution of the utility model is achieved in that a kind of commercial car is examined with the resistance to obd with secondary locking for the plug Disconnected socket assembly, be made up of socket, protecting crust and terminal it is characterised in that: sloping square opening shape column terminal is opened on socket Use perforate；Terminal position groove is arranged in the middle of the square opening shape column terminal perforate of socket；Hub tail is provided with the secondary lock of terminal Locking apparatus, have locking latch between protecting crust and socket, protecting crust carries movable guard lid；There is guiding sheath and terminal junction Slope.

Reliable contacts when good effect of the present utility model is to ensure that terminal injects, terminal combines more closely in socket, There is larger guiding slope sheath and terminal junction, insert beneficial to insertion terminal, insertion terminal arrangement are required relatively to put simultaneously Width, is hardly damaged terminal during pushing and plugging, reliability improves；Adopt secondary locking system in hub tail, prevent terminal outside The fault such as passively exit under power；Adopt drawing and pulling type locking system between socket and protecting crust, so that demolition, installation is joined easily, in the future Safeguard provides convenient；Diagnostic socket assembly structure is compact, and plug number of times improves, and is more prone to, contacts and more may be used with to spigot plug Lean on, be hardly damaged, easy to use, it is easy to safeguard, changes, meet and meet iso 15031-3-2004 correlation b class socket requirement.

Specific embodiment

Below in conjunction with the accompanying drawings embodiment of the present utility model is described in further detail.As Figure 1-5, Yi Zhongshang With automobile-used resistance to obd diagnostic socket assembly with secondary locking for the plug, be made up of socket, protecting crust and terminal it is characterised in that: slotting Sloping square opening shape column terminal perforate 1 is opened on seat；Terminal position groove 2 is arranged on the square opening shape column terminal of socket with opening In the middle of hole 1；Positioning baffle 3 meets the requirement of iso 15031-3-2004 correlation b class socket, and hub tail is provided with terminal locking Device 4；There is locking latch 5 between protecting crust and socket, protecting crust carries movable guard lid 6；Sheath is led with terminal junction To slope.

As shown in Figure 1, the utility model diagnostic socket 16 hole position adopts square opening shape structure, and sheath is had with terminal junction Certain guiding slope, in spigot Plug contact, plug terminal local offset within the specific limits, also can be reliable with socket Contact, and meet the requirement of iso 15031-3-2004, the maintenance of terminal is more convenient simultaneously.

As shown in Figure 2, the secondary locking system in socket rear portion 4 prevents terminal from passively exiting, simultaneously the installation to terminal and dimension Shield is convenient, reliable.

As shown in Figure 3, by protecting crust afterbody locking latch 5, the assembling to diagnostic socket is more square with maintenance and use Just, prevent socket from exiting under external force, reliability improves.

Shown in Fig. 4, diagnostic socket carries protecting crust, and the movable guard lid 6 on protecting crust plays dust-proof, protection to diagnostic socket Effect, simultaneously work as decoration, effect attractive in appearance.
